Georgia’s Flat Income Tax Rate on CD Interest
Georgia moved from a progressive income tax to a flat rate beginning in 2024, and the legislature has cut the flat rate further each year since. Under HB 463, the flat rate for 2026 is 4.99% for all residents, regardless of income — down from 5.19% in 2025.
After-tax yield on a 4.35% CD for a GA resident (22% federal + 4.99% GA):
- Total marginal rate: ~26.99%
- After-tax yield: ~3.18%
Georgia’s rate has been on a declining path (confirm the current-year rate at dor.georgia.gov, since further cuts are conditional on state revenue triggers):
- 2025: 5.19%
- 2026: 4.99%
- Future years: additional 0.125-point cuts toward a 3.99% target, if revenue conditions are met
T-Bills vs. CDs for Georgia Residents
Treasury bill interest is exempt from Georgia state income tax.
| 12-Month CD (top rate) | 1-Year Treasury | |
|---|---|---|
| Gross yield | ~4.35% | ~4.37% (per Fed H.15, Sept 14, 2026) |
| Federal taxable | Yes | Yes |
| GA state taxable (4.99%) | Yes | No |
| After-tax yield (22% federal + 4.99% GA) | ~3.18% | ~3.41% (federal-only) |
For Georgia residents in 2026, the Treasury’s state tax exemption gives it a modest after-tax edge over the CD at these rate levels. Recalculate using the live 1-year Treasury yield at each reinvestment decision, since it moves daily.
