New construction in Texas carries a tax and HOA burden that catches most buyers off guard. Property tax rates across major metro counties range from 1.8% to 2.5% of assessed value, and builder-community HOAs regularly run $150 to $400 per month before special assessments kick in. The real problem is timing: your first full tax bill arrives 12 to 18 months after closing, based on the completed home’s value rather than the lot price you originally signed on.
New Build Tax and HOA Rates in Texas
- Property tax rate: Texas averages 1.60% to 1.80% of assessed value, but new construction homes face full market-value assessments from day one with no grandfathered homestead cap in year one.
- MUD tax add-on: Many master-planned communities sit inside Municipal Utility Districts that add 0.50% to 1.50% on top of the base county rate, pushing effective rates above 3% in some subdivisions.
- HOA dues range: Typical Texas new build HOAs run $150 to $400 per month depending on amenities, with master-planned communities averaging $200 to $350 monthly.
- Worth noting: A $400,000 new build in a MUD with a 3% effective tax rate and $250 monthly HOA adds roughly $15,000 per year in non-mortgage overhead before you factor in insurance.
New Build Overhead by Price Tier
- Entry-level builds: A $300,000 home in a MUD district typically carries $7,500 to $9,000 in annual property taxes plus $150 to $200 per month in HOA.
- Mid-range builds: At $500,000, expect $12,500 to $15,000 in yearly taxes and $250 to $350 monthly HOA, especially in master-planned communities with amenity packages.
- Down payment effect: Your down payment does not change the tax bill, but putting less down means higher monthly escrow payments stacked on top of a larger mortgage.
- Break-even: Buyers who budget only for mortgage principal and interest routinely miss 30% to 40% of their actual monthly housing cost in high-tax Texas MUD and PID communities.
Tax Exemptions and HOA Reductions
- Homestead filing: Texas homestead exemption removes $100,000 from your school district taxable value, saving roughly $1,300 to $1,500 per year on a typical new build.
- Veteran disability: A 100% VA disability rating eliminates property tax entirely in Texas. Partial ratings from 10% to 90% qualify for $5,000 to $12,000 in additional exemptions.
- Ag rollback risk: New subdivisions carved from agricultural land trigger rollback taxes covering up to five years of deferred payments, and builders sometimes pass that cost to buyers at closing.
- Main takeaway: Miss the April 30 homestead filing deadline after your first January 1 as owner and you lose $1,300 or more in savings for the full year with no way to reclaim it.
Real-World Texas New Build Cost Examples
- New build scenario: A $450,000 home in a Fort Worth MUD with a 2.8% effective tax rate and $175 monthly HOA pushes non-mortgage overhead to $1,225 per month.
- Year-two tax jump: Your first bill reflects only lot value if the home wasn’t complete by January 1, so the second year jumps 40% to 60% when full improvement hits the rolls.
- Homestead filing payoff: Filing homestead exemption on a $425,000 new build in Bexar County saves about $1,500 per year on the school district portion and caps future appraisal increases at 10%.
- Bottom line: Buyers who rely on the builder’s estimated taxes in marketing materials typically underestimate their actual first full-year tax bill by $2,000 to $4,000.
How do property taxes work on new construction in Texas?
Texas appraises every property based on its condition as of January 1st. If your new build closes mid-year, the county taxes the land value first, then reassesses the finished home the following January. That first full-year bill often shocks buyers because it reflects the completed structure’s full market value, not the partial-year amount.
Do HOAs pay property taxes in Texas?
No, HOAs do not pay property taxes on your behalf. You receive your own tax bill from the county appraisal district based on your property’s assessed value as of January 1st, and HOA dues are a separate monthly cost covering shared amenities, landscaping, and community upkeep.
What triggers a property tax reassessment in Texas?
Texas appraisal districts reassess every property as of January 1 each year based on its condition and completion status on that date. New builds that close mid-year get a partial first-year tax bill, then face a full-value reassessment the next January 1, which often doubles or triples the amount.
The Bottom Line Up Front
Texas new construction buyers routinely underestimate their real carrying costs. Property taxes on a new build are assessed at full improved value, not the lot price you saw at contract, and HOA dues in master-planned communities often start low then increase as amenities come online. The gap between the builder’s quoted monthly payment and your actual Year Two costs can exceed $500 per month.
Texas appraisal districts assess new construction as of January 1 each year. If you close in March on a $380,000 home, your first tax bill covers only the land value. The following January, the appraisal jumps to full market value and your escrow payment adjusts accordingly. Meanwhile, HOA fees in communities across Williamson County or Fort Bend County MUDs layer on $150 to $350 per month, with annual increases of 5% to 10% common during the first five years as pools, parks, and clubhouses finish construction.
- Your first tax bill on a new build reflects land value only, not the finished home.
- Expect escrow to jump 40% to 60% after the first full January 1 reassessment.
- MUD taxes in new Texas subdivisions add 0.50% to 1.50% on top of the base county rate.
- Builder-quoted HOA dues typically reflect Year One rates before amenity buildout increases kick in.
- Run your own numbers using the county appraisal district site and the HOA’s actual budget, not the builder’s estimate.
Two Mini Tools for New Build Taxes and HOA Overhead
Two quick calculations separate informed buyers from surprised ones at closing on a Texas new build. Run your county’s effective property tax rate against the builder’s projected appraisal value for year-one taxes, then stack the HOA’s published fee schedule against its actual reserve fund balance. Most new builds sit inside MUD boundaries that layer 0.5% to 1.5% in additional taxes on top of base county rates.
| Fee Category | Typical Monthly Cost | Annual Total | Key Verification Step |
|---|---|---|---|
| Base Property Tax (county + school) | $350–$650 | $4,200–$7,800 | County appraisal district rate sheet |
| MUD Tax (if applicable) | $150–$450 | $1,800–$5,400 | MUD bond schedule and payoff timeline |
| HOA Base Assessment | $125–$300 | $1,500–$3,600 | Current HOA budget and meeting minutes |
| HOA Capital Improvement Fee | $40–$125 | $480–$1,500 | Sunset clause or permanent obligation |
| Transfer / Initiation Fee | One-time: $250–$1,500 | One-time | Builder vs. HOA responsibility |
| Special Assessment Risk | $0–$200+ | Varies by levy | Reserve study percentage funded |
Pull your subdivision’s MUD tax rate from the county appraisal district website and add it to school district and city rates for the complete effective number. Compare that total against the builder’s printed estimate sheet line by line. A gap of just 0.3% on a $350,000 home adds $1,050 per year the builder’s payment worksheet never included. On the HOA side, request the current reserve study before you sign the purchase agreement. An HOA carrying reserves below 40% of projected replacement costs frequently levies special assessments within three to five years of the community’s first closings.
Why Texas New Build Taxes Feel Unpredictable?
Texas new build taxes feel unpredictable because the county appraises your home at full completed value on January 1, not at the lot price shown during construction. A $375,000 purchase in June might carry a partial-year bill based on vacant land. The following January, the appraisal district reassesses with the finished structure, and the full-year bill can double or triple.
A buyer closes on a $375,000 new build in Williamson County in June 2026. The first tax bill covers roughly six months of lot-value assessment: about $2,900. The next January, the appraisal district values the completed home at $385,000. At the county’s effective tax rate near 2.18%, the full-year bill runs approximately $8,400. That $5,500 jump hits in year two, right when HOA assessments also start ramping up.
Builders often reference that partial-year figure during the sales process because it looks manageable against the monthly mortgage payment. The actual number is the full-year bill calculated on the finished home’s appraised value, and it does not appear until the second tax cycle. Before signing a new build contract, request the builder’s estimated completed-home value and multiply it by the county’s current effective tax rate. That math takes two minutes and prevents a $400 to $500 monthly escrow shortage from catching you off guard when your lender adjusts the payment in year two.
How Property Taxes Work on New Construction in Texas
Once the county locks your appraised value on January 1, the rest of the tax calendar runs on fixed deadlines. The appraisal district mails your notice of appraised value by April. You have until May 15 to file a protest. Tax bills from every overlapping entity (school district, county, city, MUD, or other special districts) arrive in October and are due by January 31.
| Month | What Happens | Your Action |
|---|---|---|
| Closing day | Builder’s tax proration based on lot or partial-build value | Note this estimate covers only the current tax year at pre-completion value |
| January 1 (next calendar year) | County assesses home at full completed market value | No action required; assessment is automatic |
| April | Appraisal district mails notice of appraised value | Compare appraised value to your purchase price and recent comps |
| April 30 | Homestead exemption filing deadline | File Form 50-114 with your county appraisal district |
| May 15 | Protest deadline for appraised value | File if appraised value exceeds your market evidence |
| October | Tax bills mailed from all taxing entities | Budget for the full amount; due January 31 |
Builder estimates at closing rarely account for the full assessed value. File a homestead exemption application with your county appraisal district as soon as you close, because that $100,000 school district reduction saves $1,000 to $1,200 annually at typical Texas rates. If the appraisal comes in higher than expected, protest by May 15. In most Texas counties, over half of residential protests result in a reduced value. Neither step happens automatically for new construction.
Do HOAs Pay Property Taxes in Texas?
No. Texas HOAs do not pay property taxes on your individual lot. Each homeowner receives a separate tax bill from the county appraisal district and pays directly. The HOA only owes taxes on common areas it holds title to, such as a clubhouse or pool facility. Your dues and your property tax bill are completely separate obligations.
- Monthly dues vs. annual taxes: HOA dues fund shared amenities, landscaping, and neighborhood maintenance on a recurring monthly or quarterly schedule. Property taxes are a separate obligation funding county services, school districts, and special districts on an annual cycle.
- Common area tax pass-through: When the HOA owns parcels like the pool, detention ponds, or a clubhouse, it pays property taxes on those specific parcels. That cost gets folded into your quarterly or annual HOA dues assessment.
- Escrow keeps them separate: Your mortgage servicer escrows property taxes independently from HOA dues. You see two distinct line items on your monthly statement, one to the lender and one to the HOA management company.
- MUD and PID add a third layer: Many Texas new builds sit inside a Municipal Utility District or Public Improvement District that levies its own assessment on top of standard county property taxes. This creates a third cost layer beyond HOA dues and base taxes.
What Triggers a Property Tax Reassessment in Texas
Three events trigger a property tax reassessment on Texas new construction: the certificate of occupancy filing, a recorded change of ownership, and any permit-driven improvement after the original build closes out. The appraisal district does not wait until the next January 1 cycle if your home finishes mid-year. They issue a supplemental assessment covering the portion of the tax year between your occupancy date and December 31.
Pull your certificate of occupancy date from the builder’s closing packet and compare it to the appraisal district’s listed “date of completion” on your notice of appraised value. If those dates differ by more than 30 days, file a protest citing the actual CO date as evidence. Districts sometimes use the permit issue date instead of the CO date, which adds months of taxable occupancy you never had to your first-year bill.
Ownership transfers reset your exemption status entirely. The homestead exemption on the builder’s account does not carry over to you at closing, and the appraisal district treats the sale as a new taxable event. File your own homestead exemption application with the county appraisal district as soon as you record the deed. The statutory deadline is April 30 of the following tax year, but filing early locks in the exemption for the current year if you close before January 1. Missing that window means paying the full unexempted rate on a brand-new assessed value for an entire 12-month cycle.
How Much Are Property Taxes on a $350,000 House in Texas?
A $350,000 house in Texas typically carries $5,950 to $7,700 in annual property taxes, depending on the county and any applicable exemptions. That range reflects effective tax rates between 1.70% and 2.20% across major metros. New construction buyers often land near the top because the appraisal district values the completed home with no aged-property discount applied.
- County rate variation: Collin County’s effective rate runs about 1.80%, while Fort Bend County pushes past 2.20%. On a $350,000 home, that gap alone creates a $1,400 annual difference before any special district overlays.
- Homestead exemption: Filing by April 30 of your first full ownership year removes at least $100,000 from the taxable value, which saves roughly $1,700 to $2,200 depending on your county’s combined rate.
- MUD surcharges: Many new build subdivisions sit inside Municipal Utility Districts that add 0.50% to 1.00% on top of the base county rate, pushing the effective tax well above published county averages.
- First full-year shock: Your initial bill covers only the months after closing, so it looks manageable. The second January 1 assessment hits the full completed value, and that bill is the real baseline going forward.
The Bottom Line
Texas new build taxes come down to one fact most buyers miss: the county appraises your home at full completed value on January 1, not at the contract price you signed during construction. That gap between what you paid and what the appraisal district records is where the sticker shock lives. Running your county’s effective tax rate against the builder’s projected appraisal value before you close gives you a realistic monthly number, not the lowball estimate on the builder’s worksheet.
HOAs add a separate layer of cost but do not pay your property taxes for you. Each homeowner gets a bill directly from the county. Three events trigger reassessment on new construction: the certificate of occupancy, a recorded ownership change, and any permit-driven improvement after the original build. Knowing those triggers and the protest deadline in May puts you in control of the number that actually hits your escrow.
Frequently Asked Questions
How much are property taxes on a $350,000 house in Texas?
The average effective property tax rate in Texas runs between 1.60% and 1.80%, putting the annual bill on a $350,000 home at roughly $5,600 to $6,300 before exemptions. File a homestead exemption and you reduce the taxable value by $100,000 for school district taxes, saving approximately $1,200 to $1,500 per year depending on the district rate. Rates vary significantly by location. Fort Bend County averages closer to 2.2%, while Bexar County sits near 1.9%. MUD taxes in master-planned communities can add another 0.50% to 1.00% on top of those base rates.
How do I look up property taxes by address in Texas?
Start at the county appraisal district website for the property’s county. Every Texas county has an appraisal district with a free online search tool where you enter the property address or owner name. The results show current appraised value, taxable value, exemptions on file, and the tax rate breakdown by jurisdiction (school, city, county, MUD, and special districts). The Texas Comptroller maintains a directory of all 254 county appraisal districts at comptroller.texas.gov. For new construction, check whether the property shows the full completion value or is still reflecting the partial construction-year assessment.
How are property taxes calculated in Harris County?
Harris County uses the Harris County Appraisal District (HCAD) to set property values each January 1. Your tax bill equals the appraised value minus exemptions, multiplied by the combined rate for all overlapping jurisdictions. In Harris County, total rates typically run between 2.0% and 2.8% depending on your city, school district, and any MUD overlay. A home appraised at $400,000 with a homestead exemption might carry a taxable value around $300,000 for school taxes, producing a school tax portion near $3,600 at a $1.20 per $100 rate, plus county, city, and district taxes layered on top.
How do I search property tax records in Katy, TX?
Katy straddles three counties: Harris, Fort Bend, and Waller. Your search depends on which county your specific property falls in. For Harris County, use the HCAD website. For Fort Bend County, use the Fort Bend Central Appraisal District (FBCAD). For Waller County, use the Waller County Appraisal District site. Enter the property address to see appraised value, exemptions, and current tax rates. This matters for new builds because Fort Bend and Waller County portions of Katy often carry different MUD rates than the Harris County portion, and total tax rates can differ by 0.50% or more between adjacent subdivisions.
What is Truth in Taxation in Harris County?
Truth in Taxation is a Texas state law requiring local taxing units to notify property owners when they propose a tax rate that would generate more revenue than the prior year. In Harris County, the county, city of Houston, school districts, and special districts must each publish proposed rates and hold public hearings before adopting increases above the no-new-revenue rate. If a taxing unit’s proposed rate exceeds the voter-approval rate (formerly called the rollback rate), voters can petition for an election to reject it. For new build buyers, this process determines whether your tax rate stays flat or climbs in years after purchase.
What are common complaints about new build taxes and HOA fees in Texas?
Three surprises dominate buyer complaints. First, the first full-value tax bill can jump 40% to 60% over the partial-year bill from the construction period, because the appraisal district reassesses at full completion value the following January 1. Second, HOA fees often escalate after the builder transfers control to homeowners, sometimes by $50 to $150 per month. Third, MUD taxes in master-planned communities add 0.50% to 1.00% on top of base property tax rates. Buyers in communities around Katy, Cypress, and New Braunfels frequently report total monthly costs $400 to $800 higher than their original estimates.
What is the Texas Reality Check tool?
Texas Reality Check is a free online budgeting tool from the Texas Comptroller’s office. You pick a Texas city, set lifestyle preferences for housing, transportation, food, healthcare, and taxes, and the tool calculates the annual salary you need to cover those expenses. It is especially useful for buyers relocating from out of state who need a realistic picture of total living costs beyond just the mortgage payment. The tool does not calculate property taxes on a specific address or estimate HOA fees, but it provides a solid baseline for understanding whether a Texas move fits your income.
