If you are living in Florida, working, starting a business, or building credit, and you do not have a Social Security Number, an ITIN may be one of the most important documents you can obtain. It will not give you work authorization, and it will not change your immigration status. But it opens doors that stay closed without it: filing a federal tax return, claiming dependents, opening certain bank accounts, building a U.S. credit history, and in some cases forming a business entity.
The process of applying for an ITIN through IRS Form W-7 is more straightforward than many people expect, but it has specific rules about documentation, submission methods, and timing that, if missed, can result in rejection and weeks of additional delay. One of those rules, about mailing your original passport to the IRS, surprises and worries almost everyone who encounters it. There is a way around it, and this guide explains exactly how it works.
This guide covers who needs an ITIN and why, how to complete Form W-7 section by section, which documents are accepted as proof of identity and foreign status, why working with a Certified Acceptance Agent is the most practical choice for most Florida applicants, how long the process takes, and how to handle renewal when your ITIN expires.

Key Takeaways
- An ITIN (Individual Taxpayer Identification Number) is a nine-digit tax processing number issued by the IRS to individuals who need a U.S. taxpayer ID but do not qualify for a Social Security Number.
- An ITIN is NOT work authorization. It is NOT proof of immigration status. Having one does not change your immigration situation.
- The most common reason to apply is filing a federal tax return. Other reasons include claiming dependents, opening bank accounts, and building U.S. credit history.
- Form W-7 is the only IRS form used to apply for an ITIN. Most applicants must submit it with a federal tax return.
- A passport is the single document that simultaneously proves both identity and foreign status, making it the preferred document for ITIN applications.
- If you mail your application directly to the IRS, you must send original documents, including your passport. The IRS will return them by mail, which takes additional time and carries risk.
- A Certified Acceptance Agent (CAA) can verify your original documents in person and return them to you immediately. You never mail your passport to the IRS.
- USCIS processing time for ITIN applications is approximately 7 to 11 weeks outside of peak tax season, and can extend up to 14 weeks or longer during peak season (January through April).
- Some ITINs expire if not used on a tax return for three consecutive years. Check whether yours needs renewal before filing.
What Is an ITIN and Who Needs One?
An Individual Taxpayer Identification Number, or ITIN, is a nine-digit number issued by the Internal Revenue Service for tax processing purposes. It always begins with the digit 9 and follows the format 9XX-XX-XXXX. The IRS issues ITINs specifically to individuals who are required to have a U.S. taxpayer identification number but do not qualify for, and are not eligible to obtain, a Social Security Number (SSN).
The key distinction is straightforward: if you have an SSN, you do not need an ITIN. If you do not have an SSN and are not eligible to obtain one, but you have a U.S. tax obligation or a legitimate reason to need a taxpayer ID, an ITIN is the correct identification number for you.
ITIN vs SSN: Key Differences
| Feature | ITIN | SSN |
| Issued by | IRS | Social Security Administration |
| Purpose | Tax processing only | Multiple: work authorization, benefits, credit |
| Work authorization | No | Yes |
| Immigration status proof | No | N/A |
| Who can get one | Anyone with a U.S. tax obligation who is ineligible for SSN | U.S. citizens, lawful permanent residents, eligible work visa holders |
| Expiration | Yes, under certain conditions | Never |
Who Can Apply for an ITIN
The IRS issues ITINs to several categories of individuals. The most common in Florida include undocumented immigrants who have U.S. tax obligations, nonresident aliens who earn U.S.-source income, foreign nationals who are spouses or dependents of U.S. citizens or residents, and individuals from other countries who have certain U.S. financial or tax obligations.
Having an ITIN does not mean you are authorized to work in the United States, and it does not make you eligible for Social Security benefits, the Earned Income Tax Credit (EITC), or most federal benefits. It is strictly a tax processing number.
Why You Might Need an ITIN
Filing Federal Tax Returns Without an SSN
The primary reason individuals apply for an ITIN is to comply with their U.S. federal tax filing obligation. If you earned income in the United States, you generally have a legal obligation to report it to the IRS, regardless of your immigration status. Filing a tax return creates a record of your tax compliance, which can be relevant in future immigration proceedings, though you should consult with an immigration attorney about how tax filings may relate to your specific situation.
Claiming Tax Dependents
If you are filing a U.S. tax return and want to claim a spouse or children as dependents, those individuals need a taxpayer identification number, either an SSN or an ITIN. Applying for ITINs for your dependents at the same time you apply for your own can simplify the process, though the document requirements differ slightly for dependent applicants.
Opening a Bank Account
Some financial institutions in Florida accept an ITIN as identification for opening certain types of bank accounts, including savings accounts, checking accounts, and in some cases, credit cards. Having a bank account is a foundational step for financial stability, building savings, and accessing other financial services. Not all banks accept ITIN holders, but many do, particularly banks that serve immigrant communities.
Building Credit History in the U.S.
An ITIN can be used to apply for certain credit products, including secured credit cards and some personal loans, depending on the lender. A U.S. credit history is valuable for accessing housing, auto financing, and other financial products. Building that history requires starting somewhere, and an ITIN is often the starting point for individuals who do not have an SSN.
Opening a Business or Forming an LLC
If you intend to open a business, form an LLC, or obtain an Employer Identification Number (EIN) for business purposes, you may need an ITIN as the responsible party’s taxpayer identification number. Many self-employed individuals and small business owners in Florida use their ITIN for business tax filings, self-employment tax reporting, and payroll purposes.
Step-by-Step: Filling Out Form W-7
Form W-7, Application for IRS Individual Taxpayer Identification Number, is available for free on the IRS website at irs.gov. It is the only form accepted by the IRS to apply for an ITIN. Errors or incomplete fields are the leading cause of ITIN application rejections, so accuracy is essential.
Reason for Applying (Boxes a through h)
At the top of Form W-7, you must check the box that best describes why you are applying for an ITIN. Only one box should be checked per application. The options are:
| Box | Reason |
| a | Nonresident alien required to get an ITIN to claim a tax treaty benefit |
| b | Nonresident alien filing a U.S. federal tax return |
| c | U.S. resident alien filing a U.S. federal tax return (based on days of physical presence) |
| d | Dependent of a U.S. citizen, resident alien, or nonresident alien |
| e | Spouse of a U.S. citizen or resident alien |
| f | Nonresident alien student, professor, or researcher filing or claiming an exception |
| g | Dependent or spouse of a nonresident alien visa holder |
| h | Other (less common, used for specific treaty situations or third-party withholding) |
Most Florida applicants filing a tax return will check Box b (nonresident alien) or Box c (U.S. resident alien based on the Substantial Presence Test). Spouses and dependents of U.S. citizens or residents typically check Box d or Box e.
Personal Information and Foreign Status
The form requires your complete legal name, mailing address, date and country of birth, country of citizenship, and your foreign tax identification number if one exists in your home country. If you have previously held an ITIN or an Internal Revenue Service Number (IRSN), you must provide that number and the name under which it was issued. Do not leave fields blank without a specific reason.
Mailing Address vs Foreign Address
If you have a U.S. mailing address, enter it in the designated field. The IRS uses this address to mail your ITIN assignment letter back to you. If you also have a foreign address, enter it in the separate foreign address field. Both can be listed. Use the address where you will reliably receive mail from the IRS.
Required Signatures
The applicant must sign and date Form W-7. If a Certified Acceptance Agent is assisting you, they will complete the acceptance agent section of the form with their credentials and certification information. If someone else is signing on your behalf, they must have authorization to do so and their information must be included.
Documents Accepted as Proof of Identity and Foreign Status
The IRS requires documentation that simultaneously proves two things: your identity and your foreign status. Most documents prove only one of those things, which is why the document combination matters.
Passport (The Single Most Common Document)
A passport is the only document that independently proves both identity and foreign status in a single document. The IRS considers it the preferred document for ITIN applications. If you have a valid passport, it is almost always the right choice for your ITIN application.
One critical rule: the IRS requires original documents or certified copies issued by the official issuing authority. Notarized photocopies are not accepted. This means that if you apply by mail directly to the IRS, you must send your original passport, which the IRS will hold for a period before returning it to you. For most people in Florida, this is not acceptable: you may need your passport for travel, identification, or other purposes during that period.
Combinations of Documents If You Don’t Have a Passport
If you do not have a passport or prefer not to use it, the IRS accepts combinations of other documents, but you need at least two: one that establishes identity and one that establishes foreign status. The IRS recognizes 13 types of supporting documents total.
Common combinations include:
| Identity Document | Foreign Status Document |
| National identity card (with photo, name, DOB, expiration) | U.S. visa |
| Driver’s license (foreign) | Foreign voter registration card |
| Civil birth certificate | Medical records (for dependents/minor children) |
| Military ID | Foreign school records |
Important: for dependent children, birth certificates combined with medical or school records are frequently used when a passport is not available.
The Certified Acceptance Agent (CAA) Advantage
A Certified Acceptance Agent (CAA) is an individual or entity authorized by the IRS to verify original documents on behalf of ITIN applicants, certify copies of those documents, and submit Form W-7 applications to the IRS. Working with a CAA is the option that most Florida families and individuals should seriously consider, for one very important reason: your original documents never leave your hands.
Why You Should Never Mail Your Original Passport to the IRS
When you apply for an ITIN by mailing your application directly to the IRS, the rules require you to include your original documents, including your passport. The IRS processes your application and then mails the documents back to you, which can take additional weeks beyond the processing time for the ITIN itself.
During that period, your passport is at the IRS facility in Austin, Texas. You cannot travel internationally. You cannot present your passport as identification. If the package is lost in transit, the consequences are significant: replacing a foreign passport typically requires contacting your home country’s consulate, which takes time, fees, and documentation.
For families in Florida who may need their passport for an upcoming trip, who cannot be without identification for weeks, or who simply do not want to take the risk of a lost document, this is not a viable option.
How a CAA Certifies Your Passport in Person
When you work with a Certified Acceptance Agent, the process works differently. You bring your original documents to the CAA in person. The CAA examines the originals, verifies their authenticity, makes certified copies, and completes a Certificate of Accuracy that accompanies your application. Your original passport is handed back to you immediately after the CAA’s review. You walk out with your passport.
The CAA submits the certified copies and the Certificate of Accuracy to the IRS along with your completed Form W-7 and your attached tax return (when required). The IRS accepts the CAA’s certification without requiring the original. This is the primary practical advantage of using a CAA, and for most applicants, it is decisive.
CAAs also review your completed Form W-7 for errors before submission, which reduces the risk of rejection due to incomplete or incorrect information.
How Long Does the ITIN Process Take?
The IRS processes ITIN applications within approximately 7 weeks outside of peak season. During peak processing periods, which run from January 15 through April 30, processing times extend to 9 to 11 weeks. Some sources report processing can extend to 14 weeks or longer during peak season.
The processing clock starts from the date the IRS receives your complete, correct application, not from the date you mail it. Applications with missing documents, errors on the W-7, or incomplete tax returns attached are frequently rejected and must be resubmitted, which restarts the clock.
| Submission Method | Processing Time | Documents Required |
| Mail directly to IRS | 7–11 weeks standard, up to 14+ weeks peak | Original documents required; returned by mail |
| Through Certified Acceptance Agent (CAA) | 7–11 weeks standard (IRS processing same) | Originals verified in person; returned immediately |
| IRS Taxpayer Assistance Center (TAC) | 7–11 weeks standard | Originals verified in person; returned immediately |
If you have a tax filing deadline approaching and have not yet received your ITIN, note that you can file your tax return with Form W-7 attached, using the ITIN number field blank for the ITIN you are applying for. The IRS processes both simultaneously once the ITIN is assigned.
When and How to Renew an Expired ITIN
Not all ITINs expire, but many do under certain circumstances. An ITIN expires if it has not been used on a federal tax return for three consecutive tax years. Additionally, USCIS has issued notices about specific ITIN middle-digit ranges that have been deactivated in batches as part of IRS efforts to update the ITIN program.
To check whether your ITIN is still active, look at your most recent tax return. If you have filed a return including your ITIN in the past three years, it should be active. If you have not filed, or if you received a notice from the IRS that your ITIN has expired, you will need to renew it.
Renewal is done by submitting Form W-7 with the “Renew an Existing ITIN” box checked at the top of the form. When renewing, you do not need to attach a tax return unless you are filing one at the same time. The same document verification process applies for renewal as for an initial application.
ITIN and Your Tax Return: Filing Together
For the majority of applicants, Form W-7 must be submitted together with a federal tax return. The tax return is the mechanism that establishes your U.S. tax obligation, which is what justifies issuing the ITIN. There are limited exceptions to this requirement, such as when a third party, like a mortgage company or bank, is required to file a U.S. information return on your behalf and needs your ITIN for that purpose.
When filing together, attach your completed Form W-7 to the front of your tax return. Leave the social security number field blank or write “ITIN TO BE ASSIGNED” if required. Submit the complete package, including your identity documents, to the IRS Austin address listed in the W-7 instructions, or through a CAA.

Frequently Asked Questions
Can I apply for an ITIN if I am undocumented? Yes. Immigration status does not disqualify you from applying for an ITIN. The IRS issues ITINs based on your tax filing obligation, not your immigration status. Many undocumented individuals living and working in the United States have a legal obligation to file federal tax returns and use an ITIN to do so. For questions about how tax filing may interact with your specific immigration situation, consult with an immigration attorney.
Does having an ITIN help with my immigration case? An ITIN by itself does not confer any immigration benefit or status. However, having a documented history of tax compliance, which an ITIN enables, may be considered as a positive factor in certain immigration applications and proceedings. Consult with a licensed immigration attorney for guidance on how your specific tax filing history may be relevant to your immigration case.
Can I open a bank account with an ITIN in Florida? Many banks and credit unions accept an ITIN as identification to open certain accounts. Availability varies by institution, and not all banks offer this service. Research your options before applying and call ahead to confirm what the specific bank requires for ITIN holders.
What happens if I already have an ITIN but now qualify for an SSN? If you have been assigned an SSN after previously having an ITIN, you must use the SSN going forward. Notify the IRS by writing to the ITIN Unit and providing your SSN and ITIN number so the IRS can link your records. The IRS will assign all future tax filing to the SSN and void the ITIN.
Can children born in the United States to undocumented parents get an ITIN? Children born in the United States are U.S. citizens and are eligible for a Social Security Number, not an ITIN. An ITIN would not be appropriate for a U.S.-born child. However, children who are not U.S. citizens and are dependents of a taxpayer filing a U.S. return may need an ITIN to be claimed as dependents on that return.
