SSDI Sylvee is a work incentive that lets you keep more of your benefits while you test your ability to work

Sylvee (Substantial Gainful Activity Levelized Earnings Exclusion) is a rule that suspends your SSDI benefit check during months when your earnings are high, but does not end your case. Instead of losing benefits gradually as you earn more—the way the standard Trial Work Period works—Sylvee lets you earn without any reduction to your payment in months when you stay under the earnings threshold, then pauses your check only in months when you go over it. Your Medicare coverage continues the whole time.

The name comes from the acronym, but what matters is the practical difference: you are not slowly losing your benefit as you work. You either get the full check or you do not, depending on whether that month's earnings cross the line. This makes it easier to predict your income and plan your budget month to month.

Key Takeaways

  • Sylvee suspends your SSDI check in months when you earn above the substantial gainful activity (SGA) amount, but does not reduce it gradually like other work incentives.
  • Your Medicare coverage stays active during Sylvee, even in months when your benefit is suspended.
  • You must request Sylvee in writing; Social Security does not switch you to it automatically when your Trial Work Period ends.
  • Sylvee lasts for 60 months (five years) as long as you remain disabled and do not earn above SGA for nine months in a row.
  • If you stop using Sylvee or your case closes, you cannot restart it later—the window is one-time only.

How Sylvee differs from the standard Trial Work Period

During your Trial Work Period, you can earn up to a set amount each month (currently $1,050 for 2024, though this changes yearly) without any reduction to your SSDI check. After nine months of Trial Work Period use, your benefit amount stays the same but Social Security begins counting your earnings toward the SGA threshold. Once your average monthly earnings hit SGA—currently $1,550 per month in 2024—your entire benefit stops.

Sylvee works differently. Instead of a gradual phase-out, your benefit is either paid in full or suspended entirely, based on whether you earned above SGA that month. If you earn $1,400 in January, you get your full check. If you earn $1,700 in February, you get no check that month. In March, if you earn $1,300, your check resumes. There is no calculation of averages or gradual reduction—it is month-by-month.

This structure gives you more control and predictability. You can see exactly which months will cost you your benefit, and you can plan around it. For someone testing whether they can sustain work, this can feel less like a trap and more like a genuine trial.

When you can use Sylvee and how to request it

Sylvee becomes available to you after your Trial Work Period ends. You do not automatically move into Sylvee—you must ask for it in writing. Contact your local Social Security office or call 1-800-772-1213 and tell them you want to use the Sylvee work incentive. You can also request it through your My Social Security account online.

You are may be able to access for Sylvee if you are still receiving SSDI, you remain disabled according to Social Security's rules, and you have not already used up your Sylvee period. Once you request it, Social Security will send you a notice confirming the start date and explaining how it works.

The clock on Sylvee runs for 60 months (five years) from the month it begins, but only if you use it. If you go nine months without earning above SGA, your Sylvee period ends and your case may close. If you stop working or stop reporting your earnings, you lose access to Sylvee and cannot restart it later.

How your earnings are counted under Sylvee

Social Security counts your gross earnings—the money you earn before taxes and deductions—in the month you earn it. If you are self-employed, they count your net profit (income minus business expenses). You must report your earnings to Social Security, usually through a form called the Work Activity Report (Form SSA-777-F3).

The SGA threshold changes each year. For 2024, SGA is $1,550 per month for non-blind workers and $2,590 for blind workers. Check with Social Security or About SSDI for the current year's amount before you plan your work schedule.

One important detail: if you earn above SGA in a month, your entire benefit for that month is suspended, but you do not lose your case. Your Medicare continues. When your earnings drop below SGA in a later month, your benefit resumes automatically—you do not have to reapply.

Medicare and Medicaid coverage during Sylvee

Your Medicare Part A and Part B coverage continues without interruption during Sylvee, even in months when your benefit is suspended. This is one of the strongest reasons to use Sylvee instead of letting your case close: you keep your health insurance while you work.

Medicaid coverage depends on your state. Some states tie Medicaid to your SSDI benefit, so if your benefit is suspended in a month, your Medicaid may also suspend. Other states use a separate income test for Medicaid that does not change when your SSDI check is suspended. Contact your state Medicaid office or your local Social Security office to find out how your state handles this.

What happens if you earn above SGA for nine months in a row

If you have nine consecutive months in which your earnings are above SGA, your Sylvee period ends and your SSDI case closes. This is called the "nine-month rule." It is designed to mark the point at which Social Security considers you no longer disabled, because you have shown you can sustain substantial work.

If your case closes, you lose your SSDI benefit and your Medicare coverage (though you may be able to buy into Medicare). You also lose access to Sylvee permanently—you cannot request it again later, even if you stop working.

To avoid this, you need to have at least one month below SGA within any nine-month window. This could mean taking a month off, reducing your hours, or timing your work strategically. Keep track of your earnings and plan ahead if you see yourself approaching nine months above SGA.

Sylvee versus other work incentives

Social Security offers several work incentives beyond Sylvee. The Impairment Related Work Expenses (IRWE) deduction lets you subtract certain disability-related costs from your earnings before Social Security counts them. The Plan to Achieve Self-Support (PASS) lets you set aside income and resources for a specific work goal without it affecting your benefit. Expedited Reinstatement lets you restart your case quickly if you stop working within five years of closure.

Sylvee is simpler than IRWE or PASS because it requires no special forms or plans—you just report your earnings and your benefit is paid or suspended based on the SGA threshold. But it is also more rigid: there is no way to reduce your countable earnings like IRWE does, and there is no way to protect savings like PASS does. If you have significant disability-related work costs or savings goals, another incentive might serve you better. Discuss your situation with a work incentive planning specialist (WIPA) or a benefits planning information (BPAO) counselor, both of whom offer free information.

Frequently Asked Questions

Can I use Sylvee if I am still in my Trial Work Period?

No. Sylvee only becomes available after your nine-month Trial Work Period ends. During the Trial Work Period itself, you use the standard rules: you can earn up to the monthly threshold without any reduction to your benefit. Once those nine months are over, you can request Sylvee.

What if I earn above SGA one month but below it the next—do I lose my case?

No, not unless you have nine consecutive months above SGA. If you earn $1,700 in January and $1,200 in February, you have broken the chain. You can continue using Sylvee as long as you do not have nine months in a row above SGA.

Does Sylvee affect my taxes or my SSI if I also receive it?

Sylvee does not change how your SSDI is taxed. SSDI is taxable income to the IRS if your combined income (SSDI plus other income) exceeds certain thresholds. SSI (Supplemental Security Income) is a different program and has its own rules; you cannot receive both SSDI and SSI at the same time, so this does not explore.

If my Sylvee period ends because I earned above SGA for nine months, can I reapply for SSDI?

You can reapply, but you would have to go through the full process process again and prove you are disabled. You cannot restart Sylvee. If you think your case might close, talk to a work incentive counselor before you reach nine months above SGA.
