Colorado Property Tax Update
Colorado property taxes are spiking in 2026 — with some homeowners facing 30%–40% increases. The causes are layered: the end of relief programs, rising home values, higher assessment rates, and the absence of caps like the Gallagher Amendment. While this creates real hardship for many — especially seniors and working-class families — there are steps you can take to protect yourself: appeal your assessment, apply for exemptions, and stay informed about your options. The truth is, unless new legislation puts limits back in place, property taxes in Colorado may continue to rise. Planning ahead and using the tools available to you is the best way to stay afloat in this shifting landscape.

Why Are Colorado Property Taxes Increasing So Rapidly?
Let’s unpack what’s really behind the big tax jumps this year.
1. Home Values Have Skyrocketed
It all starts with how property taxes are calculated in Colorado: the assessed value of your home × the assessment rate × the mill levy.
When the housing market’s hot — like it has been the past few years — your home’s market value climbs, and so does your assessed value, which is the number the tax man uses to figure out your bill.
Example:
If your home was worth $400,000 in 2021 and now it’s worth $560,000 (a 40% increase), your taxes are going to reflect that — unless something else offsets the jump. In most counties, nothing is offsetting it in 2026.
Data from the Colorado Association of Realtors confirms that some Front Range communities saw double-digit home value increases during the last assessment cycle.
2. Temporary Relief Measures Have Expired
In 2022 and 2023, the state government gave homeowners some temporary relief in the form of:
- $15,000–$40,000 cuts to their assessed value
- Reduced assessment rates
These breaks helped slow the increase in taxes — but they were never permanent. In 2026, they’re gone, and bills are back to being based on full, unadjusted property values.
Delta County and other county assessors have already confirmed the rollback of discounts, meaning residents will see higher bills — even if their mill levy didn’t increase.
3. Assessment Rates Are Back Up
Colorado’s residential assessment rate (the percentage of your home’s value that is taxable) went from:
- 6.765% in 2023
- to 7.15% in 2026
This is a nearly 6% increase in what part of your property is taxable — which, combined with higher home values, leads to much higher tax bills.
4. Repeal of the Gallagher Amendment
The now-defunct Gallagher Amendment, repealed by voters in 2020, used to put a hard cap on how much residential property tax could grow relative to commercial property tax.
With Gallagher gone, there’s no longer a ceiling on how much your taxes can rise as home values increase. This is a key reason why taxes have jumped so aggressively, and it’s unlikely they’ll be re-capped any time soon.
5. Local Mill Levies Are Still in Play
A mill levy is the rate used to calculate local taxes. Counties, school districts, fire departments, and libraries all fund their services with these levies. Even if a mill rate doesn’t increase, the amount of revenue it brings in increases when property values rise.
Because many of these levies were voter-approved and don’t adjust downward, the result is a bigger tax bill — even if nothing changed locally.
Breaking Down a Real-Life Example of Colorado Property Tax Update
Here’s how a typical tax bill looks before and after the 2026 change:
| Year | Market Value | Assessment Rate | Taxable Value | Mill Levy | Annual Taxes |
|---|---|---|---|---|---|
| 2023 | $450,000 | 6.765% | $30,442 | 80 mills | $2,435 |
| 2026 | $630,000 | 7.15% | $45,045 | 80 mills | $3,603 |
Increase: $1,168 (≈ 48%)
That’s a monthly increase of about $97. For many households, that could make or break a budget.
Who’s Hit the Hardest by Colorado Property Tax Update?
Seniors and Retirees
Folks on fixed incomes, especially older adults, are feeling the squeeze. Their income doesn’t increase with inflation — but their property taxes sure do. That creates a serious imbalance.
According to The Colorado Sun, many older homeowners are being forced to consider downsizing or even selling their long-time homes due to rising costs.
Working-Class Families and First-Time Buyers
Younger families who stretched to buy their first homes are now slammed with higher bills than expected. Many didn’t budget for such sharp increases in taxes and are now struggling to adjust.
Landlords and Renters
Landlords facing tax increases often pass the cost down to renters, creating a ripple effect across the housing market. It’s one more reason rents in Colorado have continued to rise — even in suburban areas.
What Happened to Proposition HH?
In 2023, Proposition HH was pitched as a fix. It would’ve:
- Capped property tax increases at a lower rate
- Expanded exemptions for seniors and low-income homeowners
- Used state TABOR refunds to backfill local funding losses
But voters rejected the measure, partly due to concerns about losing TABOR refund checks and fears that it gave too much power to the state.
Without HH, homeowners are left with little protection against future hikes — unless lawmakers return to the drawing board.
What Can You Do About Colorado Property Tax Update?
1. File an Appeal
If you think your property value is inflated, you can appeal. You’ll need:
- Recent comparable home sales
- Photographs or documentation showing property damage or devaluation
- A formal appeal letter
Deadline to appeal: Usually end of June in most counties.
2. Apply for Senior or Veteran Exemptions
If you’re 65+ and have lived in your home for 10+ years, you may be eligible for the Senior Property Tax Exemption:
- 50% exemption on the first $200,000 of value
- Must apply through your county
Veterans with a service-connected disability rating of 100% may also qualify.6
3. Consider a Deferral Program
Some counties allow homeowners (especially seniors) to defer part of their tax bill. This is not forgiveness — it works like a lien and is repaid when the home is sold — but it can provide short-term relief.
Contact your county treasurer for options.
4. Talk to Your Mortgage Company
If your taxes are paid through escrow, your monthly mortgage payment will increase. Be proactive: contact your lender and ask how your escrow account is being adjusted — don’t get caught by surprise.
