How Property Tax Works

Marion County, Georgia operates under the state's property tax system to fund essential local services including education, public safety, infrastructure, and county operations. For the 2025 tax year, Marion County maintains a property tax rate of 6.14 mills (0.614%), which has remained stable from previous years. Property owners can expect their effective tax rate to vary based on their specific location within the county and applicable special taxing districts.

The county assesses all real and personal property at fair market value, with tax calculations based on the assessed value multiplied by the applicable mill rate. Property tax revenue is critical for maintaining county services, with Marion County expecting to collect significant property tax revenue to support local operations. Actual tax rates may vary by location within Marion County due to special taxing districts, municipal boundaries, and school district variations, so property owners should verify their specific rate based on their property's exact location.

Section 4

Supplemental Tax Bills

Supplemental taxes in Marion County are additional property tax assessments that occur when there are changes in property ownership, value, or use outside of the regular assessment cycle. Common triggers include new construction, property improvements, ownership transfers, or changes in property classification. When a supplemental assessment is issued, it covers the period from when the change occurred through the end of the current tax year.

For example, if you complete a $50,000 home addition in July, the county assessor will issue a supplemental tax bill for the increased assessed value from July through the remainder of the tax year. The supplemental tax would be calculated as: ($50,000 increase × applicable mill rate × months remaining in tax year ÷ 12 months). Property owners typically receive supplemental tax bills within 30-90 days of the triggering event and must pay them separately from regular property tax installments.

Section 5

Escrow & Property Taxes

Most mortgage lenders in Marion County require property tax escrow accounts for borrowers with less than 20% down payment. Your lender collects monthly property tax payments along with your mortgage payment, depositing these funds into an escrow account. The lender then pays your property taxes directly to Marion County when bills are due, typically by the April 1st deadline.

Lenders analyze your escrow account annually and may adjust monthly payments based on actual tax bills and account balances. If your property taxes increase due to reassessment or rate changes, expect your monthly escrow payment to increase accordingly. Property owners should review their annual escrow analysis statements carefully and contact their lender if they notice discrepancies. For properties without escrow accounts, owners are responsible for making direct payments to Marion County by the established due dates to avoid penalties and interest charges.
