US Social Security payments don’t stop when you move to Portugal. Portugal is not on the SSA’s restricted country list, and the mechanics of receiving your benefit abroad are well established. What does change — and what most articles skip over — is how your benefit is taxed once you become a Portuguese tax resident, and what the SSA expects from you annually to keep payments uninterrupted.
Receiving Your Payments: The Setup That Actually Works
Portugal participates in the SSA’s International Direct Deposit (IDD) programme, meaning the SSA can deposit directly to a Portuguese bank account, automatically converting from USD to euros at the daily exchange rate before deposit. The official form is SSA-1199-PE (International Direct Deposit for Portugal), available from the Federal Benefits Unit at the US Embassy.
In practice, most expats route through a US bank account instead. The reason is control: the SSA’s conversion rate is set at the time of payment, which you can’t influence. By receiving in a US account and transferring yourself — using Wise, Revolut, or a similar low-fee service — you can time conversions and get better rates. You also avoid foreign transaction fees that apply to the Direct Express debit card option (3% at merchant locations plus flat ATM fees), which is worth ruling out immediately.
For anyone keeping a US account, the banks that remain expat-friendly after you move matter here — Schwab International, certain credit unions, and some legacy accounts at larger banks are more stable for non-residents than others.
One procedural change to know: as of April 2025, the SSA no longer verifies identity over the phone for direct deposit changes. Any change to your direct deposit details now requires ID.me identity verification online or an in-person appointment at the FBU in Lisbon. If you’re setting this up from Portugal, contact the FBU in advance:

The Annual Questionnaire — Do Not Ignore This
Once you’re living abroad, the SSA sends a Foreign Enforcement Questionnaire (Form SSA-7161 or SSA-7162) every one to two years. It confirms you’re still alive, still eligible, and still meeting benefit conditions. The form goes to whatever address the SSA has on file.
If you don’t respond, the SSA suspends your payments. Reinstatement takes 7–10 business days after they receive the completed form — but getting to that point can take weeks if mail is delayed or if your address is stale. Keep your address current with the FBU, and when a questionnaire arrives, respond immediately rather than setting it aside.
If I were doing this today, I would update my SSA address, confirm my direct deposit details, and download a current Benefit Verification Letter from ssa.gov before leaving the US. These take about 15 minutes and save significant frustration once you’re abroad.
How Your Benefit Is Taxed — The Part Most Articles Get Wrong
This is where you’ll find genuinely conflicting information, including on well-known expat tax sites. Here’s the accurate version.
US Federal Tax
Up to 85% of your Social Security benefit can be subject to US federal income tax, depending on your “combined income” (AGI + non-taxable interest + half of Social Security):
| Combined Income | SS Portion Taxable |
|---|---|
| Below $25,000 single / $32,000 joint | 0% |
| $25,000–$34,000 single / $32,000–$44,000 joint | Up to 50% |
| Above $34,000 single / $44,000 joint | Up to 85% |
These thresholds haven’t moved since 1983. At current benefit levels, most recipients with any additional income — a pension, rental income, IRA withdrawals — find a portion of their SS taxable. As a US citizen abroad, you still file a 1040 every year regardless.
How Portugal Taxes Your Social Security — The Nuanced Answer
Many articles state that US Social Security is “taxable only in the US” under the tax treaty. That’s an oversimplification that can cause real filing errors.
The US–Portugal tax treaty (signed 1994) allocates primary taxing rights over Social Security-equivalent payments, but the treaty’s saving clause allows the US to tax its own citizens as if the treaty didn’t exist. More importantly, Portugal, as your country of residence, has the right to include US Social Security in your Portuguese taxable income. Once you’re a Portuguese tax resident — which you become after 183 days in-country or by establishing your habitual residence — your worldwide income, including US Social Security, is within scope for Portuguese IRS.
What this means practically: both countries can claim taxing rights on your Social Security. The mechanism that prevents you paying full tax to both is the Foreign Tax Credit — you claim Portuguese taxes paid on the Social Security income as a credit against your US bill, or vice versa depending on which country’s rate is higher. The key point is that you file in both countries and use the FTC to avoid double payment, rather than assuming a treaty exemption means you don’t report it somewhere.
This is consistently confirmed by Greenback Tax Services, Bright!Tax, and Dimov Tax — all firms that specialise in US-Portugal returns. It’s also why the FATCA and IRS obligations article covers the FTC in detail: for most retirees in Portugal, it’s the primary tool for managing the overlap.
The Totalization Agreement
The US–Portugal Totalization Agreement prevents dual Social Security contributions — you don’t pay into both countries’ systems simultaneously for the same work. The rules depend on duration and employment type:
- Working in Portugal for fewer than 5 years: generally continue paying US Social Security taxes
- Working in Portugal for 5+ years: generally shift to Portuguese Segurança Social contributions
For retirees already drawing Social Security rather than still contributing, the practical effect is simpler: you don’t separately owe Portuguese Segurança Social contributions on your US benefit amount. Your benefit is calculated based on your US work history and doesn’t change based on time spent in Portugal.
The Totalization Agreement also allows combined work records. If you worked in both countries during your career but didn’t accumulate enough credits in either to qualify for a benefit independently, your records can be combined. This primarily benefits people who split careers internationally.
Early Retirement and the Earnings Limit
If you’re collecting Social Security before your Full Retirement Age (FRA) and you earn income in Portugal — whether through employment, freelancing, or recibos verdes — US earnings limits apply. In 2026, earning above the annual exempt amount before FRA triggers a temporary benefit reduction, which is credited back after you reach FRA.
Once you reach full retirement age, there is no earnings limit. You can work as much as you like in Portugal — employed, self-employed, or consulting — without it affecting your monthly payment.
Currency Risk Is Real
Your Social Security is paid in US dollars. Portugal runs on euros. The purchasing power of your monthly payment in Portugal fluctuates with the USD/EUR exchange rate.
When the dollar strengthens, your effective income in Portugal rises. When it weakens, your purchasing power drops — even though your nominal benefit stays the same. For most retirees, Social Security covers a meaningful portion of living costs in Portugal but not all of them; the cost of living breakdown by city gives a realistic sense of how far a dollar-denominated income goes in Lisbon vs Porto vs the Algarve vs smaller interior cities.
Most expats supplement Social Security with some combination of IRA or 401(k) withdrawals, investment income, rental income from property in either country, or part-time remote work. Each of those income types is taxed differently under the US–Portugal treaty framework — the double taxation treaty guide covers private pensions and retirement accounts specifically.
For Non-US Citizen Spouses
If your spouse is not a US citizen, their eligibility for spousal or survivor benefits on your record depends on several factors including length of marriage and whether they reside in the US or abroad. The SSA’s Payments Abroad Screening Tool (linked in sources above) gives a preliminary assessment; the FBU in Lisbon handles the detailed case-by-case questions.
A Portuguese spouse who paid Segurança Social contributions during a career in Portugal also has their own entitlement to Portuguese pension benefits, which is separate from your US Social Security.
Before You Leave the US
Log into ssa.gov and do four things: update your address or set up a reliable forwarding address, confirm your direct deposit details, download a Benefit Verification Letter (useful for D7 visa applications and Portuguese bank account openings), and check whether you have any pending correspondence from the SSA. Doing this before you leave is significantly easier than doing it from Portugal — the FBU is helpful but their phone window is limited.
Your NIF will be required for your Portuguese bank account, which is where your Social Security will ultimately land whether you receive it there directly or transfer from a US account. Get your NIF sorted early in the process — it’s needed for banking, the Portuguese tax system, and essentially every official interaction in Portugal.
