How Long Does It Take to Get an ITIN? A Clear Timeline for Non-U.S. Residents
- Many non-U.S. residents need an ITIN for filing a 1040NR tax return, receiving U.S. income, or completing real estate transactions. One of the most common questions people ask is, “How long does the ITIN process take?”
- At Nolly.com, we help clients worldwide apply correctly and avoid delays. Here is a simple and accurate timeline so you know what to expect.
Step 1: Preparing Your Application
The first part of the process involves gathering your documents. You will need:
- Form W-7
- A valid passport or identity documents
- A supporting tax document
Preparing everything correctly avoids long interruptions later.
Step 2: Submitting Through a Certified Acceptance Agent
Submitting your ITIN application through a Certified Acceptance Agent is the fastest method because:
- Your identity is verified without mailing your passport
- Your documents are reviewed for accuracy
- The application is submitted in the correct format
At Nolly.com, we complete this step on a video call, which saves time and prevents common mistakes.
Step 3: IRS Processing
Once the application reaches the IRS, the typical processing time is:
- 6 to 10 weeks during normal seasons
- 10 to 12 weeks during busy periods
- The IRS takes longer during tax season (February to May).
- If your application is missing information, the timeline can stretch much longer.
Step 4: Receiving the ITIN Letter
Once approved, the IRS sends an official letter with your ITIN. This letter arrives by mail.
If you applied through Nolly.com, we track your application and notify you as soon as the ITIN is issued.
What Causes Delays
Several issues can slow down processing:
- Incorrect or outdated W-7 forms
- Expired passports
- Blurry or incomplete document scans
- Missing tax documents
- Mismatched names or dates
- Mailing your passport instead of verifying it through a CAA
Most delays are avoidable with proper guidance.
How to Speed Up the Process
You can reduce wait time by:
- Preparing accurate documents
- Using a Certified Acceptance Agent
- Avoiding peak-season filing
- Checking all information before submission
At Nolly.com, we streamline your application to minimize processing time.
Why the ITIN Is Worth the Effort

- File U.S. tax returns
- Claim refunds
- Complete real estate sales
- Report investment income

An ITIN helps you remain fully compliant with U.S. tax laws.
