Two federal programs send disability checks, and which one you receive depends on your work history

Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI) are the two programs that send monthly disability checks. SSDI is based on your own work record and the taxes you paid into Social Security. SSI is a needs-based program for people with low income and few assets, regardless of work history. Most people receive one or the other, not both, though in rare cases you can receive a small amount of both.

The Social Security Administration (SSA) processes and sends both types of checks. They do not come from a separate disability office or a different agency. The same organization that handles retirement benefits handles disability benefits. Your check arrives either by direct deposit to your bank account or on a prepaid debit card called a Direct Express card.

The amount you receive each month is set by a formula that depends on which program you are on. SSDI amounts are based on your lifetime earnings record. SSI amounts are based on a federal base rate that changes each year, reduced by any other income you have. Neither program sends the same amount to everyone.

Key Takeaways

  • SSDI checks come from your own Social Security work record; SSI checks come from general federal funds for people with low income and assets.
  • The Social Security Administration sends both types of checks, either by direct deposit or prepaid debit card.
  • SSDI amounts depend on your earnings history; SSI amounts depend on a federal base rate minus any other income you receive.
  • Your check arrives on the same day each month, and you can see the payment schedule on your Social Security account online.
  • If you work while receiving benefits, your check amount may be reduced or stopped temporarily, depending on which program you are on and how much you earn.

How SSDI checks are funded and what determines your amount

SSDI comes from the Social Security Disability Insurance Trust Fund, which is funded by payroll taxes. When you worked, you and your employer each paid 6.2 percent of your wages into Social Security. That money goes into a single pool that pays retirement benefits, survivor benefits, and disability benefits. Your SSDI check is not a separate account in your name—it comes from the shared trust fund, but your may be able to access and amount are based on your individual work record.

The SSA calculates your SSDI amount using your Primary Insurance Amount (PIA), which is based on your 35 highest-earning years. The formula is set by federal law and does not change based on need or other income. If you have not worked 35 years, the SSA counts zero-earning years, which lowers your amount. If you worked more than 35 years, only your top 35 count.

Your SSDI check amount is the same whether you are 35 or 75 when you start receiving it. The formula does not adjust for age at approval. However, if you are also may be able to access for retirement benefits on your own record or on a family member's record, the SSA may pay you the higher of the two amounts, not both.

How SSI checks are funded and what determines your amount

SSI comes from the U.S. Treasury's general revenue, not from Social Security payroll taxes. It is a federal welfare program, not an insurance program. The federal government sets a base rate each year—in 2024, the federal base rate is $943 per month for an individual—but this amount changes annually. Some states add their own money on top of the federal amount, so your total SSI check may be higher if you live in a state that supplements SSI.

Your SSI amount is reduced dollar-for-dollar by other income you receive. If you have a job and earn $200 in a month, your SSI check is reduced by roughly $133 (because the first $65 of monthly earnings and half of the rest are not counted). If you receive SSDI, that counts as income and reduces your SSI. If you receive unemployment benefits, those reduce SSI too.

SSI also has strict asset limits. You can own no more than $2,000 in countable assets as an individual, or $3,000 as a couple. Your home and one vehicle do not count. Money in certain savings accounts set aside for work incentives does not count. If your assets exceed the limit, you lose SSI until your assets drop back down.

When your check arrives and how to receive it

The SSA sends checks on a schedule based on your birth date. If you were born on the 1st through the 10th of any month, your check arrives on the second Wednesday of each month. If you were born on the 11th through the 20th, your check arrives on the third Wednesday. If you were born on the 21st or later, your check arrives on the fourth Wednesday. This schedule applies to both SSDI and SSI.

You can see your exact payment date by logging into your Social Security account at ssa.gov. You can also call 1-800-772-1213 to confirm your payment date. The SSA does not send checks on weekends or federal holidays, so if your scheduled date falls on a holiday, your check arrives the day before.

Direct deposit is the fastest and safest way to receive your check. The money goes into your bank account on your payment date. If you do not have a bank account, you can receive your check on a Direct Express prepaid debit card. The card is issued by Comerica Bank and works like a regular debit card at ATMs and stores. If you lose the card or it is stolen, you can call the Direct Express customer service line to freeze it and request a replacement.

What happens to your check if you work or have other income

SSDI has an earnings test that applies for the first 9 months you receive benefits while working. If you earn more than $1,550 per month (in 2024), the SSA counts that as substantial work activity and may stop your benefits. After 9 months of substantial work, your benefits stop, but you enter a 36-month period where you can return to benefits without a new medical review if your earnings drop below the limit again. After the 36-month window closes, you would need to reapply.

SSI has a different rule. Your SSI check is reduced by your earnings, but you are allowed to work. The first $65 of monthly earnings do not count, and half of earnings above $65 do not count. So if you earn $200, only about $67.50 counts as income, and your SSI is reduced by that amount. You can continue receiving SSI while working as long as your countable income stays below the SSI payment amount.

If you receive other income—such as unemployment, workers' compensation, pension payments, or money from family members—that income may reduce or stop your benefits. SSDI is not affected by other income, but SSI is. Report any change in income to the SSA within 10 days to avoid overpayment.

How to set up or change how you receive your check

If you are already receiving benefits and want to switch from a check to direct deposit, or from one bank account to another, you can do this online through your Social Security account. Log in at ssa.gov, go to "Manage Your Benefits," and select "Change Direct Deposit Information." The change usually takes one or two payment cycles to go into effect.

If you do not have an online account, you can call 1-800-772-1213 to request a change. You will need to provide your new bank account number and routing number, or request a Direct Express card. If you are explore for benefits for the first time, the SSA will ask you how you want to receive your check during the process process.

If your bank account is closed or your Direct Express card is lost, contact the SSA when ready. If you do not update your payment information, your check may be returned to the SSA, and you will have to wait for a replacement check to be issued and mailed to you, which can take several weeks.

What to do if your check does not arrive on schedule

If your check does not arrive by the day after your scheduled payment date, log into your Social Security account and check your payment history. The account shows whether the payment was processed and sent. If the payment shows as sent but you have not received it, contact your bank to ask if the deposit is pending. Bank deposits sometimes take an extra day to appear in your account.

If the payment does not show in your account history, or if your bank says it never received the deposit, call the SSA at 1-800-772-1213. Have your Social Security number and bank account information ready. The SSA can trace the payment and issue a replacement check or reissue the direct deposit. If a check was lost in the mail, the SSA can stop payment on the original check and send a new one.

Do not wait more than a few days to report a missing payment. The longer you wait, the harder it is to trace the payment and issue a replacement. If you are on SSI and your check does not arrive, report it right away because SSI payments are smaller and missing even one month can affect your ability to pay rent or buy food.

Frequently Asked Questions

Can I receive both SSDI and SSI at the same time?

In most cases, no. If you are on SSDI, your SSDI payment counts as income and reduces your SSI to zero. However, in a few states, you may receive a small SSI supplement if your SSDI amount is very low. Contact your local SSA office to learn about your state has a supplemental program.

What if I move to a different state—does my check amount change?

SSDI does not change if you move. Your amount is based on your work record, not where you live. SSI may change if you move to a state that supplements SSI differently. Some states add money to the federal SSI rate; others do not. Contact the SSA before you move to learn about your SSI amount will change.

If I get married, does my check amount change?

SSDI does not change if you marry. Your amount is based on your work record alone. SSI may change because the asset and income limits are higher for couples. If you are on SSI and marry someone who also receives SSI, your combined countable income and assets are evaluated together, which may increase or decrease your total benefits.

Can I have my check sent to someone else if I cannot manage money?

Yes. You can request a representative payee—a person the SSA appoints to receive and manage your benefits on your behalf. The payee can be a family member, a social worker, or a nonprofit organization. The SSA requires the payee to use the money for your current maintenance and best interests. You can request a payee change by calling 1-800-772-1213.

What happens to my check if I am in jail or prison?

SSDI and SSI both stop if you are convicted of a crime and imprisoned for more than 30 days. Your benefits resume the month after you are released. You must report your incarceration to the SSA within 10 days to avoid overpayment. If you receive an overpayment, the SSA may ask you to repay it.
