Applying for an ITIN should be simple, but many applications get delayed by the IRS because of avoidable mistakes. These delays can last weeks or even months, which creates stress for people who need their ITIN for a 1040NR tax return, FIRPTA refund, or banking and investment purposes.
At Nolly.com, we handle ITIN applications for clients worldwide and help them avoid the errors that slow down processing. Here’s what you need to know to prevent delays.
Missing or Incorrect Identification
The most common reason the IRS delays an ITIN application is missing or incorrect identity documents. Your passport is usually the best option because it proves both identity and foreign status.
Common issues include:
-
Expired passports
-
Blurry photos
-
Damaged documents
-
Names that don’t match the W-7 form
Before submitting, make sure your documents are clear, valid, and match your application exactly.
Not Including a Tax Document
The IRS requires a supporting tax document with every ITIN application. This proves you have a valid reason for needing an ITIN. Examples include:
-
A 1040NR tax return
-
A FIRPTA withholding form (8288-A or 8288-B)
-
A letter from a U.S. withholding agent
If you forget this step, the IRS will pause your application until you submit the missing paperwork.
Submitting an Outdated Form
The IRS updates Form W-7 over time. Using an old version is a common cause of delay. Make sure you’re using the most recent Form W-7 available.
At Nolly.com, we always use the latest IRS-approved version to avoid rejection.
Errors on Form W-7
Small mistakes can create big delays. Common errors include:
-
Leaving blank spaces
-
Checking the wrong reason box
-
Incorrect dates or birth information
-
Missing signatures
The IRS will not process the application until these details are corrected.
Mailing Original Passports
If you apply to the IRS directly, you must mail your original passport or visit an IRS office. This is one of the biggest sources of delay because:
-
Mailed passports get held for weeks
-
Many get lost or delayed in transit
-
Processing slows when identity cannot be verified
With Nolly.com, you never mail your original passport. As IRS Certified Acceptance Agents, we verify your identity digitally and securely, which speeds up processing.
Incomplete Applications
Many applications are delayed simply because the IRS needs more information. This can happen if your reason for applying isn’t clear or if something in your application triggers extra review.
Our team reviews your entire file to ensure everything is complete before submission.
