Foreign Pensions for US Expats: Reporting, Taxation, and Treaty Benefits

Foreign pensions are simultaneously one of the most important and most misunderstood aspects of US expat tax compliance. Whether you are a retiree drawing from a UK SIPP, a professional contributing to Australian superannuation, or a dual citizen with a Canadian RRSP, the US tax treatment of your foreign pension can differ dramatically from your host country's treatment — and the penalties for getting it wrong are severe.

This guide covers the major foreign pension types, how the US taxes them, what forms you must file, and how tax treaties affect the outcome.

A foreign pension can be a statutory social-insurance benefit, government-service pension, employer plan, personal account, compensatory trust, annuity or insurance contract, or another arrangement. The local name is the start of the fact review, not the U.S. answer. Start with the plan, participant, and year. Record the plan name, country, sponsor, governing law, administrator, participant and beneficiary, and the years in which U.S. citizenship or residency applied. Then identify mandatory and voluntary employee, employer, and government contributions; vesting and access rights; transfers; distributions; and the documents that support each fact. Keep four analyses separate. Income analysis determines how contributions, current earnings, and distributions fit U.S. domestic law, prior inclusions, and cost. Treaty analysis reads the actual treaty, protocol, technical explanation, residence article, pension or government-service article, lump-sum provision, and saving clause. Information-reporting analysis separately tests Form 8938, FBAR, and any genuine foreign-trust question. Investment analysis determines direct or indirect shareholder status and any treaty-pension exception before treating pooled holdings as participant-level PFIC reporting. One channel does not decide the others. Check current trust-reporting exceptions before selecting a form. Current Form 3520 instructions list exceptions for qualifying Canadian retirement plans under Rev. Proc. 2014-55, qualifying tax-favored foreign trusts and eligible individuals under Rev. Proc. 2020-17, and arrangements meeting the May 2024 proposed-regulation reliance rule. The plan and taxpayer must satisfy the actual conditions. Do not file "protectively" merely because a product is called a pension. For an eligible individual with a qualifying RRSP or RRIF, Rev. Proc. 2014-55 expressly removes Forms 8891, 3520, and 3520-A reporting; other income and asset/account reporting remain separate. Product names are intake clues. A SIPP, workplace pension, superannuation fund, RRSP/RRIF, provident fund, personal pension, government benefit, retirement annuity, and insurance-based plan can present different legal and economic facts. Do not use a blanket trust, social-security, treaty, PFIC, or annual-income conclusion for an entire category. Before a contribution, transfer, or distribution. Preserve the plan rules, contribution and vesting history, annual values, prior U.S. treatment, transaction notice, original-currency amounts, foreign tax, investment menu, treaty sources, and prior U.S. forms. A local tax-free rollover or lump sum is not automatically tax-free in the United States.
