Alles over Freelancer Tax Calculator
📋Overzicht+
Self-employed freelancers pay income tax on trading profit (income minus allowable expenses) at the same personal rates as employees, plus Class 4 National Insurance on profits above the lower profits limit. Instead of deducting actual expenses, you can use the £1,000 trading allowance if that gives a better result. Student loan repayments (Plan 1, 2, 4 or 5) are calculated on profit above the relevant repayment threshold and added on top of income tax and NIC.
💡 Best practices
- If your actual expenses are under £1,000, the trading allowance almost always beats deducting real costs.
- Class 4 NIC is calculated automatically through Self Assessment alongside income tax — budget for both together, not just the headline income tax rate.
- Student loan repayments are a flat percentage of profit above the threshold, not linked to the loan balance — check which plan applies to avoid over- or under-paying.
🔢 Concreet voorbeeld
£45,000 trading income with £8,000 allowable expenses, no other income, Plan 2 student loan: £37,000 taxable profit generates income tax, Class 4 NIC and a 9% student loan repayment on profit above the Plan 2 threshold.

FAQ — Freelancer Tax Calculator
Do I pay Class 2 NIC as well as Class 4?+
Class 2 NIC was effectively abolished for most self-employed people from 2024/25 (voluntary payments remain available to protect state pension entitlement) — this calculator focuses on the compulsory Class 4 charge.
Can I claim both the trading allowance and specific capital allowances?+
No — using the trading allowance replaces all expense and capital allowance claims for that income; if you have significant equipment costs, deducting actual expenses is usually better.
