Drive east on Highway 82 past the Aspen/Pitkin County Airport this year and you'll see it: graders, utility trenches, and the first vertical framing on an 11-acre site that used to hold a lumberyard, a storage facility, and eleven commercial buildings. Construction on the city's Lumberyard affordable housing project started in March 2026, and by the time Building 1 is finished in 2028 it will hold 104 of the eventual 277 deed-restricted rental units the city has been planning since 2019.
Every buyer who closes on a property inside Aspen city limits this year is funding a piece of that. Not through a special assessment or a line item they'd recognize by name. Through a tax most buyers think they already understand, and mostly don't.
The 1.5% Everyone Quotes Is Actually Two Taxes
Ask around and you'll hear the same shorthand: Aspen's transfer tax is 1.5%. That's true as a total, but it's not one tax. It's two, passed by separate ballot measures eleven years apart, funding two unrelated things, with two different expiration dates written into the code.
The first is the Wheeler Real Estate Transfer Tax, 0.5% of the sale price, approved by Aspen voters in May 1978 and first collected starting January 1, 1979. Its job is funding the Wheeler Opera House, the city's historic performance venue, along with arts programming at the Red Brick Center. Voters extended it in 2021 and it now runs through December 31, 2039.
The second is the Housing Real Estate Transfer Tax, 1.0% of the sale price, approved in 1989 and effective July 1 of that year. Its stated purpose in the municipal code is direct: addressing a housing shortage so severe that vacant land and existing buildings need to be purchased, renovated, and built on immediately. It runs through December 31, 2060, twenty-one years longer than the Wheeler tax.
Two taxes, two purposes, two sunset clocks. They just happen to land on the same closing statement as a single combined percentage, which is why almost every online guide to the Aspen RETT collapses them into one number and moves on.
Why the Split Matters at the Closing Table
Here's where the collapsing causes a real, dollar-denominated problem. The $100,000 exclusion that gets mentioned constantly in Aspen RETT explainers applies to the Housing tax only. It does not apply to the Wheeler tax.
Run the math on a $2.5 million sale. The Wheeler tax is 0.5% of the full $2.5 million, no exclusion, no adjustment: $12,500. The Housing tax is 1.0% applied after subtracting $100,000 from the price, so 1.0% of $2,400,000: $24,000. Total owed: $36,500.
Compare that to the shortcut a lot of buyers run in their head, treating the whole 1.5% as if it gets the exclusion: 1.5% of $2,400,000 comes out to $36,000. The gap is only $500 on a deal this size, small enough to round away. But the gap scales with price, and more importantly, it reveals that the two components are computed on different bases entirely. One taxes the full consideration. The other taxes the full consideration minus $100,000. Getting that backwards on a $10 million or $20 million compound produces a bigger miss, and it means the number your closing agent hands you isn't a single formula, it's two formulas added together.
What the Housing Tax Is Actually Funding Right Now
The Housing RETT doesn't disappear into a general fund. It's the financial engine behind the Aspen/Pitkin County Housing Authority's affordable housing program, and the Lumberyard is currently the largest thing that program is building.
The numbers on that project are public and specific. Gorman & Company, a Wisconsin-based developer active in Colorado since 2014, was selected as the development partner in July 2025 after a competitive process. Aspen City Council approved the ground lease and related financing agreements in March 2026, construction began that same month, and Phase A covers 104 units along with new roads, utilities, and transit infrastructure. Phase B, adding the remaining 173 units, goes back to council for approval in May 2027, with full buildout targeted for 2029. The total project cost is estimated at $360 million, funded through a mix of sources including Gorman's own capital contribution, Middle-Income Housing Tax Credits, a Colorado Department of Local Affairs grant, and city funds drawn in part from the Housing RETT.
The units will serve households earning between 50% and 240% of Area Median Income, aimed at the teachers, healthcare workers, and service employees the resort economy depends on. All of it stays permanently deed-restricted under APCHA regulations once complete.
That's a concrete answer to a question most buyers never think to ask when they see the tax line on their closing disclosure: not "why does this exist" but "where does it actually go, this year, on this street."
How Aspen's Rate Compares to the Rest of the High Country
Aspen's combined 1.5% sits in the middle of the pack among Colorado's resort towns with local transfer taxes, not at the extreme either direction.
| Town | RETT Rate |
|---|---|
| Steamboat Springs | None |
| Durango | None |
| Breckenridge | 1.0% |
| Vail | 1.0% |
| Frisco | 1.0% |
| Winter Park | 1.0% |
| Snowmass Village | 1.0% (separate town, own ordinance) |
| Aspen | 1.5% |
| Avon | 2.0% |
| Telluride | 3.0% |
| Crested Butte | 3.0% |
On a $2 million property, that spread is the difference between $20,000 in Breckenridge or Vail and $60,000 in Telluride. Aspen's roughly $29,000 on the same price point (after the housing exclusion) lands closer to the low end of that range than buyers who've heard "Aspen taxes everything" tend to assume.
Snowmass Village deserves its own note because it's easy to confuse with Aspen given the shared valley. It's a separate municipality with its own 1.0% transfer tax, and properties inside the Snowmass Base Village Metro District carry an additional 1.0% surcharge on top of that, for 2.0% total in that specific pocket. Same valley, different rate, different ordinance.
The Exemptions That Exist, and the One That Doesn't
Aspen's municipal code, Section 23.48.040, lists specific carve-outs from both taxes: transfers to government entities or charitable organizations, gifts made for love and affection with no money changing hands, transfers triggered by death, wills, or court decrees, termination of joint tenancy without added consideration, and corrective deeds that don't change actual ownership. Existing deed-restricted affordable housing units are exempt from the Housing tax specifically.
What's not on that list, despite showing up in at least one online guide circulating this year, is a blanket exemption for buyers who intend to make the property their primary residence. No version of the ordinance, the city's own summary page, or the housing authority's funding documentation supports that claim. If you're budgeting a purchase around an exemption you read about that isn't documented anywhere official, get it in writing from the city's finance department before you rely on it.
Before You Write the Offer
A few things worth confirming early, not at the closing table:
- Confirm the parcel actually sits inside Aspen city limits. Properties with an Aspen mailing address can still fall in unincorporated Pitkin County or in Snowmass Village, each with its own tax treatment, and some sit right at the boundary line where it isn't obvious from the address alone.
- Budget the two taxes separately rather than one blended percentage, especially on higher-value properties where the different bases produce a bigger gap than the rounding error on a modest sale.
- If you believe an exemption applies, start the paperwork early. The city's exemption application requires supporting documentation, such as trust instruments or court orders, submitted before the deed records, not after.
- Confirm who's paying in the purchase contract. The ordinance places responsibility on the buyer by default, but purchase agreements can and do reallocate that in negotiation.
- Don't forget the state-level pieces stacked underneath. Colorado's documentary fee runs a flat one cent per hundred dollars of price, and the county recording fee has been a standardized $43 per document statewide since July 2025. Both are trivial next to the RETT, but they're separate line items your title company will still itemize.
FAQ
Does the RETT apply if I buy land instead of a finished home? Yes. The tax applies to any real property transfer within city limits, including vacant land, condos, and commercial parcels, not just single-family homes.
Is there a minimum sale price below which the tax doesn't apply? The $100,000 exclusion reduces the taxable base for the Housing tax specifically. There's no stated minimum threshold below which the tax is waived entirely, aside from the documented exemption categories.
If I'm exempt from one RETT, am I automatically exempt from both? Not necessarily. The city's exemption application form covers both the Wheeler and Housing taxes together, but each exemption category has its own qualifying documentation, and it's possible to owe one and not the other depending on the transaction structure.
Does Pitkin County charge its own separate transfer tax outside city limits? Based on how the tax is structured, the RETT is a City of Aspen tax, not a county-wide one. Pitkin County functions as the recording authority for the deed, but properties outside the actual city boundary aren't subject to Aspen's RETT.
Aspen's transfer tax was never designed to be simple, and treating it as a single flat percentage is the fastest way to misjudge your closing costs on a high-value deal.
