Taxes in Aspen
Aspen's tax picture combines Colorado's genuinely low statewide property tax rate and moderate flat income tax with a real, high local sales tax layer unique to Aspen's multi-district municipal funding structure -- a combination worth understanding as a whole rather than picking one favorable number.

Learn moreColorado's flat 4.40% state income tax, restated with its real TABOR variability
Colorado taxes individual income at a flat 4.40% rate for tax year 2026, though this is not fully fixed: a TABOR-driven refund mechanism can temporarily lower it in years the state certifies a qualifying revenue surplus (it dropped to 4.25% for tax year 2024; it did not trigger for 2025) -- see colorado.js for the full mechanism.
A genuinely low property tax RATE, but a real, large dollar BILL on an expensive Aspen home
Colorado's statewide effective property tax rate is approximately 0.50% (Tax Foundation, 2026) -- among the lowest in the nation. No Aspen-specific effective rate was independently verified this pass, but given the RATE applies against Aspen's genuinely high assessed values, the resulting dollar bill on a multi-million-dollar property remains substantial even at a low rate -- a distinction worth surfacing directly rather than letting 'Colorado has low property taxes' imply a small bill in absolute terms.
A high, multi-layered local sales tax funding real, specific city services
Aspen's 10.35% combined in-city sales tax (2026) breaks down precisely: 2.90% state, 3.60% Pitkin County, 2.70% City of Aspen, 0.40% Roaring Fork Transit Authority, 0.50% Aspen Fire Protection District, and 0.25% Confluence Early Childhood Development Service district. Each add-on funds a specific, real local service rather than being generic 'local tax' -- Snowmass Village a short drive away carries a notably lower 7.15% combined rate, illustrating how much this varies by exact address even within Pitkin County.
Colorado's real retirement-income tax advantages apply here too
Starting with tax year 2026, Colorado removed the dollar cap entirely on its pension/annuity income subtraction (previously $20,000 for ages 55-64, $24,000 for 65+) -- qualifying retirees can now subtract their FULL pension/annuity income with no ceiling. Social Security is fully exempt for filers 65+, and exempt for filers 55-64 with AGI under $75,000 (single) or $95,000 (joint); a Social Security subtraction and a pension subtraction share the same allowance rather than stacking. See retiring for the fuller picture.
Key takeaways
- Colorado's flat state income tax is 4.40% for 2026, subject to a TABOR mechanism that can temporarily lower it further in state-revenue-surplus years.
- Colorado's ~0.50% statewide effective property tax rate is genuinely low, but still produces a substantial dollar bill on Aspen's high assessed home values -- budget the actual figure, not just the rate.
- Aspen's combined sales tax is a high 10.35% within city limits (2026), itemized across state, county, city, transit, fire, and early-childhood-service layers -- Snowmass Village nearby runs a notably lower 7.15%.
- Starting tax year 2026, Colorado removed the dollar cap on its pension/annuity subtraction entirely, and Social Security is fully exempt for filers 65+ (and for 55-64 under an AGI threshold) -- real, current retirement tax advantages.
