Self-Employed Tax Free Allowance UK – Allowable Expenses & Tax Savings Guide

Learn how to use self-employed tax free allowance and allowable expenses to legally reduce your tax bill and stay compliant with HMRC.

Running your own business as a self-employed individual comes with many advantages — including the ability to reduce your tax bill through self employed tax free allowance and smart use of self employed allowances.

At Audit Consulting Group, we help self-employed professionals across the UK understand what they can claim, how to stay compliant, and most importantly — how to keep more of what they earn.

Self-Employed Tax Free Allowance UK

Self-employed individuals in the UK can reduce their tax liability using personal allowance and allowable business expenses. Understanding these deductions helps you keep more of your income.

What Is the Self Employed Tax-Free Allowance?

In the UK, the self employed tax free allowance is the same as the Personal Allowance — the amount of income you can earn before paying income tax. For the 2025/26 tax year, it’s set at £12,570.

That means:

• You don’t pay income tax on the first £12,570 of your profits
• If your profits are below this threshold, you might not owe any income tax at all

We ensure our clients claim the full self employed tax free allowance while also guiding them on further allowable deductions.

What Are Self Employed Allowances?

Self employed allowances are additional deductions you can apply to reduce your taxable income. These include:

1. Common Self-Employed Allowable Expenses

If you use something for business purposes, you can likely claim it as an expense. Common examples include:

• Office supplies
• Business travel
• Phone and internet
• Software subscriptions
• Marketing costs
• Professional fees
• Home office expenses
• Equipment and tools

2. Simplified Expenses

HMRC allows flat-rate expenses for things like working from home or business mileage. You don’t need to calculate exact costs — just apply the set rates.

3. Capital Allowances

If you buy equipment or machinery for your business (like a computer or van), you can claim part or all of the cost under capital allowances.

4. Annual Investment Allowance (AIA)

Claim up to £1 million in eligible business equipment in a single year.

5. Trading Allowance

Earn up to £1,000 from self-employment or casual income without having to register for self-assessment.

We’ll help you decide whether to use actual expenses, simplified expenses, or a combination — to legally reduce your tax bill.
