What Groton charges

Groton is eligible to add a surcharge to its municipal conveyance tax and has not, so it charges the base 0.25%.

The state adds its own tax on top. For a home or condominium it is 0.75% of the first $800,000 of the price, 1.25% of the portion from $800,000 to $2,500,000, and 2.25% of anything above that — see how the brackets work. In most Connecticut residential sales the seller pays both, unless an exemption or a contract term says otherwise; see who pays the conveyance tax.

On Groton’s median home sale of $375,000, that is $2,813 to the state and $938 to the town, or $3,750 in all.
