SSDI Work Credits: How Many You Need in NH

Social Security Disability Insurance is not a program anyone can simply apply for and receive. Unlike Supplemental Security Income, which is needs-based, SSDI is an earned benefit — one tied directly to your work history. Before the Social Security Administration even evaluates your medical condition, it checks whether you have accumulated enough work credits to qualify. For New Hampshire residents navigating this process, understanding how credits are calculated and how many you need is the essential first step.

What Are Social Security Work Credits?

Work credits are the Social Security Administration's way of measuring your participation in the workforce over your lifetime. Every year you work and pay Social Security taxes through your paycheck or self-employment, you accumulate credits based on your total earnings. The SSA awards up to four credits per year, regardless of how much you earn above the threshold.

The dollar amount required to earn a single credit changes annually with inflation. For 2025, you earn one credit for every $1,810 in covered earnings. That means earning $7,240 in 2025 gives you the maximum four credits for the year. In 2024, the threshold was $1,730 per credit. These amounts are modest enough that most full-time workers in New Hampshire earn their maximum four credits with little difficulty — the challenge arises when a disability forces someone out of the workforce before they have built up enough of a work history.

Credits accumulate over your entire working life and never expire from your record. However, the recency of your credits matters enormously for SSDI eligibility, which is where many New Hampshire applicants run into difficulty.

How Many Work Credits Do You Need for SSDI?

The total number of credits required to qualify for SSDI depends on your age at the time you become disabled. The SSA uses a sliding scale — younger workers need fewer credits because they have had less time to accumulate them.

• Before age 24: You need only 6 credits earned in the 3-year period ending when your disability begins.
• Ages 24–30: You need credits for half the time between age 21 and the onset of your disability.
• Age 31 or older: You generally need 40 credits total, with 20 of those earned in the 10 years immediately before your disability began.

The 40/20 rule that applies to most adult workers is the standard most people encounter. Put plainly: if you become disabled at age 50, you need 40 total credits (roughly 10 years of work), and at least 20 of those credits must come from the decade just before your disability onset. Someone who worked steadily through their 30s but left the workforce at 40 to care for a family member could find themselves disqualified by age 50 if they did not return to work — even if they have more than 40 lifetime credits.

This recency requirement catches many New Hampshire applicants off guard, particularly those who took extended breaks from employment due to caregiving, seasonal work patterns, or prior health issues.

New Hampshire Workers and Common Credit Gaps

New Hampshire's economy includes a significant proportion of small business owners, seasonal workers in tourism and hospitality, and self-employed tradespeople — all groups that face particular challenges with work credit accumulation.

Self-employed New Hampshire residents pay self-employment tax, which counts toward Social Security credits just like wages from an employer. However, underreporting income — a tempting shortcut for some small business owners — directly reduces the credits you accumulate and can leave you short when disability strikes.

Seasonal workers who earn substantial wages during the summer or ski season may meet the annual credit threshold, but those who work only part of the year at lower wages may fall short of four credits in some years. Over a career, these gaps add up and can affect whether the 20-in-10 rule is satisfied.

New Hampshire residents who worked in states with reciprocal arrangements or who spent time working overseas should also be aware that only earnings covered under the U.S. Social Security system count toward SSDI credits. Work performed under a foreign social security system generally does not count, though totalization agreements with certain countries can sometimes bridge this gap.

Checking Your Work Credit History

Before filing an SSDI claim in New Hampshire, every applicant should verify their actual credit total through the Social Security Administration. The SSA maintains a complete record of your reported earnings and credits, and errors in this record — while uncommon — do occur. A missing year of wages can be the difference between approval and denial at the technical eligibility stage.

You can review your earnings record and estimated credit total by creating a free account at the official SSA website. The SSA also mails periodic Social Security Statements, though these mailings have been inconsistent in recent years. New Hampshire residents can also visit the SSA's Manchester field office or the Nashua office to review records in person or request corrections to inaccurate information.

If you discover errors in your earnings record, the SSA requires documentation — typically W-2 forms, tax returns, or pay stubs — to correct them. Gather this documentation as early as possible, because records older than three years can be harder to verify and correct.

What Happens If You Don't Have Enough Credits

Falling short of the required work credits does not necessarily end your options. New Hampshire residents who lack sufficient SSDI credits may still qualify for Supplemental Security Income, the needs-based companion program. SSI uses the same medical disability standards as SSDI but has no work history requirement — instead, it imposes strict income and asset limits.

Additionally, individuals who became disabled before age 22 may qualify as an adult disabled child on a parent's Social Security record, even without their own work history. Surviving spouses and divorced spouses may also qualify for disability benefits through a deceased or former spouse's record under certain conditions.

For those who are still working and approaching the credit threshold, timing matters. If you anticipate a disabling condition worsening, continuing to work long enough to satisfy the 20-in-10 requirement before your condition forces you to stop can preserve your eligibility for a substantially larger monthly benefit than SSI provides.

The SSDI application process in New Hampshire, as elsewhere, involves multiple stages — initial application, reconsideration, and potentially a hearing before an administrative law judge. Technical denials for insufficient credits typically happen early and can be difficult to overcome without actually earning the missing credits. This makes pre-application credit verification one of the most valuable steps any prospective claimant can take.
