Denver's short-term rental market sits at the intersection of urban demand and mountain-town tourism. The Mile High City draws visitors for professional sports, concerts at Red Rocks, craft beer culture, and — most importantly — as a gateway to Colorado's ski resorts and national parks. If you host an Airbnb, VRBO, or direct-booking rental in Denver or the surrounding Front Range, you face a unique combination of city lodger's taxes, Colorado state income tax, strict STR licensing rules, and operating costs that reflect the region's high altitude and winter climate.
Denver's Lodger's Tax (10.75%)
Denver imposes a lodger's tax of 10.75% on all short-term accommodations of fewer than 30 consecutive days. This tax applies to your total rental charge, including cleaning fees passed to guests. Airbnb and VRBO collect and remit Denver's lodger's tax on behalf of hosts for bookings made through their platforms, but you are responsible for collecting and remitting this tax on any direct bookings. Register with the Denver Department of Finance to obtain your lodger's tax license and file returns on time — late filings incur penalties and interest.
Keep in mind that lodger's tax is not your expense — you collect it from guests and pass it through to the city. It does not reduce your taxable income. However, your platform host fees, cleaning costs, and other operating expenses remain fully deductible against your rental revenue. For a complete breakdown of what you can write off, see our 2026 STR tax deductions checklist.
Colorado State Income Tax (4.4% Flat Rate)
Unlike Tennessee or Florida, Colorado imposes a state income tax on your net rental income. Colorado's flat rate of 4.4% applies to all taxable income, including STR profits. Your Colorado return generally starts with federal adjusted gross income, so the deductions you claim on your federal Schedule C or Schedule E flow directly through to your state return. Maximizing federal deductions — depreciation, operating expenses, mileage — reduces both your federal and Colorado tax bills simultaneously. For hosts operating across multiple states (for example, a Denver property and a Breckenridge cabin), Colorado requires you to allocate income to the state where the property is located. Review our Colorado statewide STR tax guide for multi-property considerations.
Denver STR License Requirements
No credit card required
Denver requires all short-term rental hosts to obtain an STR license before listing their property. The city's licensing framework includes several key requirements that directly affect how you operate and what you can deduct:
Primary residence rule. In most residential zoning districts, Denver restricts STR licenses to primary residences only. This means the property must be your primary home — the place where you live for the majority of the year. Investment properties in these zones generally cannot obtain STR licenses. Some mixed-use and commercial zones have different rules, so verify your property's zoning before purchasing an investment STR in Denver.
License and inspection. The application requires a property inspection for safety compliance (smoke detectors, carbon monoxide detectors, egress windows), proof of insurance, and payment of license fees. Licenses must be renewed annually. All license fees, inspection costs, and any code-compliance upgrades are deductible business expenses.
Responsible party requirement. Denver requires a designated responsible party who can respond to issues at the property within one hour. If you hire a co-host or property manager to fulfill this role, their fees are deductible operating expenses.
Mountain Property Considerations
Many Denver-based hosts also own STR properties in nearby mountain markets — Breckenridge, Vail, Estes Park, Winter Park, and Steamboat Springs. These mountain rentals introduce additional tax and expense considerations:
High property values and depreciation. Mountain properties in Summit County (Breckenridge, Keystone) and Eagle County (Vail, Beaver Creek) often carry purchase prices of $800,000 to well over $2 million. After subtracting land value, the depreciable basis on these properties can be substantial. A cost segregation study can accelerate depreciation deductions by reclassifying components like hot tubs, built-in entertainment systems, ski storage areas, and landscaping to shorter recovery periods — generating meaningful tax savings in the early years of ownership.
Separate local taxes. Each mountain town has its own lodging tax structure. Breckenridge, Vail, and Estes Park all impose local accommodation taxes in addition to Colorado state sales tax. Rates vary and can change annually. Track each property's tax obligations separately.
Mileage to mountain properties. Denver to Breckenridge is roughly 80 miles one way. Denver to Estes Park is about 70 miles. At the 2026 IRS standard mileage rate of $0.725 per mile, a single round trip to Breckenridge generates $116 in mileage deductions. A host making that drive twice a month for turnovers, inspections, and supply runs logs over $2,780 in annual mileage deductions. Use DeductFlow's mileage tracker to log every trip — the distance adds up fast when your rental is in the mountains.
Colorado-Specific Operating Expenses
Denver and mountain STR hosts face operating costs that differ significantly from hosts in warmer climates. These are all deductible when properly documented:
Snow removal. Professional snow plowing and shoveling services are essential for guest safety and access, especially at mountain properties. Seasonal contracts with snow removal companies, ice melt supplies, and snow blower purchases or maintenance are deductible. For mountain properties, snow removal can run $2,000-5,000+ per winter season.
Furnace and heating costs. Colorado winters demand reliable heating systems. Annual furnace inspections, filter replacements, boiler maintenance, and emergency HVAC repairs are deductible operating expenses. Utility costs for heating during guest stays (and between stays to prevent pipe freezing) are deductible based on the rental-use percentage of the property.
Altitude-related maintenance. Denver sits at 5,280 feet; mountain properties range from 7,500 to over 10,000 feet. High altitude accelerates UV degradation on exterior surfaces, dries out wood decking and siding, and increases wear on roofing materials. Exterior staining, deck maintenance, roof repairs, and UV-protective window treatments are deductible maintenance expenses that recur more frequently than at lower elevations.
Winterization and pipe protection. For properties that sit vacant between bookings during cold months, pipe insulation, heat tape, smart thermostat systems, and freeze-prevention monitoring subscriptions are deductible expenses that protect your investment and prevent costly water damage.
Ski Season vs. Summer Seasonality
Denver-area STR revenue follows a strong dual-season pattern. Ski season (December through early April) drives peak nightly rates at mountain properties, while Denver itself sees strong summer demand (June through September) from tourists visiting Rocky Mountain National Park, attending Red Rocks concerts, and exploring the city. Shoulder seasons — October/November and April/May — typically see lower occupancy and rates.
This seasonality matters for tax planning. If you materially participate in managing your STR, losses generated during low-occupancy months (combined with depreciation) may offset W-2 or other active income. Track your hours carefully — guest communication, pricing adjustments, coordinating cleaners, supply runs, and property inspections all count toward the 100-hour material participation threshold.
Finding a Denver Short-Term Rental CPA
Denver has a solid community of CPAs experienced with short-term rental taxation. When interviewing accountants, ask about their familiarity with Denver's lodger's tax, Colorado's state income tax treatment of rental income, cost segregation for high-value mountain properties, and Schedule C vs. Schedule E filing strategies. A CPA who understands both Denver's local regulations and federal STR tax strategies will identify deductions that a generalist might miss.
Regardless of which CPA you work with, organized records are what separate hosts who overpay from those who pay the legal minimum. Every expense categorized, every mile logged, every active hour documented. That is exactly what DeductFlow is built for.
