Method

How the radar is controlled

Official-source first

Each item links to the authority, legislation or institutional source used to verify the stated stage and timing.

No silent legal inference

Announced proposals are not presented as enacted law. Signature, enactment, entry into force, effective date and guidance are kept distinct.

Action over volume

Urgency reflects the proximity and materiality of the practical consequence. It is an editorial prioritisation tool, not individualized tax advice.
