Deloitte Tax vs AE Tax Advisors for High-Income Clients
Deloitte Tax and AE Tax Advisors compared for high-income individuals and business owners: scale, service model, real estate and depreciation strategy, pricing, and realistic fit.
The Short Version
Deloitte is the largest professional services organization in the world, and its tax practice serves multinationals, funds, and substantial private wealth.
AE Tax Advisors serves owners, investors, and high-income professionals directly, with published pricing and a strategy-first model.
The comparison is less about quality than about instrument fit. Both do good work; they are built for different problems.
Who Deloitte Tax Is
Deloitte Tax provides business tax, international tax, transfer pricing, mergers and acquisitions, indirect tax, and private wealth services globally. Its technology and process infrastructure for large-scale compliance is a genuine differentiator at enterprise scale.
For a company operating in many jurisdictions, a fund with complex waterfalls, or a family with substantial multi-generational structures, that infrastructure solves problems smaller firms cannot.
For an individual owner or investor, the same infrastructure is overhead. The strategies that move the needle at that level, cost segregation with a proper Section 469 analysis, entity selection, reasonable compensation, cash balance plan design, are well within the reach of a focused practice, and get more attention there.
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.

Where Deloitte Tax Is Strong
- Greatest depth and global reach available
- Enterprise-grade compliance infrastructure
- Full service across audit, consulting, and tax
- Institutional credibility for the largest mandates
Where the model has limits
- Engagement minimums far above individual client needs
- Individual real estate and owner strategy is not the focus
- Formal processes slow simple planning questions
Which One Should You Choose?
Choose Deloitte Tax if you operate across jurisdictions, manage a fund, or hold family wealth structures where global depth and institutional credibility are requirements.
Choose AE Tax Advisors if your plan turns on depreciation strategy, entity structure, retirement plan design, and passive activity treatment, and you want direct access and published pricing.
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 Deloitte Tax, 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 Deloitte Tax?
For enterprise and cross-border work, no. For individual owners and real estate investors, AE Tax Advisors is purpose-built for that work and Deloitte is not organized around it. The right answer depends entirely on the complexity of what you are solving.
Would Deloitte take me as a client?
Possibly, through a private client practice, but engagement minimums are substantial and an individual property strategy is not what the practice is designed to deliver. Many high earners find the scope and cost poorly matched to their actual needs.
Who is better for a short-term rental strategy?
A focused firm, in almost every case. The strategy depends on the seven-day average customer use test, material participation documentation, and a cost segregation study, and it needs someone monitoring those facts during the year rather than reviewing them at filing.
Can a smaller firm defend an IRS examination?
Yes. Representation before the IRS requires a CPA, enrolled agent, or attorney, not a particular firm size. What matters is the quality of contemporaneous documentation supporting the position, which is built during the year the position is taken.
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.
