Foreign Pensions and US Tax: UK, Canada, Germany

Millions of Americans worked abroad before returning to the US, and millions of foreign nationals became US citizens without fully understanding what the IRS does with their foreign pension benefits. The answer is rarely simple. The UK state pension is fully taxable in the US as ordinary income, yet many UK expats report it nowhere on their US return. The Canadian RRSP gets automatic tax deferral under a treaty election that most holders don't know exists. The German statutory pension is fully taxable in the US even when Germany doesn't tax it at all. Each country's pension system interacts differently with the US Internal Revenue Code, and the mistakes—back taxes, missed credits, unfiled reporting forms—are expensive.

This guide covers the three most common cases for US expats: UK, Canada, and Germany. If your foreign pension is from another country, the same framework applies—check the relevant US tax treaty, determine whether the saving clause limits treaty benefits, and identify which reporting forms apply to your account type.

Why Foreign Pensions Create US Tax Complexity

US citizens and green card holders owe US taxes on worldwide income. That includes pension income from foreign sources. Unlike US-qualified plans (401(k), IRA, pension from a US employer), most foreign pension arrangements do not qualify as "qualified plans" under the US Internal Revenue Code. This creates four distinct problems:

1. No automatic deferral: Employer contributions to some foreign plans may be includable in US gross income in the year made, even though the money is locked up in the foreign country for decades.
2. PFIC risk on underlying investments: Foreign pension funds that hold non-US mutual funds or pooled investments can trigger passive foreign investment company (PFIC) rules, creating punitive US tax treatment on gains. The PFIC guide covers election options in detail.
3. Reporting obligation independent of tax: Foreign pension accounts must be reported on FBAR and Form 8938 regardless of whether any US tax is owed, with serious penalties for missed filings.
4. Double taxation risk: If the foreign country also taxes the pension—common for US citizens resident in the country where they earned the pension—both tax systems apply simultaneously. The Foreign Tax Credit on Form 1116 reduces but may not eliminate double taxation.

Tax treaties mitigate some of these problems. The US has tax treaties with over 65 countries, and most include a pension article. But the "saving clause" in nearly every US tax treaty allows the US to tax its own citizens regardless of the treaty's terms—meaning US citizens cannot use a treaty to fully escape US taxation even when the treaty text seems to say they can.

UK Pensions: State, SIPP, and Workplace Plans

The UK has three primary pension types relevant to US expats: the UK state pension, employer workplace pensions (defined benefit and defined contribution), and the Self-Invested Personal Pension (SIPP).

UK State Pension

The full UK new state pension for 2025/26 is £230.25 per week (approximately $15,200 per year at the 2025 average exchange rate). It is taxable in the UK for UK residents once total income exceeds the personal allowance (£12,570). For non-UK residents, HMRC generally does not tax the UK state pension.

For US purposes, the UK state pension is fully taxable as ordinary income on your US return. It is reported on Schedule 1, line 8, with a description such as "UK State Pension." The US-UK tax treaty (Article 17) allows both countries to tax pension income, but the saving clause preserves the US's right to tax US citizens regardless of the treaty. If you paid UK income tax on the pension (because you're a UK resident), you claim a Foreign Tax Credit on Form 1116 to offset the US tax on the same income.

UK Workplace Pensions and SIPPs

UK employer pension contributions made on your behalf are generally excludable from US gross income during the accumulation phase under a reasonable reading of the US-UK treaty (Article 18(5) covers UK occupational pension schemes). Contributions you make personally are not deductible in the US the way a 401(k) or IRA contribution would be.

During accumulation, investment income and gains inside the pension typically grow without current US tax because most practitioners treat them as deferred under the treaty. This is an area where professional guidance matters: the treaty language is ambiguous and practitioner interpretations differ.

Upon distribution, UK workplace pension and SIPP payments are taxable in the US as ordinary income, with a Foreign Tax Credit available for any UK income tax paid on the same distributions. Report the gross amount, then claim the credit on Form 1116 to prevent double taxation.

Canadian RRSP and RRIF: The Auto-Deferred Exception

Canada's Registered Retirement Savings Plan (RRSP) is the closest foreign equivalent to a US traditional IRA. It has favorable treaty treatment under the US-Canada Income Tax Convention (Article XVIII(7)), making it the most straightforward foreign pension arrangement for US expats.

Automatic Tax Deferral Since 2014

Since the IRS issued Revenue Procedure 2014-55, US persons with RRSPs and RRIFs automatically receive US tax deferral on the income accruing inside the account. The old Form 8891 (which required an annual election for deferral) was eliminated. No special form or annual election is currently required to preserve RRSP deferral—you simply report distributions when made.

This is a significant advantage over most foreign pension arrangements. Your RRSP grows without current US tax on the investment income and gains inside the account, mirroring the treatment of a US traditional IRA. Employer contributions to a RRSP are also generally deferred from US gross income until distributed.

Distributions and Canadian Withholding

When you withdraw from an RRSP or RRIF, the full distribution is taxable in the US as ordinary income. Canada withholds tax at source on distributions to non-residents:

Distribution Type	Canadian Withholding Rate	US Treatment
RRSP lump sum withdrawal (non-resident)	25%	Fully taxable in US; Canadian withholding creditable on Form 1116
RRIF periodic pension payments (non-resident)	15% (treaty rate)	Fully taxable in US; Canadian withholding creditable on Form 1116
RRSP distribution while Canadian resident	Graduated rates (Canadian income tax)	Fully taxable in US; Canadian taxes creditable

Canada's TFSA (Tax-Free Savings Account) receives no favorable US treatment. The IRS taxes income and gains inside a TFSA as they accrue annually, because the TFSA is not recognized as a pension or retirement plan under the US-Canada treaty. US persons holding TFSAs should know they are reporting and paying US tax on account earnings each year while the Canadian side is tax-free—the reverse of the RRSP situation.

RRSP Reporting Obligations

A Canadian RRSP is a foreign financial account subject to FBAR reporting if your aggregate foreign accounts exceed $10,000 at any point during the year. It is also reportable on Form 8938 if you meet the FATCA thresholds. For the full reporting framework, see the US expat banking and taxes guide.

German Pension: The Treaty That Doesn't Protect US Citizens

Germany's statutory pension system (Gesetzliche Rentenversicherung, or GRV) is one of the most common pension accounts held by Americans who worked in Germany or married German spouses. The US-Germany income tax treaty (Article 17) states that pensions paid by one country to a resident of the other are taxable only in the country of residence—which would exempt US residents from German tax on GRV payments. Germany also generally does not withhold tax on GRV payments to non-resident beneficiaries if the total amount is below the annual German personal allowance.

For US citizens, however, the saving clause applies. The treaty's exclusive-taxing-rights provision cannot be used to exempt a US citizen from US taxation on German pension income. A US citizen living in the US who receives GRV payments owes US ordinary income tax on the full amount, with no treaty-based exemption. If Germany also taxes the pension (for a US citizen resident in Germany), the Foreign Tax Credit on Form 1116 offsets the German tax against the US liability.

German Private and Occupational Pensions

The Betriebsrente (employer occupational pension) is Germany's defined-contribution workplace pension. US tax treatment depends on the structure: a direct employer-funded promise (Direktzusage) may be treated as a deferred compensation arrangement; a pension fund (Pensionskasse) may be treated as a foreign trust or foreign pension fund. Treaty Article 18A provides some protection for contributions to recognized pension plans, but specific facts matter. Distributions are taxable in the US as ordinary income when received.

For most EU countries with US tax treaties—France, the Netherlands, Spain, and Sweden—the pattern is consistent: pension income is taxable in both countries under the relevant pension article, with the Foreign Tax Credit on Form 1116 preventing actual double payment of tax. The saving clause always removes any treaty-based full exemption for US citizens. The country-specific treaty article governs the exact allocation and withholding rates.

For countries without a US income tax treaty—covering many African, Middle Eastern, and some Asian countries—there is no treaty framework. Foreign pension income is fully taxable in the US, and you may claim a Foreign Tax Credit for foreign taxes paid under IRC Section 901 even without a treaty.

FBAR and Form 8938 for Foreign Pension Accounts

Foreign pension accounts create reporting obligations independent of tax liability.

Pension Type	FBAR Required?	Form 8938?	Other Forms
UK SIPP (defined contribution)	Yes (you have a named account)	Yes (if over threshold)	None typically
UK defined benefit workplace pension	Uncertain (no specific account)	Yes (present value)	None typically
UK state pension	No (not a bank/financial account)	No (government entitlement)	None
Canadian RRSP/RRIF	Yes (named account at financial institution)	Yes (if over threshold)	None currently (Form 8891 eliminated)
Canadian TFSA	Yes	Yes (if over threshold)	None; income taxable in US annually
German GRV (statutory pension)	No (government pension, no segregated account)	No (government entitlement, not a financial account)	None
German Betriebsrente / Pensionskasse	Yes if defined contribution with named account	Yes (if over threshold)	None typically; treaty analysis required
French / Dutch / Swedish government pension	No (government entitlement)	No (government entitlement)	None; treaty FTC applies

Data note: FBAR treatment of defined benefit pensions is not settled by IRS guidance. The majority view among expat tax practitioners is that defined benefit plans with no separately identifiable account value do not require FBAR reporting. Defined contribution plans with a named account balance clearly do. Consult a CPA for your specific plan structure.

Practical Steps: What to Do With a Foreign Pension

If you have or expect to receive a foreign pension and are a US citizen or green card holder, this is the minimum compliance sequence:

1. Identify the plan type: defined benefit vs. defined contribution; government vs. private employer vs. personal savings plan.
2. Check the treaty: Look up the US income tax treaty with that country (IRS.gov/treaties) and read the pension article. Note the saving clause limitation.
3. Determine reporting obligations: Is there a separately named account? If yes, FBAR is likely required if the aggregate foreign account total exceeds $10,000. Form 8938 if thresholds are met.
4. Determine current US tax on contributions and accruing income: Canadian RRSP and qualifying UK occupational pensions typically defer. German GRV contributions made by an employer during your German working years are generally deferred under Article 18A of the US-Germany treaty. Most private pensions without specific treaty deferral language are taxable as contributions are made.
5. Plan your Foreign Tax Credit position: When you take distributions, the Foreign Tax Credit on Form 1116 reduces your US tax by the foreign income taxes paid on the same income. The credit is limited to the ratio of foreign income to total income, so tax planning around distribution timing can optimize the credit.
6. Document everything: Annual statements, contribution records, and the exchange rates used to convert to USD. You will need these when the IRS eventually asks.

The expat 401(k) and IRA guide covers how to manage US retirement accounts alongside foreign pension income, including how to sequence Roth conversions to fill lower tax brackets before Social Security and pension income stack up in retirement.

Bottom Line

Foreign pensions do not disappear from the US tax picture just because you earned them abroad. The complexity varies by country and plan type: Canadian RRSPs are the most favorable (automatic deferral since 2014, no annual election required), UK pensions are fully taxable in the US but well-managed through the Foreign Tax Credit, and German pensions trigger US tax on distributions even when Germany waives withholding for non-residents.

The common mistake is assuming that because the foreign country doesn't tax you on the pension until retirement, the US doesn't tax you either. That is often wrong. For high-balance foreign pensions, a one-time consultation with a dual-qualified expat tax professional—who understands both the foreign pension rules and the US tax consequences—is almost always worth more than its cost.
