Columbia County, Georgia property owners pay a combined millage rate of about 25.70 mills in unincorporated areas and 27.94 mills inside city limits like Grovetown and Harlem, applied to 40% of a property’s fair market value. On the sales side, most retail purchases carry an 8% combined rate. Those two numbers drive almost every tax question people ask about Columbia County, so the sections below show what makes them up, how they translate into a bill, and the exemptions and deadlines that change what you actually owe.
What Makes Up the Property Tax Millage Rate
One mill equals one dollar of tax for every $1,000 of assessed value.1Georgia Department of Revenue. Property Tax Millage Rates The unincorporated rate in Columbia County is built from four separate levies, each set by a different authority:2Columbia County, GA.

- County bond: 1.207 mills
- Fire district: 2.241 mills
- School operations: 18.30 mills

How Your Property Tax Bill Is Calculated
Georgia assesses property at 40% of fair market value, not the full amount.3Justia. Georgia Code 48-5-7 – Assessment of Tangible Property The Columbia County Board of Tax Assessors determines fair market value for every parcel.4Columbia County, GA. Tax Assessor
Take a home with a fair market value of $350,000 in an unincorporated area:
- Assessed value: $350,000 × 40% = $140,000
- Gross tax before exemptions: $140,000 × 25.6967 mills ≈ $3,598
- Final tax: subtract any homestead exemption from the assessed value, then multiply by the millage rate
Each spring, the county mails a Notice of Assessment showing the appraiser’s fair market value and an estimated tax using the prior year’s millage. If you think the value is wrong, you have 45 days from the date on that notice to file a written appeal with the Board of Tax Assessors.5Justia. Georgia Code 48-5-311 – Creation of County Boards of Equalization
Homestead Exemptions That Lower the Bill
Homestead exemptions cut the assessed value before the millage rate is applied, so they reduce your bill dollar-for-dollar. You must own and occupy the property as your primary residence on January 1, and the application deadline is April 1 at the Columbia County Property Tax Office at 630 Ronald Reagan Drive in Evans.6Columbia County, GA. Tax Exemptions Bring a Georgia driver’s license showing the property address, proof of county motor vehicle registration, and a copy of your recorded warranty deed. Once approved, it renews automatically each year.
Standard State Exemption (S1)
The basic statewide homestead exemption removes $2,000 from your assessed value.
Columbia County Local Exemption
Columbia County adds a local exemption of $8,000 off assessed value for county tax purposes, stacked on top of the S1. A qualifying homeowner reduces taxable assessed value by $10,000 before county millage is applied.
Disabled Veteran Exemption
Veterans with a service-connected disability may qualify for an exemption of up to $121,812 off assessed value, indexed annually by the U.S. Secretary of Veterans Affairs.7Georgia Department of Veterans Service. Disabled Veteran Homestead Tax Exemption For a veteran with a 100% rating, this can wipe out property taxes on a modest home. Submit the VA disability rating documentation with the application.
Sales Tax and the Vehicle TAVT
Most retail purchases in Columbia County carry an 8% combined sales tax: 4% state and 4% local, with the local portion including a Special Purpose Local Option Sales Tax (SPLOST) that funds capital projects. Addresses near the Richmond County (Augusta) border can fall in jurisdictions with rates as high as 8.5% or 9%.
Groceries bought for home consumption are exempt from the state 4% portion, though local sales tax still applies. Prescription drugs are fully exempt.
Vehicles work differently. Georgia replaced sales tax and the old annual vehicle ad valorem tax with a one-time Title Ad Valorem Tax (TAVT), currently 7.0% of fair market value, paid when you title the vehicle.8Georgia Department of Revenue. Vehicle Taxes – Title Ad Valorem Tax (TAVT) and Annual Ad Valorem Tax On a $35,000 car, that is $2,450 at the tag office. There is no recurring vehicle property tax after that initial payment, though annual registration taxes are due each year on the owner’s birthday.
Agricultural and Timber Land
Owners of farm or timber land can apply for Conservation Use Valuation Assessment (CUVA), which assesses qualifying property at 40% of its current use value rather than its fair market value. For land that might otherwise be valued as potential residential development, the difference can be large.9Department of Revenue. Conservation Use Land Values
CUVA locks you into a ten-year covenant. Breaking it early triggers repayment of the tax savings plus interest. Parcels under ten acres face extra scrutiny to prove bona fide agricultural use, and no single owner can claim CUVA on more than 2,000 acres statewide. Applications go to the Columbia County Board of Tax Assessors by the county’s ad valorem tax return deadline.
