How Property Tax Works

Miller County, Georgia operates on a property tax system that funds essential local services including schools, public safety, infrastructure, and county operations. Property taxes are assessed annually based on fair market value, with the Miller County Tax Commissioner responsible for billing and collecting taxes on behalf of various taxing authorities including the county, school district, and any applicable special districts.

The effective tax rate in Miller County varies by location within the county due to different combinations of taxing districts that may apply to individual properties. Property owners should expect their actual tax rate to differ based on their specific location and the special taxing districts that serve their area. Georgia's property tax system allows for various tax credits that can reduce your tax bill, though most require annual application and are not automatically applied.

Supplemental Tax Bills

Supplemental taxes in Miller County are additional property tax assessments that occur when there are changes to a property during the tax year. Common triggers include new construction, additions or improvements to existing structures, changes in property ownership, or corrections to the assessment roll.

When supplemental taxes are levied, they are calculated on a pro-rated basis from the date the change occurred through the end of the current tax year. For example, if a homeowner completes a $50,000 addition in June, they would receive a supplemental tax bill covering the increased assessment from June through December. The Miller County Tax Commissioner handles the billing and collection of supplemental taxes using the same process as regular property taxes.

Escrow & Property Taxes

Most mortgage lenders in Miller County require borrowers to maintain an escrow account for property tax payments. The lender collects monthly escrow payments along with your mortgage payment and pays your property taxes directly to the Miller County Tax Commissioner when they become due.

Property taxes in Miller County are due from March 1st through October 15th each year. Lenders typically pay the taxes early in this window to avoid any late payment penalties. Property owners should verify that their lender has made the payment by checking with the Miller County Tax Commissioner's office or reviewing their annual escrow analysis statement. If you pay your own property taxes, remember that penalties apply to taxes not paid by October 15th.
