Income Tax Exemption for Teacher Pensions
Per the 2022 Connecticut Resident Income Tax Return Instructions, a taxpayer is allowed a subtraction modification of 100% of the income received from the State Teachers’ Retirement System. This modification applies to the extent such income is properly included in the taxpayer’s federal AGI for the taxable year.
