Compare 10 cost segregation Texas firms for 2027, from Houston and Dallas specialists to national CPA firms with Texas offices, plus pricing and owner fit.
Texas investors own everything from Austin short-term rentals to Houston medical buildings and Dallas-Fort Worth warehouses, and cost segregation can speed up depreciation on all of them. This list is for Texas property owners, syndicators and CPAs looking for a firm to run a Texas cost segregation study, whether you need cost segregation Houston owners can get locally or cost segregation Dallas investors can get from a DFW office. If you need a primer, read our guide on how cost segregation works.
Every firm here has a Texas office or a clearly documented Texas track record, and we say which for each. We also looked at methodology, audit support and pricing transparency, and mixed national specialists, Texas-based firms, CPA firms and a flat-fee remote provider. For cost segregation Texas investors should remember one local detail: Texas has no personal state income tax, so for most individual owners the benefit is entirely federal. Cost segregation also does not lower your local property tax bill.
The federal rule that matters most in 2027: under the One Big Beautiful Bill Act, signed July 4, 2025, 100% bonus depreciation is permanent for qualifying property acquired and placed in service after January 19, 2025. Property acquired on or before that date stays on the old phase-down, which reaches 0% for property placed in service in 2027. Confirm how this applies to you with your CPA.

3. Source Advisors — Arlington-Based Studies From An ASCSP-Certified Team
Source Advisors lists its office at Woodland Park Boulevard in Arlington, in the middle of the Dallas-Fort Worth market. It cites more than 40 years in the cost segregation industry. Texas presence: office.

Its building types include hotels, medical offices and clinics, data centers, distribution centers, manufacturing, retail and self-storage. A typical study takes about eight weeks, and Source Advisors says it helps clients if the IRS audits their property.
Its intake asks whether the building or renovation cost exceeds $500,000, so it fits mid-size and larger commercial properties best.

How To Choose A Cost Segregation Firm In Texas
Do You Need A Local Office?
For residential rentals and small commercial buildings, a remote study prepared from documents and a virtual walkthrough is usually enough. For large or complex properties, a firm with a Texas office can send someone on site more easily. Ask each firm how it handles inspections for your property type.
Ask who prepares the study, whether it follows IRS guidance, and what audit support is included and for how long.
Does The Fee Make Sense?
Prices range from a few hundred dollars for a remote residential study to custom quotes for large commercial buildings. Ask for a benefit estimate first, and compare quotes on scope, audit support and turnaround as well as price.
Frequently Asked Questions
Does Cost Segregation Lower Texas Property Taxes?
No. Cost segregation affects federal income tax depreciation. Property taxes are set by your county appraisal district, and lowering them requires a separate protest or appeal.
Is There A Texas State Benefit From Cost Segregation?
Texas has no personal state income tax, so for most individual investors the benefit is federal only. Businesses subject to the Texas franchise tax should ask their CPA how depreciation affects that calculation.
Does 100% Bonus Depreciation Apply In 2027?
Under the 2025 law, qualifying property acquired and placed in service after January 19, 2025 is eligible for permanent 100% bonus depreciation. Property acquired earlier follows the old phase-down, which is 0% for property placed in service in 2027.
Can I Study A Property I Bought Years Ago?
Yes. A look-back study claims missed depreciation in the current year through a change in accounting method on Form 3115, without amending earlier returns. Your CPA should confirm eligibility.
Conclusion
Texas owners have plenty of choice. KBKG, Engineered Tax Services and Source Advisors bring specialist depth with Texas offices, Weaver, Forvis Mazars and Haynie suit owners who want a CPA firm, O’Connor pairs studies with property tax work, and R.E.
