Why use our self-employed and employed tax calculator?

If you are self-employed and employed, our calculator gives you a clear view on your annual income tax, National Insurance Contributions (NIC) and total personal pension payments, helping you plan your finances with confidence. As well as this, you can find out how your income, tax status, and pension contributions might affect what you actually take home.

What is my take-home pay?

Your take-home pay is the amount of money that lands in your pocket after tax and any other deductions, such as NIC and any pension contributions you make. Whether you’re employed, self-employed or both understanding these deductions can help you manage your finances more confidently.

How our calculator works

To work out your results, our calculator assumes a few things:

    Income Tax FAQs

    How do I calculate my taxable income?

    Your taxable income is your total earnings minus any allowable expenses, tax-free allowances, and pension contributions. It’s the amount HMRC uses to work out how much tax you owe.

    What are allowable expenses for self-employed individuals?

    Allowable expenses are costs that are essential to running your business, like office supplies, travel, equipment, and professional services. These can be deducted from your income to reduce your tax bill.

    When and how do I pay my tax bill?

    Self-employed people usually pay tax through Self Assessment, with payment deadlines of the 31st January and 31st July. You can pay online, by bank transfer or through your HMRC account.
