For estates of decedents dying on or after January 1, 2021, but before January 1, 2022, no Connecticut estate tax is due 
from a decedent’s estate if the Connecticut taxable estate is $7.1 million or less. For estates of decedents dying on or after 
January 1, 2022, but before January 1, 2023, no Connecticut estate tax is due from a decedent’s estate if the Connecticut 
taxable estate is $9.1 million or less.
I represent that no Connecticut estate tax will be due from the decedent’s estate. By completing this section and filing it 
in the Probate District having jurisdiction over the decedent’s estate, I am requesting a six-month extension of time to file 
Form CT-706 NT, Connecticut Estate Tax Return (for Nontaxable Estates).
I acknowledge that this extension will not avoid any interest or penalties applicable to the estate in the event that the estate 
is ultimately determined to be subject to the Connecticut estate tax.
Declaration: I declare that the representations contained herein are made under the penalties of false statement. The 
declaration of a paid preparer other than the taxpayer is based on all information of which the preparer has any knowledge.
