Expat Tax Tools

Free calculators and tools to help you understand your US tax obligations as an American living abroad.

Choose by situation

Start with the question you need answered

These tools organize facts and point to the next review step. They do not determine eligibility, filing obligations, or a filing position for you.

I have foreign bank or investment accounts.

You need to organize account ownership, maximum values, and filing years before deciding what applies.

Check the account facts

I am behind on U.S. filings.

You have missed returns or foreign-account reports and need a facts-first procedure review.

Explore catch-up questions

I earned income outside the United States.

You want to compare the questions behind FEIE, foreign tax credit, and broader return scope.

Review the planning tools

I still have ties to a U.S. state.

Domicile, property, voter registration, and other facts may change the state-filing analysis.

Map the state facts
Primary sources control current rules. Start with the IRS guidance for Americans abroad, the IRS Form 8938 comparison, and FinCEN's FBAR instructions before acting on a result.

Free resources

Keep the decision path moving

Save or share a practical checklist after you use a tool. Each resource explains what to gather and when a fact-specific review is worthwhile.
