How Property Tax Works

Hart County, Georgia operates on a property tax system that serves as the primary funding source for essential county services, including public safety, road maintenance, parks and recreation, and administrative services. The county also collects property taxes on behalf of the Hart County Board of Education and various state programs. Property taxes in Hart County are based on assessed values determined by the Hart County Board of Tax Assessors, with tax bills calculated using millage rates set annually by the Board of Commissioners.

For the current tax year, Hart County has a millage rate of 13.156 mills, representing an increase of 0.401 mills over the rollback rate of 12.755 mills. This translates to approximately $13.156 per $1,000 of assessed value. However, your actual tax rate may vary depending on your specific location within the county, as special taxing districts and municipal boundaries can affect the total millage rate applied to your property. The county handles billing and collection of its own property taxes while also collecting taxes for the school district and state.

Section 4

Supplemental Tax Bills

Supplemental taxes in Hart County are additional property tax assessments that occur when there are changes in property ownership, new construction, or improvements made to existing properties during the tax year. These taxes are calculated based on the difference between the previous assessed value and the new assessed value, prorated for the portion of the tax year remaining after the change.

For example, if you purchase a home in Hart County in July and the assessed value increases from $250,000 to $350,000, you would receive a supplemental tax bill for the additional $100,000 in assessed value, calculated at the current millage rate and prorated for six months (July through December). With Hart County's current rate of 13.156 mills, this would result in approximately $658 in additional taxes ($100,000 × 0.013156 ÷ 2). Supplemental tax bills are issued separately from regular annual tax bills and have their own payment due dates.

Escrow & Property Taxes

Most mortgage lenders in Hart County require borrowers to maintain an escrow account for property tax payments, especially for loans with less than 20% down payment. Your lender will estimate your annual property tax liability and divide it by 12 to determine your monthly escrow payment. This amount is collected along with your mortgage payment and held in a separate account until tax payments are due.

Hart County typically issues property tax bills in the fall, with payment deadlines around December 20th (though specific dates may vary by year). Your lender will receive the tax bill directly and make payment from your escrow account. Lenders are required to provide annual escrow statements showing all deposits and payments made on your behalf. If your property taxes increase due to reassessment or rate changes, your lender may adjust your monthly escrow payment and could require you to make up any shortage over 12 months. You can verify that your taxes have been paid by checking with the Hart County Tax Commissioner's office or through their online payment system.

Frequently Asked Questions

Q: When are property taxes due in Hart County? A: Property tax bills are typically due by December 20th each year, though the exact date may vary. Property tax returns must be filed between January 1 and April 1 annually.

Q: What homestead credit is available and how do I apply? A: Hart County offers homestead credits that help limit assessment increases on your primary residence. Beginning January 1, 2025, a new statewide homestead credit becomes available. Applications must be filed with the Hart County Tax Assessor's office by January 1st to receive the credit for the current tax year. This credit is NOT automatic and requires application.

Q: How does the homestead credit work? A: The homestead credit caps the annual increase in your home's assessed value, typically limiting growth to a certain percentage each year. It does not reduce your home's market value but protects you from dramatic assessment increases. You must own and occupy the property as your primary residence on January 1st and file the application by the same date.

Q: How often are properties reassessed in Hart County? A: Georgia law requires properties to be assessed annually, but Hart County may conduct comprehensive reappraisals on a cyclical basis. Contact the Hart County Board of Tax Assessors for specific information about assessment schedules and appeal procedures.

Q: What happens if I pay my taxes late? A: Late property tax payments in Hart County incur penalties and interest charges. Contact the Hart County Tax Commissioner's office for specific penalty rates and payment options if you're unable to pay by the due date.

Q: Can I pay my property taxes online? A: Many Georgia counties offer online payment options for property taxes. Contact the Hart County Tax Commissioner's office or visit their website to determine available online payment methods and any associated convenience fees.

Q: Why might my tax rate be different from my neighbor's? A: Tax rates can vary within Hart County based on special taxing districts, municipal boundaries, school district zones, and other local assessments. Your total millage rate depends on your property's specific location and applicable taxing jurisdictions.

Q: What other tax credits might be available? A: Hart County may offer additional tax credits for seniors, disabled veterans, or other qualifying circumstances. Contact the Hart County Board of Tax Assessors to learn about available programs, eligibility requirements, and application procedures. All credits require separate applications and are not automatically applied.
