Trying work again on SSDI — the nine months, the safety net, and the deductions nobody claims

The fear that stops people trying is always the same: if I take a job and it does not work out, I have thrown away the benefit that took two years to win.

Social Security has built an entire structure to answer that fear. It is set out in a publication called the Red Book, and it is one of the least-read useful documents in the federal government. This page walks through the parts that matter if you have Parkinson’s and are thinking about work — whether that is going back, cutting down, or trying something different.

All figures are 2026 figures, checked against the Red Book in August 2026. They change each January.

The 2026 numbers you need

Note the gap between $1,210 and $1,690. Earning $1,400 uses up a trial work month but is not substantial gainful activity. That distinction runs through everything below.

Nine months where earnings do not matter at all

The Trial Work Period (TWP) is the first and most generous protection.

The TWP allows you to test your ability to work for at least 9 months. During your TWP, you will receive full Social Security Disability Insurance (SSDI) benefits. You will receive them regardless of how high your earnings might be if you report your work activity, and you have a disabling impairment.

Read that literally, because it is meant literally. Regardless of how high your earnings might be. For nine months you can earn anything and still receive the full SSDI payment.

The mechanics:

• A month counts as a trial work month only if your gross earnings exceed $1,210 in 2026, or you work more than 80 hours in self-employment.
• The nine months do not have to be consecutive. They are counted within a rolling 60-month window.
• Your TWP cannot begin before the first month you are entitled to SSDI, or the month you filed, whichever is later.
• Unsuccessful work attempts do not apply during the TWP — every qualifying month counts, even one you had to abandon.

Two warnings. Social Security “can consider medical evidence that might demonstrate your medical recovery at any time,” so benefits can end for medical reasons regardless of the TWP. And if you worked at SGA level within 12 months of your impairment starting and before your claim was approved, you were never eligible in the first place.

After the nine months: 36 more of on-and-off protection

The Extended Period of Eligibility (EPE) begins the month after the TWP ends, whether or not you are working. Its first 36 months are the re-entitlement period, and it works like a switch rather than a cliff.

• In any month your earnings are below SGA, you get paid, provided you still have a disabling impairment.
• In any month your earnings are above SGA, cash benefits are suspended.
• If earnings drop back below SGA inside the 36 months, “we can start your benefits again” — no new application.

The first time you work above SGA during the EPE, Social Security decides your disability has “ceased” — but pays you for that month and the following two. That is the grace period, and it exists so a first good month does not become an immediate loss of income.

What happens at the end depends on where you are:

• Not working above SGA in month 37 → benefits continue until you do work a month at SGA, or you medically recover.
• Working above SGA after the 36 months → benefits end. But see Expedited Reinstatement below, which covers you for another five years.

This structure fits Parkinson’s unusually well. A condition with good stretches and bad ones is exactly what a switch that flips both ways is for.

Medicare keeps going for 93 months

This is the protection people are most relieved to hear about.

Most individuals with disabilities who are working will continue to receive Medicare coverage for at least 93 consecutive months (7 years and 9 months) following the 9-month Trial Work Period.

That is Part A at no premium, plus Part B and Part D if you are enrolled in them. The 93 months start the month after your last TWP month. To qualify you must already have Medicare, your cash benefits must have stopped because of work above SGA, and you must still have a disabling impairment.

And when the 93 months run out, coverage does not simply vanish. You can buy Medicare — Part A at $565 a month in 2026, or $311 with the 45% reduction if you have 30 or more quarters of coverage (or qualify through a spouse), and Part B at $202.90. A Medicare Savings Program may pay those premiums for you; the QDWI program exists specifically for people who lost premium-free Part A by going back to work. Our page on Medicaid and HCBS waivers has the 2026 limits.

The deductions almost nobody claims

Before Social Security decides whether your earnings are above SGA, several things come off the top. Each one can be the difference between keeping a benefit and losing it.

Impairment-related work expenses (IRWE)

Social Security deducts the cost of items and services you need in order to work, from your gross earnings, when it decides whether your work is SGA. Crucially, “it does not matter if you also use these items and services for non-work activities.”

Four conditions: the item enables you to work, you need it because of an impairment, you pay for it and are not reimbursed, and the cost is reasonable for your community.

What counts, from Social Security’s own table, with the Parkinson’s-relevant entries picked out:

• Transport you need because of the disability — driver assistance, taxis, paratransit, special bus. Also structural or operational modifications to your vehicle, even if you use the vehicle for other things. Mileage to and from work for an approved vehicle.
• Attendant care — services in the work setting, and services to help you get ready for work, on the trip, and afterwards: “bathing, dressing, cooking, and eating.” Even services performed by a family member for a cash fee, if they suffer an economic loss by cutting their own hours to help you.
• Medical devices — wheelchairs and braces are named.
• Prescription drugs and medical services for regularly prescribed treatment “necessary to control your disabling condition, even if control is not achieved” — explicitly including copayments and insurance deductibles, and physician fees relating to those services.
• Residential modifications, if you work outside the home, to the exterior: ramps, railings, pathways. If you are self-employed at home, interior modifications to create a workspace.
• Assistive technology used for employment — software, computer support, special tools designed around your impairment.

What does not count: the vehicle itself, cosmetic modifications, routine physicals and dental checks, health insurance premiums, exercise equipment without a physician’s verification, and services on non-workdays or general housekeeping.

For someone with Parkinson’s who pays for medication copays, adapted transport and help getting ready in the morning, IRWE is often thousands of dollars a year of earnings that Social Security simply does not count.

Subsidies and special conditions

If you are paid more than the actual value of the work you do, Social Security counts only the real value. A subsidy may exist when:

• you get extra help, supervision or a job coach to complete your duties,
• you are assigned fewer or easier duties than the job description requires,
• you have a special relationship with the employer, or
• you take additional breaks or time off as an accommodation.

That fourth one describes a great many people with Parkinson’s who have negotiated workplace adjustments. Those adjustments may reduce the earnings Social Security counts. Say so.

Unsuccessful work attempts

If you try work and have to stop, or drop below SGA, within six months because of your disability or because you lost the extra help you needed, those earnings are not counted in the SGA decision. This applies during the EPE, not during the TWP.

Unincurred business expenses

For self-employment, contributions others make to your business — a computer from a vocational rehabilitation agency, unpaid help from a friend — are deducted from net earnings for the SGA decision, even though you never paid for them.

If it does not work out: Expedited Reinstatement

The safety net at the end. If your benefits ended because of work and earnings, and you stop working within five years, you can ask for Expedited Reinstatement rather than filing a new claim.

• You get up to six months of provisional cash benefits while Social Security reviews the case, and may be eligible for Medicare or Medicaid during that period.
• Your current impairment must be the same as, or related to, the original one.
• You must be unable to perform SGA in the month you apply, for medical reasons.

If reinstated, you enter a 24-month initial reinstatement period, and once that is complete you get the whole structure back from the start: a new nine-month trial work period, a new 36-month extended period of eligibility, a new five-year window for another EXR request, and a new period of extended Medicare.

Ticket to Work, and the free help that comes with it

Ticket to Work is Social Security’s voluntary employment program. It connects you to an Employment Network or a State Vocational Rehabilitation agency for career counselling, vocational rehabilitation, job placement and training — all free.

Who qualifies is broader than most people assume: everyone aged 18 through 64 who receives SSDI or SSI because of a disability is eligible, and participation “is free and voluntary.” Social Security no longer mails paper Tickets and you do not need one; your provider verifies eligibility, or you can check it on the help line.

The reason to know about it is not the job search. It is this line in the Red Book:

We will not conduct a continuing disability review if you are participating in the Ticket to Work program, and you are actively working on your employment goal with your Ticket provider.

A continuing disability review is the medical re-examination that can end a benefit. Active participation in Ticket to Work pauses it.

There is also Section 301: if Social Security decides your disability has ended because of medical improvement while you are participating in an approved vocational rehabilitation program that began before that finding, your payments may continue until the program ends.

Four free services are worth calling before anything else, all reachable on 1-866-968-7842 (TTY 1-866-833-2967) or at choosework.ssa.gov/findhelp:

One more thing to ask for by name: a Benefits Planning Query (BPQY). It is a free report on the status of your benefits, scheduled medical reviews, health insurance and work history — Social Security calls requesting one “the first step in planning a successful return to work.” Call 1-800-772-1213. With a signed SSA-3288 consent form, they will share it with your benefits counselor.

The single biggest mistake

Not reporting the work. Every protection on this page assumes Social Security knows what you are earning. Unreported earnings turn into an overpayment notice years later, for a sum that has grown the whole time — and the work incentives cannot be applied retroactively to money that was never declared.

Report when you start, report changes, and keep copies of what you sent and when.

Before you take the job

If this applies to you

Figures are 2026 calendar-year figures checked in August 2026 and change each January. This page does not decide your case. Before acting, get a Benefits Planning Query and free counselling from a WIPA provider — the arithmetic is individual, and the cost of guessing is an overpayment notice.
