The Hidden Tax Risks of Using Personal Offset Accounts for Business Funds

It might seem like a clever strategy - moving surplus business cash into your personal mortgage offset account to save on home loan interest, then shifting it back to the company around tax time. But there’s a catch: the ATO sees this, and they’re not fans.

This approach, while common among company-operating business owners, can trigger serious tax implications under Division 7A of the Tax Act. And specifically, Section 109R exists to prevent exactly this kind of timing play.

What the Law Actually Says:

If you (or an associate) owe money to your company, and you “repay” it before 30 June - only to borrow a similar or larger amount shortly after - then you haven’t really repaid the loan in the eyes of the ATO.

In fact, there are two key red flags that will likely lead to that repayment being disregarded:

  1. The Intent Test
    A reasonable person would conclude that you intended to borrow again - either the same or more - when making the repayment.
  2. The Roundabout Loan Test
    You received a new loan from the company to repay the first one, effectively swapping one loan for another to skirt Division 7A rules.

If either applies, the repayment is disqualified and the funds can be treated as an unfranked dividend - which means you could be left with a larger tax bill than expected.

Why It Matters

Tax strategies should build long-term confidence, not short-term loopholes. Paying tax on profits withdrawn from your company might seem less attractive upfront, but done correctly, it’s part of a sustainable and smart financial strategy.
