How it works
We take your gross income and subtract allowable expenses to find your taxable profit. We then apply the Personal Allowance (tax-free amount), followed by the Basic (20%), Higher (40%), and Additional (45%) income tax bands. We also calculate Class 4 National Insurance (6% or 2%) and check if voluntary Class 2 applies.
