What the Windsor Tax Applies To
Most tangible personal property sold inside town limits is taxed at 3.65%: clothing, electronics, household goods, furniture, and the usual retail categories. Prepared food and drinks at restaurants and cafes are taxed as well.
Groceries are where Windsor surprises people. Colorado exempts grocery food from its 2.9% state tax, but Windsor does not. All food and beverages, including groceries for home use, are taxed at the full municipal rate.4Town of Windsor, Colorado. Taxes Machinery and tools, also exempt under state rules, are taxable in Windsor too. If you’ve shopped in another Colorado city where groceries rang up tax-free, Windsor will look different.
Telecommunication services and utilities fall inside the tax base as well. Residential and commercial gas and electric service both carry the 3.65% rate. Renting or leasing tangible personal property is treated the same as a sale.
What’s Still Exempt
The exemption list is shorter than the state’s, but a few categories remain exempt locally. Prescription drugs for humans and prosthetic devices for humans are exempt under Windsor’s municipal code. Purchases by government entities and qualified charitable organizations can be exempt, but the buyer has to present a valid exemption certificate at the time of purchase. Without it, the vendor must collect the full tax. If you aren’t sure whether a specific item qualifies, check with the town’s finance department before assuming the state exemption carries over.4Town of Windsor, Colorado. Taxes
