  Updates

Important: Beginning with taxable year 2015, individual taxpayers who had a Connecticut income tax liability of $4,000 or more for taxable year 2013, and who are required to, or voluntarily make estimated tax payments for taxable year 2015, must make such payments by electronic funds transfer (EFT).

 

You are required to make estimated income tax payments if your 2015 Connecticut income tax (after tax credits) minus Connecticut tax withheld is $1000 or more, and you expect your income tax withheld to be less than your required annual payment for the 2015 taxable year.

 

Your required annual payment for the 2015 taxable year is the lesser of:

  • 90% of the income tax shown on your 2015 Connecticut income tax return; or
  • 100% of the income tax shown on your 2014 Connecticut income tax return if you filed a 2014 Connecticut income tax return that covered a 12-month period.
