Walton County Property Tax: 2026 Guide Walton County property tax bills hit differently in 2026. After the Board of Commissioners voted 4-3 to raise the county millage rate by nearly 20% — from 10.413 to 12.278 mills — residents packed the streets of downtown Monroe in protest.

For homeowners in one of metro Atlanta's fastest-growing counties (3.53% annual growth rate), the median tax bill now sits at $2,431 per year, and many are seeing assessed values climb alongside the rate increase.
