In Maryland, properties are assessed at 100% of their market value, meaning the assessed value equals the market value. For example, if your home's market value is $432,000 (the county's median), at Maryland's 100% assessment ratio your assessed value would be $432,000, resulting in approximately $4,190 in annual taxes at the county's effective rate of 0.97%.

Frequently Asked Questions

What is the deadline to appeal my property taxes in Anne Arundel County?

You must file your property tax appeal within 45 days from the date printed on your assessment notice from the Maryland Department of Assessments and Taxation. This deadline is strictly enforced, and late appeals are typically not accepted. Since Maryland reassesses properties every three years on a rotating schedule, you'll only receive a new assessment notice every third year unless there's been a change to your property.

How do I file a property tax appeal in Anne Arundel County online?

To file online, visit https://assessmentappeals.dat.maryland.gov and enter your notice number and control number from your assessment notice. The online system allows you to submit your appeal, upload supporting documentation, and track your appeal status. You'll need to clearly state why you believe your assessment is incorrect and provide evidence such as comparable sales data or documentation of property condition issues. The online portal is available 24/7 during the appeal period.

What is the homestead exemption worth in Anne Arundel County?

The Anne Arundel County Homestead Tax Credit limits annual taxable assessment increases to just 2% for county taxes, one of the most generous caps in Maryland. This means if your property value increases by 10%, you'll only pay county taxes on a 2% increase that year. For state taxes, the cap is 10%. You must file a one-time application at https://onestop.md.gov to receive this credit, and it only applies to your principal residence.

What happens at a Property Tax Assessment Appeals Board hearing in Anne Arundel County?

At a PTAAB hearing, held at the Arundel Center at 44 Calvert Street in Annapolis, you'll present your case before a three-member board. You should bring all supporting evidence including comparable sales, photos, appraisals, and repair estimates. The hearing is informal but you should be prepared to clearly explain why your assessment is incorrect. The board will review your evidence, may ask questions, and will issue a written decision typically within 30-60 days after the hearing.

How much can I save by appealing my property taxes in Anne Arundel County?

While results vary, successful property tax appeals in Maryland save homeowners an average of $700 annually according to industry data. With Anne Arundel County's median annual tax bill of $3,719, even a 10% reduction in your assessed value could save you approximately $370 per year. Since reassessments occur every three years, these savings can compound over time. The key to a successful appeal is providing strong evidence that your property is overvalued compared to similar properties in your area.

What evidence do I need for an Anne Arundel County property tax appeal?

For a successful appeal, gather at least 3-5 recent sales of comparable properties in your neighborhood that sold for less than your assessed value, focusing on homes of similar size, age, and condition. Include clear photos documenting any property defects, outdated features, or needed repairs that affect value. A professional appraisal, while not required, can be compelling evidence. Also bring any documentation showing errors in your property's description, such as incorrect square footage or room count listed in the assessment.

Can I appeal my Anne Arundel County property taxes if I missed the 45-day deadline?

Unfortunately, the 45-day appeal deadline from your assessment notice date is strictly enforced by Maryland law, and late appeals are generally not accepted. However, if you discover a clerical error (like wrong square footage or property classification) or if your property suffers substantial damage, you may be able to request a revision outside the normal appeal period. Contact the Supervisor of Assessments office at(410) 974-5709 to discuss your specific situation and any available options.

Do I need to hire a lawyer for my property tax appeal in Anne Arundel County?

You are not required to hire a lawyer or professional representative for your property tax appeal in Anne Arundel County. Many homeowners successfully represent themselves, especially at the initial assessor review level. The process is designed to be accessible to property owners, and the hearings are informal. However, if your case involves complex valuation issues, commercial property, or if you're appealing to the Maryland Tax Court after unsuccessful lower-level appeals, professional representation may be beneficial.
