- Selling U.S. property as a non-U.S. resident comes with tax obligations. Many sellers are surprised to learn they need an ITIN to complete the process properly.
- At Nolly.com, we help international sellers understand the steps and avoid delays.
Why an ITIN Is Required After a Sale
- When a non-U.S. resident sells U.S. property, FIRPTA rules apply.
- Tax is often withheld at the time of sale.
An ITIN is required to file a U.S. tax return and reconcile the actual tax owed.
FIRPTA Withholding Is Not Final Tax
- The amount withheld is an estimate.
- The actual tax may be lower.
Filing a return allows sellers to claim a refund if too much was withheld.
When to Apply for an ITIN
- Most sellers apply for an ITIN after the sale.
- The ITIN application is usually submitted with the 1040NR tax return.
This shows the IRS the clear tax purpose.
Documents Needed
Common documents include:
- A valid passport
- Property sale documents
- FIRPTA withholding forms
- The completed tax return
Accurate documents prevent delays.
Common Mistakes to Avoid
- Applying without a tax return
- Using incorrect FIRPTA forms
- Missing signatures
- Using outdated IRS forms
These mistakes often delay refunds.
Why Timing Matters
- Refunds cannot be issued without an ITIN.
- Delays in applying delay refunds.
Applying as soon as possible helps speed things up.
Using a Certified Acceptance Agent
- Mailing original passports carries risk.
- A Certified Acceptance Agent verifies documents securely without mailing originals.
This often speeds up approval.
