One source of truth for every disclosure

St8tax uses your payroll data as the single source of truth — the same data used for ATO Single Touch Payroll (STP) reporting. This means every disclosure is accurate and up to date.

Upload your payroll files and calculate all monthly payroll tax disclosures across every state with one click. St8tax replaces manual spreadsheets with a controlled, automated and fully auditable process that delivers consistent, reliable results every month.
