Updated August 3, 2026. Quick answer: the trial work period lets you test working without losing Social Security disability benefits. You get nine such months, they do not have to be consecutive, and they are counted inside a rolling sixty-month window. That rolling window is the part people lose track of, and losing track of it is how benefits stop unexpectedly.
What the regulation says
The trial work period is a period during which you may test your ability to work and still be considered disabled… you may perform services in as many as 9 months, but these months do not have to be consecutive… the 9th month…in which you have performed services within a period of 60 consecutive months.
— 20 CFR §404.1592
Three separate mechanics sit in that text, and each one catches somebody out:
- Nine months. Not nine consecutive months, and not nine months per job.
- Not necessarily consecutive. A month in 2023 and a month in 2026 both count if they fall inside the same rolling window.
- Sixty consecutive months. The window rolls. It is not a fresh count each calendar year, and it does not reset because you stopped working for a while.
Why you should keep the count yourself
This is the practical heart of it. Whether a given month counts as a trial work month depends on an earnings amount that is re-set every year, so the same wage can be a service month one year and not the next. Nobody sends you a running total in real time.
Keep a simple record: month, gross earnings, and whether it counted. Twelve lines a year. If you are ever told your trial work period is exhausted, that record is the only thing that lets you check the claim rather than accept it.
What happens after the ninth month
You will be paid benefits for the first month after the trial work period in which you do substantial gainful activity…and the two succeeding months, whether or not you do substantial gainful activity in those succeeding months. After those three months, we will stop your benefits for any month in which you do substantial gainful activity.
— 20 CFR §404.1592a
So it does not stop abruptly at month nine. There is a further period during which benefits are paid for the first month of substantial gainful activity and the two months after it, whatever you earn in those two — and then benefits stop for any month in which you do substantial gainful activity, but can resume in a month you do not, without a new application.
How the earnings threshold is actually set
We are not going to print a dollar figure here, for two reasons: it changes annually, and we could not read the current one from an official source this pass. What we can give you is better, because it does not go stale — the regulation states the formula:
Beginning January 1, 2001, and each year thereafter, they average more than the larger of: The amount for the previous year, or An amount adjusted for national wage growth, calculated by multiplying $700 by the ratio of the national average wage index for the year 2 calendar years before the year for which the amount is being calculated to the national average wage index for the year 1998.
— 20 CFR §404.1574
The $700 in that formula is a fixed base tied to the 1998 national average wage index, not a current threshold. The amount is indexed to national wage growth and ratchets — it is the larger of last year’s amount or the newly computed one, so it does not fall.
And what counts as the activity itself:
Substantial work activity is work activity that involves doing significant physical or mental activities… Gainful work activity is work activity that you do for pay or profit. Work activity is gainful if it is the kind of work usually done for pay or profit, whether or not a profit is realized.
— 20 CFR §404.1572
Where to get the current figure and real help
The current-year amounts are published by the Social Security Administration; ask for them directly rather than relying on any article, including this one. If your benefits have stopped or you have been told you were overpaid, free help exists — legal aid offices, state protection and advocacy organisations, and the Work Incentives Planning and Assistance network all handle exactly this and cost nothing.
Honest gaps
Self-employment is counted differently from wages, by hours as well as income, and we have not covered that. The reentitlement period’s ending point is stated more than one way in the regulation depending on circumstances, and we have described the general shape rather than every variant. Expedited reinstatement after the period ends is not covered.
