Search a Maryland Parcel Through SDAT, Then Open the Map or Tax Record You Actually Need
Maryland is easier to search than many states because the State Department of Assessments and Taxation (SDAT) maintains a statewide Real Property Data Search covering all 23 counties and Baltimore City.
Start with SDAT when you need the property account number, owner shown on the assessment record, land and improvement values, sales information, assessment history or Homestead status. For parcel mapping, tax-map layers and location research, Maryland Department of Planning’s FINDER Online is the better tool.
Maryland parcel search: go directly to your task
SDAT, Planning, local tax offices and land-record systems do different jobs. Use the right one from the start.
Quick answer: use SDAT first, not a third-party parcel website
Use SDAT Real Property Data Search.
Use FINDER Online or Maryland’s official tax-map and parcel GIS resources.
SDAT can display the owner name associated with the last recorded deed.
Use Maryland Land Records or the appropriate land-record system rather than treating an assessment record as title evidence.
Use the county or Baltimore City tax-billing and collection office.
SDAT handles the first-level assessment appeal. The normal notice appeal deadline is 45 days.
real-property assessment is administered by a state agency rather than by separate county assessors. SDAT values property statewide, while counties and municipalities apply their tax rates and collect the resulting taxes.
How to search Maryland SDAT property records
Use the Maryland.gov/SDAT system. Avoid websites that charge simply to show assessment information that SDAT provides publicly.
Maryland’s database covers 24 assessment jurisdictions: 23 counties plus Baltimore City.
SDAT supports address, street-name, Property Account Identifier and map-reference searches.
Address searching is stricter than an ordinary Google search, so remove street directions and suffixes when SDAT instructs you to do so.
Match the premises address, account number, legal-description clues, map reference and property characteristics.
Use FINDER for maps, local government for a tax balance, land records for deeds or SDAT appeal resources if the market value is disputed.
SDAT added a device-verification step to the Real Property Search in April 2026. When you open the application, complete the verification and allow the system to redirect you to the search page.
SDAT address-search rules that save a lot of failed searches
SDAT’s address search is not designed like a general web search. Maryland publishes specific formatting instructions, and following them can be the difference between finding the parcel immediately and getting no match.
Search issue |
SDAT guidance |
Example approach |
|---|---|---|
Street direction |
Do not enter North, South, East, West or directional abbreviations. |
Use the core street name first. |
Street suffix |
Do not enter Street, Avenue, Road, Way or their abbreviations. |
Search “Preston” rather than “Preston Street.” |
Exact street search |
Enter the complete street name for an exact search. |
Use PRESTON when that is the complete street name. |
No exact result |
SDAT allows a truncated street-name search using an asterisk. |
Try a partial name followed by * when the exact search fails. |
Owner name |
SDAT does not offer owner-name as a search method. |
Start with address, account identifier or map reference. |
ZIP code / subdivision |
You cannot search by ZIP code, town, neighborhood or subdivision. |
Choose the jurisdiction and use an allowed search field. |
if someone gives you an address containing a directional and suffix, simplify it before assuming SDAT has no record. “123 North Main Street” may need to be searched using only the number and core street name according to SDAT’s instructions.
Maryland Property Account Numbers are better than addresses for repeat research
Once you find the correct parcel, save its Property Account Number (PAN). SDAT defines the PAN as the real-property district code plus the account identifier assigned by the Department.
The account commonly includes a two-digit district code plus a six-digit account identifier.
Its account structure is different and includes district, subdivision and account components.
Property identification uses ward, section, block and lot components rather than the ordinary county format.
SDAT says letters shown after the Property Account Identification Number are for internal use and are not part of the actual property account number.
Deleted property accounts cannot be found with the ordinary search methods. SDAT states that a deleted account must be searched by its Property Account Identifier.
What a Maryland SDAT property record can show
A Real Property record contains far more than a single dollar value. The exact fields vary by property type and jurisdiction, but these are among the most useful items to inspect.
Record field |
What it means |
What to check |
|---|---|---|
Owner name |
Name shown from the last recorded deed information used by SDAT. |
Do not treat it alone as a current title opinion. |
Premises address |
Physical property address associated with the assessment account. |
Separate this from the owner’s mailing address. |
Property Account Number |
SDAT’s account identifier for the property. |
Save it for FINDER, tax-credit and assessment-office questions. |
Map / grid / parcel reference |
Location references associated with Maryland tax mapping. |
Use them to move from the record to mapping tools. |
Land use |
SDAT property-use category such as residential, commercial, industrial or agricultural. |
Make sure the classification fits the actual property. |
Land value |
Market-value component attributed to the land. |
Compare current and prior cycle information where displayed. |
Improvement value |
Value attributed to buildings and other taxable improvements. |
Review building facts if this amount seems inconsistent. |
Total market value |
SDAT’s estimate of fair market value. |
This is the main valuation figure to focus on in an assessment appeal. |
Sales data |
Recorded sale information associated with the parcel. |
A transfer can be non-market, so do not assume every sale is a valid comparable. |
Homestead status |
Shows whether SDAT has a Homestead Tax Credit eligibility application on file. |
Important for a principal-residence assessment cap. |

Maryland tax maps and parcel maps: what they actually show
Maryland Department of Planning’s Parcel Data & Mapping unit maps tax-assessment account locations and publishes parcel points, digital tax maps, tax-map grids, sales information and real-property characteristics in GIS-compatible formats.
Combine SDAT assessment data with Maryland Department of Planning location information.
Graphic assessment maps showing parcels in relation to adjoining property.
Show the boundaries and IDs of Maryland tax maps.
GIS polygon data can help with location and spatial analysis but is not a survey product.
Maryland explicitly states that tax maps are not legal descriptions, are not survey products and should not be used to design or construct improvements or determine floodplain status.
Maryland Department of Planning does not produce the same tax-map product for Baltimore City. Baltimore City maintains its own property-location map resources.
Use FINDER Online when you need the map rather than just the assessment record
FINDER Online is Maryland Department of Planning’s statewide tax-map and real-property viewer. It can search by address or parcel account ID and is useful for moving from an SDAT record into geographic context.
The official guide links directly to the current viewer.
FINDER supports location and account-based searches.
Maryland recommends including the two-digit county code.
Tax maps, property sales, parcel points and other information may require selecting the relevant map layer.
Confirm the account number and premises information before relying on the mapped parcel.
tax-map links from SDAT now route into Maryland Department of Planning’s FINDER Online. The account identifier may be prefilled, but you may still need to activate the appropriate map layers.
SDAT owner information is useful, but a deed answers a different question
SDAT defines the owner name as the name appearing on the last recorded deed used for the assessment record. That makes it useful for property research, but an assessment database is not the same thing as a title search.
Assessment owner name, property account, value, land/building facts and sales information.
Recorded deeds, mortgages, releases and other instruments when the legal document itself matters.
Different systems can update on different schedules. If SDAT still shows an earlier owner after a recent closing, verify the recorded deed before assuming the conveyance failed.
Maryland assessment value is an estimate of current fair market value
SDAT appraises real property at fair market value. Local governments then apply their property-tax rates to the applicable assessment when calculating the tax bill.
Uses relevant market sales to estimate what similar property would sell for.
Considers land and the cost of improvements, adjusted for depreciation and other factors.
Commonly relevant to income-producing property and considers its income-generating capacity.
do not focus only on the percentage increase from the old value. Maryland’s appeal process focuses on whether the new total market value is correct.
Maryland reassesses property on a three-year cycle
Maryland has more than two million real-property accounts divided into three reassessment groups. SDAT reviews approximately one-third of the properties in every jurisdiction each year, so an individual parcel is normally reassessed once every three years.
when a regular reassessment raises value, Maryland generally phases that increase into the assessment in equal portions over the three-year cycle. A decrease is generally implemented fully in the first tax year.
What changed in Maryland’s 2026 reassessment
SDAT’s 2026 reassessment covered 789,178 Group 2 residential and commercial properties. Maryland reported that all 23 counties and Baltimore City experienced overall value growth, while the pace of growth slowed compared with recent reassessment years.
Residential and commercial accounts were included in the 2026 Group 2 reassessment.
SDAT reported using this number of sales in evaluating the 2026 Group 2 properties.
SDAT reported an increase in value for this share of Group 2 residential properties.
Reassessment statistics describe large groups of properties. Your parcel’s assessment depends on its own market area, characteristics and valuation evidence.
SDAT assesses the property; your local government bills the tax
Finding a Maryland assessment does not necessarily tell you the exact amount currently owed. The State establishes assessment values, then counties, Baltimore City and municipalities apply their applicable tax rates and issue or administer bills.

Check the SDAT record for Homestead Tax Credit status
Maryland’s Homestead Property Tax Credit limits the amount of assessment increase on which an eligible principal-residence owner pays state, county and municipal property taxes each year. This is an assessment-growth cap program, not the same program as Maryland’s income-based Homeowners’ Property Tax Credit.
Check the Homestead application or eligibility status shown with the property information.
Eligible homeowners can submit the one-time Homestead eligibility application.
The state recommends electronic filing for faster processing.
Eligibility generally remains while the dwelling continues to qualify as your principal residence.
SDAT lists 410-767-2165 and 1-866-650-8783 for the Homestead Tax Credit program.
Homeowners’ Property Tax Credit is separate—and its 2026 filing deadline has passed
Maryland’s Homeowners’ Property Tax Credit is an income-based program that can limit the property-tax burden for qualifying homeowners. Eligibility is based on program rules including household income and property use.
the 2026 Homeowners’ Property Tax Credit application filing deadline was October 1, 2026. That date has passed. Do not submit an old 2026 form expecting ordinary timely processing; check SDAT for the next available application cycle or any officially announced exception.
How to appeal a Maryland property assessment
Maryland provides several opportunities to challenge an assessment. The most common begins when a property owner receives a regular Notice of Assessment.
Stage |
Deadline / timing |
What happens |
|---|---|---|
Supervisor’s Level |
Within 45 days of the assessment-notice date |
First-level SDAT appeal; written, phone, video or in-person options are available. |
Petition for Review |
Available in non-reassessment years under Maryland’s statutory schedule |
Useful when circumstances after the last reassessment may have reduced property value. |
New-owner appeal |
Special rights can apply to qualifying purchases between January 1 and June 30 |
Allows a qualifying purchaser to request review under the applicable rules. |
PTAAB |
Within 30 days of the Supervisor’s Level final notice |
Independent Property Tax Assessment Appeals Board review. |
Maryland Tax Court |
After the applicable PTAAB decision under Tax Court rules |
Further administrative appeal. |
Micro-step appeal workflow
Record the notice date, old value, new total market value and filing instructions.
Check building area, year built, land information, use, sales and other facts for obvious errors.
Maryland’s Property Owner’s Bill of Rights provides access to the property’s assessment worksheet and area sales analysis without charge in connection with an appeal.
Do not build the case only around the size of the percentage increase or the amount of your tax bill.
Submit the appeal online using the control number from the notice or return the provided appeal form to the appropriate local SDAT assessment office.
If the Supervisor’s Level decision is still disputed, the PTAAB appeal generally must be filed within 30 days of the final notice.
SDAT specifically warns homeowners that it does not charge owners to obtain their property assessment worksheet or to file a property assessment appeal.
Common SDAT parcel-search problems and practical fixes
Complete the current device-verification step. SDAT introduced additional cybersecurity verification in April 2026.
External links into specific Real Property Search screens may no longer work. Start at the main SDAT Real Property Search page.
SDAT warns that Real Property Search may be unavailable before 7:00 a.m. for maintenance.
Remove directions and street suffixes and follow SDAT’s address-search format.
SDAT does not provide an owner-name search field. Use an address, property account identifier or map reference.
Deleted accounts are searchable only by Property Account Identifier.
Current tax-map links redirect into Maryland Department of Planning’s FINDER Online system.
Open the map-layer controls in FINDER and enable tax maps, sales, parcel points or other needed layers.
Check the recorded deed and allow for differences in update timing between record systems.
Stop at the GIS stage and obtain recorded plat/deed information or a professional survey instead of measuring from the online tax map.

Maryland parcel search FAQs
1. Where can I search Maryland property records for free?
Use the Maryland State Department of Assessments and Taxation Real Property Data Search. It provides statewide public assessment information for all 23 counties and Baltimore City.
2. Can I search Maryland SDAT records by owner name?
No. SDAT’s search instructions say the Real Property database cannot be searched by owner name, town, neighborhood, subdivision or ZIP code. Use an address, street name, property account identifier or map reference instead.
3. How should I enter a street address in the SDAT search?
SDAT advises users not to enter street directions such as North or West and not to include suffixes such as Street, Avenue or Road. Start with the core street name and follow the state’s formatting instructions.
4. What is a Maryland Property Account Number?
It is the real-property district code plus the account identifier assigned by SDAT. The structure differs in some jurisdictions, particularly Anne Arundel County and Baltimore City.
5. Where can I view a Maryland parcel or tax map?
Use Maryland Department of Planning’s FINDER Online and statewide property GIS resources. Current SDAT tax-map links also route users into FINDER Online.
6. Are Maryland tax-map parcel lines legal property boundaries?
No. Maryland Department of Planning says tax maps are assessment and location tools, not legal descriptions or survey products. Use recorded documents and a professional survey for an exact boundary.
7. How often does Maryland reassess real property?
Maryland uses a three-year reassessment cycle. More than two million property accounts are divided into three groups, with roughly one-third of each jurisdiction reviewed annually.
8. How long do I have to appeal a Maryland assessment notice?
A regular first-level reassessment appeal must generally be filed within 45 days of the date on the Notice of Assessment. A later appeal to the Property Tax Assessment Appeals Board generally must be filed within 30 days of the Supervisor’s Level final notice.
9. Is Maryland’s Homestead Tax Credit the same as the Homeowners’ Property Tax Credit?
No. The Homestead Tax Credit limits eligible assessment growth on a principal residence. The Homeowners’ Property Tax Credit is a separate income-based program that can reduce qualifying property-tax bills.
10. Why might SDAT Real Property Search not work early in the morning?
SDAT states that the Real Property Search may be unavailable before 7:00 a.m. for maintenance. The site also uses a device-verification step introduced in 2026, so complete that verification before troubleshooting the property search itself.

35% Ratio Sanity Check
Ohio law sets taxable value at 35% of market value. If yours is significantly higher, you're a strong BOR appeal candidate.
BOR Appeal Savings

BOR Deadline Countdown
MAR 31Ohio's statutory Board of Revision filing deadline is March 31 for the prior tax year. Miss it and you wait until next year — no extensions.
Verify with the official Ohio source
These calculators use the verified 2026 Ohio Department of Taxation amounts and statutory rules. For your exact bill, exemption status, and county-specific deadlines, always confirm with your county auditor and the Ohio Revised Code:
Estimates use Ohio's 35% statutory assessment ratio and effective tax rate tiers averaged across major Ohio counties. Your actual bill depends on local school levies, voted millage, inside vs. outside millage splits, House Bill 920 reduction factors (HB 920), and special assessments. The 2026 Homestead general amount ($29,000) and enhanced amount ($58,000) reflect HB 187 inflation indexing — your county auditor's office may show slightly different transitional figures.
