Dallas County homeowners who are 65 or older, or disabled, do not have to hand over the whole 2026 property tax bill by the end of January. The county Tax Office lets those owners pay in four equal quarters with no penalty or interest, so long as the first quarter is in by the Jan. 31 delinquency date. The plan is not automatic, though, and one calendar quirk in 2027 makes the schedule worth a close look.
Quarter Pay: four equal payments and one date that decides it
The Tax Office calls the arrangement the Over-65/Disabled installment plan, or Quarter Pay. Its Payment Arrangements page describes four equal payments, each one a quarter of the total due, with payment dates of Jan. 31, March 31, May 31 and July 31.
Only the first date carries the protection. The page says no penalty or interest applies when “the first installment (1/4 of the total amount due) is paid before the delinquency date.” Taxes become delinquent if paid after Jan. 31, and the county says state law requires penalties and interest on anything paid later.
Homeowners 65 and older, and disabled homeowners, who want to spread the 2026 bill have one thing to settle before January: whether their account is eligible, and whether they can send one quarter of the total by Jan. 31. Nothing in the county’s description suggests the plan switches on by itself; it is something an owner has to open.

That makes the first quarter the real deadline, not the sign-up. An owner who enrolls in December and never sends the January payment has an enrolled plan and a delinquent bill. The Tax Office mails coupons for the remaining three payments only after the first one posts.
Dallas County statements go out in October, and the county lists Oct. 1 as the date taxes are due. For a household that gets its bill this month, the stretch between the mailbox and Jan. 31 is the window to decide whether a quarter of the bill is manageable on a fixed income.
Why the portal front page does not show the plan
Dallas County’s online tax lookup and payment application links out to the Tax Office home page and a pay-property-tax banner. It carries no installment text, no deadline and no count of payments. A senior who goes looking there for the plan will not see it described.
The county says owners enroll themselves inside that application. They enter their information, select the account, and click the yellow payment plan options tab. In the Tax Office’s words, “The Installment Agreement option will appear if the account is eligible.” If the option is missing, the account is not set up as an eligible one.
Payment is by eCheck with no added fee, according to the Tax Office’s billing and payments page. Credit and debit cards are accepted too, but through Chase with convenience fees the page does not put a number on. On a payment of a quarter of the bill, the choice of method is the one place the plan can cost money.
The plan only reaches owners who already hold the exemption
The plan is limited to homestead property, and the owner has to qualify for the Over 65 or Disabled exemption. That exemption is granted separately, by the appraisal district, and the county’s own wording ties the installment plan to owners who already qualify for it.
The state’s Comptroller’s exemptions page says the Tax Code requires school districts to give an additional $60,000 residence homestead exemption to owners who are 65 or older or meet the Social Security Administration’s disability definition. It also says the general deadline to file an exemption application is before May 1.
The county’s billing page also lists a separate item that is easy to confuse with the plan: deferred taxes, which it says carry 5 percent annual interest. A deferral pushes the bill off and charges for the delay. Quarter Pay spreads it across the year and charges nothing, provided the first payment is on time.
A Sunday deadline and a holiday in the middle of the schedule
The calendar adds a wrinkle for the 2026 bill. Jan. 31, 2027 falls on a Sunday. The Tax Office pages give Jan. 31 as the delinquency date and do not say what happens when it lands on a weekend, so an owner counting on Monday has nothing from the county in writing to stand on.
The later dates are no friendlier. March 31, 2027 is a Wednesday, but May 31 is a Monday, which is Memorial Day, and July 31 is a Saturday. Three of the four listed dates land on a weekend or a federal holiday, and the Tax Office does not say how it treats them.
The practical test is whether a payment made online by eCheck before the weekend posts under the date the county records. The Tax Office does not publish a posting rule on these pages, and its Customer Care Center is listed at 214.653.7811. The payment that matters most is the first one.
Payment is flexible in one direction. An owner can pay more than the scheduled quarter, or the full balance, at any time.
Can a fixed income carry the first quarter by Jan. 31?
The risk for a Dallas County owner is not the schedule, it is the first quarter: a late or missed payment on a Sunday-ending deadline turns a four-payment plan into a delinquent bill with penalties and interest.
The Senior Property Tax & Home-Cost Relief Kit takes an owner through reading a tax bill line by line, in Part 2, and includes an application log and renewal calendar, so the exemption paperwork and the January payment are tracked in the same place.
