A photocopy that looks perfectly official can still sink a Form W-7 application. The problem is not image quality; it is whether the IRS recognizes who authenticated the document. Originals, issuing-agency-certified copies, and ordinary notarized copies are not interchangeable. Today, this guide will help you choose the safest submission route, identify acceptable identity documents, and avoid mailing away a passport when a better option exists. In about 15 minutes, you can build a document plan that protects your travel schedule, reduces rejection risk, and keeps your ITIN application from becoming an expensive paper boomerang.
The Fast Answer: What the IRS Accepts
For a standard Form W-7 application, the IRS generally requires supporting identification documents in one of two forms:
- The original document, such as an original passport.
- A certified copy issued or certified by the government agency that originally issued the document.
An ordinary photocopy is not enough. A copy certified only by a private notary is generally not accepted as a substitute for an issuing-agency-certified copy. The stamp must carry the authority the IRS recognizes, not merely the authority to witness signatures.
There are also in-person alternatives. Certain IRS Taxpayer Assistance Centers can authenticate most documents and return them at the appointment. An IRS-authorized Certifying Acceptance Agent may also review and authenticate permitted documents, although the rules differ for primary applicants, spouses, and dependents.
- Originals are generally acceptable.
- Issuing-agency-certified copies are generally acceptable.
- Ordinary notarized photocopies are generally not acceptable.
Apply in 60 seconds: Look at the certification page and identify the exact agency that placed the original seal or stamp.
I have seen applicants spend more time choosing a courier envelope than checking the certification itself. The envelope arrived beautifully. The document inside was still unacceptable. Bureaucracy has a dry sense of humor.
What “issuing agency” means
The issuing agency is the government authority that created or issued the original document. For a passport, that is normally the national passport authority or another authorized government office. For a birth certificate, it may be a civil registry, vital records office, municipality, province, state, or comparable authority.
A bank, tax preparer, translation company, shipping store, or neighborhood notary did not issue your passport. Their stamp may be legally useful for another purpose, but it does not automatically create an IRS-acceptable certified copy.
What an acceptable certified copy should show
The certified copy should clearly indicate that it is an exact copy of the original and should carry an official certification, stamp, or seal from the issuing agency. A photocopy of an agency’s seal may not be enough when the IRS expects an original certification mark on the submitted copy.
If the certification wording is vague, ask the agency whether the document is specifically an officially certified copy produced or authenticated by that agency. “Certified-looking” is not a legal category, despite its popularity at copy shops.
Who This Guide Is For and Not For
This guide is for people preparing or renewing an Individual Taxpayer Identification Number application using Form W-7. It is particularly useful when the applicant has a foreign passport, lives outside the United States, must attach a federal tax return, or cannot comfortably surrender an original identity document for processing.
This guide is for you if:
- You need an ITIN but are not eligible for a Social Security number.
- You are choosing between mailing an original passport and obtaining a certified copy.
- You are considering an IRS Taxpayer Assistance Center or Certifying Acceptance Agent.
- You are applying for a spouse or dependent and need to understand the stricter document rules.
- Your name, birth date, nationality, or entry information differs across documents.
- You received an IRS notice asking for additional or replacement identification documents.
This guide is not a substitute for individualized tax advice
Form W-7 rules depend on the applicant’s reason for requesting an ITIN, the exception claimed, the attached tax return, the applicant category, and the documents available. Treaty claims, withholding exceptions, foreign student situations, dependent residency requirements, and prior ITIN records can add another layer.
This article is general educational information. It is not legal or tax advice, and it does not guarantee that the IRS will accept a particular application. Always use the current Form W-7 and instructions in effect when you file.
Someone once showed me a five-year-old W-7 checklist saved as a phone screenshot. It was neat, color-coded, and quietly obsolete. Tax paperwork ages less like wine and more like milk left near a sunny window.

Certified Copy vs Original: The Real Difference
An original document is the physical document issued to you by the relevant authority. A certified copy is a separate copy that the original issuing agency confirms is an exact copy of the original.
The important distinction is authority. A notary may certify that a person signed a statement, appeared before the notary, or swore that a copy is accurate. That does not necessarily mean the passport office, civil registry, or licensing authority certified the copy.
Side-by-side comparison
| Document version | Who authenticates it? | Usually accepted by IRS? | Main concern |
|---|---|---|---|
| Original passport or original civil document | Original government issuer | Generally yes | Loss, damage, travel interruption, and return timing |
| Issuing-agency-certified copy | Agency that issued the original | Generally yes | Certification wording, seal, completeness, and agency authority |
| Ordinary photocopy | Nobody | Generally no | No recognized authentication |
| Privately notarized photocopy | Private notary | Generally no | Notary may not be the issuing agency |
| Copy authenticated through eligible CAA procedures | IRS-authorized Certifying Acceptance Agent | Potentially, subject to applicant and document limits | CAA authority differs for dependents and certain documents |
| Copy authenticated at an eligible IRS TAC | Participating IRS office | Potentially, subject to service limits | Appointment and location availability |
Why “notarized” and “certified” cause confusion
In everyday speech, people use “certified,” “authenticated,” and “notarized” as though they describe the same process. They do not. A document can be notarized without being certified by its issuing agency. It can also be certified by an issuing agency without involving a private notary.
The safest question is not, “Does this have a stamp?” Ask, “Did the agency that issued this document certify this exact copy?” Stamps are costumes. Authority is the actor underneath.
Visual Guide: Follow the Authentication Trail
Find the government authority that created the passport, certificate, license, or record.
Confirm that the issuing agency certified the submitted copy as exact and complete.
Primary applicants, spouses, and dependents can face different authentication limits.
Use a TAC or eligible CAA when mailing an essential original would create serious risk.
Show me the nerdy details
The IRS uses supporting documents to establish two separate facts: identity and foreign status. Some documents establish both; others establish only one. A passport is normally the most efficient standalone document because it can establish both categories. When no passport is submitted, applicants generally need a combination of documents that collectively proves the required facts. Certain dependents must also establish US residency unless an exception applies. The authentication route does not repair a document that fails to prove the underlying fact.
Which W-7 Supporting Documents Are Acceptable?
The IRS recognizes a limited set of documents for proving identity, foreign status, or both. The current Form W-7 instructions should control your final selection, but the commonly listed documents include the following:
- Passport
- National identification card
- US driver’s license
- Civil birth certificate
- Foreign driver’s license
- US state identification card
- Foreign voter registration card
- US military identification card
- Foreign military identification card
- School records for eligible applicants
- Medical records for eligible applicants
- US Citizenship and Immigration Services photo identification
- Visa issued by the US Department of State
Submitting a document from the list does not automatically make the package sufficient. The document must be valid for the relevant category, properly authenticated, legible, and consistent with the information on Form W-7.
Why a passport is usually the cleanest option
A passport is generally the only standalone document that can establish both identity and foreign status. Without one, you may need at least two acceptable documents, and the combination must cover both requirements.
That efficiency is why passports dominate W-7 discussions. It is also why applicants become nervous about mailing one. A passport is both the cleanest solution and the document most likely to be needed at an airport next Tuesday. Paperwork enjoys dramatic timing.

School and medical records have narrow roles
School and medical records are not universal substitutes for adult identity documents. Their use is commonly limited by age and applicant circumstances. They may also need to contain specific information, such as the applicant’s name, address, relevant dates, and institutional details.
Do not add a school record merely because it has a photograph and a cheerful logo. Ask what legal requirement the record proves. Every page in a W-7 package should have a job.
Internal reading for document consistency
If your name appears differently across government records, review this practical guide to resolving name discrepancies across passports and official documents. The same discipline applies to Form W-7: identify the mismatch before an examiner has to guess which version is correct.
Four Ways to Submit W-7 Documents
You do not have to treat mailing an original passport as the default. There are four main routes, each with a different balance of cost, convenience, appointment availability, and document risk.
Route 1: Mail original documents to the IRS
This route can be straightforward when the original document is not urgently needed. The W-7 package is generally sent to the address listed in the current instructions, often with the required federal tax return or qualifying exception evidence.
The advantage is simplicity. The disadvantage is separation from the original document while the application is processed and the document is returned. International mail, upcoming travel, visa renewals, banking requirements, and local identification rules can make that separation costly.
The IRS states that original documents are returned to the mailing address on Form W-7. An applicant may be able to include a prepaid courier or express envelope for document return. Check the latest instructions and courier requirements before relying on that option.
Route 2: Mail issuing-agency-certified copies
This route allows you to retain the original while sending a certified copy created or authenticated by the issuing agency. It is often attractive for applicants abroad, although obtaining the certification may involve an embassy, consulate, passport authority, civil registry, or other government office.
Before paying a fee, ask three questions:
- Is this office the issuing agency or legally authorized to certify copies for the issuing agency?
- Will the certification state that the copy is exact and complete?
- Will the submitted copy carry an original official stamp, seal, or certification?
I once watched an applicant order three “certified copies” from three different vendors because each website used reassuring gold-seal graphics. None was the passport issuer. Gold pixels remain pixels.
Route 3: Visit a participating IRS Taxpayer Assistance Center
Certain IRS Taxpayer Assistance Centers provide ITIN document services by appointment. A participating office may review Form W-7, authenticate most supporting documents, return authenticated originals at the end of the appointment, and forward the application package for processing.
This can sharply reduce the risk of mailing an original passport. However, not every IRS office provides ITIN authentication, appointment availability varies, and some document categories have limitations. School and medical records for dependents may require special handling.
Route 4: Use an IRS-authorized Certifying Acceptance Agent
A Certifying Acceptance Agent, commonly called a CAA, can review the application and authenticate documents within the scope of the agent’s IRS authorization. The CAA generally prepares a Certificate of Accuracy to accompany the application.
CAA services may be provided by accounting firms, tax professionals, universities, financial institutions, nonprofit organizations, or other approved entities. Some charge fees. Others limit service to clients, students, employees, or members of a particular community.
Do not confuse a Certifying Acceptance Agent with an ordinary Acceptance Agent. A standard Acceptance Agent may assist with the application but may not have the same authority to authenticate documents. One extra word in the title can determine whether your passport stays in your hand.
Submission route decision card
Choose Your Lowest-Risk Route
Mail the original when: You have no travel or identification need during the expected processing period, secure mailing is available, and replacement would not create severe hardship.
Use an issuing-agency-certified copy when: The issuer can provide a clearly acceptable certification at a reasonable cost and you need to retain the original.
Use a TAC when: You can obtain an appointment at an office offering ITIN services and want the IRS to return authenticated documents immediately.
Use a CAA when: Appointment convenience, application review, or guided document authentication is worth the potential service fee.
- Travel soon? Avoid mailing an essential passport.
- Using a CAA? Verify that the person is currently IRS-authorized.
- Using a TAC? Confirm that the location offers ITIN document authentication.
Apply in 60 seconds: Write your next unavoidable passport-use date on the top of your W-7 checklist.
Passport Rules, Entry Dates, and Dependent Traps
A passport solves many W-7 documentation problems, but it does not solve every one. Applicants often discover this only after assembling a tidy package around the assumption that “passport equals finished.”
When an entry date matters
Certain applicants, particularly dependents, may need documentation showing US residency. A passport without a date of entry may not establish that requirement by itself. Additional records may be needed unless the dependent falls within an applicable exception.
The exact rule depends on who is applying, where the person resides, the claimed tax benefit, and the exception involved. Do not add a handwritten travel date to a passport copy and hope it becomes official evidence. Ink is industrious, but it cannot promote itself to immigration record.
Primary applicant, spouse, and dependent rules are not identical
A CAA may generally authenticate a broad range of permitted documents for primary and secondary applicants, subject to program rules. For dependents, the CAA’s authority is narrower. Current IRS guidance indicates that a CAA may authenticate passports and civil birth certificates for dependents, while original or issuing-agency-certified copies of other dependent documents may need to be sent to the IRS.
This distinction catches families who assume one appointment resolves every document for every household member. Ask the CAA to identify which documents will be authenticated and which, if any, must leave your possession.
Dependent residency evidence
A dependent may need records showing residence in the United States for the required period. Depending on age and circumstances, suitable evidence might involve medical, school, bank, rental, utility, or government records, but the current W-7 instructions and the tax benefit claimed must guide the choice.
Residency evidence should show the dependent’s name, relevant address, and dates covering the required period. A parent’s utility bill with no dependent named may prove the parent lives there. It does not automatically prove the child does.
Quick dependent risk scorecard
| Risk signal | Low | Medium | High |
|---|---|---|---|
| Passport | Valid and complete | Expires soon | Expired, damaged, or identity mismatch |
| US entry evidence | Clearly documented | Available but inconsistent | Required but absent |
| Residency records | Name, address, and dates align | Some months or details missing | Only another household member is named |
| CAA document authority | Confirmed in writing | Verbal assurance only | Provider cannot explain dependent limits |
Decision cue: One high-risk signal is enough to pause filing. A delayed application is frustrating; a rejected application followed by another document cycle is frustration wearing formal shoes.
The Document-Matching Check Before You File
Even an authentic original document can create trouble when its information conflicts with Form W-7. Before submitting anything, compare every identity field character by character.
Match these fields across the package
- Legal name and any name at birth
- Date of birth
- Country of birth
- Country or countries of citizenship
- Foreign address
- US address, when applicable
- Visa type and number, when applicable
- Date of entry into the United States, when required
- Passport or identification number
- Document expiration date
- Prior ITIN or IRS-assigned number
Small formatting differences are not always fatal. A missing surname, reversed family and given names, different transliteration, changed marital name, or conflicting birth date is more serious.

Document Reconciliation Worksheet
| Field | Form W-7 | Identity document | Tax return or exception record |
|---|---|---|---|
| Full name | ________ | ________ | ________ |
| Birth date | ________ | ________ | ________ |
| Citizenship | ________ | ________ | ________ |
| Address | ________ | ________ | ________ |
| Document number | ________ | ________ | Not applicable |
Rule: Do not silently choose one version when the records disagree. Determine why the difference exists and what supporting explanation or correction is appropriate.
Translations and non-English documents
The IRS may need enough information to evaluate a document written in another language. The current instructions, IRS correspondence, applicant circumstances, or assisting professional may indicate whether a translation is required or advisable.
A translation does not replace the original or certified copy. It explains the document’s content. Think of it as a map beside the building, not the building itself.
Check the attached tax return too
Most W-7 applications are submitted with a federal income tax return unless an exception applies. The name and taxpayer information on that return should align with Form W-7 and the supporting documents.
For related preparation issues, see this guide to checking Form W-2 and 1099 information before filing. A clean identity package can still stumble when the attached tax records use a different spelling or taxpayer profile.
- Compare names character by character.
- Check dates in the same month-day-year format.
- Resolve major differences before mailing.
Apply in 60 seconds: Circle every field that appears differently on two documents, including spaces and surname order.
Common W-7 Supporting Document Mistakes
1. Sending a notarized copy instead of an issuing-agency-certified copy
This is the classic error. A private notary may have followed local law perfectly, yet the copy still may not satisfy IRS W-7 standards. The question is not whether the notary is legitimate. The question is whether that form of certification is one the IRS accepts for this purpose.
2. Sending a copy of the certified copy
An applicant receives an acceptable certified copy, scans it, prints the scan, and mails the printout. The new printout may show an image of the official seal rather than the original certification placed on the submitted document.
It feels harmless because the information is identical. The authentication trail is not.
3. Cropping passport pages
Do not crop away page edges, machine-readable zones, document numbers, stamps, blank facing pages required by the certifying authority, or certification attachments. A tidy crop can remove the very feature that proves completeness.
4. Mailing an original immediately before travel
Processing and return timing can vary. If you will need the passport within the next several weeks, explore a participating TAC, a qualified CAA, or an issuing-agency-certified copy instead.
5. Assuming every acceptance agent can certify documents
An Acceptance Agent and a Certifying Acceptance Agent do not have identical authority. Confirm the provider’s current IRS status and ask whether the agent will authenticate your exact document for your exact applicant category.
6. Ignoring dependent limitations
A CAA who can authenticate many documents for the primary applicant may have narrower authority for a dependent. Families should ask about each person separately rather than treating the package as one unit.
7. Submitting an expired or damaged document without checking the rule
Do not assume that an expired passport will be accepted because the photograph remains recognizable. Validity, expiration, and document condition matter. Consult the current instructions or obtain case-specific help.
8. Using inconsistent names without explanation
Marriage, transliteration, cultural naming conventions, and clerical errors can create legitimate differences. Legitimate does not mean self-explanatory. Gather the record that connects the names or correct the application where appropriate.
9. Forgetting the tax-purpose evidence
Identity documents prove who you are. They do not, by themselves, prove why you need an ITIN. Most applicants attach a federal tax return; others must satisfy a specific exception with the required supporting evidence.
10. Mailing to an address copied from an old article
Use the mailing address in the current Form W-7 instructions. Addresses, service arrangements, and courier directions can change. Your package should not take a nostalgic tour of former IRS routing centers.
11. Failing to keep a complete application copy
Keep a copy of Form W-7, the attached return, exception evidence, cover letters, document descriptions, mailing receipt, tracking number, and any prepaid return-envelope details. Do not retain unsecured copies of identity documents longer than necessary, and store them carefully.
12. Resubmitting blindly after an IRS notice
Read the notice line by line. Determine whether the IRS questioned identity, foreign status, residency, document certification, missing information, or the tax purpose. Sending the same package again with a brighter cover sheet rarely changes the result.
If the IRS asks you to verify your identity through a separate notice process, this guide to IRS identity verification notices can help you distinguish a W-7 document problem from a return-verification issue.
Short Story: The Copy That Looked Certified
Short Story: The Passport Copy With Three Stamps
Mina needed an ITIN for a return that included her husband as the primary filer. She visited a notary, a translation office, and a shipping center. Her passport copy collected three stamps, two signatures, and enough ribbon to win a county fair. She reasonably believed that more authentication meant more acceptance.
The problem was simple: none of those businesses had issued her passport. The certification chain never reached the government passport authority. Her preparer caught the issue before mailing, but Mina had already spent money and lost a week.
She eventually booked an appointment with a participating IRS Taxpayer Assistance Center. The office reviewed the W-7 package, authenticated the eligible documents, and returned the passport during the appointment.
The practical lesson was not “always use a TAC.” It was narrower and more useful: identify the authority before paying for the stamp. One correct certification beats a small parade of decorative ones.
- Verify the issuer first.
- Confirm the provider’s IRS role.
- Choose the route before purchasing services.

When to Seek Professional or IRS Help
A straightforward W-7 application can often be prepared without extensive professional assistance. Help becomes more valuable when the document issue overlaps with eligibility, treaty claims, prior taxpayer numbers, immigration records, dependent residency, or a filing deadline.
Seek help before filing when:
- You may be eligible for a Social Security number.
- You previously received an ITIN but cannot locate it.
- Your passport and birth record contain materially different names or dates.
- You are claiming a dependent and cannot clearly prove required residency.
- You are using a W-7 exception instead of attaching a federal tax return.
- You need an original passport for travel, immigration, banking, or employment purposes soon.
- You are unsure whether a foreign certification was issued by the proper authority.
- The applicant is a minor and school or medical records are involved.
- The tax return has a near deadline or affects a time-sensitive tax benefit.
- The IRS has already rejected or suspended the application.
Who can help?
A participating IRS Taxpayer Assistance Center may provide document authentication and application support. An authorized CAA may offer document review and certification services within the agent’s permitted scope. An enrolled agent, certified public accountant, or tax attorney may help with the federal tax purpose, return position, exceptions, and response strategy.
Credentials should match the problem. A courier can deliver the package, but it should not decide whether your treaty exception is valid. A tax preparer may understand the return but may not be a CAA. One professional can be excellent without being authorized to perform every role.
Quote-prep list for a CAA
Ask These Questions Before Paying a CAA
- Are you currently listed or authorized by the IRS as a Certifying Acceptance Agent?
- Will you authenticate my specific document?
- Does your authority differ because the applicant is a dependent?
- Which original documents, if any, must still be mailed to the IRS?
- Will you review the Form W-7 reason and attached tax-purpose evidence?
- What is the total fee, including each family member?
- What happens if the IRS requests additional documents?
- Will I receive a copy of the submitted application package?
Cost comparison without false precision
IRS assistance at a Taxpayer Assistance Center does not generally involve a private preparation fee, but transportation, appointment availability, and time away from work can create indirect costs. Issuing agencies may charge certification fees. CAAs may charge professional fees that vary widely by location and service scope.
Compare the total cost, not just the quoted fee:
- Document certification fees
- Embassy or consular appointment costs
- CAA preparation and family-member fees
- Courier and tracking charges
- Travel to an IRS office
- Potential cost of replacing a lost passport
- Potential cost of missing travel or a filing deadline
FAQ
Does the IRS accept notarized passport copies for Form W-7?
Generally, no. The IRS normally requires the original document or a copy certified by the government agency that issued the document. A private notary’s certification is not usually a substitute for issuing-agency certification.
Can I send a regular photocopy of my passport with Form W-7?
A regular photocopy is generally not accepted as supporting identification by itself. Use the original, an issuing-agency-certified copy, eligible authentication through a participating IRS Taxpayer Assistance Center, or an authorized CAA process where permitted.
What makes a passport copy IRS-certified?
The copy should be provided or certified as an exact copy by the passport’s issuing government authority or another authority recognized by the issuing government for that function. It should carry the appropriate official certification, stamp, or seal. A copied image of a seal may not replace an original certification on the submitted copy.
Will the IRS return my original passport?
The IRS states that original documents submitted with a W-7 application are returned to the mailing address listed on Form W-7. Return timing can vary. Applicants may be permitted to include a prepaid express or courier envelope, but they should follow the current instructions carefully.
How long should I expect the IRS to keep my original documents?
Processing times vary by filing season, applicant location, application completeness, and IRS workload. Do not plan around the shortest advertised estimate. If you may need the document within roughly the next two months, the IRS advises considering an in-person TAC or CAA route rather than mailing the original.
Can a Certifying Acceptance Agent keep me from mailing my passport?
Often, yes, when the CAA is authorized to authenticate that document for that applicant. Restrictions apply, especially for dependents and particular document types. Confirm the scope before the appointment.
Can any tax preparer certify my W-7 documents?
No. Tax preparation credentials do not automatically include CAA authority. The preparer must be an IRS-authorized Certifying Acceptance Agent to perform CAA authentication functions.
Is an Acceptance Agent the same as a Certifying Acceptance Agent?
No. Both may assist with ITIN applications, but a Certifying Acceptance Agent has additional authority to authenticate permitted supporting documents and submit a Certificate of Accuracy. Always verify the provider’s exact status.
Can an embassy certify my passport copy for the IRS?
Potentially. An embassy or consulate may be able to provide or arrange a copy certified by the issuing government, but services vary by country and post. Ask whether the certification meets the issuing-agency requirement for an IRS ITIN application.
Do I need more than one document if I do not use a passport?
Usually, yes. A passport can generally establish both identity and foreign status. Without a passport, you normally need a combination of acceptable documents that collectively proves both.
Can I use an expired passport for Form W-7?
Do not assume an expired passport will qualify. Check the current W-7 instructions and obtain guidance for the applicant’s facts. Document validity, applicant age, renewal status, and available alternatives may affect the answer.
What if the name on my passport differs from my tax return?
Resolve the discrepancy before filing. The appropriate solution may involve correcting the return, using the current legal name, documenting a marriage or legal name change, or explaining a transliteration difference. Do not submit conflicting identities without a clear paper trail.
Does a passport prove US residency for a dependent?
Not always. A passport establishes identity and foreign status, but a dependent may also need evidence of US residency. A passport lacking relevant US entry information may not satisfy that separate requirement.
Can I submit Form W-7 without a tax return?
Only when you qualify for a recognized exception and include the required evidence for that exception. Most applicants demonstrate a federal tax purpose by attaching a federal income tax return.
What should I do if the IRS rejects my supporting documents?
Read the notice carefully and identify the stated defect. It may concern certification, expiration, missing residency evidence, identity inconsistency, or the W-7 reason. Respond by the stated deadline and do not simply resend the same defective copy.
Final 15-Minute Checklist
The uncertainty at the beginning of this process usually comes from one muddy word: “certified.” Once you separate an issuing-agency-certified copy from an ordinary notarized photocopy, the rest becomes a sequence of smaller decisions.
Use the next 15 minutes to perform this final check:
- Confirm that the applicant is not eligible for a Social Security number.
- Identify the federal tax purpose and correct Form W-7 application reason.
- Determine whether a tax return or exception evidence must be attached.
- List the documents proving identity and foreign status.
- Confirm whether dependent residency evidence is required.
- Choose original, issuing-agency-certified copy, TAC, or CAA submission.
- Verify that every certification comes from an authorized source.
- Compare names, dates, citizenship, addresses, and document numbers.
- Check the current IRS mailing address or appointment instructions.
- Copy the complete package and save mailing or appointment records securely.
Do not mail an essential passport simply because it is the first method described on a checklist. Choose the route that satisfies the IRS rule while respecting your travel, immigration, family, and identification needs. Good tax preparation is rarely dramatic. It is the quiet art of removing avoidable problems before they learn your mailing address.
- Verify who certified the document.
- Verify what the document proves.
- Verify that you can live without the original during processing.
Apply in 60 seconds: Write “issuer, purpose, match, return risk” on your checklist and answer each item for every document.
