Identify who actually holds the company’s debt
An owner signs a guarantee for a bank loan and assumes the loan is equivalent to a shareholder advance. Begin with the documents and money flow. The bank may be the corporation’s lender even though the owner has a contingent obligation under a guarantee. A separate shareholder loan involves its own creditor relationship and funding facts. Have the preparer analyze stock and debt basis using the actual arrangement rather than treating the guarantee amount as a personal contribution by default.
Gather the note, guarantee, security documents, bank statements, company ledger, and any later modifications. Identify whether the owner ever paid the lender or transferred funds directly to the company. The chronological record matters. A payment made after a loss year should not silently appear in a workpaper as though it occurred before the loss arose.
A hypothetical two-route financing decision
Assume an S corporation needs $200,000 for equipment and working capital. In the first route, a bank lends $200,000 to the company and the owner guarantees repayment. The bank sends the cash to the company. In the second route, the owner borrows personally and transfers $200,000 to the company under a separate reviewed arrangement. The balance sheet and owner records must describe the route actually used, including the owner’s separate personal borrowing where relevant.
The fact that both routes produce $200,000 in the corporate account does not make their tax consequences identical. Ask the advisor to identify the borrower, creditor, basis analysis, interest treatment, repayment obligations, and documentation risks for each alternative. Do not change the labels after the transaction solely because one structure would have produced a more attractive loss deduction.
Suppose the owner later pays $25,000 directly to the bank after the company experiences a cash shortage. Record the date, source account, loan balance, and reason. The preparer needs to evaluate the payment and any resulting relationship between the owner and company. A personal bank debit is evidence of a payment; it does not by itself explain all tax consequences or establish how later company repayments should be treated.
Maintain separate lender and shareholder ledgers
The company’s bank-loan ledger should reconcile to lender statements. A shareholder-loan ledger should identify advances, principal repayments, interest, and balances owed to the shareholder. Do not combine the two simply because the owner guaranteed the bank debt. If the company reimburses the owner for a lender payment, document which obligation the reimbursement settles and obtain the appropriate accounting and tax instructions.
For a proposed direct shareholder advance, obtain advice on the agreement, repayment terms, interest, approvals, and funding evidence. The commercial explanation should be understandable: what the company needs, how repayment is expected, and what happens if the forecast fails. A note prepared years later without a reliable transaction history can leave the preparer unable to explain the arrangement.
Bring the financing file to the loss and distribution review
Before relying on corporate losses, provide the preparer current stock and debt basis workpapers and the financing history. Ask which additional limitations may apply. Before repaying a shareholder loan, ask whether prior basis adjustments affect the repayment analysis. A balance on the company books is not a substitute for the shareholder’s tax workpaper.
Record the advisor’s conclusion together with the facts and period covered. Review the file whenever debt is refinanced, guarantees are released, ownership changes, or the owner makes another payment. This guide does not establish debt basis for any specific structure. It gives the owner a way to avoid treating a signature on a guarantee as though cash had necessarily been advanced under a direct shareholder loan, and to preserve the evidence required for an informed professional analysis.
Include a creditor column in the owner financing summary. If one balance belongs to the bank and another to the shareholder, show separate opening balances and payments. Ask the preparer to explain any difference between the company’s debt balance and the shareholder’s tax basis in that debt. Keeping both figures visible avoids the assumption that every dollar recorded as payable to an owner necessarily supports the same dollar of current deduction capacity.
