- Set up your worksheet: Create cells for income, pension contributions, charitable donations, and other deductions.
- Calculate taxable income:
=Income - PensionContributions - CharitableDonations
- Apply personal allowance:
=MAX(0, TaxableIncome - 12500)
- Calculate tax for each band:

=IF(WeeklyIncome <= 183, 0, IF(WeeklyIncome <= 962, (WeeklyIncome - 183) * 0.12, (962 - 183) * 0.12 + (WeeklyIncome - 962) * 0.02 ) ) * 52 - Calculate student loan repayments:
