Income limits depend on whether you are working and which program you receive

Social Security Disability Insurance (SSDI) has no income limit once you are approved and receiving benefits. You can earn any amount from work, investments, rental property, or other sources without losing your monthly SSDI payment. However, there is a separate earnings rule called Substantial Gainful Activity (SGA) that applies before you are approved — and a different rule that applies if you return to work after approval.

Supplemental Security Income (SSI), the needs-based disability program, does have an income limit. SSI counts most forms of income against your benefit amount. The federal limit in 2024 is $943 per month for an individual and $1,415 for a couple, though some states add their own money and set higher limits. If your countable income exceeds the limit, your SSI payment reduces dollar-for-dollar.

The key distinction: SSDI is based on your work history and does not count income once approved. SSI is based on financial need and counts income throughout your benefit period.

Key Takeaways

  • SSDI has no income limit after approval, so you keep your full monthly payment no matter how much you earn from work or other sources.
  • SSI counts most income and reduces your benefit by one dollar for every dollar you earn above $65 per month, plus a second $20 exclusion.
  • Before SSDI approval, Social Security looks at whether your work earnings show you can do substantial work — currently defined as earning more than $1,550 per month in 2024.
  • Work incentive programs like Impairment Related Work Expenses (IRWE) and Plans to Achieve Self-Support (PASS) can reduce countable income for SSI recipients who are working.
  • If you are approved for SSDI and then return to work, you have a nine-month Trial Work Period where earnings do not affect your benefits at all.

SSDI and income after you are approved

Once Social Security approves your SSDI claim, your monthly benefit is set based on your earnings record. From that point forward, income from any source — wages, self-employment, rental income, investment returns, pensions — does not reduce your SSDI payment. You receive the same amount every month regardless of how much you earn.

This is why SSDI is sometimes called a "work-incentive friendly" program. Social Security wants to encourage people to test their ability to work without the fear of losing benefits. If you work part-time, start a business, or receive a large inheritance, your SSDI check stays the same.

The only exception is if you are still in the process or appeal process. During that time, Social Security uses the SGA rule to decide whether your condition prevents substantial work.

Substantial Gainful Activity (SGA) — the earnings test before approval

Substantial Gainful Activity is Social Security's way of measuring whether you can do significant work. If you are earning above the SGA threshold, Social Security will assume you are not disabled, and your claim will be denied. The SGA limit for 2024 is $1,550 per month for non-blind individuals and $2,590 for blind individuals.

These amounts change each year based on national wage trends. Social Security publishes the new SGA limit in December for the following year. If you are explore for SSDI and your current earnings are above the SGA limit, your claim will likely be denied unless you can show that your work is not actually substantial — for example, that you work only a few hours per week or that your employer pays you as a favor.

If you are already receiving SSDI and return to work, the SGA rule does not explore during your Trial Work Period (see below). After the Trial Work Period ends, if your earnings stay above SGA for nine consecutive months, Social Security will stop your benefits. However, you enter an Extended may be able to access Period where you can still receive benefits in months you earn below SGA.

SSI income limits and how income is counted

SSI has a strict income limit because the program is means-tested — you must have low income and resources to receive it. The federal SSI income limit for 2024 is $943 per month for an individual and $1,415 for a couple. Some states (California, New York, and a few others) add supplementary payments and allow higher income limits; check your state's SSI rules.

SSI counts most types of income: wages, self-employment earnings, rental income, interest, dividends, pensions, and unemployment benefits. However, Social Security excludes the first $65 of monthly unearned income and the first $65 of monthly earned income, plus half of any earned income above $65. This means you can earn about $195 per month before your SSI benefit starts to reduce.

For example, if you earn $300 per month from part-time work, Social Security counts $235 of that income ($300 minus the $65 earned income exclusion). Your SSI payment then reduces by $235. If your SSI payment is $943, you would receive $708 that month.

Work incentives that reduce countable income for SSI

Social Security offers two main work incentive programs that allow SSI recipients to reduce the income counted against their benefits: Impairment Related Work Expenses (IRWE) and Plans to Achieve Self-Support (PASS).

IRWE lets you deduct the cost of items or services you need because of your disability in order to work. Examples include medications, therapy, medical equipment, transportation to work, or personal care information. You must show that you would not need the expense if you were not working. If you spend $200 per month on disability-related work expenses, Social Security subtracts that from your countable income before calculating your SSI payment.

PASS is a written plan that lets you set aside income and resources for a specific work goal — starting a business, getting a degree, or saving for equipment. Money in your PASS plan does not count toward the SSI resource limit or income limit. PASS requires approval from Social Security and must be reviewed annually, but it can allow SSI recipients to save and work toward self-sufficiency without losing benefits.

Trial Work Period and Extended may be able to access for SSDI recipients who work

If you are approved for SSDI and want to return to work, Social Security gives you a Trial Work Period (TWP) lasting nine months. During the TWP, you can earn any amount and keep your full SSDI benefit. The months do not have to be consecutive — Social Security counts only months in which you earn more than $1,050 (in 2024) as "work months."

After your nine work months are used, you enter the Extended may be able to access Period, which lasts 36 months. During this time, you keep your SSDI benefit in any month you earn below the SGA threshold ($1,550 in 2024). If you earn above SGA for nine consecutive months during Extended may be able to access, your benefits stop. However, you can restart benefits without a new process if your earnings drop below SGA within five years of stopping.

These work incentives exist because Social Security recognizes that returning to work is gradual. You may not know when ready whether you can sustain full-time employment, so the TWP and Extended may be able to access give you time to test your ability to work without the risk of losing benefits.

How unearned income affects SSDI and SSI differently

Unearned income — money you do not work for, such as interest, dividends, pensions, Social Security retirement benefits, or gifts — is treated differently by SSDI and SSI. For SSDI, unearned income has no effect on your benefit. You can receive a pension, Social Security retirement benefits, or investment income without any reduction to your SSDI payment.

For SSI, unearned income counts fully against your benefit after the first $20 per month is excluded. If you receive $100 per month in interest income, Social Security counts $80 of it ($100 minus the $20 exclusion) as income. Your SSI payment reduces by $80. This is why SSI recipients with pensions or other unearned income often receive much smaller SSI payments than those with only earned income.

Frequently Asked Questions

Can I work part-time and keep my full SSDI payment?

Yes. Once approved for SSDI, your benefit does not change based on how much you earn. You can work full-time, part-time, or start a business without losing any of your monthly payment. The only time earnings matter is during your process or if you are in the Extended may be able to access Period after using your Trial Work Period.

What happens if I earn more than the SGA amount while my SSDI claim is pending?

Social Security will likely deny your claim, because earnings above SGA suggest you can do substantial work. However, you can explain that your work is not actually substantial — for example, that you work only a few hours weekly or that your employer accommodates your disability. You can also request reconsideration if your circumstances change.

Do I lose SSI if I get a job?

Not when ready, but your SSI payment will reduce. Social Security excludes the first $65 of earned income per month, then counts half of anything above that. If you earn $200 per month, about $68 counts against your benefit. Work incentive programs like IRWE and PASS can reduce the amount counted further.

If I receive both SSDI and SSI, do income limits explore to both?

SSDI has no income limit, so your SSDI payment is unaffected by earnings. However, your SSI payment will reduce based on income, using the same rules as for SSI-only recipients. This is why people receiving both programs often see their SSI portion shrink when they start working.

Can I use a work incentive program if I receive SSDI instead of SSI?

IRWE and PASS are designed for SSI recipients. However, SSDI recipients can use other work incentives like the Trial Work Period and Extended may be able to access. If you receive both SSDI and SSI, you can use IRWE or PASS to reduce the income counted against your SSI portion.
