Why your dates can differ
Your due dates depend on how you report, for example monthly or quarterly, whether you lodge through a TPB tax agent, and your own circumstances. Dates can also move when they fall on a weekend or public holiday.
That is why we confirm your dates when we first speak, and keep you on track from there.
