Individual Taxpayer Identification Number (ITIN) Applications

icons8-chat

Applying for an ITIN (Individual Taxpayer Identification Number) is essential for non-residents who need to file US tax returns but are not eligible for a US social security number (SSN). Our certified acceptance agents (CAA) are authorised to help you with every step of your ITIN number application, ensuring secure certification of your identity and documents so that you do not need to send originals to the IRS.

 

Why Apply for an ITIN Number?

You may need to apply for an ITIN if you:

  • Are a non-resident with US rental income

  • Need a US tax identification number for partnership income, property sales, or business dealings

  • Have worked in the US briefly and did not receive an SSN

  • Are the spouse or dependent of a US citizen or resident

  • Need to comply with US tax return filing requirements as a non-resident

How to Get an ITIN Number

Our CAAs will guide you through the application process, including:

  • Booking an in-person or remote appointment

  • Certifying identity documents and completing your W7 form

  • Submitting an accurate ITIN application to minimise risk of rejection and delays.

  • Providing expert support from initial application, through IRS processing, to ITIN number receipt

Certified Acceptance Agent Support

As certified acceptance agents, we:

  • Check and certify your passport or birth certificate

  • Support you in completing W7 forms for your ITIN application or renewal
