The Connecticut Income Tax:
Supplemental Information for Senior Citizens
PURPOSE: This informational publication is intended as a general guide to the Connecticut income tax for senior citizens. While it does not answer every question about the tax, it will provide answers to some of the most common inquiries.
I am a resident of Connecticut who is retired. My only income is from a pension, social security benefits and a small amount of interest. Must I pay Connecticut income tax?
In general, income that is taxable for federal income tax purposes is also subject to Connecticut income tax, including income from wages, pensions, interest, dividends, annuities, capital gains, etc.
Is any type of income exempt from Connecticut income tax?
Interest from U.S. Government obligations such as U.S. Savings Bonds or Treasury Notes and interest from State of Connecticut bonds or Connecticut municipal bonds are exempt from Connecticut income tax. Social security benefits that are taxable for federal income tax purposes will also be subject to Connecticut income tax. However, for taxable years 1994 and thereafter, Connecticut income taxation of social security benefits is limited 50 percent of benefits received even if a greater percentage of benefits is subject to federal income tax.
What are the Connecticut personal exemptions?
An unmarried person or a married person filing separately for federal income tax purposes whose Connecticut adjusted gross income is $24,000 or less is entitled to an exemption of $12,000. Married persons filing jointly for federal income tax purposes whose Connecticut adjusted gross income is $48,000 or less are entitled to an exemption of $24,000. An unmarried person filing as a head of household for federal income tax purposes whose Connecticut adjusted gross income is $38,000 or less is entitled to an exemption of $19,000. The exemptions are phased out as income levels increase.
How do I calculate my Connecticut income tax liability?
The tax is figured by starting with your Connecticut adjusted gross income:
Step 1. Deduct the personal exemption
Step 2: Multiply by the tax rate of 4.5% (0.045)
Step 3: Deduct the personal tax credit
EXAMPLE: Taxpayer is married filing jointly.
$30,000.00 Federal Adjusted Gross Income
-24,000.00 Personal exemption
6,000.00 Connecticut taxable income
x 0.045 Tax Rate
- 202.50 Personal credit ($270 x 75%)
$ 67.50 Tax due
I am resident of another state but live in Connecticut part of the year. Do I owe Connecticut income tax?
If you are a resident of another state, you will not be taxed as a Connecticut resident unless you have a permanent place to live here and spend more than 183 days in Connecticut during the year. However, if you earn income in Connecticut from a job performed or business conducted in Connecticut, you will have to pay Connecticut income tax on that income.
I have moved into (or out of) Connecticut during the taxable year. Do I owe Connecticut income tax?
Anyone who moves into (out of) the state is a part-year resident and may owe Connecticut income tax.
I am resident of another state but receive a pension from my former Connecticut employer. Must I pay Connecticut income tax on that income?
For taxable year 1994 and thereafter, income from a pension or retirement plan paid to a nonresident is not subject to Connecticut income tax. However, for taxable years 1991, 1992, and 1993, income from a nonqualified plan connected with former employment in Connecticut is taxable to a nonresident. Interest earned by a nonresident individual from a Connecticut bank is, likewise, not subject to Connecticut income tax.
If I am a Connecticut resident, will Connecticut income tax be withheld from my pension benefits?
Withholding of Connecticut income tax is available if your pension is paid by a company doing business in Connecticut. Your pension payer will send you Form CT-W4P, Withholding or Exemption Certificate. If you want Connecticut income tax withheld, complete the form, and return it to the pension plan administrator.
Retired federal civil service employees may request Connecticut income tax withholding by completing Form CT-W4CS, Request to Withholding Income Tax From Civil Service Annuity, and available from the Department's Forms Unit.
Must I file estimated income tax returns?
If you will owe more than $200 in Connecticut income tax over and above any Connecticut income tax withheld during the taxable year, you should make estimated income tax payments. Use Form CT-1040ES, Individual Estimated Income Tax Coupon. Generally, estimated payments must be made in four installments: April 15, June 15, September 15, and January 15. (Fiscal year filers: follow federal filing dates.) If your income varies throughout the year, you may be able to reduce or eliminate the amount of one or more estimated payments by using the annualized installment method. Request a copy of IP 93(6.1), A Guide to Calculating Your Annualized Estimated Income Tax Installments, from the Forms Unit.
What if I am late in making my estimated tax payments?
Interest will be assessed on late payment or underpayment of estimated income tax. To avoid underpayment charges, you must pay the lesser of 90% of your current year's income tax or 100% of your prior year's Connecticut income tax (provided you filed a prior year's return covering a 12-month period.) Payments may be made through estimated payments, withholding payments or a combination of both.
May I deduct my Connecticut income tax in calculating my federal income tax liability?
If you itemize your deductions for federal income tax purposes, all payments of Connecticut income tax made on or before December 31 of the taxable year are deductible for federal income tax purposes.
What about the Connecticut capital gains, dividends and interest tax?
For taxable years beginning on or after January 1, 1992, there is no longer a separate state tax on capital gains, dividends and interest income. Capital gains, dividends or interest income that is included in Connecticut adjusted gross income remains subject to the Connecticut income tax.
