Texas is famous for having no state income tax. What gets less attention is that the state funds its government largely through property taxes — and Texas property tax rates are consistently among the highest in the nation. For DFW rental owners, this trade-off has a direct impact on every month's cash flow. Understanding exactly how property taxes affect your numbers is essential to underwriting any Texas rental correctly.
The No-Income-Tax Trade-Off
Texas collects no personal or corporate income tax. That's a genuine advantage for residents and businesses. The state instead relies heavily on sales tax and local property taxes to fund government services — particularly schools, which consume the largest share of most Texas tax bills. The result is that DFW landlords pay 2.0%–2.5% of their property's assessed value in property taxes every year, depending on the county and any overlay districts.
On a $300,000 rental home, that's $6,000–$7,500 per year in property taxes alone. That's $500–$625 per month coming off the top of gross rent before you've paid a single dollar in insurance, maintenance, management fees, or debt service. Property taxes are the single largest operating expense on most DFW rentals — and they're non-negotiable.
What the Numbers Look Like Across DFW
Property tax rates vary across DFW counties and even within counties depending on which taxing entities apply to a given address. Here's a general landscape:
- Collin County (Frisco, McKinney, Allen, Plano): typically on the lower end of the DFW range, often 1.9%–2.2% base rate for residential properties.
- Dallas County (inner city, Irving, Garland, Mesquite): rates often 2.2%–2.5% base, with some inner-city areas carrying additional special district overlays that push effective rates higher.
- Tarrant County (Fort Worth, Arlington, Mansfield): variable by city, generally 2.0%–2.4%.
- Outer growth corridors (Celina, Anna, Aubrey, Midlothian): base county rates can be lower, but MUD and PID overlay rates commonly push effective total rates to 2.5%–3.0% or higher.
The only reliable way to know your number is to pull the actual tax certificate for the specific property, not rely on county CAD averages. Every county in Texas has a public Central Appraisal District (CAD) portal where you can search by address and see the current assessed value and breakdown of applicable taxing entities.
How This Changes Your NOI Calculation
Here's a concrete example using a $1,700/month rental with $7,000/year in property taxes:
Property taxes alone consume $583 of a $1,700 rent — 34% of gross rent. This is why landlords who model expense ratios based on national averages consistently overshoot their projected returns in Texas. The expense structure here is different, and the models need to reflect that.
The Homestead Exemption — You Don't Get It
Texas offers a homestead exemption to owner-occupants that reduces the assessed value used to calculate school taxes. The general homestead exemption saves owner-occupants approximately $100,000 off the school district portion of their assessed value — a meaningful reduction in their annual tax bill. Investors who rent out their properties do not qualify for the homestead exemption on those properties.
This is a critical underwriting point when evaluating properties that are currently owner-occupied. The seller's tax bill reflects the homestead exemption. Your tax bill as the new investor-owner will not. The actual tax burden on the property after you purchase it may be 15–25% higher than what the seller currently pays. Pull the non-homestead assessment from the CAD when building your pro forma.
Protesting Your Assessment Every Year
Texas law gives every property owner the right to protest the county Central Appraisal District's assessed value annually. A successful protest reduces the assessed value, which reduces your tax bill and improves NOI. The protest process is accessible — you file a notice of protest by the deadline (typically May 15 in most Texas counties), then present evidence to support a lower valuation.
Many DFW landlords who protest consistently save $500–$2,000 per year per property. Across a multi-property portfolio, that adds up to meaningful annual savings. Evidence that supports a lower value includes recent sales of comparable properties at prices below your assessed value, photos of condition issues not reflected in the valuation, and income-based appraisal data for income-producing properties.
A good property manager tracks your assessment annually and flags the protest deadline. Missing May 15 means waiting another full year.
Four Things You Can Do Right Now
1. Factor the full tax rate into your rent from day one. Don't model at a percentage of market rent — model from the actual tax certificate. Build in the full effective burden including any MUD/PID overlays.
2. Protest your CAD assessment every May. It costs nothing but time. Consistent protesters save more than those who file only when they see a big jump.
3. Use a flat-fee property manager so your management cost doesn't scale with rent. With a percentage-based manager at 8–10%, a $1,700/mo property costs you $136–$170/mo in fees. With ManageWithEXL's $99/mo flat fee on the Essential plan, that same property saves you $37–$71/month — $444–$852/year — that goes directly into NOI.
4. Budget taxes as a monthly reserve, not an annual expense. Property taxes are due in January and February in Texas, but the liability accrues monthly. Treating them as a monthly line item prevents cash flow shock when the bill arrives.
