The short answer, then the decision
Georgia reached its statutory target rate for 2026: a flat 4.99%, down from 5.39% in 2024 and 5.19% in 2025 after successive legislative accelerations. Paired with a generous standard deduction of $15,000 single and $30,000 married filing jointly, Georgia’s effective rates now undercut its historical reputation as a middling-tax Southeast state. The calculator above applies the 2026 rate and deduction.
Atlanta is one of the largest physician and traveling-professional markets in the country, and the multi-state patterns dominate our Georgia work: locums based in Georgia taking assignments across the Southeast, out-of-state physicians covering Georgia facilities, and households weighing a Georgia base against no-tax Florida and Tennessee next door. Georgia has no reciprocity with any state, so all of it runs through nonresident returns and the resident credit.
Georgia’s $30,000 married standard deduction wipes state tax off the first $30,000 of income entirely, worth about $1,500 per year at the flat rate. For dual-income professional couples, that deduction plus the flat 4.99% produces effective rates in the low-to-mid 4s, close enough to neighbors like North Carolina that the income tax rarely decides the location; the practice opportunity should.

The 2026 rate: flat 4.99%, target reached
Three cuts in three years
Georgia replaced its graduated brackets with a flat tax in 2024 at 5.39%, cut to 5.19% for 2025 under HB 111, and reached the statutory target of 4.99% for 2026 per the Georgia Department of Revenue. Barring new legislation, 4.99% is the settled rate.
The 2026 standard deduction is $15,000 for single filers and $30,000 for married filing jointly. Georgia taxable income starts from federal AGI with state adjustments, minus the deduction, times 4.99%.
Because the deduction is fixed while the rate is flat, effective rates climb toward 4.99% as income rises: a $100,000 single filer pays an effective 4.2%, a $250,000 filer about 4.7%, and a $1 million filer essentially the full rate. That is the shape to keep in mind when comparing Georgia against graduated states, whose effective rates climb much faster over the same range.

Worked example
Worked example: $250,000 income, single Georgia filer (2026)
- Georgia taxable income after $15,000 standard deduction
- $235,000
- Georgia tax at 4.99%
- about $11,727
- Same income at the 2024 rate structure (5.39%)
- about $12,667
- Effective rate on gross income
- about 4.7%

Withholding setup: Form G-4
Flat-rate withholding with a deduction built in
Georgia employees set state withholding on Form G-4. With a flat rate and a large standard deduction, wage withholding is close to self-correcting for single-employer households once the G-4 status is right. Supplemental wages such as bonuses are withheld in line with the flat rate under DOR employer guidance, so state-level bonus surprises are modest.
The usual gap is unwithheld income: 1099 locum pay, K-1 distributions, and investment income need quarterly estimated payments to Georgia. At a flat 4.99%, the reserve math is simple: roughly 5% of net Georgia-taxable self-employment income, set aside alongside the far larger federal share.
Taxstra Tip
Dual-income Georgia couples should coordinate G-4 elections so the $30,000 married deduction is not effectively claimed by both employers’ withholding tables at once. One spouse claiming it while the other withholds at the flat rate keeps the annual reconciliation close to zero.
Multi-state physicians with a Georgia base
No reciprocity, Florida and Tennessee next door
Georgia has no reciprocity agreement with any state. Georgia-based locums file nonresident returns in every taxing assignment state and claim a Georgia credit for tax paid there, capped at Georgia’s 4.99% on the same income. Higher-rate assignment states cost the excess; assignments in Florida and Tennessee, which tax no wage income, simply pay Georgia.
The border geography creates a live relocation question: a physician who can base in Jacksonville or Chattanooga instead of Atlanta eliminates the resident-state layer entirely. On $400,000 of income, Georgia’s roughly 4.7% effective rate is about $18,500 per year, which is the honest price tag of the Atlanta base. Whether the market, group, and life in Atlanta are worth it is the real decision; tax just prices it.
Out-of-state physicians covering Georgia assignments owe Georgia nonresident tax on Georgia-source income. Agencies rarely withhold Georgia tax on 1099 pay, so quarterly estimates to Georgia are on the physician.
The credit floor is worth seeing in numbers. A Savannah-based locum earns $120,000 on a North Carolina assignment: North Carolina takes 3.99%, about $4,788, on a nonresident return. Georgia’s tax on that income at 4.99% is about $5,988, so the Georgia credit absorbs the full North Carolina payment and Georgia collects the remaining $1,200. Total state cost: $5,988, exactly what staying home would have cost. Now run the same $120,000 in Florida: no assignment-state tax, and Georgia still collects its $5,988. The lesson cuts against intuition: for a Georgia resident, lower-rate assignment states do not lower the total bill, because the home state back-fills to its own rate. Only the paperwork changes.
Telehealth into Georgia does not automatically create Georgia tax
Physical presence still drives wage and service sourcing in most cases: seeing Georgia patients remotely from a Tennessee home is generally Tennessee-source work, while on-site coverage in a Georgia facility is Georgia-source. Contracts that mix both need day-level records to allocate defensibly.
Georgia against its neighbors
The Southeast comparison set
Within the Southeast, 2026 Georgia (4.99% flat) sits just above North Carolina (3.99% flat) and below South Carolina’s top graduated rate, with Florida and Tennessee at zero. Against the other flat states in our calculator series, Georgia is a hair above Illinois (4.95%) and well above Colorado (4.4%), Pennsylvania (3.07%), and Ohio (2.75%).
Georgia also carries no local income taxes and moderate property taxes, so the all-in wage-tax stack is genuinely one number: 4.99% after the deduction. Sales tax lands mid-pack: 4% at the state level and 7.56% combined with local rates on average as of July 1, 2026 per Tax Foundation data. For retirees, Georgia layers a substantial retirement income exclusion on top, which is covered on our Georgia retirement taxes page.
One more comparison worth making explicit: against North Carolina, the other big Southeast professional market, Georgia’s rate disadvantage is exactly one percentage point (4.99% versus 3.99%), or about $2,350 per year on $235,000 of taxable income. Against Florida and Tennessee it is the full 4.99%. Those are the honest brackets around the location decision, small enough that practice economics should dominate, large enough to deserve a line in the comparison spreadsheet.
Who actually needs planning here
An honest scope
A single-employer W-2 household living and working in Georgia is nearly fully served by a correct G-4: one rate, no local layer, matching bonus withholding. The planning population is multi-state clinicians, 1099 earners with no withholding, practice owners running the federal S-corp analysis with Georgia layered on, and households genuinely on the fence between a Georgia base and the no-tax states one state away.
Who should get a full-year projection
The Georgia fact patterns that outgrow the calculator
Four Georgia profiles consistently benefit from a full-year projection. Locum and travel physicians rotating through Southeast assignment states, who need per-state estimates, a day log, and credits that reconcile against Georgia’s 4.99% floor. Practice owners and 1099 clinicians running the S-corp analysis, where reasonable compensation, QBI, and payroll costs are federal questions but the flat Georgia rate flows through every scenario. Households seriously weighing a Florida or Tennessee move, where the projection separates the real, sourced savings from the headline rate. And new Georgia residents with equity or bonuses still allocated to a former state, whose first Georgia year is really a two-state year.
A realistic scenario: an Atlanta anesthesiologist earns $310,000 W-2 from a hospital system, $95,000 of 1099 call coverage split between Alabama and Florida facilities, and has RSUs still vesting from a former California employer. The projection runs an Alabama nonresident return with a capped Georgia credit, Georgia-only tax on the Florida income, a California allocation on each remaining vest, quarterly estimates to two states, and a G-4 check so the household’s two earners are not both claiming the $30,000 deduction. Each piece is fifteen minutes with the facts in hand, and none of it is visible from a paystub.
What to check before you act
A practical review sequence for the return, books, or planning file.
Confirm your G-4 filing status and coordinate the married deduction across two earners.
Reserve roughly 5% of net self-employment income for Georgia quarterly estimates.
Locums: keep day-and-dollar records per assignment state; each taxing state gets a nonresident return with a Georgia credit capped at 4.99%.
Out-of-state physicians on Georgia assignments: set up Georgia estimated payments; agencies will not.

Common mistakes
The shortcuts most likely to produce a confident but wrong answer.
Using a stale rate in projections
Georgia’s rate has changed each year for three years. Withholding or estimates keyed to 5.19% or 5.39% overpay in 2026, and older planning spreadsheets quietly misprice relocation comparisons.
Double-claiming the married deduction through withholding
When both employers’ tables assume the full $30,000 deduction, the couple is underwithheld by up to about $1,500. A one-line G-4 coordination fixes it.
Skipping assignment-state returns because Georgia was paid
The work state has first claim on income earned there. Georgia’s credit only functions if the nonresident return exists to support it.
Ignoring estimates on 1099 income
Flat-rate wage withholding lulls physicians into forgetting that locum pay carries zero state withholding. The April balance arrives with underpayment interest attached.
Letting the tax tail wag the location decision
The Georgia-versus-Florida differential is real but bounded: roughly 4.7% effective on income. Choosing the weaker practice opportunity to save it is usually a losing trade, and an honest calculator shows both numbers.
