Dallas Property Tax Calculator (2026)

Dallas ISD is the largest single line at $0.994 per $100 — about 44% of the typical bill. The City of Dallas adopted a slight rate decrease for 2025 but rising appraised values mean the average bill still ticked up. If you bought before 2020, the 10% homestead appraisal cap is doing serious work for you.

The combined rate above assumes you’re inside Dallas city limits and in the listed ISD. Cross any of those boundary lines and the math changes.

These numbers use the typical combined rate and apply the $100,000 school-district homestead exemption against the full taxable value for simplicity. Your actual bill may differ by 3–8% depending on your exact taxing units and any additional local exemptions you qualify for.

Devon closed on a $425,000 craftsman in Oak Cliff in March 2026. The 2025 certified value was $410,000 (the prior owner had a long-tenured homestead cap). DCAD will reappraise to market for 2026 — Devon should expect roughly $9,100 in tax the first year if he doesn't file homestead, or about $7,200 after he files (saving ~$1,000 from the ISD exemption and another $400+ from Dallas County's optional 20% homestead).

Drop in your home’s value. The estimator uses Dallas’s typical combined rate but you can tune it for your exact ISD/MUD. The $100,000 homestead exemption can be toggled.

Rates vary across Dallas County based on which ISD, city, and special district your address falls inside. Suburbs often run lower than the central city, primarily because their school district rates are lower.

Dallas County offers a generous 20% optional homestead exemption on top of the state $100k school exemption. Many homeowners miss the application. It's free, one-time, and the filing window opens January 1.

The Dallas Central Appraisal District reappraises Dallas County residential property every January 1. Notices of Appraised Value mail in mid-April, with a protest deadline of May 15 or 30 days after the notice date — whichever is later. DCAD's online iFile portal at dallascad.org handles roughly 70% of protests; the rest run through informal phone hearings or formal Appraisal Review Board (ARB) panels.

Most successful protests cite three or four recent comparable sales within a half-mile that closed below your appraised value, photos showing condition issues (foundation settlement, outdated kitchens, deferred roof work), or boundary problems. DCAD appraisers are receptive to comp-based arguments and skeptical of "the market's overvalued" arguments without specifics.

The informal hearing — 10-15 minutes with a DCAD appraiser, often by phone — resolves most cases. Escalating to the formal ARB adds 20-30 minutes and an independent three-member panel that tends to side with prepared homeowners. After ARB, remaining options are binding arbitration (residential under $5M, $500 deposit refundable if you win) or district court litigation (rare for residential).

The three highest-frequency Dallas protest mistakes: filing without comps, missing the deadline, and walking into ARB without a one-page evidence sheet. If you don't have time, Dallas-area contingency-fee firms (Ownwell, Five Stone Tax, Resolute Property Tax, Watchtower) charge 25-40% of first-year savings with nothing upfront.

Dallas County trimmed its rate from $0.227 per $100 in 2022 to $0.2155 in 2025 — a real but modest cut. The City of Dallas held its rate roughly flat near $0.70. The Dallas ISD rate actually fell from $1.18 in 2022 to $0.994 in 2025, driven by state-mandated school finance compression (Senate Bill 2 in the 2023 session).

Despite the rate cuts, the typical Dallas homeowner saw their bill rise 12-18% over those three years because appraised values rose faster than rates fell. The 10% homestead cap absorbed some of the value growth for tenured homeowners; new buyers absorbed the full delta on their first reappraisal. SB 2 also raised the school homestead exemption from $40,000 to $100,000, which materially offset the rate-versus-value dynamic for owner-occupants.

For 2026, expect another modest rate adjustment from Dallas County and the City; the ISD rate is largely outside local control because Texas school finance pulls or pushes the rate via the state's recapture and compression formulas. Watch the Dallas City Council's August budget hearings — that's where the city rate is set.

Most Dallas homeowners only know about the $100,000 state school exemption. The full stack available to a single owner-occupant in the City of Dallas, Dallas ISD, and Dallas County:

• State school homestead: $100,000 off ISD value (statutory)
• Dallas County optional homestead: 20% off appraised value, minimum $5,000
• City of Dallas optional homestead: $90,000 flat off city taxable value (one of the most generous in Texas)
• Parkland Hospital District optional: 20% off, minimum $5,000
• Dallas College optional: 1% off, minimum $5,000
• Over-65 or disabled: additional $10,000 ISD + $107,000 city + $107,000 county exemption layers, plus a tax ceiling that freezes school taxes at the year-65 amount
• Disabled veteran: $5,000-$12,000 sliding by disability rating; 100% rating = full exemption
• Surviving spouse: continues any qualifying exemptions for the eligible survivor

The full stack for a homesteaded owner-occupant typically saves $2,000-$2,800 per year on a $400,000 home. Most homeowners only capture the state portion (~$1,000). Filing all of them takes ten minutes through dallascad.org and the savings continue automatically year after year.

Scenario 1 — First-time buyer, $375k Lakewood bungalow, 2026 close. Tax bill year one with no homestead filed: about $8,350. After filing all available exemptions in the same tax year (filing window opens January 1 and runs through April 30): about $6,200. The $2,100 difference is the single best ROI for ten minutes of paperwork in Dallas County.

Scenario 2 — Long-tenured owner, 2014 purchase, $725k market value, $440k capped taxable value. With homestead and the over-65 ceiling: about $5,800 a year. The market value is $725,000 but the homestead cap held the taxable value to $440,000 across a decade of 8-15% annual appreciation. The cap is doing $5,500 of work every year. This is why long-tenured Dallas homeowners pay less than recent buyers next door with identical homes.

Scenario 3 — Investment property, no homestead, $325k duplex in the M Streets. No homestead because not owner-occupied. Annual tax: about $7,250 (full 2.23%). Investors should also model rate trajectory — Dallas County rates have trended down 5-8% over three years, which marginally improves cash-on-cash returns over a 7-10 year hold.

If you finance through any major lender — Chase, BofA, USAA, Texas Capital, or a local credit union — Dallas property tax is almost always escrowed. The lender collects 1/12 of estimated annual tax with each mortgage payment plus a 2-month cushion under federal RESPA rules. On a $400,000 Dallas home with homestead filed, monthly tax escrow runs roughly $500-$575.

Two timing surprises that catch first-year Dallas homeowners:

• Year-one escrow shortage. Lenders often estimate based on the prior owner's tax bill, which carried a homestead cap. Your unhomesteaded first-year bill is higher. Expect a shortage letter in late summer 2027 covering 2026 underfunding — typically $1,500-$3,000 on a mid-priced home. Either pay direct or spread it across 12 months.
• Year-two recalibration. After your first homestead-adjusted bill, escrow resets. Some lenders refund excess; some apply it to your new target. Request a fresh escrow analysis after filing homestead, refinancing, or any year where DCAD's valuation shifts materially.

If you're tax-savvy and want to keep the float, you can request to opt out of escrow on conventional loans with 20%+ equity. Most lenders permit it but some charge a small rate adjustment. FHA and VA loans require escrow.
