The Basic Calculation: What Counts as a Trial Work Month

Social Security counts a trial work month when you earn $940 or more in a calendar month (as of 2024; this amount changes each year). The $940 threshold is gross income—what you make before taxes, not what you take home. It does not matter whether you work one day or 30 days in that month; if your earnings reach $940, Social Security counts it as one trial work month.

You get nine trial work months total during a rolling 60-month period. Once you use all nine, your benefits stop, but you enter the Extended Period of may be able to access (EPE), which gives you 36 more months to test your work capacity without losing benefits entirely. Understanding how Social Security counts the months—and what counts as earnings—determines when your benefits actually end.

The $940 figure applies only to trial work months. After your nine months are used, a different earnings rule kicks in: the Substantial Gainful Activity (SGA) limit, which is much higher and determines whether you can keep working without losing benefits altogether. That is a separate calculation, but it matters because trial work months are your runway to reach it.

Key Takeaways

  • A trial work month occurs when you earn $940 or more in a single calendar month; the amount changes yearly and is always gross income before taxes.
  • You have nine trial work months spread across any 60-month rolling period, meaning months do not have to be consecutive.
  • Only earned income counts toward the $940 threshold—not investment income, rental income, gifts, or benefits from other programs.
  • Once you use all nine trial work months, you enter the Extended Period of may be able to access, where a higher earnings limit applies for 36 additional months.
  • Social Security counts the month you report earnings, not the month you receive the payment, so timing of when you get paid matters for which month counts.

What Income Counts and What Does Not

Only earned income counts toward the $940 threshold. Earned income means wages from a job, net profit from self-employment, or royalties from creative work. If you are an employee, Social Security uses your gross wages before deductions. If you are self-employed, they use your net profit after business expenses but before income taxes.

These do not count: investment income (interest, dividends, capital gains), rental income, Social Security benefits you receive, Supplemental Security Income (SSI), workers' compensation, unemployment benefits, gifts, inheritances, or loans. Nor does it count if someone pays you in kind—for example, if an employer gives you free housing instead of wages. Only money you earn through work counts.

If you receive a bonus or back pay in a single month, that entire amount counts toward the $940 threshold for that month. If you earn $500 in regular wages and receive a $600 bonus in the same month, you hit $1,100 and that month counts as a trial work month, even if you only worked a few days.

How the Rolling 60-Month Window Works

Your nine trial work months do not have to be consecutive. Social Security tracks them within a rolling 60-month period, meaning the window moves forward as time passes. If you use three trial work months in 2024, those three stay in your count for 60 months. Once 60 months have passed since the first of those three months, that month drops out of the count and you regain one trial work month to use.

This matters because you can space out your work. You could use two trial work months, stop working for a year, work again and use three more, then take another break. As long as you do not use all nine within any single 60-month span, you keep your trial work months available. Once you use the ninth month, however, your benefits stop at the end of that month, regardless of when the earlier months occurred.

Social Security sends you a notice when you use a trial work month. Keep these notices. They show which months counted and how many you have left. If you disagree with the count, you can request a recalculation, but the notice is your proof of what Social Security recorded.

When the Month Counts: Reporting and Timing

The month that counts is the month you earn the income, not the month you receive the payment. If you work in March but do not get paid until April, March is the trial work month. This matters most for self-employed people and those paid on irregular schedules. If you invoice a client in May but they pay you in June, the month you earned it (May) is what counts.

You report your earnings to Social Security, usually through a form called the Earnings Report or by phone. Social Security asks you to report monthly or when your work situation changes. If you do not report, Social Security may count months based on what your employer reports on your W-2 or what they learn from other sources. Reporting yourself is faster and more accurate because you control the timing.

If you are unsure whether a particular month counts, report the earnings and ask Social Security to clarify. They will tell you whether it crossed the $940 threshold and whether it counts as a trial work month. Getting this right early prevents confusion later when your benefits are about to end.

The Transition from Trial Work Months to Extended Period of may be able to access

After you use your ninth trial work month, your benefits stop at the end of that month. But you do not lose SSDI entirely. You enter the Extended Period of may be able to access (EPE), which lasts 36 months. During the EPE, you can earn up to the Substantial Gainful Activity (SGA) limit without losing benefits.

The SGA limit for 2024 is $1,550 per month for non-blind individuals and $2,590 for blind individuals (these amounts change yearly). If you earn less than SGA in a month during your EPE, you get your full SSDI benefit that month. If you earn SGA or more, you lose your benefit for that month but keep your Medicare coverage. This is very different from trial work months, where you keep your full benefit no matter how much you earn.

After your 36-month EPE ends, you can still work, but you must stay under SGA to keep your benefits. If you go over SGA, your benefits stop and you enter a nine-month Expedited Reinstatement period, during which you can request benefits back if your work does not work out. Understanding this progression helps you plan your work strategy and know when to expect changes to your benefits.

Self-Employment and the $940 Calculation

If you are self-employed, Social Security counts your net profit—revenue minus business expenses—not your gross receipts. If you run a small business and bring in $2,000 in a month but spend $1,200 on supplies and overhead, your net profit is $800. That $800 is what counts toward the $940 threshold, so that month would not count as a trial work month.

Keep detailed records of income and expenses. Social Security will ask for tax returns, profit-and-loss statements, or bank records to verify your net profit. If you cannot document your expenses, Social Security may count your gross income instead, which could push you over the $940 threshold when you thought you were under it. This is one of the most common mistakes self-employed people make during trial work.

If you own a business but do not actively work in it—for example, you own a rental property or a business that runs without your daily involvement—that income does not count as earned income. Only income from work you actually do counts. If you hire a manager to run your business and you take a salary, the salary counts; the business profit does not.

Reporting Errors and What to Do If Social Security Miscounts

Social Security sometimes miscounts trial work months because of reporting delays, employer errors, or confusion about what counts as income. If you believe Social Security counted a month incorrectly, request a detailed breakdown of how they calculated it. Ask for the specific earnings they recorded for each month and which months they counted as trial work months.

Common errors include: counting months where you earned under $940, counting investment or benefit income, or counting a month twice. If you find an error, file a written request for reconsideration with your local Social Security office. Include copies of your pay stubs, tax returns, or other proof of what you actually earned. Social Security has 60 days to respond.

If Social Security stops your benefits based on a miscounted trial work month, you can request a hearing before an Administrative Law Judge. Bring all documentation of your earnings. The judge can order Social Security to reinstate your benefits and pay back benefits if the error is found. Do not assume the count is correct just because Social Security said so; verify it yourself.

Frequently Asked Questions

Do I have to earn exactly $940 or can I earn $939 and not count it as a trial work month?

You must earn $940 or more in a calendar month for it to count. If you earn $939, that month does not count as a trial work month. The threshold is strict: $940 is the minimum. The amount changes each year, so check the current year's limit with Social Security before you plan your work schedule.

If I work part-time one week and earn $1,200, does that use up one trial work month or more?

It uses one trial work month. No matter how much you earn in a month—whether $940 or $5,000—it counts as a single trial work month. The amount does not matter; only whether you crossed the threshold. You keep your full benefit for that month regardless of how much you earned.

What happens if I earn $500 one month and $500 the next month—do those two months combine to count as one trial work month?

No. Trial work months are counted month by month. Each month stands alone. You would need $940 in a single calendar month for it to count. Earnings do not carry over from one month to the next. If you earn $500 in January and $500 in February, neither month counts as a trial work month.

Can I use my nine trial work months all at once or do I have to spread them out?

You can use them however you want within the 60-month rolling window. You could use all nine in nine consecutive months, or spread them over years. Once you use the ninth month, your benefits stop, so the timing is your choice—but the outcome is the same. Many people use them consecutively to test whether they can work full-time before their benefits end.

If I get a raise and my monthly earnings jump from $800 to $1,500, do I suddenly have a trial work month?

Only in the month the raise takes effect. If you earned $800 in March and $1,500 starting in April, April counts as a trial work month (because you earned over $940 that month), but March does not. Each month is evaluated separately based on what you earned that specific month.
