When you have both employed and self-employed income, all your income is added together to determine your tax band. Your Personal Allowance is used against your employed income first.
Income Tax: Calculated on your combined income after deducting the Personal Allowance and any allowable expenses.
National Insurance: Employee NI (Class 1) is calculated only on your employed salary. Self-employed NI (Class 2 and Class 4) is calculated only on your self-employed profits.
Self Assessment: You must submit a Self Assessment tax return if you have self-employed income over £1,000.
