Applying for an Individual Taxpayer Identification Number costs nothing at the IRS window — Form W-7 is free to file — but the full price of getting an ITIN in hand usually runs somewhere between a few dollars in postage and several hundred dollars once you factor in tax preparation, professional help, certified document copies, and translations. Where you land in that range depends on whether you handle the paperwork yourself, whether you already have a valid passport, and whether your supporting documents are in English.
The IRS Charges Nothing for Form W-7
There is no filing fee for Form W-7, whether you’re applying for a new ITIN or renewing an expired one. The form and its instructions are free to download from the IRS website, and the agency charges nothing to process the application, no matter how you submit it: by mail, through an acceptance agent, or in person at a Taxpayer Assistance Center.
Every other cost in this article is something you pay to a third party — a preparer, a translator, a foreign records office, the Postal Service — not to the IRS.
You Usually Have to Attach a Tax Return
Most first-time applicants can’t send Form W-7 on its own. The IRS requires a completed federal income tax return attached to the application, unless you fit one of a narrow set of exceptions such as passive income subject to third-party withholding, tax treaty benefits on wages or scholarships, or U.S. mortgage interest reported by a lender.1Internal Revenue Service. Instructions for Form W-7 (12/2024)
If none of those apply, budget for tax preparation as part of your ITIN costs. Some preparers include W-7 completion at no extra charge when they’re already filing your return, which can quietly eliminate one of the bigger line items.
What Professional Help Costs
The IRS authorizes two kinds of agents to help with ITIN applications, and the difference matters for both price and your documents.
A Certifying Acceptance Agent (CAA) can review your Form W-7, authenticate your identity documents on the spot, and hand your originals back before you leave. You never mail your passport to the IRS. CAA fees generally run between $200 and $500 per applicant, and more for complex situations.
A standard Acceptance Agent (without the “Certifying” designation) can review your paperwork but cannot authenticate documents. Your originals still get mailed to the IRS.2Internal Revenue Service. ITIN Acceptance Agents
Independent tax preparers and accounting firms that aren’t IRS-authorized agents can still help you complete the form; they simply can’t authenticate documents. Standalone W-7 preparation from a tax professional typically runs $50 to $200, depending on location. Ask upfront whether the fee covers document authentication or just form completion, because that answer determines whether you’ll also be mailing your originals.
Supporting Documents
Every ITIN applicant needs proof of identity and foreign status. A valid passport is the single easiest document to use, because the IRS accepts it as proof of both.3Internal Revenue Service. ITIN Supporting Documents Without a passport, you need two documents instead — for example, a national identity card plus a birth certificate — and certified copies from the issuing agency cost money that varies widely by country and document type.
For dependents, the rules shift by age. Children under six can use medical records as identity proof. Dependents under 24 who are students can use school records. A printed electronic school or medical record counts as an original for IRS purposes, which can save you from paying a foreign government for certified copies.3Internal Revenue Service. ITIN Supporting Documents
Translation Fees
Any document not in English needs a certified translation. Translators generally charge per word or per page. Expect roughly $25 to $100 per page for common languages, with rarer languages costing more. Multiple documents add up quickly.
Apostille Fees
Some applicants also need an apostille, a government-issued certificate confirming a document is authentic for international use. U.S. states charge roughly $3 to $26 per apostille. Foreign governments set their own fees.
Mailing Costs
If you’re mailing your application rather than submitting it in person, you’ll want proof of delivery. USPS Certified Mail costs $5.30 on top of regular postage.4United States Postal Service.

First-Class Mail Certified Mail with an electronic Return Receipt totals about $9 to $11, depending on envelope weight.
There’s a non-dollar cost worth counting too. If you mail originals rather than using a CAA or a Taxpayer Assistance Center, your documents are out of your hands until the IRS returns them. Processing typically takes seven weeks, and nine to eleven weeks during tax season (mid-January through the end of April) or when you apply from overseas.7Internal Revenue Service. Individual Taxpayer Identification Number (ITIN) Going without your passport for two or three months is a real price, even if it doesn’t appear on any invoice.
Renewal Costs Look Just Like Application Costs
An ITIN that isn’t used on a federal tax return for three consecutive years expires automatically on December 31 after that third year of non-use.8Internal Revenue Service. How to Renew an ITIN Renewal uses the same Form W-7, and the IRS still charges nothing. But you’ll face the same supporting-document and professional-assistance costs a second time.
One narrow break: if your expired ITIN only appears on information returns filed about you, such as a Form 1099 from a bank, you don’t need to renew it. The expired number still works for that third-party reporting.8Internal Revenue Service. How to Renew an ITIN
The Cost of Getting It Wrong
A rejected application is the most expensive outcome, because it means paying for documents, translations, and any professional help all over again, then waiting another seven to eleven weeks. If your application is incomplete, you’ll first get a CP566 notice asking for more information, with 45 days to respond.9Internal Revenue Service. Understanding Your CP566 Notice A formal rejection arrives as a CP567 notice; at that point, the IRS processes your tax return without an ITIN, and any refund you’re owed gets held until you reapply.10Internal Revenue Service. Understanding Your CP567 Notice
The most common reasons applications fail are missing or expired documents, forgetting to include the tax return, and submitting documents without a photograph or without support for foreign status. Getting the details right the first time is worth more than any shortcut.
The Cheapest Ways to Apply
The lowest-cost path is doing the paperwork yourself and taking it to an IRS Taxpayer Assistance Center that offers ITIN services. TAC appointments are free. Staff will review your form, authenticate most documents on the spot, return your originals before you leave, and mail the package for you.11Internal Revenue Service. IRS Taxpayer Assistance Centers with ITIN Services The catches: appointments can be hard to get in tax season, and not every location offers ITIN services.
A Volunteer Income Tax Assistance (VITA) site that offers ITIN services is the other free route. VITA uses volunteer Certifying Acceptance Agents who can authenticate documents and prepare your W-7 at no charge, and many sites will prepare your tax return for free if you qualify.12Internal Revenue Service. Volunteer Income Tax Assistance (VITA) Sites with ITIN Services Between free tax preparation and free document certification, a VITA appointment can bring your total out-of-pocket cost close to zero.
If you do hire a professional, shop around. Fees vary significantly even within the same city, and some preparers waive the W-7 fee entirely when you pay for return preparation.
What You’re Paying For
It’s worth being clear about what the ITIN itself does. It’s a tax-processing number. It doesn’t authorize you to work in the United States, doesn’t make you eligible for Social Security benefits, and doesn’t affect your immigration status.13Internal Revenue Service. Topic No. 857, Individual Taxpayer Identification Number (ITIN) The money you spend on the application buys you the ability to file a U.S. tax return, claim a refund you’re owed, or satisfy a reporting requirement — nothing more, and nothing less.
