TaxCurb: U.S. tax filing for F-1 international students

Taxes are complicated enough. The software should not be.

Most tax products begin with assumptions that do not fit international students. TaxCurb begins with the details that make your return different.

• Made for international students. Your visa, U.S. travel history, school, and income are part of the flow from the beginning.
• Questions you can actually answer. Each step explains what we need and why, without dropping you into an IRS form.
• A return that stays organized. Keep your information, documents, forms, and progress together in one place.

One clear next step, all the way through.

You answer straightforward questions. TaxCurb organizes the details and helps you prepare the right forms for review.

• Tell us about your year. Share your visa, travel, school, and income information.
• Work through your return. Complete each section with context where you need it.
• Review with confidence. Check your information and understand what comes next.

Your filing essentials, in one guided process.
