Income tax for sole traders

Income Tax for sole traders is calculated based on self-employment income (minus disallowable expenses). Every UK resident is entitled to a personal tax-free allowance before their income is taxed, so you’ll need to deduct it from your overall income to determine what your taxable income is.

The current Income Tax rates for sole traders are:

  • Personal allowance: the first £11,850 = tax-free.
  • Basic rate tax: the next £34,500 = 20% tax
  • Higher rate tax: between £34,501 and £150,000 = 40% tax.
  • Additional rate tax: the next £150,000 = 45% tax.
  •  

When taxable income exceeds £100,000, the personal allowance rate reduces by £1 for every £2 of income above this level.

The deadline to file a tax return is 31st of January.


Sole Trader National Insurance Contributions (NIC)

Sole traders are currently required to pay two forms of National Insurance Contributions: Class 2 and Class 4. During your Self Assessment, for Class 4 you must calculate the amount you owe based on your profit, whereas for Class 2 you must pay an amount based on a fixed rate charge.

Class 4 NIC:

  • The first £8,424 = 0%.
  • The next £46,350 = 9%
  • Income above £46,350 = 2%.

Class 2 NIC:

  • A fixed rate charge of £2.95 per week.
  • When a business earns below £6,205 per annum, they can claim exemption due to being below the small income threshold.
  • Class 2 NIC is due to be scrapped in April 2019.
