How Property Tax Works

Barrow County, Georgia operates on a property tax system that serves as the primary funding mechanism for essential local services including public education, county operations, emergency services, and infrastructure maintenance. Property taxes in Barrow County are assessed annually based on the fair market value of real estate as of January 1st each year. The Barrow County Board of Commissioners and Board of Education work together to set millage rates that determine your final tax obligation.

For the 2025 tax year, Barrow County property owners should expect a tentative increase of 3.30 percent in their property tax bills, pending final approval by the Board of Commissioners after required public hearings. Effective tax rates in Barrow County typically range from approximately 1.0% to 1.3% of assessed value, though actual rates vary significantly based on your specific location within the county due to different special taxing districts, municipal boundaries, and school district zones. Property owners in incorporated areas may face additional municipal taxes, while those in certain districts may be subject to special assessment districts for services like fire protection or water/sewer improvements.

Supplemental Tax Bills

Supplemental property taxes in Barrow County are additional tax assessments issued when property ownership changes hands, new construction is completed, or significant improvements are made to existing properties during the tax year. These supplemental bills represent the difference between the previous assessment and the new assessed value, prorated for the portion of the tax year remaining after the triggering event occurs.

Supplemental taxes are most commonly triggered by: new home purchases after January 1st, completion of new construction or major renovations, subdivision of land, or removal/addition of exemptions or credits. The supplemental tax is calculated by taking the difference between the old and new assessed values, multiplying by the current millage rate, and prorating based on the number of months remaining in the tax year.

Example: If you purchase a home in June that was previously assessed at $250,000 but now appraises at $400,000, you would owe supplemental tax on the $150,000 difference for the 7 months remaining in the tax year (June through December). At a 27-mill rate, this would equal approximately $2,835 in supplemental taxes ($150,000 × 0.027 × 7/12 months).

Escrow & Property Taxes

Most mortgage lenders in Barrow County require property tax escrow accounts for loans with less than 20% down payment, though many borrowers choose escrow even when not required. Your lender collects approximately 1/12th of your estimated annual property tax bill with each monthly mortgage payment, holding these funds in a separate escrow account. When your property taxes become due on December 15th, your lender pays the bill directly to Barrow County on your behalf.

Lenders are required to conduct annual escrow analyses, typically sent in late fall, which compare collected funds against actual tax bills. If property taxes increase significantly (as expected with the 3.30% tentative increase for 2025), you may face an escrow shortage requiring either a lump sum payment or increased monthly payments. Georgia law requires lenders to provide 60-day notice before increasing escrow payments due to tax increases.

Property owners with escrow accounts should verify that payments are made timely by checking the Barrow County Tax Commissioner's website or calling (770) 307-3000. If your lender fails to pay on time, you remain ultimately responsible for any penalties or interest charges, though you have legal recourse against the lender for their error.
