How do I stop tax money becoming spending money?
Short answer: Move it out of your operating account the moment it accrues. If you can see it, you'll spend it - separation is the only reliable defence.
Almost every business that has been stung by a tax bill has the same story: the money was there, then it wasn't, then BAS day arrived.
The pattern isn't a discipline problem - it's a visibility problem. The fix is structural, not behavioural.
Why willpower doesn't work
When tax money sits in your operating account, your balance constantly tells you that you have more cash than you really do.
Every spending decision - a hire, a piece of equipment, a marketing push - is made against an inflated number. Over a quarter, those small decisions compound into a real shortfall.
Reserve at the point of accrual
The cleanest approach is to move GST out as each invoice is paid, PAYG out as each pay run is processed, and super out as each pay run accrues it.
By the time the obligation is due, the money is already sitting in the tax reserve. You never see it as spendable cash because it never lived in your operating account.
Use a dedicated tax account
A separate account - clearly labelled - removes any ambiguity. Many businesses use one account for GST/PAYG and a second for income tax instalments and super.
The accounts don't need to earn interest or be sophisticated. They just need to be visibly not your operating money.
Pair it with weekly visibility
A short weekly check - operating balance, tax reserve, upcoming obligations - keeps the system honest.
Once the rhythm is established, tax money simply stops feeling like After obligations.
- If tax money is visible in your balance, it will eventually be spent.
- Move GST, PAYG and super out at the moment they accrue, not at BAS time.
- A separate, clearly labelled tax account is the simplest structural fix.
- Weekly visibility keeps the system honest with minimal effort.
