What’s changing for Colorado businesses in 2026
A new year brings a fresh batch of tax and compliance changes. Here is what Colorado small-business owners should have on their radar heading into 2026.
Every January resets a handful of rules, rates, and thresholds, and the ones that matter to your business are easy to miss until they cost you. Here is a plain-language rundown of what Colorado small-business owners should be aware of heading into 2026 — not an exhaustive legal brief, but the items most likely to touch your books.
The sales-tax vendor fee change
A notable change for retailers: Colorado has moved to eliminate the state-level vendor fee — the small percentage of collected sales tax that retailers were previously allowed to keep for remitting on time. Practically, that means the state portion you remit may go up slightly because you no longer retain that fee, though some local jurisdictions may still offer their own. If you collect sales tax, make sure your filings reflect the current treatment.
Minimum-wage adjustments
Colorado’s minimum wage adjusts at the start of each year for inflation, and several localities — Denver among them — set their own higher minimums that also rise on January 1. If you have employees, especially tipped staff, confirm you are paying the current 2026 rate for every city your team works in. Underpaying because you are running last year’s number is a common and avoidable mistake.
Payroll program rates
Payroll-funded programs reset their parameters annually too. FAMLI premium rates and wage bases, the Social Security wage base, and Colorado’s unemployment (SUTA) wage base are all worth confirming for 2026 so your withholding and employer contributions are correct from the first payroll of the year.
The usual federal inflation adjustments
Federally, the standard mileage rate, retirement-contribution limits, standard deduction, and tax brackets all shift for inflation each year. None of these are dramatic on their own, but they affect your planning and your estimates — and the retirement-limit increase in particular is worth taking advantage of.
Most year-one changes are small individually and add up quietly. The cost is rarely any single adjustment — it is running all of last year’s numbers into the new year and finding out in April.
The bottom line
Heading into 2026, the items most likely to touch your business are the sales-tax vendor-fee change, the January wage and payroll-rate adjustments, and the usual federal inflation updates. Make sure your payroll and sales-tax setup reflect the current numbers from the first of the year. If you would rather not track all of this yourself, keeping clients ahead of it is a core part of what we do.
