US taxes while living abroad
Do tax treaties, foreign pensions and state taxes change what you owe abroad?
Last reviewed .
They can, but less than many people expect. Publication 54 explains that treaty benefits are specific and that a saving clause usually preserves US taxation of its citizens. A foreign pension's local tax-favored label does not set its US treatment. State filing duties come from state law, not federal law. A licensed tax professional should apply these rules to your own facts.

Does a tax treaty mean an American abroad stops filing US taxes?
Rarely. Most US income tax treaties contain a saving clause that lets the US tax its citizens as if the treaty did not exist, with listed exceptions. Publication 54 explains that treaty benefits are specific. Confirm the treaty in force, any protocol, its effective date and the exact article before relying on it. Claiming a treaty position can require a disclosure on the return.
How are foreign pensions treated for US tax?
There is no single answer. A foreign country's label for a tax-favored account does not establish its US treatment. Social security benefits, employer pensions, private retirement accounts and investment wrappers can each be treated differently, and a treaty article may change the result for some of them. Analyze each plan with its documents.
Do you still owe state tax after leaving the US?
It depends on the state. No federal income tax does not mean no state filing duty. Each state has its own residency and domicile rules, and some look at ties such as a home, a driver's license or voter registration. Use the state revenue department's own guidance.
What changes when you move back to the US?
Returning changes residence, work location and travel-day facts. It can end a qualifying period for the exclusion and change which state taxes you. Keep the timeline of the move instead of copying last year's settings into a new return.
Checklist before you start
- Identify the treaty between the US and your country, with any protocol.
- Note the treaty article you think applies and why.
- Collect plan documents and annual statements for each foreign pension.
- List your remaining ties to your last US state.
- Find the state revenue department's guidance on part-year and nonresidents.
- Record the dates of any move into or out of the US.
Common questions
What is a saving clause?
A treaty provision that generally lets the US tax its citizens as if the treaty did not apply, apart from the exceptions it lists.
Is my foreign pension tax-free in the US?
Not automatically. Its US treatment depends on the plan type and any treaty article. A preparer should review the plan documents.
Do I have to file a state return if I live abroad?
Possibly. It depends on the state's residency and domicile rules, which come from state law.
