If you spent part of your career working outside the United States, you may be wondering whether that work counts toward SSDI eligibility. The short answer is: it depends on where you worked, who paid your wages, and which country's Social Security system covered you at the time. Here's how the SSA sorts this out.
SSDI — Social Security Disability Insurance — is an earned benefit. To qualify, you must have accumulated enough work credits through employment covered by the U.S. Social Security system. In 2024, you earn one credit for every $1,730 in covered earnings, up to four credits per year (these thresholds adjust annually).
Most workers need 40 credits total, with at least 20 earned in the 10 years before becoming disabled. Younger workers may qualify with fewer credits under a sliding scale.
The critical phrase here is covered earnings — meaning wages on which U.S. Social Security taxes (FICA) were withheld. Work done abroad doesn't automatically generate U.S. credits, but several scenarios can change that.
If an American company employed you overseas and paid you as a U.S.-based employee, your wages likely remained subject to FICA taxation — which means those earnings count toward your U.S. work credits just like domestic employment would. This is common for federal contractors, diplomats, military contractors, and multinational corporate employees on U.S. payroll.
U.S. citizens and lawful permanent residents are generally subject to U.S. tax law on worldwide income, including self-employment income. If you filed Schedule SE and paid self-employment taxes while working abroad, those earnings likely generated U.S. work credits.
This is where things get more nuanced. The United States has Totalization Agreements with roughly 30 countries — including the UK, Canada, Germany, Japan, Australia, and others. These treaties prevent workers from being double-taxed by two Social Security systems simultaneously.
Under a Totalization Agreement, if you don't have enough U.S. work credits to qualify for SSDI on your own, the SSA can combine your U.S. credits with credits earned in the treaty country to help you meet the eligibility threshold. However, this doesn't mean you receive a full SSDI benefit — the SSA calculates a pro-rated benefit based only on your U.S. covered earnings.
Key point: Totalization only helps you meet the threshold. Your actual benefit amount is still based solely on your U.S. earnings record.
| Situation | U.S. Credits Earned? | Totalization Applies? |
|---|---|---|
| U.S. employer, worked abroad on U.S. payroll | Yes | Not needed |
| Foreign employer, country with Totalization Agreement | No (foreign credits only) | Possibly yes |
| Foreign employer, no Totalization Agreement | No | No |
| Self-employed abroad, paid U.S. SE taxes | Yes | Not needed |
If you worked for a foreign employer in a country without a Totalization Agreement, those wages typically do not generate U.S. work credits and cannot be combined with any U.S. credits you have. Countries without Totalization Agreements include most of Southeast Asia, much of the Middle East, and large parts of Africa and Latin America.
Even within Totalization Agreement countries, if you were covered solely by the foreign system — meaning you paid into their Social Security equivalent and were specifically exempt from U.S. Social Security taxes under the treaty — those earnings won't build your U.S. record.
Even when Totalization helps you qualify, your monthly benefit amount is determined by your Average Indexed Monthly Earnings (AIME) — a formula drawn entirely from your U.S.-covered wages. A shorter U.S. work history generally produces a lower benefit amount than a full domestic career. The SSA's formula is progressive, meaning it replaces a higher percentage of lower earnings, but a limited U.S. record still typically means a lower payment.
Several factors determine how out-of-country work ultimately affects a specific SSDI claim:
Someone who spent 15 years on a U.S. corporate payroll abroad, with FICA taxes withheld throughout, may have a fully intact U.S. earnings record and face no complications at all. Someone who worked independently in a non-agreement country for a decade and then returned to the U.S. for only a few years may fall short of the credit threshold regardless of how serious their disability is. A third person — a U.S. citizen who worked in Canada and paid into both systems — might use Totalization to cross the eligibility line, but receive a benefit that reflects only a partial U.S. earnings record.
The work history piece is just one side of the SSDI equation. Even someone with a spotless U.S. earnings record still needs to satisfy the SSA's medical definition of disability — a condition severe enough to prevent substantial gainful activity (SGA) for at least 12 months or expected to result in death.
How your particular combination of foreign employment, tax history, and medical circumstances fits into this framework isn't something general program rules alone can resolve.
