Georgia Bonus Depreciation: State Add-Back, Federal Benefit Intact.
Georgia does not adopt federal §168(k) bonus depreciation. An individual Georgia investor still claims the full federal Year-1 bonus, but for Georgia income tax the federal bonus is added back and the reclassified basis is recovered over the asset's normal 5, 7, and 15-year lives rather than expensed in Year 1. That is a timing difference, not a lost deduction, and current-year federal usability still depends on passive-activity, at-risk, basis, and business-interest limits.

The 30-second answer: Georgia does not adopt federal §168(k) bonus depreciation (O.C.G.A. §48-1-2). An individual still claims the full federal Year-1 bonus on the federal return, but for Georgia income tax the federal bonus is added back and the reclassified basis is depreciated under regular MACRS over the normal 5, 7, and 15-year lives, not expensed in Year 1.
On a $750K Georgia rental with $600K depreciable basis and 18.3% reclassified to shorter-life property, the reclassified components generate about $109,800 of federal Year-1 depreciation. At a 37% federal bracket, that is about $40,600 of federal savings from the reclassified components alone; including regular depreciation on the remaining building basis, total illustrative Year-1 federal savings are about $43,900.
Cost seg still helps at the Georgia level, because it moves basis into the shorter 5, 7, and 15-year lives (faster Georgia recovery), just without the Year-1 bonus. Georgia levies a flat individual income tax (rate declining under HB 1437 toward 4.99%), so the state-side timing effect is smaller than the federal benefit, and current-year federal usability still depends on passive-loss, at-risk, basis, and business-interest limits.
Federal vs Georgia, Side by Side
For an individual investor's cost-segregation-reclassified components:
| Tax provision | Federal (IRC) | Georgia |
|---|---|---|
| Bonus depreciation under §168(k) | 100% may apply to qualified property acquired and placed in service after January 19, 2025, subject to §168(k) eligibility, related-party/prior-use, binding-contract, and election rules | No Year-1 bonus. Georgia does not adopt §168(k); the federal bonus is added back and reclassified basis recovers over the normal MACRS lives |
| Individual income tax on rental income | Ordinary rates, up to 37% | Flat individual rate, declining under HB 1437 toward 4.99%, on net rental income and business profits |
| State depreciation treatment of reclassified basis | Year-1 bonus on eligible components, then MACRS on the remainder | Federal bonus added back; reclassified basis recovers over the 5, 7, and 15-year lives for Georgia; faster than 27.5/39-year, but no Year-1 bonus (a timing difference) |
| Federal usability of the deduction | Subject to passive activity, at-risk, basis, and business-interest limits | Same federal limits govern the federal deduction; Georgia applies its own flat individual rate at the state level |
| MACRS asset class lives | 5 / 7 / 15 / 27.5 / 39 yr per Rev. Proc. 87-56 | Reclassified components recover over the shorter 5 / 7 / 15-year lives under regular MACRS for Georgia |
| Georgia federal conformity | Not applicable | Georgia decouples from §168(k) bonus depreciation under O.C.G.A. §48-1-2 and requires an add-back |
| Depreciation form the individual files | Form 4562 → Schedule E (rental) or Schedule C (active business) | Georgia Form 500 with the federal bonus added back, recovering basis over the shorter lives without the Year-1 bonus |

How Georgia's add-back affects your cost segregation study
The study itself does not change. The same engineering-based reclassification, using nationally-recognized 2026 construction cost data, MACRS classification per Rev. Proc. 87-56, and IRS Pub 5653 ATG-aligned documentation, produces the same component schedule whether the property sits in Georgia, Texas, or anywhere else. What changes is what happens at the state level: for Georgia, the federal §168(k) bonus is added back, so the reclassified basis is recovered over the normal 5, 7, and 15-year lives rather than expensed in Year 1.
Your CPA receives the same Cost Seg Smart engineered report, the same Form 4562-ready schedule, and the same Form 3115 §481(a) section if this is a lookback study. The components then run through two calculations:
- Federal book: bonus depreciation on eligible 5/7/15-year components in Year 1, plus half-year-convention MACRS on the 27.5-year residential (or 39-year commercial) remainder, subject to the federal passive-loss, at-risk, basis, and business-interest limits.
- Georgia book: no Year-1 bonus. The federal bonus is added back, and the same reclassified components recover over the 5, 7, and 15-year lives under regular MACRS, which is still faster than leaving that basis in the 27.5-year or 39-year shell. Because Georgia levies a flat individual rate, the state-side timing benefit is smaller than the federal benefit.
The practical point is that cost segregation still helps in Georgia on both fronts: the full federal Year-1 bonus is claimed on the federal return, and for Georgia the reclassified basis recovers faster because it sits in the shorter 5, 7, and 15-year lives. How much of the federal deduction you actually use in the current year still depends on your passive-loss, at-risk, basis, and business-interest situation.
Illustrative numbers: $750K Georgia rental
An illustrative example using the Cost Seg Smart residential benchmark (SFR reclass 18.3%) and 100% federal bonus depreciation for eligible components under current law. Headline dollar figures are federal; the Georgia column is described qualitatively because Georgia adds the federal bonus back and recovers the reclassified basis over the asset lives rather than in Year 1:
| Line item | Federal | Georgia |
|---|---|---|
| Purchase price | $750,000 | $750,000 |
| Land allocation (20%) | $150,000 | $150,000 |
| Depreciable basis | $600,000 | $600,000 |
| Reclassified to 5/7/15-yr (18.3% SFR benchmark) | $109,800 | $109,800 |
| Year-1 deduction on reclassified components | $109,800 (100% bonus, if eligible) | Federal bonus added back; the $109,800 recovers over 5, 7, and 15-year lives (faster than 27.5-year) |
| Federal savings from reclassified components alone | ~$40,600 (37% × $109,800) | Georgia benefit spread over the 5, 7, and 15-year lives; smaller at the flat individual rate |
| Year-1 depreciation on remaining 27.5-yr basis | ~$8,909 | Same 27.5-year recovery on the remaining shell basis |
| Total Year-1 federal depreciation | ~$118,700 | Recovery spread over the asset lives for Georgia after the add-back |
| Marginal tax rate | 37% | Flat individual rate, declining under HB 1437 toward 4.99% |
| Illustrative Year-1 federal tax savings | ~$43,900 (37% × ~$118,700) | Faster Georgia recovery of the reclassified basis; state timing benefit smaller at the flat rate |
| Cost Seg Smart study cost | $995 (residential under $1M basis) | |
| ROI on $995 study fee (illustrative, federal savings) | ~44× | |
The headline dollars above are federal. For Georgia the federal bonus is added back, so the reclassified basis is recovered over the 5, 7, and 15-year lives, which is still faster than the 27.5-year shell, and at the flat individual rate the state timing benefit is smaller than the federal benefit. Whether the full federal deduction is usable in the current year depends on your passive-loss, at-risk, basis, and business-interest situation. Figures are illustrative; your result depends on basis, land allocation, bracket, and eligibility.

Forms your CPA files for a Georgia property
For an individual Georgia investor, the workflow runs on both the federal return and the Georgia Form 500, because Georgia does tax rental income at a flat individual rate:
- Federal Form 4562: depreciation and amortization, including the §168(k) bonus deduction on eligible reclassified components. Flows to Schedule E (rental) or Schedule C (active business).
- Schedule E (or Schedule C): the accelerated federal deduction reduces federal taxable income in Year 1, subject to the federal passive-loss, at-risk, basis, and business-interest limits.
- Georgia Form 500: the federal bonus is added back for Georgia, so the reclassified basis recovers over the 5, 7, and 15-year lives under regular MACRS, taxed at Georgia's flat individual rate (declining under HB 1437 toward 4.99%).
- Form 3115 §481(a) section: included only if this is a federal lookback method change on a property placed in service in a prior year (see below).
The reclassified schedule is the same engineered output for both books; the difference is that federal claims the Year-1 bonus while Georgia adds it back and recovers the same basis over the shorter class lives.
Form 3115 lookback on a Georgia property
If the property was placed in service in a prior tax year and depreciation was reported using a non-segregated method, a federal Form 3115 (Application for Change in Accounting Method) may allow a current-year §481(a) catch-up adjustment for the accelerated depreciation you missed, generally without amending prior returns. This is often the single biggest acceleration mechanism in cost segregation. Any catch-up dollars are illustrative and depend on placed-in-service date, prior depreciation claimed, bonus eligibility, land allocation, and component mix.
The federal §481(a) catch-up is the primary lever, and it remains subject to the federal passive-loss, at-risk, and basis limits. For Georgia, the effect follows Georgia's own recovery of the reclassified basis over the 5, 7, and 15-year lives after the federal bonus is added back, so the Georgia-side timing benefit is smaller than the federal benefit at the flat individual rate.

Should you skip cost segregation in Georgia? No.
Georgia's add-back changes the timing of the state-side benefit, not the fundamental economics. The math still favors doing the study, for three reasons:
- The full federal Year-1 bonus is intact. Georgia does not reduce the federal deduction; the full §168(k) bonus is claimed on the federal return. How much you use in the current year still depends on your passive-loss, at-risk, basis, and business-interest situation.
- Cost seg still accelerates Georgia recovery. For Georgia there is no Year-1 bonus, but moving basis into the shorter 5, 7, and 15-year lives still recovers it faster than leaving it in the 27.5-year or 39-year shell. At the flat individual rate, that state timing benefit is smaller than the federal benefit but real.
- The Form 3115 lookback captures missed years. If the property was placed in service in a prior year and depreciated without cost segregation, the federal §481(a) catch-up may be available, generally without amending prior returns.
The nuance to flag with your CPA is the Georgia add-back: because Georgia decouples from §168(k) under O.C.G.A. §48-1-2, the federal bonus is added back and the reclassified basis recovers over the shorter class lives on the Georgia return. The federal benefit remains the dominant driver, subject to the taxpayer's passive-loss, at-risk, and basis situation.
Frequently asked
Does Georgia conform to bonus depreciation?
No. Georgia does not adopt federal §168(k) bonus depreciation (O.C.G.A. §48-1-2). An individual investor still claims the full federal Year-1 bonus on the federal return (100% may apply to qualified property acquired and placed in service after January 19, 2025, subject to §168(k) eligibility, related-party/prior-use, binding-contract, and election rules), but for Georgia income tax the federal bonus is added back and the reclassified basis is depreciated under regular MACRS over its normal life, not as a Year-1 bonus. That is a timing difference, not a lost deduction: the same reclassified basis still recovers over the shorter 5, 7, and 15-year lives for Georgia, just without the Year-1 bonus.
Does Georgia tax my rental income?
Yes. Georgia imposes a flat individual income tax (with the rate declining under 2022's HB 1437 toward 4.99%) on Georgia taxable income, which includes net income from rental real estate and business profits. So unlike a no-income-tax state, a Georgia investor does have a state return on which depreciation matters. Because the flat rate is well below the top federal bracket, the Georgia-side timing of the deduction is smaller than the federal Year-1 benefit, but it is still real.
How does the Georgia add-back work for a cost segregation study?
The study is the same everywhere: the engineering-based reclassification moves building components into shorter MACRS class lives (5, 7, and 15-year) per Rev. Proc. 87-56. On the federal return, eligible reclassified components may take 100% §168(k) bonus in Year 1. For Georgia, that federal bonus is added back on the state return, and the same reclassified basis is depreciated under regular MACRS over the 5, 7, and 15-year lives rather than expensed up front. Cost seg still helps at the Georgia level, because it moves basis out of the 27.5-year (residential) or 39-year (commercial) shell and into the shorter 5, 7, and 15-year lives, which recover faster for Georgia. You keep the full federal Year-1 benefit and gain faster Georgia recovery, just without a Georgia Year-1 bonus.
Is cost segregation still worth it in Georgia?
In nearly every case, yes. The federal Year-1 benefit is overwhelmingly the dominant driver, and Georgia does not reduce it: the full federal bonus is claimed on the federal return. At the Georgia level, cost segregation still accelerates recovery by shifting basis into the shorter 5, 7, and 15-year lives, and because Georgia levies a flat rate the state-side timing effect is smaller than the federal benefit either way. On a $750,000 rental with a $600,000 depreciable basis and 18.3% reclassified, roughly $109,800 moves into shorter-life property; at a 37% federal bracket that is about $40,600 of federal savings from the reclassified components alone, with total illustrative Year-1 federal savings of about $43,900. Whether you can use the full federal deduction in the current year still depends on federal passive-activity, at-risk, basis, and business-interest limits.
Can I use Form 3115 on a Georgia property I bought years ago?
Often, yes, at the federal level. If the property was placed in service in a prior tax year and depreciation was reported using a non-segregated method, a federal Form 3115 (Application for Change in Accounting Method) may allow a current-year §481(a) catch-up for the accelerated depreciation you missed, generally without amending prior returns. Any catch-up dollars are illustrative and depend on placed-in-service date, prior depreciation, bonus eligibility, land allocation, and component mix. The federal §481(a) mechanics are the primary lever; the Georgia effect follows Georgia's own recovery of the reclassified basis over the 5, 7, and 15-year lives after the federal bonus is added back.
What is Georgia's income tax rate on rental income?
Georgia levies a flat individual income tax, with the rate declining under 2022's HB 1437 on a schedule that phases toward 4.99%. It applies to Georgia taxable income, including net rental income and business profits, and there are no graduated brackets under the flat structure. Because the rate is flat and well below the top federal bracket, the state-side depreciation timing question is smaller relative to the federal deduction, where ordinary rates can reach 37%.
What does a Georgia cost segregation study rely on for its numbers?
The study reclassifies building components into IRS-recognized MACRS class lives (5, 7, and 15-year) per Rev. Proc. 87-56, using an engineering-based methodology that follows the IRS Cost Segregation Audit Techniques Guide (Publication 5653). The reclassified components may then qualify for federal §168(k) bonus depreciation on the federal return (100% for qualified property acquired and placed in service after January 19, 2025, subject to eligibility and election rules), while for Georgia the federal bonus is added back and the same components recover over the 5, 7, and 15-year lives. The engine ships our own calibrated, nationally-recognized construction cost data.
