Loudoun's Board of Supervisors adopted the FY2027 budget on April 7, 2026, holding the real property tax rate at $0.805 per $100 of assessed value for tax year 2026, so an $800,000 assessment pays about $6,440 a year. The trend matters more: the board has lowered the rate nearly every year for a decade, from $1.145 in 2016 to $0.805 today, helped by the world's largest concentration of data centers diversifying the tax base (loudoun.gov). Compare Cook County: a 2.02% median effective rate on the $293,700 median home value works out to about $5,941 a year, and median residential bills jumped more than 16% in 2025 with no cap on annual assessment increases (Ownwell). In Loudoun the average bill rose only about $141 in 2026, and the vehicle tax cut more than offsets it for most owners.

Illinois taxes every dollar at a flat 4.95%, locked in the state constitution after voters rejected a graduated-tax amendment in 2020. Virginia uses four graduated brackets: 2% up to $3,000, 3% to $5,000, 5% to $17,000, and 5.75% above $17,000 (Tax Foundation, 2026). For a typical household the effective bills land close: a 2026 analysis put Virginia's effective state tax rate at 4.5% and Illinois' at 4.7% (USA Today via Reuters). Virginia's edge shows at the bottom, where the first dollars are taxed at 2% and 3% instead of 4.95%, and Loudoun adds no local income tax. Do not move expecting an income-tax windfall, but the property and sales tax savings do the real work.

Sources and Next Step
Chicago's combined sales tax is 10.25%, ranking among the highest of any major US city (TaxJar, February 2026; Civic Federation FY2026 report). A pending transit increase could lift it to 10.50%. In Northern Virginia the combined rate is 6%: Virginia's 5.3% state rate plus the 0.7% regional transportation add-on. Every restaurant check, furniture delivery, and car repair costs more than four points less in tax. Illinois eliminated its 1% statewide grocery tax on January 1, 2026, but many municipalities kept a local 1% grocery tax, so the register rarely feels different.

Loudoun's August 2026 numbers: $818,000 median sale price, up 1% year over year, 17 days on market, 99.9% sold-to-list, 836 active listings (Bright MLS via colganteam.com). Homes sell in barely two weeks at essentially full asking, so a relocator buying in Ashburn or Leesburg steps into demand that absorbs listings fast and equity that compounds from day one. Cook County's median home value sits near $293,700. Newer construction across Brambleton, One Loudoun, and the Route 7 corridor adds a quieter win: fewer surprise capital expenses than Chicago's older stock, where roofs, boilers, and tuckpointing bills never show up in a mortgage calculator.

Growth here funds itself. The data centers that pushed the property tax rate down supply the commercial revenue behind Loudoun's $5.4 billion FY2027 budget, which funds a $2.1 billion school operating budget, up $105 million (loudoun.gov, April 7, 2026). The Silver Line's Ashburn station puts downtown DC within a one-seat Metro ride, and Dulles International sits 15 to 20 minutes from most Loudoun neighborhoods, which matters when the Chicago move keeps you flying back for holidays.
