A tax mechanism can stay familiar while its thresholds or eligibility rules change. A useful reference therefore needs a year, jurisdiction, conditions and source.
The values on this page were checked against the linked official sources on 5 September 2026 for 2026/27 (6 April 2026 to 5 April 2027). This is a source check of the listed figures, not a personal financial assessment or a promise of automatic future updates.
Other lessons use dated examples too. Their dependencies must be reviewed with this reference when a Budget, commencement or new tax year changes the rules. Check current official guidance before acting; a matching year alone does not establish that a rule fits your circumstances.
