S Corporation Owner Tax Planning Worked Example
Practical guidance for business owners and residential rental investors.
Hypothetical planning example
This page is an educational worked example. It does not represent a verified AE client outcome.
Worked example: wages, reimbursements and retirement are separate
A hypothetical consulting S corporation reviews owner compensation, eligible expense reimbursements and a retirement plan. Each requires its own analysis. Wages must reflect reasonable compensation; reimbursements require actual eligible expenses and substantiation; retirement contributions depend on the plan and relevant limits.
Illustrative decision
The company cannot count the same $10,000 expense once in operating costs and again as a reimbursement saving. Likewise, a retirement contribution is a funding commitment, not free cash. A combined projection should reconcile deductions, payroll, cash outflows and the owner's return without stacking overlapping benefits.
Measure owner cash after implementation costs
Use the same profit assumptions before and after the proposed changes. Include compensation, payroll, contribution funding and separately priced professional work. Explain which deductions reflect actual spending, which change timing and which depend on eligibility. Avoid adding overlapping tax estimates. Retain the assumptions so the result can be revised when actual wages or profits differ.
What this example does and does not establish
The facts and numbers on this page are hypothetical teaching inputs. They are not a verified client result, a filed-return outcome or a prediction of typical savings. An actual engagement requires source records, applicable-year analysis and a final return reconciliation. No individual professional review is claimed. Cost segregation and other project work are separately scoped from advisory.
Records and decisions to prepare
- Document compensation responsibilities and market support
- Reconcile reimbursements with existing expenses
- Confirm employee and plan eligibility
- Model funding and payroll costs
- Compare combined after-tax cash using explicit assumptions
