The Montrose County sales tax is 1.75%, layered on top of Colorado’s 2.9% state rate for a combined 4.65% in unincorporated areas. Inside the City of Montrose, city and recreation district taxes push the total to 8.53%. The county portion funds road and bridge work and public safety, and it applies more broadly than the state tax because Montrose County did not adopt several of Colorado’s exemptions.
How the Rate Breaks Down
Every taxable sale in the county stacks at least two layers, and often three:
- Colorado state tax: 2.9%
- Montrose County tax: 1.75%, split between a 1% Road and Bridge tax and a 0.75% Public Safety Improvement tax1Montrose County. Montrose County Sales and Use Tax
- City of Montrose (within city limits only): 3.88%, which is a 3.58% city tax plus a 0.30% Montrose Recreation District tax2City of Montrose. Sales Tax
Inside city limits, the three layers reach 8.53%.2City of Montrose. Sales Tax In unincorporated parts of the county with no municipal overlay, the rate is 4.65%. Other incorporated towns within the county may impose their own local taxes, so the total shifts with the exact address of the sale.
What Montrose County Taxes
Colorado’s sales tax generally covers tangible personal property: physical goods like clothing, electronics, furniture, building materials, and most retail merchandise. Where Montrose County parts ways with the state is on exemptions. The county did not adopt several of the exemptions Colorado offers, so its 1.75% applies to all tangible personal property.1Montrose County. Montrose County Sales and Use Tax
Groceries Are Not Exempt at the County Level
This is the divergence that surprises most shoppers. Colorado exempts food purchased for home consumption from the 2.9% state tax.3Colorado Department of Revenue. Taxable and Tax Exempt Sales of Food and Related Items Montrose County still taxes groceries. A 2020 City of Montrose analysis showed the county’s 1% Road and Bridge portion applying to grocery purchases even though the state portion did not.4City of Montrose. Sales Tax and Groceries Memo Shop inside city limits and the city’s own rate may add on top. Don’t assume your grocery bill is tax-free just because the state exempts it.
Prescriptions and Services
Prescription medications are exempt from Colorado sales tax.3Colorado Department of Revenue. Taxable and Tax Exempt Sales of Food and Related Items Over-the-counter drugs and dietary supplements generally are not. Most professional services stay outside the sales tax, but if a service transfers tangible goods as part of the transaction, the goods portion can trigger the 1.75% county rate.
Digital Goods and Software
Colorado treats software differently depending on how it reaches you. Software delivered electronically, accessed through a cloud application, or loaded onto your device without transferring physical media is exempt from state sales tax.5Colorado Department of Revenue. Sales and Use Tax Topics – Computer Software That covers most SaaS subscriptions and downloaded programs. Software sold on a physical disc, though, is taxable like any retail product.
Colorado separately taxes “digital goods” such as streaming video, downloaded music, and e-books, classifying them as tangible personal property.6Colorado General Assembly. Downloaded Software Exemption Given the county’s broad approach to tangible personal property, sellers of digital goods to Montrose County customers should expect the 1.75% county rate to apply.
Use Tax on Out-of-State Purchases
When you buy from a seller who doesn’t collect Colorado or Montrose County sales tax, you owe use tax at the same rates: 1.75% county plus 2.9% state.1Montrose County. Montrose County Sales and Use Tax This commonly arises with online purchases from smaller vendors, equipment bought at trade shows, or goods shipped in from other states.
Businesses report use tax on their regular sales tax return. Individual residents report it on their Colorado income tax return. Skipping it can surface in an audit and produce back taxes, penalties, and interest at the same rates that apply to late sales tax.
Getting a Colorado Sales Tax License

Filing Returns and Deadlines
The Department of Revenue assigns each business a filing frequency based on how much tax it collects: monthly, quarterly, seasonal, or annual. The deadline is the same pattern regardless: the 20th of the month after the filing period ends.10Colorado Department of Revenue.

Revenue Online is the state’s longstanding portal for entering gross sales, applying exempt deductions, and paying by electronic transfer or credit card.11Colorado Department of Revenue. File Sales Tax on Revenue Online The Sales and Use Tax System (SUTS) is a newer one-stop portal that lets you file for state-collected jurisdictions and participating home-rule cities in a single session, look up rates by address, and check item taxability.12Colorado Department of Revenue.

No More State Service Fee
Colorado used to let retailers keep a small percentage of the state tax they collected as a service fee for filing on time. That ended January 1, 2026. Retailers can no longer retain the state sales tax service fee.13Colorado Department of Revenue. Service Fee Local jurisdictions may still offer their own service fee, so check the Department of Revenue’s DR 1002 publication for Montrose County and the City of Montrose. Filing on time still matters, since late payment disqualifies you from any remaining local service fees.
Penalties and Interest for Late Payment
Missing a deadline is costly. Colorado imposes a penalty of 10% of the unpaid tax plus 0.5% for each month the balance remains outstanding, up to 18%. The minimum penalty is $15, whichever is greater.14Colorado Department of Revenue. Tax Topics – Penalties and Interest
Interest accrues on top. For 2026, the discounted rate is 8%, available if you pay before the state issues a notice of deficiency or within 30 days after one is issued. Wait longer and the rate rises to 11%.14Colorado Department of Revenue. Tax Topics – Penalties and Interest On a $5,000 balance, combined penalty and interest can add more than $1,000 in the first year.
Records and Voluntary Disclosure
Colorado requires retailers to keep books, invoices, purchase records, and sales documentation for at least three years after the tax is due.15Colorado Department of Revenue. Sales Tax Guide That includes exempt-sale records and resale certificates. In an audit, the burden falls on you to prove an exemption applies.
If you’ve been operating in Colorado without collecting or remitting sales tax, the Department of Revenue’s voluntary disclosure program limits the lookback to three years and reduces or eliminates penalties, provided you come forward before the state contacts you.16Colorado Department of Revenue. Voluntary Disclosure Program Once the agreement is in place, you register and begin collecting going forward. Waiting until an audit finds you means no lookback limit and full penalty exposure.
