You can work and keep your SSDI check, but your earnings will eventually reduce or stop your benefits

Social Security Disability Insurance (SSDI) does not automatically end when you work. Instead, Social Security uses a series of earnings thresholds and work incentives to let you test your ability to work without losing benefits when ready. The key is understanding which threshold applies to you right now, how much you can earn before your check shrinks, and what happens to your Medicare coverage when you return to work.

In 2024, the first threshold is called Substantial Gainful Activity (SGA). If your monthly earnings stay below the SGA limit, Social Security counts the month as a non-work month and you keep your full check. Once you cross that line, your benefits begin to phase out. But before that happens, you have a grace period called the Trial Work Period (TWP) where you can earn any amount and keep your full benefit check for nine months.

Key Takeaways

  • Your first nine months of work do not reduce your SSDI check, no matter how much you earn — this is the Trial Work Period.
  • After the Trial Work Period ends, you enter the Earnings Test period, where Social Security deducts $1 from your benefit for every $2 you earn above the 2024 SGA limit of $1,550 per month.
  • Medicare continues for 93 months after your Trial Work Period ends, even if your benefits stop completely, so you keep coverage while you work.
  • If your earnings drop back below SGA, your benefits restart automatically without a new process.
  • Work incentives like Impairment Related Work Expenses (IRWE) and Plans to Achieve Self-Support (PASS) can lower your countable earnings and extend your benefits.

The Trial Work Period: Nine months of full benefits no matter what you earn

When you first return to work on SSDI, Social Security gives you nine months where your earnings do not affect your check. This is the Trial Work Period (TWP). During these nine months, you report your work activity to Social Security, but the agency does not count the earnings against your benefit amount. You keep your full monthly check.

A month counts as a work month if you earn more than $970 in 2024 or if you work more than 40 hours in self-employment. You do not have to use all nine months in a row — they can be spread across a rolling 60-month window. For example, if you work three months, stop, then work again six months later, both periods count toward your nine-month total. Once you have used all nine months, the Trial Work Period ends and the Earnings Test begins.

During the Trial Work Period, you must still report your earnings to Social Security. You can do this online through your my Social Security account, by phone, or by mail. Failing to report does not protect your benefits — it only delays the agency's review and can trigger an overpayment later.

The Earnings Test: How your benefits shrink when you earn above SGA

After your nine Trial Work Period months end, Social Security applies the Earnings Test. In 2024, the SGA limit is $1,550 per month. If you earn less than that, your benefits do not change. If you earn more, Social Security deducts $1 from your benefit for every $2 you earn above the limit.

Here is a concrete example: suppose your SSDI check is $1,200 per month and you earn $2,550 in a month after your Trial Work Period ends. You are $1,000 over the SGA limit ($2,550 minus $1,550). Social Security deducts $500 from your check ($1,000 ÷ 2). Your benefit for that month becomes $700.

The Earnings Test continues until one of two things happens: either your benefits stop completely because your earnings are too high, or your earnings drop back below SGA. If your benefits stop, you enter a period called the Extended may be able to access Period (EEP), which lasts 36 months. During the EEP, if your earnings drop below SGA in any month, your benefits restart automatically for that month — no new process needed.

Medicare continues even after your SSDI check stops

One of the most important work incentives is that your Medicare coverage does not end when your SSDI benefits do. After your Trial Work Period ends, you have 93 additional months (just over seven years) of Medicare coverage, even if your earnings are so high that your SSDI check becomes zero. This is called Medicare Continuation Coverage.

During these 93 months, you keep both Medicare Part A (hospital insurance) and Medicare Part B (medical insurance) at no cost to you. You do not have to pay premiums. This means you can work full-time, earn a regular salary, and still have health insurance through Medicare while you are building your work history and income.

After the 93 months end, you can continue Medicare Part B by paying the standard premium, which in 2024 ranges from $174.70 to $609 per month depending on your income. Part A remains free as long as you have worked long enough to be insured. If you lose Medicare and need to regain it, you can do so if your earnings drop below SGA for a full month.

Work incentives that reduce your countable earnings

Social Security offers two main work incentives that lower the amount of earnings counted against your SSDI check: Impairment Related Work Expenses (IRWE) and Plans to Achieve Self-Support (PASS).

IRWE lets you deduct the cost of items or services you need because of your disability to work. Examples include medications, medical equipment, therapy, transportation to work, or personal attendant services. If you spend $300 per month on disability-related work expenses, Social Security subtracts that $300 from your gross earnings before explore the Earnings Test. This can keep you below the SGA limit or reduce the amount deducted from your check. You must document these expenses and show they are necessary because of your disability.

A PASS is a written plan you create with a Social Security work incentives planner to reach a specific work goal — such as starting a business, getting a degree, or becoming self-sufficient. While you are following the PASS, Social Security excludes the income and resources you set aside for that goal from your SSDI calculation. A PASS can extend your benefits for years while you build toward independence. You must have a written agreement with Social Security before you start, and you must report your progress regularly.

What happens if you stop working or your earnings drop

If you stop working or your earnings fall below the SGA limit ($1,550 in 2024), your SSDI benefits restart automatically. You do not need to file a new process or contact Social Security — the agency monitors your earnings reports and restarts your check the month after you fall below SGA.

If you are in the Extended may be able to access Period (the 36 months after your benefits stopped), your benefits restart when ready. If you are past the EEP, you can still restart benefits, but you must contact Social Security to request reinstatement. Social Security will review your medical condition to confirm you are still disabled. This review is usually faster than the original process because your case file already exists.

Keep in mind that if you return to work again after restarting benefits, you do not get a new Trial Work Period. You only have one TWP per disability period. If you have already used your nine months, any future work will be subject to the Earnings Test when ready.

Reporting your earnings and avoiding overpayments

You are required to report your earnings to Social Security every month. The easiest way is through your my Social Security account online, where you can log in and report your monthly income. You can also report by phone at 1-800-772-1213 or by mail using Form SSA-777 (Report of Earnings).

If you do not report earnings and Social Security discovers you were working, the agency will calculate an overpayment — money you received but were not supposed to get. You will have to repay it. Social Security can recover overpayments by reducing your future checks, withholding your tax refund, or taking other collection action. Reporting on time prevents this problem.

Social Security also receives wage reports from your employer through the Social Security Administration's records. If your reported earnings do not match what your employer reports, Social Security will contact you to clarify. It is better to report yourself than to have Social Security discover a discrepancy later.

Self-employment and SSDI in 2024

If you are self-employed, Social Security counts a month as a work month if you earn more than $970 or work more than 40 hours in your business, regardless of profit. This means you can have a business that loses money and still use up your Trial Work Period months.

For self-employment, you report your net profit (income minus business expenses) to Social Security. Business expenses are deducted before the Earnings Test is applied. If you have a PASS in place, you can set aside business income toward your self-employment goal and exclude it from your SSDI calculation.

Self-employed individuals should keep detailed records of hours worked and business income and expenses. Social Security may ask for tax returns, profit-and-loss statements, or other documentation to verify your earnings.

Frequently Asked Questions

Can I work part-time and keep most of my SSDI check?

Yes, if you earn less than $1,550 per month in 2024, your check does not change. If you earn between $1,550 and roughly $3,100, your check will shrink but you will still receive something. The exact amount depends on how far above $1,550 your earnings are. During your first nine months of work (Trial Work Period), you keep your full check no matter what you earn.

What if I work for a few months and then stop?

If your earnings drop below $1,550 in a month, your benefits restart automatically for that month. You do not lose your SSDI status. If you are still within 36 months of when your benefits first stopped, the restart is automatic. If you are past that window, contact Social Security to request reinstatement and they will review your medical condition.

Do I lose Medicare if my SSDI check stops?

No. You keep Medicare for 93 months after your Trial Work Period ends, even if your SSDI check becomes zero. After 93 months, you can keep Medicare Part B by paying the monthly premium. This is one of the strongest reasons to try working while on SSDI.

Can I use my Trial Work Period months all at once or do they have to be spread out?

You can use them however you want within a rolling 60-month window. You could work nine months in a row, or work two months, take a break, work three more months, and so on. The nine months do not have to be consecutive. Once all nine are used, they are gone and you move to the Earnings Test.

What if my disability gets worse while I am working?

Contact Social Security when ready. If your condition worsens and you can no longer work, you can stop working and your benefits will restart. You do not lose your SSDI status because you tried to work. If your condition improves, Social Security may conduct a medical review, but attempting work does not automatically trigger one.
