GST-inclusive and GST-exclusive amounts
For an invoice, the GST tool separates the underlying price from the tax. Check whether the quote says inclusive or exclusive before entering it. Zero-rated and exempt supplies need their own classification; selecting either does not establish eligibility. If the same document contains differently treated supplies, separate those amounts instead of forcing a single rate over the complete payment.
PAYE and other deductions from earnings
The income calculator includes PAYE, ACC and student-loan scenarios within its stated tax-year coverage. Use earnings for the period requested and identify which deductions apply to your situation. The tax assessed on income and the resulting cash pay are different outputs. A forecast for a regular period may not reproduce a payslip with corrections or irregular payments; check the guide before comparing only its net figure.
