Prince George's County, Maryland Property Tax Appeal Guide 2027

Prince George's County property assessment appeals for tax year 2027

Prince George's County real property assessments are administered by the Maryland State Department of Assessments and Taxation (SDAT), not by a separate county assessor. For the regular 2027 reassessment cycle, the first filing is a Supervisor's-level SDAT appeal after receipt of a Notice of Assessment. SDAT says the first filing may be submitted online with the notice control number or by returning the paper appeal form, and that appeals must be filed within 45 days of the notice date.

Key 2027 dates

For this Prince George's County planning page, the estimated regular notice date is December 30, 2026 and the estimated deadline is February 13, 2027. The legal deadline is controlled by the actual notice date printed on the assessment notice, not by this planning estimate. If the notice date differs, count 45 days from that date.

Maryland values real property on the date of finality. For this 2027 policy label, TaxSauce uses January 1, 2027 as the target valuation date. Maryland law provides that real property is valued once in each three-year cycle, with the date of finality for the new value being the January 1 immediately before the first taxable year to which the new assessment applies.

Official appeal body and later review

The first level is the Supervisor's level. SDAT describes it as informal and says the hearing is conducted with an assessor designated by the Supervisor of Assessments. If the owner disagrees with the Supervisor's-level final notice, the next filing can go to the Property Tax Assessment Appeals Board within 30 days from the date of the Supervisor's-level final notice.

Prince George's County also lists a Property Tax Assessment Appeals Board for further hearings involving value, classification, increases, reductions, abatements, or refusals to increase, reduce, or abate an assessment. Prince George's County Property Tax Assessment Appeals Board

What to challenge

Use the official reason that matches the facts:

• Total New Market Value Does Not Reflect Market Value: Use this when recent arms-length sales of similar properties, the subject sale, or an appraisal supports a lower fair market value as of January 1, 2027.
• Mathematical Errors or Inaccurate Property Characteristics: Use this when SDAT's worksheet has value-affecting factual or math errors, such as incorrect enclosed area, land area, year built, quality, condition, baths, fireplaces, garage, or other physical characteristics.
• Classification Incorrect: Use this when the assessment classification or subclassification is wrong under Maryland assessment law, rather than when only market value is disputed.
• Income Method / Income-Producing Property Evidence: Use this for income-producing property when the income approach is part of the challenge. Maryland requires income and expense information at the Supervisor's level to preserve an income-method challenge at later appeal levels.

Evidence that usually matters most

SDAT explains that comparable properties are recently sold properties similar to the property being appraised, and that closer similarity makes the sale price more representative. SDAT's Area Sales Listing guidance also says customers can use the listing to compare their property with similar recently sold properties in the neighborhood or surrounding area, and that the best evidence of market value is the subject sale price or sale prices of similar properties. SDAT Assessment Q&A SDAT Residential Area Sales Listing

For TaxSauce screening, use sales from January 1, 2024 through January 1, 2027 because Maryland reassesses on a three-year cycle and the target valuation date is January 1, 2027. Prefer arms-length sales in the same neighborhood or surrounding market area. Screen broadly within 5 miles when needed, then prioritize the most similar, most recent sales by property type, style, quality, year built, above-grade enclosed or living area, land area, condition, and location.

No Maryland or Prince George's County source in this policy set publishes a strict county-wide maximum distance, gross living area variance, lot-size variance, or fixed number of comparable sales for Supervisor's-level residential appeals. That is why TaxSauce treats distance and similarity thresholds as conservative preparation filters, not as official SDAT rules.

What to avoid relying on by itself

A higher tax bill, a large percentage increase, a prior assessment, or general frustration with government services is usually weaker than value evidence. SDAT says owners should decide whether to appeal based on whether the Total Market Value of the land and building together reflects the property's market value. SDAT Assessment Q&A

County-only tax sensitivity

The normalized county rate for this page is 1.00%. Prince George's County's FY 2027 budget forecast states that the FY 2026 and FY 2027 county real property tax rate remains $1.00 per $100 of assessable value. Prince George's County SAC Letter

As a rough county-only sensitivity, a $10,000 lower assessable value corresponds to about $100 before State, municipal, special district, service, credit, phase-in, Homestead, and parcel-specific adjustments. This is not a savings prediction. It is a simple way to understand the county-rate portion of the issue.

Filing checklist

Before filing, gather:

1. The Notice of Assessment, including notice date, control number, account number, and Total New Market Value.
2. The SDAT appeal form or online filing information.
3. A short statement explaining which official issue applies and why.
4. Comparable-sale details, including address, sale date, sale price, property type, size, age, condition, location, and adjustments for differences.
5. Photos, contractor notes, permits, sketches, or records supporting condition issues or worksheet errors.
6. For income-producing property, income and expense statements for the previous three calendar years if the income method is part of the challenge.

SDAT says the first filing can be made online using the control number from the notice or by returning the paper form to the local assessment office. SDAT Assessment Appeal Process
