Foster officials weigh homestead exemption to limit tax shift caused by Providence Water valuation treaty

Foster finance staff presented a proposal Feb. 8 for a temporary homestead exemption intended to reduce the tax‑shift effect from a treaty that freezes Providence Water’s assessed value at $8,400 per acre.

The town is conducting a statistical revaluation that staff estimate could raise residential assessed values roughly 36–40%. Because Providence Water’s acreage is statutorily or contractually assessed at a stable per‑acre figure, their assessed value will not rise with revaluation; that differential could shift roughly an estimated 1–1.5% of tax burden onto other taxpayers if unaddressed, staff said. The finance speaker described an illustrative homestead exemption — typically 20% in other communities — that would lower assessed value for owner‑occupied residences, reducing the regressive impact of the treaty on residents.

Staff acknowledged administrative considerations: exemptions require an ordinance, forms for owner‑occupancy verification, decisions about whether the exemption is one‑time or ongoing for future owners, and an analysis of fiscal impact. The finance speaker said Providence Water could benefit on the order of tens to a few hundred thousand dollars next year because of the valuation freeze and urged the council to act quickly if it seeks to adopt an exemption before the town sets its mill rate. Council directed staff to research model ordinances and bring back draft language and revenue modeling.

No ordinance vote was taken; staff to return with a draft homestead exemption ordinance, estimated fiscal impact and recommended implementation timeline.
