Connecticut Capital Gains Tax Rules
In Connecticut, capital gains are subject to a state tax rate of 6.99% in 2026. Taxed as ordinary income. This state tax is separate from — and in addition to — the federal capital gains tax you owe to the IRS.
Understanding Connecticut's capital gains rules is essential for investors, homeowners selling property, and business owners who plan to sell assets. The calculator above computes your estimated federal and Connecticut state capital gains tax based on your sale price, cost basis, holding period, and income.
Federal vs Connecticut Capital Gains Tax
The federal capital gains tax rate depends on your income and how long you held the asset. For long-term gains (held over 12 months), the 2026 federal rates are 0% (income up to $48,350 single / $96,700 MFJ), 15% (up to $533,400 single / $600,050 MFJ), and 20% above those thresholds. Short-term gains are taxed as ordinary income at your marginal federal rate.
Connecticut's 6.99% state rate is applied on top of the federal rate. For example, a Connecticut resident in the 15% federal bracket who realizes a long-term gain would owe 15% federal + 6.99% state = a combined rate of 21.99%. This stacking effect makes state-level planning important for high-gain transactions.
Connecticut Cap Gains Strategies & Exemptions
Several strategies can help Connecticut taxpayers reduce their capital gains tax burden. First, hold assets for more than 12 months to qualify for the lower long-term federal rate. Second, harvest capital losses to offset gains — if you have losing positions, selling them in the same tax year can reduce your net taxable gain. Third, use tax-advantaged accounts (401k, IRA, HSA) to shelter future investment growth from both federal and Connecticut state tax.
For Connecticut homeowners, the federal home-sale exclusion allows you to exclude up to $250,000 (single) or $500,000 (married filing jointly) of gain from the sale of a primary residence, provided you meet the 2-of-5-year ownership and use tests. Taxed as ordinary income — so consult a Connecticut tax professional to understand which exclusions apply to your specific situation.
Always work with a qualified tax professional before executing large asset sales. Tax laws change, and individual circumstances — such as installment sales, like-kind exchanges (1031 exchanges for real estate), or business asset sales — can significantly affect your total tax liability.
