Understanding how ct capital gains tax works is essential for Connecticut homeowners and investors planning their taxes strategically. In Connecticut, capital gains are not subject to any preferential tax rates. Instead, both short-term and long-term gains are taxed as ordinary income.
That means the rate you pay depends solely on your total taxable income and filing status, and ranges from 2 percent to 6.99 percent.
How Connecticut Treats Capital Gains
In Connecticut, you do not benefit from special lower rates for long-term capital gains as you might on the federal level. Every dollar of gain you realize, whether from a sale of stock held briefly or long-term real estate appreciation, is included in your adjusted gross income and taxed using the state’s progressive rates.
Here’s how the state brackets work for single filers:
- $0 – $10,000: 2 percent
- $10,001 – $50,000: 4.5 percent
- $50,001 – $100,000: 5.5 percent
- $100,001 – $200,000: 6 percent
- $200,001 – $250,000: 6.5 percent
- $250,001 – $500,000: 6.9 percent
- Over $500,000: 6.99 percent
For married couples filing jointly and heads of household, the income brackets are adjusted proportionally, but the tax rate schedule remains the same. Importantly, the maximum rate in Connecticut caps at around 6.99 percent, though in certain filings it may effectively round to 7 percent.
Filing Requirements and Key Tips
Connecticut requires you to file and pay capital gains tax regardless of income. There is no general exemption threshold, though a limited exclusion applies for elderly homeowners under specific conditions.
If you are a nonresident selling Connecticut real estate, special rules apply. Nonresidents are taxed at a flat 7 percent rate, although this can be capped relative to federal adjusted gross income. Additionally, a once-in-a-lifetime exemption exists for individuals aged 65 or older selling their principal residence, which may eliminate the tax entirely.
Estimated Payments and Penalties
If your capital gains tax liability exceeds $2,000 within the first five full months of the tax year, you must make estimated payments. If the liability remains above $2,000 by the following February, an additional estimated payment is due. These forms require 100 percent of the tax due to be paid with your filing.
Late payments or filings may result in a 10 percent penalty plus 1.25 percent interest per month, or a flat $50 penalty if there’s no additional tax due.
Federal vs. State: Key Differences to Track
Federally, the tax structure is more favorable for long-term investors:
- Short-term gains are taxed at ordinary income rates, ranging from 10 percent to 37 percent.
- Long-term gains enjoy preferential rates of 0 percent, 15 percent, or 20 percent, depending on your income level.
- High earners may also face the Net Investment Income Tax of 3.8 percent.
But in Connecticut, both long-term and short-term gains are taxed identically through the same bracket system. That difference is crucial when planning your tax strategy.
Staying Compliant and Planning Ahead
To avoid issues and minimize liability, it’s important to:
- Track all your capital gains and record them carefully in your adjusted gross income.
- Consider possible exemptions, such as the principal residence exclusion for elderly individuals.
- Anticipate estimated tax liabilities if your gain will exceed $2,000 and make timely estimated payments.
- If you’re a nonresident seller, confirm whether special filing rules apply.
What’s on the Horizon?
There has been discussion in Connecticut about adding surcharges on capital gains for high-income earners. Proposals range from a 1 percent surcharge to as much as 1.75 percent, targeting millionaires. Supporters argue this would raise revenue for state programs, while critics caution it could drive wealth out of the state. These debates are ongoing and could shape future tax planning strategies.
Summary: What You Should Expect with ct capital gains
You can expect your capital gains in Connecticut to be taxed as ordinary income, without any preferential long-term rates. Brackets start at 2 percent and top out near 6.99 percent. Stay alert about estimated tax filings, nonresident rules, and possible new surcharges in the works. Planning now will help you manage your tax burden effectively and avoid unpleasant surprises.
