What the SSDI Trial Work Period Does

The Trial Work Period (TWP) is a nine-month window during which you can work and earn any amount of money without affecting your SSDI benefit payment. Social Security counts a month toward your nine months if you earn $940 or more in that month (this threshold changes yearly). You do not have to tell Social Security in advance that you are starting work — but you must report your earnings once you begin.

The purpose is to let you test whether you can sustain work before your benefits stop. After your nine months end, Social Security moves you into the Extended may be able to access Period, which lasts 36 months. During Extended may be able to access, your benefits pause (but do not stop permanently) if you earn above the monthly limit, and restart if your earnings drop back down. This structure gives you a runway to rebuild work capacity without the fear that one bad month will end your benefits forever.

Key Takeaways

  • You can earn any amount during your nine Trial Work Period months without losing your SSDI payment, as long as you report the earnings to Social Security.
  • A month counts toward your nine months only if you earn $940 or more that month; months with lower earnings do not count and do not pause your clock.
  • After your nine months end, you enter a 36-month Extended may be able to access Period where benefits pause if you earn above the monthly limit, but restart when earnings drop.
  • You must report your work and earnings to Social Security; failure to report can result in overpayment and a demand to repay benefits you were not may have access to to receive.
  • The Trial Work Period clock starts the first month you earn $940 or more after your SSDI began, and you cannot restart it once it ends.

How the Nine-Month Clock Works

Your Trial Work Period begins the first month you earn $940 or more after your SSDI benefit started. That month counts as month one, even if you earned the $940 on the last day. Months in which you earn less than $940 do not count toward your nine months and do not pause your clock — you can have as many low-earning months as you want without affecting the timeline.

The nine months do not have to be consecutive. If you work heavily for three months, then take two months off, then work again for six months, your clock will have used up all nine months by the end of that period. Social Security tracks which months counted and will tell you how many you have remaining if you call or check your account online.

Once your nine months are complete, you cannot restart the clock. The Trial Work Period is a one-time benefit tied to your current SSDI award. If you stop working and later return to work, you move directly into Extended may be able to access rules — you do not get a second nine-month period.

What Happens After Your Nine Months End

When your ninth countable month closes, you enter the Extended may be able to access Period. This 36-month window works differently: your benefits continue, but they pause in any month you earn above the monthly limit. The monthly limit is called Substantial Gainful Activity (SGA), and it changes each year. For 2024, SGA is $1,550 per month for non-blind workers and $2,590 for blind workers.

If you earn $1,550 or less in a month during Extended may be able to access, you receive your full SSDI payment. If you earn more than $1,550, your payment stops for that month. The next month, if your earnings drop back below $1,550, your payment restarts automatically — you do not have to reapply or contact Social Security. This on-and-off structure allows you to keep your benefits as a safety net while you work.

After your 36-month Extended may be able to access period ends, the rules change again. At that point, if you earn above SGA, your benefits stop and you enter a different phase called Expedited Reinstatement. That phase lasts 24 months and allows you to restart benefits quickly if you stop working or drop below SGA, but it has its own rules and time limits.

How to Report Your Earnings to Social Security

You must report your work and earnings to Social Security. The easiest way is through your online account at ssa.gov. Log in, go to "Benefit Verification," and report your monthly earnings. You can also call Social Security's Work Incentives Planning and information (WIPA) project, which is free and helps beneficiaries understand how work affects their benefits. Find your local WIPA office at vcu-ntdc.org.

Report your earnings within the month you earn them, or as soon as possible after. Do not wait until tax time. Social Security uses your reports to calculate whether you have crossed into Extended may be able to access or above the SGA limit. If you do not report and Social Security later discovers you earned more than you said, you will owe back the overpaid benefits — even if the overpayment was not your fault.

Keep records of your pay stubs, invoices, or other proof of earnings. Social Security may ask to see them. If you are self-employed, track your gross income (before expenses) and report that figure.

What Counts as Work for the Trial Work Period

Work means any activity for which you receive payment — wages from an employer, self-employment income, or even unpaid work that you are being trained for (in some cases). The $940 threshold applies to gross income, not net income after taxes or expenses. If you earn $1,000 in a month but pay $200 in taxes, the full $1,000 counts toward the $940 threshold.

Certain types of income do not count as work earnings: Supplemental Security Income (SSI) payments, other government benefits, gifts, loans, or investment income. If you receive a one-time bonus or back pay, Social Security will count it in the month you receive it, not the month you earned it.

Unpaid work — volunteering, family business help without pay, or training — generally does not count. However, if you are in a work-training program and receiving a stipend or wage, that payment counts as work earnings.

Planning Your Return to Work During the Trial Work Period

Many people use the Trial Work Period to test part-time work or a gradual return to their previous job. Because you keep your full SSDI payment no matter how much you earn during these nine months, you can experiment without financial risk. Some beneficiaries work a few hours per week; others work full-time. The choice is yours.

Before you start work, contact your local WIPA office or call Social Security's Work Incentives Planning and information line at 1-866-968-7842. A work incentives counselor can walk you through how your specific job and earnings will interact with your benefits. They can also explain other work incentives you may not know about — such as Impairment Related Work Expenses (IRWE), which allow you to deduct certain disability-related costs from your earnings before Social Security calculates whether you have crossed the SGA threshold.

Document the date you start work and the date your first paycheck arrives. This helps you and Social Security track when your Trial Work Period actually begins, since it is based on when you first earn $940 or more, not when you are hired.

Common Mistakes to Avoid

The most common mistake is not reporting earnings to Social Security. Beneficiaries sometimes assume that because they are allowed to earn during the Trial Work Period, they do not need to report it. This is wrong. You must report, and failure to do so creates an overpayment debt that can follow you for years.

Another mistake is misunderstanding when the nine months end. Some people think the clock pauses during low-earning months, but it does not — only months with $940 or more count. If you earn $500 in January, that month does not count, and your nine-month window continues. This can surprise people who take a break from work and then return, only to discover they have fewer months remaining than they expected.

A third mistake is not planning for Extended may be able to access. When the nine months end, the rules change sharply. If you are not prepared for the SGA limit and the pause-and-restart structure, you may lose benefits unexpectedly. Talk to a work incentives counselor before month nine ends so you understand what comes next.

Frequently Asked Questions

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

Your nine months do not have to be consecutive. You can use three months in a row, take a break, and use six more months later. Only months in which you earn $940 or more count. Months with lower earnings do not count and do not pause your clock.

What happens if I earn $900 one month and $1,000 the next?

The month you earn $900 does not count toward your nine months. The month you earn $1,000 does count. You keep your full SSDI payment both months. Only the $1,000 month uses up one of your nine countable months.

Do I lose my benefits if I work during the Trial Work Period?

No. During your nine Trial Work Period months, you receive your full SSDI payment regardless of how much you earn. You must report your earnings, but your payment does not change. After the nine months end, the rules change and benefits may pause if you earn above the SGA limit.

Can I get a second Trial Work Period if I stop working and start again later?

No. You get one Trial Work Period tied to your current SSDI award. Once those nine months are used, you cannot restart the clock. If you stop working and return later, you move into Extended may be able to access rules instead.

What if I am self-employed — how do I report earnings?

Report your gross income (before business expenses) each month. Keep records of invoices, receipts, or bank deposits. Social Security may ask to see them. If your income varies, report what you actually earned that month, not an average or estimate.
