Does Maryland Tax Social Security Disability Benefits?

Maryland is one of the more tax-friendly states for SSDI recipients — but "tax-friendly" doesn't mean "tax-free for everyone." Whether your disability benefits are taxed in Maryland depends on a combination of federal rules, state rules, and your own income picture.

How Federal Taxation of SSDI Works First

Before state taxes even enter the picture, the federal government may tax a portion of your SSDI benefits depending on your "combined income" — a figure the IRS calculates by adding your adjusted gross income, any nontaxable interest, and half of your Social Security benefits.

For married couples filing jointly, those thresholds shift to $32,000 and $44,000. These are federal thresholds — Maryland then layers its own rules on top.

Maryland's Approach to SSDI Taxation

Here's the short answer: Maryland does not tax Social Security benefits — including SSDI — at the state level.

Maryland law explicitly exempts Social Security benefits from state income tax. That exemption applies regardless of how much you receive in SSDI, and regardless of whether the federal government taxes a portion of your benefits. Even if the IRS requires you to report up to 85% of your benefits as federal taxable income, Maryland does not follow suit. The state starts its income calculation in a way that effectively removes Social Security income from the equation.

This is a meaningful distinction. Some states conform closely to federal tax treatment, meaning if the federal government taxes your SSDI, the state does too. Maryland is not one of those states.

What Maryland Does Tax — and Why It Still Matters

Just because SSDI itself isn't taxed in Maryland doesn't mean every SSDI recipient has zero Maryland tax liability. Other income sources are still fair game. 🔎

Income that Maryland does tax includes:

• Wages or self-employment income (relevant if you're working within SSDI's trial work period or substantial gainful activity limits)
• Pension and retirement income (partially — Maryland offers deductions here, but they're not unlimited)
• Investment income, including dividends, capital gains, and interest
• Withdrawals from traditional IRAs or 401(k)s

If you're collecting SSDI and also drawing from a retirement account, receiving a part-time paycheck, or earning rental income, those other sources could generate a Maryland tax bill — even though the SSDI portion itself remains exempt.

The Interaction Between Federal and State Taxation 💡

This is where people often get confused. Consider a scenario where a recipient receives SSDI and also has wages from a trial work period or a spouse's income pushes combined household earnings higher. The federal government may require that up to 85% of the SSDI benefit be included in federal adjusted gross income (AGI).

When Maryland calculates your state tax, it subtracts Social Security benefits from your income before applying state rates. So even if your federal return shows SSDI as partially taxable income, Maryland's tax calculation removes it. You're not simply copying your federal taxable income onto your state return and calling it done — Maryland makes its own adjustments.

This matters practically: a household that owes federal income tax on SSDI benefits may still owe zero Maryland state tax on those same benefits.

SSI vs. SSDI: Does the Distinction Matter for Taxes?

Yes, though the outcome is the same in Maryland. SSI (Supplemental Security Income) is a needs-based federal program; it is never taxed federally or by any state. SSDI (Social Security Disability Insurance) is the work-credit-based program that can be federally taxable at higher income levels — but is still exempt under Maryland state law.

If you're uncertain which program you're on, the simplest indicator is your benefit letter from SSA or the program name on your bank deposits. The two programs have different eligibility rules, different payment structures, and different interactions with earned income — but for Maryland state tax purposes, both are exempt.

Local Taxes in Maryland

Maryland is unusual in that it has a county-level income tax in addition to the state income tax. These local rates vary by county and are collected through the same state income tax return. The good news: the Social Security exemption that applies at the state level also carries through to the local income tax calculation. SSDI benefits aren't taxed at the county level either.

Factors That Shape Your Overall Tax Picture

Even with SSDI exempt from Maryland taxes, several variables determine what a recipient's actual tax situation looks like:

• Filing status (single, married filing jointly, head of household)
• Other household income — wages, pensions, investment returns
• Whether you're in a trial work period and earning wages while collecting SSDI
• Age — Maryland offers additional income deductions for residents 65 and older
• Disability-related deductions you may qualify for at the federal level
• Whether you receive both SSDI and SSI, which affects total benefit amounts

These factors don't change the SSDI exemption itself — but they shape everything around it.

What Changes Annually

The federal combined income thresholds ($25,000 / $34,000 for single filers) have not been indexed to inflation, which means more recipients become subject to federal taxation over time as benefit amounts increase with annual cost-of-living adjustments (COLAs). Maryland's exemption, by contrast, is a flat exclusion — it doesn't phase out at higher income levels the way some other states' exemptions do.

The mechanics of how your total income interacts with those federal thresholds will shift year to year as your SSDI benefit adjusts with each COLA.

Maryland's rule is clear: SSDI benefits are exempt from state income tax. What remains variable is the full income picture surrounding those benefits — and that picture looks different for every recipient.
