Income limits exist, but they work differently than you might expect

Social Security Disability Insurance (SSDI) has no income limit. You can earn money and still receive your full benefit check each month. The program measures disability based on your medical condition and work capacity, not on how much money you have coming in.

Supplemental Security Income (SSI), by contrast, does have strict income and resource limits. If you receive SSI and earn too much, your benefit shrinks or stops. But even SSI has built-in work incentives that let you keep more of your earnings than the basic rules suggest.

The confusion arises because SSDI and SSI are separate programs with separate rules. Which one you receive—or whether you receive both—depends on your work history and age, not on your current income.

Key Takeaways

  • SSDI has no income limit; you can work and earn money without losing your benefit.
  • SSI counts your income and resources against strict limits, but work incentives let you exclude certain earnings and keep more of what you make.
  • The Plan to Achieve Self-Support (PASS) lets SSI recipients set aside income and resources for a work goal without losing benefits.
  • SSDI recipients can test their work capacity under the Trial Work Period, which lets you earn any amount for nine months without losing benefits.
  • Reporting changes in income to Social Security is required; failure to report can result in overpayments you must repay.

How SSDI treats income and earnings

SSDI does not reduce your monthly benefit based on how much you earn. You can work part-time, full-time, or start a business and still receive your full SSDI check. Social Security's only concern is whether your work shows you are no longer disabled.

This is where the Trial Work Period (TWP) comes in. For nine months within a rolling 60-month window, you can earn any amount without Social Security questioning whether you remain disabled. The months do not have to be consecutive. If you earn over the current Substantial Gainful Activity (SGA) threshold—which is $1,550 per month in 2024, though this amount changes yearly—Social Security will review your case to see if your condition has improved enough that you are no longer disabled.

After your Trial Work Period ends, you enter the Extended Period of may be able to access (EPE), which lasts 36 months. During this time, you keep your benefit in any month you earn below the SGA threshold. If you earn above it, you lose that month's benefit, but you do not lose your coverage. Once the EPE ends, you can request reinstatement if you become unable to work again within five years.

How SSI treats income and resources

SSI counts nearly all income against your benefit. The program allows you to exclude the first $65 of monthly earnings plus half of what you earn above that. So if you earn $200 a month, Social Security counts $67.50 against your benefit ($200 minus $65, divided by two, equals $67.50). Your SSI check shrinks by that amount.

SSI also has a resource limit. You can own no more than $2,000 in countable resources if you are single, or $3,000 if you are married. Resources include cash, bank accounts, stocks, and vehicles over a certain value. Your home and one vehicle do not count. If your resources exceed the limit, you lose SSI entirely until you spend down to the threshold.

These limits have not changed since 1989, so they affect far more people now than they did when SSI began. Many SSI recipients live in poverty because the income exclusion and resource limits are so low.

Work incentives that let you keep more earnings

Social Security built several work incentives into both SSDI and SSI to encourage people to test their work capacity without losing all their benefits at once.

The Plan to Achieve Self-Support (PASS) is the most powerful tool for SSI recipients. A PASS lets you set aside income and resources for a specific work goal—starting a business, getting training, buying equipment—without those funds counting against your SSI limits. You write a plan with a Social Security work incentives planner, and for the months you are following it, the set-aside money does not reduce your benefit. PASS plans typically last two to five years. Once you reach your goal and earn enough to support yourself, your SSI ends, but you have built a path to independence.

The Impairment Related Work Expenses (IRWE) deduction applies to both SSDI and SSI. If you have costs directly tied to your ability to work—a personal assistant, medication, medical equipment, transportation—you can deduct them from your countable earnings. This lowers the amount Social Security counts against your benefit.

SSDI recipients also have access to Expedited Reinstatement. If you return to work, lose your benefits because you earn too much, and then become unable to work again within five years, you can get your benefits back without going through the full disability information process again.

What happens when you earn over the income threshold

For SSDI, earning over the SGA threshold does not automatically end your benefits. Social Security will review your case to determine whether your work shows you have medically improved. If you are still disabled but working despite your condition, you keep your benefits. If Social Security concludes you are no longer disabled, your benefits stop, but you enter the Extended Period of may be able to access, which protects you for 36 more months.

For SSI, exceeding the income limit reduces your benefit dollar-for-dollar (after the $65 exclusion and 50% deduction). If your income is high enough, your SSI payment becomes zero, but you keep Medicaid in most states. You do not lose your SSI status; you straightforward receive no cash payment that month.

In both cases, you must report your earnings to Social Security. If you do not report and Social Security discovers the unreported income, you will owe back the benefits you should not have received. These overpayments can be substantial, and Social Security will ask you to repay them, sometimes by reducing future benefits.

Income from sources other than work

SSI counts unearned income—such as child support, alimony, gifts, or money from family members—against your benefit at a dollar-for-dollar rate after a $20 monthly exclusion. So if you receive $100 in gifts, Social Security counts $80 against your SSI.

SSDI does not count any income against your benefit, earned or unearned. You can receive Social Security retirement benefits, pension income, or gifts without affecting your SSDI check.

Some income sources are excluded entirely. For SSI, this includes the first $20 of any unearned income per month, food and shelter provided by others (up to a limit), and certain in-kind support. Work incentives like PASS and IRWE also create exclusions. The rules are detailed, and what counts as income varies by source, so it is worth asking a Social Security work incentives planner to review your specific situation.

Reporting income changes to Social Security

You are required to report changes in your income to Social Security within 10 days. This includes starting a job, getting a raise, losing a job, or receiving a one-time payment. The easiest way to report is through your online my Social Security account, by phone at 1-800-772-1213, or in person at your local Social Security office.

If you receive SSI, you must also report changes in your living situation, household composition, and resources. These changes affect your benefit calculation. Failure to report is considered fraud, even if the unreported income was small or you did not realize you had to report it.

Many people do not report because they fear losing benefits or do not understand the reporting rules. This is understandable, but unreported income creates a debt. If Social Security discovers it later—through tax records, employer reports, or a review—you will owe the full amount back. It is better to report and understand how the work incentives reduce the impact on your benefit.

Frequently Asked Questions

Can I work full-time and keep my SSDI?

Yes. SSDI has no income limit. You can work full-time and earn any amount without losing your benefit, as long as your work does not show that you are no longer disabled. If you earn over the SGA threshold ($1,550 in 2024), Social Security will review your case, but you may still keep your benefits if you remain disabled.

What is the income limit for SSI?

SSI counts income against your benefit after excluding the first $65 of earnings per month and half of earnings above that. There is no hard income limit; your benefit straightforward shrinks as you earn more. For unearned income like gifts, the first $20 per month is excluded, then the rest counts dollar-for-dollar.

If I start working, will I lose my Medicaid?

SSDI recipients keep Medicare regardless of work or income. SSI recipients keep Medicaid in most states even if their cash benefit becomes zero due to earnings. Some states have work incentive programs that extend Medicaid further. Ask your state Medicaid office or a Social Security work incentives planner about your state's rules.

How do I report my earnings to Social Security?

You can report through your my Social Security account online, by calling 1-800-772-1213, or at your local Social Security office. You must report within 10 days of a change. If you receive SSI, you may also need to report changes in living situation and resources.

What is a PASS, and how do I set one up?

A Plan to Achieve Self-Support (PASS) lets SSI recipients set aside income and resources for a work goal without those funds counting against SSI limits. You work with a Social Security work incentives planner to write the plan. Contact your local Social Security office or call 1-800-772-1213 to ask about work incentives planning services in your area.
