SSI vs SSDI in Maryland: which program fits your situation

Last updated 2026-07-09

What is the core difference between SSI and SSDI?

SSDI is disability insurance you paid for. SSI is a need-based benefit that doesn't care whether you ever worked. Both come from the Social Security Administration, but the money comes from two different places and the programs serve two different groups.

SSDI stands for Social Security Disability Insurance. You pay into it every time Social Security taxes come out of your paycheck. Rack up enough work credits, become disabled, and you can draw on that coverage. Think of it as a disability policy you funded over your working years. ^[1]

SSI stands for Supplemental Security Income. It pays people who are disabled, blind, or aged 65+ and have very little income and almost no assets, no matter their work history. The money comes from general federal tax revenue, not the Social Security trust fund. ^[2]

For Maryland residents, the split usually works out like this. If you worked steadily and then became disabled, SSDI is almost certainly your primary program. If you have little or no work history, or your SSDI benefit would be tiny, SSI is your safety net. Some people qualify for both at once. That's called "concurrent benefits," and it happens more often than most applicants expect.

How do the eligibility rules differ for SSI vs SSDI in Maryland?

The medical test is identical for both programs. The money test is where they split apart. SSA uses the same five-step sequential evaluation and the same Blue Book of impairment listings to decide if you're disabled. ^[3] What differs is everything on the non-medical side.

SSDI eligibility requirements:

You need enough work credits. In 2025, you earn one credit for every $1,810 in covered earnings, up to four credits a year. Most people need 40 credits total, with 20 earned in the last 10 years before disability. Younger workers need fewer, because they've had fewer years to build them up. ^[4]

There is no income or asset limit for SSDI. A millionaire with the right work history can technically collect it. What matters is whether you're earning over the Substantial Gainful Activity threshold, which is $1,620/month in 2025 (or $2,700/month if you're blind). ^[4]

SSI eligibility requirements:

No work history required. But the financial limits are strict. In 2025, your countable income must fall below the federal benefit rate, and your countable resources cannot exceed $2,000 for an individual or $3,000 for a couple. ^[2] Those resource limits have not moved since 1989. That's not a typo. They are genuinely tight.

Some things don't count against the resource limit: your primary home, one car of any value if you use it for transportation, household goods, and burial funds up to certain amounts. ^[2]

For a closer look at the work credit side of SSDI, see SSDI Work Credits Explained: How Many Do You Need?.

The disability standard matters no matter which program you chase. SSA's definition requires a medically determinable impairment that "has lasted or can be expected to last for a continuous period of not less than 12 months" or is expected to result in death, and that prevents you from doing any substantial gainful activity. ^[5] See What Counts as a Disability? The SSA's Definition Explained.

How much does each program pay in Maryland in 2025?

The two programs pay very different amounts, and Maryland's state supplement adds one more small layer on top of SSI. The federal SSI maximum in 2025 is $967/month for an individual. The average SSDI check for a disabled worker is about $1,580/month.

SSDI payments run off your Average Indexed Monthly Earnings, a formula SSA uses to size up what you earned across your working life. The average benefit for a disabled worker in early 2025 is roughly $1,580/month, per SSA's published data. ^[1] High earners get more. The maximum possible SSDI benefit in 2025 is $4,018/month, though almost nobody hits that ceiling.

SSI federal payments in 2025 top out at $967/month for an eligible individual and $1,450/month for an eligible couple. ^[2] Those are the federal benefit rates after the 2025 cost-of-living adjustment.

Maryland's state supplement rides on top of the federal SSI payment for residents who live independently. As of 2025, it's modest, roughly $10 to $23/month depending on your living arrangement. The exact figures shift over time, and the Maryland Department of Human Services administers the payment alongside SSA. ^[6] It won't reshape your budget. It does mean Maryland SSI recipients land slightly above the federal floor.

If you qualify for both SSDI and SSI at once, your SSI shrinks dollar-for-dollar as your SSDI rises, because SSDI counts as unearned income against SSI. Most concurrent beneficiaries end up with a combined payment near the SSI federal benefit rate.

What health insurance comes with each program in Maryland?

SSI gets you Maryland Medicaid the day your benefit starts. SSDI gets you Medicare, but only after a 24-month wait. That gap is one of the biggest practical differences between the two programs, and it matters a lot if you need ongoing care.

SSI recipients in Maryland are enrolled in Medicaid automatically from the date SSI begins. No separate application. Maryland's Medicaid program (called Maryland Medical Assistance) covers doctor visits, hospital stays, prescriptions, mental health services, and long-term care. ^[6] For someone with no work history and no current insurance, that coverage is worth a lot.

SSDI recipients get no automatic Medicaid. They qualify for Medicare instead, but there's a 24-month wait. You have to receive SSDI for two full years before Medicare kicks in. ^[1] During those two years, you're on your own for coverage unless you qualify for Medicaid another way. Maryland does have income-based Medicaid rules that some SSDI recipients meet, so check with the Maryland Department of Health or HealthCare.gov during that stretch.

When Medicare finally starts, SSDI recipients usually get Part A (hospital) free and pay a premium for Part B. In 2025, the standard Part B premium is $185/month. ^[8]

People on concurrent SSI and SSDI often carry both Medicaid and Medicare. Once both are active, out-of-pocket costs can drop to almost nothing.

Does Maryland add anything extra beyond the federal programs?

Maryland's main add-on is the state SSI supplement covered above. Past that, a few state-level details are worth knowing.

Maryland runs a federally supervised disability determination process. The Disability Determination Services (DDS) office in Maryland, operating under an SSA contract, makes the medical decisions on initial applications and reconsiderations. It sits in Baltimore. ^[9] DDS requests your medical records, may schedule consultative exams, and issues the initial determination. SSA's federal offices in Maryland handle payment and eligibility.

Maryland also has local SSA field offices where you can apply or get help. The main ones sit in Baltimore, Towson, Bethesda, Silver Spring, Annapolis, and other cities. Find the nearest office at SSA.gov. ^[1]

Beyond disability checks, Maryland runs programs like the Energy Assistance Program (MEAP), which helps with utility bills, and Temporary Cash Assistance for families. SSI recipients often qualify for SNAP automatically in Maryland under broad-based categorical eligibility, though the details depend on your household. ^[6]

Who qualifies for both SSI and SSDI at the same time in Maryland?

Concurrent eligibility is real and fairly common. You can collect both when your SSDI benefit is low enough that adding SSI still keeps you under the SSI income rules. Workers with thin or interrupted earnings records are the usual candidates.

Here's the math. Say your SSDI payment is $600/month. SSA counts that as income against your SSI, but the first $20 of any income is excluded, so it counts $580. Your 2025 SSI maximum is $967. Subtract $580 from $967, and you'd get about $387 in SSI on top of your $600 SSDI. Combined: roughly $987/month, plus Maryland's small supplement.

This comes up for people with interrupted work histories, folks who worked for years, became disabled, but never earned enough in their peak years to build a real SSDI benefit. It also hits people who became disabled young, before they built up much of an earnings record.

SSA's POMS (Program Operations Manual System) section SI 00830.300 spells out how SSDI benefits count as unearned income against SSI. ^[2]

If you might qualify for both, apply for SSI when you apply for SSDI. SSA sorts out which benefits you get. There's no penalty for filing for both.

How do you apply for SSI or SSDI in Maryland?

The application is federal, not state-specific. You apply through SSA no matter which program you want. For SSDI, you can do most of it online. For SSI, expect an interview.

For SSDI, apply online at SSA.gov, call SSA at 1-800-772-1213, or walk into any Maryland field office. ^[1] The online SSDI application is reasonably complete and doable in one or two sittings.

SSI is more involved. SSA usually requires an interview for SSI because the financial eligibility check needs documentation of income, assets, and living arrangements. You can start online with a pre-screening questionnaire, but count on an in-person or phone appointment somewhere in the process. ^[2]

For both programs, pull these together before you apply: Social Security number, birth certificate or proof of age, medical records with doctor names and addresses, work history for the last 15 years, most recent W-2 or tax return, and bank account info for direct deposit. For SSI, also gather bank statements, car title, and paperwork on any other assets.

The initial decision takes about three to six months in Maryland, though it varies. Most initial applications are denied. SSA's data shows roughly 67% of initial SSDI claims get turned down. ^[9] If yours does, you can request reconsideration and then an ALJ hearing. Don't quit after the first denial.

If you want to get organized before you start, DisabilityFiled's guided intake walks you through the same information SSA asks for and builds a claim summary you can bring to SSA or a representative.

Does the 5-month waiting period apply to SSI in Maryland?

No. The five-month waiting period only applies to SSDI. SSI has none. That single difference can move real money in the first months after approval.

With SSDI, even after SSA approves you, you get nothing for the first five full months of your disability. If SSA decides your disability began January 1, your first SSDI payment covers June. ^[7] This is statutory under 42 U.S.C. § 423(a)(1). The five months cannot be waived.

SSI has no equivalent wait. Once you're approved, payments can start as early as the month after you filed, or the month after you became eligible, whichever is later. ^[2]

The difference shapes your back pay. SSDI back pay can reach up to 12 months before your application date, subject to your established onset date and the five-month rule. SSI back pay starts only from your application date. So if approval takes two years, the back pay can be sizable, but it's calculated differently for each program.

For more on the five-month rule and how it hits your back pay, see Social Security Disability 5-Year Rule.

Can you work part-time while receiving SSI or SSDI in Maryland?

Both programs let you work some, but the rules aren't the same. SSDI has a hard cliff at the SGA threshold. SSI phases your benefit down gradually instead of cutting it off.

For SSDI, the number that matters is Substantial Gainful Activity. Earn more than $1,620/month gross in 2025 and SSA presumes you can work, which puts your SSDI at risk. There's a Trial Work Period that lets you test work for up to nine months without losing benefits, and an Extended Period of Eligibility after that. But once you consistently clear SGA, SSDI stops. ^[4]

SSI is more forgiving in some ways. SSA excludes the first $65 of earned income each month, then counts only half of everything above that. Earn $400/month and SSA counts just $167.50 against your SSI. Your benefit drops by that $167.50 rather than vanishing. This is the earned income exclusion. ^[2]

SSA also runs a Student Earned Income Exclusion for SSI recipients under 22 who attend school regularly. In 2025, they can exclude up to $2,290/month (up to $9,230/year) in earnings with no SSI reduction. ^[2]

Maryland layers no extra state work incentives on top of these federal rules. But Work Incentive Planning and Assistance (WIPA) programs operate in Maryland to help beneficiaries understand their own situation. Find a WIPA counselor through SSA's Benefits.gov or by calling 1-800-772-1213.

How does the appeals process work in Maryland if you're denied?

About 67% of initial SSDI claims get denied. ^[9] Don't read that as the end. In Maryland, the road from denial to approval runs through the standard federal four-step process, and most people who win do it at the hearing stage.

Step 1 is Reconsideration. A different SSA examiner reviews your file. Maryland does run reconsideration (some states piloted a process that skipped it; Maryland is not one of them). Roughly 85 to 90% of reconsideration requests are also denied, so most people move on.

Step 2 is an ALJ Hearing. An Administrative Law Judge holds a hearing, usually by phone or video in Maryland, though in-person is available. The ALJ reviews all the evidence and may bring in a vocational expert. This is where most approvals happen for people who stick with it. ALJ approval rates have historically run around 50 to 55% nationally. ^[9]

Step 3 is the Appeals Council, if the ALJ denies you. The Council checks ALJ decisions for legal or procedural errors. Most review requests get denied without a full look.

Step 4 is federal district court. In Maryland that's the U.S. District Court for the District of Maryland (D. Md.), which covers the whole state.

Legal representation clearly improves your odds at the ALJ stage. SSDI attorneys work on contingency and can charge at most 25% of back pay up to $7,200 (the cap as of 2024, adjusted periodically by SSA). ^[1] For help finding representation, see SSDI Lawyer: How to Find and Work with a Disability Attorney.

Is SSDI taxable in Maryland?

Federally, up to 85% of your SSDI can be taxed. In Maryland, most disabled workers pay no state tax on it at all. The state exempts Social Security and SSDI income for taxpayers under certain income thresholds.

At the federal level, up to 85% of your SSDI benefit may be taxable if your "combined income" (adjusted gross income + nontaxable interest + half of Social Security benefits) tops $25,000 for an individual or $32,000 for a couple. ^[10] Below those numbers, SSDI is not taxed federally.

Maryland state tax works differently. Maryland exempts Social Security benefits, including SSDI, from state income tax for most taxpayers. As of 2025, Maryland gives a full exemption for Social Security and SSDI income to taxpayers with federal adjusted gross income under $75,000 (individual) or $100,000 (joint). ^[11] Higher earners may owe some Maryland tax, but most disabled workers sit well below those cutoffs.

SSI payments are never federally taxable and never subject to Maryland income tax. ^[2]

For a full breakdown of federal taxation rules, see Is SSDI Taxable?.

How do SSI and SSDI payments get delivered in Maryland?

SSA pays both programs electronically. Direct deposit to a bank or credit union account is the default. No bank account? SSA can load payments onto a Direct Express prepaid debit card. ^[12] New recipients don't get paper checks.

SSDI payments arrive on a schedule tied to your birthday: the second, third, or fourth Wednesday of the month, depending on whether your birthday lands in the 1st-10th, 11th-20th, or 21st-31st. People who were already on SSDI before May 1997 get paid on the 3rd of the month. ^[1]

SSI payments go out on the 1st of the month for that month. If the 1st is a weekend or holiday, payment comes the prior business day. ^[2]

For current schedules, see SSDI Payment Schedule 2025, and for debit card and direct deposit options see SSI and SSDI Debit Cards and Direct Deposit.

Frequently asked questions

Can I get both SSI and SSDI in Maryland at the same time?

Yes. It's called concurrent benefits. It happens when your SSDI payment is low enough that adding SSI still keeps you under the SSI income limit. SSA counts your SSDI as unearned income against SSI, so your SSI drops dollar-for-dollar after a $20 exclusion. Combined, you'll generally land near the SSI federal benefit rate of $967/month plus Maryland's small state supplement.

What is the SSI resource limit in Maryland in 2025?

The limit is $2,000 for an individual and $3,000 for a couple. These are federal limits; Maryland does not raise them. Your primary home, one vehicle used for transportation, and certain other items are excluded from the count. These limits haven't changed since 1989, which makes them genuinely restrictive for anyone trying to keep even modest savings.

Does Maryland have a state supplement to SSI?

Yes. Maryland pays a small state supplement on top of the federal SSI payment. It ranges from roughly $10 to $23/month depending on your living arrangement and is administered by the Maryland Department of Human Services alongside the federal SSA payment. It won't dramatically change your budget, but Maryland residents do receive slightly more than the federal SSI floor of $967/month.

How long does it take to get approved for SSDI or SSI in Maryland?

Initial decisions typically take three to six months. Most first applications are denied, around 67% for SSDI nationally. If you appeal to an ALJ hearing, the total time from application to hearing decision often runs 18 to 36 months. Getting organized with complete medical records before you apply, and working with a representative from the start, tends to speed things up and improve your odds.

Do I get Medicaid automatically with SSI in Maryland?

Yes. Maryland SSI recipients are enrolled in Maryland Medicaid (Medical Assistance) automatically, starting the month their SSI begins. No separate application. SSDI recipients do not get automatic Medicaid; they qualify for Medicare after a 24-month waiting period. During that gap, you may qualify for Medicaid separately based on income.

What is the SSDI five-month waiting period and does it apply in Maryland?

The five-month waiting period is a federal SSDI rule under 42 U.S.C. § 423. You get no SSDI payments for the first five full calendar months of your disability period, regardless of when you apply. It applies equally in every state, Maryland included. SSI has no equivalent waiting period. SSDI back pay is calculated after accounting for this five-month offset.

Can I earn any income while receiving SSI in Maryland?

Yes. SSA excludes the first $65 of monthly earned income, then reduces your SSI by 50 cents for each dollar above that. So part-time work is allowed without wiping out benefits. Earn $300/month and SSA counts $117.50 against your SSI, cutting your payment by that amount but not ending it. Maryland has no state-level rules that change this calculation.

Is SSDI back pay larger than SSI back pay in Maryland?

Usually yes, for two reasons. SSDI monthly payments are generally higher (averaging $1,580/month vs. up to $967/month for SSI), and SSDI back pay can reach up to 12 months before your application date if you delayed applying, subject to your onset date and the five-month offset. SSI back pay starts only from your application date. For someone waiting two years to be approved, SSDI back pay can hit tens of thousands of dollars.

What happens to my SSI if I move out of Maryland to another state?

The federal SSI payment of up to $967/month stays the same nationwide. What changes is the state supplement. Some states pay more than Maryland's small supplement; some pay nothing. You must tell SSA about your move. Your new state's DDS office takes over the case, and the state supplement adjusts to whatever the new state pays. The medical eligibility decision itself does not restart.

Can a child receive SSI in Maryland?

Yes. Children under 18 can receive SSI if they have a severe medical or mental impairment and their family's income and resources fall under SSA's limits. The disability standard for children differs from adults; SSA looks at whether the impairment causes marked and severe functional limitations. The parent's income is "deemed" to the child's SSI calculation, which often reduces or eliminates the benefit for families with moderate earnings.

Does Maryland Medicaid cover people who get SSDI but don't yet have Medicare?

Potentially yes. Maryland Medicaid has income-based eligibility pathways that may cover SSDI recipients during the 24-month Medicare waiting period if their income and household size qualify. SSDI itself counts as income in this calculation. You'd apply through Maryland Health Connection (the state's ACA marketplace) or directly with the Maryland Department of Health. It's worth applying; coverage during that gap can matter a lot.

Is there a difference in how Maryland processes SSDI vs SSI applications?

The medical determination is handled the same way for both programs by Maryland's Disability Determination Services office in Baltimore, under SSA's federal contract. The difference is the financial review. SSI requires a more detailed look at income, assets, and living situation, which usually means an in-person or phone interview with SSA. The SSDI financial review is simpler, mostly confirming your work credit record.
