Property Tax Exemptions You're Probably Not Claiming in Maryland

Maryland's homestead credit gets talked about like a straightforward exemption, but it isn't one. It's a cap on how fast your taxable assessment can rise, which means it does nothing at all if property values in your area are flat. And you don't file it with your county the way most people assume; it goes to the state directly, and skipping that step means getting nothing, no matter how many years you've owned the home.

The cap that only helps when values are rising

The Homestead Tax Credit limits how much your home's taxable assessment can increase in a single year, capped at 10% statewide, though individual counties and cities can and do set their own, lower caps: Baltimore City at 4%, Prince George's County at 3%, Anne Arundel County at 2%. Reassessments happen on a three-year cycle, and any increase from a reassessment gets phased in evenly over those three years before the annual cap even applies on top of that. In a market where values are climbing, this can meaningfully soften what would otherwise be a sharp jump in your bill. In a flat or slow market, it provides no benefit at all, since there's no increase for it to cap.

Here's the part that catches people off guard: this requires a one-time application filed with the State Department of Assessments and Taxation, not your county. Maryland actually audited eligibility between 2012 and 2014 and removed thousands of homeowners who had lived in and owned their homes for years but had simply never filed the application. Owning and occupying your home isn't enough on its own. Confirm the credit is actually on file with SDAT, not just assumed.

The separate, income-based credit that needs yearly attention

The Homeowners' Property Tax Credit works on a completely different basis: your income relative to your tax bill, regardless of how your assessment has moved. Unlike the Homestead Credit's one-time filing, this one requires reapplying every year, with an October 1 deadline, though applying by April 15 is worth doing since it lets the credit apply directly to your July tax bill instead of arriving later as a refund. If your only income is Social Security, a pension, or an annuity, Maryland lets you apply just once every three years instead of annually, though you'll still need to certify your income each year in between.

The one that replaces the growth cap with a full exemption

Veterans certified by the VA as completely and permanently disabled receive a full exemption from real property tax on a single residential property they own and occupy, not a capped assessment, the entire tax bill. This one is also administered directly by the state, filed once, and generally continues until your status changes. Surviving spouses of qualifying veterans, and separately, surviving spouses of service members killed in the line of duty, can also qualify. One honest caveat worth knowing: this exempts you from property tax specifically, not from other charges on your bill like solid waste fees, which you'll still owe.

A few counties offer more, on top of all this

Maryland doesn't have a statewide senior exemption beyond the general growth cap, but several counties layer their own senior tax credit on top. Prince George's County, for instance, offers a 20% county-portion credit for homeowners 65 and older who meet income limits, and similar local programs exist in Montgomery, Howard, Anne Arundel, and Baltimore counties, each with its own rules. Check with your specific county; there's no statewide standard to rely on here.

What to actually check

Confirm your Homestead Tax Credit application is actually on file with SDAT, not just assumed from years of ownership. If you qualify for the income-based Homeowners' Property Tax Credit, file by April 15 to get it applied to your summer bill, and remember it needs yearly attention unless your income is exclusively Social Security or pension-based. And ask your county specifically whether it offers an additional senior credit on top of the state programs.
