What Taxes Do I Pay When Selling a House in Connecticut?

When you're calculating how much money you could make from selling your home, the sale price is only part of the equation. Connecticut sellers also need to account for closing costs, mortgage payoff amounts, attorney fees, commissions, and taxes that may apply to the sale.
So, what taxes do you pay when selling a house in Connecticut?
One of the primary taxes directly associated with a Connecticut home sale is the real estate conveyance tax, which is generally the seller's responsibility. Property taxes also need to be settled or adjusted as part of the transaction. Depending on how much your home has increased in value and your individual circumstances, capital gains taxes may also become relevant.
Here's what Connecticut home sellers should know.
Connecticut imposes a real estate conveyance tax when real property is transferred by deed or another qualifying instrument. The Connecticut Department of Revenue Services states that the seller is responsible for payment, and the tax must be paid before the deed can be recorded.
This makes conveyance tax different from a potential capital gains tax. It is tied directly to the transfer of the property and is generally part of the seller's closing costs.
For residential dwellings, the current Connecticut state conveyance tax rates are:
These are marginal rates, meaning a home selling for more than $800,000 isn't taxed at the higher percentage on the entire sale price. Only the portion falling within each bracket is subject to that rate.
This becomes particularly important for sellers of higher-priced and luxury homes in markets such as West Hartford, Avon, Farmington, and Simsbury.
Yes. In addition to the state portion of the Connecticut real estate conveyance tax, there is a municipal component paid in connection with the transfer. Connecticut law also permits certain qualifying municipalities to impose an additional municipal conveyance tax.
That means two Connecticut sellers with the same sale price could potentially have somewhat different closing figures depending on where their properties are located.
Your closing attorney can calculate the applicable conveyance taxes for your specific property and transaction.
For homeowners preparing to sell, however, the important takeaway is simple: conveyance tax should be included when estimating your net proceeds rather than treated as an unexpected expense at closing.
Property taxes don't simply disappear when a home changes ownership.
Connecticut property taxes are administered at the municipal level, and tax rates vary by town. During a real estate transaction, the closing figures account for property taxes based on the circumstances of the sale, including amounts already paid or owed.
Depending on when you close and the municipality's tax schedule, adjustments may be made between the seller and purchaser.
This is one reason the amount you see deposited after closing won't simply equal:
Sale price minus mortgage balance.
There are several expenses and adjustments that have to be accounted for before determining what a seller actually walks away with.
Maybe, but many homeowners selling their primary residence qualify to exclude a significant amount of gain from federal income taxes.
The IRS currently allows qualifying homeowners to exclude up to $250,000 of capital gain from the sale of a primary residence. Certain married couples filing jointly may qualify to exclude up to $500,000.
Generally, qualifying for the maximum exclusion involves meeting both an ownership test and a use test. The IRS explains that you typically must have owned the home and used it as your main residence for at least two years during the five-year period ending on the sale date. Additional requirements and exceptions apply.
So if you bought a Connecticut home years ago and are now selling it for substantially more, don't assume that the difference between your purchase price and sale price is automatically a taxable gain.
Another common misconception is that taxable profit is simply:
Sale price minus original purchase price.
The calculation can be more involved.
The IRS explains that determining gain involves the amount realized from the sale and the home's adjusted basis. Your adjusted basis generally begins with your cost of acquiring the property and can be affected by qualifying capital improvements and other adjustments. Selling expenses can also factor into determining the amount realized.
This is particularly relevant for longtime Connecticut homeowners who have invested substantially in their properties.
If you've owned a home for 20 years and completed a major addition, kitchen renovation, new roof, HVAC replacement, or other capital improvements, maintaining records of those improvements can be important when discussing the tax implications of your sale with a qualified tax professional.
Not necessarily.
This is another area where sellers can understandably get confused.
If you sell for $600,000 and still owe $300,000 on your mortgage, that doesn't mean the IRS considers your gain to be $300,000.
Your mortgage payoff affects how much money you receive from the transaction, but it is not how taxable gain is calculated. The IRS looks instead at factors including the amount realized from the sale and your adjusted basis in the property.
That's an important distinction between your taxable gain and your net proceeds.
Before putting your Connecticut home on the market, it helps to separate three different numbers:
Your expected sale price is what you believe the property could sell for.
Your potential taxable gain is a tax calculation based on factors including your basis, amount realized, applicable exclusions, and individual circumstances.
Your estimated net proceeds are what may remain after the mortgage payoff, applicable taxes, closing costs, commissions, attorney expenses, adjustments, and other transaction costs.
Those numbers are not interchangeable.
A seller may have significant equity without having a large taxable gain. Another seller could own the property outright but still have taxes and transaction expenses to account for before determining the amount they'll receive from the sale.
Understanding the financial side of selling a home can make the entire process easier to plan.
Before deciding when to sell, what price you need, or how a move fits into your next step, it helps to have a realistic estimate of what the transaction could actually produce after the major selling expenses are considered.
I can't determine your individual tax liability, and questions about your specific federal or Connecticut income tax situation should always go to your attorney, CPA, or qualified tax professional. What I can do is help you understand your home's current market position and build an estimated seller net sheet so you aren't making a major real estate decision based on the sale price alone.
When you know the likely value of your home and the major costs surrounding the sale, you can start planning your next move with much better numbers.
