How Long Does It Take to Get an ITIN? Real Timelines for Non-U.S. Residents
One of the most common questions non-U.S. residents ask is how long it takes to receive an ITIN. The answer depends on how the application is submitted and whether everything is prepared correctly.
At Nolly.com, we handle ITIN applications daily, and we know what affects processing times.
Average ITIN Processing Time
In most cases, the IRS takes six to ten weeks to process an ITIN application after receiving it.
During peak tax season, this timeline can be longer.
What Starts the Clock
The timeline begins when the IRS receives a complete application, not when you mail it.
Incomplete or incorrect applications restart the clock.
Common Reasons ITINs Take Longer
Processing delays often happen because of:
Missing signatures
Incorrect W-7 forms
Outdated documents
Unclear identification
Missing tax returns or supporting documents
Even small errors can cause weeks of delay.
Applying With a Tax Return
When an ITIN is submitted with a 1040NR tax return, processing often moves faster.
This is because the IRS clearly sees why the ITIN is needed.
Applications without clear supporting documents may be reviewed more slowly.
Applying Without Mailing a Passport
Mailing original passports often delays applications due to shipping time and processing holds.
Using a Certified Acceptance Agent allows identity verification without mailing original documents.
This reduces risk and often speeds up processing.
IRS Busy Seasons Matter
From February to May, IRS processing slows due to high volume.
Submitting applications outside peak season often results in faster approval.
What Happens After Approval
Once approved, the IRS sends a letter confirming your ITIN.
The ITIN can then be used to file tax returns, claim refunds, and meet U.S. tax obligations.
Why Some Applications Get Rejected
Rejections usually happen due to:
Incorrect exception categories
Expired identification
Mismatched information
Missing tax purpose
Reapplying after rejection adds months to the process.
