You cannot receive the full benefit amount from both SSI and SSDI simultaneously, but you may receive a partial SSI payment alongside SSDI under specific circumstances.

Social Security has a rule called deeming that prevents you from collecting the maximum from both programs at once. If you are approved for SSDI (Social Security Disability Insurance), Social Security counts a portion of that SSDI payment as income when calculating your SSI (Supplemental Security Income) amount. The result is usually a reduced SSI payment, not two full payments.

The exception is narrow: you can receive both at their full amounts only if you were already receiving SSI before you became disabled and later may have access to for SSDI based on your own work record. This is rare and depends on the exact timing of when you filed and when Social Security processed your claims.

Key Takeaways

  • SSDI and SSI are counted together for payment purposes; receiving one reduces the other through a process called deeming.
  • If you receive SSDI, Social Security subtracts a portion of it from your SSI payment, usually leaving you with one primary benefit and little or no SSI.
  • You may receive both at full rates only in rare cases where you were already on SSI before your SSDI approval, and this depends on your work history and filing date.
  • The combined monthly payment you receive will not exceed what Social Security determines you are may have access to to based on your circumstances.

How Deeming Works When You Have Both SSDI and SSI

When Social Security calculates your SSI payment, it counts most of your SSDI as income. The exact amount subtracted depends on your living situation and whether you have dependents, but the principle is the same: your total benefit from both programs will not be higher than what Social Security says you should receive.

Here is the basic math: Social Security sets a maximum SSI payment amount each month (this varies by state and changes yearly). If you receive SSDI, Social Security subtracts that SSDI amount from the maximum, then gives you the difference as SSI. If your SSDI payment is already at or above the maximum SSI amount, you receive no SSI payment at all.

For example, if the maximum SSI payment in your state is $943 per month and you receive $800 in SSDI, Social Security would pay you $143 in SSI. If your SSDI is $1,000 per month, you would receive $0 in SSI because the SSDI alone exceeds the maximum.

When You Might Receive Both Programs at Full Rates

There is one scenario where you can receive the complete amount from both SSDI and SSI without deeming reducing your SSI: if you were already receiving SSI payments before you became disabled and later may have access to for SSDI based on your own work record.

This situation is uncommon because it requires a specific sequence of events. You would need to have been on SSI first (usually because of low income or a prior disability), then later gain enough work credits to may have access to for SSDI on your own record. When this happens, Social Security may continue your full SSI payment alongside your new SSDI payment, rather than reducing the SSI through deeming.

However, this outcome is not may provide and depends on how Social Security processes your claim and the exact dates involved. If you think this might apply to you, contact your local Social Security office to ask about your specific situation, because the rules around this exception are complex and case-by-case.

What Counts as Income for SSI When You Receive SSDI

Social Security counts your SSDI payment as unearned income when calculating your SSI. This means it is treated the same way as other income sources like pensions or interest from savings.

The first $65 of unearned income per month is not counted, and then Social Security counts half of the remaining amount. So if you receive $800 in SSDI, Social Security counts $65 as exempt, leaving $735. Half of that ($367.50) is counted as income against your SSI. The other half is disregarded. This is called the unearned income exclusion.

Other income you have — from work, family support, or other sources — is also counted and may further reduce your SSI payment. The more income you have from any source, the lower your SSI payment becomes.

How to Report Having Both SSDI and SSI

If you are already receiving SSI and then become approved for SSDI, Social Security will usually discover this automatically because both programs are in the same system. You do not need to file a separate report, but you should notify your local Social Security office in writing to confirm the change.

If you are receiving SSDI and want to apply for SSI, you will file an SSI application at your local Social Security office or online through Social Security's website. Bring proof of your current SSDI award, your lease or mortgage documents, and information about any other income or resources you have. Social Security will use your SSDI payment amount when calculating your SSI may be able to access and payment.

Keep Social Security informed of any changes to your income, living situation, or household members. Changes can affect both your SSDI and SSI payments, and reporting them promptly prevents overpayments that you would later have to repay.

Why You Might Receive Only SSDI or Only SSI Instead

Many people receive only SSDI and no SSI because their SSDI payment is high enough that it exceeds the SSI maximum. This is common for people who worked for many years and paid substantial Social Security taxes. Their SSDI benefit is based on their earnings record, not on financial need, so SSI does not apply.

Others receive only SSI because they do not have enough work credits to may have access to for SSDI. SSI is a needs-based program that does not require a work history; SSDI requires you to have worked and paid into Social Security. If you became disabled before working enough, or if you have not worked recently enough, you may only be able to receive SSI.

Some people are denied SSI because they have too many resources (savings, property, or other assets) even though they have low income. Resource limits for SSI are strict: $2,000 for an individual and $3,000 for a couple as of 2024, though these amounts can change. SSDI has no resource limit, so you can have substantial savings and still receive SSDI.

What Happens to Your Benefits If Circumstances Change

If your SSDI payment increases, your SSI payment will decrease by roughly the same amount (after the income exclusions are applied). If your SSDI payment decreases, your SSI may increase. Social Security recalculates your SSI each time your SSDI changes.

If you return to work and your SSDI ends, your SSI may increase because you will no longer have that SSDI income counted against you. However, your work income will then be counted, and it may reduce your SSI in a different way. Work incentives exist that allow you to keep some earnings without losing all your benefits, but the rules are complicated and vary depending on which program you are on.

If you move to a different state, your SSI payment amount may change because each state sets its own SSI supplement (the amount above the federal base). Your SSDI payment does not change based on where you live.

Frequently Asked Questions

If I get SSDI, can I also get SSI to make up the difference if my SSDI is low?

Yes, you can receive SSI alongside SSDI if your SSDI payment is below the maximum SSI amount for your state and you meet SSI's other requirements (low income and resources). However, the SSI payment will be reduced by most of your SSDI amount through deeming, so the total you receive from both programs combined will not be significantly higher than your SSDI alone.

What is the difference between SSDI and SSI income limits?

SSDI has no income limit — you can receive SSDI no matter how much money you earn or have. SSI has strict income and resource limits: your monthly income must be below a certain amount (varies by state), and you can have no more than $2,000 in resources. If you exceed these limits, you lose SSI, though SSDI continues.

Will I lose my SSI if I am approved for SSDI?

You will not lose SSI entirely, but your SSI payment will be reduced or eliminated depending on your SSDI amount. If your SSDI is high enough, you may receive $0 in SSI. If your SSDI is lower, you may receive a partial SSI payment. You remain enrolled in both programs, and your SSI can increase again if your SSDI decreases.

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

Yes. If you are approved for both programs, you may receive back pay (retroactive payments) from each one, though the amounts are calculated separately based on when each program determined you became disabled. The back pay from SSDI and SSI are not combined or offset against each other.

What should I do if Social Security says I owe money back because I received both SSDI and SSI?

Contact your local Social Security office immediately. Overpayments happen when Social Security miscalculates deeming or when you did not report a change in circumstances. You have the right to request a reconsideration of the overpayment, ask for a waiver if you were not at fault, or set up a repayment plan. Do not ignore an overpayment notice, as Social Security can offset future benefits or take other collection action.
