Two buyers open the same search this month. One is looking at a rowhouse in Old Town Fairfax. The other is looking at a similar-sized colonial out toward Fair Oaks. Both listings say "Fairfax, VA." Both buyers will tell friends they're moving to Fairfax. And this year, for the first time in over a decade, the buyer closer to downtown may end up with the higher tax bill, not because the house is worth more, but because the government sending that bill just absorbed a cost it never got to negotiate.
The word "Fairfax" covers two separate governments with two separate tax rates, two separate police departments, and two separate budget processes. Most of the region's real estate content treats this as trivia. It isn't. The gap between what those two governments charge just moved in a direction that upends the assumption most buyers walk in with, and the reason why is worth understanding before anyone signs a contract.
Two Governments, One Name
The City of Fairfax is an independent city under Virginia law, legally and administratively separate from the county that surrounds it, with its own council, its own police department, and roughly 24,000 residents packed into a compact footprint near George Mason University. Fairfax County is a different animal entirely: close to 1.16 million residents spread across McLean, Great Falls, Vienna, Oakton, Tysons, Reston, Burke, Centreville, Fairfax Station, and dozens of other communities. When someone says "I live in Fairfax," they almost always mean the county. The independent city is a small, self-governing island inside it.
That distinction usually shows up as a footnote. This year it shows up on a tax bill.
The Rate That Moved
For years, the City of Fairfax carried a lower real estate tax rate than the county around it, which fit the general assumption that a small, tightly-run city government costs less to fund than a sprawling county bureaucracy. Heading into fiscal year 2026, the city's rate sat at $1.03 per $100 of assessed value.
Then the city's own budget math stopped cooperating. City Manager Bryan Foster's February 2025 proposal recommended raising the rate to $1.125, a jump he said was necessary mainly to cover rising school costs. The city council went further. In March 2025, the council voted 4-2 to adopt an advertised rate of $1.150 per $100 of assessed value, a full $0.12 increase over the prior year. On a typical single-family home assessed near $798,300, the higher adopted rate means a larger annual bill.
Fairfax County's adopted rate for the same fiscal year landed at $1.1225 per $100 of assessed value, set by the Board of Supervisors and posted on the county's real estate tax rate page. Run that same $798,300 assessed value through the county's rate instead of the city's, and the bill comes out to roughly $8,962, below the bill at the city's adopted rate. A gap that used to run in the city's favor by a wide margin has effectively closed.
| City of Fairfax | Fairfax County | |
|---|---|---|
| Population | ~24,000 | ~1.16 million |
| FY2026 real estate tax rate | $1.150 per $100 | $1.1225 per $100 |
| City's prior-year rate, for reference | $1.030 per $100 | — |
| Median sale price, most recently reported month | $710,000 (March 2026) | $813,000 (3 months ending May 2026) |
A single line item did most of that work.
Where the Extra Twelve Cents Actually Went
The City of Fairfax doesn't run its own school district in the way most people assume an independent city would. It owns four school buildings, Daniels Run Elementary, Providence Elementary, Katherine Johnson Middle School, and Fairfax High School, but Fairfax County Public Schools operates them under a School Services Agreement first signed in 1962 and revised in 1978. FCPS hires the staff, sets the curriculum, and runs day-to-day operations. The city's role is governance, capital upkeep on the buildings, and paying an annual tuition bill calculated from the FCPS operating budget.
That bill has been climbing steadily for years: $53.4 million for roughly 2,884 city students in FY2023, $55 million for FY2024, $58.8 million for about 2,734 students in FY2025. Then it jumped to $71.4 million for a projected 2,992 students in FY2026, a $12.6 million increase in a single year. Patch reported that School Board Chair Carolyn Pitches called the adjustment "atypical" compared to a decade of swings that usually ran closer to $1.5 million a year.
Part of that jump came from enrollment growth. Most of it came from FCPS's own operating budget, which grew by roughly $300 million system-wide, and from the city's share of that total climbing from 1.54 percent to 1.64 percent under the contract formula. The City School Board appoints citizen representatives to FCPS advisory committees, but the city has no independent vote over how large the countywide operating budget grows. It simply owes its contractual share once that number is set.
As FFXnow reported, Foster told the council the city needed "the funding sources available in order to balance the budget."
Leaving the agreement isn't a realistic escape valve either. Under its terms, a decision to exit wouldn't take effect for three years, during which the city would keep paying tuition while simultaneously hiring teachers and administrators, buying buses, and building an entire school division from nothing, according to city budget presentations covering the School Services Agreement. The contract has run since 1962 for a reason: there's no cheaper alternative on the table.
Why the Median Price Doesn't Settle the Comparison
The City of Fairfax's median sale price ran $710,000 in March 2026, well below the county's $813,000 median over the three months ending May 2026. On the surface, that still reads as the city winning on affordability even after the tax increase. It might, but the comparison is shakier than it looks, because the two numbers come from markets of very different sizes.
Only 31 homes sold citywide in March 2026. The county, over its three-month window ending in May, saw 1,500 homes sell in May alone. A median built on 31 transactions moves a lot when a handful of unusually priced homes close in the same month, while a median built on 1,500 transactions barely notices the same swing. That's not a knock on the city's market, it's just a reminder that a City of Fairfax median from any single month deserves more scrutiny than a county median from the same window, since fewer sales are doing more work to produce the number.
What to Check Before You Write an Offer
None of this means the city is a bad place to buy. It means "Fairfax" isn't a single financial fact, it's two of them, and the gap between those two facts just moved.
Before writing an offer on anything listed as Fairfax, confirm a few specifics:
- Which jurisdiction actually taxes the parcel. A Fairfax, VA mailing address can sit in either the independent city or the county, and only the tax bill or a parcel lookup settles it.
- The current adopted rate for that specific jurisdiction, not last year's rate and not the rate quoted in an older article. The city's rate moved twelve cents in one budget cycle.
- Whether the property falls in one of the four school buildings under the City's tuition contract, since those attendance boundaries carry a cost structure the city doesn't control.
- How many sales actually underlie any median price being quoted, especially for the city, where a handful of closings can swing the number.
FAQ
Is the City of Fairfax part of Fairfax County? Geographically it sits inside the county's boundaries, but legally it's an independent city with its own government, police department, and tax rate, separate from the county administration.
Do City of Fairfax students attend Fairfax County Public Schools? Yes. Under the School Services Agreement, FCPS operates the four city-owned schools, and the city pays FCPS an annual tuition contract to cover that arrangement.
Will the city's tax rate keep climbing at this pace? There's no way to guarantee a future rate, but the FY2026 increase was driven specifically by an unusually large jump in the FCPS tuition bill. Whether future years see similar jumps depends on FCPS's own budget growth, which the city doesn't set.
Numbers like these are exactly why "median price" isn't the whole story in a market split across two governments. If you're comparing a home in Old Town Fairfax against one in Fair Oaks or Vienna, run the actual jurisdiction, the actual current rate, and the actual school contract before you get attached to a number a portal handed you.
