  • Behaviours that contribute to the tax gap

    Measuring the small business income tax gap is showing us that the small business population can be broken into three groups:

    • those inside the tax system
    • those outside the tax system
    • those inside the tax system some of the time.

    Results from our random enquiry program show that most small businesses are paying the right amount of tax – but some are making mistakes and some are avoiding paying the right tax.

    Some businesses make the odd mistake, but only a small percentage deliberately avoid paying the right tax. It’s this smaller group that contributes most significantly to the tax gap.

    We estimate that over $7 billion (or around 64% of the total gap) can be attributed to black economy behaviour. This includes small business taxpayers deliberately under-reporting their income, exaggerating business expenses or operating completely outside the tax system.
