How Prince George's County Assesses Property

100%of market value

Assessed by: Maryland State Department of Assessments and Taxation (SDAT) - Prince George's County Assessment Office

Assessment cycle: triennial

Notices typically mailed: Late December (for reassessment years) or Spring (April-May for annual notices)

In Prince George's County, properties are assessed at 100% of their market value. The Maryland State Department of Assessments and Taxation reassesses all properties on a triennial (three-year) cycle. For example, if your home's market value is $345,300, at Maryland's 100% assessment ratio your assessed value would be $345,300, resulting in approximately $3,833 in annual taxes at the county's effective rate of 1.11%.

The Appeal Process

Appeals are heard by the Property Tax Assessment Appeals Board (PTAAB). At PTAAB hearings, you present your case to a board of local residents appointed by the Governor. You may appear in person, in writing, or through a representative. The hearing is informal, no fees are required, and you can present any evidence regardless of what was shown at the Supervisor's Level. You have the burden of proof to show SDAT's assessment is incorrect.

Review your assessment notice carefully and gather evidence supporting your belief that the assessed value is incorrect, including comparable sales data from similar properties in your area that sold within the past year.

File your appeal within 45 days of the assessment notice date either online at https://assessmentappeals.dat.maryland.gov/ using your control number, by mail to the Prince George's County Assessment Office at 14735 Main Street, Suite 356B, Upper Marlboro, MD 20772, or in person during business hours.

Choose your hearing preference: written appeal (submit all evidence with your appeal form), phone hearing (you'll be notified of the date and time), or video hearing via Google Meet (requires email address for meeting link).

Attend the Supervisor's Level hearing with SDAT where you'll present your evidence, including comparable property sales, photos of property condition issues, repair estimates, or a professional appraisal. SDAT will provide a property worksheet and comparable sales list before your hearing.

If dissatisfied with the Supervisor's Level decision, appeal to the Property Tax Assessment Appeals Board (PTAAB) within 30 days of receiving your final notice. PTAAB hearings allow you to present new evidence and are conducted by local residents appointed by the Governor.

If still dissatisfied after PTAAB, appeal to the Maryland Tax Court within 30 days of the PTAAB decision. This is a de novo hearing where you must appear in person, and no fees are required to file.

For properties not in a reassessment year, file a Petition for Review by the first working day following January 1 for the upcoming tax year beginning July 1, particularly if events have occurred that decreased your property value since your last assessment.

Required form: Petition for Review (SDATRP_EX-4A) or online appeal form

Frequently Asked Questions

What is the deadline to appeal my property taxes in Prince George's County?

You must file your property tax appeal within 45 days from the date printed on your assessment notice from the Maryland State Department of Assessments and Taxation (SDAT). For properties reassessed in the 2026 cycle, the deadline is approximately February 13, 2026, though the exact date depends on when your specific notice was issued. If you miss this deadline, you can still file a Petition for Review by the first working day following January 1 for the next tax year beginning July 1. It's critical to mark your calendar immediately upon receiving your assessment notice to avoid missing this important deadline.

How do I file a property tax appeal online in Prince George's County?

You can file your property tax appeal online at https://assessmentappeals.dat.maryland.gov/ using the control number found on your assessment notice. The online portal allows you to submit your appeal electronically and choose whether you want a written review, phone hearing, or video hearing via Google Meet. You'll need to enter your county (Prince George's), notice number, and control number from the top and bottom of page 1 of your assessment notice. After submitting, you can upload supporting documents such as comparable sales data, photos, and repair estimates. The online system is available 24/7 and provides confirmation of your filing.

What is the Homestead Tax Credit worth in Prince George's County?

The Homestead Tax Credit in Prince George's County limits the annual increase in your taxable assessment to just 3% at the county level for FY2026, plus an additional 10% cap at the state level. This means even if your property's market value increases significantly during a reassessment year, your taxable assessment for county purposes can only go up by 3% annually if you have the Homestead Credit. For example, if your previous taxable assessment was $300,000, it could only increase to $309,000 for county tax purposes regardless of market value increases. You must occupy the property as your principal residence and apply through SDAT to receive this credit.

What happens at a Property Tax Assessment Appeals Board (PTAAB) hearing in Prince George's County?

At a PTAAB hearing, you present your case to a board of local Prince George's County residents appointed by the Governor. The hearing is informal and you can appear in person, submit a written appeal, or send a representative. You'll have the opportunity to present any evidence supporting your position, including comparable sales, appraisals, photos, and repair estimates—even evidence not presented at the earlier Supervisor's Level hearing. The SDAT assessor will also present their evidence. You'll need to bring four copies of your presentation materials: three for the board members and one for the assessor. PTAAB hearings are de novo, meaning they review the case fresh without being bound by the prior decision. No fees are required to file a PTAAB appeal.

How much can I save by appealing my property taxes in Prince George's County?

The savings from a successful property tax appeal in Prince George's County depends on how much your assessment is reduced. With an effective tax rate of 1.11%, every $10,000 reduction in assessed value saves you approximately $111 annually in property taxes. For example, if you successfully appeal and reduce your assessment from $350,000 to $320,000—a $30,000 reduction—you would save approximately $333 per year. Over a three-year assessment cycle, that totals nearly $1,000 in savings. Given that the median home value in the county is $345,300 and the median tax bill is $3,870, even a modest 5-10% assessment reduction can result in hundreds of dollars in annual savings, making the appeal process worthwhile for many homeowners.

What evidence do I need for a successful property tax appeal in Prince George's County?

To build a strong property tax appeal in Prince George's County, you need evidence proving your property's assessed value exceeds its true market value. The most compelling evidence is comparable sales data from similar properties in your neighborhood that sold within the past year for less than your assessment. You should gather at least three to five comparable sales showing lower values per square foot. Additional supporting evidence includes a professional appraisal dated close to the January 1 assessment date (must be provided to SDAT at least 10 days before your hearing), photographs documenting property defects or condition issues, contractor estimates for needed repairs, and for income-producing properties, three years of income and expense statements. SDAT will provide you with their own comparable sales list before your hearing, which you should review carefully.

When does Prince George's County reassess property values?

Prince George's County properties are reassessed by the Maryland State Department of Assessments and Taxation (SDAT) on a triennial cycle, meaning each property is reassessed once every three years. Maryland divides all properties into three geographic groups, and one group is reassessed each year. If your property was reassessed for the 2027 tax year, you received a notice in late December 2026. Assessment notices are typically mailed in spring (April-May) each year, though full reassessment notices come in December. The assessed value is based on the property's market value as of January 1 and applies to the tax year beginning the following July 1. You can check your property's next reassessment date by contacting the Prince George's County Assessment Office or checking your property record on SDAT's website.

Can I appeal my Prince George's County property taxes if I just bought the property?

Yes, if you purchased property in Prince George's County between January 1 and June 30, you can file a New Owner Appeal within 60 days from the date of transfer (the date your deed was recorded). This special appeal allows new owners to challenge the assessment even outside the normal 45-day appeal window for assessment notices. You'll need to complete the Petition for Review form (SDATRP_EX-4A), check the "New Owner Appeal" box, and submit it to the Prince George's County Assessment Office along with a copy of your recorded deed. This is particularly valuable if you believe you overpaid for the property or if market conditions have changed since January 1. Note that your purchase price itself may be used by SDAT as evidence of market value, so you'll need strong comparable sales data if your appeal is based on a lower valuation.
