A genuine loan needs a real obligation to repay, credible terms, payment history, and consistent accounting; otherwise advances may be treated as equity or distributions.

The tax treatment

A genuine loan needs a real obligation to repay, credible terms, payment history, and consistent accounting; otherwise advances may be treated as equity or distributions. This is a federal income tax starting point; the contract, ownership, accounting method, and actual use can change the result. State and local treatment should be checked separately.

The decision to make before filing

Set interest, maturity, and repayment terms when funds move rather than after an audit begins. The useful planning step is to resolve the classification while the underlying documents are still available, then reconcile it to the books and the prior-year return. If the transaction spans more than one year, track the opening balance and what happened to it afterward.

Illustrative example

A shareholder advances cash to a company during a slow quarter. A contemporaneous note states repayment terms and interest, and actual payments follow the agreement. Without those facts, a later claim that the transfer was debt is much harder to defend.

Records that support the position

Keep signed note, bank transfers, payment ledger, and corporate approvals. Tie amounts on the return to bank activity and the agreement. When several assets, people, or uses are involved, write down the allocation method and apply it consistently. A short dated workpaper is easier to defend than a reconstructed explanation years later.

A common reporting error

A year-end journal entry called loan cannot substitute for an actual debtor-creditor relationship. Review both sides of the entry: a payment can affect income, basis, liability, or an expense at different times. A correct cash total alone does not establish the correct tax character.

Where to verify the rule

Start with IRS Publication 334: Tax Guide for Small Business. Its examples and cross-references explain the underlying federal rule; check the current version and any later IRS guidance for the year at issue.
