Jim Chalmers has been caught out by his own tax office. They’ve made a pretty revealing admission: absorbing the cost of accepting credit cards is “not tenable”. In other words, the cost doesn’t magically disappear when you ban the surcharge. The ATO collects $700 billion in tax every year, yet even it won’t absorb the cost. But Labor expects the local café, tradie and family business to wear it. The surcharge might disappear from the receipt but the cost doesn’t. Small businesses should still be able to pay their tax by credit card to manage their cash flow. The Prime Minister should have reversed this decision yesterday.
