Texas has no state income tax. The trade-off? Property taxes that can eat your NOI alive. Harris County's effective tax rate runs 2.2-2.8% of assessed value — and when you buy a multifamily property, the county reassesses to your purchase price. This is one of the biggest hidden costs in Houston acquisitions, as highlighted in our Q1 2026 market update.
On a $1.2M acquisition, that's $26,400-$33,600/year in property taxes. Get it reduced by 15-20% through a protest, and you're saving $4,000-$6,700 annually — every year, compounding.
Why This Matters More for Investors
When you buy your primary home in Texas, assessed value is capped at 10% annual increases (homestead cap). Investment properties have no such cap. The appraisal district will reassess to market value every year.
| Scenario | Property Tax | As % of NOI |
|---|---|---|
| $1.2M property, 2.4% rate | $28,800/year | 25-35% |
| After 15% protest reduction | $24,480/year | 21-30% |
| Annual savings | $4,320 | |
| Added value at 7.5% cap | $57,600 |
Every multifamily investor in Texas should protest every year. The process is free, the downside is zero, and the success rate is 60-70%.
The Timeline
| Date | Event |
|---|---|
| January 1 | Valuation date — property valued as of this date |
| April 1-15 | HCAD mails Notice of Appraised Value |
| May 15 | Protest deadline (hard deadline, no exceptions) |
| June-October | Informal and formal hearings |
| November-December | Final value set, tax bill issued |
Pro tip: File your protest the day you receive the notice. You can prepare evidence later — but missing the May 15 deadline means you're stuck for the year.
The Evidence That Wins
1. Income Approach (Most Effective for Multifamily)
Your strongest weapon. You're arguing: "Based on actual income, this property is worth less than assessed." (If you're not sure how to calculate NOI, see our underwriting guide.)
Evidence to gather:
- Actual rent roll showing current rents
- T-12 operating statement (real income and expenses)
- Vacancy and collection losses documented
- Operating expense detail (management, insurance, maintenance, utilities)
Calculate:
Your NOI: $85,000
Market cap rate: 8.5%
Indicated value: $85,000 / 0.085 = $1,000,000
If HCAD assessed at $1,200,000 but income only supports $1,000,000, you have a strong case for a $200K reduction.
2. Sales Comparison Approach
Show comparable properties that sold for less per unit or per square foot:
- Same submarket or similar area
- Similar size (units and sqft within 20%)
- Similar age and condition
- Sold within the last 12 months
3. Condition Arguments
Document deferred maintenance with cost estimates:
- Foundation issues (engineer's estimate)
- Failing HVAC systems
- Roof damage
- Plumbing issues
- Code violations
Each deficiency is subtracted from assessed value.
The Hearing
Informal Hearing (First Step)
Phone or in-person with an HCAD appraiser who can negotiate.
- Bring printed evidence
- Lead with your income approach
- The appraiser often counters between your value and theirs
- If you agree, sign the settlement — it's binding
- Success rate: 60-70%
Formal ARB Hearing (If Informal Fails)
Panel of citizen volunteers. You present evidence, HCAD presents theirs, board votes.
- More structured, 15-20 minutes to present
- Bring organized, printed evidence
- Visual aids (charts, photos) are effective
- Decision is binding (can appeal to district court for large amounts)
DIY vs. Hiring a Firm
| Approach | Cost | Time | Best For |
|---|---|---|---|
| DIY | $0 | 4-8 hours | First-time, learning the process |
| Professional firm | 25-40% of savings (contingency) | 30 minutes | Multiple properties, time > money |
Recommendation: DIY your first protest to understand the process. For subsequent years or multiple properties, hire a firm on contingency — you pay nothing if they don't save you money.
Post-Acquisition Tax Strategy
Year of Purchase
File a protest immediately. Your argument: the purchase price already reflects market value, so any assessment above it is unsupported. If assessment equals purchase price, argue the income approach — actual NOI often supports a lower value.
Year 2+
Continue protesting annually. As you execute your value-add renovation plan and raise rents, HCAD doesn't see improvements immediately. There's a 1-2 year lag — use it to your advantage.
Pro tip: When underwriting a new acquisition, always budget property taxes at purchase price x local tax rate. Never use the seller's current tax bill — it's irrelevant. House hackers should be especially careful here, as reassessment on a fourplex can add $200-$400/month to your costs.
