Boise to propose maximum property tax increase for 2027 amid rising city costs

Boise Plans Maximum Property Tax Increase in 2027 Budget Proposal

Boise city officials are preparing to propose the maximum allowable property tax increase as part of the city’s 2027 budget, citing growing costs that are straining municipal finances. The move would push Ada County homeowners’ tax bills higher at a time when many Treasure Valley residents are already feeling the pressure of years of rising assessments and living expenses.

City leaders have pointed to escalating operational expenses as the driving force behind the proposal. Boise has previously acknowledged being financially constrained as it weighs increases to both taxes and fees to keep city services funded. The maximum increase represents the largest levy adjustment allowed under Idaho law in a single budget cycle.

The proposal is expected to move through the city’s formal budget process in the coming months, giving residents opportunities to weigh in before any final vote. Ada County property owners watching local government spending will want to monitor upcoming city council budget hearings for details on how the additional revenue would be allocated.

What Comes Next: Boise residents can track the 2027 budget process through the city’s official website and attend public hearings to comment on the proposed property tax increase before the city council takes a final vote.
