Frederick County Property Tax at Lake Frederick

The Rate and How It Is Applied

Frederick County's TY2025 real estate tax rate is $0.480 per $100 of assessed value, confirmed in the Virginia Department of Taxation TY2025 Local Tax Rates publication. The Board of Supervisors sets the rate annually, typically in spring following the reassessment cycle. Frederick County operates on an annual reassessment schedule — meaning assessed values are updated every year rather than on the four-year or six-year cycles that some Virginia counties use. The county is required by Virginia law to assess at 100% of fair market value, and with annual cycles, Lake Frederick home values track the actual market more closely than in counties with longer reassessment gaps.

The practical consequence of annual reassessment showed up sharply in 2025. Frederick County's average assessed value increased approximately 20% in the 2025 cycle, reflecting the appreciation that the Shenandoah Valley real estate market — including the Lake Frederick community — experienced during 2023 and 2024. A home assessed at $500,000 in 2024 became $600,000 in 2025 at that rate of increase. At $0.480 per $100, the tax bill on that home went from $2,400 to $2,880 — an increase of $480 per year, or $40 per month. The Board of Supervisors discussed a revenue-neutral rate reduction that would have offset some of the value increase, but the rate ultimately held at $0.480, meaning most homeowners saw real increases in their tax bills despite the rate remaining constant.

Taxes are billed in two installments due June 5 and December 5. A bill received in May covers the first half of the tax year; the December bill covers the second half. Payments can be made online through the Frederick County tax portal, by mail, or in person at the Commissioner of Revenue office. Late payments accrue interest and penalties — confirm current penalty rates with Frederick County.

Tax Math at Lake Frederick Price Points

Trilogy — New Construction and Resale

On a $490,000 Trilogy entry-level home assessed at full purchase price: Frederick County at $0.480 produces $2,352 per year, or $196 per month. On a $600,000 Trilogy home: $2,880 per year, $240 per month. On a $700,000 Trilogy home: $3,360 per year, $280 per month. On an $800,000 upper-tier Trilogy home: $3,840 per year, $320 per month. On a $900,000 large-lot custom Trilogy home: $4,320 per year, $360 per month.

These figures assume assessed value equals purchase price, which Virginia law requires. In practice, if a home was purchased several years ago at a lower price and has not been reassessed to current market value, the actual tax bill may be lower than the current-purchase-price calculation. However, with annual reassessment cycles, the lag between purchase price and assessed value is shorter at Lake Frederick than in counties that reassess every four to six years — expect the assessed value to track within one cycle of market value.

Ryan Homes Section

On a $380,000 Ryan section townhouse: $1,824 per year, $152 per month. On a $450,000 Ryan section single-family: $2,160 per year, $180 per month. On a $520,000 Ryan section home: $2,496 per year, $208 per month. The Ryan section's lower price points produce proportionally lower tax bills — one of the financial arguments for the Ryan section over Trilogy for buyers who want the Lake Frederick location but are more sensitive to total monthly carrying cost.

The Northern Virginia Comparison

The majority of Trilogy buyers at Lake Frederick come from Northern Virginia — Loudoun, Fairfax, Prince William, Arlington, Alexandria, and the Maryland suburban corridor. For those buyers, Frederick County's $0.480 rate represents a fundamental change in the tax relationship between the government and their home.

Loudoun County's TY2025 real estate rate is $1.04 per $100. On a $700,000 home in Loudoun, the annual real estate tax is $7,280. The same home in Frederick County produces $3,360 — a difference of $3,920 per year. On an $800,000 home: Loudoun charges $8,320, Frederick County charges $3,840, a savings of $4,480 per year. Fairfax County at $1.035 and Arlington at $1.013 produce similar disparities. Prince William County at $0.9950 is lower than those but still more than double Frederick County's rate. Over a 20-year retirement at consistent values, the tax savings from moving to Frederick County rather than staying in Loudoun on an $800,000 home exceeds $89,000. In a rising market where both counties appreciate similarly, that proportional savings accumulates faster.

For buyers relocating from further afield — Maryland, DC, Pennsylvania — the comparison depends on their origin jurisdiction's rate. Montgomery County, Maryland charges roughly $1.10 per $100 equivalent. DC's property tax structure for residential property runs in the $0.85 range for the first tier. Frederick County's $0.480 is competitive against essentially every high-cost Mid-Atlantic jurisdiction from which Lake Frederick draws buyers.

Annual Reassessment: Implications for Long-Term Owners

Annual reassessment is a double-edged feature. On the way up — as the Shenandoah Valley market appreciated through 2022 to 2025 — annual reassessment meant tax bills increased each year to reflect rising values, faster than they would have under a four-year cycle. A buyer who purchased a Trilogy home in 2021 at $480,000 may have seen the assessed value climb to $580,000 by 2024 and $680,000 by 2025, with tax bills rising proportionally. There is no multi-year lag between what the market says the home is worth and what the county taxes it at.

On the way down — if the market corrects — annual reassessment works in the homeowner's favor. Values and tax bills decline within one cycle rather than taking several years to catch up. Buyers who purchased near a market peak get relief within 12 months of a correction rather than paying inflated assessed value taxes for years while the market has already moved lower. The annual cycle is neither inherently good nor bad for the homeowner — it is simply more responsive in both directions.

Property owners who believe their assessment exceeds fair market value have the right to appeal. The appeal process begins with the Frederick County Commissioner of Revenue, which reviews comparables and will adjust an assessment that is demonstrably above market. If the Commissioner's office does not resolve the dispute, the Board of Equalization — an independent three-member panel — hears formal appeals. The deadline for appeal is typically 30 days from the date on the assessment notice. Engage a Virginia-licensed appraiser if you plan to appeal; a recent appraisal showing lower market value is the strongest evidence in the process.

Tax Relief Programs

Frederick County offers real estate tax relief for qualifying senior citizens and individuals with permanent disabilities. To qualify, applicants must be at least 65 years of age or permanently disabled, must occupy the property as their primary residence, and must meet income and net worth thresholds set by the county. The income and asset thresholds are adjusted periodically — contact the Commissioner of Revenue at fcva.us or by calling the Frederick County government for current eligibility limits. The program can provide partial or full real estate tax relief depending on income level relative to the threshold.

Virginia veterans with a 100% permanent and total service-connected disability qualify for a complete exemption from real estate tax on their primary residence under Virginia Constitution Article X, Section 6-A and Virginia Code Section 58.1-3219.5. Frederick County participates in this state-mandated program. The surviving spouse of a veteran who died in the line of duty while on active duty also qualifies for the full exemption. Veterans who believe they qualify should contact the Commissioner of Revenue office to begin the application process, which requires documentation of the service-connected disability rating from the Department of Veterans Affairs.

For the substantial retired military community at Lake Frederick — the community draws buyers from Quantico, Fort Belvoir, Dahlgren, and Fort Hill, all within an hour — the veteran exemption can eliminate the real estate tax entirely on a $600,000 Trilogy home, saving $2,880 per year indefinitely. That is a material financial benefit that many veterans do not realize is available and never apply for.
