Filing Requirements

Estate Tax

This tax applies to estates of decedents dying on or after January 1, 2005. For estates of Connecticut residents or nonresidents owning real or tangible personal property located in Connecticut the following filing requirements apply

  • If the estate is not subject to Connecticut estate tax because the taxable estate is below the threshold, and no Connecticut QTIP election is made, file Form CT-706 NT with the relevant Connecticut Probate Court.
  • If the estate is subject to Connecticut estate tax because the taxable estate is above the threshold, or a Connecticut QTIP election is made, file Form CT-706/709 with the DRS and provide a copy to the Connecticut Probate Court.

The threshold for taxable estates for decedents dying between January 1, 2019, and December 31, 2019, is $3.6 million.
