SSDI has no official part-time hour limit, but your earnings determine whether you keep your benefits

Social Security does not cap the number of hours you work per week on SSDI. You can work 10 hours a week or 39 hours a week. What matters is how much money you earn in a month, not the clock time you spend working.

Social Security tracks your monthly earnings, not your schedule. If you earn more than the monthly limit, your benefits reduce or stop for that month. The limit changes each year. For 2024, the limit is $1,550 per month while you are still working toward your full retirement age. Once you reach full retirement age, a higher limit applies for months before you turn full retirement age, and no limit applies after.

This means you could work 5 hours a week at $400 per hour and hit the limit when ready, or work 30 hours a week at $40 per hour and stay under it. The structure is designed to let you test whether you can sustain work without losing your safety net.

Key Takeaways

  • SSDI does not restrict how many hours per week you work; only your monthly earnings count toward the limit.
  • If you earn more than $1,550 per month in 2024, Social Security reduces your benefits by $1 for every $2 you earn above that amount.
  • The monthly earnings limit increases each January and varies depending on whether you have reached full retirement age.
  • Work incentives like the Trial Work Period and Extended may be able to access Period let you test employment without losing benefits when ready.
  • You must report your earnings to Social Security every month, even if you think you are under the limit.

How the Monthly Earnings Limit Works

Social Security subtracts $1 from your SSDI check for every $2 you earn above the monthly limit. This is called the earnings test. It is not a cliff where you lose all benefits at one dollar over; it is a gradual reduction.

Example: You earn $2,050 in a month. The limit is $1,550. You are $500 over. Social Security reduces your benefit by $250 that month (half of $500). You still receive your SSDI payment minus $250.

The limit applies only to work earnings—wages from a job, net income from self-employment, or royalties. It does not include retirement income, investment returns, unemployment benefits, or other non-work money. If you receive a one-time bonus or back pay, Social Security counts it in the month you receive it, which can push you over the limit that month only.

The limit is adjusted each year in January. Social Security publishes the new amount in December of the previous year. You can find the current limit on the Social Security website or by calling 1-800-772-1213.

The Trial Work Period: Nine Months to Test Employment

The Trial Work Period is a nine-month window during which you can earn any amount without losing your SSDI benefits. This is the main work incentive built into the program. You do not have to ask permission to use it; it starts automatically the first month you work.

During the Trial Work Period, you report your earnings to Social Security, but they do not reduce your benefits no matter how much you earn. The nine months do not have to be consecutive. If you work in January, take two months off, then work again in April, those are still counted toward your nine months. Only months in which you earn $940 or more (in 2024) count as a Trial Work Period month.

After your nine Trial Work Period months end, you enter the Extended may be able to access Period. For the next 36 months, the earnings test applies again—you lose benefits if you earn over the monthly limit. But if your earnings drop below the limit in any month, your full SSDI payment resumes that month. This gives you a three-year runway to see if you can sustain work before your benefits stop permanently.

What Happens When You Earn Over the Limit

If you earn more than the monthly limit during the Extended may be able to access Period or after it ends, your benefits do not stop when ready. Social Security reduces your payment based on how much you earned that month. If you earn far enough over the limit that your reduction exceeds your full SSDI amount, you receive $0 that month—but you are not removed from the rolls.

Once your Extended may be able to access Period ends (36 months after your Trial Work Period), the rules change. If you earn over the limit in any month, you lose your benefits for that month and all following months until your earnings drop below the limit again for a full month. This is called substantial gainful activity, or SGA. The SGA earnings limit is higher than the regular monthly limit—for 2024, it is $3,822 per month for non-blind beneficiaries.

If you stop work or your earnings drop below the limit, you can request that your benefits restart. Social Security will reinstate you without requiring a new medical review, as long as you request reinstatement within five years of the month your benefits stopped.

Reporting Your Earnings Every Month

You are required to report your earnings to Social Security by the 15th of the month following the month you worked. If you earned money in January, you report it by February 15. Failure to report can result in an overpayment—Social Security will send you a bill for benefits you should not have received.

You can report earnings online through your My Social Security account, by phone at 1-800-772-1213, or by mail. Online reporting is the fastest and creates a record when ready. When you report, have your pay stubs or a record of how much you earned ready.

If you are self-employed, you report your net income (revenue minus business expenses). Keep records of all income and expenses. At the end of the year, you will also file a tax return, and Social Security may cross-check your reported earnings against your tax filing.

Part-Time Work and Your Benefit Amount

Your SSDI payment amount does not change based on how many hours you work. Whether you work 5 hours a week or 35 hours a week, your monthly benefit stays the same—until your earnings trigger the earnings test and reduce it.

The benefit amount is set when you are first approved and is based on your work history and the age at which you became disabled. It does not increase or decrease based on current employment. Only earnings above the monthly limit affect your payment.

This is different from Supplemental Security Income (SSI), which has both an earnings limit and a resource limit. If you receive SSI instead of SSDI, or both, the rules are stricter. SSI counts more types of income and has a lower earnings threshold.

Work Incentives Beyond the Trial Work Period

Social Security offers other work incentives beyond the Trial Work Period and Extended may be able to access Period. The Plan to Achieve Self-Support (PASS) lets you set aside income and resources for a specific work goal without it counting against your benefits. You write a plan, Social Security approves it, and then money you set aside for that goal does not reduce your benefits.

The Impairment Related Work Expenses (IRWE) deduction lets you subtract certain work-related costs from your earnings before the earnings test is applied. If you pay for a personal assistant, medical equipment, or transportation related to your disability, you may be able to deduct those costs. This effectively raises your earnings limit.

A Work Incentives Planning and information (WIPA) project in your state offers free counseling on how to use these incentives. You can find your local WIPA office on the Social Security website. These counselors understand the rules in detail and can help you structure your work and deductions to keep the most benefits.

Frequently Asked Questions

Can I work part-time and keep all my SSDI benefits?

Yes, during your nine-month Trial Work Period, you can earn any amount and keep your full benefit. After that, you can earn up to $1,550 per month (2024) and keep your full benefit. Above that, your benefit reduces by $1 for every $2 you earn over the limit.

What if I work irregular hours and some months earn more than others?

Social Security applies the earnings test to each month separately. A month in which you earn $2,000 will reduce your benefit that month. A month in which you earn $1,200 will not. You report actual earnings each month, so irregular income is handled month by month.

Do I lose my Medicare if I work and my benefits stop?

No. Once you have received SSDI for 24 months, you become may have access to to Medicare regardless of whether you are currently receiving a payment. If your benefits stop because of earnings, your Medicare continues. You must pay the premiums, but coverage does not end.

Can I work more hours if I earn less per hour?

Yes. SSDI does not limit hours worked. If you earn $15 per hour, you can work 100 hours a month and earn $1,500, staying under the limit. If you earn $50 per hour, you hit the limit in 31 hours. Hours are not the constraint; total monthly earnings are.

What if I am self-employed and my income varies month to month?

Report your actual net income each month. If you have a month with low income, your benefit is not reduced that month. If you have a high-income month, the earnings test applies to that month only. Keep detailed records of income and expenses so you can report accurately.
