Deep analysis with clear strategy
Welcome
Most accountants focus on filing forms.
I focus on diagnosing and repairing tax systems.
As The Tax Mechanic, I help business owners, investors, and professionals identify problems, repair broken financial structures, and build systems that reduce taxes and improve clarity.
Understanding those differences is where strategy lives.

Specialty Areas

When structured correctly, aircraft can behave similarly to real estate inside the tax code creating powerful planning opportunities.
Aviation and Aircraft Ownership
Few accountants have real-world aviation experience. Bob spent 20 years as an international corporate jet captain, giving him a unique understanding of aviation operations and aircraft economics.
Advisory areas include:
-
Aircraft ownership structures
-
Depreciation strategies
-
Leaseback structures
-
Business aircraft usage planning
-
Tax considerations for aircraft investors
Aircraft ownership involves more than acquisition price owners must manage fixed costs, variable operating costs, and maintenance reserves over the life of the aircraft.
Good aviation operations follow a simple principle: aviate, navigate, communicate. Financial structures around aircraft ownership benefit from the same disciplined approach.
Collector Cars and Automotive Assets
At car shows across the country, collectors often ask the same question:
"Is my car hobby, an investment, or a business?"
The answer affects taxes dramatically.
Areas of guidance include:
-
Collector vehicle tax considerations
-
Restoration cost treatment
-
Capital gain vs hobby rules
-
Collector asset tracking
-
Structuring automotive activities


Real Estate and Asset Investors
Many investors accumulate assets without building the structure around them.
Strategic areas include:
-
Depreciation planning
-
Real estate investor tax strategy
-
Asset entity structure
-
Income layering strategies
-
Portfolio tax efficiency
When structured correctly, assets operate as coordinated financial systems rather than isolated investments.

Think of tax planning like maintaining a high-performance machine.
