Capstan Tax Strategies vs AE Tax Advisors
Capstan Tax Strategies and AE Tax Advisors compared on cost segregation methodology, tangible property regulations work, energy incentives, pricing model, and who each firm is built to serve.
The Short Version
Capstan Tax Strategies is a specialty tax engineering firm with unusually strong depth in the tangible property regulations, and it works primarily alongside CPA firms rather than directly replacing them.
AE Tax Advisors is the CPA-side firm in that equation: strategy, structuring, filings, and returns, with cost segregation performed as part of the engagement.
If your CPA needs a technical partner for a complex repair-versus-capitalization analysis or an energy incentive study, Capstan is excellent. If you need the advisor rather than the technical partner, that is a different role.
Who Capstan Tax Strategies Is
Capstan Tax Strategies is based in Jenkintown, Pennsylvania and focuses on engineering-driven specialty tax work: cost segregation, tangible property regulations consulting, and energy incentives under Section 179D and Section 45L.
The firm is best known for its depth on the tangible property regulations, the framework in Reg. 1.263(a)-3 that determines whether spending is a deductible repair or a capitalized improvement. That analysis is genuinely difficult, it moves large dollar amounts, and it is the kind of work most generalist firms avoid.
Capstan's model is largely to serve CPA firms as a technical resource. Accountants bring them in for the engineering analysis and retain the client relationship and the filings. That is a well-designed model, and it means Capstan is not trying to be your tax advisor.
Who AE Tax Advisors Is
AE Tax Advisors is a strategic tax advisory firm based in Billings, Montana, working with clients nationwide. The practice centers on business owners, real estate investors, and high-income professionals who have outgrown compliance-only accounting.
The model is deliberately different from a study-only provider. A cost segregation study is one deliverable inside a broader engagement that also covers the passive activity analysis under IRC Section 469, material participation documentation, Form 3115 catch-up filings, entity structuring, reasonable compensation, retirement plan design, and the tax returns themselves.
Pricing is published rather than quoted case by case: $7,800 for the strategic advisory engagement, $2,500 per amended year, $1,500 and up for entity returns, $1,000 and up for individual returns, and $1 per square foot with a $2,000 minimum for cost segregation studies.

Which One Should You Choose?
Choose Capstan Tax Strategies if your CPA needs a specialist for a complex repair-versus-capitalization question, a large renovation, or an energy incentive study, and you want to keep your existing tax relationship intact.
Choose AE Tax Advisors if you want a firm that does the planning, the structuring, the filings, and the returns, and treats the study as one part of that rather than the product itself.
These are not mutually exclusive. Plenty of clients use a specialist for the engineering work on a complex asset and AE Tax Advisors for the strategy, the filings, and the return. We are glad to work from someone else's study.
Why Clients Choose AE Tax Advisors
- The deduction is analyzed before the study is sold. A large depreciation deduction is worth nothing if the passive activity loss rules suspend it. Every engagement models material participation, basis, at-risk, and the excess business loss limitation before a study is recommended.
- The filing is handled, not handed off. Form 3115 with its Section 481(a) adjustment, the duplicate Ogden copy, partial disposition elections, and the depreciation schedules all get prepared in-house.
- Prior years get reviewed. Every engagement opens with a three-year lookback. Recovering overpaid tax from returns already filed frequently covers a meaningful part of the engagement fee.
- Pricing is published. You can compare the cost against the modeled benefit before committing.
How to Evaluate Any Provider, Including Us
Whichever firm you engage, these six questions separate a defensible engagement from a report that will not hold up. Ask them of Capstan Tax Strategies, ask them of us, and compare the answers rather than the marketing.
- Ask which method the study uses. There are several accepted approaches and they are not equivalent. The IRS Cost Segregation Audit Techniques Guide treats the detailed engineering approach, using construction documents and a site inspection, as the most reliable. Ask directly whether someone will inspect the property and review the drawings, or whether the allocation is modeled from photographs and public data. Both are permissible. Only one is easy to defend.
- Ask who runs the passive activity analysis. This is the question that decides whether the deduction is worth anything this year. A study can produce a $400,000 first-year deduction that is entirely suspended under IRC Section 469. Ask who is confirming that you materially participate, that your average period of customer use is what you believe, and that you clear the basis, at-risk, and excess business loss limits. If the answer is nobody, the study is a number on paper.
- Ask who prepares the Form 3115. If you have owned the property for more than a year without a study, the catch-up runs through a change in accounting method rather than an amended return. That means a Form 3115, a Section 481(a) adjustment, a duplicate copy filed with the IRS in Ogden, and often a late partial disposition election. Study providers generally do not prepare it. Confirm who will.
- Ask what happens if the study is examined. Audit support means different things. Ask whether the provider will produce the workpapers, respond to an information document request, and stand behind the allocation, and whether that is included or billed separately. Ask how many of their studies have been examined and what happened.
- Ask for the exit math, not just the year-one number. Accelerated depreciation on personal property is recaptured as ordinary income under Section 1245 when you sell. If you deduct at 35% and recapture at 37%, you have borrowed from the IRS at a negative spread. A provider who only shows you the first-year deduction is showing you half the picture. Ask for the modeled outcome over your actual holding period, including whether a 1031 exchange or a step-up at death is part of the plan.
- Compare total cost, not study cost. A cheaper study plus a CPA who does not understand Section 469 is not cheaper. Add up the study, the return preparation, the Form 3115, and the planning work, then weigh that against the modeled after-tax benefit over your holding period. That is the only comparison that means anything.
Frequently Asked Questions
Is AE Tax Advisors better than Capstan Tax Strategies?
They occupy different positions. Capstan is a specialty engineering firm that serves CPA firms as a technical partner, with unusual depth on the tangible property regulations. AE Tax Advisors is the advisory firm that would engage a partner like Capstan on a complex asset. On a straightforward property, AE Tax handles the study directly.
What are the tangible property regulations and why do they matter?
They are the rules in Reg. 1.263(a)-3 determining whether spending is a deductible repair or a capitalized improvement, using a betterment, adaptation, and restoration framework plus safe harbors. On a large renovation the distinction can move hundreds of thousands of dollars between an immediate deduction and a 39-year schedule.
Does Capstan work directly with property owners?
Capstan's model centers on serving CPA firms, though owners do engage them. If you do not have a CPA handling the strategy, a study alone leaves the passive activity analysis, Form 3115, and return preparation unaddressed.
Can AE Tax Advisors handle 179D and 45L energy incentives?
We evaluate whether they apply and coordinate a qualified provider for the certification work, which requires specific modeling and, in some cases, prevailing wage and apprenticeship compliance. We do not perform the certification in-house, and Capstan is a genuinely strong option for that piece.
Can I use a specialist firm for the study and AE Tax Advisors for the strategy?
Yes, and that is a common arrangement on larger or unusual properties. We regularly work from a third-party engineering report, prepare the Form 3115 and depreciation schedules, run the passive activity analysis, and file the returns. The study and the strategy do not have to come from the same place.
Does a cheaper cost segregation study mean a worse outcome?
Not necessarily, but the method matters more than the price. The IRS Cost Segregation Audit Techniques Guide identifies the detailed engineering approach as the most reliable. A study without site work or construction document review is the first thing challenged on examination, particularly on specialty systems and site improvements.
