The federal government sets a base SSI payment, then reduces it based on your income and resources

The Supplemental Security Income (SSI) payment amount starts with a federal base rate set each year by Social Security. For 2024, that base is $943 per month for an individual (the amount changes annually for inflation). From that number, Social Security subtracts any income you receive and counts your savings and assets against a resource limit. The result is your monthly SSI check.

The calculation is straightforward in structure but depends entirely on what you earn and own. If you have no other income and own nothing beyond the allowed limits, you receive the full federal rate. If you work, receive other benefits, or have savings, your SSI payment shrinks dollar-for-dollar or by a percentage, depending on the type of income.

Some states add money on top of the federal payment. These state supplements vary widely — some states pay nothing extra, while others add $50 to $100 or more per month. Your total SSI check is the federal amount minus reductions, plus any state supplement your state provides.

Key Takeaways

  • The federal SSI base payment changes each January for inflation, and your state may add a supplement on top of it.
  • Social Security subtracts most of your earned income (wages from work) and all of your unearned income (pensions, unemployment, other benefits) from your SSI payment.
  • You can own up to $2,000 in countable resources as an individual; anything above that reduces or stops your SSI payment.
  • Work incentives allow you to exclude the first $65 per month of earnings plus half of the rest, so working does not automatically eliminate your SSI.
  • Your state's SSI supplement amount depends on where you live and whether you live in your own home or an institution.

How income reduces your SSI payment

Social Security divides income into two categories: earned income (money you make from working) and unearned income (everything else — pensions, Social Security benefits, unemployment, child support, gifts over $20 per month). Each type is counted differently.

For unearned income, Social Security subtracts it dollar-for-dollar from your SSI payment. If you receive a $200 monthly pension and the federal SSI base is $943, your SSI payment becomes $743. There is no exclusion or buffer — the full amount counts against you.

Earned income has a work incentive built in. Social Security excludes the first $65 per month you earn, then counts only half of what you earn above that. If you work and earn $200 per month, Social Security counts $65 as excluded income (you keep it), then counts half of the remaining $135 — that is $67.50 — against your SSI. Your payment would be reduced by $67.50, not $200. This rule exists to encourage work without immediately cutting off your entire benefit.

Gifts and in-kind support (someone paying your rent or food directly) are treated as unearned income, though the rules are complex. A gift of money under $20 per month does not count. If someone pays your rent, Social Security counts that as in-kind support and reduces your payment by one-third of the federal rate (roughly $314 in 2024), regardless of the actual rent amount.

Resource limits and what counts as an asset

SSI has a strict resource limit: you can own $2,000 in countable resources as an individual, or $3,000 if you are married and both spouses receive SSI. Anything above those limits disqualifies you from SSI entirely — you receive no payment until your resources drop back below the limit.

Not everything you own counts. Your primary home does not count, no matter its value. One vehicle does not count if it is used for transportation. Household goods and personal effects do not count. Life insurance with a face value under $1,500 does not count. Burial plots and burial funds up to $1,500 per person do not count.

What does count: cash in hand, money in bank accounts, stocks, bonds, investment accounts, a second vehicle, a second home, and life insurance over $1,500. If you inherit money or receive a lump-sum payment (a lawsuit settlement, back pay, a bonus), that money counts immediately toward your resource limit. Many people who receive a one-time payment lose SSI until they spend it down below $2,000.

Some resources are excluded for a limited time. If you receive a work incentive payment or a plan-to-achieve-self-support (PASS) payment, Social Security may exclude it for a set period. If you receive an income tax refund, you have nine months to spend it before it counts as a resource. These exclusions exist to help people work toward independence without losing benefits immediately.

State supplements and how they change your payment

Twenty-seven states and Washington, D.C. provide SSI state supplements — extra money added to the federal payment. The amount varies by state and sometimes by living situation. Some states pay the same supplement whether you live alone, with family, or in a group home. Others pay different amounts depending on where you live.

A few states pay substantial supplements. California, for example, adds roughly $70 per month for an individual living independently. New York adds roughly $100 per month. Many states add $10 to $30. Some states add nothing at all. If you move to a different state, your SSI payment will change because the supplement changes — this is one reason people on SSI need to notify Social Security before relocating.

State supplements are funded by state budgets, not federal funds, and they can change year to year. Some states have reduced their supplements during budget shortfalls. If you receive a state supplement, Social Security will tell you the amount in your award letter, and it will appear as a separate line item on your payment stub.

How living situation affects your payment

Where you live can change your SSI amount through the in-kind support rule. If someone else pays for your food or housing, Social Security counts that as in-kind support and reduces your payment. The reduction is one-third of the federal base rate, applied once per month regardless of how many people are paying for your support.

If you live in your own home and pay your own rent or mortgage, you receive the full payment (minus income and state variations). If you live with family and they pay your rent, your payment is reduced by one-third of the federal rate. If you live in a group home or institution where the facility pays for your food and shelter, the reduction still applies, though some states have different rules for institutional settings.

This rule creates a common trap: if an adult child lets a parent on SSI live with them rent-free, Social Security counts that as in-kind support and cuts the parent's payment. The reduction is automatic — Social Security does not ask whether the arrangement was intentional. To avoid it, the parent should pay rent to the adult child, even a small amount. Paying $100 per month in rent eliminates the in-kind support reduction, even if the actual cost of housing is higher.

Work incentives that protect your SSI while you earn

Social Security has several programs designed to let you work without immediately losing SSI. The most common is the Plan to Achieve Self-Support (PASS), which 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.

Under PASS, you write a plan describing your goal, how much money you need, and how long it will take. Social Security excludes the money you set aside from your resource count and excludes the income you earn toward that goal from your income count. If your goal is to become a bookkeeper and you need $3,000 for training, you can set aside $3,000 and earn money specifically for that training without losing SSI, even though you would normally lose SSI at $2,000 in resources.

Another option is Impairment Related Work Expenses (IRWE), which excludes certain costs you incur because of your disability. If you need a personal assistant to help you work, or specialized equipment, or transportation beyond what a non-disabled person would need, those costs can be deducted from your earned income before Social Security counts it against your SSI. This reduces the amount of earnings that reduce your payment.

A third option is Student Earned Income Exclusion (SEIE), which excludes earned income for students under age 22. If you are a full-time student and work part-time, Social Security excludes up to $8,230 per month of your earnings (the limit changes annually). This allows students to work and save without losing SSI.

How to find out your specific payment amount

Your SSI payment amount is listed in your award letter, which Social Security sends when your claim is approved. The letter shows the federal base rate, any state supplement, and the total monthly payment. If your circumstances change — you start working, receive other income, move to a different state, or your living situation changes — Social Security will recalculate your payment and send you a new notice.

You can contact Social Security directly to ask how a specific change would affect your payment. Call 1-800-772-1213 or visit your local Social Security office. Social Security representatives can walk through a hypothetical scenario — "If I earn $300 per month, what would my SSI be?" — and give you an estimate. This is useful before you start working or make a major change, so you understand what to expect.

Your payment stub, which arrives with your check or direct deposit, shows the current month's payment and any deductions. If the amount changes unexpectedly, the stub usually includes a notice explaining why. If you do not understand the change, call Social Security and ask for an explanation — payment errors do happen, and Social Security can correct them.

Frequently Asked Questions

Does the federal SSI payment amount change every year?

Yes. Social Security adjusts the federal base SSI payment each January based on the cost-of-living adjustment (COLA). The exact percentage varies year to year. State supplements may or may not increase with COLA, depending on state law. Social Security will notify you in writing if your payment amount changes.

If I inherit money, do I lose SSI immediately?

Yes, inherited money counts as a resource immediately. If the inheritance pushes you above $2,000 in resources, you lose SSI until you spend the money back down below the limit. Some people use a PASS plan to set aside inherited funds for a work goal, which can protect part of the inheritance from counting against SSI.

Can I work part-time and still receive SSI?

Yes. The work incentive rules allow you to earn money and keep most of your SSI payment. The first $65 per month of earnings is excluded, then half of earnings above that count against SSI. You can earn several hundred dollars per month and still receive a partial SSI payment, depending on your other income and resources.

What happens to my SSI if I move to a different state?

Your federal SSI payment stays the same, but your state supplement changes based on where you move. Some states pay more than others. You must notify Social Security before you move so they can recalculate your payment with the new state's supplement included. Moving without notifying Social Security can result in overpayment that you will owe back.

Does my spouse's income count against my SSI?

If you are married and both receive SSI, each person's income is counted separately against their own payment. If only one spouse receives SSI, the other spouse's income does not count against the SSI recipient's payment. However, the couple's combined resources are counted together against the $3,000 limit for married couples receiving SSI.
