Your ITIN is "activated" the moment the IRS assigns it to you and sends you a CP-565 notice. There is no further action you need to take to "activate" it. The process of obtaining an ITIN is how it becomes active for tax purposes. The IRS issues an ITIN to individuals who need a U.S. taxpayer identification number but do not have and are not eligible for a Social Security number (SSN). This includes non-resident aliens filing U.S. tax returns, resident aliens filing U.S. tax returns, and certain other non-U.S. persons. The question of how to activate ITIN number is best understood by comprehending the ITIN issuance process itself. Once issued, the ITIN is your permanent tax identification number for all U.S. federal tax purposes.
Understanding the ITIN Issuance Process
The IRS assigns an ITIN when you file a U.S. federal tax return or when you are required to have a U.S. taxpayer identification number for other tax purposes, such as applying for an EIN (Employer Identification Number) for a business, or for certain international tax filings.
When is an ITIN Required?
Individuals typically require an ITIN in the following situations:
- Non-resident aliens filing a U.S. tax return: If you are not a U.S. resident and have U.S. source income that requires you to file a U.S. tax return (e.g., Form 1040-NR), you will need an ITIN.
- U.S. resident aliens filing a U.S. tax return: If you are a resident alien for tax purposes but do not qualify for an SSN, you will need an ITIN.
- Dependents or claiming dependents: Non-resident alien dependents or individuals claimed as dependents on a U.S. tax return may require an ITIN.
- U.S. business owners: If you are a non-U.S. person owning a U.S. LLC or other business entity and need to file specific informational returns like Form 5472, you will need an ITIN. This is common for foreign owners of single-member U.S. LLCs. If you are establishing a U.S. business, you will also likely need an EIN, which can sometimes be obtained by foreign individuals without an SSN or ITIN, but an ITIN can be useful in other related tax filings.
- Applying for a U.S. bank account: While not all banks require an ITIN for non-residents to open an account, some may, especially for business accounts. Many foreign nationals find they can open U.S. bank accounts with just their passport and foreign tax ID, but an ITIN can sometimes facilitate the process, particularly if you are forming a U.S. entity. Services like Mercury, Relay, or Brex often have specific requirements for non-resident founders.
The ITIN Application Process
To obtain an ITIN, you must file Form W-7, Application for IRS Individual Taxpayer Identification Number. This form must be submitted with your U.S. federal income tax return for the year you are claiming the ITIN, unless you qualify for an exception. You can also apply for an ITIN without filing a tax return if you meet certain criteria (e.g., you are a dependent, a student, or applying for an EIN on behalf of a U.S. business).
When you submit Form W-7, you must include original documentation or certified copies of documents proving your identity and foreign status. Acceptable documents include:
- Passport (most common and recommended)
- National identity card
- U.S. driver's license
- Birth certificate (for dependents under 18)
- Foreign driver's license
- Foreign voter's registration card
- Civilan I.D. card (from your country of residence)
- Visa
- U.S. state identification card
Submission Methods for Form W-7
There are three primary ways to submit your Form W-7 application:
- Mail to the IRS: You can mail your completed Form W-7, your original tax return, and your supporting identification documents to the IRS address listed in the Form W-7 instructions. The IRS will review your application and documents. They will mail your original documents back to you after processing, which can take several weeks.
- Through a Certified Acceptance Agent (CAA): This is often the most convenient method. CAAs are individuals or entities authorized by the IRS to help taxpayers apply for ITINs. They can verify your original identification documents and forward your Form W-7 application and supporting documents to the IRS on your behalf. This means you do not have to mail your original passport or other vital documents. The CAA will return your original documents to you immediately after verification. itin.net works with a network of CAAs to streamline this process for our clients.
- At an IRS Taxpayer Assistance Center (TAC): Some IRS TACs offer ITIN application services by appointment. You will need to bring your Form W-7, tax return, and original identification documents. However, not all TACs provide this service, and appointments can be difficult to secure.
The "Activation" Moment: Receiving Your ITIN
Once the IRS processes your Form W-7 application and accompanying tax return (or other required documentation), they will assign you an ITIN. You will receive an official notice from the IRS, Letter CP-565, Individual Taxpayer Identification Number Assignment, which contains your unique ITIN. This letter is the official confirmation that your ITIN has been issued and "activated" for tax purposes.
There is no separate step or form required from you to "activate" the ITIN after receiving CP-565. It is immediately ready for use on any future tax filings, for claiming benefits, or for any other purpose for which a U.S. taxpayer identification number is required.
Processing Times and Costs
Processing Time:
The IRS processing times for Form W-7 can vary significantly. Historically, it has taken anywhere from 7 to 11 weeks for the IRS to process an ITIN application when submitted directly by mail. If you apply through a CAA, the application is forwarded to the IRS, and the processing time generally remains the same for the IRS's part. However, the benefit of using a CAA is that you do not have to mail your original documents, and the CAA can often pre-check your application for accuracy, potentially reducing delays.
During peak tax seasons (typically January through April) or when IRS resources are strained, processing times can be longer. It is advisable to apply well in advance of any tax deadlines.
Costs:
- IRS Fee: The IRS does not charge a fee to apply for an ITIN. The application for Form W-7 is free.
- CAA Fees: If you choose to use a Certified Acceptance Agent (CAA), the agent may charge a service fee for their assistance. These fees vary by CAA and can range from $50 to over $200, depending on the complexity of the application and the services provided. The fee is for the agent's time and expertise in verifying your documents and submitting your application, not for the ITIN itself.
- Document Certification Fees: If you choose to obtain certified copies of your documents from your country of origin (e.g., from the issuing agency), there may be fees associated with that process.
What Happens After You Receive Your ITIN?
Once you have your ITIN and the CP-565 notice, it is active and ready for use. The primary use for most individuals is filing U.S. tax returns. For example, if you are a foreign owner of a U.S. LLC, you will use your ITIN to file Form 5472 and your Form 1120 (if applicable) to report certain transactions with related parties. The deadline for these forms is typically April 15th for the preceding tax year, or October 15th if an extension is filed.
ITIN Renewal
ITINs that are not used on a federal tax return for three consecutive tax years are considered invalid by the IRS and will expire. Additionally, the IRS periodically requires ITINs to be renewed, particularly those with middle digits between 70 and 82 (e.g., 9XX-70-XXXX). If your ITIN has expired or is nearing expiration, you must renew it by filing Form W-7 again, along with a U.S. federal tax return, and providing updated identification documents. The renewal process is similar to the initial application.
Future Tax Filings
Your ITIN is your permanent identifier for U.S. tax purposes. You must use it on all future U.S. federal tax returns you file. If you later become eligible for and obtain a Social Security number (SSN), you must notify the IRS. Your ITIN will then be deactivated, and you will use your SSN for all future tax filings. You cannot have both an ITIN and an SSN simultaneously for tax filing purposes.
Common Mistakes to Avoid
When applying for an ITIN, several common mistakes can lead to delays or rejections:
- Incomplete Form W-7: Ensure all sections of the form are filled out accurately and completely. Missing information is a primary cause of delays.
- Incorrect or Missing Tax Return: If you are applying for an ITIN based on a tax return, ensure the tax return is properly completed and filed simultaneously with Form W-7, or that you meet an exception allowing you to apply without one.
- Invalid Identification Documents: Using expired documents or documents that are not on the IRS-approved list can cause your application to be rejected. Ensure your passport is valid and meets the IRS criteria. If you are submitting certified copies, ensure they are properly certified by the issuing agency or a CAA.
- Not Submitting Original or Certified Documents: If you mail your application directly to the IRS, you must send original documents or certified copies from the issuing agency. If you use a CAA, they will verify your original documents.
- Forgetting to Sign and Date: Form W-7 must be signed and dated by the applicant.
- Not Providing a Social Security Number (if applicable): If you have applied for an SSN but have not yet received it, you must still provide that information on Form W-7. If you are eligible for an SSN, you should apply for one instead of an ITIN.
When to Seek Professional Help
While the Form W-7 process is designed to be accessible, certain situations warrant professional assistance. If you are dealing with complex international tax matters, have unique business ownership structures, or are unsure about your U.S. tax obligations, consulting with a qualified tax professional or an experienced Certified Acceptance Agent is highly recommended. They can help ensure your application is accurate, complete, and submitted correctly the first time, saving you time and potential frustration.

The "activation" of an ITIN is solely the IRS's action of issuing it to you. Your role is to correctly apply for it. Once issued, it is active for all U.S. tax purposes. Understanding the nuances of the ITIN application is key to successfully obtaining and using your number. If you are unsure about any part of the process, seeking guidance from a tax professional or a CAA is the most prudent step.
