A tax invoice is no use to them because they can't claim the GST back via input tax credits. And if they're PAYE taxpayers they feel that they're already shouldering an unfair burden. You are expected to withhold 48 per cent. It's business as usual. People in the cash economy just smile at you and say, 'the Government doesn't have a clue how much goes on outside the system'.
People feel cheated.
They feel that the tax cuts have not really compensated them. It's costing them more, especially on house renovations, and they don't think there's anything wrong with it. Building tradesmen offer discounts for cash on small jobs, but bigger jobs require warranty insurance, approvals and certification. According to John Gaffney, boss of the Housing Industry Association, home renovators can get around the GST without using unlicensed cowboys by pretending to be owner-builders. You still get a builder to manage the project but it enables you to deal direct with the sub-contractor.
