Filing your Connecticut state income tax return

As a resident of Connecticut, the filing status of both your state and federal income tax returns should be the same, unless your spouse has a different state residency than yourself. In these situations, special rules may apply to your filing status. Consult the CT-1040 instructions for further information. (Caution: larger file)

Your Connecticut state income tax return does not include itemized deductions or the standard deduction.

For 2006, Connecticut offers a property tax credit of up to $500. The credit depends upon income level and the property tax paid on real property or motor vehicles. The maximum amount of $500 is reduced for higher income levels.

Connecticut does not have any tax deductions. However, if you itemize your deductions on your 2006 federal income tax return, you can deduct Connecticut income taxes actually paid in 2006.

Connecticut residents are subject to state income tax on pension income to the extent that it is included in federal adjusted gross income, regardless of its source. This means, pension distributions from another state are taxable in Connecticut to the extent they are included in your federal adjusted gross income.

According to Connecticut state income tax laws, capital gains are taxed at the same rate as the rest of your income.

You must file a Connecticut state income tax form if your total income from all sources exceeds 12,500 (single filer) 12,000 (married filing separately), 24,000 (married filing jointly) or 19,000 (head of household).

All wages of a Connecticut resident are subject to the state's income tax, even if the resident works outside of the state. There are rules that limits the amount of tax these individuals must pay.

A special tax table is available for low-income taxpayers reducing their tax payments.

A nonresident or part-year resident who meets the gross income test and who has any income from Connecticut sources must file FormCT-1040NR/PY. A nonresident or part-year resident must include gross income from all sources, not just income earned in Connecticut to determine if the taxpayer meets the gross income test .
