The standard allowance for 2026/27
The standard amount is £12,570. You share it across your income; you do not get another allowance for each job.
When it is reduced
Adjusted net income above £100,000 reduces the standard allowance by £1 for every extra £2. It reaches zero at £125,140. Other adjustments can also affect your tax code.
