Baltimore County tax records are public documents that show who owns a parcel, its assessed value, the current tax bill, and whether anything is owed. You can search them for free at mytax.baltimorecountymd.gov using a street address or account number, and the county’s Office of Budget and Finance issues certified copies when you need them for a closing or legal matter. The county real property tax rate is $1.10 per $100 of assessed value, with a Maryland state rate of $0.112 per $100 added on top.1Baltimore County Government.

What’s in a Baltimore County Tax Record
A tax record opens with the current owner’s name and a legal description of the property boundaries. Assessment values are split between land and improvements, and the combined figure is the base the county uses to calculate your bill. Each levy is itemized: 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 statement.
Every property carries an account identifier made up of a county code, district code, subdivision number, and account number. The Maryland Department of Assessments and Taxation (SDAT) assigns these identifiers, and you’ll need yours to search records online or request certified copies.3Maryland Department of Assessments and Taxation.

How to Search Tax Records Online
Baltimore County’s portal at mytax.baltimorecountymd.gov lets you look up any parcel’s tax record, view the current balance, and make a payment. Searches work best with an exact street address or account number. A street-name-only search will pull a broader list of matches, so adding the house number saves time. You can also filter by tax year to check past obligations or upcoming deadlines.
If the portal doesn’t return what you expect, cross-reference the property through SDAT’s free Real Property Search tool.4Maryland Department of Assessments and Taxation. Real Property Mismatches usually trace back to a recent ownership transfer or a misspelled name in the state database, and confirming the correct account identifier through SDAT before retrying the county portal clears up most of them.
Getting Certified Copies or Historical Records
Mortgage closings, title insurance applications, and legal filings typically call for certified copies rather than a screenshot. The Office of Budget and Finance at 400 Washington Avenue, Room 150, in Towson issues these authenticated documents.5Baltimore County. Office of Budget and Finance Bring or send the property’s legal description or account identifier so staff can pull records that may not be available on the public portal, including payment history going back several years.
You can submit requests in person during business hours or by mail. If you mail yours, include a self-addressed stamped envelope for the return documents and confirm the current fee before sending. Incomplete requests slow things down, and during peak real estate season those delays can hold up a closing.
Paying a Tax Bill and Key Deadlines
Annual bills and the first installment of semi-annual bills are due on or before September 30 and become delinquent October 1. The second semi-annual installment is due by December 31 and becomes delinquent January 1.6Baltimore County Government. New Tax Bill Frequently Asked Questions These dates do not shift when they land on a weekend or holiday. If your mortgage lender escrows taxes, the lender handles payment directly, but you can still log in to confirm the bill was paid.
The portal accepts electronic checks and credit or debit cards. An e-check costs $0.95 per transaction. Credit and debit card payments carry a fee of 2.39% of the total charge, which gets expensive fast on a large bill. After submitting a transaction, save the confirmation receipt. Payments can take two to five business days to post, so a balance still showing the next day isn’t a sign something went wrong.7Baltimore County Government. Payment Options
In-person payments are accepted at the Office of Budget and Finance Monday through Friday from 8:00 a.m. to 4:30 p.m.5Baltimore County. Office of Budget and Finance You can also mail a check with the payment stub from your bill; allow enough lead time to arrive before the deadline.
What Happens If the Bill Goes Unpaid
Missing a deadline triggers interest and penalties of 1% per month on the unpaid balance, starting the first day the payment becomes delinquent.6Baltimore County Government. New Tax Bill Frequently Asked Questions A balance still unpaid after December 31 becomes eligible for the county’s annual tax sale, which is advertised once a week for four consecutive weeks beforehand.8Baltimore County. Tax Sale At the sale, investors bid on tax lien certificates rather than the property itself. The winning bidder pays off the delinquent taxes and earns 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 all taxes owed plus the buyer’s costs. For non-owner-occupied residential properties, the certificate holder can file a foreclosure action as early as four months after the sale; for owner-occupied homes, that timeline extends to seven months.9Maryland General Assembly. Maryland Tax – Property Code 14-843 – Plaintiff or Holder of Certificate of Sale An owner who doesn’t redeem during that window and loses the foreclosure case can lose the property entirely.
Credits That Reduce the Bill
Several programs can lower what you owe. Most require an application filed well before the tax year starts, so checking your eligibility now matters more than reading about them when the bill arrives.
Homestead Tax Credit
Maryland caps how much your assessed value can rise each year for tax purposes. The statewide ceiling is 10%, but 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 receive the credit. If you’ve never filed one, any excess assessment increases are hitting your bill at full value.
Homeowners’ Tax Credit
This income-based program is separate from the Homestead Credit and requires a new application each year. To qualify for 2026, combined gross household income for 2025 cannot exceed $60,000, and net worth (excluding the home and retirement accounts) must be under $200,000. The property must 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 submitted before April 15, 2026, will have the credit applied directly to the July tax bill. The program accepts applications through October 1, but filing late means a refund check instead of a bill 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 also extends to surviving spouses under certain conditions, 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. An application filed through SDAT activates the exemption.
Appealing Your Assessment
If you believe your property is assessed too high, Maryland gives you 45 days from the date on your assessment notice to file an appeal. The process has three levels, and you don’t need a lawyer for the first two.
The first level is an informal supervisor’s hearing with a local assessor, typically about 15 minutes. You explain why you think the value is wrong and the assessor walks you through how the number was calculated. Comparable sales data and evidence of property condition issues carry the most weight here, and most disputes get resolved at this stage. If the outcome isn’t in your favor, you have 30 days from the final notice to appeal to the Property Tax Assessment Appeals Board (PTAAB), an independent board of local residents that runs a more structured hearing. The final level is the Maryland Tax Court, a formal legal proceeding where you’ll likely want an attorney; its decision can itself be appealed to the Circuit Court.12Maryland Department of Assessments and Taxation. Assessment Appeal Process
The biggest mistake homeowners make is letting the 45-day window close without acting. Once it passes, you’re locked into that assessment until the next triennial cycle. Even if you’re unsure the appeal will succeed, filing at the supervisor’s level costs nothing and preserves your right to escalate.
