What does selling cost by state?
Compare the tax bite.
A rough federal-plus-state illustration using verified 2026 top state rates and supported capital-gain deductions. States whose 2026 treatment has not been verified return “Not calculated” instead of a stale estimate.

How this is calculated
Federal LTCGLong-Term Capital Gains (LTCG)Profit from selling an asset held over one year, taxed at lower preferential rates than ordinary income.Full definition brackets (2026): 0%, 15%, or 20% depending on taxable income (here approximated by the gain itself). Single: 0% up to $49,450, 15% up to $545,500, 20% above. MFJMarried Filing Jointly (MFJ)A tax filing status where a married couple combines their income and deductions on one tax return.: 0% up to $98,900, 15% up to $613,700, 20% above.
State tax: For supported states only, a deliberately rough scenario applies the verified 2026 top rate to the gain after any capital-gain deduction explicitly modeled by this tool. South Carolina applies its 44% net-capital-gain deduction, leaving 56% exposed to the 5.21% top rate. Other supported positive-rate states apply their verified top rate to the full gain. The tool still does not model brackets, credits, local tax, residency, nonresident sourcing, or asset-specific eligibility. Unsupported states fail closed as “Not calculated.” Washington is unsupported because its capital-gains tax has its own deduction and tiered rules.
NIITNet Investment Income Tax (NIIT)A 3.8% extra federal tax on investment income for higher earners (above $200k single, $250k married).Full definition (3.8% above $200k/$250k) is not included. Do not use this tool to estimate a return or make a domicile decision.
