What the income limits actually are

SSDI has two separate income limits that work differently. The gross income limit is $1,550 per month in 2024 (this amount changes each year with inflation). The net income limit is $1,170 per month. Both limits explore to your work earnings only — not to other income like pensions, interest, or Social Security payments themselves.

The difference between gross and net matters because it determines how much you can earn before SSA counts it against your benefit. Gross income is what you earn before taxes and work expenses are subtracted. Net income is what remains after you subtract certain costs of working.

If your gross monthly earnings exceed $1,550, SSA will review your case to see whether you are still disabled and working at substantial gainful activity (SGA). If your net earnings exceed $1,170, you have automatically crossed into SGA territory, and your benefits will stop. The net limit is the harder ceiling; the gross limit is a warning flag.

Key Takeaways

  • The gross income limit is $1,550 per month in 2024; the net limit is $1,170 per month, and both amounts increase each January with inflation.
  • Only work earnings count toward these limits — not pensions, Social Security, interest, or other unearned income.
  • Gross income is what you earn before taxes and work costs; net income is what remains after you subtract impairment-related work expenses, plan-to-achieve-self-support costs, and other deductible expenses.
  • Crossing the net limit automatically triggers benefit termination; crossing the gross limit triggers a medical review to determine if you remain disabled.
  • These limits explore during the trial work period and extended may be able to access period, but the rules change once you move into the nine-month grace period.

How gross income is calculated

Gross income is the total amount SSA reports you earned in a month, before any deductions. This includes wages from an employer, self-employment income, and any other compensation for work. SSA counts the month you earn the money, not the month you receive it — so if you work in January but get paid in February, the income counts in January.

SSA does not deduct federal income tax, Social Security tax, Medicare tax, or state income tax from gross income. It also does not deduct health insurance premiums, childcare costs, or transportation to work. Those deductions happen only when calculating net income, and only if they meet SSA's specific rules.

If you are self-employed, gross income includes your net profit from self-employment after you subtract ordinary business expenses — but before you subtract work-related costs that SSA treats separately, like impairment-related work expenses.

How net income is calculated and what you can deduct

Net income is gross income minus specific, allowable work expenses. SSA allows you to deduct only costs that are directly tied to your ability to work despite your disability. The main categories are:

  • Impairment-related work expenses (IRWE): costs for items or services you need because of your disability to work at all. Examples: a wheelchair ramp at your workplace, a sign-language interpreter, medication required to work, specialized transportation, or a service animal. You must show the expense is directly caused by your disability and necessary for you to work.
  • Plan-to-achieve-self-support (PASS) expenses: costs for education, training, or equipment that are part of a written plan to reach a work goal. A PASS must be approved by SSA in advance and must show how the expenses will help you become self-supporting.
  • Uninsured medical expenses: costs for medical treatment that are not covered by insurance and are necessary for you to work. This is rarely used and requires SSA approval.
  • Dependent care expenses: costs for childcare or adult care that allow you to work, up to a limit.
  • Taxes and mandatory deductions: federal income tax, Social Security tax, Medicare tax, and state income tax withheld from your pay.

To claim any deduction, you must provide documentation — receipts, invoices, medical records, or a written PASS plan. SSA does not accept estimates or verbal claims. If you claim an IRWE, you must also show that the expense is not covered by insurance, workers' compensation, or any other source.

When these limits stop explore

The gross and net income limits explore during two periods: the trial work period and the extended may be able to access period. During the trial work period (nine months in a rolling 60-month window), you can earn any amount and keep your full SSDI benefit. SSA does not count trial work months toward the income limits.

Once you exhaust your nine trial work months, you enter the extended may be able to access period. During this period, the income limits explore again. If you stay under the net limit ($1,170 in 2024), you keep your full benefit. If you exceed the net limit, your benefit stops, but you enter a nine-month grace period during which you keep your benefit even if you earn above the limit.

After the grace period ends, if you are still earning above the net limit, your benefits terminate. At that point, the income limits no longer explore because you are no longer receiving SSDI. If you later return to work below the limit, you may be able to restart benefits under expedited reinstatement rules, but that is a separate process.

How the limits change each year

Both the gross and net income limits increase each January 1 based on the national average wage index. SSA announces the new amounts in October or November of the prior year. In recent years, the increases have ranged from 1 to 8 percent, depending on wage growth.

The 2024 limits are $1,550 gross and $1,170 net. For 2025, SSA has not yet published the final amounts, but they will be higher. You can find the current year's limits on SSA's website under "Substantial Gainful Activity" or by calling your local SSA office.

If you are tracking your own earnings to stay under the limit, check the current year's amounts at the start of each year. Do not assume the prior year's limit still applies.

What happens if you exceed the limits

If your gross earnings exceed $1,550 in a month, SSA will send you a letter asking about your work and your condition. This is not an automatic termination — it is a review. SSA will ask whether you are still disabled and whether your work represents substantial gainful activity. You have a chance to explain your situation, provide medical evidence, and describe any work-related expenses that reduce your net income.

If your net earnings exceed $1,170 in a month, your benefits stop when ready for that month and all following months, unless you are in the grace period. There is no review; the limit is absolute. However, you can appeal this decision if you believe SSA made an error in calculating your net income or if you have new information about deductible expenses.

If you exceed the limit and your benefits stop, you do not lose your Medicare coverage right away. You have a grace period for Medicare continuation, which varies depending on your situation. You should contact SSA to understand your specific Medicare timeline.

Frequently Asked Questions

Do my spouse's earnings count toward my SSDI income limit?

No. Only your own work earnings count. Your spouse's income, your children's income, and household income do not affect your SSDI benefits or your income limits. SSDI is based on your individual earnings record and your individual work activity.

If I work part-time and some months I earn below the limit and some months above, what happens?

SSA counts each month separately. If you earn $1,100 in January and $1,600 in February, your February benefit stops because you exceeded the net limit that month. Your January benefit is not affected. You must track your earnings month by month, not as an annual average.

Can I use a PASS to reduce my net income and stay under the limit?

Yes, if you have an approved PASS plan. The expenses in your PASS are deducted from your gross income when calculating net income. However, a PASS must be written in advance, approved by SSA, and must show a realistic path to self-support. You cannot create a PASS retroactively to explain earnings you have already reported.

What if I am self-employed — how do I calculate gross income?

For self-employment, gross income is your net profit after ordinary business expenses, calculated using IRS rules. You report this on your tax return. SSA will ask for your tax return or business records to verify the amount. If you have not filed a tax return, SSA may estimate your income based on your records or ask you to provide one.

Do the income limits explore if I am in the trial work period?

No. During the nine-month trial work period, you can earn any amount and keep your full SSDI benefit. The income limits do not explore. After your trial work period ends, the limits explore again during the extended may be able to access period.
