Denver Property Tax Due Dates: First Half, Full Payment and Second Half
Denver lists the first-half due date as the last day of February, the full-payment due date as April 30, and the second-half due date as June 15. If a due date falls on a weekend or holiday, Denver moves the due date to the next business day.
| Payment option | Official due date | Practical action |
|---|---|---|
| First half | Last day of February | Use if splitting taxes into two payments. Confirm first-half amount on statement. |
| Full payment | April 30 | Use if paying the full tax bill at once. Check if any service lien requires full payment. |
| Second half | June 15 | Due if first half was paid. Unpaid taxes can become delinquent after the second-half deadline. |
Deadline mistake to avoid
Do not wait until the last day to find your Parcel ID or test the payment screen. Large card payments, browser issues, bank blocks, eCheck filters, mortgage-company confusion and wrong-parcel searches can delay payment.

Denver Delinquent Property Taxes, Interest and Tax Lien Sale Help
Denver says past-due property taxes accrue interest at 1% per month. If taxes remain unpaid, Denver sends a delinquency notice in July, advertises unpaid taxes and may sell the tax lien if the balance is not paid before the November public auction.
Delinquent interest
Denver lists 1% per month once payment is past due. Do not use an old balance for a late account.
July notice
If taxes are unpaid, Denver says a delinquency notice is sent in July. Compare parcel, payment history and escrow records quickly.
November tax lien auction
Denver says the public real estate tax lien auction is usually held in November. A tax lien is being sold, not the property immediately, but the risk is serious.
Denver Delinquent Interest Planning Tool
This tool estimates 1% monthly interest for planning only. Denver Treasury must verify the official payoff amount.
What to ask before paying a late bill
- What is the exact payoff amount today?
- Does the amount include delinquent interest, penalties and fees?
- Has the account been advertised for tax lien sale?
- Is the parcel scheduled for the public auction?
- What payment methods are accepted now?
- How can Denver confirm the account is cleared after payment?
Denver Treasury vs Assessor: Who Should You Contact?
If the issue is payment, call Treasury. If the issue is valuation, assessed value, property classification or property record details, start with the Assessor’s side.
Use Treasury for
- Property tax payment.
- Business personal property tax payment.
- Tax statement and Parcel ID payment questions.
- Payment receipt or duplicate payment questions.
- Delinquent taxes and payoff help.
- Tax lien sale questions.
Use Assessor for
- Actual value.
- Assessed value.
- Property classification.
- Ownership and property records.
- Assessment history.
- Value protest questions.
Important value warning
Disputing value does not automatically stop property tax payment deadlines. Ask the correct Denver office what must be paid while a value or assessment question is open.
Denver Property Tax Relief, Exemptions and Deferral Programs
Denver’s property tax information page points taxpayers to city and state relief resources, including Denver Property Tax Relief, Colorado Property Tax Deferral, Denver Property Tax Exemption, Colorado Property Tax Exemption and senior-related classification information.

- Payment date.
- Confirmation number.
Common Denver Property Tax Payment Mistakes to Avoid
Most Denver tax payment problems come from using the wrong parcel, waiting too close to the deadline, mailing without a valid parcel number, or confusing payment issues with value issues.
Wrong parcel ID
Match Parcel ID, property address, owner and tax year before paying. If you own multiple properties, repeat the statement process for each one.
Bank rejection
Denver suggests notifying your bank before large payment attempts. A rejected payment near a deadline can create late-payment stress.
Business account debit filter
Denver says business bank accounts using debit filters or blockers must update Denver’s company ID to avoid eCheck/EFT payments being returned as not authorized.
Service lien confusion
Installment payments are not allowed on service lien and maintenance district payments. Read the amount due carefully.
