ID S1048

Revises the calculation method for taxing district budget increases by requiring the highest dollar amount of property taxes certified in any of the three preceding tax years, plus a growth factor based on consumer price index (not to exceed 3%), plus revenue from new construction and annexation.

Adds a provision allowing taxing districts to choose a 3% increase if the sum of base amount, CPI growth, and new construction/annexation revenue is less than 3%.

Establishes a 4% maximum total increase cap for paragraphs (a) and (e) without voter approval, requiring 66⅔% voter approval to exceed this limit.

Clarifies that school district levies imposed under section 33-802, Idaho Code, and cooperative services agency levies under sections 33-315 through 33-318, Idaho Code, are not subject to these budget limitations.

Maintains existing provisions allowing nonschool districts to recover forgone increases, cities with low levies to increase budgets with 60% voter approval, and fire districts to increase budgets when public utilities consent to fire protection services.
