Income Tax Exemption for Teacher Pensions

Per the 2019 Connecticut Resident Income Tax Return Instructions, for taxable years beginning on or after January 1, 2019 in determining a taxpayer’s Connecticut AGI, a taxpayer is allowed a subtraction modification of 25% 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.
