Property tax 101

So what is property tax, anyway? Here are the basics:
  • Your local government uses property tax funds to pay for public works and community services, such as education and emergency services
  • “Real property” refers to property that cannot be moved, such as land, homes, and buildings, and for which the owner is charged property tax
  • Your property taxes are determined by a local tax assessor, who bases the decision on the local tax rate and market values
  • Taxes can change frequently given the constant flux in market conditions and local budgets
Essentially, property tax is a way for the local government to collect funds to redistribute through the community in the form of services and resources intended to benefit residents in some way.

How Gwinnett County property taxes are determined

Tax Assessors in your county determine your property’s value. All property in Georgia is assessed at 40% of its fair market value. This is the amount a knowledgable buyer would reasonably pay and a seller would willfully accept, assuming a legal sale. 
Assessors will also consider any income generated by a rental property and what it would cost to rebuild the property, less depreciation, plus land value.
Next, any exemptions are subtracted and millage rates are set. The millage rate is the tax rate used to determine local property tax. It is the amount per every $1,000 of a property’s assessed value that goes toward tax. 
The assessed value is then multiplied by the millage rate and any tax credits are subtracted. Then

If your payment is late, you will be charged 0.52% interest for each month a balance remains unpaid. After 120 days, an additional 5% penalty is added to the remaining balance. Another 5% penalty is added every subsequent 120 days to a maximum added penalty of 20%.
The owner as of January 1st of that year is responsible for the property taxes. A bill will be sent to the owner as of January 1st, as well as the new owner if the property was sold later in the year. 
If you sell your home, you can transfer the liability for property tax payment to the new owner. This is usually done as part of the property sale process. The same process stands if you wish to prorate the property taxes, as the tax commissioner does not prorate tax between the buyer and seller.
