How Social Security measures your income in 2025
Social Security counts income differently depending on which disability program you're on. If you receive SSDI (Social Security Disability Insurance), the income limit is tied to something called Substantial Gainful Activity, or SGA. In 2025, if you earn more than $1,550 per month from work, Social Security assumes you can work and may stop your benefits. If you're blind, the limit is higher: $2,590 per month.
These numbers change every year because Social Security adjusts them based on national wage trends. The 2025 amounts are higher than 2024 because average wages went up. If you're close to these limits or earn variable income, the exact month you cross the threshold matters—Social Security doesn't count every dollar the same way.
SSI (Supplemental Security Income) works on a completely different income limit. SSI is a needs-based program, so it counts almost all income you receive and reduces your monthly payment dollar-for-dollar above a small exclusion. The first $65 of monthly income is not counted, plus half of anything you earn above that. If you have unearned income (like a pension or child support), only the first $20 is excluded.
Key Takeaways
- SSDI's 2025 SGA limit is $1,550 per month for non-blind workers and $2,590 for blind workers; exceeding it can trigger a work incentive review or benefit suspension.
- SSI counts nearly all income and reduces your payment by $1 for every $2 you earn above $65 monthly, making even small earnings affect your check.
- Social Security counts only income you actually receive in a month, not income you're owed but haven't gotten yet.
- Self-employment income is calculated differently than wages and includes a deduction for business expenses before Social Security counts it against your limit.
What counts as income for SSDI
For SSDI, Social Security focuses on whether you're working and earning above the SGA threshold. Wages from a job count. Self-employment income counts. But many other things do not: your spouse's income, child support you receive, tax refunds, loans, gifts, and most government benefits (like food stamps or housing vouchers) are ignored.
If you work for yourself, Social Security subtracts your business expenses before counting what you earned. If you run a business and gross $2,000 but spend $600 on supplies and rent, Social Security counts $1,400 as your income. You'll need to document these expenses—receipts, invoices, and a record of what you paid for.
The timing of when you receive money matters. If you're paid on the 15th and the 30th of each month, Social Security counts only the income that actually landed in your account during that calendar month. If your employer owes you a paycheck but hasn't sent it yet, it doesn't count until you receive it.
What counts as income for SSI
SSI is stricter about income because it's a poverty program. Social Security counts wages, self-employment, pensions, annuities, rental income, and interest. It also counts in-kind income—if someone gives you food or pays your rent directly, SSI counts that as income at its cash value.
The exclusions are small. The first $65 of any monthly income is excluded. After that, you keep half of what you earn and lose half to the SSI reduction. If you earn $200 in a month, Social Security excludes the first $65, counts $135, and reduces your SSI payment by $67.50. If you have unearned income like a pension, only the first $20 is excluded, and the rest reduces your payment dollar-for-dollar.
In-kind support and maintenance—food or shelter someone provides without charging you—is counted as income. If your adult child lets you live in their house rent-free, SSI may count that as income. The exact value depends on whether you pay for any of your own food. This is one of the most complicated parts of SSI, and the rules change based on your living situation.
How self-employment income is calculated
If you work for yourself, Social Security needs to see your business records. For SSDI, you report your net self-employment income (what you make after expenses) against the SGA limit. For SSI, the same calculation applies, but the threshold is much lower because SSI counts nearly all income.
Keep records of everything: invoices showing what you charged, receipts for supplies, rent for workspace, equipment costs, and any wages you paid to employees. Social Security will ask for tax returns, profit-and-loss statements, or bank records showing deposits and withdrawals. If you can't document your expenses, Social Security may count your gross income instead, which could push you over the limit.
Some people with disabilities run small businesses or do gig work. If you drive for a rideshare service, deliver groceries, or freelance, each dollar you earn counts toward the SGA limit (for SSDI) or reduces your SSI payment. Mileage, equipment, and platform fees are business expenses you can deduct, but you need receipts.
Income limits if you're working and receiving benefits
SSDI has a built-in work incentive called the Trial Work Period. For nine months (not necessarily consecutive), you can earn any amount and keep your full SSDI benefit. This is designed to let you test whether you can work without when ready losing your safety net. After the Trial Work Period ends, the SGA limit kicks in.
Once you exceed SGA for a month, Social Security doesn't stop your benefits when ready. You enter an Extended may be able to access Period where you keep your benefits for up to 36 months while you work, even if you earn above SGA. After that period, benefits stop if you're still earning above the limit. This gives you time to see if work is sustainable for you.
SSI has no Trial Work Period. Any income above the small exclusion reduces your payment right away. But SSI also has a Plan to Achieve Self-Support (PASS), which lets you set aside income and resources for a specific work goal without it counting against your SSI. A PASS is complex and requires a written plan, but it can protect your benefits while you save for education, equipment, or a business.
Income that does not count against your limits
Social Security ignores certain income entirely. For both SSDI and SSI: gifts, loans, tax refunds, rebates, and money you inherit do not count. Proceeds from selling your home or car do not count. Workers' compensation and certain other government benefits have their own rules, but many do not reduce your Social Security benefits.
For SSDI specifically, your spouse's income, your children's income, and support from family members do not count. If your adult child gives you $500 a month to help with rent, SSDI ignores it. SSI is different—if someone else pays your rent or buys your food, SSI counts it as income to you.
Impairment Related Work Expenses (IRWE) are costs you pay because of your disability to work—a wheelchair ramp, medication, transportation, or a personal assistant. For SSDI, these expenses are subtracted from your earnings before Social Security counts them against SGA. If you earn $1,800 but spend $300 on disability-related work costs, Social Security counts $1,500.
When income limits change and how to stay informed
The SGA limit increases every January because it's tied to the national average wage index. Social Security announces the new limit in October or November of the previous year. The 2025 limit of $1,550 (or $2,590 for blind workers) will change again in January 2026. If you're close to the limit, check the Social Security website in the fall to see what next year's number will be.
SSI's income exclusions ($65 for earned income, $20 for unearned) also change annually, though they change less often than SGA. Social Security publishes updated figures on its website and in the Red Book, a free guide to work incentives and income limits.
Your local Social Security office can tell you the current limits and how your specific income will be counted. You can also call 1-800-772-1213 or visit ssa.gov. If your income is variable—some months high, some months low—ask Social Security how they'll count it. Knowing the rules before you start working or increase your hours can prevent an unexpected benefit reduction.
Frequently Asked Questions
Does my spouse's income count against my SSDI limit?
No. SSDI only counts your own income. Your spouse's earnings, pension, or other income does not affect your SSDI benefit. SSI is different—if you're married and both on SSI, your spouse's income counts toward your household limit.
What if I earn money one month but not the next?
Social Security counts only the income you actually receive in each calendar month. If you earn $2,000 in January and $500 in February, January counts against SGA but February does not. This matters for self-employed people and gig workers whose income varies.
Do I have to report my income to Social Security?
Yes. If you're working and receiving SSDI or SSI, you must report your earnings. SSDI beneficiaries report through the Ticket to Work program or directly to their local office. SSI beneficiaries report to their SSI case manager. Failing to report can result in an overpayment you'll have to repay.
Can I deduct taxes from my income before Social Security counts it?
No. Social Security counts your gross income before taxes. If you earn $1,600 and pay $150 in taxes, Social Security counts $1,600 against the SGA limit. Taxes are your responsibility, not Social Security's.
What happens if I go over the income limit for one month?
For SSDI, one month over SGA does not when ready stop your benefits. You enter a review process. For SSI, your payment is reduced based on how much you earned. If you're on SSDI and expect to go over the limit, contact your local office before it happens so you understand what comes next.
