Using Foreign Work Credits for SSDI: Totalization

If you worked in both the United States and another country, yes, foreign work credits can help you qualify for SSDI. The United States maintains bilateral Social Security agreements, known as totalization agreements, that let SSA combine coverage periods earned here with coverage earned abroad when neither country's total alone meets the eligibility requirements.

SSA's international agreements page explains that these agreements serve two purposes. They eliminate dual Social Security taxation, and they fill gaps in benefit protection for workers who divided their careers between two countries. For a disability claim in 2026, the second purpose is the one that matters.

The Problem Totalization Solves

A worker must be insured for SSDI, which means earning enough work credits, called quarters of coverage, in the right time frame. In 2026, one quarter of coverage requires $1,890 in covered earnings, with a maximum of four per year, and a worker disabled at age 31 or older generally needs at least 20 credits in the 10 years immediately before onset, per SSA's January 2026 publication How You Earn Credits.

Foreign contributions never appear on the United States earnings record. Before agreements existed, an immigrant with, say, ten years of American work and twenty years abroad could fail the insured-status tests in both countries and collect nothing from either. The agreements let each country count the other's coverage periods toward its own eligibility requirements, which is what the word totalization means.

The Six-Credit Floor

SSA imposes one hard limit on its side: the agreements allow totalization only if the worker has at least six quarters of United States coverage. At the 2026 rate, six credits require $11,340 in lifetime covered American earnings, though the credits must also satisfy the timing rules SSA applies to the specific claim.

A worker with fewer than six American credits cannot reach the United States system through totalization at all, no matter how long the foreign career. That worker's foreign pension possibilities are governed entirely by the other country's law.

The Agreement Countries in 2026

As of September 2026, SSA's table shows 31 agreements in force. The oldest is Italy, effective November 1, 1978, followed by Germany in 1979 and Switzerland in 1980. The list spans Europe, Canada (effective 1984), Japan, South Korea, Australia, and South American partners such as Chile, Brazil, and Uruguay. The newest is Romania, whose agreement entered into force September 1, 2026.

The full list with entry-into-force dates is published on SSA's international programs pages, and the count grows as new agreements are negotiated.

How Totalization Establishes Insured Status

When a claim is filed, SSA looks first at whether the worker meets insured status on American credits alone. If the American record falls short, SSA adds the coverage periods certified by the agreement country, month by month, toward the eligibility requirements. Each country performs the mirror-image calculation for its own program.

Whether the combined periods satisfy every timing requirement for a disability claim is determined case by case under SSA's international rules, so workers near the margins should not assume either outcome. What the agreements guarantee is that the foreign periods are counted rather than ignored.

The combined coverage never becomes part of the American earnings record itself. It is used for the eligibility test only, which is why the payment stays pro-rated even after totalization succeeds, and why foreign contributions never raise the American earnings SSA averages.

The Pro-Rated Benefit

Totalization establishes eligibility, not generosity. Once a worker qualifies using combined coverage, the United States pays a partial benefit based on the proportion of the total career completed under United States coverage, as SSA's agreements page describes.

A worker who spent a third of a covered career in the United States receives a United States benefit reflecting that American third, paid alongside whatever pro-rated pension the foreign country owes for its share. The foreign country applies its own minimum-coverage rules before counting American periods, mirroring the six-credit floor on this side.

Disability Claims Under the Agreements

Totalization changes the coverage math, not the medical standard. The claimant must still satisfy the full American definition of disability: an inability to perform substantial gainful activity, a condition expected to last at least 12 months or result in death, and the five-step evaluation SSA applies to every adult claim. In 2026, the substantial gainful activity guideline is $1,690 per month in earnings, or $2,830 for statutorily blind claimants, under figures published by SSA's Office of the Chief Actuary.

A person may file a totalization claim at any Social Security office in the United States or in the agreement country, which SSA notes on its agreements page.

Avoiding Double Taxation Going Forward

The agreements also decide which system covers current work, which protects future credits. The basic rule is territoriality: an employee is covered only by the country where the work is performed. The main exception, the detached-worker rule, keeps a temporarily transferred employee under the sending country's system, generally for assignments expected to last five years or less.

Workers exempted from one system carry a certificate of coverage issued by the other, and a self-employed United States citizen or resident attaches a copy of the foreign certificate to the federal tax return each year as proof of the exemption. Italy's agreement is the outlier, being based principally on nationality rather than transfer rules.

For future SSDI eligibility, the practical effect is that exempted workers keep building credits in one system instead of splitting contributions across two. Which system applies depends on the agreement's rules, not on personal preference.

What Totalization Cannot Do

The agreements cannot turn a foreign-only career into American benefits, because of the six-credit floor. They cannot add foreign years into the American benefit calculation, because the pro-rated payment reflects American coverage alone. And they cannot substitute for the medical definition of disability, which every SSDI claimant must meet regardless of where the credits were earned.

How benefits are delivered to beneficiaries living abroad, and how an agreement interacts with a foreign pension already in payment, are administration and payment-stage topics outside this site's focus on eligibility.

Frequently Asked Questions

Which countries have Social Security totalization agreements with the United States? SSA lists 31 countries with agreements in force as of September 2026, from Italy, in force since November 1978, to Romania, which entered into force September 1, 2026. The full table appears on SSA's international agreements page.

Do foreign work credits increase my SSDI payment amount? No. Foreign coverage can only help you meet the insured-status requirements. The United States then pays a partial, pro-rated benefit based on the share of the career completed under United States coverage.

Can I use totalization if I have no United States work credits at all? No. SSA will totalize United States and foreign coverage only if the worker has at least six quarters of United States coverage, roughly a year and a half of work at the 2026 credit rate of $1,890 per quarter.
