Colorado Rental Property Taxes: What Investors Actually Pay in 2026
Program and regulatory figures verified July 24, 2026. Details change; confirm your scenario with us.
Colorado is a low-property-tax state, which quietly helps every DSCR ratio here. Two things can change the picture on a specific parcel: the metro-district mill levy, and the assessment figures that shift with each odd-year reappraisal. We model the real parcel.
Why Colorado's effective rate is so low
Colorado's all-in effective property tax lands around 0.5% of market value, roughly a quarter of what Texas metros charge and among the lowest rates in the country. The reason is the assessment math. Colorado doesn't tax your full market value; SB24-233 sets a residential assessment rate of 6.7–6.8% for non-school local levies (7.15% for the school-district portion) and applies it only after an exemption. That low rate, applied to a reduced value, sits inside PITIA and leaves more rent for your DSCR ratio than almost any other state.
How the 2026 exemption works (the $700,000 vs $70,000 confusion)
People trip over two numbers here, so here they are together. SB24-233 exempts 10% of the first $700,000 of a home's actual value before the assessment rate applies. Ten percent of $700,000 is $70,000, so on a home worth $700,000 or more, the exemption removes up to $70,000 from the taxable value. Both figures describe the same mechanism: $700,000 is the value base the 10% is measured against, and $70,000 is the maximum dollar reduction that produces. The $700,000 figure floats with inflation in future years. Apply the exemption first, then the 6.7–6.8% assessment rate, and you land near that 0.5% effective figure. It works the same whether the property is owner-occupied or a rental.
The two-year cycle, and no reassessment on sale
Here's a corrective that matters to buyers coming from California or other acquisition-based states: Colorado does not reassess your property to market value just because you bought it. Colorado reappraises all property on a two-year cycle, in odd-numbered years, using a valuation study of comparable sales across the whole area, not your purchase price. So buying a Colorado rental doesn't reset its assessment to what you paid, the way it would under a Proposition 13-style system. Your first bill reflects the county's current cycle value, and it adjusts at the next odd-year reappraisal along with everyone else's. That predictability is friendly to underwriting.
The metro-district mill trap
The one place a Colorado tax bill balloons is a metro district. Newer subdivisions, especially in Aurora, Commerce City, and the far Front Range suburbs, fund their infrastructure through a special taxing district that layers extra mills on top of the county and school levy. Each mill is one dollar of tax per thousand dollars of assessed value, and a metro district can add 30 to 50 mills, enough to roughly double the property-tax bill versus an identical home in an established neighborhood. Because that tax sits inside PITIA, it can flip a ratio from clearing to failing. Two adjacent subdivisions can carry very different bills. We pull the actual mill levy for the parcel before you offer, and it's the number national lenders miss.
Income tax, insurance, and the hail factor
Two more lines belong in a Colorado rental model. Rental income is taxed at Colorado's flat 4.40% state rate (2026), on top of federal tax; your CPA runs that. And insurance is a rising cost here: hail across the Front Range "hail alley" is the number-one driver of homeowners premiums and can be a large share of the bill, while wildfire exposure pushes some mountain and foothill properties toward the Colorado FAIR Plan, the insurer of last resort, which caps dwelling coverage at $750,000 on an actual-cash-value, fire-only basis after three carrier declinations. Insurance sits inside PITIA too, so we quote it early. Portfolio-wide tax strategy belongs to your CPA; the financing consequences belong to us: scaling guide.

Frequently asked questions
How much are property taxes on a Colorado rental?
Roughly 0.5% of market value effective, among the lowest in the country. SB24-233 applies a 6.7–6.8% non-school assessment rate (7.15% school) to a reduced value after exempting 10% of the first $700,000. A metro district can add 30 to 50 mills that roughly doubles the bill in newer subdivisions, so the parcel matters.
How does Colorado's 2026 property tax exemption work for a rental?
SB24-233 exempts 10% of the first $700,000 of a home's value (up to $70,000 off taxable value) before applying the 6.7–6.8% non-school assessment rate (7.15% for the school portion). The $700,000 is the base the 10% is measured against; $70,000 is the maximum reduction. It works the same whether the property is owner-occupied or a rental.
Does buying a rental reset its property taxes in Colorado?
No. Colorado reappraises on a two-year cycle in odd-numbered years using area-wide comparable sales, and it does not reassess a property to your purchase price simply because it sold. Unlike a Proposition 13-style system, buying doesn't reset the assessment, which makes the tax line more predictable for underwriting.
What is a metro district and how does it affect my taxes?
A metro district is a special taxing entity that funds a newer subdivision's infrastructure through extra mills on top of the county and school levy. It can add 30 to 50 mills, roughly doubling the property-tax bill versus an established neighborhood. Because the tax sits inside PITIA, it directly affects your DSCR ratio, so we pull the parcel's actual mill levy before you offer.
