Selling Your Investment Real Estate in Colorado — Defer the Capital Gain
If you're selling a real estate in Colorado, the tax math depends heavily on your state's capital-gains treatment. Colorado's top LTCG rate is 4.4% — combined with federal 23.8% (20% LTCG + 3.8% NIIT), a lump-sum sale gives back 28.2% of your gain in year one. IRC §453 structured installment sale spreads the gain across the payment schedule, keeping you in lower brackets each year.

This page covers the real estate sale in Colorado specifically. For the general framework see the real estate guide or the §453 SIS basics.
The math — $4M sale, 20-year hold, Colorado resident
The §453 spread captures roughly the difference between these two numbers — typically 8-12 percentage points of the gain depending on your specific deal economics and Colorado's bracket structure.
Colorado-specific tax wrinkle
Colorado's flat 4.4% rate is moderate. §453 still meaningful for high-gain sales above NIIT threshold.
The Colorado real estate market
Colorado commercial real estate is concentrated in Front Range (Denver, Boulder, Ft Collins, Colorado Springs) + mountain communities (Aspen, Vail, Steamboat). 4.4% flat state tax. §1031 + §453 boot combo is common in CO property transactions.
Colorado buyers and consolidators
The active acquirers buying real estates in Colorado: Institutional REITs, family offices, 1031 buyers (avoid if you're exiting RE entirely). These institutional buyers' M&A counsel are familiar with the §453 mechanic — papering the assignment at closing is standard.
Real Estate-specific §453 wrinkle (applies in every state)
1031 fully defers if you're staying in RE. §453 is the alternative when you want OUT of the asset class. §1250 unrecaptured depreciation spreads; §1245 on personal property doesn't.
When this fits a Colorado seller
- $1.5M+ sale price (carrier minimums on the §453-deferred portion)
- Long hold with meaningful gain (where Colorado's 4.4% state rate stacks on federal)
- Sophisticated buyer whose counsel will paper the §453 assignment
- Colorado resident at closing (state residency matters for the state-tax piece)

Frequently asked
Q: I'm a Colorado resident but the property is in another state. Where's the tax? A: Generally the gain is sourced to where the property sits (real estate) or where the seller resides (intangibles). Talk to your CPA on multi-state allocation; §453 mechanic works the same.
Q: I'm planning to move out of Colorado before closing. Does that change anything? A: Maybe. Colorado's residency tests differ — California's exit tests are aggressive; other states less so. Talk to a state-tax specialist before timing the move.
Q: Does the §453 mechanic differ state-to-state? A: No. §453 is federal. State tax rates determine the size of the savings; the mechanic is identical.
