A shareholders' loan is a loan made by a shareholder to their own company. Instead of putting money in as equity, the shareholder lends it, meaning the company owes them a debt. It's one of the most common funding arrangements in small and medium-sized Australian businesses, yet plenty of owners set one up without fully understanding how the Australian Taxation Office views the arrangement, or what happens if it goes wrong.
What a shareholders' loan actually is
When a company needs cash, it has two basic options: bring in equity (issue new shares) or take on debt. A shareholders' loan is a form of debt, but the creditor is the owner rather than a bank. The company records the amount as a liability on its balance sheet, and the shareholder records it as a receivable. If you've ever transferred your own money into a company bank account and expected it back one day, you've likely created a shareholders' loan, even if you never called it that.
The loan can be formal or informal. A formal loan has a written agreement, an interest rate, and a repayment schedule. An informal one is often just an unrecorded transfer. Both are legally real. Only one of them protects you.
How shareholders' loans are used in practice
Small business owners use shareholders' loans for several reasons. Cash flow shortfalls are the most common: the company needs to cover wages or a supplier invoice, and the owner injects funds quickly to bridge the gap. The loan structure lets the owner take that money back later as a repayment, rather than as a dividend (which is taxed differently) or a salary.
Some owners also use shareholders' loans as a deliberate tax-planning tool. Because a repayment of loan principal isn't income, it doesn't attract income tax in the same way a dividend or salary does. This is a genuine advantage, but it's also one the ATO watches closely. Done incorrectly, what looks like a loan repayment can be reclassified as a Division 7A deemed dividend, triggering an unexpected tax bill.
Division 7A: the rule every shareholder needs to know
Division 7A of the Income Tax Assessment Act 1936 is the section of Australian tax law designed to stop private company shareholders from accessing company profits tax-free through loans. The rule is blunt: if a private company makes a payment or loan to a shareholder (or their associate), and it isn't repaid by the time the company lodges its tax return, the ATO treats the amount as an unfranked dividend. That means the shareholder pays income tax on it at their marginal rate, with no franking credit to offset the bill.
There's a way around this. If the loan is documented under a complying loan agreement, with a minimum interest rate (set by the ATO each year, based on the Reserve Bank's indicator lending rate) and a repayment term of either 7 years for unsecured loans or 25 years for loans secured by real property, it won't be deemed a dividend. But the documentation has to exist before the company lodges its tax return for the year the loan was made. Missing that deadline is expensive.
Understanding how Division 7A interacts with broader company finances is closely tied to understanding what a balance sheet actually shows, since the loan appears as both a liability of the company and an asset of the shareholder.
Interest, repayment, and what to document
A complying loan agreement doesn't need to be complex, but it does need to cover four things: the loan amount, the interest rate, the repayment schedule, and whether it's secured. Both parties sign it before the company's tax return is due.
The minimum interest rate for 2026 is set annually by the ATO. Charging less than this rate, or charging no interest at all, can invalidate the agreement. The interest the company pays to the shareholder is also income in the shareholder's hands, so there's a tax cost either way. That's why many owners who use shareholders' loans prefer to set the interest at the exact ATO benchmark rate and no higher.
Repayments must be made on schedule. If a year is missed, that missed repayment can itself be treated as a deemed dividend. The ATO is specific about this. It's not enough to catch up in the following year.
When a shareholders' loan is the right tool
A shareholders' loan works best in three situations. First, when the company has a short-term cash need and the owner expects to be repaid within the financial year, avoiding Division 7A entirely. Second, when the owner wants to retain flexibility over how they extract value from the company and doesn't want to lock in a salary or declare a dividend right now. Third, as part of a structured arrangement where the loan is documented properly and forms part of a deliberate funding strategy alongside equity.
It's not the right tool when the owner has no clear expectation of repayment. A loan that's never repaid isn't really a loan. It's an equity contribution that's been mislabelled, and the ATO will eventually treat it that way. This is where the distinction between a shareholders' loan and a convertible note matters: a convertible note is designed from the start to convert into equity, while a shareholders' loan is meant to remain debt unless both parties agree otherwise.
What happens if the company can't repay
If the company becomes insolvent and can't repay the shareholders' loan, the shareholder is treated as an unsecured creditor (unless the loan was secured over an asset). In a liquidation, unsecured creditors are typically paid last, often after the ATO, employees, and secured lenders. In practice, this means shareholders who lent money to their own company often recover nothing.
This is a real risk that many business owners underestimate. When the company is thriving, the loan looks like a flexible, tax-efficient instrument. When it fails, it looks like capital that was never protected. Getting the structure and documentation right from the beginning isn't just about tax compliance. It's about protecting your own position if things go badly.
A qualified accountant familiar with private company tax rules is worth consulting before setting up any shareholders' loan arrangement. The ATO publishes detailed guidance, but the specifics of Division 7A have tripped up experienced operators as well as first-time business owners.
