Selling an investment while living in Georgia triggers two taxes: the federal capital gains tax and Georgia’s flat state income tax. Because Georgia offers no break for long-term gains, the state side is simply your flat rate. This calculator combines both so you can see the full cost of a sale.
How it works
The federal treatment depends on how long you held the asset. Long-term gains (held more than a year) use preferential rates that stack on your other taxable income:
0% up to $47,025 single / $94,050 joint of total income
15% from there up to $518,900 / $583,750
20% above those thresholds
Short-term gains (held a year or less) are taxed at your ordinary federal rate. A 3.8 percent net investment income tax applies to gains above $200,000 single or $250,000 joint of modified AGI. Georgia then taxes the entire gain as ordinary income at its flat 5.39 percent.
Example
A single filer with $80,000 of other income and a $20,000 long-term gain has already used the 0 percent band, so the federal gain is taxed at 15 percent ($3,000). Georgia adds 5.39 percent ($1,078). Total tax on the gain is about $4,078, leaving roughly $15,922 after tax.
Notes
This is a simplified model. Real returns involve loss carryovers, the exact NIIT calculation, qualified dividends, and Georgia’s retirement and personal deductions, none of which are fully modeled. Use it for planning and confirm with irs.gov and dor.georgia.gov.
