How Anne Arundel County Assesses Property

100%of market value

Assessed by: Maryland State Department of Assessments and Taxation (SDAT) - Anne Arundel County Assessment Office

Assessment cycle: triennial

Notices typically mailed: Late December

In Maryland, properties are assessed at 100% of their fair market value. Anne Arundel County properties are reassessed once every three years as part of a statewide triennial cycle, with assessment notices mailed in late December. For example, if your home's market value is $467,900 (the county median), at Maryland's 100% assessment ratio your assessed value would be $467,900, resulting in approximately $3,977 in annual county and state property taxes at the combined effective rate of 0.85%.

The Appeal Process

Appeals are heard by the Property Tax Assessment Appeals Board (PTAAB). The PTAAB is a three-member board (with two alternates) that meets as needed at the Arundel Center, 44 Calvert Street, Room 163, Annapolis. Hearings typically involve presenting your evidence, including comparable sales and property condition documentation, and the board issues a written decision usually within two weeks.

1

Review your SDAT assessment notice received in late December and verify the assessed market value against comparable properties in your neighborhood that sold within the past year.

2

Gather evidence to support your appeal, including recent comparable sales data, professional appraisals, photographs documenting property condition, repair estimates for needed work, and any factors that negatively affect your property's value.

3

File your appeal within 45 days of the notice date using the online SDAT portal at assessmentappeals.dat.maryland.gov, by mail, or in person at the Anne Arundel County Assessment Office at 45 Calvert St., 3rd Floor, Annapolis.

4

Attend an informal review with the SDAT assessor at the local assessment office, where you will present your evidence and the assessor may agree to adjust the assessment without a formal hearing.

5

If the informal review does not resolve your appeal, your case will be scheduled for a hearing before the Anne Arundel County Property Tax Assessment Appeals Board (PTAAB) at 44 Calvert Street, Room 163, Annapolis, where a three-member board will review evidence and issue a written decision typically within two weeks.

6

If you disagree with the PTAAB decision, file a further appeal to the Maryland Tax Court within 30 days of receiving the board's decision.

7

As a final option, if the Maryland Tax Court decision is unfavorable, you may appeal to the Circuit Court following the procedures outlined in Maryland Tax-Property Article.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Anne Arundel County?
You have 45 days from the date printed on your SDAT assessment notice to file a property tax appeal in Anne Arundel County. Assessment notices are typically mailed in late December, which means the appeal deadline usually falls in mid-February, often around February 13 for most properties. If you miss the 45-day window after receiving a reassessment notice, you may still file a Petition for Review by the first business day after January 1st if you can demonstrate significant changes to your property value between reassessment cycles. It's critical to note the specific date on your notice and calculate the deadline from that date, not from when you received the notice in the mail.
How do I file a property tax appeal online in Anne Arundel County?
To file a property tax appeal online in Anne Arundel County, visit the Maryland State Department of Assessments and Taxation (SDAT) online portal at assessmentappeals.dat.maryland.gov. You will need your assessment notice number and control number, which are located at the top and bottom of page 1 of your assessment notice. The online form allows you to enter your property information, explain why you believe the assessed value is incorrect, and upload supporting documentation such as comparable sales data, photographs, and appraisals. The online system is available 24/7 and provides confirmation of your filing. You can also file by mail to 45 Calvert St., 3rd Floor, Annapolis, MD 21401, or in person during business hours Monday through Friday from 8:00 AM to 4:30 PM.
What is the Homestead Tax Credit worth in Anne Arundel County?
Anne Arundel County's Homestead Tax Credit caps annual increases in your property's taxable assessed value at just 2% per year, which is significantly lower than the state maximum of 10%. This means if your home's market value jumps from $350,000 to $400,000 in one reassessment year, the county would only tax you on a $357,000 assessment (a 2% increase) rather than the full $400,000 value. For a typical Anne Arundel County homeowner with a median-value home of $467,900, this credit can save hundreds or even thousands of dollars annually during periods of rapidly rising home values. You must file a one-time application with SDAT to establish owner-occupancy, after which it applies automatically every year you continue to occupy the home as your principal residence.
What happens at a Property Tax Assessment Appeals Board hearing in Anne Arundel County?
The Property Tax Assessment Appeals Board (PTAAB) hearing in Anne Arundel County takes place at the Arundel Center, 44 Calvert Street, Room 163 in Annapolis, Maryland. The hearing is conducted by a three-member board (with two alternates) who will review the evidence you present, which should include recent comparable sales data, professional appraisals, photographs of your property's condition, and any documentation showing errors in the assessment or factors that reduce your property's value. The hearing is typically informal but professional, and you'll have the opportunity to explain why your property's assessed value is too high. The board usually issues a written decision within two weeks of the hearing. If you're not satisfied with the board's decision, you have the right to appeal further to the Maryland Tax Court within 30 days.
How much can I save by appealing my property taxes in Anne Arundel County?
According to data from property tax appeal services, successful appeals in Anne Arundel County result in an average savings of approximately $650 annually. However, your actual savings depend on how much your assessed value is reduced and your property's tax rate. For example, if you successfully reduce your home's assessed value by $50,000, you would save approximately $425 per year based on Anne Arundel County's combined county and state tax rate of about $1.089 per $100 of assessed value. Nationwide statistics show that about 25% of homes are overassessed, and property owners who appeal have a significant chance of success, particularly when they provide strong comparable sales evidence showing their property is valued higher than similar homes in their neighborhood.
What evidence do I need for an Anne Arundel County property tax appeal?
To file a successful property tax appeal in Anne Arundel County, you need compelling evidence that your property's assessed value exceeds its actual market value. The strongest evidence includes recent comparable sales of similar properties in your neighborhood that sold for less than your assessed value (ideally within the past 6-12 months), a professional independent appraisal conducted by a licensed Maryland appraiser, and photographs documenting your property's condition, defects, or needed repairs. You should also gather repair estimates for any significant issues, documentation of assessment errors (such as incorrect square footage, wrong number of bathrooms, or inaccurate lot size), evidence of environmental issues or neighborhood problems affecting value, and market analysis showing declining property values in your area. The more documentation you provide showing your home is worth less than the assessed value, the stronger your case will be.
How does Maryland's triennial reassessment cycle affect Anne Arundel County property taxes?
Maryland reassesses all properties once every three years through a rotating triennial cycle managed by the State Department of Assessments and Taxation (SDAT). Anne Arundel County properties are divided into three groups, and each year one-third of properties receive a new assessment notice in late December. This means your property will be physically reassessed approximately every three years, regardless of whether market values have risen or fallen. Between reassessment years, your assessed value remains stable unless you make significant improvements requiring a building permit. When your home is reassessed, any increase in value is phased in over three years rather than applied all at once, providing some cushion against sudden tax increases. Combined with Anne Arundel County's 2% Homestead Tax Credit cap, this system helps protect homeowners from dramatic year-over-year tax bill increases even during periods of rapidly rising home values.
Can I appeal my Anne Arundel County property taxes in a non-reassessment year?
Yes, you can appeal your property taxes in Anne Arundel County even in years when you don't receive a reassessment notice by filing what's called a Petition for Review. The deadline to file a Petition for Review is the first business day after January 1st, though it's recommended to file well before then. A Petition for Review is most appropriate when significant events have occurred since your last regular triennial assessment that have caused your property value to decline, such as severe property damage, substantial structural issues, flooding or environmental problems, major increases in vacancy (for commercial properties), discovery of significant defects, or demonstrable inaccuracies in the assessment data. You'll need to provide strong evidence showing why your property's value has declined since the last assessment. This option is particularly useful for homeowners who purchased near the end of a reassessment cycle or who have experienced unexpected property damage or neighborhood changes.
