TaxKernel Wants Tax Law to Come With a Replay Button

Field notes

The homepage illustrates its proposed certificate format with the au-2025-26 ruleset, a resident individual earning $98,000, and three ordered rule firings. Those steps cite Australian legislation for base tax, the Medicare levy, and the low-income tax offset before producing a $22,148 result. The service says yearly rulesets remain immutable while amendments arrive as versioned diffs, and links to an open verifier, API documentation, a ruleset changelog, and status information.
