This update introduces a new rule for calculating superannuation guarantee payments in Australia, aligning with Australian Taxation Office (ATO) requirements. Specifically, it incorporates 'Qualifying Earnings' (QE) as the primary source for superannuation contributions, replacing previous calculations from Ordinary Time Earnings (OTE) starting July 1st, 2026. This ensures accurate and compliant superannuation reporting.

Added new salary rule for Qualifying earnings.
