Sector choices: what changes the decision?

Medical practice: favour evidence of partner-level and employee-level analysis when retirement or ownership is involved. A practice-wide number can hide different cash obligations. Cash balance plans are defined benefit arrangements; obtain design and funding input before treating the proposal as optional annual saving.

Contractor: favour contract-method, cash and financing competence. Require the adviser to distinguish tax reporting from management and lender reporting. Current IRS method-change guidance discusses construction contracts, so a generic promise to switch methods is not adequate. IRS — Internal Revenue Bulletin 2026-39: Accounting method guidance

Agency: distinguish business structure, owner-payroll work, state complexity and an ownership event. An LLC and S corporation are not mutually exclusive legal alternatives; compare the actual tax classification and its consequences. IRS — Entities 3: LLC tax classification
