About Property Taxes in Union County, Georgia
Union County's taxes rank among America's lowest
Union County's 0.505% effective rate is among Georgia's absolute lowest, making it exceptionally tax-friendly compared to any national benchmark. The median property tax of $1,376 is just 51% of the national median of $2,690, despite Union's elevated median home value of $272,600 rivaling affluent national communities. This ultra-low rate places Union in the lowest-tax percentile nationally—a rare combination of high home values and minimal tax burden.
Union ranks as one of Georgia's most tax-friendly
At 0.505%, Union County ranks in Georgia's bottom 5% by effective tax rate—one of just a handful of the state's 159 counties offering such exceptional affordability. Union dramatically undercuts the state average of 0.898%, creating a tax burden roughly 40% lower than the typical Georgia county. This places Union among Georgia's premier destinations for tax-conscious homeowners and retirees seeking maximum tax relief.
Union dramatically undercuts all regional rivals
Union's 0.505% rate is less than half every neighboring county's rate, dramatically undercutting Towns (0.365%), Tift (0.936%), and all South Georgia peers. Union's mountainous North Georgia location attracts affluent buyers seeking scenic mountain living, yet the county maintains exceptionally modest tax rates reflecting its rural service model. This creates a powerful draw for wealthy retirees and remote-work professionals building second homes in mountain communities.
What you'll pay on a typical Union home
The median Union County home valued at $272,600 generates just $1,376 in annual property tax—roughly $115 per month, exceptional for a property worth a quarter-million dollars. With mortgage deductions, taxes rise modestly to $1,426 annually, still among the nation's lowest for this price point. This remarkable tax-to-value ratio explains Union's appeal to affluent homebuyers and retirees seeking mountain communities with minimal tax exposure.
Review your assessment if purchase price differs significantly
Even in tax-friendly Union County, recent home purchases sometimes show assessments that don't reflect the actual sale price paid, creating overpayment opportunities. Homeowners can file a reassessment appeal within 45 days of their notice, providing the deed or purchase documentation as evidence of true value. In Union's active mountain real estate market, recent sales data is abundant and appeals often succeed in achieving fair assessments.
Tax Rate Details
Understanding Millage Rates in Union County
In Georgia, property taxes are expressed as a millage rate (also called a mill rate). One mill equals $1 of tax for every $1,000 of assessed property value. Your total property tax bill is determined by adding together the millage rates set by the county, city or municipality, school district, and any special districts.
In Georgia, property is assessed at 40% of fair market value. The millage rate is applied to this assessed value, so a home worth $300,000 has an assessed value of $120,000 for tax purposes. Georgia counties, cities, and school districts each set their own millage rates.
Union County has an effective property tax rate of 0.50%, resulting in a median annual tax bill of $1,376. Use the calculator above to estimate your property tax based on Union County's current rate, or contact the Union County tax assessor's office for the exact millage rate breakdown for your property.
