A loan from a shareholder on the balance sheet is recorded with a debit to Cash for the funds received and a credit to a liability account typically labeled “Shareholder Loan Payable” or “Loans from Shareholders.” That liability sits as a current liability if the principal is due within 12 months, or splits between current and long-term if repayment runs past a year. The entry itself is straightforward. The work that matters is structuring and documenting the loan so the IRS treats the balance as genuine debt rather than a disguised equity contribution.
Recording the Loan and Classifying the Liability
On the day the company receives the money, debit Cash for the principal and credit Shareholder Loan Payable for the same amount. The liability stays on the books until the principal is repaid.
Classification on the balance sheet follows the repayment timeline. Principal due within 12 months of the reporting date is a current liability. Principal that extends beyond 12 months belongs under non-current liabilities. A multi-year note gets split each period: the next 12 months of scheduled principal as current, the remainder as long-term. Update the split every reporting period as payments come due.
Accruing Interest and the Related-Party Payment Deadline
Interest on the outstanding balance has to be recorded every period, whether or not the shareholder has actually been paid. The periodic entry is a debit to Interest Expense and a credit to Interest Payable. Skipping it understates liabilities and overstates income on the financials, and creates a separate problem with the IRS.
Shareholder loans carry a timing rule that arm’s-length loans don’t. When a company owes interest to a shareholder who owns more than 50% of its stock, and that shareholder reports income on a cash basis, the company can only deduct the interest in the year it actually pays. If the interest is accrued on the books but not paid within two and a half months after the company’s tax year ends, the deduction for that year is permanently lost.1eCFR. 26 CFR 1.267(a)-1 – Deductions Disallowed The 50% test uses constructive ownership rules, so shares held by family members and certain related entities count toward the threshold.2Office of the Law Revision Counsel. 26 U.S. Code 267 – Losses, Expenses, and Interest With Respect to Transactions Between Related Taxpayers
If you’re a majority shareholder lending to your own company, the company needs to cut you an actual interest check before that window closes. Book entries alone will not preserve the deduction.
Keeping the Balance Classified as Debt and Not Equity
The IRS can reclassify a shareholder loan as an equity contribution when the transaction looks more like an investment than a real obligation to repay. This is the single biggest risk around any shareholder loan sitting on the balance sheet. The tax code authorizes Treasury to prescribe factors for distinguishing debt from equity, and those factors mirror what courts have applied for decades.3Office of the Law Revision Counsel. 26 U.S. Code 385 – Treatment of Certain Interests in Corporations as Stock or Indebtedness
No single factor controls the outcome, but these are the ones that drive it:
- A signed promissory note stating the principal, interest rate, payment schedule, and a fixed maturity date, executed before or on the date of the cash transfer.
- A specific maturity date. Open-ended advances with no due date look like capital.
- An interest rate that reflects what an unrelated lender would charge. Zero or token interest is a red flag.
- A realistic ability to repay from projected cash flow at the time the loan was made.
- Shareholder claims that are not automatically subordinated to all outside creditors.
- A debt-to-equity ratio that doesn’t leave the company thinly capitalized.
- Loan amounts that are not perfectly proportional to each shareholder’s ownership percentage.
- Enforcement when payments are missed. A real creditor sends a default notice or documents a forbearance, rather than quietly letting payments slide.
The proportionality factor catches people off guard. When two 50/50 shareholders each lend the company $100,000, the mirrored amounts suggest the advances are really additional capital. Staggered amounts, different rates, or different timing all help break that pattern.
Board approval belongs in the paper trail. The directors (or members/managers of an LLC) should formally authorize the borrowing in a resolution or minutes that record the business purpose and the terms. If the loan is secured by company assets, execute a security agreement and file a UCC-1 with the appropriate secretary of state. Perfecting the security interest isn’t required for debt treatment, but it’s strong evidence that the shareholder behaved like a real creditor.
Below-Market Interest and the AFR
Charging too little interest creates a separate tax problem on top of the debt-classification risk. Federal law treats the gap between the rate you charge and the minimum rate as a taxable transfer between the parties.4Office of the Law Revision Counsel. 26 USC 7872 – Treatment of Loans With Below-Market Interest Rates
The minimum is the Applicable Federal Rate, which the IRS publishes monthly. Three tiers apply based on the loan’s term: short-term (up to three years), mid-term (over three years but not more than nine), and long-term (over nine years).5Internal Revenue Service. Applicable Federal Rates (AFRs) Rulings You lock in the AFR in effect when the loan is made.
If your stated rate falls below the AFR, the IRS treats the forgone interest as though the corporation paid it to the shareholder and the shareholder paid it back. For a corporation-to-shareholder loan, that forgone amount is recharacterized as a distribution from the corporation, then as interest income received by the shareholder. Both sides owe tax on amounts that never actually moved.
A narrow exception: if the total outstanding loan balance between the shareholder and the corporation stays at $10,000 or below, the imputed interest rules don’t apply.4Office of the Law Revision Counsel. 26 USC 7872 – Treatment of Loans With Below-Market Interest Rates That threshold covers small short-term advances but little else.
Tax Treatment When the Loan Holds Up
When the balance qualifies as real debt, the treatment is clean. The company deducts the interest it pays as an ordinary business expense.6Internal Revenue Service. Questions and Answers About the Limitation on the Deduction for Business Interest Expense The shareholder reports the interest as taxable interest income. If the company pays more than $10 of interest during the year, it issues a Form 1099-INT to the shareholder.7Internal Revenue Service. About Form 1099-INT, Interest Income Repayment of principal is not a taxable event for either side; it’s a return of capital.
One caveat beyond the related-party payment deadline above: a general cap on business interest deductions applies to larger companies, limiting the deduction to 30% of adjusted taxable income with carryforward of the excess. Businesses that meet a gross receipts test (averaging $31 million or less over the prior three years, as of 2025) are exempt.6Internal Revenue Service. Questions and Answers About the Limitation on the Deduction for Business Interest Expense Most closely held companies with shareholder loans fall under the exemption.
What Reclassification Costs
If the IRS recharacterizes the shareholder loan as a capital contribution, the company loses every interest deduction it previously claimed on the reclassified amount. The shareholder’s stock basis increases by the reclassified principal, which may help on a future sale but does nothing in the current year.
The bigger hit lands when the company “repays” the loan. Because the balance is now equity, the payment is a corporate distribution. To the extent the company has current or accumulated earnings and profits, that distribution is taxed to the shareholder as a dividend, and the corporation gets no deduction for it. Amounts above earnings and profits reduce the shareholder’s stock basis, and anything above basis is capital gain. The arrangement ends up producing lost deductions for the company and a tax bill for the shareholder on money they originally lent in.
S-Corporation Shareholders: Debt Basis
For S-corp shareholders, the loan balance on the books is doing a second job beyond tracking a liability. An S-corp shareholder can only deduct passed-through losses up to two pools: stock basis plus basis in loans the shareholder has personally made to the corporation.8Internal Revenue Service. S Corporation Stock and Debt Basis Losses beyond both pools suspend and carry forward. That makes shareholder lending one of the main tools S-corp owners use to free up loss deductions in bad years.
Losses reduce stock basis first; only after stock basis is zero do they start eating into debt basis. When the company turns profitable, the restoration order flips: income rebuilds debt basis first, then stock basis.9Office of the Law Revision Counsel. 26 U.S. Code 1367 – Adjustments to Basis of Stock of Shareholders, Etc.
If the company repays a loan whose basis has been reduced by losses, the shareholder has a taxable gain equal to the difference between what they receive and the loan’s remaining basis. A properly documented loan with a promissory note produces capital gain. An informal open-account advance produces ordinary income, which is taxed at higher rates. That alone is often reason enough to put the note in writing before the money moves.
If an S-corp shareholder loan fails the debt-versus-equity test, the advance is treated as a stock contribution instead. Stock basis goes up by the same amount, but the separate debt basis pool is lost entirely.8Internal Revenue Service. S Corporation Stock and Debt Basis In a big loss year that difference can mean tens of thousands of dollars of deductions the shareholder cannot use.
A note on back-to-back arrangements: a shareholder who borrows from a bank and re-lends to the S-corp only gets debt basis if the transaction creates a genuine debtor-creditor relationship between the shareholder and the corporation. The S-corp’s books must show a payable to the shareholder, not to the bank, and the loan documents must identify the shareholder as the creditor. A mere guarantee of the bank loan does not create debt basis.10Internal Revenue Service. Valid Shareholder Debt Owed by S Corporation
Reporting the Balance on the Tax Return
The shareholder loan balance flows from the books to specific lines on the federal return. For an S-corporation filing Form 1120-S, the balance goes on Schedule L (Balance Sheets per Books), Line 19, labeled “Loans from shareholders.” Each shareholder’s Schedule K-1 also reports the debt the S-corp owes directly to that shareholder as of the beginning and end of the year.11Internal Revenue Service. Instructions for Form 1120-S
For a C-corporation filing Form 1120, shareholder loans appear as liabilities on Schedule L. If the corporation has 25% or more foreign ownership with related-party transactions, additional disclosure on Form 5472 may be required.
Consistency across the balance sheet, the K-1s, and the underlying loan documents is critical. The IRS cross-references Schedule L against the K-1 figures and the loan agreement, and mismatches are among the first things auditors flag.
When the Shareholder Forgives the Loan
Sometimes the shareholder cancels the outstanding balance instead of waiting to be repaid. The tax result depends on how the cancellation is structured.
When a shareholder cancels the debt as a contribution to the company’s capital, the corporation is treated as having satisfied the debt with an amount equal to the shareholder’s adjusted basis in the loan, typically the outstanding principal. If the shareholder’s basis equals the face value, no cancellation-of-debt income results for the corporation.12Office of the Law Revision Counsel. 26 U.S. Code 108 – Income From Discharge of Indebtedness The shareholder’s stock basis increases by the amount forgiven, since the cancellation is treated as a capital contribution.
If the cancellation is structured as a simple write-off instead, the corporation may recognize cancellation-of-debt income equal to the face value of the loan. An insolvent corporation can exclude that income up to the amount of insolvency; a solvent corporation owes tax on the full amount. For S-corporations, these exclusions apply at the corporate level rather than passing through to shareholders.12Office of the Law Revision Counsel. 26 U.S. Code 108 – Income From Discharge of Indebtedness
Pick the structure, and paper it, before executing the forgiveness. The difference between a capital contribution and a simple cancellation can mean a sizable unexpected tax bill for the corporation.
