5. Frequently Asked Questions (FAQ)

Q1: Why is my tax code important?
A: Your tax code determines your tax-free allowance. The standard code is 1257L (£12,570 tax-free), but other codes may apply if you have additional income or benefits.

Q2: How accurate is this calculator?
A: It provides a good estimate but doesn't account for all possible deductions or tax situations. For exact figures, consult your payslip or accountant.

Q3: When do student loan repayments start?
A: Repayments begin the April after you leave university/college, but only when your income exceeds the threshold for your plan.

Q4: Is pension contribution mandatory?
A: Workplace pensions are auto-enrollment schemes, but you can opt out. The minimum contribution is 5% from you (plus 3% from employer).

Q5: Why is National Insurance separate from Income Tax?
A: NI funds specific state benefits like the State Pension, while Income Tax goes into general government spending.
