Least Tax-Friendly

About the only bright spot in Connecticut’s tax picture is that localities can’t add to The Constitution State’s 6.35% sales tax. Real estate taxes are the fourth-highest in the country and the state has not only a gift tax, but a luxury tax. The Nutmeg state is one of Kiplinger’s top ten least tax-friendly states.

Connecticut’s property taxes are the fourth-highest in the U.S., so the $10,000 cap on the federal tax deduction for state and local taxes stings a bit more here. The state-wide average property tax for a $400,000 home is $8,456 per year. However, residents in high-income areas such as Fairfield County typically pay more than $10,000 in property taxes each year, so their federal tax deductions for state and local taxes have been curtailed.

Sales Tax

The state taxes most items at 6.35%, but localities are not allowed to add to that. Jewelry valued at more than $5,000 and clothing, footwear and accessories priced at more than $1,000 per item are taxable at 7.75%.

Income Tax Range

Low: 3% (on up to $20,000 of taxable income for married joint filers and up to $10,000 for those filing individually)

High: 6.99% (on the amount over $1 million for married joint filers and over $500,000 for those filing individually)

Motor Fuel Taxes

Gasoline: $0.3931 per gallon.
Diesel: $0.4650 per gallon.

Property Taxes

In Connecticut, residents pay an average of $2,114 in taxes per $100,000 of assessed home value.

Vehicle Taxes

Sales tax is due at purchase: 6.35% for vehicles under $50,000; 7.75% for those over. In addition, vehicles are subject to an stiff annual levy, whether or not they’re registered for use. The rates are set by individual municipalities. Legislation implemented in 2016 lowered the cap on these levies. For example, the owner of a $20,000 vehicle who lived in Hartford would pay $1,366 annually.

Sin Taxes

Cigarettes and little cigars: $4.35 per pack
Snuff: $3 per ounce
Chewing and smoking tobacco: 50% of the wholesale price.
Vapor products that are closed and unrefillable are taxed at $0.40 per milliter of liquid. Other vapor products are taxed at 10% of the wholesale price.
Cigars: 50% of the wholesale price ($0.50 per-piece cap)

Beer: $0.23 per gallon
Wine: $0.72 per gallon
Liquor: $5.40 per gallon

Inheritance and Estate Taxes

Connecticut has an estate tax with a $3.6 million exclusion, which will rise to $5.1 million on January 1, 2020. The tax due is limited to $15 million.

Connecticut is the only state with a gift tax on assets you give away while you're alive. If you made taxable gifts during the year, state law requires that you file a Connecticut gift tax return to identify such gifts. However, taxes (at rates ranging from 7.8% to 12%) are due only when the aggregate value of gifts made since 2005 exceeds $3.6 million.
