Last updated November 13, 2026. Figures come from the official city, county and appraisal district pages linked in Sources, the Texas Property Tax Code and the U.S. Census Bureau. A figure appears only where we could confirm it on an official page.
Plano property tax is billed by several taxing units, and we could not confirm the city’s adopted rate from an official page for this guide. The city, Collin County, your school district and any special districts each set a rate, and the combined rate is on your tax statement.
Texas property taxes are due by January 31 and turn delinquent in February, and unpaid tax stays attached to the house until it is paid.

How the city tax fits on your Plano bill
Several governments tax the same house, and each sets its own rate. The county appraisal district sets the value of your property, each taxing unit adopts a rate, and one tax office sends the bill.
In Plano that can include the city, Collin County, your school district and special districts such as water or road districts. The rates for each unit are printed on your tax statement and published by the appraisal district.
Plano homes and homeowners
The Census Bureau’s 2020-2024 estimates put the median home value in Plano at $465,900 and the median household income at $112,253. Homeowners reported paying a median of $6,700 a year in real estate taxes. About 57 percent of occupied homes are owner-occupied, and the median home was built in 1993.
The city had an estimated 293,028 residents in 2025 (Census Bureau). A house built around 1993 is often far older than the newest neighborhoods in the same county, and each neighborhood can sit inside different special districts with their own rates. That is one reason two homes of the same value in the same city can get different tax bills.

Use these two to estimate your annual bill and the cost of paying late. Add the county, school and district rates from your own statement.
Estimates only. The bill estimate multiplies taxable value by the rates you enter. The late-payment estimate uses the penalty and interest percentages in Texas Property Tax Code Sec. 33.01 for February through July. In July the estimate also shows the largest collection penalty an attorney can add under Sec. 33.07.
When are Plano property taxes due?
Texas property taxes turn delinquent if they are not paid by January 31 of the following year, so taxes for 2026 are due by January 31, 2027 (Sec. 31.02). That date is a Sunday. Under Property Tax Code Sec. 1.06 a deadline that falls on a weekend moves to the next business day, so the last day to pay without penalty is Monday, February 1, 2027. After that, penalty and interest build month by month.
| Month paid | Penalty | Interest | Total |
| February | 6% | 1% | 7% |
| March | 7% | 2% | 9% |
| April | 8% | 3% | 11% |
| May | 9% | 4% | 13% |
| June | 10% | 5% | 15% |
| July | 12% | 6% | 18% |
The penalty stops at 12 percent and interest keeps rising 1 percent a month after that (Sec. 33.01). Not getting a bill does not change the due date, the penalty or the lien.
How do I look up or pay my Plano property tax bill?
- Look up your value and exemptions: Central Appraisal District of Collin County property search.
- Ask the tax office named on your statement for the amount due in your closing month if you plan to sell.
- Check with your lender: if a servicer pays from escrow, ask for proof that it paid before the deadline. The lien stays on the house until the tax is paid.
What happens if I don’t pay property taxes in Plano?
A tax lien attaches to the property every January 1 (Sec. 32.01). Whoever owns the property on that date is personally liable for that year’s tax, and selling the house does not end that liability (Sec. 32.07).
Real property accounts still unpaid on June 30 can be sent to a delinquent tax attorney, who can add a penalty of up to 20 percent of the taxes, penalty and interest owed (Sec. 33.07). If the account stays unpaid, the taxing units can sue to foreclose the lien and sell the property.
The tax office cannot waive penalty or interest. Only the governing body of the taxing unit can, in the situations listed in Sec. 33.011.
Can an exemption or protest lower my Plano bill?
Collin County's 2026 table of rates and exemptions by jurisdiction lists a 20 percent homestead exemption (minimum $5,000) for Plano, $40,000 for homeowners 65 or older and $40,000 for disabled homeowners.
For school district taxes, a homeowner’s residence homestead exemption is $140,000, and homeowners 65 or older or disabled get an additional $60,000 (Sec. 11.13). You apply through the appraisal district, not the tax office. A late homestead application can be filed within two years after the delinquency date (Sec. 11.431). To protest your appraised value, file by May 15 or 30 days after the appraisal district delivers your notice, whichever is later (Sec. 41.44).
Homeowners 65 or older, or disabled, can ask in writing to pay the homestead tax in four installments without penalty or interest (Sec. 31.031).
How to sell a house in Plano that owes property taxes
- Ask the tax office for the amount due in the month you expect to close, including any attorney fee if the account is already delinquent.
- Give that figure to the title company. Taxes are paid from the sale proceeds at closing, ahead of what you take home.
- Compare offers on what you actually net after taxes, repairs, commissions and closing costs.
- If time matters, ask for a written cash offer with a closing date you choose. We buy houses as-is, with no repairs and no agent commission. See how we buy houses in Plano.
