California → Texas

Overview

The California-to-Texas corridor has been the single largest interstate migration flow in the US for most of the last decade. Per US Census Bureau ACS 2022 migration flows, CA-to-TX net flow was approximately 102,000 individuals. The reasons cluster differently than households often articulate: fire risk and CA insurance market dislocation are the new factors layered onto the longer-running cost-of-living and tax drivers.

What’s actually driving the move

Three forces:

1. Wildfire + insurance market. The CA homeowners market has not been the same since 2017-2018. State Farm General paused new homeowners business in May 2023 and announced non-renewal of approximately 30,000 policies in high-risk ZIPs by 2024-03. Allstate paused new CA homeowners business in November 2022. Farmers capped new CA homeowners policies in July 2023. The California FAIR Plan — the wildfire-exposed residual market — doubled its policy count between 2020 and 2024 to approximately 555,000 policies per CA DOI testimony. The CA Sustainable Insurance Strategy is the regulatory response (effective phased through 2025), permitting reinsurance and catastrophe modeling in rates in exchange for carrier commitments to write in high-risk zones. That trade is still being absorbed.

2. Cost of living + tax. California top marginal income tax is 13.3% (Tax Foundation 2024); Texas is 0%. On a household income of $250,000, the headline differential is roughly $25K to $33K per year, before all the wrinkles (TX is not free — the property tax effective rate is 1.68%, third highest in the country). The full math sits in the table on this page.

3. Water + heat. Less commonly cited as a primary driver but accelerating. The Colorado River Lower Basin shortages, the CA SWP allocation cuts, and the Phoenix-AMA new-build freeze are reshaping cost expectations across the entire Southwest. TX is on the eastern edge of that pressure — DFW and Houston have functional water supply, but Austin and San Antonio’s Edwards Aquifer dependence + Hill Country development is a longer-cycle constraint.

Why Texas specifically (vs. the alternatives)

The CA exit doesn’t go only to Texas. ID, AZ, NV, CO, TN, NC, and FL all show meaningful CA inflow in Census ACS flows. We focus on TX because:

• Largest absolute volume — partner economics work better at scale.
• Established CA-to-TX professional services infrastructure — moving companies, real estate brokers, mortgage lenders, CPAs already specialize in this corridor.
• Four genuinely different target metros (Austin, Dallas, Houston, San Antonio) with materially different climate exposure + cost profiles, so a single corridor playbook serves multiple lifestyles.

The four target metros

Austin-Round Rock-Georgetown. Tech + remote-work magnet; closest to CA in lifestyle. Median home price approximately $444K (Zillow ZHVI 2024-Q4). Extreme heat exposure (49 days/yr ≥95°F per NOAA NCEI 1991-2020 normals) is the underrated factor. Drought + water-stress score elevated; Edwards Aquifer dependence is structural.

Dallas-Fort Worth-Arlington. Largest TX metro for CA inbound. Median home price approximately $311K. Convective storm / hail is the dominant insured-loss driver — 18% YoY premium increases 2023-2024 per Texas Department of Insurance market data. Tarrant + Collin counties are the heaviest absorbers.

Houston-The Woodlands-Sugar Land. Hurricane exposure (Harvey 2017 Cat 4 + Beryl 2024 Cat 1; Harris County is in NHC’s highest landfall-frequency band). Subsidence compounds sea-level rise (Galveston tide gauge: 6.6 mm/yr observed 1908-2023, among the highest in the US). Median home price approximately $271K. Worth the trade for some households; not worth it for households exiting CA fire risk who would just be trading one peril for another.

San Antonio-New Braunfels. Lower CA inbound volume but rising. Median home price approximately $261K. Edwards Aquifer water-supply context matters; SAWS rotates between aquifer and Vista Ridge import. Extreme heat at the Austin level.

What you trade

Honest framing: you are not buying lower climate risk by moving CA → TX. You are exchanging one peril (wildfire, drought) for a different set (extreme heat, hurricane in Houston, convective storm in DFW). Our blended climate risk score for LA versus DFW is roughly comparable in absolute terms — the perils are simply different.

What you are buying:

• A functioning admitted homeowners insurance market (TX availability index 62, versus CA’s 31).
• A 13.3 percentage point reduction in state top marginal income tax (zero-sum against a 0.93 percentage point increase in property tax effective rate).
• A substantially lower median home price across all four target metros (especially DFW, Houston, San Antonio).
• A faster transactional environment — TX real estate closings typically execute in 30-35 days versus CA’s 35-45.

What you should plan for:

• Higher annual property tax bills in absolute terms (because the home value is lower but the rate is higher; the net is often a wash but the structure is different).
• Heat-resilient HVAC + insulation costs you may not have budgeted in CA-coastal context.
• A homeowners insurance premium that is lower than your current CA premium today but rising at TX market rates (~12% YoY currently per NAIC data).

The remaining sub-pages walk through insurance specifics, housing economics, schools (TX is district + charter heavy), healthcare networks, and the 90-day execution checklist.

Schools

TX school structure vs. CA: the key shifts

Texas runs school administration through independent school districts (ISDs) and a robust charter sector. The system differs from CA on three load-bearing dimensions:

1. ISDs are independent taxing authorities. A TX ISD levies its own property tax. The ISD boundary, not the city or county boundary, determines your school + your tax bill. Frisco ISD, Plano ISD, Carroll ISD (Southlake), Eanes ISD (Westlake) are widely-cited names — and the boundaries do not always match the municipal boundary. Diligence requires verifying the specific ISD assignment for the specific address.

2. School ratings are state-published. Texas Education Agency publishes A-F accountability ratings for every campus + district annually. The ratings are heavily weighted on student-achievement and student-growth metrics; they are the de facto comparison framework for inbound CA households who are used to GreatSchools / Niche-style aggregations.

3. Charter networks are large. KIPP Texas, IDEA Public Schools, Harmony Public Schools, Uplift Education, Yes Prep, BASIS Texas — Texas has more charter enrollment than nearly any other state. Application windows typically run November through February for the following August.

By metro

Austin

Top-rated ISDs by inbound CA volume:

• Eanes ISD (Westlake). Smallest but typically top-rated. Heavy zone overlap with high-priced Westlake real estate.
• Round Rock ISD (Round Rock, Cedar Park). Large; serves Williamson + Travis. Strong STEM programs.
• Leander ISD (Cedar Park, Leander, NW Austin). Rapid growth; new schools opening regularly.
• Lake Travis ISD (Lake Travis area). Higher-end suburban district.
• Dripping Springs ISD. Smaller; Hays County.
• Hays CISD (Kyle, Buda). Lower-priced submarket option.
• Austin ISD. Central; mixed performance; magnet specialty programs (Liberal Arts and Science Academy / LASA, Ann Richards School) attract competitive admissions.

Charter inventory. IDEA Public Schools + Harmony + KIPP all operate in Austin. KIPP Austin Public Schools serves PreK-12.

DFW

Top-rated ISDs:

• Carroll ISD (Southlake). Northeast Tarrant County. Highest-ranked DFW district by TEA accountability ratings most years.
• Frisco ISD. Collin County. Rapidly growing; among largest in Texas.
• Plano ISD. Collin County. Long-established academic reputation.
• Allen ISD. Collin County. Heavy CA + Northeast inbound.
• Coppell ISD. Northwest Dallas / Southeast Denton.
• Highland Park ISD. Tiny enclave district inside Dallas; highest-priced real estate; legacy academic reputation.
• Eanes-like exception districts (Northwest ISD, Argyle ISD, Prosper ISD). Smaller; growing fast.

Charter inventory. Uplift Education is the largest DFW charter network; KIPP DFW operates; IDEA DFW; BASIS Texas.

Houston

Top-rated ISDs:

• Katy ISD. West Houston; Fort Bend / Harris boundary. Heavy inbound.
• Fort Bend ISD. South / west of Houston.
• Cy-Fair ISD. Northwest Harris.
• Klein ISD. North Harris.
• Conroe ISD (The Woodlands). Montgomery County. Master-planned-community-aligned.
• Spring Branch ISD. Memorial / west Houston.
• HISD (Houston ISD). Largest TX district; the magnet schools (Carnegie Vanguard, DeBakey HSHP, HSPVA) are nationally competitive but admission is selective.

Charter inventory. Yes Prep + KIPP Houston + IDEA Houston + Harmony.

San Antonio

Top-rated ISDs:

• Alamo Heights ISD. Established academic reputation; small enclave.
• North East ISD. Largest middle-tier district.
• Northside ISD. Largest SA district.
• Boerne ISD (Kendall County). Suburban; rapid growth.
• Comal ISD (New Braunfels area). Hill Country.
• San Antonio ISD. Central; magnet specialty programs (CAST schools, Travis Early College HS).

Charter inventory. IDEA San Antonio is the largest. KIPP SA also active.

Enrollment windows

ISD enrollment for new TX residents typically opens in March-April for the following August. Charter applications close earlier (January-February most networks). For mid-year moves, ISDs are statutorily required to enroll TX residents within 5 school days under Texas Education Code; you fill the address-zoned campus seat or, if at capacity, the nearest open seat with bus transport.

Private school inventory

Private school cycles in TX mirror the Northeast — January applications for August enrollment for the competitive day schools (St. John’s, Kinkaid, Episcopal in Houston; Greenhill, Hockaday, St. Mark’s, Episcopal School of Dallas in DFW; St. Andrew’s, St. Stephen’s in Austin; TMI Episcopal, Saint Mary’s Hall in San Antonio).

Special education + IEP transfer

TX must implement comparable services upon enrollment under IDEA, same as TN. The comparable-services interim period typically runs 30 days. Texas ARD (Admission, Review, and Dismissal) committee replaces the CA IEP team but operates similarly. Pre-arrival documentation handoff is the load-bearing step — request the full CA IEP packet before withdrawal, hand it to the receiving TX ISD before the move date.

529 plans

CA’s ScholarShare 529 is not state-tax-deductible (CA does not offer a 529 income-tax deduction; this is one of three states without one). TX similarly has no state income tax and no 529 deduction. Your 529 plan ports without tax consequence; you may choose to roll into TX’s Texas College Savings Plan (Texas Tuition Promise Fund is the prepaid plan) for state-aligned beneficiary tracking, but it is not required.

What we route

We do not route school placement. Concierge service is the calendar coordination + the ISD-vs-charter shortlist matching + the IEP transfer logistics.

Healthcare

ACA Marketplace households

CA Marketplace coverage runs through Covered California; TX Marketplace coverage runs through the federal healthcare.gov platform. The move triggers a 60-day Special Enrollment Period.

The non-obvious points:

• CA expanded Medicaid under the ACA; TX did not. If your household income falls in the “Medicaid expansion” band (138% FPL or below), you have CA coverage today and will have a coverage gap in TX. Texas Medicaid is restricted to children, pregnant women, parents of dependent children below specific thresholds, and disabled adults. For working-age adults at low income without dependents, there is no TX Medicaid path and the Marketplace subsidies start at 100% FPL, leaving a structural gap. This is relevant for fewer CA-to-TX households than the cost-of-living migration narrative, but it is the most consequential single difference for households where it applies.
• Subsidy recalculation. APTC recalculates on TX income + household. Most CA-to-TX households see comparable or slightly higher subsidy because the TX benchmark plan in many regions is more expensive than the CA benchmark.
• Network reconfiguration. CA and TX provider networks have essentially no overlap. Your CA specialist relationships do not port. The TX Marketplace carrier mix is dominated by Blue Cross Blue Shield of Texas, Ambetter (Centene), Oscar (selective regions), and Molina. The carrier-network footprints differ by region.

Medicare + Medicare Advantage households

Medicare Original ports automatically. Medicare Advantage and Part D do not — the move triggers a 2-month SEP. TX MA market is dominated by Humana, UnitedHealthcare, BCBS of Texas, Aetna, and WellCare. By metro:

• Austin: Strong UnitedHealthcare + Humana presence; Ascension Texas + St. David’s HealthCare are the dominant systems.
• DFW: Most competitive MA market in TX. Texas Health Resources, Baylor Scott & White, HCA Medical City all participate in multiple MA networks.
• Houston: Memorial Hermann + Houston Methodist + HCA Houston Healthcare + MD Anderson (cancer specialty) all have network agreements with multiple MA carriers. MD Anderson network access is the load-bearing variable for oncology households.
• San Antonio: Methodist Healthcare + Baptist Health System + UT Health San Antonio (academic).

For specialty-medication households, formulary matching across the SEP window is the highest-stakes step. Same drug can shift from a Tier 2 to a Tier 4 across plans within the same market.

Employer coverage households

National plans (Cigna, Aetna, UnitedHealthcare, Blue Cross variants) have TX PPO + HMO options. The most common surprise: a CA Kaiser Permanente member moving to TX loses Kaiser entirely. Kaiser does not operate in Texas. CA Kaiser households must select an alternate carrier through their employer’s TX offerings during the relocation SEP — and the alternate carrier’s network typically does not include the specialty-care integration that Kaiser provided. This is one of the most significant single healthcare disruptions in the corridor and frequently catches CA tech-employer households by surprise.

Hospital systems by metro

Austin. Ascension Seton + St. David’s HealthCare are the dominant systems. UT Health Austin (Dell Medical School) is the academic center. Texas Children’s Hospital North Austin is the pediatric specialty option.

DFW. Baylor Scott & White Health (largest TX nonprofit system), Texas Health Resources, HCA Medical City, UT Southwestern (academic; nationally-ranked cancer + cardiology). Children’s Health (Children’s Medical Center Dallas).

Houston. Houston Methodist (academic-affiliated), Memorial Hermann (Level I trauma; large network), Texas Children’s Hospital (one of the top pediatric centers in the US), MD Anderson (cancer; in the Texas Medical Center, the largest medical complex in the world by some measures). Baylor College of Medicine is the academic anchor.

San Antonio. Methodist Healthcare + Baptist Health System + UT Health San Antonio. Children’s Hospital of San Antonio.

Provider transitions

Same sequence as other corridors:

1. Request 12-month records from each CA provider before the move (Sutter, UCSF, UCLA Health, Stanford, Cedars-Sinai have 30-90 day release SLAs).
2. Establish TX primary care + dental within first 60 days, post-insurance-effective-date.
3. Re-establish specialist relationships in acuity order. TX specialist new-patient lead times run 4-12 weeks; book before move if possible.

For oncology + complex specialty households, this corridor has a specific advantage: MD Anderson + UT Southwestern + Baylor College of Medicine are all top-tier referral centers. Sequencing a major treatment transition into Houston specifically often results in better continuity than the CA exit would suggest.

What we route

Marketplace + Medicare navigation routes to a CMS-credentialed navigator partner (status: pending activation). Compensation is per-enrolled-household in the $50-$150 band, disclosed at point of routing. We do not route to specific provider practices.

The concierge service is the SEP enforcement + the network-match diligence: making sure you don’t miss the 60-day Marketplace window or the 2-month Medicare window, and making sure the plan you select actually includes the specialty system (MD Anderson, UT Southwestern) you may need.

The 90-day checklist

The 90-day CA → TX execution checklist

The CA close is the bottleneck — plan around it.

Weeks 1-2: target selection

• Pick the TX metro (Austin / DFW / Houston / San Antonio).
• Identify the ISD or charter school target before the property — TX schools are address-zoned and the ISD determines a meaningful portion of total cost.
• Identify 3-5 candidate properties matching ISD + budget.
• Pre-quote homeowners insurance via TX independent agent for each candidate. For Houston coastal candidates, layer in TWIA wind/hail quote.
• Pre-qualify with mortgage lender holding TX licensing.
• Pull CA property’s preliminary title report, NHD (Natural Hazard Disclosure), and most recent insurance declaration.
• If CA Kaiser household: identify replacement TX carrier through employer or Marketplace.

Weeks 3-4: dual listing + offer

• List CA property (or proceed if already listed). Plan for 45-60 day escrow.
• Make TX offer contingent on CA sale, or with extended contingency window.
• Complete TX property inspection. TX inspections are typically faster than CA but the inspector pool is large and the report standards vary — use the agent referral.
• Complete TX insurance bind quote within contingency window.
• Begin records transfer: school records, medical records, dental records, veterinary records.
• If CA Marketplace household: confirm SEP eligibility documentation (move date will be the SEP trigger).

Weeks 5-6: CA sale prep + TX financing

• Complete CA seller disclosures (TDS, SPQ, NHD).
• Sign CA listing contract amendments as needed.
• Lock TX mortgage rate (60-day lock minimum given CA escrow length).
• Bind TX homeowners insurance effective TX closing date.
• Bind TX auto insurance.
• If applicable, secure storage + interim housing for the CA-close to TX-close gap.
• Order TX utilities (Austin: Austin Energy + Austin Water + Texas Gas Service; Dallas: Oncor/TXU + Atmos Energy + Dallas Water Utilities; Houston: CenterPoint Energy + various REPs in deregulated market; San Antonio: CPS Energy + SAWS).
• Schedule CA utility shut-off.
• Schedule interstate move with FMCSA-licensed carrier (verify USDOT + MC numbers).

Weeks 7-8: closing + transit

• Close CA sale. Confirm wire receipt before vacating.
• Close TX purchase.
• Execute interstate move.
• Cancel CA homeowners + auto policies effective post-CA-close.
• Cancel CA renter’s insurance if applicable.
• If CEA earthquake policy: confirm termination on CA closing.

Weeks 9-10: residency establishment

• Apply for TX driver’s license at DPS within 90 days (TX statutory window).
• Register vehicles with TX county tax assessor-collector. Pass TX safety + emissions inspection (DFW, Houston, Austin, El Paso require emissions; San Antonio + rest typically safety only).
• Register to vote in TX.
• File USPS change-of-address.
• Update IRS address (Form 8822) — important for CA tax-residency severance.
• Update Social Security Administration address.
• Update bank addresses; consider opening a TX-headquartered account at Frost Bank, Texas Capital Bank, or PlainsCapital for convenience.

Weeks 11-12: healthcare + schools + finalize

• Enroll in TX Marketplace plan within 60-day SEP window.
• Or enroll in Medicare Advantage TX plan within 2-month SEP.
• Establish TX primary care provider. Transfer records.
• Enroll children in TX ISD (5-school-day statutory enrollment) or charter (if seat available).
• Confirm IEP transfer if applicable; schedule TX ARD within 30 days.
• File homestead exemption (TX is generous — file in the county within the first year for a meaningful property tax reduction starting the year after filing).

Quarter 2: tax-residency closure

• Document CA move-out + TX move-in dates for FTB partial-year residency.
• Engage CPA familiar with CA-to-TX moves for the partial-year CA Form 540NR + federal-only TX filing.
• If maintaining any CA real property post-move, document non-primary-residence status and tenant arrangement.
• California FTB scrutiny on tax-residency exits is well-documented — the indicia list (CA driver’s license, CA voter registration, CA bank account, CA professional license, CA primary care) all need to flip cleanly to TX. The 183-day rule is the floor; the indicia win the audit if it comes.

Quarter 2-3: optimize the move

• Re-quote homeowners + auto at TX renewal cycle (most carriers offer a multi-policy discount and renewal pricing improves on the second year with TX history).
• Review TX 529 contribution strategy if applicable.
• If high-income, review whether the move-out year was the right year for any deferred-comp recognition, ISO/RSU events, or other CA-source income realizations. (CPA conversation.)

What we do

Weeks 1-2 target selection, week 3-6 insurance + mortgage sequencing, week 11-12 healthcare SEP enforcement. We coordinate the calendar so each licensed professional has inputs on time.

We do not provide tax advice. We do not handle the FTB residency conversation; that is your CPA’s lane. We do route to a CA-TX-specialist CPA partner (status: pending activation) for households who want one.
