December bank accounts fill with a particular kind of money: gift cards sold, deposits on January jobs, retainers and prepaid service plans. It arrives like revenue, sits in the account like revenue, and often gets spent like revenue. The problem is that it is not revenue yet. It is unearned income, money you hold against an obligation you have not met, and it deserves different treatment in your books, your tax thinking and your cash planning.
What makes this money different?
Accounting recognises revenue when you deliver, not when you are paid. A gift card sold before Christmas is not a sale; it is cash in your account paired with a matching obligation to hand over goods or services whenever the holder redeems it. The sale happens at redemption. The same logic covers the deposit on a job you have not started, the retainer for work not yet done, and the annual plan paid up front. In each case you have the customer's money and they have your promise, and honest books show both sides.
How does the bookkeeping actually work?
Instead of crediting a sales account when the money arrives, you credit a liability account: gift cards outstanding, customer deposits, or income in advance. When you deliver the goods, perform the work, or see the card redeemed, you transfer the relevant amount from the liability account into revenue. That is the whole mechanism. A competent bookkeeper can set up the accounts and the routine quickly, and if you sell gift cards through a point-of-sale system, the integration with your accounting file can usually handle the treatment automatically once it is configured correctly. The one-off setup is the entire cost of getting this right forever.
What about GST and income tax?
Tax broadly follows the same earning-versus-receiving logic, but the details are specific and they move. GST on vouchers and gift cards has its own attribution rules that differ from ordinary sales, and the treatment of deposits can depend on whether and when they become forfeitable or are applied to a supply. Income tax for a business on an accruals basis generally turns on when income is earned rather than when cash lands. Rather than working from remembered rules, have your accountant confirm how each category applies to you, and treat the ATO's published guidance as the source of truth for the current mechanics.
What does consumer law expect?
Unearned money also carries obligations that have nothing to do with bookkeeping. The Australian Consumer Law sets minimum validity requirements for most gift cards and restricts certain fees on them, and there are rules and state-based expectations around when deposits can be kept and when they must be returned. If you take deposits, your terms should say plainly what happens if the customer cancels, what happens if you cancel, and when the deposit stops being refundable. The ACCC and your state's fair trading body publish the current requirements, and aligning your paperwork with them is far cheaper than arguing about a kept deposit after the fact.
Why the discipline pays in January
Three practical reasons to care beyond correctness. First, without this treatment your December profit and loss overstates the truth and January understates it, which distorts every margin and comparison exactly when you are planning the year ahead. Second, the cash is not really yours to spend: the gift-card float and the deposit pool must still be deliverable against, and a business that spends the float in December meets its redemptions in January with strained cash and thin stock. Keeping a running view of the outstanding liability, and making sure working capital comfortably covers it, is the operational half of the discipline. Third, clean unearned-income records make your BAS, your year-end and any due diligence dramatically easier, because the numbers reconcile instead of requiring a story. It is a small piece of the broader hygiene that makes the rest of your finance function trustworthy.
A note on the moving parts
The principle here is stable: cash received is not income earned, and the books should say so. The specifics around GST attribution, deposit forfeiture and gift-card validity are the parts that shift, so treat this article as the map rather than the territory. The ATO and the ACCC hold the current detail, and your accountant can apply it to the particular ways your business takes money in advance.
