Maryland Property Tax Due Dates 2026: When Bills Are Due

Maryland property tax due dates decide when you pay and when penalties start, so they are worth knowing cold. Miss one and interest and late fees pile up fast. This guide lays out the Maryland property tax due dates, when bills are mailed, and what to do if the bill looks wrong. If you pay through a mortgage escrow account, your lender usually handles the dates, but it is still

your job to make sure the bill is correct.

Maryland Property Tax Due Dates: When to Pay

Here are the Maryland property tax due dates. The tax year runs July 1-June 30. Bills are mailed in July and are due by September 30; owner-occupied homes may pay semiannually (first half by September 30, second half by December 31). Confirm with your county finance office.

Late taxes accrue interest and penalty. Many homeowners pay through a mortgage escrow account.

When Maryland Property Tax Bills Are Mailed

Counties mail bills in July after SDAT certifies assessments. If a bill does not arrive, do not assume you owe nothing — not getting a bill usually does not excuse a late payment. Contact your treasurer if you think a bill is missing, and keep your mailing address current with them. The mailing is your signal that the Maryland property tax due dates are close.

Paying Maryland Property Tax: Escrow vs. Paying Yourself

There are two common ways homeowners pay property tax. If you have a mortgage, your lender often collects a slice of the tax with each monthly payment, holds it in an escrow account, and pays the county for you when the bill comes due. That is convenient, but it is still worth checking your annual escrow statement — if your assessment jumps, your monthly payment can rise, and an error

in the assessment quietly costs you every month.

If you own your home outright or your loan does not escrow, you pay the county directly on the schedule above, so those Maryland property tax due dates are yours to track.

Either way, the responsibility to make sure the bill is correct is yours. Escrow only pays the number on the bill — it does not check whether that number is fair. That is why reviewing your assessment each year matters even when a lender handles the payment.

What If You Can’t Pay Your Maryland Property Tax on Time?

If money is tight, the worst move is to go silent. Unpaid property taxes add penalties and interest, and over time an unpaid balance can become a lien on your home and, eventually, a tax sale. The good news is that help usually exists if you ask early. Contact your county treasurer or tax collector before the Maryland property tax due dates hit and ask what is available — many

offer payment plans that spread the balance over several months.

Older homeowners and those on a fixed income should also look at the relief programs on our exemptions page — a homestead, senior, veteran, or disability break can shrink the bill, and some states let qualifying seniors defer payment until the home is sold. Acting early keeps you in control and out of the penalty spiral.

If Your Maryland Bill Looks Wrong

Paying on time and challenging an unfair value are two different things — and you should do both. Pay the bill as billed to avoid penalties, and separately, if the assessed value behind the bill is higher than what your home would sell for, you can appeal it. In Maryland, appeals are heard by SDAT supervisor (informal), then the Property Tax Assessment Appeals Board (PTAAB), then the Maryland Tax Court.

Note the deadline: Because the STATE (SDAT) does assessments, appeals go through SDAT: file a supervisor’s-level appeal within 45 days of the date on your Notice of Assessment; then PTAAB within 30 days; then the Maryland Tax Court within 30 days. A recent buyer can appeal within 60 days of purchase, and a mid-cycle ‘petition for review’ is due by the first workday after January 1. Confirm dates on your

notice.

Fixing an over-assessment is the most reliable way to bring the bill itself down for years to come.

Don’t want to appeal your Maryland taxes yourself? A property tax appeal service can file everything for you and usually only charges if it wins — typically a share of what it saves you. It is one option; you can also appeal on your own for free.
