The new TAVT tax is a one time only tax. After paying the tax all that you have to pay is the yearly tag fee of $20.00
When purchasing a new vehicle the tax is calculated and added to the cost of the vehicle. They do not add sales tax any longer to new purchases. Once the tax is paid on the tag fee is due each year on your birthday.
For new residents of Georgia that are registering vehicles. The tax is figured on the value of the vehicle (not what you paid for it) and multiplied by 7%. This value is your tax, 50% is due at the time of registering the vehicle and the remaining 50% is due within 12 months. After that only the tag fee is due each year.
I purchased my car before the TAVT tax went into effect so I pay a yearly tag tax that is the value times the millage rate set by my county.
The TAVT does not cover pull behind trailers, boats or campers so those would fall under the yearly tax bill of value X millage rate.
