Baltimore County wraps around Baltimore City on three sides, and people confuse the two all the time. They’re separate jurisdictions with separate tax bills, separate offices, and separate tax sale calendars. A seller in Towson, Catonsville, or Parkville is dealing with county rules, not city rules, even when the mailing address says “Baltimore.” Handling a Baltimore County sale on a Parkville or Carney house? See selling a house in Parkville. If the house is in 21222 or 21219 and you’re dealing with a Baltimore County sale, see my Dundalk, MD page.
I’m Evan Weissman. I buy houses across Baltimore County, from Dundalk and Essex to Owings Mills, Cockeysville, and the farm roads near Hereford and Upperco. This guide is the overview I’d give a county seller, with links to deeper articles on each topic.
One county government, no towns
Baltimore County has no incorporated cities or towns. Towson, Catonsville, Dundalk, Pikesville, and the rest are communities, not municipalities. That means every house in the county pays the same county property tax rate with no town tax layered on.
For 2026-2027, the SDAT tax rate table lists the county rate at 1.1000 per $100 and the state rate at 0.1120, for 1.2120 combined. The county’s homestead credit cap is 4%. A buyer starts without your capped assessment, so their tax estimate may be higher than your bill.
Deed taxes and the lien certificate
Baltimore County’s Budget and Finance pages list a county transfer tax of 1.5% and recordation tax of $2.50 per $500. Add the state transfer tax of 0.5%, or 0.25% for a first-time Maryland homebuyer.
On a $275,000 sale, before any exemptions:
- State transfer tax: $1,375
- County transfer tax: $4,125
- Recordation tax: $1,375
- Total: $6,875, or about $3,438 each under Maryland’s default equal split
The county also requires a lien certificate with any deed that transfers property, and deeds go through county tax review before Land Records will record them. If online tools are down, the county has pointed people to Taxpayer Services at 410-887-2416. My Baltimore County transfer and recordation article walks through that process step by step.
A late-summer tax sale
Most Maryland counties hold their tax sales in May or June. Baltimore County’s is later. SDAT’s schedule and county materials listed the 2026 sale for August 27. If you’re behind on taxes, that later date gives a little more room, but interest and costs keep growing in the meantime.
Start with Taxpayer Services and the State Tax Sale Ombudsman at (410) 767-4994. If the mortgage is behind too, talk with your servicer about loss mitigation, call a HUD-approved housing counselor or Maryland HOPE at 1-877-462-7555, and consider an attorney. Selling is one option among several. My article on foreclosure options lays them out.
Three kinds of county housing
The county isn’t one housing market. I tend to see three broad groups:
The older inner ring. Dundalk, Essex, Middle River, Parkville, Overlea, Catonsville, and Arbutus have lots of houses from the 1940s through the 1960s, including brick rowhomes, Cape Cods, and ranchers. Inspections there focus on aging roofs, electrical panels, oil heat, and basement water. My article on selling an older Baltimore County rancher covers that housing type.
Suburban subdivisions. Owings Mills, Perry Hall, White Marsh, Reisterstown, and Timonium have more homes from the 1970s on, often with HOAs. Buyers look at systems near the end of their life and HOA paperwork.
The northern county. Past the reach of public water and sewer, around Hereford, Parkton, Upperco, and the valleys, many homes rely on wells and septic. Maryland law requires most sale contracts on well properties to include a water quality test unless the buyer waives it in writing, and buyers usually ask for a septic inspection.
Waterfront and Critical Area questions
The county has a long tidal shoreline along Back River, Middle River, and the Chesapeake. Maryland requires most sale contracts to include a Critical Area notice, and lots within about 1,000 feet of tidal waters and wetlands may fall under extra rules on clearing and building. Flood zones matter in low-lying areas like Bowleys Quarters and Edgemere, and the state disclosure form asks about them.
Estates in Towson
The Baltimore County Register of Wills is in the County Courts Building at 401 Bosley Avenue, Room 500, in Towson, 410-887-6680, according to the Register of Wills site. A personal representative appointed there signs the deed for an estate sale. My page on selling an inherited house explains how I work with families, and selling before probate closes covers timing.

Picking between listing and a direct sale
Updated homes in popular parts of the county usually sell well on the open market, and I’ll tell you if yours is one of them. A direct sale tends to fit houses that need major work, rentals with tenants, estates, or septic and well problems a financed buyer may not take on. My Baltimore County page and the cash offer vs. listing page help you compare.
Is Baltimore County the same as Baltimore City?
No. They’re separate jurisdictions with different tax rates, transfer taxes, lien processes, and tax sale dates. Use the rules for wherever the land sits.
What is the transfer tax in Baltimore County?
The county transfer tax is 1.5%. The state transfer tax and recordation tax of $2.50 per $500 are added on top.
Does Baltimore County have any town taxes?
No. The county has no incorporated municipalities, so there’s no town property tax anywhere in the county.
When was the 2026 Baltimore County tax sale?
SDAT’s schedule and county materials listed August 27, 2026.
Where is the Baltimore County Register of Wills?
In the County Courts Building at 401 Bosley Avenue, Room 500, in Towson.
