We Know Life in Two Tax Systems.

You Assumed Filing Did Not Apply to You

You assumed U.S. filing was something you left behind, or that it never applied to you at all.

The foreign accounts you hold may trigger an FBAR on top of the return.

You Fear Paying the IRS Twice

You already pay tax where you live and worry a U.S. return means paying on the same income again.

You are unsure whether the FEIE, the Foreign Tax Credit, or both settle it in your favor.

You Just Found Out You Have to File

A bank asked about FATCA, or an inheritance surfaced a U.S. filing duty you never knew you had.

You have never filed because no one told you to, and you are unsure what happens now.

You're Behind, or Weighing Renunciation

Years have gone unfiled, and you want a penalty-free way to get current without the drama.

You are considering renouncing and need the tax picture before an irreversible step.

Dual Citizen Tax Resources

Greenback maintains a comprehensive library of guides covering nearly every tax topic a dual citizen faces. Here are the resources our clients reach for most.

Why Dual Citizens Still File a U.S. Return

The U.S. taxes citizens on worldwide income no matter where they live, so dual citizens still file, but the Foreign Earned Income Exclusion and Foreign Tax Credit usually erase the U.S. bill. Our guide to dual citizen taxes covers who must file and the exceptions.

How the FEIE and Foreign Tax Credit Work Together

Two tools keep most dual citizens from paying twice: the FEIE excludes earned income from U.S. tax, and the Foreign Tax Credit reduces your U.S. tax by the foreign tax you already paid. In high-tax countries the credit often erases the bill. Our FEIE vs. Foreign Tax Credit guide shows which fits you.

What to Do If You Only Just Found Out

Many dual citizens learn of their U.S. filing duty through a FATCA bank question, an inheritance, or a big transaction. If you never filed because you did not know, there are penalty-free paths back. Our guide to Accidental American taxes explains how compliance works when the rules take you by surprise.

Reporting the Accounts Where You Live

The everyday checking, savings, and retirement accounts you hold in your other country can require reporting once they top $10,000 combined at any point in the year. Our guide to FBAR vs. Form 8938 explains which accounts count, the thresholds, and how the two reports differ.

How Streamlined Filing Clears Missed Years

If your late filing was non-willful, the IRS Streamlined Filing Procedures let you get current with three years of returns and six years of FBARs, usually with no penalties. Most dual citizens owe little or nothing after credits. Our guide to Streamlined Filing walks through who qualifies and each step.

Why the U.S. Taxes You No Matter Where You Live

Citizenship-based taxation means the U.S. taxes its citizens on worldwide income by citizenship, not residence, which is why filing continues even after decades abroad. Filing rarely means owing, though. Our guide to U.S. taxes for citizens abroad explains the rule and the credits that bring most bills to zero.

Dual Citizen Tax FAQs

 Get answers to the questions dual citizens ask most, from double taxation to catching up after years away.

 Usually not on the same income. Dual citizens must file a U.S. return on worldwide income, but the Foreign Tax Credit and the Foreign Earned Income Exclusion (up to $130,000 for the 2025 tax year) offset most or all of the overlap.

You file in the U.S. to claim those benefits; if you already pay tax where you live, the credit usually erases the U.S. bill, especially in higher-tax countries.

Yes. Many dual citizens learn of the U.S. filing duty years or decades late, through a FATCA bank question, an inheritance, or a big transaction. The IRS Streamlined Filing Procedures are built for exactly that: three years of returns and six years of FBARs, plus Form 14653, the statement you sign explaining why you did not file.

The package is a flat $1,750. Most owe little or nothing after the Foreign Tax Credit, and getting current is more manageable than most people expect.

Yes. If the everyday checking, savings, and retirement accounts you hold where you live exceed $10,000 combined at any point in the year, an FBAR (FinCEN Form 114) is due and must be filed separately from your return.

We determine which accounts count, calculate the aggregate threshold, and e-file it. FBAR is a flat $125 for up to five accounts, with each additional block of five at $60. If you are behind on past FBARs, we help you catch up, too.

Yes. The decision to renounce is personal, but we handle the tax side. We help you file five years of compliant returns and Form 8854 so you are not treated as a covered expatriate, and we explain the exit tax under Section 877A if it could apply to you.

A consultation at $250+ walks through the full financial picture before you take an irreversible step, so you decide with the numbers in front of you.

Pricing is flat-fee and published up front. A federal return is a flat $565, FBAR is $125 for up to five accounts, Form 8938 is $120 for up to five accounts plus $65 for each additional five, the Streamlined catch-up package is $1,750, and state returns are $185.

UK Self Assessment is $910 and is billed separately from the U.S. return, and consultations start at $250. You see your full cost before any work begins.
