Property taxes don't disappear when you retire. For many Colorado seniors, they keep climbing even on a fixed income. According to Ownwell's 2025 National Homeowner Survey, 85% of Colorado homeowners worry about significant increases in their annual property tax bills.
The Colorado Senior Property Tax Exemption, also called the Senior Homestead Exemption, can cut your taxable value by up to $100,000. But it is not the only tool available to you.
Below, you will find who qualifies, how to apply, how much you can save, and how pairing the exemption with a property tax appeal can stretch your savings even further.
Key Takeaways
The Senior Homestead Exemption can reduce your taxable value by up to $100,000.
You must be 65 or older and have owned a primary residence for 10 or more consecutive years.
File with your county assessor by July 15; the exemption auto-renews once approved.
Colorado also offers programs for recent movers and tax deferral.
You can stack the exemption with a property tax appeal for additional savings.
How Colorado's Senior Property Tax Exemption Works
Colorado's Senior Homestead Exemption, originally passed as Referendum A in 2000, exempts 50% of the first $200,000 of a property's actual value from property taxation. In practice, that means the maximum exemption removes $100,000 from the actual value used to calculate your tax bill.
The exemption applies only to your owner-occupied primary residence. Colorado defines primary residence as the address where you are registered to vote. Only one exemption is allowed per property per tax year, even if both you and your spouse meet the eligibility requirements.
When the state budget allows, Colorado reimburses local governments for the revenue lost to this exemption. That means the program does not reduce funding for local schools or services. Instead, the state absorbs the cost on behalf of qualifying seniors.
For homeowners across the Front Range, where Colorado property values have climbed sharply in recent reassessment cycles, this exemption can reduce your annual tax bill by hundreds of dollars. A home valued at $500,000 could see its taxable actual value drop to $400,000, translating to roughly $536 in annual savings at a typical Denver-area mill levy.
Who Qualifies for the Colorado Senior Property Tax Exemption
You must meet all of the following criteria as of January 1 of the application year. The details matter.
Basic requirements:
Age: You must be at least 65 years old on January 1 of the year you apply.
Ownership: You or your spouse must be the owner of record for 10 or more consecutive years prior to January 1.
Occupancy: You must have used the property as your primary residence for those same 10 or more consecutive years.
Surviving Spouse Eligibility
If your spouse qualified for the exemption and has since passed away, you may still be eligible. You must have been legally married to a qualifying senior on January 1 of any year since 2002, must not have remarried, and must still occupy the same property.
Exceptions to the Ownership and Occupancy Rules
Colorado recognizes several exceptions that can preserve your eligibility:
Your home is held in a trust for estate planning purposes, and the maker of the trust is the qualifying senior or their spouse.
You are confined to a hospital, nursing home, or assisted living facility.
Your prior home was condemned through eminent domain.
Your prior home was destroyed by a natural disaster.
Married couples who own multiple properties may claim the exemption on only one. Attempting to claim on more than one property, or providing false information, triggers penalties under Colorado law.
If you are 65 or older and have lived in your home for a decade or more, check your eligibility with your county assessor.
How to Apply for the Colorado Senior Property Tax Exemption
Filing for the exemption is free, and the process is handled entirely through your county assessor's office. Here is how to apply in four steps.
Determine which form you need: Colorado offers two application forms.
The Short Form covers applicants who meet the basic age, ownership, and occupancy requirements.
The Long Form is for surviving spouses and applicants qualifying under one of the exceptions listed above.
Both forms are available from your county assessor or through the Colorado Division of Property Taxation (DPT) website.
Complete the application: Fill in your property information, ownership dates, and residency details. Have your property's schedule number handy; you can find it on your most recent tax statement.
Submit to your county assessor by July 15: File the completed form with the assessor's office in the county where your property is located. Late applications are accepted through August 15, but filing late means you forfeit your right to appeal if the application is denied.
Confirm approval and enjoy auto-renewal. Once your county assessor approves the exemption, it remains in effect until a disqualifying event occurs. You do not need to reapply each year. However, you must report any changes in ownership or occupancy to the assessor within 60 days.
The July 15 deadline is firm for full filing rights. If you miss it, you can still submit through August 15, but without the safety net of an appeal if your application is denied. Mark your calendar now.

How Much Can You Save? A Colorado Senior Exemption Worked Example
The actual dollar savings depend on your home's value and your local mill levy. Here is a worked example using a $500,000 Denver-area home.
Colorado's residential tax rate is approximately 6.7%. The typical Denver-area mill levy is roughly 80 mills. The Senior Homestead Exemption removes $100,000 from your taxable actual value (50% of the first $200,000).
Line Item | Without Exemption | With Exemption |
|---|---|---|
Actual value | $500,000 | $500,000 |
Exemption reduction | $0 | -$100,000 |
Taxable actual value | $500,000 | $400,000 |
Assessed value (6.7%) | $33,500 | $26,800 |
Mill levy (80 mills) | 0.080 | 0.080 |
Annual property tax bill | $2,680 | $2,144 |
Annual savings | $536 |
For a $500,000 home, the exemption saves you approximately $536 per year. For seniors on fixed incomes, even a $536 annual reduction can cover a month of groceries or two utility bills. Over a 10-year period, that totals $5,360 in cumulative savings (assuming the assessed value, millage, and tax rate stay the same).
What if your home is worth more? The exemption caps the actual value reduction at $100,000, regardless of your home's total value. A $700,000 home receives the same $100,000 reduction as a $500,000 home. The savings scale with your mill levy, not your home value above the $200,000 threshold.
But what if your home's assessed value is also too high? The exemption reduces your taxable value. A property tax appeal reduces your assessed value. You can do both, and stacking the two strategies can multiply your savings.
Other Colorado Property Tax Relief Programs for Seniors
The Senior Homestead Exemption is not the only available relief program. Colorado offers additional programs that serve different situations. Understanding your options helps you choose the right path or combine them.
Program | What It Does | Eligibility | Deadline | Key Difference |
|---|---|---|---|---|
Senior Homestead Exemption | Reduces taxable actual value by 50% of the first $200,000 (up to $100,000 reduction) | Age 65+, 10-year ownership/occupancy of primary residence | July 15 | Best for long-term homeowners |
Qualified Senior Primary Residence Classification | Same 50% reduction on a new primary residence | Age 65+, moved on or after Jan. 1, 2020, previously qualified for or would have qualified for the exemption | March 15 | For seniors who recently moved |
Senior Property Tax Deferral Program | Defer all or part of property taxes; repaid when the home is sold | Age 65+, meet income/equity requirements (hold at least 25$ equity in the property) | April 1 | Cash-flow relief, not a reduction |
Qualified Senior Primary Residence Classification
This newer program closes an eligibility gap. If you moved to a new home on or after January 1, 2020, you lost your Senior Homestead Exemption because the 10-year ownership clock restarted. The Qualified Senior Classification lets you carry the same 50% reduction to your new primary residence.
The deadline is March 15, earlier than the July 15 exemption deadline. If you moved recently and have not filed, check your eligibility with your county assessor immediately.
Senior Property Tax Deferral Program
If you need cash-flow relief rather than a permanent reduction, Colorado's deferral program lets you postpone all or part of your property tax payments. The deferred amount accrues interest at 4.238% in 2026 and must be repaid when the home is sold or ownership transfers.
This program is separate from the exemption. You can claim both the exemption and deferral at the same time.
The Property Tax/Rent/Heat Credit (PTC Rebate) is an additional income-based program administered by the Colorado Department of Revenue. We do not cover it in detail here, but it may provide further relief for low-income seniors.

How Ownwell Can Help With Your Colorado Property Taxes
The Senior Homestead Exemption reduces your taxable value. But if your county assessor overvalued your home in the first place, you are still paying more than you should on the portion of value that the exemption does not cover. That is where a property tax appeal comes in.
Ownwell does not file exemptions in Colorado. Ownwell does handle your property tax appeal from start to finish: building a comparative market analysis, filing the appeal with the County Board of Equalization (CBOE), representing you at hearings, and tracking the result.
You can claim the Senior Homestead Exemption and file an appeal in the same year. The exemption lowers your taxable value. The appeal lowers your assessed value. Together, they target different parts of your tax bill, and the combined savings can exceed what either strategy delivers alone.
Ownwell charges a 35% contingency fee in Colorado. There is no upfront cost. You pay only if your appeal results in savings. Across more than 1 million appeals processed, 88% of customers have achieved a reduction.
If you are a Colorado senior looking to reduce your tax bill beyond what the exemption provides, start your Colorado property tax appeal with Ownwell.

Frequently Asked Questions
Do I Qualify for the Colorado Senior Property Tax Exemption?
You qualify if you are at least 65 years old on January 1, have owned and occupied your home as a primary residence for 10 or more consecutive years, and the property is where you are registered to vote. Surviving spouses of qualifying seniors may also be eligible.
How Much Does the Colorado Senior Property Tax Exemption Save?
Savings depend on your local mill levy. For a $500,000 Denver-area home with an 80-mill levy, the exemption saves approximately $536 per year. Higher mill levies produce larger savings.
Is the Colorado Senior Property Tax Exemption Currently Suspended?
The exemption is active for 2026. In prior years, state budget constraints have occasionally led to partial or full suspension of reimbursements to local governments. Check the Colorado Division of Property Taxation for the latest status.
Can I Appeal My Property Taxes and Claim the Senior Exemption?
Yes. The exemption and an appeal target different parts of your tax bill. The exemption reduces your taxable actual value. An appeal challenges the county's valuation of your home. You can pursue both in the same year to maximize your Colorado property tax savings.
What Happens if I Miss the July 15 Deadline?
Late applications are accepted through August 15, but you forfeit the right to appeal a denial. For the Qualified Senior Primary Residence Classification, the deadline is March 15 with no late filing window.
