An S corporation owner may personally pay a legitimate company expense, but the payment still needs to be recorded correctly. A properly operated accountable reimbursement arrangement generally requires a business connection, timely substantiation, and return of excess advances.

The practical goal is a clear trail: the owner submits an expense report, attaches receipts, identifies the business purpose, and receives the approved reimbursement. Personal expenses cannot become business expenses simply because they appear on that report.

Adopt a process that fits the company and have the preparer review it. Keep reimbursements separate from wages and shareholder distributions. A fixed monthly transfer with no supporting expense report should not automatically be treated as a tax-free accountable-plan reimbursement.

Your next steps

• Ask about a written reimbursement policy.
• Submit receipts and business-purpose details regularly.
• Track advances and return amounts not substantiated.
