About itin.so

We are an IRS-authorized ITIN application service built for non-US residents who need a US tax identification number. Our mission is simple: make the ITIN process fast, affordable, and stress-free.

What We Do

itin.so prepares complete ITIN applications for non-US residents worldwide. We handle the W-7 form preparation, document review, and IRS submission so you don't have to navigate the process alone. Whether you are an Amazon seller in Germany, a freelancer in India, a real estate investor in Brazil, or a student in Canada, we have helped people in your situation get their ITIN.

Our Standard service ($197) prepares your application in 7-10 business days. Our Express service ($297) gets it done in 2-3 business days with priority handling and a money-back guarantee.

IRS-Authorized Partner

We work with IRS-authorized partners to prepare and submit your ITIN application. This means you do not need to mail your original passport to the IRS. We review and certify your identity documents on your behalf. Your passport stays with you throughout the entire process.

Our authorization can be verified through the IRS Acceptance Agent directory.

Why We Built itin.so

Getting an ITIN should not cost $300-$400 or take weeks of back-and-forth. We saw non-US residents struggling with confusing IRS forms, expensive services, and long wait times. So we built a service that is faster and more affordable than any competitor, without cutting corners on quality or accuracy.
