🧾 Tax & running a business — the structure of what leaves your till each month

Calculate it yourself

Monthly checklist

• Do you know your ABN/GST status and BAS cycle (quarterly or monthly)?
• Is payroll reported through STP, with super paid on payday (Payday Super)?
• If you pass card fees to customers, do your price displays and terminal settings match the current rules?
• When minimum wages and allowances update, did you recalculate your pay structure?
• Have you decided where, how long and when you dispose of customers’ ID copies and other personal data?
• Are business and personal accounts separated?
• Are invoice currency and payment terms with Korean counterparties written down?

Checks are not saved. Keep your own notes.
