Proposed tax plan: 2.5% local sales tax + 4-mill property tax levy
The proposed tax plan for an incorporated Town of Niwot is a 2.5% local sales tax and a 4-mill property tax levy. These are the two primary household taxes. For most homeowners, this is a modest and competitive package.
The town’s full pro forma budget also models additional revenue sources — including use tax, retail marijuana tax, and state-shared formula revenues — that apply to Colorado municipalities under existing law. This calculator estimates only the direct cost to households from the two primary taxes.

If You Rent in Niwot
Renters do not pay the property tax directly. Your main cost under incorporation is the 2.5% local sales tax on purchases. For a renter spending $5,000/year on taxable goods (excluding groceries), that comes to about $125/year, or roughly $10/month. Whether any portion of the property levy affects rent over time depends on your landlord and the rental market.
The 4-mill property levy funds roads, land use, administration, and public safety contracting. It does not cover fire, water, or sewer — those continue under existing providers. The 2.5% sales tax is lower than Boulder, Longmont, Louisville, and most Front Range municipalities.
