Foreign Pension and Social Security: How to Coordinate Both
To coordinate a foreign pension and U.S. Social Security, you choose the order in which you claim each benefit, time your Social Security so it grows, and plan around how each country taxes your income. You can collect both at the same time, and as of January 2024, a foreign pension no longer reduces your Social Security through the Windfall Elimination Provision (WEP), after the Social Security Fairness Act was signed into law on January 5, 2025. Roughly 700,000 Americans living abroad already receive Social Security, and many draw a foreign pension alongside it.
Coordination changes your outcome the most in four areas:
- Timing your claim: Delaying U.S. Social Security to age 70 raises your monthly benefit by about 8% for each year past full retirement age.
- Totalization agreements: Living in one of the 30 countries with a U.S. totalization agreement affects how your work credits and benefits are calculated.
- Currency and taxes: Benefits paid in different currencies and taxed in different countries can erode your income if you claim in the wrong order.
- Other retirement income, such as a 401(k), IRA, or taxable account, affects both benefit streams and how much of your Social Security benefits, up to 85%, becomes taxable.
Collecting Two Pensions? Start With a Clear Plan.
Below you will find practical, step-by-step guidance to coordinate both income streams and keep more of what you earned.
Can I Collect Both U.S. Social Security and a Foreign Pension?
Yes. You can receive U.S. Social Security benefits and a foreign pension at the same time, and one does not disqualify the other. The U.S. taxes its citizens and green card holders on worldwide income regardless of where they live, so your foreign pension and your Social Security are both part of the same U.S. return, even when you are retired overseas.
The practical question is no longer “Am I allowed to collect both?” but “How do I claim both so I keep the most money?” Most retirees treat the two benefits in isolation, claiming Social Security as soon as they are eligible and taking foreign pension distributions whenever it feels convenient. That approach often leads to:
- Claiming Social Security at 62 and locking in a permanently smaller benefit
- Paying more U.S. tax than necessary on the same retirement income
- Currency losses from converting benefits at unfavorable times
- Pushing more of your Social Security into the taxable range
For a fuller picture of how the U.S. treats your benefits while you live overseas, our guide to Social Security for Americans abroad walks through eligibility, where benefits can be paid, and what stays reportable.
Does a Foreign Pension Still Reduce My Social Security?
For most retirees, no. The Windfall Elimination Provision used to shrink Social Security benefits for people who also received a pension from work not covered by U.S. Social Security, which included many foreign pensions and foreign social security systems. The Social Security Fairness Act ended WEP and the related Government Pension Offset (GPO). December 2023 was the last month those rules applied, so your benefits payable from January 2024 forward are calculated without the WEP reduction.
| What changed | Before the repeal | From January 2024 onward |
|---|---|---|
| WEP reduction | Foreign pension could cut your Social Security | No WEP reduction applies |
| Benefit timing strategy | Complex planning to limit WEP | Plan around tax and timing, not WEP |
| Past benefits | Reduced for affected retirees | One-time payment back to January 2024 for those affected |
If your Social Security was reduced in the past because of a foreign pension, you may be owed a retroactive adjustment. Confirm your updated benefit amount through your ‘My Social Security account‘ or by contacting the SSA directly. The repeal removes a major planning headache, but it does not make your Social Security tax-free: up to 85% of your benefits can still be taxable depending on your total income.
When Should I Claim Each Benefit?
Your best claim order depends on three factors: which countries are involved, the relative size of each benefit, and the tax treatment in both countries.
Two broad approaches cover most situations
- Claim the foreign pension first, delay Social Security. Many foreign pensions begin earlier than the U.S. full retirement age. Drawing the foreign pension first can cover your living costs while you delay Social Security until age 70, locking in the larger lifetime benefit.
- Claim both together. In a high-tax country where the Foreign Tax Credit already offsets most of your U.S. tax, taking both benefits at once can simplify your planning without raising your overall tax bill.
Here is how that first strategy can play out:
| Claiming approach | Monthly U.S. benefit | Result |
|---|---|---|
| Claim Social Security at 62 | About $2,400 | Smaller benefit locked in for life |
| Delay Social Security to 70 | About $4,250 | Roughly $22,000 more per year, for life |
In this example, a retiree in the United Kingdom lives on an annual UK pension from age 62 and delays U.S. Social Security to 70. Claiming at 62 locks in a permanently reduced benefit, while waiting until 70 raises the monthly U.S. benefit by roughly 75%, an increase that continues for the rest of their life and helps protect against outliving their savings.
How Do Totalization Agreements Affect My Strategy?
The U.S. has Social Security totalization agreements with 30 countries. These agreements prevent double Social Security taxation and let you combine work credits from both countries to qualify for benefits. Your coordination strategy looks different depending on whether your country has one.
| Situation | What it means for you | Planning focus |
|---|---|---|
| Agreement country (UK, Canada, Germany, Australia, and 26 others) | Combined credits, no double Social Security tax | Optimize claim timing and tax treatment |
| Non-agreement country | No credit combining, watch for double Social Security tax | Sequence claims to limit tax friction |
A few country examples show how the details shift:
- Germany: German pension payments often receive favorable treaty treatment, so claiming the German benefit first while delaying U.S. Social Security can work well.
- Canada: The U.S.-Canada treaty has specific rules for cross-border pensions, and splitting claims across tax years can help manage your brackets.
- Australia: Australian Superannuation has its own quirks, and the choice between a lump sum and a pension stream can change your U.S. tax outcome significantly.

How Are My Foreign Pension and Social Security Taxed?
Both income streams flow onto your U.S. tax return, but they are reported differently, and your country of residence may tax them too. The high-level picture:
| Income stream | U.S. treatment | Common foreign treatment |
|---|---|---|
| U.S. Social Security | Up to 85% taxable based on total income | Varies; some treaties assign taxing rights to your country of residence |
| Foreign pension | Generally taxable; reporting depends on the plan | Often taxed where you live |
The mechanics of reporting a foreign pension, including which plans trigger extra forms, are covered in depth in our guide to how foreign pensions are taxed in the U.S. The tools that keep you from being taxed twice are the Foreign Tax Credit and, for earned income before retirement, the Foreign Earned Income Exclusion. Because retirement income is usually passive, the Foreign Tax Credit tends to be the more relevant tool once you stop working.
If you are a retiree living abroad, coordinating Social Security, a foreign pension, and your U.S. taxes can mean keeping thousands more across your retirement. Learn more about how we help retirees abroad file with confidence.
How Do I Coordinate With My Other Retirement Income?
Your Social Security and foreign pension are two pieces of a larger plan that also includes any 401(k), IRA, or taxable accounts. The order you draw from them affects how much of your Social Security becomes taxable and which tax bracket you land in each year. A sensible default sequence:
- Use foreign pension income in lower-tax years to fill up the bottom brackets
- Claim Social Security when it best balances your lifetime benefit and your annual tax picture
- Coordinate 401(k) and IRA withdrawals to manage your bracket and limit how much Social Security is taxed
Where you live in retirement matters too. If you keep U.S. ties, some states still tax retirement income, while others do not. Our overview of states that do not tax retirement income and our guide to tax planning when you retire abroad can help you weigh those choices.
What Are the Most Common Coordination Mistakes?
- Claiming Social Security too early: Taking benefits at 62 out of habit can permanently reduce a benefit you will rely on for decades.
- Ignoring currency trends: Prioritizing the wrong benefit during a period of currency swings can cut your real spending power.
- Overlooking state tax: Assuming you owe no U.S. state tax when a former home state still treats you as a resident.
- Missing treaty benefits: Failing to use available tax treaty provisions that could reduce or eliminate double taxation.
How Do I Build My Coordination Plan?
You do not need to solve everything at once. Working through it in phases keeps the process manageable.
- Phase 1, the next 30 days: Request your Social Security statement and your foreign pension projections, and review your country’s tax treaty with the U.S.
- Phase 2, three to six months: Model a few claiming scenarios at current exchange rates, review your other retirement accounts for the best withdrawal order, and read through our expat retirement planning guide for the full framework.
- Phase 3, every year: Revisit your plan as tax laws and exchange rates change, and adjust timing as your circumstances evolve.
When Should I Get Professional Help?
Coordinating two benefit systems across two tax codes gets complicated quickly. It is worth bringing in an expat tax professional when:
- Your combined retirement income will exceed about $100,000 a year
- You have pensions from more than one foreign country
- Your foreign pension involves a lump sum versus a stream decision
- You hold significant other retirement assets that need to be sequenced
- A non-citizen spouse is involved, which affects Social Security survivor and spousal benefits
If you are a retiree living abroad, the right coordination plan can mean thousands of dollars more across your retirement and far less stress at tax time. Learn more about how we help expat retirees get both benefit streams right by reaching out to our Customer Champions.

Frequently Asked Questions
Yes. There is no rule preventing you from collecting both, and many American retirees abroad do exactly that. The goal is to coordinate the timing and tax treatment so you keep as much as possible.
For benefits payable from January 2024 onward, no. The Social Security Fairness Act ended the Windfall Elimination Provision, which previously reduced Social Security benefits for people with a non-covered pension, including many foreign pensions.
It can be. Up to 85% of your Social Security benefits may be taxable on your U.S. return, depending on your total income, and your country of residence may also have taxing rights under a treaty.
It depends on the size of each benefit and your tax situation, but a common approach is to draw the foreign pension earlier and delay Social Security toward age 70 to lock in a larger lifetime benefit.
Totalization agreements primarily prevent double Social Security taxation and allow you to combine work credits to qualify for benefits. They do not eliminate income tax, but they do shape your overall coordination strategy.
