A loan from a corporation to a shareholder is tax-free only when it holds up as genuine debt under IRS shareholder loan rules: a written note, a market interest rate tied to the Applicable Federal Rate, a fixed repayment schedule, and actual payments made and enforced. Fall short and the IRS can reclassify the whole balance as a dividend, a distribution, or wages. That reclassification brings back taxes, a 20% accuracy-related penalty, interest running from the original return’s due date, and in some cases payroll taxes on top.
What Makes a Shareholder Loan Real Debt
Courts built a multi-factor test over decades of litigation to sort real shareholder debt from disguised distributions. An IRS practice unit collects the core factors: whether a written instrument exists, whether it states an interest rate and maturity date, whether the debt is enforceable under state law, whether repayment expectations are reasonable, whether the lender has remedies on default, and whether the parties actually followed the agreement’s terms.1Internal Revenue Service. Valid Shareholder Debt Owed by S Corporation No single factor decides the question, but failing several at once usually ends the argument.
Start with a promissory note. It should state the principal, the interest rate, a fixed repayment schedule with specific due dates, and a maturity date. Terms like “payable on demand” or “when the shareholder is able” invite reclassification because they signal the corporation never expected to collect. The schedule also has to be realistic given the shareholder’s finances. A $500,000 note with $200-a-month payments and no balloon looks like a loan nobody meant to repay.
The shareholder has to actually make the payments, and the corporation has to actually enforce the note. Missed payments that go unchallenged are one of the strongest signals the transaction was a distribution in disguise. If the shareholder falls behind, the corporation should send formal demand letters or charge late fees, just as an unrelated lender would.
Collateral is not strictly required, but securing the loan with shareholder assets strengthens the case. A security interest gives the corporation a real remedy on default and shows both sides treated the arrangement as a genuine financial obligation.
The loan must be formally authorized in the corporation’s minutes or a board resolution. It is easy to skip and just as easy for an auditor to check. Without it, the transaction reads as an informal withdrawal rather than a deliberate corporate decision to extend credit.
The Interest Rate Rule and the $10,000 Exception
For any loan above $10,000, Section 7872 requires the stated rate to be at least the Applicable Federal Rate the IRS publishes monthly.2Office of the Law Revision Counsel. 26 USC 7872 – Treatment of Loans With Below-Market Interest Rates Charge less and the IRS imputes the missing interest, creating taxable income nobody actually received in cash. The AFR comes in three tiers by loan term: short-term (three years or less), mid-term (over three but not more than nine years), and long-term (over nine years).3Internal Revenue Service. Applicable Federal Rates Compounding at least semiannually satisfies the statute. Setting the rate at or above the AFR for the correct term is the single easiest step in the process, and skipping it is the single most common mistake.
Small loans get a pass. If the total outstanding balance between the corporation and the shareholder stays at or below $10,000 on any given day, the below-market interest rules do not apply for that day.2Office of the Law Revision Counsel. 26 USC 7872 – Treatment of Loans With Below-Market Interest Rates The exception vanishes the moment aggregate loans cross $10,000, even temporarily, and it disappears entirely if one of the principal purposes of the arrangement is federal tax avoidance.
Demand Loans Versus Term Loans
The AFR mechanics differ depending on the loan’s structure. A demand loan is one payable whenever the lender asks for it. Loans with no fixed maturity are treated the same way. Everything else is a term loan.2Office of the Law Revision Counsel. 26 USC 7872 – Treatment of Loans With Below-Market Interest Rates
For a demand loan, the applicable rate is the short-term AFR and it floats. If short-term rates rise, so does the forgone interest calculation, and the IRS treats forgone interest as recognized on December 31 each year the loan is outstanding. For a term loan, the AFR is locked in on the day the loan is made using the rate that matches the loan’s duration, and the below-market discount is treated as transferred upfront. A below-market term loan accelerates the tax hit; a below-market demand loan spreads it out annually.
The Phantom Income Problem
When a loan charges less than the AFR, the gap is called forgone interest. The IRS treats it as if two things happened at once: the corporation paid that amount to the shareholder as a dividend or compensation, and the shareholder paid it right back as interest.2Office of the Law Revision Counsel. 26 USC 7872 – Treatment of Loans With Below-Market Interest Rates
Both sides pick up phantom income. The corporation reports interest income it never actually collected. The shareholder reports a distribution or dividend equal to the forgone interest. The shareholder can theoretically deduct the imputed interest payment, but only if the loan proceeds were used for investment or business purposes. Loan proceeds spent on personal expenses generate taxable imputed income with no offsetting deduction.
What Happens If the IRS Reclassifies the Loan
Reclassification means the IRS has concluded the advance was never a loan at all. The full principal is recharacterized as a transfer of value on the date it was made. The consequences depend on the corporate structure and on what the IRS decides the transfer actually was.
C Corporation: Constructive Dividend
In a C corporation, the reclassified amount becomes a constructive dividend. Under Section 316, a dividend is any distribution from a corporation’s accumulated or current-year earnings and profits.4Office of the Law Revision Counsel. 26 USC 316 – Dividend Defined If the corporation has sufficient E&P, the entire amount is taxable to the shareholder at qualified dividend rates.5Internal Revenue Service. Topic No. 404 Dividends and Other Corporate Distributions
The sting is double taxation. The corporation already paid corporate tax on those earnings. The shareholder pays a second layer on the same money. Constructive dividends are not deductible by the corporation, so there is no offsetting corporate tax benefit. If the reclassified amount exceeds E&P, the excess is first a tax-free return of stock basis, then capital gain.
S Corporation: Distribution or Disguised Wages
For an S corporation, the outcome splits two ways. If the IRS treats the advance as a distribution, it follows the Section 1368 ordering rules. Without accumulated E&P from a prior C corporation period, the distribution reduces the shareholder’s stock basis dollar for dollar and is tax-free to that extent, with any excess taxed as capital gain.6Office of the Law Revision Counsel. 26 USC 1368 – Distributions A reclassified distribution also reduces stock basis under Section 1367, which can suspend pass-through losses on the shareholder’s Schedule K-1 until basis is restored.7Office of the Law Revision Counsel. 26 USC 1367 – Adjustments to Basis of Stock of Shareholders, Etc.
The worse outcome is reclassification as disguised compensation. This is especially likely when the shareholder works in the business, takes a below-market salary or no salary at all, and regularly pulls cash out as “loans.” The IRS has said plainly that S corporations should not use loans or distributions to avoid paying employment taxes on officer compensation.8Internal Revenue Service. Wage Compensation for S Corporation Officers If the advance is deemed wages, the entire amount is subject to ordinary income tax, the employer’s share of Social Security and Medicare taxes, and federal unemployment tax, and the corporation must also account for the employee’s share of payroll taxes it failed to withhold.9Internal Revenue Service.

Forgiving the Loan Does Not Erase the Tax
Writing off a shareholder’s balance does not make it disappear. When a corporation cancels a shareholder debt, the IRS generally treats the forgiven amount as a constructive dividend (C corporation) or a distribution (S corporation), not as ordinary cancellation-of-debt income. The shareholder-corporation relationship makes the write-off a transfer of value from the company to the owner, and it follows the same tax path as reclassification.
In a C corporation, the forgiven amount is a dividend to the extent of E&P, carrying the double-taxation problem. In an S corporation, the forgiven balance runs through the Section 1368 ordering, potentially consuming basis and creating capital gain. If the shareholder was also providing services, the IRS may instead treat part or all of the forgiven amount as compensation and trigger payroll taxes.
Penalties and Interest
The back tax is only the starting point. The IRS typically assesses a 20% accuracy-related penalty on the underpayment when it reclassifies a shareholder loan. The penalty applies to underpayments caused by negligence, disregard of rules, or a substantial understatement of income tax. For individuals, a substantial understatement means the underpayment exceeds the greater of 10% of the correct tax or $5,000.10Office of the Law Revision Counsel. 26 USC 6662 – Imposition of Accuracy-Related Penalty on Underpayments
Interest runs from the original due date of the return, not from the date the IRS raises the issue. For a loan made several years back, that interest compounds quickly. If the recharacterization is to compensation, the corporation also faces penalties for failing to withhold employment taxes and failing to file the required payroll returns. A single reclassified loan can cascade into penalties touching corporate and individual returns across multiple tax years.
Reporting the Loan Correctly
The loan belongs on the corporation’s balance sheet as a receivable, classified current or long-term based on the repayment schedule. Both parties should keep a payment ledger showing each payment date, the split between principal and interest, and the remaining balance. The ledger, promissory note, board resolution, and bank records of actual payments form the documentary backbone of the loan’s bona fide status.
Interest the corporation collects is ordinary income. A C corporation reports it on Form 1120, line 5.11Internal Revenue Service. Form 1120 – U.S. Corporation Income Tax Return An S corporation reports it on Form 1120-S and passes it through to shareholders as interest income on Schedule K-1.12Internal Revenue Service. Schedule K-1 (Form 1120-S) – Shareholder’s Share of Income, Deductions, Credits, Etc.
The shareholder who pays interest to the corporation may be able to deduct it on their personal return, but only based on how the loan proceeds were used. Investment-use interest may qualify as investment interest expense, subject to the net investment income limit. Personal-use interest is not deductible. Business-use interest may qualify as a business expense. Keeping records that trace the proceeds to their actual use is critical for supporting any deduction.
If the IRS reclassifies the loan as a C corporation dividend, the corporation must issue a Form 1099-DIV to the shareholder for the reclassified amount. The minimum filing threshold for dividends is $10.13Internal Revenue Service. Instructions for Form 1099-DIV If the reclassification is to S corporation compensation, the corporation must issue a corrected or original Form W-2 reflecting the amount as wages subject to income and employment tax withholding.8Internal Revenue Service.
