262 tax planning case studies for business owners and real estate investors. These distinguish documented plans and engagement scopes from completed work, with an additional opportunity to evaluate in each story.

Every documented case study below reflects the kind of work we do: cost segregation and depreciation strategy, entity design, reasonable compensation, retirement plan structuring, pass-through entity tax elections, and prior year recovery. All studies are anonymized, all figures are rounded, and no client names or identifying details appear anywhere. Strategies depend entirely on facts and circumstances and are not universal recommendations. Educational case studies use illustrative facts and figures and do not document specific client results.

New: 12 planning examples with recommendations. Explore rental conversions, partnership cash flow, owner payroll, business exits and more. These anonymized composites explain decisions and required records; they do not claim completed client outcomes.

Find a Case That Looks Like You

Combine filters to match your income, business and property situation. Income means the published income or net profit figure, not business revenue or property value. On illustrative examples, the card explicitly identifies assumed profit. Cases without a published figure remain available under “Income not specified.”

Ownership describes the operating business shown in the case. “No real estate shown” describes the story’s scope; it does not confirm a client has no property.

About these case studies

This collection includes publisher-reported outcomes and educational case studies. Educational case studies use illustrative facts and figures and do not document specific client results. Published dollar amounts may describe deductions or offsets rather than realized savings. The underlying returns have not been independently audited for this website update. Read each page's limitations and evidence standards before interpreting the result.

Review the Firm, the Work and the Scope

AE Tax Advisors reviews and case studies bring together third-party profile information and 28 anonymized planning stories. Compare documented work with your own needs, then confirm deliverables and fees in writing.

Find the best short term rental tax company for your needs — compare STR operating-record review, study coordination, return preparation and implementation support.

Read each scenario with its evidence and assumptions

Identify whether an example is illustrative or documents an actual client engagement. A projected deduction, a proposed plan and a verified realized tax result describe different stages and should be evaluated separately.

Review service scope

Use a scenario to identify questions for your own review rather than copying its conclusions.

Evaluate property economics

Compare the property assumptions, fees, holding period and usable loss in a depreciation example.

Check implementation cost

Include the cost of advisory and any separate tax-return or study work.

Prepare your facts

Build your own record file before asking whether a similar approach applies.

Before engaging an advisor, confirm the entities and tax years covered, the records required, the person responsible for each implementation step and how completion will be documented. Discuss the appropriate review with the AE team.
