Heads up, property-owning Gwinnettians: Your tax bills are in the mail.

Gwinnett tax commissioner Richard Steele announced Wednesday that 2018's property tax bills were headed toward home- and business owners. Those who signed up for paperless billing will receive bills via email, and they are also available online at GwinnettTaxCommissioner.com for immediate viewing.

The county's Board of Commissioners adopted this year's millage rate — a "rollback" rate of 13.319 mills — in June. The county's Board of Education adopted a separate millage rate of 21.75 mills.

One mill equals $1 in property taxes for every $1,000 in assessed value.

Tax bill payment is due by Oct. 15.

Residents and business owners can pay online on the tax commissioner’s website (either by check or debit card); via mail to P.O. Box 372, Lawrenceville, Ga., 30046; in person at any location of the tax commissioner’s office; and via drop box at any county tag office.

Those with questions can email tax@gwinnettcounty.com or call 770-822-8800.
