Baltimore County runs its tax sale later in the year than most of Maryland. In 2026 the auction was August 27, while many counties finished theirs in May or June. If you own a house in the county and your property taxes are behind, that schedule gives you a few extra weeks, but the steps leading up to the sale still move on a fixed calendar. If the house is in 21234 and you’re dealing with a Baltimore County tax sale notice, see selling a house fast in Parkville. If the house is in 21222 or 21219 and you’re dealing with a Baltimore County tax sale notice, see selling a house fast in Dundalk.
I’m Evan Weissman. I buy houses in Baltimore County, and part of what I do is help owners understand their options before a tax problem turns into a bigger one. This article walks through the county’s process using the county’s own published materials.
How a county bill becomes delinquent
According to the county’s tax sale page, real property tax bills go out July 1 each year. If you don’t pay in full, or don’t make the first semiannual payment by September 30 when you’re eligible for that plan, the account is delinquent and interest starts adding up.
Balances still unpaid after December 31 become subject to interest, penalties, and the tax sale. The county then mails a Final Tax Sale Notice that gives the owner 30 days to pay the taxes, interest, and penalties.
The payoff deadline before the auction
The county’s 2026 public notice set a deadline of Wednesday, July 31, 2026, at 4:30 p.m. for paying overdue taxes and charges by cash, certified check, or money order to keep a property out of the sale. Properties still unpaid were advertised once a week for four weeks in a local newspaper, and the list was posted on the county’s website.
The county also adds fees to each account in the sale, which it lists as $25 for postage and handling, $50 for advertising, and $15 for legal costs. Those are on top of the taxes and monthly interest.
What happens on sale day
The 2026 sale ran as an online auction. Registered bidders, often investors, bid on tax liens, not on the house itself. The winning bidder pays the county the overdue amount and gets the right to collect it back from you with interest. You still own the house, and you can still live there and sell it.
If a property sits on ground rent, the county sells only the leasehold interest. Liens that don’t sell at auction go to the county.
Redemption interest in Baltimore County
To redeem, you pay the amount the bidder paid for the taxes, plus interest, later taxes, and certain allowed expenses. The county’s materials aren’t entirely consistent on the rate. Its public notice cites 12% a year under the county code, while its collector’s terms cite 10%. Either way, state law caps redemption interest on owner-occupied homes at 10% a year.
State law also limits the expenses a certificate holder can add, and those limits get larger over time, especially once a foreclosure case is filed. My article on redeeming a property after a Maryland tax sale covers the fee limits in detail.
Redemptions go through the county Office of Budget and Finance at 400 Washington Avenue, Room 150, in Towson. The county’s tax sale line is 410-887-5616.
The months after the sale
The county’s tax sale page says an owner has six months from the sale to redeem before a foreclosure case to cut off redemption can be filed. Its collector’s terms say certificates of tax sale are usually mailed about six months after the sale for properties that aren’t owner-occupied and about nine months after for owner-occupied homes.
Once a foreclosure case is filed in the Circuit Court for Baltimore County, the cost to redeem goes up. If the court enters a final judgment, the right to redeem ends and the owner can lose the house, along with any equity in it. That’s why the period right after the sale matters.
Where to get help
Free help comes first. The State Tax Sale Ombudsman at (410) 767-4994 can explain your situation and point you to programs. Maryland’s Homeowner Protection Program is meant to help eligible owner-occupants keep their homes out of tax sale. The county’s Office of Budget and Finance can tell you exactly what you owe.
If a mortgage is behind too, call your servicer about loss mitigation, a HUD-approved counselor or Maryland HOPE at 1-877-462-7555, and an attorney. Some lenders pay overdue taxes to protect their lien, and that changes your options.
Selling when taxes are behind
Selling is one possible way out, not the only one. A sale can pay off the overdue taxes or the redemption amount from your proceeds at settlement, and you keep the rest of your equity. That can be done with a listing or with a direct buyer. My page on being behind on property taxes and my Baltimore County local guide explain how I approach it.
