The Connecticut income tax applies to Connecticut residents, part-year residents, and nonresidents who have income from Connecticut sources. The tax is computed on your Connecticut taxable income.
See the Connecticut instruction booklets for Form CT-1040, Connecticut Resident Income Tax Return, and Form CT-1040NR/PY, Connecticut Nonresident and Part-Year Resident Income Tax Return.
Income Tax Return: For calendar year filers, the Connecticut income tax return is due on or before April 15 of the next calendar year. If you are not a calendar year filer, your return is due on or before the fifteenth day of the fourth month following the close of your taxable year. If the due date falls on a Saturday, Sunday, or legal holiday, the Connecticut income tax return will be treated as timely if the return is mailed or transmitted on the next business day. You may be required to file an income tax return even if you do not owe any tax. Information on filing requirements is included in all Connecticut income tax instruction booklets. Residents must file Form CT-1040 and nonresidents and part-year residents must file Form CT-1040NR/PY.
Income Subject to Tax: Generally, income included in your federal adjusted gross income is subject to Connecticut income tax and income excluded from your federal adjusted gross income is not subject to Connecticut income tax. For example, interest from Connecticut state or local bonds is not subject to federal or Connecticut income tax. Likewise, the gain from the sale of your primary residence is subject to Connecticut income tax only to the extent it is subject to federal income tax.
Modifications to Federal Adjusted Gross Income: Certain income is treated differently for Connecticut income tax purposes than it is for federal income tax purposes.
You must make the appropriate modifications to your federal adjusted gross income to compute your Connecticut adjusted gross income (AGI) if you have:
Allowable modifications are explained in the instruction booklets for Form CT-1040 or Form CT-1040NR/PY. See the section for Schedule 1.
Filing Status Options: The Connecticut filing status options are single, filing jointly for federal and Connecticut, filing jointly for Connecticut only, filing separately for federal and Connecticut, filing separately for Connecticut only, head of household, and qualifying widow(er) with dependent child.
Any reference in this publication to filing jointly includes filing jointly for federal and Connecticut and filing jointly for Connecticut only. Likewise, filing separately includes filing separately for federal and Connecticut and filing separately for Connecticut only.
Tax Rate: The rate of tax for Connecticut taxable income for single filers and taxpayers filing separately is:
The rate of tax for Connecticut taxable income for head of household filers is:
The rate of tax for Connecticut taxable income for taxpayers filing jointly and qualifying widow(er) with dependent child is:
Taxable Income: To compute your Connecticut taxable income, subtract your personal exemption from Connecticut AGI. If your Connecticut AGI is less than or equal to the maximum personal exemption amount for your filing status, you do not owe any Connecticut income tax.
Maximum personal exemption amounts are:
$12,000 filing separately
For every $1,000 (or part of $1,000) of Connecticut AGI over $24,000, the personal exemption amount is reduced by $1,000.
$13,000 single filers (for 2010 through 2011 taxable years)
For every $1,000 (or part of $1,000) of Connecticut AGI over $26,000, the personal exemption amount is reduced by $1,000.
$19,000 head of household
For every $1,000 (or part of $1,000) of Connecticut AGI over $38,000, the personal exemption amount is reduced by $1,000.
$24,000 filing jointly or qualifying widow(er) with dependent child
For every $1,000 (or part of $1,000) of Connecticut AGI over $48,000, the personal exemption amount is reduced by $1,000.
Computing Your Income Tax: The example below shows how to compute the income tax liability for a resident couple filing jointly. The tax is rounded to the nearest whole dollar.
Property Tax Credit: A property tax credit is also available to resident individuals for property taxes paid to a Connecticut political subdivision on a primary residence, a motor vehicle, or both. Generally, this credit is allowed for property tax bills first becoming due during a taxable year and paid during the taxable year. The maximum property tax credit is $500 per return for the 2010 taxable year. Depending on the amount of property taxes you paid to a Connecticut municipality and your Connecticut AGI, the property tax credit may be reduced or you may not be eligible for a credit. The amount of credit is reduced by 10% for each $10,000 or fraction of $10,000 increase in Connecticut AGI. The property tax credit AGI limitation of is $56,500 for any taxpayer who files as single for the 2010 and 2011 taxable years.
Spouses or civil union partners who file a joint Connecticut income tax return may include property tax bills for which each spouse is individually or jointly liable. If you are claiming a property tax credit, you must complete and attach the property tax schedule to your return or the DRS will disallow your credit.
See Informational Publication 2010(23), Q & A: Income Tax Credit for Property Taxes Paid to a Connecticut Political Subdivision.
Credit for Income Taxes Paid to a Qualifying Jurisdiction: If you are a resident of Connecticut and any part of your income was taxed by a qualifying jurisdiction or if you are a part-year resident of Connecticut and any part of your income earned during the residency portion of your taxable year was taxed by a qualifying jurisdiction, you may be able to claim a credit against your Connecticut income tax liability for qualifying income tax payments you made. See the current year instruction booklets for Form CT-1040 and Form CT-1040NR/PY.
Estimated Income Tax Filing Requirements: You must make estimated Connecticut income tax payments if your Connecticut income tax due after tax credits minus Connecticut income tax withheld is $1,000 or more and you expect your Connecticut income tax withheld to be less than your required annual payment. Estimated payments are generally made in four equal installments: April 15, June 15, September 15 of the current year, and January 15 of the following year.
However, 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. See Informational Publication 2010(27), Estimated Connecticut Income Taxes, and Informational Publication 2010(28), A Guide to Calculating Your Annualized Estimated Income Tax Installments and Worksheet CT-1040 AES.
Alternative Minimum Tax
The Connecticut alternative minimum tax is a tax imposed on certain individuals, estates, and trusts in addition to the regular Connecticut income tax. Taxpayers who are subject to and required to pay the federal alternative minimum tax are subject to the Connecticut alternative minimum tax.
The Connecticut alternative minimum tax is the lesser of:
The tax must be reported on Form CT-6251, Connecticut Alternative Minimum Tax Return—Individuals. See Informational Publication 2005(31), Q & A: The Connecticut Alternative Minimum Tax.
Sales and Use Taxes
A 6% tax is imposed on the sale or rental of most goods and the sale of certain services. However, there are exemptions such as food, all purchases made in the supplemental nutrition assistance program, yarn, utility charges for residential property, household fuel, prescription drugs, compact fluorescent light bulbs, certain nonprescription drugs, clothing under $50, newspapers, magazines by subscription, materials for noncommercial sewing used to make clothing, and Internet access services. Computer and data processing services are taxable at 1%.
When the seller of goods or provider of taxable services does not collect sales tax, the buyer must pay use tax at the same rate as the sales tax. If you purchase goods from mail order, catalog companies, or over the Internet and have the goods shipped to Connecticut, you must pay Connecticut use tax if you did not pay Connecticut sales tax. If you purchase goods at out-of-state locations for use in Connecticut and the tax paid is less than the Connecticut tax, you must pay the difference between the Connecticut tax and the tax paid in the other state. If all the items purchased and brought into Connecticut at one time total $25 or less, you do not have to pay Connecticut use tax. The $25 exemption does not apply to items shipped or mailed to you.
You pay the use tax for purchases you made during the prior calendar year on your Connecticut income tax return or on Form OP-186, Connecticut Individual Use Tax Return, on or before April 15. See Informational Publication 2009(33), Q & A on the Connecticut Individual Use Tax.
