Baltimore County tax records show who owns a property, what the county has assessed it at, what’s owed, and whether the bill has been paid. You can pull them up at mytax.baltimorecountymd.gov using a street address or account number, or request certified copies in person from the Office of Budget and Finance in Towson. The records are maintained by that office and reflect the county’s real property tax rate of $1.10 per $100 of assessed value, layered on top of a Maryland state rate of $0.112 per $100.1Baltimore County Government.

What Shows Up on a Baltimore County Tax Record
A tax record opens with the current owner’s name and a legal description of the property. The assessment is broken into land value and improvements, and that combined figure drives the tax calculation. Each levy is listed on its own line: the county rate, the state rate, and any special district charges tied to the parcel. Water and sewer charges calculated from meter readings also appear on the same statement.
Every property carries an account identifier assigned by the Maryland Department of Assessments and Taxation (SDAT). You’ll need that identifier to search online efficiently or to order certified copies.3Maryland Department of Assessments and Taxation. Finding Your Property Information Online
Searching the Online Portal
The county’s portal at mytax.baltimorecountymd.gov lets you look up any parcel, see the current balance, and pay. Have the exact street address or account number ready. Searching by street name alone returns a broader list, and a house number cuts that down quickly. You can filter by tax year to review past bills or check what’s coming due.
If the portal doesn’t return what you expect, cross-check the property through SDAT’s free Real Property Search.4Maryland Department of Assessments and Taxation. Real Property Most mismatches trace back to a recent ownership transfer or a misspelled name in one of the databases. Confirming the correct account identifier through SDAT and retrying the county portal resolves most search issues.
Deadlines on the Record
Annual tax bills and the first installment of semi-annual bills are due on or before September 30 and become delinquent on October 1. The second semi-annual installment is due by December 31 and goes delinquent on January 1.5Baltimore County Government. New Tax Bill Frequently Asked Questions These dates don’t shift for weekends or holidays. If your mortgage lender escrows your taxes, the lender pays directly, but you can still sign into the portal to confirm the payment posted.
Paying the Bill
The portal accepts electronic checks and credit or debit cards. An e-check costs $0.95 per transaction. Credit and debit payments carry a fee of 2.39% of the total charge.6Baltimore County Government. Payment Options On a $4,000 bill, the card fee adds roughly $96, so the e-check is dramatically cheaper.
Save the confirmation receipt the portal generates. Payments can take two to five business days to post and update the public search results, so an outstanding balance showing the next morning isn’t cause for alarm.6Baltimore County Government. Payment Options
You can also pay in person Monday through Friday, 8:00 a.m. to 4:30 p.m., at the Office of Budget and Finance, 400 Washington Avenue, Room 150, in Towson.7Baltimore County. Office of Budget and Finance Mailed checks work too; include the payment stub and mail early enough for the payment to arrive before the deadline.
What Happens if You Miss the Deadline
Interest and penalties accrue at 1% per month on any unpaid balance, starting the first day the payment goes delinquent.5Baltimore County Government. New Tax Bill Frequently Asked Questions On a $5,000 balance, that’s $50 the first month and another $50 every month after.
If the balance remains unpaid past December 31, the property becomes eligible for the county’s annual tax sale, which is advertised once a week for four consecutive weeks in advance.8Baltimore County. Tax Sale Investors bid on tax lien certificates at the sale, not on the property itself. The winning bidder pays off the delinquent taxes and gains the right to collect that amount, plus interest and fees, from the owner.
The owner can still reclaim the property by paying the certificate holder everything owed plus the buyer’s costs. For non-owner-occupied residential properties, the certificate holder can file to foreclose as early as four months after the sale. For owner-occupied homes, that wait is seven months.9Maryland General Assembly. Maryland Tax – Property Code 14-843 – Plaintiff or Holder of Certificate of Sale If the owner doesn’t redeem during that window and loses the foreclosure case, they can lose the property outright.
Credits and Exemptions That Reduce the Record
Several programs lower what a Baltimore County homeowner owes, and most require an application filed before the tax year begins.
Homestead Tax Credit
Maryland caps how much your assessed value can rise each year for tax purposes. The statewide ceiling is 10%; Baltimore County sets a tighter cap of 4%.2State of Maryland Department of Assessments and Taxation. 2025-2026 Tax Rates and Homestead Credit Caps If a reassessment jumps your value 15%, the county can only tax you on a 4% increase that year, with the rest phased in later. You must file a one-time application with SDAT to get the benefit. Without it, excess assessment increases hit your bill at full value.
Homeowners’ Tax Credit
This income-based credit is separate and requires a new application every year. To qualify for 2026, combined gross household income for 2025 must not exceed $60,000, and net worth (excluding the home and retirement accounts) must be under $200,000. The property has to be your principal residence, meaning you live there more than six months of the year.10Maryland OneStop. Homeowners Property Tax Credit Application Form 2026 Applications filed before April 15, 2026, are credited directly to the July tax bill. Applications are accepted through October 1, but late filers get a refund check instead of a reduction.
Disabled Veteran Exemption
Veterans with a permanent 100% service-connected disability rating from the U.S. Department of Veterans Affairs can receive a full property tax exemption on their primary residence and surrounding yard. The exemption extends to some surviving spouses, including spouses of service members who died in the line of duty.11Maryland General Assembly. Maryland Tax – Property Code 7-208 – Dwelling House of Disabled Veteran The dwelling must be occupied by no more than two families and must be the veteran’s legal residence. Apply through SDAT to activate it.
Appealing the Assessment
If the assessment on your record looks too high, you have 45 days from the date on your assessment notice to file an appeal. The process runs through three levels, and you don’t need an attorney for the first two.
- Supervisor’s level. An informal hearing with a local assessor, usually about 15 minutes. You explain why the value is wrong; the assessor walks through how the number was calculated. Bring comparable sales or evidence of property condition issues. Most disputes end here.
- Property Tax Assessment Appeals Board (PTAAB). If the supervisor’s hearing doesn’t resolve it, you have 30 days from the final notice to appeal to PTAAB, an independent board of local residents. More structured, still relatively informal.
- Maryland Tax Court. A formal legal proceeding where most homeowners bring an attorney. Both sides exchange evidence, and the court’s decision can be appealed to Circuit Court.
Once the 45-day window closes, you’re stuck with that assessment until the next triennial cycle. Filing at the supervisor’s level costs nothing and preserves your right to escalate.
Getting Certified Copies
Mortgage closings, title insurance applications, and legal proceedings usually require certified copies rather than a screenshot from the portal. The Office of Budget and Finance at 400 Washington Avenue, Room 150, in Towson issues these.7Baltimore County. Office of Budget and Finance Bring the legal description or account identifier so staff can pull records that may not be on the public site, including historical payment data going back multiple years. Requests can be made in person during business hours or by mail; confirm the current fee before sending anything, because incomplete requests can hold up a closing during peak real estate season.
