You can work part-time while collecting SSDI, and in 2026 you keep your full benefit as long as your countable monthly earnings stay under $1,690, the Social Security Administration’s substantial gainful activity limit. Before that ceiling even applies, you get a nine-month trial work period with no earnings cap at all, followed by a three-year window where benefits switch on or off month by month depending on what you earn. Working part time on SSDI is not only allowed; the program is built around letting you try.
The 2026 Earnings Limit
Substantial gainful activity, or SGA, is the line SSA draws between limited work and “real” employment. For 2026, the monthly SGA figure is $1,690 for most beneficiaries and $2,830 for people who are blind.1Social Security Administration. Substantial Gainful Activity
The number that matters is countable earnings, not gross pay. SSA subtracts several categories of expense before comparing your income to SGA, so a paycheck that looks like it crosses the line on paper may still fall under it once the deductions are applied.
Your Nine-Month Trial Work Period
The trial work period is a risk-free test run. For nine months, you receive your full SSDI check no matter how much you earn. There is no cap during this window. A well-paying part-time job pays you and SSA pays you.2Choose Work! Trial Work Period (TWP)
A month only uses up part of the trial if your pre-tax earnings hit $1,210 or more in 2026. If you are self-employed, working more than 80 hours in a month also counts, regardless of what you earned. The nine months don’t need to be consecutive: they accumulate across a rolling 60-month window, so you can use a few, take a break, and use the rest later.3Ticket to Work – Social Security. Fact Sheet – Trial Work Period 2026
Many part-time workers never burn through all nine months, because low-earning or low-hour months simply don’t count.
What Happens After the Trial Ends
Once you’ve used all nine trial months, the extended period of eligibility begins the very next month and runs for 36 months. During those three years, SSA looks at each month on its own. Earn below SGA that month and your check arrives. Earn at or above SGA and your check is suspended for that month only.4Social Security Administration. SSDI Only Employment Supports
The first time your earnings cross SGA in this period, SSA formally decides your disability has “ceased” due to work. That sounds worse than it is: a three-month grace period follows, and you receive full benefits for the cessation month and the two months after it even if you are still earning above SGA.5Social Security Administration. POMS DI 13010.210 – Extended Period of Eligibility (EPE) – Overview
After the grace period, the month-by-month on-off pattern continues for the rest of the 36 months. This is genuinely useful for part-time workers whose hours fluctuate. The real risk point is at the end of the window: if you’re earning above SGA in any month after the 36 months expire, your benefits terminate.5Social Security Administration. POMS DI 13010.210 – Extended Period of Eligibility (EPE) – Overview
Deductions That Can Keep You Under SGA
Three categories of deduction can pull your countable earnings below the SGA line even when your paycheck looks higher.
Impairment-Related Work Expenses
Costs you pay out of pocket for items or services you need because of your disability in order to work are subtracted from your earnings before SSA applies the SGA test. The expense has to relate to your impairment and be necessary for you to do your job, but it doesn’t have to be used only at work. A hearing aid you also wear at home still qualifies if you need it for workplace communication.6Choose Work! Ticket to Work – Work Incentives Series – Impairment-Related Work Expenses
Expenses that commonly qualify include disability-related vehicle modifications that let you commute, service animals (purchase, training, food, and veterinary care), prosthetics and medical devices needed for the job, specialized transportation when you can’t drive yourself, and medications that control symptoms enough for you to work. The full amount is deducted; SSA does not prorate between work and personal use.7Social Security Administration. POMS DI 10520.030 – Determining When IRWE Are Deductible
Subsidies and Special Conditions
If your employer pays you more than the work you actually perform is worth, SSA can treat the difference as a subsidy and exclude it from your earnings. This often applies when a coworker handles part of your duties, when you receive extra supervision, or when a job coach assists you. SSA determines the real value of your contribution and counts only that toward SGA.8Social Security Administration. Subsidy and Special Conditions
Unsuccessful Work Attempts
If you start a job but have to stop or drop below SGA within six months because of your disability, SSA can classify that stretch as an unsuccessful work attempt. Earnings during it don’t count against you. The work must have lasted six months or less, ended or dropped below SGA because of your impairment, and been preceded by a significant break from prior work activity.9Social Security Administration. POMS DI 11010.145 – Unsuccessful Work Attempt (UWA) Overview
Health Coverage While You Work
After your trial work period ends, your premium-free Medicare Part A coverage continues for at least 93 consecutive months, which is seven years and nine months. This protection applies as long as you still have a disabling impairment, even in months when your cash benefit is suspended because you earned too much.10Social Security Administration. Medicare Information
If the 93 months run out and you’re still working, you can buy Medicare Part A at the same premium uninsured retirees pay. A state assistance program may help cover the premium if your income is limited and you still have a disabling condition. Most states also run Medicaid Buy-In programs that let workers with disabilities keep Medicaid even when earnings exceed the usual eligibility limits.11Medicaid.gov. Ticket to Work
Reporting Your Earnings
You have to report all work activity to SSA promptly: when you start a job, when you stop, and any change in hours or pay. Failing to report is the fastest way to trigger an overpayment, where SSA pays you money you weren’t entitled to and then bills you for it back. Reporting can be done through your online my Social Security account, by phone at 1-800-772-1213, by mail, or in person at a local office.12Social Security Administration. Spotlight on Reporting Your Earnings to Social Security
Report as soon as things change, not at tax time. An overpayment caught early is a few hundred dollars. An overpayment that runs unreported for a year can be devastating.
If You Get an Overpayment Notice
SSA will send a notice with the amount owed and a repayment plan. You can request a waiver using Form SSA-632 by showing the overpayment wasn’t your fault and that repaying would cause financial hardship or be unfair. There is no deadline for filing a waiver, and SSA stops collecting while it reviews your request. For overpayments of $1,000 or less, the waiver process can often be handled by phone.13Social Security Administration. Overpayments
Getting Benefits Back If Work Doesn’t Last
Even after benefits terminate because of work, there is a five-year safety net. If your disability prevents you from continuing to work at the SGA level within 60 months of termination, you can request expedited reinstatement without filing a new disability application. The impairment has to be the same as, or related to, your original condition.14Social Security Administration. POMS DI 13050.001 – Expedited Reinstatement (EXR) Overview
While SSA reviews the request, you can receive up to six months of provisional cash benefits and Medicare coverage. If reinstatement is ultimately denied, you generally don’t have to repay provisional benefits received in good faith.15Social Security Administration.

Ticket to Work and Protection From Medical Reviews
Ticket to Work is a free, voluntary SSA program that connects SSDI beneficiaries with job training, career counseling, and placement assistance through approved providers.16Social Security Administration. Welcome to the Ticket to Work Program!
The important protection sits alongside the vocational help: if you assign your ticket before a medical continuing disability review has been scheduled, SSA won’t conduct that review while you are actively participating and making timely progress. Testing part-time work won’t itself put you in front of a doctor who might find you no longer disabled.17Choose Work! Ticket to Work Dictionary
