Frequently Asked Questions
Do I really have to file U.S. taxes if I live abroad?
Yes. U.S. citizens and Green Card holders must file annual tax returns no matter where they live or earn income. Even if you pay taxes abroad, you’re still required to report your worldwide income to the IRS. Fortunately, tools like the Foreign Earned Income Exclusion and Foreign Tax Credit often eliminate or reduce your U.S. tax liability.
What documents do I need to get started?
We keep it simple. Once you register, you’ll complete a Smart Tax Organizer tailored to your situation. Most clients upload their income documents (like W-2s or foreign payslips), prior-year returns (if available), and bank or investment statements if required. We guide you every step of the way.
I’m behind on my U.S. taxes—what should I do?
Don’t panic. If you qualify, the IRS Streamlined Filing Compliance Procedures allow you to catch up on past returns without penalties. We specialize in helping expats file safely and efficiently—even if it’s been years.
How long does the process take?
Most returns are completed within 10–15 business days once all documents are received. If you’re on a tight deadline, just let us know—we offer expedited options when needed and always communicate your review timeline upfront.
