Defending shareholder debt: The Ninth Circuit's 11-factor test

When closely-held clients put cash into their own corporation, they rarely think about how the IRS will characterize the advance years later. But if the advance looks more like equity than debt, the consequences are sharp: interest deductions may be disallowed, "loan repayments" may be treated as taxable dividends or other shareholder distributions and worthless debt write-offs may be denied. For clients in the Ninth Circuit, the framework an examiner will reach for is the 11-factor test from A.R. Lantz Co. v. United States, 424 F.2d 1330 (9th Cir. 1970), refined in Bauer v. Commissioner, 748 F.2d 1365 (9th Cir. 1984), and Hardman v. United States, 827 F.2d 1409 (9th Cir. 1987).

What the test does

The test sorts shareholder advances into one of two buckets: a true debtor-creditor obligation, where repayment is expected regardless of corporate fortunes, or capital placed at the risk of the business. No single factor controls. The Ninth Circuit has been explicit that overweighting one factor can invite reversal; the inquiry is factual and turns on substance over form.

The 11 factors

Courts in the Ninth Circuit weigh:

1. The names given to the certificates or instruments evidencing the indebtedness
2. The presence or absence of a maturity date
3. The source of the payments
4. The right to enforce payment of principal and interest
5. Participation in management
6. Status equal to or inferior to regular corporate creditors
7. The intent of the parties
8. Thin or adequate capitalization
9. Identity of interest between creditor and stockholder
10. Whether "interest" is paid only out of "dividend" money
11. The corporation's ability to obtain loans from outside lending institutions

Each factor is read against the rest. A signed promissory note with a fixed maturity (factors one and two) won't save an advance if the corporation is thinly capitalized, pays "interest" only when surplus exists and could never have borrowed the same amount from a bank.

Where deductions actually fall apart

Three patterns often drive reclassification risk:

• Pro rata advances. When shareholders fund the corporation in proportion to stock ownership, factor nine lights up immediately. Vary the ratio when it's feasible, or document why proportionality is incidental rather than designed.
• No paper trail or enforcement. Missed payments that go uncollected, no demand letters, no security interest; the Tax Court reads these as evidence the "creditor" never expected repayment in the ordinary commercial sense.
• Thin capitalization. If a third-party lender wouldn't have made the same loan, factor 11 tips hard toward equity. An independent rating, evidence of comparable third-party lending terms or a contemporaneous capitalization analysis in the file can make a difference.

Applying the rules

For closely-held clients planning a capital infusion, build the debt record before the advance, not after the audit notice. That means a written promissory note with a fixed maturity, market-rate interest, a real repayment schedule, books that record a payable from the corporation to the shareholder (not the other way around) and evidence the corporation could have borrowed elsewhere on similar terms.

The IRS's own LB&I Practice Unit on shareholder debt instructs examiners to apply the test of the circuit controlling the taxpayer and identifies A.R. Lantz Co. as Ninth Circuit authority for the 11-factor framework. In the Ninth Circuit, that test traces to Lantz. When the factors get weighed, the ones that move first are the ones with documentation behind them. Treat the eleven-factor framework as the audit checklist it has become, and your client's interest deductions are better positioned to survive.
