Your earnings do not determine SSDI may be able to access — work credits do

Social Security Disability Insurance (SSDI) does not have an income limit for getting approved. The Social Security Administration does not care how much money you make when you explore. What matters instead is whether you have earned enough work credits — a separate measure based on how long you have worked and paid Social Security taxes, not how much you earned in any single year.

Once you are receiving SSDI, however, there is a limit on how much you can earn without losing your benefits. That limit is called the Substantial Gainful Activity (SGA) threshold, and it changes every year. For 2024, the SGA threshold is $1,550 per month for non-blind beneficiaries and $2,590 per month for blind beneficiaries. If you earn more than that amount in a month, Social Security will consider you able to work and may stop your benefits.

Key Takeaways

  • You need a minimum number of work credits to be found disabled, but there is no maximum income that disqualifies you from SSDI approval.
  • Work credits are earned by paying Social Security taxes on wages, and you can earn up to four credits per year regardless of how much you make.
  • Once approved for SSDI, you cannot earn more than the SGA threshold ($1,550 monthly for non-blind workers in 2024) without risking benefit termination.
  • The SGA threshold increases each year based on national wage trends, so the amount that triggers a review changes annually.
  • Work incentive programs like the Trial Work Period allow you to test your ability to work without when ready losing SSDI, even if you exceed SGA temporarily.

How work credits connect to your SSDI approval

To be found disabled under SSDI rules, you must have worked long enough to earn sufficient work credits. The number of credits you need depends on your age when you become disabled. Generally, you need 40 credits total, with at least 20 of those earned in the 10 years before you became disabled. Younger workers need fewer credits.

You earn one work credit for every $1,550 of wages you earn in 2024 (this amount changes yearly). You can earn a maximum of four credits per year. This means you could earn $1,550 in a single month and get one credit, or spread your earnings across the year — the total amount does not matter, only that you crossed the threshold. A person earning $50,000 per year and a person earning $6,200 per year both earn the same four credits that year, as long as both hit the minimum thresholds.

Because work credits are based on whether you worked and paid taxes, not how much you earned, a high-income worker and a low-income worker can have identical work credit records. The Social Security Administration will not deny you SSDI because you earned too much before you became disabled.

The Substantial Gainful Activity threshold after approval

Once Social Security approves your SSDI claim, the earnings rules change. You enter what is called the Substantial Gainful Activity (SGA) test. If you work and earn more than the SGA threshold in any month, Social Security will review your case and may conclude that you are no longer disabled, because you have shown you can perform substantial work.

For 2024, the SGA threshold is $1,550 per month for workers who are not blind. For blind workers, it is $2,590 per month. These amounts are set by federal law and increase each year when the national average wage index rises. In 2023, the non-blind threshold was $1,470; in 2022, it was $1,350. The threshold typically increases by $50 to $100 annually, though the exact amount varies.

Earning below the SGA threshold does not automatically protect your benefits — Social Security still reviews your medical condition — but it does mean your earnings alone will not trigger a work capacity finding. Earning above it signals to Social Security that a review is needed.

How the Trial Work Period protects you while testing work

Social Security recognizes that many disabled people want to test whether they can work before risking their benefits. For this reason, SSDI includes a Trial Work Period (TWP) that lasts nine months. During the TWP, you can earn any amount — even well above the SGA threshold — and keep your full SSDI benefit check each month.

The nine months do not have to be consecutive. Social Security counts only the months in which you earn $1,050 or more (in 2024) as trial work months. If you work part-time some months and not at all in others, only the months you crossed that threshold count toward your nine. Once you have used nine trial work months, you enter the Extended may be able to access Period (EPE), which lasts 36 months. During the EPE, if you earn above SGA in any month, you lose your benefit that month only — you do not lose SSDI itself, and your benefits resume the next month if you drop below SGA again.

After the EPE ends, if you are still working and earning above SGA, your SSDI case closes. You can request reinstatement within five years if your work attempt fails, but you will need to reapply and meet current medical criteria.

Self-employment and earnings calculations

If you are self-employed, Social Security counts your net profit (revenue minus business expenses) as your earnings. The SGA threshold applies the same way — if your net monthly profit exceeds $1,550, you may be found able to work. Self-employed beneficiaries often face closer scrutiny because Social Security must verify that the business is genuinely yours and that the reported income is accurate.

You must report self-employment income to Social Security, even during the Trial Work Period. Underreporting or failing to report can result in overpayment notices and benefit suspension. If you own a business or are considering self-employment while on SSDI, contact your local Social Security office or a work incentive planning and information (WIPA) project before you start, so you understand how your specific situation will be treated.

Other income sources do not affect SSDI approval or ongoing benefits

SSDI is not means-tested, meaning other income — such as savings, investments, rental income, or family support — does not count against you. You could have a million dollars in the bank and still be approved for SSDI, as long as you meet the medical and work credit requirements. This is different from Supplemental Security Income (SSI), which does have strict asset and income limits.

Once you are on SSDI, non-work income also does not affect your monthly benefit amount or your may be able to access. Your SSDI payment is based solely on your own Social Security earnings record, not on what else you have or earn. However, if you are also receiving SSI (which some disabled people do), then other income will reduce your SSI payment.

What happens if you exceed SGA and Social Security reviews your case

If you earn above the SGA threshold, Social Security will send you a letter asking you to report your work activity and provide details about your job duties, hours, and pay. This does not automatically mean you will lose benefits. Social Security will review your medical records and may ask your doctor whether the work you are doing is consistent with your disability.

Some people can work above SGA and still be found disabled if the work is part-time, irregular, or supported by accommodations that would not be available in a regular job. For example, if you work 10 hours per week at a job designed specifically for people with your condition, Social Security may find that you are still disabled despite earning above SGA. The information depends on the specifics of your medical condition and your actual work capacity, not the earnings number alone.

If Social Security concludes you are no longer disabled, you will receive advance notice and an opportunity to request a hearing before your benefits stop. You can also request expedited reinstatement if your work attempt fails within five years.

Frequently Asked Questions

Can I be denied SSDI because I earned too much money before I became disabled?

No. SSDI approval is based on work credits, not income level. You need enough work credits from paying Social Security taxes, but there is no maximum earnings that disqualifies you. A high-income worker and a low-income worker can have identical may be able to access.

What is the difference between the SGA threshold and work credits?

Work credits determine whether you can be found disabled in the first place — you need a minimum number based on your age. The SGA threshold applies after you are approved and limits how much you can earn each month without triggering a work capacity review. They are two separate rules.

If I earn $2,000 one month during my Trial Work Period, do I lose my SSDI check?

No. During the nine-month Trial Work Period, you keep your full SSDI benefit every month, no matter how much you earn. That month counts as one of your nine trial work months, but you do not lose any payment.

Does money from my savings or investments count as earnings for SSDI?

No. SSDI only counts work earnings — wages from a job or net profit from self-employment. Savings, investments, rental income, and other non-work income do not affect your SSDI approval or benefits. SSDI has no asset limit.

Can the SGA threshold change mid-year?

No. The SGA threshold is set each January and stays the same for the entire calendar year. It changes only once per year, based on the national average wage index from the prior year. Social Security announces the new threshold in October or November of the prior year.
