At Monday’s triboard meeting, First Selectwoman Lynne Vanderslice presented a handout with details of the grand list to the Board of Finance and Board of Education for them to keep in mind as the budget process progresses.
Under the new grand list, about half the homes in Wilton will see an increase in value while the other half will see a decrease.
“I wanted all the boards to understand the impact will be disproportional,” Vanderslice said following the meeting.
She said it was most unusual for half the town to go up in assessed value (70% of market value) while the other half went down in value. “Residents should understand this, so it comes as no surprise to them when they get their tax bills on July 1,” she said.
The time to appeal tax assessments is over; the deadline was March 20. “Whatever that valuation is, stands,” said Vanderslice.
The residential portion of the grand list is down 4.08%, Vanderslice explained in the handout. The valuations are from Oct. 1, 2018.
She noted that neighboring Weston has experienced a 6.3% decline in its grand list and New Canaan has experienced a 7.1% decline based on valuations of Oct. 1, 2018.

Just over 2,500 single-family homes, or 47% of all single family homes in Wilton, are up in value, according to the handout.
