Many residents of Mexico earn income connected to the United States. This can include rental income, investment income, or online business revenue. If you are not eligible for a Social Security Number, you may need an ITIN.
At Nolly.com, we help Mexico residents apply for an IRS ITIN number correctly and efficiently.
When an ITIN Is Required
- You may need an ITIN if you must file a U.S. tax return and do not qualify for an SSN.
- Common situations include:
- Rental property in the United States
- U.S. investment income
- FIRPTA property sales
- U.S. casino winnings
In these cases, Form 1040NR is usually required.
Withholding Does Not Replace Filing
- Some U.S. payers withhold tax automatically.
- This does not remove the need to file a return.
Filing may reduce tax owed or allow a refund.
How the ITIN Application Works
- The ITIN application uses Form W-7.
- It is normally submitted together with a U.S. tax return.
A valid passport is typically sufficient for identity verification.
Common Mistakes to Avoid
- Submitting incomplete forms
- Using outdated IRS versions
- Failing to include the tax return
- Sending unclear identification documents
These mistakes cause delays.
Processing Time
- ITIN processing usually takes six to ten weeks.
- During peak season, it may take longer.
Applying correctly the first time reduces delays.
Why Professional Preparation Helps
- Incorrect filings may trigger IRS letters or rejections.
- Accurate preparation protects refunds and reduces stress.
