The phrase “tax sale” makes a lot of people picture an auctioneer handing their house to a stranger. That’s not quite what happens in Maryland, at least not at first. At a county tax sale, the bidder buys a certificate tied to the unpaid taxes. The owner still holds title and still has a right to pay off the debt, called redemption, for a period after the sale.
I’m Evan Weissman. I buy houses in Maryland, and I talk with homeowners at every stage of this process. Here’s a plain explanation of how the system works, based on the State Department of Assessments and Taxation’s tax sale information page and Maryland law.
The three parties in a tax sale
It helps to know who’s involved:
- The county or Baltimore City tax collector. Each local government runs its own sale to collect overdue property taxes and certain other charges.
- The bidder. An investor or company that pays at the sale and receives a tax sale certificate.
- The owner. You keep title after the sale. What changes is that a certificate holder now has a claim that can lead to foreclosure if the property isn’t redeemed.
How taxes become overdue
Maryland property taxes are due July 1 and overdue on October 1, according to SDAT. If you pay a principal residence in two installments, those are due September 30 and December 31.
If the bill goes unpaid, the county moves toward its tax sale. SDAT says the owner gets a notice by mail at least 30 days before the property is advertised, and the property is then advertised for 4 consecutive weeks before the sale. Each county sets its own sale date. SDAT posts a schedule each year.
What the bidder actually buys
At the sale, bidders compete for certificates on individual properties. The winning bidder pays the taxes owed and receives a certificate of tax sale, which SDAT says is issued within about 6 months.
Think of the certificate as a claim against the property, not a deed. It gives the holder two possibilities:
- The owner redeems, and the holder is repaid with interest and certain allowed expenses, or
- The owner doesn’t redeem, and after a waiting period the holder can go to court to foreclose the right of redemption and eventually take title.
Most certificate holders are in it for the first outcome. They’d rather be repaid with interest than own the house.
Redemption: paying it off after the sale
Redemption means paying what’s owed to clear the certificate. That usually includes the taxes, interest at a rate set by law, and some of the holder’s expenses. The interest rate varies by county. A 2025 law, Chapter 231, caps the rate at 10% for owner-occupied homes starting January 1, 2026.
There’s a timing detail in SDAT’s guidance that’s useful to know. Expenses the certificate holder pays during the first 4 months after the sale aren’t reimbursable. Redeeming early keeps costs lower.
Redemption payments generally go through the county tax collector, not directly to the bidder. Ask the collector’s office for an exact figure good through a specific date. My article on redeeming after a tax sale walks through that step.
The foreclosure step and its timeline
If the property isn’t redeemed, the certificate holder can file a court case to foreclose the owner’s right of redemption. According to SDAT, the holder can file after 6 months from the sale, or after 9 months for an owner-occupied home. If the holder doesn’t file within 2 years, the certificate becomes void.
Even after a case is filed, the owner can usually still redeem until the court enters a final judgment, but the amount can grow as legal fees are added. If a final judgment is entered, the right to redeem ends and the holder can get a deed. That’s the point where the house can truly be lost, which is why acting early matters.
Help built into the system
Maryland has added protections over the years:
- The State Tax Sale Ombudsman at SDAT helps homeowners understand the process, their options, and their rights. The office can be reached at (410) 767-4994, or toll-free at (833) 732-8411.
- The Homeowner Protection Program, run through the Ombudsman, serves limited-income, elderly, and disabled homeowners at risk of losing a home to tax sale.
- Tax credits. SDAT runs a homeowners’ property tax credit for qualifying incomes, which can lower future bills.
My article on the State Tax Sale Ombudsman has more detail on what that office does.
Selling as one of several paths
For some owners, the most practical path is to pay the taxes, set up a plan with the county if one is offered, or use a credit program. For others, especially with an inherited or vacant house, selling makes more sense. A sale can happen before the tax sale or after it, as long as it closes before a final foreclosure judgment. The overdue taxes or redemption amount are paid from the sale proceeds at settlement, and the owner keeps the remaining equity.
If you want to explore that, my page on being behind on property taxes explains how I handle those sales. You may also want to read what happens at the auction if your county’s date is coming up.
Does a Maryland tax sale mean I lost my house?
No. The bidder receives a certificate, not your house. You keep title and generally have the right to redeem until a court enters a final foreclosure judgment.
How soon can a certificate holder foreclose in Maryland?
SDAT says the holder can file after 6 months from the sale, or 9 months if the home is owner-occupied. The certificate is void if they don’t file within 2 years.
Who do I pay to redeem my property?
Usually the county tax collector’s office. Ask for a written redemption figure good through a specific date.
Can I still sell after my house goes to tax sale?
Generally yes, as long as the sale closes before a final judgment. The redemption amount is paid from the proceeds.
Is the interest on a tax sale certificate capped?
For owner-occupied homes, a 2025 law caps the redemption interest rate at 10% starting January 1, 2026. Other rates vary by county.
