Property Tax in Frederick County, 2026

A calculator and field guide for Frederick-area homeowners — and for anyone considering a move to Frederick County — including Maryland's combined state + county property tax structure, the Homestead Tax Credit's county-set caps on annual taxable assessment growth (Anne Arundel 2%, Talbot 0%, most counties 5%, max 10%), the income-tested Homeowners' Property Tax Credit, and the constitutional 100% disabled veterans full exemption (Tax-Property §7-208).

Frederick County, home to Frederick and 295k Marylanders, operates under Maryland's combined state + county property tax system. Tax = Assessed Value × combined rate per $100 of AV. Assessments are conducted by the Maryland State Department of Assessments and Taxation (SDAT) every three years (Group 1, 2, or 3 cycles), with assessment increases phased in over 3 years. Maryland's 24 jurisdictions (23 counties + Baltimore City) each set their own county/city tax rate.

How the bill is built

Maryland property tax involves layered steps. Step 1: Full Cash Value. SDAT determines full cash value (= fair market value) every 3 years on a triennial cycle. Step 2: Phased-in Assessment. Increases in assessment are phased in evenly over 3 years (decreases applied immediately). Step 3: Apply state + county/city tax rates. State rate is $0.112/$100 statewide; county/city rates vary widely from ~$0.62 (Talbot) to ~$1.97 (Baltimore City). Frederick's combined rate is approximately $1.04/$100 of phased-in AV. Step 4: Apply Homestead Tax Credit cap. Annual taxable assessment growth is capped at the county-set rate (5% in Frederick County). Owner-occupants must file a one-time application with SDAT to establish eligibility.

Maryland's Homestead Tax Credit requires a one-time application — it's not automatic. Homeowners who fail to file with SDAT lose the cap-on-assessment-growth protection. The county's cap rate determines how aggressively annual assessment increases are limited. Check your status at the SDAT Real Property database.

Maryland 100% disabled veterans receive a FULL exemption (Tax-Property §7-208). Veterans declared by the VA to have a 100% service-connected permanent and total disability — or 100% individually unemployable — receive a complete exemption from real property taxes on their dwelling and curtilage. Surviving spouses retain the exemption (unmarried). Surviving spouses of US service members killed in line of duty also fully exempt. This is among the most-comprehensive disabled-veteran exemptions in the United States. Counties separately offer partial credits for 50%-99% disabled veterans (varies by county adoption — e.g., Anne Arundel offers 50% of county tax for 75%+ disability with income below $100K).

The Homeowners' Property Tax Credit caps tax as percent of income. Separate from the Homestead Tax Credit, Maryland's income-tested Homeowners' Property Tax Credit limits property tax to a sliding-scale percentage of household income. For 2026, applications are due by April 15 with income limits set at ~$60K for individuals or couples (some credit can extend higher). The program provided $63.9 million in credits statewide in fiscal year 2025. Many Maryland counties (including Baltimore City and Howard) provide a local supplement on top of the state credit.

As of April 26, 2026 · From Maryland State Department of Assessments and Taxation - Frederick.

Note: Frederick County is **western Maryland** at the foothills of the Catoctin Mountains — anchored by Frederick (~85K, the third-largest city in Maryland). The county is home to Camp David (the official US Presidential retreat, in the Catoctin Mountains, technically classified at NSA-Frederick), Fort Detrick (the US Army Medical Research Institute of Infectious Diseases — the only Biosafety Level-4 lab on a US military installation), and the National Cancer Institute at Frederick. The county is the historic location of multiple Civil War battles (Battle of Monocacy, July 1864 — "the battle that saved Washington DC").

Note: Frederick County effective property tax rates run approximately 1.04% — moderate by Maryland standards. Combined tax rate is approximately $1.04/$100 of phased-in AV. Frederick County sets a Homestead Tax Credit cap of **5%** on annual taxable assessment growth. Median home values around $440K combined with the moderate rate produce median annual bills around $4,576.

Note: For relocation buyers: Frederick County offers **the rural-suburban Maryland** option — historic downtown Frederick has one of the most-celebrated downtowns in the Mid-Atlantic (Bethesda Magazine and Travel + Leisure routinely rank Frederick among the best small towns in the Eastern US), strong Frederick County Public Schools, and reasonable commute to Montgomery County (Frederick to Bethesda ~45 min via I-270) and DC. The trade-off: longer DC commute than Montgomery, less commercial diversity. Camp David and the Catoctin Mountain Park provide federal-employee recreational connections that drive substantial second-home demand.

Deductions and exemptions for 2026

Maryland homeowner property tax relief is concentrated in four mechanisms: (1) the Homestead Tax Credit (county-set caps on annual taxable assessment growth), (2) the Homeowners' Property Tax Credit (income-tested, caps tax as percent of income), (3) county senior tax credits (typically ~20% of county tax for age 65+ with limited income), and (4) the constitutional 100% Disabled Veterans Real Property Tax Exemption (Tax-Property §7-208 — full exemption).

Homestead Tax Credit (county-set caps)

Maryland's Homestead Tax Credit caps annual taxable assessment growth on owner-occupied principal residences. State law caps the state portion at 10%; counties set their own (typically lower) caps for the county portion: Anne Arundel 2% (one of the most-protective in MD), Talbot 0% (the most-protective — AV essentially frozen), Prince George's / St. Mary's / Garrett 3%, Allegany / Baltimore City / Baltimore County / Cecil 4%, most others 5%, Charles 7%, Montgomery / Calvert / Somerset 10% (the state max). One-time application required (file with SDAT) — homeowners who fail to apply lose the protection. Check status at the SDAT Real Property database.

Homeowners' Property Tax Credit (income-tested)

The Homeowners' Property Tax Credit limits property tax to a sliding-scale percentage of household income. For 2026, applications are due by April 15 with income limits set at ~$60,000 for individuals or couples (some credit can extend higher). Up to ~$1,000+ in annual credits for income-qualified homeowners. The program provided $63.9 million in credits statewide in fiscal year 2025. Many Maryland counties (including Baltimore City and Howard) provide a local supplement on top of the state credit.

100% Disabled Veterans Exemption (Tax-Property §7-208)

Maryland provides a full real property tax exemption for veterans declared by the VA to have a 100% service-connected permanent and total disability OR 100% individually unemployable. The exemption applies to the dwelling and curtilage (lot and structures necessary to use the property as residence). Surviving spouses retain (unmarried). Surviving spouses of US service members killed in line of duty are also fully exempt. Apply with the local SDAT office with DD-214 + VA rating decision. Refunds available retroactive to VA rating effective date (up to 3 years). Counties separately offer partial credits for 50%-99% disabled veterans (varies by county adoption — e.g., Anne Arundel offers 50% of county tax for 75%+ disability with income below $100K).

Appealing your assessment

Frequently asked questions

When are Maryland property taxes due?

Maryland's property tax year runs July 1 through June 30. Bills are typically mailed in July. Owner-occupied primary residences can pay in two installments: September 30 (first half) and December 31 (second half), or pay the full bill by September 30 to avoid the second installment. Investment properties and commercial owners typically pay full bill by September 30. Late payments accrue interest plus penalty (1% per month typical). Most Maryland homeowners pay through escrow via mortgage servicer.

Do I have to apply for the Homestead Tax Credit?

Yes — the Homestead Tax Credit requires a one-time application with the State Department of Assessments and Taxation (SDAT). After the 2007 reform, owners who fail to apply lose the cap-on-assessment-growth protection (which can mean significant additional tax in counties with low caps like Anne Arundel's 2% or Talbot's 0%). Check your status at the SDAT Real Property database (look up your property → scroll to "Homestead Application Status"). If it says "No application," file the application immediately. Once approved, the credit applies as long as the property remains your principal residence — no annual renewal required.

What's the difference between Baltimore City and Baltimore County?

Maryland has an unusual jurisdictional structure: Baltimore City is an independent jurisdiction, NOT part of any county. The City of Baltimore was incorporated in 1729, separated from Baltimore County in 1851, and operates as its own first-level political subdivision (similar to the 38 independent cities in Virginia). Baltimore County (with its seat in Towson) is a wraparound suburban county surrounding the City. The two have separate governments, separate school systems, separate police departments, and separate tax bases. Baltimore City's effective tax rate (~1.97%) is much higher than Baltimore County's (~1.13%) — reflecting the City's smaller residential base relative to its service obligations. Maryland's other 23 jurisdictions are all counties.

How do I qualify for the 100% Disabled Veterans full property tax exemption?

Maryland's full disabled-veterans exemption (Tax-Property §7-208) requires: (a) honorable discharge from US military service, AND (b) VA-determined 100% service-connected permanent and total disability OR 100% individually unemployable rating. Apply with the local SDAT office using the Application for Exemption for Disabled Veterans, attaching DD-214 and the VA rating decision (which must reference the 100% P&T or unemployable rating, the rating decision date, and the disability effective date). The exemption applies to the dwelling, lot, and curtilage (structures necessary to use the property as residence). Surviving spouses (unmarried) retain. Refunds available retroactive to the VA rating effective date (up to 3 years pursuant to §7-208(g)). Counties separately offer partial credits for 50%-99% disabled veterans — see your county's tax credit program.

How does Maryland's triennial assessment cycle work?

Maryland reassesses property on a triennial cycle — Group 1, Group 2, or Group 3, with each group covering approximately one-third of properties. SDAT mails reassessment notices by January 1 of the assessment year. Increases in assessment are phased in evenly over the next 3 years, while decreases are applied immediately for the new tax year. For example: if 2026 reassessment shows a $360,000 home (up from $300,000 in 2023), the $60,000 increase is split into $20,000/year over 3 years (FY27, FY28, FY29). The Homestead Tax Credit's annual cap applies to each phased-in increment. Frederick County reassesses on a published group cycle — check the SDAT calendar for the next reassessment year.

How do I appeal my Maryland assessment?

Maryland property tax appeals follow a 3-tier process. Level 1: Local SDAT Office. File a written appeal within 45 days of the assessment notice. SDAT supervisors review and may adjust. Level 2: Property Tax Assessment Appeals Board (PTAAB). If denied, appeal to the county PTAAB within 30 days. PTAAB holds quasi-judicial hearings — present comparable sales, recent appraisals, or independent appraiser testimony. Level 3: Maryland Tax Court. PTAAB decisions can be appealed to the Maryland Tax Court (a state-level administrative tribunal); from there to Circuit Court. Most appeals are resolved at Level 1 or Level 2. Comparable sales evidence is the most-effective basis for appeal.

About Frederick County

Beyond the property tax — a few things you might not know about the place.

Weird fact

Camp David (officially Naval Support Facility Thurmont, in the Catoctin Mountains of Frederick County) has hosted **every US President since Franklin D. Roosevelt** (who established it in 1942 as Shangri-La). The retreat covers approximately 200 acres of secured Maryland forest land and includes 11 cabins, an aspen grove, and a chapel. Famous Camp David events include: the 1959 Camp David Conference (Eisenhower-Khrushchev), the 1978 Camp David Accords (Begin-Sadat-Carter — the basis of the Egypt-Israel peace treaty), the 2000 Camp David Summit (Clinton-Barak-Arafat), and the G-8 summit (2012, hosted by Obama). The retreat's exact location is officially classified, though its general vicinity is well-known to locals.

Hometown hero

Francis Scott Key

The American lawyer and amateur poet (1779-1843) — author of The Star-Spangled Banner — was born in Frederick County (specifically at Terra Rubra Plantation, near Keymar). Key is buried in Mount Olivet Cemetery in downtown Frederick. The Francis Scott Key Memorial (in Mount Olivet Cemetery) features a substantial monument and the original burial site of both Key and his wife. Key wrote the lyrics to The Star-Spangled Banner during the September 13-14, 1814 Battle of Baltimore (Fort McHenry) but his Frederick County roots are well-preserved through the Key Family papers and historic Frederick sites.
