When you’re self-employed, it’s important to understand how much you can earn before paying tax and the various allowances and reliefs that are available to help lower your tax bill.
The answer of how much you can earn before you pay tax isn’t a set figure and is dependent on a variety of factors including total income, how your income is structured and whether you operate as a sole trader or limited company.
In this post we’ll explore the key allowances, thresholds and the factors that determine how much you earn before you start paying tax in the UK.
The Personal Allowance
The key starting point is the personal allowance which is the main tax-free amount you can earn each tax year before you become liable for income tax.
For most taxpayers, including sole traders and limited company contractors as well as those in conventional employment paying tax through PAYE, this amount is £12,570 per year.
This means you can earn up to £12,570 in taxable income before income tax is levied and any earnings above this threshold will be taxed at the relevant rate based on total taxable income.
The personal allowance applies across your total taxable income, including sources such as:
- Salary
- Trading profit from self-employment
- Dividends from limited company profits
- Other taxable income sources
The Trading Allowance
HMRC also provides a trading allowance which means you can earn up to £1,000 per tax year from self-employment or casual trading without registering for self-assessment or paying tax on the income.
This allowance is in place to benefit those with very small or occasional income streams such as earnings from side hustles or hobbies.
- Income under £1,000 may be tax-free
- Once you exceed £1,000, you must report your income to HMRC
- The trading allowance doesn’t apply if you claim business expenses on the same income
- This allowance is not designed for contractors or those in full-time self-employment
For sole traders, this allowance can be relevant at the very early stages but as your business income grows and exceeds the threshold, it will no longer apply and you must report your earnings to HMRC and pay tax.
The Dividend Allowance
If you run your own limited company, you can also benefit from the dividend allowance which enables you to receive some dividend income each year tax-free.
- £500 of annual dividend income is untaxed
- Dividends above this threshold are taxed at the normal dividend rates, although it can be tax-free if it falls within the personal allowance
Dividend tax rates are lower than income tax rates which is why many directors incorporate dividends into their remuneration strategy.
However, dividends can only be paid if your company has sufficient retained profit and they must be properly documented with dividend vouchers and board meeting minutes to remain compliant.
How These Allowances Work Together
The personal allowance, trading allowance and dividend allowance can all be used in the same tax year, but they apply to different types of income so don’t combine together into one tax-free pool. Instead, each allowance applies in a specific way dependent on the income type and the order in which tax is calculated.
- The personal allowance applies first and applies to overall taxable income so can cover multiple income sources including dividends
- The trading allowance applies specifically to small amounts of self-employment income under £1,000
- The dividend allowance applies to dividend income only
The personal allowance can therefore provide tax relief across multiple income sources whereas the dividend and trading allowances only apply on specific income types. But the interaction depends on the structure of your earnings. For example, if you receive a salary of £10,000 and £20,000 in dividends, £2,570 of those dividends would be tax-free under the personal allowance, with an additional £500 untaxed thanks to the dividend allowance.
Income and Dividend Tax Bands and Rates in the UK
Once your taxable income exceeds any applicable tax-free allowances, it is taxed using standard income tax bands:
- Basic Rate: £12,571 to £50,270 – 20%
- Higher Rate: £50,271 to £125,140 – 40%
- Additional Rate: Over £125,140 – 45%
Understanding which band you fall into is essential for estimating how much tax you will pay, helping you to plan ahead to cover your tax liability.
Dividend income is taxed using the same income tax bands, but with lower tax rates applied:
- Basic Rate Band:75%
- Higher Rate Band:75%
- Additional Rate Band:35%
It’s important to note that your total income, including dividends, determines which tax band you fall into. Dividend income is then taxed at the corresponding dividend rates within those bands after any allowances have been applied with many directors structuring their income to benefit from the lower dividend tax rates.
Limited Company vs Sole Trader: How Tax Works
The amount you can earn before paying tax depends, and the overall amount of tax you will pay, depends on whether you operate as a sole trader or through a limited company, and how effectively you implement tax optimisation strategies.
Sole Traders
As a sole trader, you:
- Pay tax on business profits, not owners drawings
- Your income is subject to income tax and class 2 and 4 NICs
- The personal allowance applies against total taxable income
- Tax is simpler but often less flexible as sole traders can’t receive dividends
This means that once profits exceed the £12,570 personal allowance, you pay tax on profits above that level plus NICs based on earnings.
Limited Company Directors
Tax is more complex for limited companies, but there is also more flexibility and more scope to implement tax planning strategies to lower your tax bill.
- The company pays Corporation Tax on taxable profit
- Directors are taxed personally only on what they take out
- Income is usually split between salary and dividends which are taxed separately
This creates two layers of taxation:
- Corporation Tax (paid by the company)
- Personal tax (paid on salary and dividends received)
Many directors will take a smaller salary to maximise the benefit of the personal allowance and pay lower NICs, and supplement their income with dividends which enables them to extract profits from the business more tax-efficiently due to the lower dividend tax rates.
National Insurance Contributions (NICs)
Even if your income is below the income tax threshold, you may still need to pay National Insurance, as NIC thresholds differ from income tax thresholds and depend on how your income is earned.
Sole traders may pay:
- Class 2 NICs depending on profit levels
- Class 4 NICs which are charged based on business profits
Limited company directors may pay:
- Employee NICs on salary through PAYE
- Employer NICs, which are paid by the company on salary
NICs are separate from income tax but can have a significant impact on overall take-home pay, particularly as income increases.
For directors, this makes tax planning especially important. By carefully structuring salary and dividends, it’s possible to reduce overall NIC exposure as dividends are not subject to NICs.
Tax Reliefs
In addition to main allowance, various tax reliefs can also be utilised to reduce the amount of income or profit that is exposed to tax, such as
- Allowable expenses
- Pension contributions
- Capital allowances
- Marriage allowance
- Gift aid
- Working from home relief (where eligible)
These reliefs are subtracted from your profit to determine your taxable profit which is the amount against which your tax is calculated, so the lower your taxable profit, the less tax you’ll have to pay.
