🇯🇵 この記事は日本語でもお読みいただけます日本語版はこちら

If you just opened your 2026 property tax bill and felt your stomach drop, you’re not alone. Homeowners across Colorado are seeing increases of 20% to over 40% compared to last year. That’s a real hit to the household budget, and it’s catching a lot of people off guard.

Let me break down what’s happening, why your bill went up so much, and what you can actually do about it.

Why Did Colorado Property Taxes Jump So Much?

Here’s the short version: the temporary tax relief that was put in place over the past couple of years is expiring. During 2023 and 2024, Colorado lawmakers passed measures that temporarily lowered assessment rates and provided value deductions to offset the rapid rise in home values. Those buffers are now going away.

For 2026, the residential assessment rate for schools is climbing to 7.05%, while the rate for other local government districts is set at 6.25%. There is a 10% value exclusion capped at $70,000 for the local government portion, which brings the effective rate down to roughly 6.4% for an average-valued home. But even with that deduction, the net effect is a significant increase over what you paid last year.

Think of it this way: your home’s assessed value might not have changed much, but the rate applied to that value just got a lot higher. That’s why the bill feels so different.

How Much More Will You Actually Pay?

It depends on your county and your home’s value, but the typical increase across the Denver metro area falls between 20% and 40%. For a home valued at $600,000 in Douglas County, that could mean an extra $1,200 to $2,400 per year. In Arapahoe County, where mill levies vary by district, some homeowners are seeing even steeper jumps.

The areas hit hardest tend to be those where home values appreciated the most during 2021 and 2022. If your home saw big gains during the pandemic market frenzy, those higher values are now being taxed at higher rates without the temporary cushions.

Can You Appeal Your Property Tax Assessment?

Yes, and I strongly encourage you to look into it. Colorado gives homeowners the right to protest their property valuation with the county assessor’s office. The appeal window typically opens on May 1 and closes on June 1. You’ll want to mark those dates on your calendar.

Here’s what a successful appeal usually looks like:

Gather comparable sales. Pull 3 to 5 recent sales of similar homes in your neighborhood. If those homes sold for less than the assessed value on your property, you have a solid case. I help my clients with this kind of market data all the time, so feel free to reach out if you need comps.

Document any condition issues. If your home has deferred maintenance, an older roof, or other factors that would reduce its market value compared to the assessed value, photograph and document everything.

File on time. Late appeals are almost never accepted. Don’t wait until the last week of May.

If the county assessor denies your appeal, you can escalate to the county Board of Equalization and even the state Board of Assessment Appeals. Most homeowners don’t need to go that far, but it’s good to know the option exists.

Relief Programs You Should Know About

Colorado offers several programs that can help offset the sting:

Property Tax Deferral Program. The state treasurer offers a low-interest loan program that allows qualifying homeowners to defer their property tax payments. You still owe the taxes, but you can push the payment out over time. This can be a lifeline for retirees or homeowners on fixed incomes.

Senior and Veteran Exemptions. If you’re 65 or older and have lived in your home for at least 10 years, you may qualify for the Senior Homestead Exemption, which exempts 50% of the first $200,000 of your home’s value. Veterans with qualifying disabilities have similar exemptions available.

Property Tax/Rent/Heat Credit (PTC Rebate). Lower-income homeowners and renters can apply for this rebate through the Colorado Department of Revenue. The income thresholds are modest, but it’s worth checking if you qualify.

What This Means If You’re Thinking About Selling

Rising property taxes are one more factor pushing some homeowners to reconsider whether their current home still makes financial sense. If you’re in a larger home and your kids have moved out, downsizing could save you thousands per year in property taxes alone, not to mention insurance and maintenance.

I’ve been working with several clients in Parker and Castle Pines who decided to sell specifically because their property tax bills made their carrying costs unsustainable. Moving to a smaller home or a different tax district can make a huge difference.

What This Means If You’re Buying

Buyers, don’t forget to factor property taxes into your monthly budget when you’re shopping for homes. A lot of online mortgage calculators use outdated tax estimates. Ask your lender to use the 2026 tax rate, not last year’s number, when calculating your monthly payment.

Also pay attention to which tax district a home sits in. Two homes with the same price tag in the same zip code can have very different property tax bills depending on their specific taxing district, school district, and special district overlays.

The Bottom Line

Nobody likes paying more in property taxes. But understanding why your bill changed and knowing your options puts you in a much better position. Review your assessment, consider an appeal if the numbers don’t add up, and look into any relief programs you might qualify for.

If you want to talk through how property taxes affect your specific situation, whether you’re considering selling, buying, or just trying to budget for the year, I’m always happy to help.
