C-Corporation Loans to Shareholders: Tax Rules and Risks

A C corporation can make a bona fide loan to a shareholder. The loan is not automatically a dividend, and the corporation may earn taxable interest. But a payment labeled loan can be reclassified as a constructive dividend when the facts do not show a real debtor-creditor relationship.

The analysis focuses on intent and behavior at the time funds move. A promissory note created only after an audit begins does not repair years of missing payments and personal withdrawals.

What Makes the Debt Bona Fide

Use a written promissory note that states principal, a fixed maturity date, payment schedule, interest rate, default provisions, and security when appropriate. Approve the loan through the corporation's normal governance process and record it consistently in the general ledger and financial statements.

The shareholder should have the ability to repay from sources other than future corporate distributions. Actual payments according to schedule, enforcement after default, and treatment comparable to an unrelated borrower support debt characterization.

Interest and Below-Market Loan Rules

A shareholder loan should generally charge at least the applicable federal rate for the term and payment structure. Section 7872 can impute interest on below-market loans and treat the foregone amount through a deemed transfer and retransferred interest payment.

Interest received is taxable income to the corporation. The shareholder's interest deduction, if any, depends on how the borrowed funds are used and the applicable personal, investment, or business-interest rules.

Constructive Dividend Risk

A constructive dividend can arise when a corporation confers an economic benefit on a shareholder without an expectation of repayment. Factors include no note, no maturity, no security, no payments, repeated advances, weak repayment capacity, withdrawals proportional to ownership, and the corporation's failure to enforce the obligation.

A dividend is generally taxable to the shareholder to the extent of corporate earnings and profits and is not deductible by the corporation. Reclassification can also produce interest and penalty exposure.

A Loan Does Not Eliminate Accumulated Earnings Tax

Keeping profits inside a C corporation for reasonable business needs can be appropriate. Accumulating earnings beyond those needs to avoid shareholder tax can create accumulated-earnings-tax exposure. Lending the cash to the shareholder for personal investment does not necessarily establish a corporate business need and may strengthen the inference that earnings were retained for shareholders.

Document working capital, acquisitions, equipment, debt service, litigation reserves, expansion, and other specific corporate needs separately from any shareholder loan.

Annual Administration

Reconcile principal and accrued interest, issue any required tax reporting, make payments through traceable accounts, document modifications before default, test collectibility, and report related-party balances consistently on the corporate return. Large or recurring loans deserve formal annual review by the tax and legal teams.

Worked Example: Investment Loan to the Owner

Assume a profitable C corporation advances $500,000 to its sole shareholder for a brokerage investment. The board approves a five-year secured note, the rate is set at a supportable market rate above the applicable federal rate, and monthly principal and interest payments begin immediately from the shareholder's outside income. The corporation reports interest income and enforces the note. Those facts support a genuine loan, although they do not guarantee the result.

Now assume the same funds are posted to due from shareholder at year-end, with no note, no maturity, no payments, no collateral, and no realistic repayment source other than future corporate distributions. The shareholder takes similar advances each year. Those facts point toward a constructive dividend or other distribution rather than debt.

The company should also consider corporate-law restrictions, lender covenants, solvency, fiduciary duties to minority owners, and whether the transfer interferes with documented business needs. Tax compliance is only one part of the approval decision.

Frequently Asked Questions

Can my C corporation lend me money to invest?

Potentially, if the loan is bona fide, properly documented, adequately capitalized, and actually repaid. The use of proceeds also affects the shareholder's interest deduction.

What interest rate should the note use?

The applicable federal rate is an important minimum benchmark, but a supportable market rate may be higher based on term, credit risk, security, and payment structure.

Can I repay the loan with future dividends?

A payment can reduce the balance, but relying only on future distributions may weaken evidence of independent repayment capacity. The full facts determine whether debt is genuine.
