How Many Work Credits Do You Need for SSDI?

Social Security Disability Insurance (SSDI) is a federal program that provides monthly benefits to workers who become disabled and can no longer earn a living. But unlike Supplemental Security Income (SSI), SSDI is not a needs-based program — it is an earned benefit. To qualify, you must have paid into the Social Security system long enough to accumulate sufficient work credits. Understanding how these credits work is the first step to knowing whether you are eligible to file a claim in North Dakota.

What Are Social Security Work Credits?

Work credits are the Social Security Administration's (SSA) way of measuring your work history. Every year you work and pay Social Security taxes, you earn credits based on your income. As of 2025, you earn one work credit for every $1,810 in wages or self-employment income, and you can earn a maximum of four credits per year.

These credits do not expire — they remain on your earnings record permanently. However, the number of credits you need to qualify for SSDI depends on your age at the time you become disabled. The SSA applies two separate credit tests: the duration-of-work test and the recent-work test.

The Two Credit Tests You Must Pass

Many applicants focus only on the total number of credits, but the SSA actually requires you to satisfy two distinct requirements simultaneously. Failing either one will result in a denial on technical grounds, before the SSA even evaluates your medical condition.

• Duration-of-Work Test: This measures how long you have worked over your lifetime. Younger workers need fewer total credits because they have had less time to accumulate them.
• Recent-Work Test: This measures how recently you worked before your disability began. Social Security is designed for active workers — if you stopped working many years ago, you may no longer be insured even if you have 40 lifetime credits.

Both tests must be met. A common and costly mistake is assuming that a long work history automatically qualifies you, when a gap in recent employment may have caused your insured status to lapse.

How Many Credits You Need Based on Your Age

The SSA uses a sliding scale tied to your age at the onset of disability. Here is a breakdown of the general requirements:

• Before age 24: You need 6 credits earned in the 3-year period ending when your disability begins.
• Ages 24 to 31: You need credits for half the time between age 21 and the age you became disabled. For example, if you become disabled at 27, you need 3 years of work (12 credits) out of the past 6 years.
• Age 31 to 42: You need 20 credits total, all earned within the 10 years immediately before your disability.
• Ages 44 through 60: The required credits increase by 2 for every 2 years of age. For example, a 50-year-old needs 28 credits; a 60-year-old needs 38 credits.
• Age 62 or older: You generally need 40 credits, with 20 earned in the last 10 years before your disability onset date.

Blind applicants have a limited exception — they must meet the duration-of-work test but are not required to satisfy the recent-work test.

Your Date Last Insured: A Critical Deadline in North Dakota Claims

Your Date Last Insured (DLI) is one of the most important — and most misunderstood — concepts in SSDI law. It is the last date on which you meet the SSA's credit requirements. If you stop working and your credits run out, your DLI passes and you are no longer eligible for SSDI, regardless of how severe your disability becomes afterward.

For North Dakota claimants, this is especially significant in industries like agriculture, oil and gas, and construction, where workers may have gaps in employment or periods of self-employment that were not properly reported to the SSA. A worker who spent years on a family farm or worked seasonal jobs may have fewer credited quarters than expected.

You can find your DLI by reviewing your Social Security Statement, available at ssa.gov/myaccount. If your disability began after your DLI, your claim will be denied on technical grounds. In those situations, a different program — SSI — may still be available depending on your income and resources.

What to Do If You Do Not Have Enough Work Credits

A technical denial is not the end of the road. Depending on your situation, several alternatives deserve consideration:

• Supplemental Security Income (SSI): SSI does not require work credits. It is based on financial need and available to disabled individuals with limited income and assets. North Dakota residents who qualify may receive both SSI and Medicaid simultaneously.
• Disability Onset Date Review: An attorney can review your medical records to determine whether your disability actually began earlier than you initially reported — potentially within your insured period.
• Childhood Disability Benefits: Adults disabled before age 22 may qualify based on a parent's work record if the parent is deceased, retired, or disabled.
• Disabled Widow(er)'s Benefits: If your spouse was insured under Social Security, you may qualify based on their record if you are between 50 and 60 and became disabled within a specific timeframe after their death.

North Dakota has a relatively low population density, which means many disability claimants are self-employed farmers, ranchers, or small business owners. If you were self-employed, Social Security only credits earnings on which you actually paid self-employment tax. Underreporting income for years — a common tax strategy — can backfire severely when it comes time to claim SSDI benefits.

If you believe your earnings record is inaccurate, you have the right to request a correction. The SSA generally allows corrections for errors within the past three years, three months, and fifteen days, though some exceptions apply. Acting quickly is essential — the longer you wait, the harder it becomes to correct historical earnings records.

Work credits are just the threshold. Once you clear the technical eligibility hurdle, the SSA then evaluates whether your medical condition meets its definition of disability — a separate and often more difficult challenge. Having legal representation significantly improves outcomes at every stage of the process, from the initial application through hearings before an Administrative Law Judge.
