The Denton County property tax due date is January 31. Bills are mailed in October or November and are legally due as soon as you receive them, but you have until the end of January to pay in full. Any amount still unpaid on February 1 is delinquent and starts accruing penalties and interest immediately.
When Payment Is Due and When It Goes Delinquent
Under Texas law, your property taxes become due the moment the tax bill reaches you. The practical deadline is January 31 of the following year. On February 1, whatever remains unpaid, in full or in part, is classified as delinquent.1State of Texas. Texas Tax Code Title 1 Section 31-02 – Delinquency Date
One exception shifts the date. If the county mails your bill after January 10, the delinquency date moves to the first day of the next month following the mailing. This mostly affects supplemental bills issued for mid-year value or ownership changes, which typically carry a March 1 delinquency date rather than February 1.1State of Texas. Texas Tax Code Title 1 Section 31-02 – Delinquency Date
The January 31 deadline covers everything on your consolidated bill: Denton County, your city, your school district, and any special districts. One payment settles all of them. If a mortgage escrow account handles your taxes, the lender pays on your behalf, but the legal responsibility to meet the deadline stays with you.
What Late Payment Costs
Miss February 1 and the charges begin stacking the same day. The tax office cannot waive them. Delinquent balances pick up the following penalty and interest each month:
- February 1: 6% penalty plus 1% interest (7% added)
- March 1: 7% penalty, 2% interest (9%)
- April 1: 8% penalty, 3% interest (11%)
- May 1: 9% penalty, 4% interest (13%)
- June 1: 10% penalty, 5% interest (15%)
- July 1: 12% penalty, 6% interest (18%), plus a possible collection penalty
The penalty climbs by one point each month through June and then locks at 12%. Interest, however, keeps accruing at 1% per month indefinitely until the balance is paid, even after a court judgment.2State of Texas. Texas Tax Code Title 1 Section 33-01 – Penalties and Interest
The July 1 Collection Penalty
Accounts still delinquent on July 1 can be hit with an additional charge covering the taxing unit’s attorney fees. State law allows this collection penalty to match the compensation in the taxing unit’s contract with its collection attorney, which can run 15% to 20% of the taxes, penalties, and interest already owed. The tax collector must send a delinquency notice at least 30 days before July 1 warning that the extra charge is coming.3State of Texas. Texas Tax Code Title 1 Section 33-07 – Additional Penalty for Collection Costs
A $5,000 bill ignored through midsummer can grow to roughly $6,900 or more once the full 18% and the collection penalty attach.
Active-Duty Military
If you’re on active military duty, the federal Servicemembers Civil Relief Act caps interest on delinquent property taxes at 6% annually and blocks additional penalties and fees during your service. This covers both real and personal property taxes.
How to Pay Before the Deadline
Pull up your account through the Denton County Tax Office’s online portal, which lets you search by owner name, property address, or account number. Your statement shows the total owed with any exemptions already applied.4Denton County. Online Taxes
Online payment fees depend on method:
- Credit card: 2.10% of the payment (minimum $2.00)
- Debit card: 1.50% of the payment (minimum $2.00)
- E-check: no fee
On a $5,000 bill, paying by credit card tacks on $105 before you’ve touched the tax itself. E-check avoids the surcharge entirely.
If you mail your payment, the postmark controls the payment date. Take the envelope to a Post Office counter for a hand-cancellation, or use Certified Mail so you have proof of the mailing date. Keep the receipt; the Postal Service doesn’t retain copies.6USPS. Mail Your Tax Return with USPS
Denton County also runs six offices with after-hours drop boxes, including locations in Denton, Lewisville, Carrollton, Cross Roads, Frisco, and Flower Mound. A payment placed in a drop box is recorded as received on the date of deposit. The main office is the Mary and Jim Horn Government Center at 1505 E. McKinney Street in Denton.7Denton County, TX.

Installments for Seniors, Disabled Homeowners, and Disabled Veterans
If you’re 65 or older, disabled, or a disabled veteran (or the unmarried surviving spouse of one), you can split your homestead taxes into four equal payments without penalty:
- First installment: before February 1, with written notice to the tax office that you’re electing installments
- Second installment: before April 1
- Third installment: before June 1
- Fourth installment: before August 1
The statute actually allows the first installment and notice up to March 1 and still treats the election as timely. Miss any later installment and the unpaid portion picks up a 6% penalty plus 1% monthly interest, though the escalating February-through-July schedule doesn’t apply. Paying more than the minimum rolls the excess forward. This plan is limited to your residence homestead; investment and commercial property don’t qualify.8State of Texas. Texas Tax Code Title 1 Section 31-031 – Installment Payments of Certain Homestead Taxes
Split Payment Option
Separately, Texas law lets any property owner pay in two halves if the local taxing unit has adopted the option. Half the bill is due before December 1 and the remainder before July 1, with no penalty or interest on the second half as long as you meet the July deadline.9State of Texas. Texas Tax Code Title 1 Section 31-03 – Split Payment of Taxes
Make the first half-payment but miss July 1, and the unpaid portion immediately takes a 12% penalty plus accrued interest. Check with the Denton County Tax Office to confirm the option is active for your taxing jurisdictions before relying on it.2State of Texas. Texas Tax Code Title 1 Section 33-01 – Penalties and Interest
Deferring Taxes if You’re 65+ or Disabled
Homeowners who are 65 or older or disabled can defer collection of homestead property taxes entirely. Delinquency penalties don’t apply while the deferral is in place, though interest continues to accrue at the statutory rate. A tax lien stays on the property, so the balance doesn’t vanish; it waits. Deferral ends when you no longer own or occupy the home, at which point the accumulated taxes, interest, and any penalties become payable.10Denton County, TX. Exemptions and Deferrals
Deferral suits homeowners on fixed incomes who plan to stay in the house long-term. The trade-off is a growing balance against your equity, settled when the property changes hands.
Challenging the Valuation Happens Earlier
If your concern is that the bill itself is too high, note that the window to protest closes well before the bill arrives. The Denton Central Appraisal District handles valuations, and protests must be filed by May 15 or 30 days after the district mails your notice of appraised value, whichever is later. Waiting until the October or November tax bill to dispute the number is too late for that year.11Denton County. Denton County – How to Protest
