What this salary means
£100,000 is the Personal Allowance taper boundary
£100,000 is a key UK tax threshold. Adjusted net income above this point starts reducing the standard Personal Allowance by £1 for every £2 of excess income, so pension and salary-sacrifice decisions can have unusually large tax effects above this level.
The Personal Allowance taper starts above here
£100,000 is a key UK tax threshold. Adjusted net income above £100,000 begins to reduce the standard Personal Allowance by £1 for every £2 of excess income, so the next part of a pay rise can be taxed unusually heavily.
