Georgia’s flat state income-tax rate falls to 4.99% for 2026, down from 5.19% the year before, under a law that took effect retroactively to January 1. Gov. Brian Kemp signed the measure in May, and it is a permanent rate reduction written into the tax code rather than a one-time rebate, with a schedule to keep stepping the rate down toward 3.99% in later years. For Georgia’s large population of retirees, the cut lands on top of one of the more generous retirement-income tax breaks in the country.
Georgia’s flat rate drops to 4.99% for 2026
Georgia moved from a graduated income tax to a single flat rate in 2024 and has been lowering that rate on a set path ever since. The 2025 rate was 5.19%; for tax year 2026 it is 4.99%, a reduction that applies to all taxable income at the same percentage. Because the change is retroactive to January 1, 2026, it covers the full tax year even though the bill became law months into it, as reflected in guidance from the Georgia Department of Revenue.
A flat rate makes the savings easy to size. Every $10,000 of taxable income that would have been taxed at last year’s rate is now taxed at 4.99%, trimming the bill by about $20 per $10,000 of income. For a retiree with taxable income in the tens of thousands after exemptions, the reduction is modest on its own but compounds with the exclusions Georgia already offers older filers.
The flat structure also means the cut reaches every filer proportionally rather than targeting a single bracket. Georgia no longer has graduated rates that phase a reduction in and out, so a retiree with a modest taxable income and a wealthier neighbor both see the same 4.99% applied. Both save the same fifth of a percentage point on each dollar taxed, which keeps the change simple to anticipate at filing time.

What HB 463 changed and when it took effect
The rate cut came through House Bill 463, which Gov. Kemp signed on May 11, 2026 as part of a broader tax package. The governor’s office framed the accelerated cut as a return of surplus revenue to taxpayers, and the law pairs the 2026 rate with additional changes phased in for 2027, including a higher standard deduction and an increase to the retirement-income exclusion.
The long-term design lowers the rate by further increments in later years, aiming toward 3.99%, though those future steps are tied to the state meeting revenue conditions. The 4.99% for 2026, by contrast, is locked in and retroactive, so it is not contingent on a later trigger. That distinction matters for planning: this year’s rate is settled, while the pace of future cuts depends on Georgia’s revenue picture in the years ahead.
The 2027 changes matter for planning even though they arrive later. Raising the standard deduction reduces the amount of income exposed to the rate, and lifting the retirement-income exclusion widens the shelter for older filers specifically. The full benefit of the package for retirees therefore builds across two tax years rather than landing all at once in 2026, so a household comparing its 2026 and 2027 returns should expect the larger drop in the second year.
How the cut stacks with Georgia’s retirement-income exclusion
The rate reduction is only part of the picture for older residents, because Georgia already shields a large share of retirement income from tax. Taxpayers 65 and older can exclude up to $65,000 of qualifying retirement income per person, and those 62 to 64 can exclude up to $35,000, covering pensions, withdrawals from retirement accounts, interest, dividends, and a limited amount of earned income, according to the state’s retirement-income exclusion rules.
Stacked together, the two provisions can leave many retired Georgians paying the 4.99% rate on only a slice of their income. A married couple both over 65 can exclude a substantial amount of retirement income before the flat rate applies at all, and Social Security benefits are already exempt from Georgia income tax entirely, which narrows the taxable base further.
How much a given household actually saves depends on how much of its income clears the exclusions in the first place. A retiree whose income is largely Social Security and excluded retirement income may owe little Georgia tax regardless of the rate, so the cut barely registers. One with substantial taxable investment income or wages outside the exclusion feels the 4.99% rate, and its reduction from last year, far more directly on the bottom line.
The headline is the rate, but the durable benefit for retirees is the combination. A permanent cut to 4.99%, retroactive across all of 2026, lowers the percentage owed, while the retirement-income exclusion shrinks the amount that percentage even touches. Whether the rate continues its march toward 3.99% depends on revenue the state has not yet collected, so the reliable assumption for now is the 4.99% that is already law rather than the lower figures still sitting on the schedule.
