Where structural tax inefficiencies actually hide.

When owners ask where they are overpaying, they usually look at deductions. Did I claim the home office. Did I write off the vehicle. Did I capture every meal. Those numbers matter at the margin, but they are not where the meaningful money lives. The meaningful money lives in structural decisions that were made years ago and never revisited.

Entity choice and the ownership stack.

An S corporation that should have a holding company above it. An LLC taxed as a partnership when an S election would have eliminated tens of thousands in self-employment tax. A single entity holding both the operating business and the real estate it sits on. These are not exotic problems. They are common, and each of them silently overpays for years.

Compensation and the reasonable salary line.

Owner compensation is one of the most-modeled, least-optimized numbers in a small business. Set too low, it invites scrutiny. Set too high, it gives away payroll tax that did not need to be paid. The right number is defensible, documented, and modeled against the rest of the architecture, not picked because last year's number was close enough.

Asset location and the after-tax return.

A portfolio that looks identical on a brokerage statement can produce wildly different after-tax outcomes depending on which account holds which asset. Tax-inefficient income in a Roth. Tax-efficient growth in a taxable account. It is the same investments, in the wrong places, and the drag compounds for decades.

The boring middle of the return.

• Depreciation methods chosen by default rather than designed.
• Accountable plans that were never written, so reimbursements became taxable wages.
• Retirement plan choices that fit five years ago and have not been revisited.
• Multi-state filings missing elections that would have lowered the home-state liability.
• Charitable strategies that route through cash when appreciated assets would have done more work.

Each one is small in isolation. Together, in a single architecture, they often add up to the largest line item the owner did not know they were paying. A real review surfaces them. A filing engagement does not look.

“The expensive mistakes are almost never on the line you are looking at. They are in the structure you stopped questioning.”
