Official Montgomery County MD Property Record Sources
Montgomery County property research is easier when you separate tax billing, assessment, ownership records and parcel maps. A tax bill can show what is due, but it does not replace a deed. An SDAT assessment record can help identify the account and value, but the deed chain is found through land records. GIS maps can help you see parcel context, but they are not legal boundary surveys.

Maryland SDAT Assessment Records and Property Account Lookup
Maryland SDAT is the main state source for real property assessment information. It can help you confirm account identifier, assessment values, premises address, legal description, sales history and assessment details.
SDAT is especially useful for users searching “Montgomery County MD property records by address,” “Maryland property tax assessment,” “Montgomery County SDAT property lookup,” or “property account identifier Maryland.”
Open SDAT Real Property Search and select Montgomery County, then search by street/address details.
Use the account identifier when available because it gives a cleaner match than broad address text.
SDAT’s own guidance says the online system does not search by owner name, town, subdivision, neighborhood or zip code.
- Open the SDAT search page. Go to Maryland SDAT Real Property Search.
- Select Montgomery County. Choose Montgomery County before entering the property details.
- Use address, street name or account identifier. Enter only the cleanest details. Avoid extra punctuation or apartment/unit text unless needed.
- Copy the account identifier. Save the account identifier, premises address, legal description, assessment values and sale information.
- Compare with county tax records. Open Montgomery County Real Property Tax and compare the tax account/bill information.

The Montgomery County Real Property Tax portal is the correct official path for tax bills, balances, prior payment information and payment options. You can search by tax account number or street address.

Montgomery County MD Deeds, Mortgages, Plats and Land Records
For deeds and recorded property documents, use Maryland Land Records rather than the county tax bill page. Maryland Courts explains that deeds are public records and can be viewed online through MDLandRec after creating an account with the Maryland State Archives.
Use land records when you need deed history, ownership-transfer documents, mortgages, releases, easements, plats, refinance documents or recorded legal instruments. Use tax records when you need bill and payment information. Do not mix the two.
- Open Maryland Land Records. Go to MDLandRec.
- Create or sign in to your account. Maryland deed viewing may require a Maryland State Archives account before you can access documents online.
- Select Montgomery County. Choose Montgomery County land records before searching by party name, book/page, instrument number or record type.
- Search with deed clues. Use grantor/grantee names, recording date, deed reference, liber/folio, property address, account identifier or legal description clues.
- Use plats when a recorded map is needed. Open Maryland Plats.net for recorded plat image research when relevant.
MCATLAS, Property Map Viewer and GIS Parcel Maps
Montgomery County GIS tools help users see parcel location, property layers, roads, zoning/planning context, environmental layers and nearby features. GIS is useful for confirming location, but it does not replace the deed, plat, survey or legal description.
Open MCATLAS for interactive county map research and parcel context.
Open the Property Map Viewer to search by address and identify property information.
Use Montgomery Planning GIS for planning maps, data downloads and map viewers.
- Open MCATLAS or the Property Map Viewer. Start with MCATLAS when you need parcel location or map layers.
- Search by address. Enter the street address and select the matching parcel carefully.
- Compare with SDAT. Open SDAT Real Property Search and compare account identifier, address and property details.
- Compare with the tax bill. Use Montgomery County Real Property Tax for tax account and bill information.
- Use a survey for boundary issues. Do not use map lines as final proof for fences, easements, setbacks, construction, encroachment or legal boundary disputes.
Tax Credits, Mailing Address and Owner Information Checks
Many Montgomery County searches are really about tax credits, mailing address updates, ownership timing or assessment changes after a sale. These issues can involve more than one agency.
Use SDAT for assessment records and many property owner forms. Use Montgomery County Finance for bills and balances. Use MDLandRec for the recorded deed that supports ownership transfer history.
| User Question | Where to Start | What to Check |
|---|---|---|
| Why did my tax bill change? | County tax bill + SDAT | Assessment, tax year, charges, credits, prior balance and payment status. |
| Is my homestead or tax credit showing? | Maryland SDAT Real Property | Credit eligibility, application status, owner occupancy and account identifier. |
| Owner name looks outdated | MDLandRec | Recorded deed date, grantee name, SDAT update timing and tax account information. |
| Mailing address is wrong | SDAT forms/resources | Current mailing address, owner record, tax bill mailing address and required form. |
Assessment Appeal and Value Review Steps
If the assessment value seems wrong, start with SDAT rather than the tax payment page. SDAT is the assessment authority for Maryland real property. The county tax bill is based on assessment data, local rates and charges, but the value review path starts with SDAT.
- Open the SDAT record. Search the property at SDAT Real Property Search.
- Review assessment details. Check account identifier, premises address, legal description, sales, assessed value and assessment year.
- Identify the exact problem. Decide if the issue is value, property description, land data, building data, mailing address, credit status or ownership timing.
- Collect evidence. Useful evidence may include comparable sales, appraisal, photos, repair estimates, condition issues, incorrect square footage proof, deed details or survey information.
- Use official SDAT appeal guidance. Open Maryland SDAT Real Property and follow the current appeal or owner-form instructions.
