Property Taxes in Duncanville, TX

By Mariela Lovo Ol, REALTOR® · Updated

Property taxes in Duncanville, TX combine the rates of Dallas County, two regional districts, the city and Duncanville ISD. The whole city is in one county and one school district. So the math is simpler than in many suburbs. Here are the 2025 rates, exemptions and deadlines.

How is a Duncanville property tax bill built?

The Dallas Central Appraisal District sets each home's value every year. Each taxing unit applies its rate per $100 of taxable value, after the exemptions it offers.

Before you make an offer, search the address on the DCAD site. You will see its taxing units, exemptions and past values.

What are the 2025 tax rates for a Duncanville home?

Dallas Central Appraisal District lists these 2025 rates per $100 of value. Dallas County: $0.2155. Parkland Hospital: $0.212. Dallas College: $0.106575. City of Duncanville: $0.600166. Duncanville ISD: $1.1057.

Together they add up to about $2.24 per $100 before exemptions.

Which exemptions lower a Duncanville tax bill?

File for the residence homestead exemption once the home is your main home. School districts must exempt $140,000 of a homestead's value. Owners 65 or older or disabled get another $60,000 school exemption.

In 2025, the City of Duncanville had no percent homestead exemption. It did offer $40,000 for owners 65 or older or disabled. Dallas County, Parkland Hospital and Dallas College each offered 20% plus $100,000 for those owners.

Once a homestead qualifies, its taxable appraised value cannot rise more than 10% a year, starting the next tax year. The general deadline is before May 1. DCAD does not charge to file.

What would taxes be on a $300,000 Duncanville home?

This example uses 2025 rates for a homestead appraised at $300,000, with no age or disability exemptions. County, hospital and college taxes on $240,000, after their 20% exemption: about $1,282. City tax on $300,000: about $1,801.

School tax on $160,000: about $1,769. The total is about $4,851 a year. Your bill will differ, and 2026 rates are being set this fall.

How do protests, MUDs and PIDs work in Duncanville?

Each spring DCAD mails notices of appraised value. You can protest to the Appraisal Review Board by May 15 or 30 days after the notice was mailed, whichever is later. DCAD's uFILE system lets you file online.

A home may be in a municipal utility district (MUD) or public improvement district (PID). If so, the seller must give written notice before you sign. Check the DCAD record for any special district.
