Income limits depend on which program you're on, and the rules are different for SSDI and SSI
Social Security Disability Insurance (SSDI) has no income limit. You can earn money and still receive your full benefit amount. The program does not care how much you make from work, investments, pensions, or other sources. What matters is whether you can work at a substantial gainful activity level — currently defined as earning more than $1,550 per month (or $2,590 if you are blind). If you earn above that threshold, Social Security may decide you are no longer disabled and can stop your benefits.
Supplemental Security Income (SSI) works the opposite way. It has strict income and resource limits. If your countable income exceeds $943 per month (as of 2024, though this amount changes yearly), your SSI payment reduces dollar-for-dollar. You also cannot own more than $2,000 in countable resources as a single person, or $3,000 as a couple. Countable resources include cash, bank accounts, stocks, and property — but not your home or one vehicle.
The difference matters because SSDI is based on your work history, while SSI is a needs-based program for people with low income and few assets. Many people receive both programs at once, which means both sets of rules explore to them.
Key Takeaways
- SSDI has no income limit, but earning more than $1,550 per month can trigger a medical review that may end your benefits if Social Security decides you can work.
- SSI reduces your monthly payment by $1 for every $1 of countable income above $943 per month, making it impossible to receive SSI if you earn a regular wage.
- Work incentives like the Plan to Achieve Self-Support (PASS) and Impairment Related Work Expenses (IRWE) can shield some of your earnings from counting against your benefits.
- If you receive both SSDI and SSI, the SSDI rules explore first, then the SSI rules explore to what remains.
- Unearned income — from pensions, investments, or family support — counts the same way as earned income under SSI rules.
What counts as income under SSDI
Under SSDI, Social Security only cares whether you are working at a substantial gainful activity level. The $1,550 monthly threshold (or $2,590 if blind) is the key number. If you earn less than that, you keep your full benefit. If you earn more, Social Security will review your case to determine whether your disability still prevents you from working.
This review is not automatic disqualification. Social Security looks at whether the work you are doing is actually substantial and gainful — meaning it is real, productive work for which you are paid. Self-employment, work-study, sheltered workshops, and unpaid volunteer work have different rules. But if you are earning a regular wage above the threshold, expect a medical review within a few months.
Unearned income — Social Security checks, pensions, rental income, investment returns, gifts — does not count toward the substantial gainful activity test under SSDI. You can receive a large inheritance or pension and keep your SSDI benefits. The program only cares about work.
What counts as income under SSI
SSI counts both earned and unearned income, and the rules are strict. Earned income is money you make from work. Unearned income includes Social Security benefits, pensions, unemployment, child support, gifts, and rental income. Both reduce your SSI payment.
The first $65 of earned income per month is excluded, and then half of the remainder is excluded. So if you earn $200 per month, Social Security excludes the first $65, counts half of the remaining $135 ($67.50), and reduces your SSI by $67.50. Unearned income has no exclusion — it reduces your SSI dollar-for-dollar after the first $20 per month.
Because of these rules, most people on SSI cannot work at a regular job. Even part-time work quickly reduces the benefit to zero. This is why work incentives exist — they create exceptions to these counting rules so you can test your ability to work without losing your entire benefit when ready.
Work incentives that protect your earnings
The Plan to Achieve Self-Support (PASS) is the most powerful tool for SSI recipients who want to work. A PASS is a written plan you create with a work incentive specialist. It sets aside income and resources for a specific work goal — like training for a new job, buying equipment, or starting a business. Money set aside under a PASS does not count as income or resources for SSI purposes. You can work and save thousands of dollars without losing your benefit, as long as the money goes toward your stated goal.
For SSDI recipients, Impairment Related Work Expenses (IRWE) allow you to deduct certain costs from your earnings before the substantial gainful activity test is applied. If you need a personal assistant, special transportation, medical equipment, or therapy to work, those costs can reduce your countable earnings. If your gross earnings are $2,000 but your IRWE is $500, Social Security counts only $1,500 toward the substantial gainful activity threshold.
Both SSDI and SSI recipients can use the Student Earned Income Exclusion if you are under 22 and a student. Up to $2,170 per month in earned income (as of 2024) is excluded from both programs, up to a yearly maximum.
What happens if you earn too much
Under SSDI, if you earn above the substantial gainful activity level, Social Security will send you a notice that your case is under review. You will have the chance to explain your work and provide medical evidence. If Social Security concludes you can work, your benefits will stop. You do not lose benefits when ready — there is usually a grace period of a few months while the review happens.
If your benefits stop and you later become unable to work again, you can request reinstatement. SSDI has a special rule called expedited reinstatement that allows you to restart benefits within five years if your condition worsens, without having to file a new process and wait months for a decision.
Under SSI, if your income exceeds the limit, your payment straightforward reduces or stops. There is no review period — the math is automatic. If you earn $1,500 per month and your SSI payment is $943, your new payment becomes $0 because your income exceeds the limit. If your income later drops, your SSI payment restarts the following month.
How resources affect SSI but not SSDI
SSI has a resource limit of $2,000 for a single person. Resources are things you own that can be converted to cash — bank accounts, stocks, bonds, vehicles beyond one, real estate beyond your home. If you inherit money or receive a lump-sum settlement, it counts as a resource. Once you exceed $2,000, you lose SSI entirely until your resources drop back below the limit.
SSDI has no resource limit. You can own a house, multiple vehicles, investment accounts, and savings without affecting your benefit. The only thing that matters is work.
Some resources are excluded from the SSI limit: your primary home, one vehicle, household goods, personal effects, and certain work-related items. If you receive a settlement from a lawsuit and want to protect it, you can ask Social Security which resources are excluded and plan accordingly. Some states also allow you to set aside money in a Special Needs Trust that does not count as a resource.
How to report income changes to Social Security
You are required to report changes in income to Social Security within 10 days. For SSDI, this means reporting if you start working or if your earnings cross the substantial gainful activity threshold. For SSI, you must report any change in earned or unearned income.
You can report by phone, mail, or online through your Social Security account at ssa.gov. If you are working with a work incentive specialist or a representative, they can help you report. Failing to report can result in an overpayment — money Social Security paid you that you were not may have access to to — and you will have to repay it.
Many people worry that reporting work will cause them to lose benefits when ready. That is not how it works. Reporting is how Social Security knows to explore the rules correctly. If you do not report, you risk an overpayment and possible fraud charges. If you do report and your earnings are protected by a work incentive, your benefit continues.
Frequently Asked Questions
Can I work part-time and keep my SSDI?
Yes, as long as you earn less than $1,550 per month. You keep your full benefit. If you earn more, Social Security will review your case to see if you can still work. Work incentives like IRWE can reduce your countable earnings if you have disability-related work expenses.
What if I get a gift or inheritance while on SSI?
A gift or inheritance counts as a resource under SSI. If it pushes your total resources above $2,000, you lose SSI until the amount drops below the limit. The first $20 per month of unearned income is excluded, but a lump sum is treated as a resource, not monthly income. Talk to a work incentive specialist about protecting the money through a Special Needs Trust.
Does my spouse's income affect my disability benefits?
Under SSDI, no — your spouse's income does not affect your benefit at all. Under SSI, your spouse's income counts toward your household limit. If you are married and both on SSI, the rules are more complex. Contact Social Security directly to understand how your specific situation works.
What is the difference between a work incentive and a benefit?
A work incentive is a rule that lets you keep more of your earnings without losing your benefit. It does not give you extra money — it protects the money you earn from counting against your benefit. PASS and IRWE are the main ones. You have to set them up in advance, usually with help from a work incentive specialist.
If I stop working, can I get my benefits back?
Under SSDI, if your benefits stopped because you were working, you can request expedited reinstatement within five years if your condition worsens. Under SSI, if your income drops below the limit, your payment restarts the following month automatically. No new process is needed.
