Arapahoe County Tax Rates and Mill Levy Schedule

Arapahoe County sits in the Denver metro area, with Littleton as the county seat and major population centers in Aurora, Centennial, and parts of Denver. The current effective property tax rate across the county runs near 0.70% of a home’s market value. A median home valued at $387,300 produces a typical tax bill close to $2,536 each year.

Mill levies vary by tax district, school district, and any metro districts that overlap a parcel. The total mill levy combines the county, city, school, and special district amounts into a single figure.

The Board of County Commissioners certifies each year’s levies through the official Certification of Levies and Revenues document. That file shows the exact mill amount set by every district and is the source of truth for any dispute or verification request.

How Property Values Are Assessed

The Assessor discovers, lists, classifies, and values every parcel in the county. Real property is appraised at market value using sales of similar homes in the same neighborhood from a data window defined by state law. Personal property, including business equipment, is valued separately and reported on a personal property schedule each year.

• Residential property uses the sales comparison approach.
• Commercial property may use the income approach or cost approach.
• Agricultural land receives a special valuation based on productivity.
• Vacant land is valued as if it were ready for its highest permitted use.

The state legislature sets the assessment rate that turns appraised value into assessed value. Multiplied together, the appraised value, the assessment rate, and the local mill levy produce the final tax owed. Reviewing the math each year helps owners catch errors before bills go out.

Notice of Value and Assessment Explanation

On May 1, the Assessor’s Office mails a Notice of Value to every property owner. The notice lists the new total value, the classification, and the prior year’s value for comparison. Owners should read each line carefully because the notice is also the starting gun for the appeal window.

1. Check the owner name and parcel number for accuracy.
2. Compare the new value to recent sale prices in your neighborhood.
3. Review the property record card for errors in square footage, age, or features.
4. Note the appeal deadline printed on the form.

If the value looks high or the property facts are wrong, the owner can file an appeal before the printed deadline. The form and rules live on the Assessor’s Office page linked from the county website. Missing the deadline usually removes the right to challenge the value for that tax year.

Arapahoe County Property Tax Payment Deadlines

The County Treasurer sends out tax statements at the start of the collection year. The postcard statement is the only bill a property owner receives, so keeping a current mailing address with the Assessor is a smart move. Payments are split into two equal halves by default, but owners can pay the full amount in one go.

Late payments draw interest and fees under state law. Check the Treasurer’s website for the exact current-year dates before mailing a check, since Colorado statutes can shift deadlines when a date falls on a weekend or holiday.

Accepted Payment Methods

The Treasurer accepts several payment types to fit different owner needs. Picking the right method helps avoid processing delays and keeps payment tracking simple.

• Online payment by e-check or credit card through the Treasurer’s portal.
• Payment by mail using the coupon attached to the statement.
• In-person payment at the Treasurer’s office window.
• Phone payment with a service fee using the automated system.
• Automatic bank draft for owners who prefer a set-and-forget plan.

Each method posts to the tax account on a different timeline. Online and in-person payments clear fastest, while mailed checks can take several business days to apply. Saving the confirmation number after any payment protects the owner if a question comes up later.

Available Tax Exemptions and Deduction Options

Arapahoe County participates in several state-level property tax relief programs that lower the bill for qualifying owners. The Assessor administers the applications, and the Treasurer applies the credit once the exemption is approved.

Applications for the senior and veteran programs have specific file deadlines each year. Missing the window can cost a full year of relief, so owners should file as soon as they know they qualify. The Colorado Division of Property Taxation publishes the income limits and forms on its website for reference.

Senior Citizen and Veteran Relief

Two relief programs carry the most weight for fixed-income residents. The senior exemption reduces the amount of value taxed for qualifying owners age 65 and older. The veteran exemption applies a similar reduction for veterans with a service-connected disability, and the two programs can stack in some cases.

• Verify age or disability status before applying.
• Confirm income against the current state limit.
• Submit the form to the Assessor before the printed deadline.
• Keep a copy of the approval letter with tax records.

Colorado’s Property Tax Administrator also runs a short-term refund program for applicants who experience a sudden hardship. Owners facing a medical crisis or a natural disaster can ask the Assessor about the hardship refund form. The program is narrow, but it offers real cash back when a serious event pushes a household past the income cap.

How to Dispute an Arapahoe Property Tax Assessment

An appeal challenges the value, classification, or both. The protest starts with the County Assessor, and if the owner remains unsatisfied, the case can move to the Board of Equalization and then to district court. Each stage carries its own paperwork and its own deadline, so tracking dates closely is critical.

1. File a protest with the Assessor on or before the deadline printed on the Notice of Value.
2. Include evidence such as a recent appraisal, comparable sales, or photos of property defects.
3. Attend the informal hearing held by the Assessor’s Office if offered.
4. If denied, escalate to the Board of Equalization within the window allowed by statute.
5. Take the case to the Colorado Judicial Branch as a final option under §39-8-106 to §39-8-108 C.R.S.

Strong evidence wins appeals. Pulling at least three comparable sales that closed near the assessment date, plus any photos of damage or needed repairs, builds a clear case. The Colorado Judicial Branch website explains the forms needed to file a property tax appeal in district court.

Commercial Property Tax Guidelines

Commercial parcels follow a separate valuation path. The Assessor may use an income approach that turns rent rolls and expense data into value, or a cost approach that adds land value to replacement cost. Personal property inside the building, from office furniture to manufacturing equipment, is reported on a separate schedule and billed as personal property tax.

• File the Declaration of Personal Property by the printed deadline each year.
• Track additions and removals of equipment so the schedule stays current.
• Report any business closure or sale to stop billing right away.
• Keep income and expense records for at least three years in case of an audit.

Missing the personal property filing can lead to a value assigned by the Assessor, which often runs higher than a true declaration. Penalties can apply for late or missing declarations, so owners should treat the deadline like a tax deadline.

Rental Property Tax Considerations

Rental properties are valued using the income approach because rent data is the strongest value signal. A higher rent roll generally means a higher assessment, and a high vacancy rate can pull value down. The owner reports rent and expense data on a property record card, and the Assessor reviews the data during the standard reappraisal cycle.

• Document actual rent rolls, not asking rent, each year.
• Track vacancy rates and turnover costs.
• Report capital improvements that boost the income potential.
• Keep service contracts and major repair receipts on file.

The sales data window used for residential valuation also applies to commercial rentals, so a recent sale of a similar property can become a key piece of appeal evidence. The County Assessor’s Office can explain which comparable rentals carry the most weight for any given neighborhood.

Arapahoe County Tax District Map and ZIP Code Rates

Mill levies change from one ZIP code to the next because each address sits inside a unique stack of districts. A home in one corner of the county might owe a different school district mill levy than a home in the next ZIP code, and the city or metro district layers add their own amount on top of the county base.

• Pull the parcel record from the Tax Search tool to see the full district list.
• Match each district to its certified mill levy from the official certification file.
• Add the mill amounts and multiply by the assessed value to verify the bill.
• Compare bills to neighbor reports to spot unexpected jumps.

Tax rates by ZIP code tend to move slowly, but metro district debt retirements or new bond issues can shift totals in a single year. The certification file from the County Commissioners is the cleanest source for the exact mills applied to a specific parcel.

New Homeowner Tax Information

Buying a home in Arapahoe County triggers several property tax steps. The title company usually pays the current year’s tax from the sale proceeds and gives the buyer a credit for any future installments. The new owner should still file for the primary residence classification right away to lock in the lower assessment rate that applies to a primary home.

1. Record the deed with the Clerk and Recorder’s Office to update ownership.
2. Apply for the owner-occupied classification if the home is a primary residence.
3. Update the mailing address with the Assessor so future notices arrive on time.
4. Set up a payment plan or reminder for the spring and summer deadlines.

First-year bills can be a surprise because the new owner’s tax share may differ from the seller’s. Watching the first statement closely helps catch errors and confirms that the primary residence credit actually applied.

Property Tax Refund Process

Overpayments and duplicate payments can be refunded once the Treasurer verifies the credit. The refund request usually comes from the owner in writing, and the Treasurer reviews the tax account for any outstanding liens before issuing a check. Refunds tied to successful appeals take longer because the Assessor must record the new value first.

• Confirm the credit balance on the Tax Search report.
• Submit a written refund request to the Treasurer’s Office.
• Include a copy of the canceled check or payment confirmation.
• Allow several weeks for review and check mailing.

Owners who pay ahead for two or more years can request a refund of the overage only after the Treasurer applies the credit. A short call to the Treasurer’s Office clears up any confusion about the timeline for a specific refund case.

File an appeal online before the June 8 deadline by logging into the Taxpayer Portal, selecting “Assessment Appeal,” and uploading your documents. Attend the hearing if required, then await the board’s decision. Successful appeals can lower your assessed value and reduce next year’s taxes.

Are there exemptions that can lower my Arapahoe property tax bill?

Yes. Senior citizens, veterans, and primary residence owners may qualify for specific exemptions. The senior exemption reduces the taxable portion of a home’s assessed value, while the veteran exemption offers a flat reduction. To apply, download the exemption forms from the Assessor’s website, complete them, and submit them by the filing deadline—usually early May. Once approved, the exemption appears on the next tax statement, decreasing the amount you owe.
