The Most Common Reasons ITIN Applications Get Delayed (And How to Avoid Them)
Applying for an ITIN can feel simple, but many applications get delayed because of preventable mistakes. These delays can last months, especially during busy IRS periods. At Nolly.com, we help clients avoid these issues by preparing complete, accurate applications.
Here are the most common reasons ITIN applications get delayed and how to avoid them.
Missing or Incorrect Identification
The IRS must verify who you are. If your identification is unclear or incorrect, your application will be delayed.
Common issues include:
-
Expired passports
-
Blurry photocopies
-
Names that don’t match the W-7 form
-
Missing birth information
-
Damaged documents
Your passport should be current, readable, and consistent with all other forms.
Missing Supporting Tax Document
An ITIN cannot be issued unless you provide a valid tax document that explains your need for the number. Examples include:
-
A 1040NR tax return
-
FIRPTA documents for a real estate sale
-
A letter from a withholding agent
-
A financial document requiring an ITIN
If this document is missing, the IRS will hold your application.
Using an Outdated W-7 Form
Many applicants download old versions of the W-7 form online. The IRS rejects outdated forms.
At Nolly.com, we always use the latest approved version.
Errors on the W-7 Form
Even small errors cause delays. Examples include:
-
Wrong reason box selected
-
Missing signatures
-
Incorrect dates
-
Mismatched information
-
Blank fields
The IRS does not process incomplete forms.
Mailing Original Passports
If you apply by yourself, you must mail your original passport to the IRS.
This often leads to:
-
Long postal delays
-
Lost documents
-
Application holds
-
Stress and travel problems
When you apply through Nolly.com, you keep your passport. We verify your identity digitally as Certified Acceptance Agents.
Incomplete Foreign Status Documentation
The IRS must confirm that you are a non-U.S. resident. If anything is unclear, the application is paused. A valid passport usually satisfies this requirement, but only if submitted correctly.
Busy Filing Seasons
During tax season, IRS processing slows down. Filing early or using a fast submission method helps reduce wait times.
