How self-employed tax works

As a sole trader or self-employed person in the UK, you pay three types of tax on your profits:

• Income tax at the same rates as employed workers (20% basic, 40% higher, 45% additional -- though Scotland has different rates)
• Class 2 National Insurance at £3.45 per week (£179.40 per year) if your profits exceed £12,570
• Class 4 National Insurance at 6% on profits between £12,570 and £50,270, and 2% above £50,270

Unlike employed workers who pay Class 1 NI at 8%, self-employed Class 4 NI is only 6%. However, you don't get employer NI contributions towards your state pension entitlement in the same way.

Expenses and the trading allowance

You can reduce your taxable profit by deducting allowable business expenses -- things like office supplies, travel, insurance, and professional services. Alternatively, if your expenses are low, you can use the £1,000 trading allowance instead. You can claim one or the other, not both.

On gross income of £165,000, your taxable profit is £164,000 (after the £1,000 trading allowance).

Payments on account

HMRC requires most self-employed people to make payments on account -- two advance payments towards your next year's tax bill. Each payment is 50% of your previous year's tax bill.

Based on a £71,493.71 tax bill, your payments on account would be:

• 31 January: £35,746.86 (plus any balancing payment for the previous year)
• 31 July: £35,746.86

This means in your first year of self-employment, you may need to pay up to £142,987.43 (the full year's tax plus the first payment on account). Budget carefully for this.

Self-employed vs employed

If you earned £165,000 as an employee instead in Scotland, you would pay:

• Income tax: £67,257.71 (same)
• NI (Class 1): £5,310.6 vs your Class 2 + 4 NI of £4,716
• Take-home: £92,431.69 (employed) vs £92,506.29 (self-employed)

As a self-employed person, you pay £594.6 less in National Insurance. However, employees also benefit from employer pension contributions and other workplace benefits. See the full employed take-home breakdown on £165,000.
