Question 1

How is self-employment income taxed in the UK?

Accepted Answer

Self-employed sole traders pay Income Tax on their trading profit (revenue minus allowable expenses) and Class 4 National Insurance at 9% on profits between £12,570 and £50,270, then 2% above. Class 2 NI is £3.70 per week if profits exceed £6,725.

Question 2

What is the £1,000 trading allowance?

Accepted Answer

The trading allowance lets you deduct a flat £1,000 from your revenue instead of itemising expenses. It is beneficial when your actual business expenses are less than £1,000. You cannot claim both the trading allowance and itemised expenses.

Question 3

Do I need to pay Class 2 National Insurance?

Accepted Answer

Class 2 NI is £3.70 per week (£192.40 per year for 52 weeks) if your annual trading profit is at or above the Small Profit Limit of £6,725. Below this threshold, Class 2 is voluntary.

Question 4

Can I reduce my self-employment tax bill with pension contributions?

Accepted Answer

Yes. Personal pension contributions reduce your taxable income and your Adjusted Net Income. If you earn over £100,000, pension contributions can restore your Personal Allowance and avoid the 60% tax trap.

Question 5

Do I need to file a Self Assessment tax return?

Accepted Answer

Yes, if your self-employment income exceeds £1,000 (the trading allowance). You must register with HMRC and file a Self Assessment return by 31 January following the end of the tax year. The deadline for paper returns is 31 October.
