You may take a credit against your 2020 Connecticut income tax liability for qualifying property tax payments you made on your primary residence and/or privately owned or leased motor vehicle to a Connecticut political subdivision.
Generally, property tax bills that were due and paid during 2020 qualify for this credit. This includes any installment payments you made during 2020 that were due in 2020 and any installments you prepaid during 2020 due in 2021. Supplemental property tax bills that were due during 2020 or 2021 also qualify if paid during 2020. However, the late payment of any property tax bills or the payment of any interest, fees, or charges related to the property tax bill do not qualify for the credit.
Taxpayers who file a joint Connecticut income tax return may include property tax bills for which each spouse is individually or jointly liable.
You may take a credit for a leased motor vehicle if you had a written lease agreement for a term of more than one year and the property tax became due and was paid during 2020 (either by the leasing company or by you). Refer to your January 2021 billing statement from the leasing company in order to determine the amount of property taxes that may be eligible for the credit. If you do not receive a billing statement in January 2021, contact your leasing company for the appropriate property tax information.
Example 1: Lisa received a property tax bill for a motor vehicle listed on her town's October 1, 2018, grand list. The bill was payable in two installments, July 1, 2019, and January 1, 2020. If Lisa paid the January 1, 2020, installment on January 1, 2020, she is eligible to claim it on her 2020 income tax return. If she prepaid it during 2019, she is not eligible to take a credit for it on her 2020 return, but she may have been eligible to take a credit for it on her 2019 return.
Example 2: Mary received a property tax bill for a motor vehicle listed on her town's October 1, 2019, grand list. The bill was payable in two installments, July 1, 2020, and January 1, 2021. Mary is eligible to take a credit for both installments on her 2020 income tax return if she paid both installments during 2020. If Mary waited until January 1, 2021, to pay her second installment, she is not eligible to take a credit on her 2020 return for this installment, but she may be eligible to take a credit for it on her 2021 return.
