Taxes & Budget

The proposed tax plan is a 2.5% local sales tax and a 4-mill property tax levy. The sales tax rate is lower than Boulder, Longmont, Louisville, and most Front Range municipalities. The property tax does not cover fire, water, or sewer — those continue under existing providers. Any future tax increase requires voter approval under TABOR.

The Case

A sales-tax-led revenue model is a deliberate choice. Niwot’s downtown is a regional destination — events like Rock & Rails, First Friday, and the Honeybee Festival draw visitors from Boulder, Longmont, and beyond. A local sales tax means visitors who use Niwot’s streets, parking, and public spaces contribute to maintaining them. It also gives the town a direct financial incentive to promote downtown vitality: the healthier the commercial district, the stronger the tax base.

The pro forma budget models 14 years of revenue and expenditure projections under conservative assumptions. Revenue comes primarily from the 2.5% sales tax and 4-mill property tax, supplemented by use tax, state-shared revenues, and franchise fees. Groceries are exempt from the local sales tax under Colorado state law.

The budget has been stress-tested through Monte Carlo simulation, modeling thousands of scenarios with varying economic conditions. Even under pessimistic assumptions, the town maintains positive reserves. The road bond is revenue-backed — repaid from sales-tax receipts, not from a new property-tax increase.
