Proven tips to use offset accounts when self employed

Offset accounts save interest without locking away working capital

An offset account sits alongside your loan and reduces the balance you're charged interest on, dollar for dollar. If you've got $300,000 owing and $40,000 in the offset, you pay interest on $260,000. The difference between an offset and parking money in a savings account or redraw facility is timing and tax. You can pull funds out of an offset whenever you need them without asking the bank, and because you're not earning interest on the balance, there's no additional assessable income to declare.

For anyone running a business, that second point matters. When you're self employed, every dollar of declared income affects your marginal tax rate and your borrowing capacity on the next deal. Interest earned in a standard savings account gets added to your assessable income and taxed accordingly. An offset delivers the same outcome by reducing interest paid rather than creating interest earned, so the ATO doesn't see it and your profit and loss stays clean.

Linked offsets work better than partial offsets for variable cashflow

A linked offset is tied directly to your loan account and offsets 100% of the balance held in it. Some lenders offer partial offsets that only reduce interest on a portion of the funds, usually around 60% to 80%, which makes no sense for a business owner juggling invoices and supplier payments. If you're moving $50,000 in and out of the account to manage cashflow, you want full value for every dollar that sits there, even if it's only for a week.

In our experience, partial offsets show up most often in package deals where the bank bundles a low headline rate with restrictions buried in the features. When you're comparing loan options, confirm whether the offset is 100% linked and whether you can have multiple offset accounts under the one loan. Some lenders allow up to five or six linked accounts, which lets you separate operating funds from tax provisions or quarterly BAS payments without losing the interest benefit.

You can't offset an investment loan and call it a business expense

If your loan is for an investment property, the ATO expects you to maximise the deductible debt on that asset, not reduce it. Parking business income in an offset linked to an investment loan lowers the interest you're charged, which lowers the deduction you can claim. That might sound like a technical point, but it changes the math completely when you're weighing up whether to pay down debt or hold liquidity.

Consider a scenario where you've got an investment property with $400,000 owing at a variable rate and $80,000 in business revenue sitting in the offset. You're paying interest on $320,000 instead of $400,000, which saves you roughly $4,000 a year in interest depending on the rate. But you've also reduced your deductible interest by the same amount, so the tax benefit of holding that debt has dropped. If you're on a marginal rate of 39%, that $4,000 in lost deductions costs you around $1,560 in additional tax. The net saving is still positive, but it's not $4,000. If the same funds were sitting in an offset linked to your owner occupied home loan, you'd get the full value of the interest reduction without any tax consequences.

Fixed loans don't allow offsets in most cases

Most lenders won't let you attach an offset to a fixed rate loan because the interest calculation is locked in at the time you fix. A handful of lenders do offer offsets on fixed loans, but the rate tends to be higher than a standard fixed product, and the offset benefit is capped or tiered. If you're fixing part of your loan to lock in repayments while keeping the rest on a variable rate, the offset should sit with the variable portion.

That split rate structure works well when you've got uneven income through the year. The fixed portion gives you certainty on minimum repayments, and the variable portion with the offset lets you park surplus cashflow when revenue is strong and pull it back out when things are tight. You're not paying a redraw fee every time you need access, and you're not waiting for the bank to approve a withdrawal. The funds move in and out as you control them.

Offsets don't suit every business owner

If your operating account rarely holds more than a few thousand dollars because you're reinvesting everything into stock, equipment, or paying yourself a wage through a company structure, an offset won't deliver much value. The interest saving is proportional to the balance you hold, so if the account sits empty most of the time, you're paying for a feature you're not using. Some lenders charge an annual package fee of $300 to $400 to access an offset account, and that fee doesn't disappear just because you're not holding funds in it.

In that situation, a no-frills variable loan with a lower rate and no package fee will cost you considerably less over the year. You can always refinance into a product with an offset later if your cashflow changes or you start building a buffer. The decision comes down to whether you're holding surplus funds regularly enough to cover the cost of the feature, and whether you value the flexibility of instant access over a lower headline rate.
