Free US expat tax tools
Quick, free tools to help you understand your US tax position as an American abroad. They give directional guidance, not tax advice, and they never file anything. When you want exact numbers, a CPA or Enrolled Agent can take it from there.

Why we built these
Most expat tax software hides useful answers behind a paywall, so a question as basic as "should I use the FEIE or the FTC?" often means paying first. These tools are free and need no sign-up. They are educational estimates: the real filing, with the interactions between credits, treaties, pensions, and state tax, is work for a qualified preparer.
Does the US tax side apply to you?
Quick check: are you a US citizen or green card holder using this for a US tax filing?
Are you up to date on your US tax returns and FBARs?
No problem. The tool is free to use either way, with no US filing questions attached.
Good. When filing season comes, the licensed CPAs and Enrolled Agents at Capital Tax Limited prepare US expat returns start to finish.
Catching up has a defined IRS route, the Streamlined Filing Compliance Procedures. The licensed CPAs and Enrolled Agents at Capital Tax Limited handle these filings for Americans abroad, and the first step is a short message describing where you stand.
