Leaving the country does not end the filing.
The US taxes citizens and green card holders on worldwide income wherever they live. Double taxation is relieved two different ways, and which one leaves you better off depends almost entirely on the tax rate in the country you moved to.
Foreign earned income exclusion
Removes a band of foreign salary from US tax altogether, provided you meet a residence or physical presence test. Strongest where local tax is low or nil, because there is little foreign tax to credit instead.
Foreign tax credit
Credits the tax you already paid abroad against your US liability. Stronger in high-tax countries, and it reaches investment and other income that the exclusion cannot touch.
Citizenship follows you. So does the return
Four things expatriates most often find out too late.
Three stages, followed down both sides
Qualifying comes first, because it constrains what is available. The annual filing is where the choice is made. Accounts and assets run alongside both, independently of either.
Qualifying
You must satisfy a residence or physical presence test, and your tax home has to be abroad. Days spent back in the US are counted, so travel patterns matter.
No presence test to meet. What matters is foreign tax actually paid or accrued, and whether it lands in the same category as the income it is credited against.
The annual filing
Claimed on the return each year. It covers earned income only, so salary is sheltered while investment income and gains remain fully exposed.
Computed by category against the US tax on the same income. Unused credit can often be carried to other years rather than simply lost.
Accounts and assets
Reporting is unaffected by the route you choose. Excluding income from tax does not exclude the accounts holding it from disclosure.
Equally unaffected. Foreign account and asset reporting runs on its own rules, whatever your relief position looks like.
Quiet years are the expensive ones
Relief usually eliminates the tax while leaving the filing obligation entirely intact.
A separate filing on its own rules, with penalties that do not depend on any tax being owed.
Moving countries or changing income mix can flip which relief is better, sometimes substantially.
Your old state can keep taxing you for years after you left if the link was never properly cut.
What expatriates ask first
I pay tax where I live. Do I really still file in the US?
Yes. The US taxes on citizenship rather than residence, so the return is due wherever you live. What paying tax abroad usually does is remove the US liability through the exclusion or the credit — but that relief is claimed on a return, so the filing itself does not go away.
Which is better, the exclusion or the credit?
It depends on your numbers. Broadly, the exclusion tends to suit low-tax countries and salary income, while the credit tends to suit high-tax countries and reaches income the exclusion cannot cover. We model both rather than assuming, because the gap between them is often larger than people expect.
I have not filed since I moved. How bad is it?
Usually more fixable than people fear, particularly where no US tax was actually owed. There are established routes back into compliance and the right one depends on why the years were missed. Do not start filing back years on your own before that is settled.
How is this priced?
A fixed fee, scoped from where you live, your income sources and whether catch-up years are involved. Quoted in writing before any work begins, and never billed by the hour.
