Moss Adams vs AE Tax Advisors for Real Estate Tax Strategy
Moss Adams and AE Tax Advisors compared: firm scale, service breadth, typical client size, cost segregation capability, pricing model, and who each is genuinely built to serve.
The Short Version
Moss Adams is a large national accounting and consulting firm serving the middle market, with audit, tax, and advisory under one roof and a specialty tax group that includes cost segregation.
AE Tax Advisors is a focused advisory practice serving individual business owners and real estate investors, with published pricing and direct access to the person doing the work.
The deciding factor is usually scale. If you need audited financial statements, multi-entity consolidations, or international structuring, that is Moss Adams territory. If you need proactive tax strategy on a handful of entities and properties, a large firm's minimums frequently exceed the value delivered.
Who Moss Adams Is
Moss Adams is one of the largest accounting firms in the United States, headquartered in Seattle with offices across the country. It serves middle-market and larger companies with assurance, tax, and consulting services, and maintains specialty groups covering credits and incentives, international tax, transaction services, and cost segregation.
For a company that needs an audit, has institutional investors or lenders requiring assured financials, operates across multiple states or countries, or is preparing for a transaction, the breadth is genuinely valuable. Depth in industry verticals is real, and the firm carries the infrastructure to support complex compliance.
The tradeoff is structural rather than a criticism. Large firms are organized around larger engagements. Work is typically delivered through teams with rotating staff, engagement economics favor clients above certain revenue thresholds, and pricing is quoted per engagement based on scope and hours.
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 Moss Adams if you need audited financials, international structuring, transaction due diligence, or compliance infrastructure for a company of meaningful size.
Choose AE Tax Advisors if you are an owner or investor who wants proactive strategy, published pricing, and direct access to the person building your plan.
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 Moss Adams, 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 Moss Adams?
They serve different client profiles. Moss Adams is built for middle-market and larger companies needing assurance, international, and transaction services alongside tax. AE Tax Advisors is built for owners and investors who want proactive planning without the scale and cost of a national firm. Neither is a substitute for the other.
Does Moss Adams do cost segregation?
Yes, within its specialty tax practice, and it is capable work. The practical question is whether the engagement size fits. A single short-term rental or a small commercial building may fall below the threshold where a national firm can serve you economically.
Do I need a big firm name for my lender?
Sometimes, for audited financial statements or a formal review. For tax planning and return preparation there is generally no such requirement. If your lender requires assurance work, that is a genuine reason to engage a firm like Moss Adams for that specific deliverable.
Can I use both firms?
Yes, and it is a reasonable structure. A large firm handles the audit and complex compliance while a focused advisor drives tax strategy and coordinates implementation. We regularly work alongside a client's existing accounting firm rather than replacing it.
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.
