The five pillars in practice

Abbott's proposal, as described in 2025–2026 coverage and policy analyses, rests on five main pillars: stricter local spending limits, a requirement that two‑thirds of voters approve certain tax increases, strengthened rollback elections, a five‑year appraisal cycle with a three‑percent cap, and the gradual elimination of school M&O property taxes for homesteads via constitutional amendment. Each of these elements is incremental, adjusting the rate at which property tax burdens grow rather than changing the underlying tax base.

The most far‑reaching element—the state assuming school M&O for homesteads—depends on the continued presence of sizable state budget surpluses. Public statements about the plan emphasize that "there is no need to raise the sales tax" because the state "already has the money" to fund the promised relief. That claim is only true if the unusually large surpluses of the last biennium persist indefinitely.

The Prop 13 problem with appraisal caps

Abbott's proposed 3% annual appraisal cap mirrors California's Proposition 13 (which caps at 2%). Research from NBER (Wasi & White, 2005) found that Prop 13 caused a substantial increase in average tenure for California homeowners (10% increase) and renters (19% increase), creating a severe lock-in effect. The Buffett example is instructive: Warren Buffett pays $2,264/year on a $4 million California home (0.056% effective rate) vs. $14,410/year on a $500,000 Nebraska home (2.9%).

ITEP's 2025 analysis found that Prop 13 "contributed to the state's housing shortage, as declining property tax revenues led municipalities to seek revenue from sales and hotel taxes, leading to the proliferation of retail and hotel properties at the expense of housing development." A 3% cap in Texas would replicate these distortions while failing to address the fundamental problem: the existence of the property tax itself.

Surplus dependency vs. structural reform

The surplus itself is a product of transient conditions: COVID‑era federal transfers, inflation‑driven nominal revenue growth, and conservative spending choices that may not be sustainable in a recession. The state plans to spend $51 billion over 2 years on property tax cuts—about $1 of every $6–7 in the state budget. Budget analysts warn this is "not financially sustainable." Texas's sales tax revenue growth has slowed from double-digit pandemic-era surges to ~4% annually.

By contrast, the 5% flat sales tax plan does not depend on surpluses. Using Q3 2025 annualized gross sales of $3,468.3B, a 5% rate generates approximately $173.4B—easily covering the $142.8B replacement need (all property taxes + franchise tax + existing sales tax) with a $30.6B buffer.

Distributional blind spots

The five‑point plan is framed in terms of relief for "homeowners," a group that covers about 6.76M of Texas's 10.75M households. The remaining 3.99M renter households—disproportionately lower‑income and more likely to be Black or Hispanic—see no direct reduction in their housing costs. The homestead exemption increase (to $100K, then $140K) removed 1.3 million homes from the school M&O tax rolls—49% of those homes are owned by Hispanic Texans, 10% by Black Texans—but left renters entirely outside the relief zone.

HB 9: Business Personal Property Exemption

Sponsored by Rep. Morgan Meyer (R-University Park) and a top priority of House Speaker Dustin Burrows, HB 9 raised the BPP tax exemption from $2,500 to $125,000 per business location for tangible personal property held for income production (inventory, equipment). It passed the 89th Legislature, was signed by the Governor on June 12, 2025, and took effect January 1, 2026 after voters approved Proposition 9 in November 2025. The state picks up lost school district revenue; cities and counties must raise rates or absorb the loss.

SB 4 / SJR 2: Homestead Exemption Increase

Lt. Gov. Dan Patrick's top priority, SB 4 passed the Senate 30-0. It raised the school district homestead exemption from $100,000 to $140,000 for most homeowners and $150,000 for those 65+ or disabled. Voters approved the constitutional amendment in November 2025, applying retroactively to 2025 tax bills. The estimated annual cost to the state is $4.6 billion, backfilled through general revenue.

HJR 115: Homeowner M&O Elimination

Filed in March 2025, HJR 115 proposes a constitutional amendment to eliminate school maintenance and operations property taxes for homeowners. However, this only targets the homestead portion—apartment complexes, stores, commercial buildings, and non-homesteaded residential properties remain fully taxable. Like Abbott's plan, it would require the state to perpetually backfill approximately $18–22 billion per year from general revenue.

SB 10: The 1% City/County Cap That Failed

SB 10 proposed capping city and county property tax revenue growth at 1% per year. City officials from Austin, Georgetown, Fort Worth, and McAllen testified against it, warning of cuts to police, fire, and basic services. Austin's testimony was stark: "So just to pay our city workers who serve our city...puts us at that structural deficit." The measure passed the House in August 2025 but died in the legislature in September 2025.

Municipal opposition to property tax elimination

Cities and counties have been among the most vocal opponents. In 2024, cities collected $15.7 billion and counties collected $15.7 billion in property taxes—together ~36% of all property tax revenue. Unlike school districts, cities and counties receive no state replacement funds under most proposals. If property taxes are replaced only at the school district level with state sales tax revenue, city and county property taxes would remain—meaning residents would pay higher sales taxes plus unchanged city/county property taxes. The 5% Plan resolves this by eliminating the entire levy.

TTARA's core position

TTARA's 2025 Statement of Principles states: "TTARA opposes the replacement of property taxes with an enhanced sales or consumption tax, unless the following conditions are met: (a) the net tax burden on business does not increase; (b) the new taxes are economically neutral, do not distort economic decision-making and can be reasonably administered; (c) the new system allows local governments financial stability and reasonable [autonomy]." These conditions are reasonable and—the 5% Plan's proponents argue—are satisfied by the full gross sales approach.

Where TTARA's analysis goes wrong

TTARA's August 2024 research report calculates that replacing all property taxes would require a combined state+local sales tax rate of 19.27%. This calculation starts from the current taxable base of approximately $749 billion. The problem: TTARA's calculation divides $82.1B by a base that represents only 23% of total reported gross sales. The remaining 77%—wholesale trade, manufacturing, professional services, and other B2B flows—generates $867.1B per quarter (Q3 2025) but is not in the current sales tax base.

The 5% Plan proposes taxing the full gross-sales base at a single flat rate, eliminating all existing exemptions. On the Q3 2025 annualized base of $3,468.3B, a 5% rate generates $173.4B—well above the $142.8B replacement need.

TPPF's framework

The Texas Public Policy Foundation has been the most prominent advocate for eliminating property taxes. Their January 2022 report "Lower Taxes, Better Texas" argues for replacing property taxes with a broad-based consumption tax. Key elements include: no net increase in business tax burden, economic neutrality, and reasonable administration. TPPF has responded to Wall Street Journal criticism, but has not endorsed a specific replacement rate—leaving room for the 5% Plan's data-driven approach to fill this gap.

The B2B pyramiding concern—and the 5% Plan's answer

Both TTARA and NCSL raise legitimate concerns about B2B tax cascading (pyramiding) when business inputs are taxed. Under traditional sales tax expansion, taxing B2B services creates an effective tax rate ~25% higher than the stated rate. The 5% Plan addresses this differently: by applying a single uniform 5% rate across all transactions and eliminating the property tax and franchise tax simultaneously, it removes the current embedded property tax cascade in business costs (which already functions as a hidden B2B tax) and replaces it with a transparent, visible, flat-rate levy. The net effect on most businesses is neutral to positive because the eliminated property tax and franchise tax burdens exceed the new 5% sales obligation.

Step 1: Start from a narrow base

Many back‑of‑the‑envelope critiques begin by taking Texas's retail sales—roughly the portion already in the current sales‑tax base—and then asking what rate would be required on that base alone to replace all property taxes. Because this approach ignores wholesale trade, B2B services, manufacturing, and other large sectors, the denominator in the rate calculation is too small, and the resulting rate is artificially inflated.

Step 2: Ignore the Comptroller's own data

The Comptroller's quarterly State Sales and Use Tax Analysis reports $867.1B in gross sales for Q3 2025 alone, annualizing to $3,468.3B across all sectors. Only $200.4B of that quarterly total (23.1%) is currently subject to state sales tax, meaning roughly three-quarters of reported gross sales are entirely outside the state sales‑tax base. "Double‑digit" estimates rarely incorporate this full dataset.

The Comptroller's Tax Exemptions report also shows $66.79B per year in sales tax exemptions with an implied exempt base of about $1,068.6B. Of this, $27.11B represents items taxed under other law (motor fuels, insurance, motor vehicle sales), while the remaining $39.68B corresponds to genuinely untaxed transactions with an implied base of $634.9B. When added to the current taxable base, the broadened base reaches $1,853.5B.

Step 3: Apply the correct formula

Once the total replacement need is properly defined—$86.6B (property taxes) + $7.08B (franchise tax) + $49.1B (existing state sales tax) = $142.8B—the required rate is a simple division. On the full Q3 2025 annualized gross-sales base: $142.8B ÷ $3,468.3B = 4.12%. The 5% Plan uses 5%, generating $173.4B with a built-in $30.6 billion buffer for downturns, enrollment growth, and emergencies.

Burden by income quintile

Section 2's analysis, built on BLS Consumer Expenditure Survey data for Texas, shows that property tax burdens are sharply regressive when measured as a share of income. The lowest income quintile (households under roughly $30,000/yr) faces a property‑tax burden of about 22.59% of income, while the highest quintile faces a burden of around 2.04%. Middle‑income households in the $30,000–$50,000 range still pay about 10% of income in property taxes.

Under the 5% flat sales tax plan, these burdens fall for most groups. The lowest quintile's effective tax burden drops dramatically because property taxes—which are fixed regardless of income—are replaced by a consumption tax that scales with spending. Since lower-income households spend a smaller absolute dollar amount, they pay less in absolute sales tax, even if their spending-to-income ratio is higher.

Homeowners vs. renters

Owner households carry a higher per‑household property‑tax burden than renters—roughly $8,891 per owner household versus about $2,973 per renter household (indirect passthrough). However, because renters tend to have lower incomes, the burden as a share of income remains high. When property taxes are eliminated and replaced with a proportional sales tax, both groups trade a fixed housing‑linked obligation for a consumption‑based obligation that scales with their ability to spend.

Incremental proposals that focus only on homeowners do not change this structure. Renters continue to face embedded property‑tax costs in their rent, and the indirect burden from commercial property taxes remains in the prices of nearly every good and service they purchase. Only a full replacement of property taxes with a transparent sales tax removes this double burden.

No country or state has fully replaced property taxes with sales tax—yet

Critics frequently cite the fact that no developed country has successfully replaced property taxes with a consumption tax. This is true. Australia's 10% GST and New Zealand's 15% GST both exist alongside local property taxes (council rates). North Dakota voters rejected property tax elimination in 2012 (76.54% NO) and 2024 (63.46% NO). Nebraska's attempt failed in 2024.

However, these precedents share a common feature: none proposed a comprehensive, mathematically demonstrated replacement using the full gross-sales base. North Dakota's Measure 4 had "no funded alternative revenue mechanism." Nebraska's plan used the narrow retail base. The 5% Plan is fundamentally different because it uses the Comptroller's own quarterly data to prove the math works with a substantial surplus—not a speculative projection.

Revenue elasticity and base breadth

Because the broadened sales‑tax base is tied to gross sales rather than just retail consumption, it captures a wide range of economic activity, including intermediate goods, business services, and transactions that never appear in household expenditure data. This breadth makes it less sensitive to shifts in any single sector and more aligned with overall nominal economic growth.

Cross‑validation against BEA data shows that the $3,468.3B gross‑sales figure sits reasonably above Texas's $2,769.8B nominal GDP, as expected given that gross sales count intermediate transactions that GDP nets out. That relationship provides an independent check on the plausibility of the Comptroller's reported base.

Education transition mechanics

Under the proposed plan, the $40.2B state education line item is removed from the state budget and replaced by a dedicated share of the sales‑tax distribution. Schools receive $81.9B annually from the sales tax—$41.7B to replace current school property taxes and $40.2B as a direct transfer of what is now state‑funded education spending. This matches or exceeds TEA's projected FSP revenue for the mid‑2020s, providing a margin for enrollment growth and inflation.

What happens in a downturn?

In a recession, both the surplus‑funded and sales‑tax‑funded approaches face slower revenue growth. The crucial difference is that the 5% Plan has already priced in a $30.6 billion buffer between the revenue generated ($173.4B) and the replacement need ($142.8B). That buffer can absorb a 17.6% decline in gross sales before the plan breaks even—a contraction far exceeding the Great Recession's impact on Texas. Additionally, the $24.8 billion Economic Stabilization Fund provides a further backstop during transitions.

By contrast, a plan that dedicates surplus funds to permanent property‑tax relief has no built‑in buffer. The surplus is the buffer. Once it disappears, policymakers must either reverse the relief, cut other spending, or raise other taxes quickly. History suggests that in such moments, property taxes tend to rebound, leaving taxpayers worse off than if the underlying tax structure had been reformed.

Elimination vs. relief

The core distinction between the 5% Plan and the competing proposals is elimination versus relief. Incremental plans shave pieces off a property‑tax bill under favorable fiscal conditions, then depend on future Legislatures to maintain that generosity. The 5% Plan strikes the property tax from the code entirely and replaces it with a single well‑defined levy on transactions, so the debate shifts from "how much relief this session" to "how to manage one tax responsibly over time."

Transparency and accountability

A system where every dollar of state and local general revenue flows from one visible tax on transactions is easier for citizens to understand and for legislators to defend. Exemptions, carve‑outs, and overlapping levies become unnecessary. The current system has 253 Central Appraisal Districts, thousands of taxing entities with different rates, complex FSP formulas with recapture ("Robin Hood"), and an appraisal litigation industry. The 5% Plan replaces this with one rate, one base, one collection mechanism.

Equity across households

Because the sales‑tax burden scales with spending, households that consume more pay more in absolute dollars. By contrast, a property tax tied to assessed value rather than income or expenditures can impose high fixed burdens on households with modest or fixed incomes. Using the same household‑expenditure data that underpins Section 2, the 5% Plan yields net annual savings for the average household even after accounting for higher sales‑tax payments, and the savings are largest in percentage terms for the lowest‑income groups.
