Can You Get SSDI and SSI at the Same Time? A Clear Guide to “Concurrent” Benefits

If you’re living with a disability and limited income, you may have heard of both SSDI (Social Security Disability Insurance) and SSI (Supplemental Security Income). It’s natural to ask:

Can you get SSDI and SSI at the same time?

In many cases, yes — you can receive both SSDI and SSI at the same time. This is called concurrent benefits. But it only happens when you meet both programs’ rules, and your SSDI payment is low enough that SSI can “fill in the gap.”

This guide walks through how that works, who qualifies, how the amounts are calculated, and what to watch for so you can better understand your options.

SSDI vs. SSI: The Basics

Before looking at getting both, it helps to understand how each program works.

What is SSDI?

SSDI (Social Security Disability Insurance) is a disability benefit based on your work history.

Key features:

You qualify by having:
- A severe, long-term disability that meets Social Security’s rules, and
- Enough work credits from paying Social Security (FICA) taxes.
Your benefit amount is based on your past earnings, not on your current income/resources (with some exceptions).
There is usually a five-month waiting period after your disability onset date before SSDI payments can start.
After receiving SSDI for 24 months, you generally qualify for Medicare.

What is SSI?

SSI (Supplemental Security Income) is a needs-based program for people with limited income and resources.

Key features:

You may qualify if you:
- Have a disability (or are blind or age 65+), and
- Have very limited income and resources under strict limits.
SSI is not based on work history. You can qualify even if you have never worked or have short work history.
The federal government sets a maximum federal SSI payment (called the federal benefit rate), and your actual payment is reduced by:
- Countable income, and
- Certain living arrangements.
SSI usually makes you eligible for Medicaid in many states (rules can vary by state).

Can You Receive SSDI and SSI at the Same Time?

The short answer: Yes, if you qualify for both

You can receive both SSDI and SSI at the same time if:

You meet the medical disability rules used for both SSDI and SSI, and
You have enough work credits for SSDI, and
Your SSDI monthly benefit is low enough that you still qualify for some SSI based on SSI’s income and resource rules.

When you get both SSDI and SSI, your case is called a concurrent claim.

How “Concurrent Benefits” Actually Work

How the amounts are calculated

SSI is considered a “last resort” program. That means it looks at:

What you already receive from SSDI and
Any other countable income

Then it may pay up to the difference between your income and the maximum SSI amount, if you still qualify.

Basic idea:

Start with the federal SSI maximum (a set amount that changes over time).
Subtract your countable income, including your SSDI benefit.
The result (if positive) is your SSI payment.

If your SSDI benefit alone is at or above the SSI maximum, you won’t get SSI. You’d only receive SSDI.

Simple example (numbers rounded for illustration)

Max federal SSI: assume $943/month (this figure changes over time; use it as an example only).
Your SSDI benefit: $600/month.
Countable income for SSI: $600 from SSDI (zoning out exceptions for simplicity).

Calculation:

$943 (max SSI) – $600 (SSDI) = $343 SSI payment

In that situation, you’d receive:

$600 SSDI
$343 SSI
Total monthly disability benefits: $943

If your SSDI benefit later increases (for example, due to cost-of-living adjustments), your SSI amount usually goes down. If it rises enough, your SSI can eventually stop altogether.

Quick Comparison: SSDI, SSI, and Concurrent Benefits

Feature	SSDI	SSI	Concurrent (Both)
Based on work history?	Yes – work credits required	No – needs-based	Yes and No – must meet both sets of rules
Disability standard	Same for SSDI & SSI	Same for SSDI & SSI	Same standard for both
Main qualifying factor	Insured through prior earnings	Low income and limited resources	Enough work credits + low enough income
Typical health coverage	Medicare (after waiting period)	Often Medicaid (rules vary by state)	Often Medicare + Medicaid (in many cases)
Can benefits change?	Yes – COLAs, work, reviews	Yes – any change in income/resources	Both SSDI and SSI rules apply

Who Usually Qualifies for Both SSDI and SSI?

You’re more likely to qualify for concurrent SSDI and SSI if:

Your SSDI benefit is relatively low, often seen when:
- You had low-wage jobs, or
- You didn’t work for very long before becoming disabled.
You have little or no other income.
Your resources (like bank accounts, property, certain assets) are within SSI limits.
You meet Social Security’s definition of disability (or are blind).

People who get higher SSDI benefits often do not qualify for SSI because their SSDI alone pushes them over SSI’s income limit.

How Your Resources and Income Affect SSI (Even When You Have SSDI)

SSDI and SSI treat income and assets differently, and this really matters when you’re trying to get both.

SSDI: Focused on your insured status and past earnings

For SSDI:

Assets/resources generally do not affect eligibility.
Your monthly benefit can be affected by:
- Certain types of work activity and
- Certain other disability benefits (like workers’ compensation in some situations).

SSI: Strict rules on income and resources

For SSI:

Income:
- Both earned income (wages, self-employment) and unearned income (like SSDI, pensions) can reduce SSI.
Resources:
- There is a strict resource limit (cash, bank accounts, some property).
- Certain items, such as your primary home and one primary vehicle, are often not counted, but many other assets are.

If your income or resources go over SSI limits, your SSI stops, even if you still qualify medically and still get SSDI.

Can You Start With One and Then Add the Other?

Starting with SSDI, then qualifying for SSI

You might:

Apply for SSDI based on your work history.
Find out your SSDI amount is lower than the SSI maximum.
Later apply for SSI (or have it evaluated automatically in some situations).

If your income and resources are low enough, you may be approved for SSI on top of SSDI.

Starting with SSI, then getting SSDI approved

Another common situation:

You first apply for SSI (especially if you have a weak or unclear work history).
Social Security later finds that you do have enough work credits and approves SSDI too.
At that point, your SSI may be recalculated:
- Your new SSDI benefit counts as income for SSI.
- Your SSI payment may decrease or end, depending on the amounts.

In this case, you could end up with concurrent benefits, at least for a time.

Do You Get Two Full Checks?

No. This is one of the most important points.

If you qualify for both:

You do not get two full, separate payments that stack on top of each other without limits.
Instead, SSDI is counted as income for SSI, and SSI is adjusted so that:
- Your total monthly amount is up to the SSI maximum (plus any state supplement, where applicable), not double or unlimited benefits.

Think of SSI as a “top-off” that helps bring you up to a certain basic income level if your SSDI alone is low.

Health Insurance When You Have SSDI and SSI

One reason some people pursue both SSDI and SSI is the potential health coverage combination.

SSDI and Medicare

After you’ve received SSDI for 24 months, you usually qualify for Medicare.
Medicare coverage typically includes:
- Hospital insurance (Part A),
- Medical insurance (Part B), and
- Optional prescription coverage (Part D), depending on enrollment choices.

SSI and Medicaid

In many states, being approved for SSI automatically qualifies you for Medicaid, often starting when SSI starts.
In some states, you must apply separately for Medicaid, even if you receive SSI, but SSI usually makes qualifying easier.

Having both: Medicare + Medicaid

If you receive both SSDI and SSI:

Over time, you may end up with Medicare (through SSDI) and Medicaid (through SSI).
Some people find that this combination:
- Reduces out-of-pocket costs, and
- Improves access to certain services, depending on state rules.

Coverage details and coordination between Medicare and Medicaid can be complex and vary by state. It’s often helpful to check with your state Medicaid office or a benefits counselor for specifics.

Work and Earnings: How They Affect SSDI, SSI, and Concurrent Benefits

If you receive disability benefits and want to work, you are allowed to work in many situations, but the rules differ for SSDI and SSI.

Work and SSDI

SSDI has rules about Substantial Gainful Activity (SGA) — if you earn over a certain monthly amount from work, Social Security may decide you are no longer disabled under their rules.
SSDI includes work incentives such as:
- Trial Work Periods
- Extended Period of Eligibility
  These allow you to test working while still receiving benefits under certain conditions.

Work and SSI

SSI also allows work, but reduces your payment as your earnings increase, according to specific formulas.
Some of your earnings are not counted, but as your earnings grow, your SSI payment typically goes down.
If your income gets too high, your SSI can stop, but you may still keep Medicaid coverage under certain rules in some states.

Working while getting both SSDI and SSI

If you have concurrent benefits and start working:

Your earnings may affect your SSI first, reducing or ending it.
If your earnings are very high, they may also affect your SSDI eligibility over time.
Your total benefit picture can shift, so it’s important to report all work and income changes promptly.

Common Situations Where People Receive Both SSDI and SSI

Here are some real-world patterns:

You worked part-time or at low wages for many years.
- You have enough work credits for SSDI, but your earnings were modest.
- Your SSDI benefit is low, and you meet the SSI income/resource limits.
- You receive a small SSDI payment plus SSI.
Your work history is short due to early disability.
- You worked some but became disabled at a relatively young age.
- Your SSDI benefit is limited, and you also qualify for SSI.
- The combination helps reach the SSI maximum level.
You first qualify for SSI, then SSDI is approved retroactively.
- Once SSDI begins, your SSI is recalculated.
- You might still receive both if your SSDI isn’t high, but your SSI amount goes down.

Key Takeaways: SSDI and SSI at the Same Time

Here is a quick summary you can scan:

✅ Yes, you can get SSDI and SSI at the same time. This is called concurrent benefits.
✅ You must qualify separately for both programs:
- SSDI: enough work credits + disability
- SSI: low income/resources + disability (or age 65+)
✅ SSI treats your SSDI payment as income, so it:
- Reduces your SSI amount, and
- May eliminate SSI if your SSDI is high enough.
✅ You do not get two full checks that stack without limits; SSI is designed to “top off” low SSDI.
✅ Many people with low SSDI benefits and very limited resources qualify for both.
✅ Having both may lead to Medicare (through SSDI) and Medicaid (through SSI) coverage, depending on timing and state rules.
✅ Changes in income, work, living arrangements, or resources can affect SSI quickly and may also affect SSDI under certain conditions.

What If You’re Not Sure Whether You Qualify?

If you’re unsure whether you could receive both SSDI and SSI:

Review your Social Security earnings record.
- This tells you whether you likely have enough work credits for SSDI.
Look closely at your income and resources.
- Compare them with general SSI limits to see if you may qualify for needs-based benefits.
Consider applying for both at the same time.
- Many people file a combined application, and Social Security evaluates eligibility for both SSDI and SSI.

Social Security representatives, legal aid organizations, and disability advocates often help people navigate these rules and paperwork. Many consumers find it useful to get personalized guidance, especially when income and resources are close to SSI’s limits or when work is involved.

Bottom line:
You can receive SSDI and SSI at the same time, but only if you meet both programs’ requirements and your SSDI benefit is low enough to still qualify for SSI. In that case, SSI acts as a supplement to SSDI, helping bring your total monthly income closer to SSI’s basic support level.
