Every Rockdale levy from the GA DOR 2025 digest: Conyers and unincorporated. High mills, real money — exemptions are not optional reading.
Tax on a $350,000 home in unincorporated Rockdale County. That’s about $447 a month in escrow. Georgia assesses 40% of market value ($140,000 here), and this scenario’s 2025 levies total 38.282 mills.
Homestead exemptions reduce this — see the exemptions section below. Confirm any parcel with the county tax assessor / commissioner.
Rockdale County property tax, explained
Georgia doesn’t tax your full home value. It taxes 40% of fair market value (O.C.G.A. § 48-5-7) — the assessed value. Every levy on your parcel then charges its millage against that number: $1 per mill per $1,000 of assessed value.
On a $350,000 home that’s $140,000 assessed, so every mill costs $140 a year. Keep that number in your head — it’s how you compare any two addresses in this county in about five seconds.

Rockdale County homestead exemptions

- Regular homestead + HOST: file with the Board of Assessors by April 1. HOST amount is set annually by the BOC — confirm current dollars with Assessors (770-278-7676); not invented here.
- HB 581: Rockdale County and schools stayed in for 2025 per available summaries.
- Due date: November 15.
- Apply: Board of Assessors, 958 Milstead Ave Suite 101, Conyers. Bring ID, deed, utility proof.
Buying a resale? Don’t budget off the seller’s bill.
A seller with a long-time freeze, senior exemption or HOST credit can show a bill that looks nothing like yours. Pull the current assessed value, run today’s millage, and set escrow on your number. Or send me the address — I’ll do it.
