In Connecticut, sellers of homes and land have to pay a conveyance tax of .75% (three quarters of a percent) to the state treasury, for properties sold for up to $800,000. For more expensive properties, the tax goes up to 1.25% for that amount over the $800,000. This tax is payable at the time of sale.
In addition to the state, your local municipality wants it share too. The minimum conveyance tax in a town is .25%, with 17 towns charging .5%. You need to check the rate in your town.
Whether you call it a sales tax or a conveyance tax, it's going to cost you at least 1% of the sales price for taxes.
