SSDI Work Credits: Missouri Claimants' Guide

Qualifying for Social Security Disability Insurance (SSDI) in Missouri requires more than a disabling medical condition. Before the Social Security Administration (SSA) evaluates your health, it first examines your work history. Work credits — the currency the SSA uses to measure your employment record — determine whether you are even eligible to apply. Understanding how credits are earned, how many you need, and what to do if you fall short can mean the difference between an approved claim and a denial that never gets reviewed on the merits.

What Are SSDI Work Credits?

Work credits are units assigned to your Social Security record based on your annual earnings from employment or self-employment. The SSA adjusts the dollar amount required to earn one credit each year. In 2024, you earn one credit for every $1,730 in covered wages or self-employment income, with a maximum of four credits per year.

Credits accumulate over your lifetime and never expire from your record. However, the SSA does not simply count how many you have — it also examines when they were earned relative to your disability onset date. This timing rule is what makes planning and early application so critical for Missouri residents who suspect their condition may worsen.

It is important to note that SSDI is a federal program administered uniformly nationwide. Missouri does not have a separate state-level work credit system. Whether you live in Kansas City, St. Louis, Springfield, or a rural county in the Ozarks, the same federal credit rules apply. However, Missouri's Disability Determination Services (DDS) office in Jefferson City handles the initial medical evaluation of your claim, and local attorneys familiar with Missouri DDS practices can provide meaningful guidance at that stage.

How Many Credits Do You Need?

The number of credits required to qualify for SSDI depends on your age at the time you become disabled. The SSA applies two overlapping tests:

• Total credits test: You generally need 40 credits earned over your lifetime, though younger workers need fewer.
• Recent work test: You must have earned a specified number of credits within a recent window before your disability onset. For most adults age 31 or older, this means 20 credits earned in the 10 years immediately before becoming disabled.

Younger workers face different thresholds. If you become disabled between ages 24 and 30, you need credits for half the period between age 21 and your disability date. Workers who become disabled before age 24 need only 6 credits earned in the 3 years before onset.

A practical example helps illustrate how this works. A 45-year-old Missouri worker who suffers a severe back injury must typically show 20 credits in the past 10 years — essentially, they must have worked and paid Social Security taxes for at least 5 of the last 10 years. A worker who left the workforce for a decade to care for a family member may have accumulated enough lifetime credits but still fail the recent work test. This gap is one of the most common and preventable reasons Missouri claimants are denied SSDI on technical grounds before their medical evidence is ever reviewed.

Gaps in Work History and Their Impact

Missouri residents often face work history gaps due to caregiving responsibilities, seasonal agricultural employment, chronic illness before a formal disability onset date, or periods of incarceration. The SSA evaluates your full Social Security earnings record, which you can review through your my Social Security account at ssa.gov.

If your earnings record shows gaps, consider the following before filing:

• Verify the accuracy of your earnings record. Employers sometimes fail to report wages correctly, and correcting an error could add credits you did not know you had.
• Determine whether any uncredited self-employment income — including gig work and contract labor — was properly reported and taxed through Schedule SE.
• Assess whether you are close enough to the credit threshold that returning to limited part-time work, within SSA's substantial gainful activity limits, might allow you to accumulate the credits you need before your condition prevents all employment.
• Explore Supplemental Security Income (SSI) as an alternative. SSI is need-based and does not require a work credit history, making it a potential option for Missouri residents who cannot meet SSDI's work requirements.

Protecting Your Insured Status in Missouri

Your SSDI insured status — often called your Date Last Insured (DLI) — is the deadline by which your disability must have begun to qualify under the recent work test. If you stop working and do not file promptly, your insured status will eventually lapse, even if you have 40 lifetime credits.

For Missouri claimants, this creates an urgent timing issue. If you became disabled before your DLI but did not file because you hoped to recover, you can still file a retroactive claim as long as you can establish that your disabling condition began while you were still insured. Medical records, treatment histories, and statements from Missouri-based treating physicians become critical evidence in proving an earlier onset date.

The SSA allows retroactive benefits of up to 12 months before the application date, but your condition must have existed before your DLI for the claim to succeed. Waiting to apply risks losing insured status permanently, leaving Missouri workers without access to the benefits they paid into throughout their careers.

What Happens After Credits Are Verified

Once the SSA confirms you meet the credit requirements, your claim moves to Missouri's DDS office for a medical review. DDS evaluators — working with SSA's five-step sequential evaluation process — assess whether your condition meets a listed impairment, prevents your past relevant work, or prevents any available work in the national economy given your age, education, and transferable skills.

Missouri claimants should be aware that initial DDS denial rates are high. Nationally, approximately 65–70 percent of SSDI applications are denied at the initial level. The appeals process — reconsideration, hearing before an Administrative Law Judge, Appeals Council review, and federal court — gives Missouri residents multiple opportunities to overcome an initial denial. Many successful claims are won at the ALJ hearing stage, where presenting detailed medical evidence and a thorough vocational argument can make a decisive difference.

Working with a Missouri attorney who focuses on Social Security disability claims provides practical advantages throughout this process. Attorneys can identify credit shortfalls early, gather objective medical evidence from Missouri treating sources, and represent you at hearings before the St. Louis or Kansas City hearing offices, or via video teleconference from any location in the state.
