Stumped by Self Assessment? Grab our guide

The Crunch Personal Tax Estimator will help you plan by calculating the tax you owe or may have to pay on your personal income including from sole trade income, salary from employment, dividends and other sources.

Please note that the Crunch Personal Tax Estimator is a simple UK tax calculator and will only provide an estimate of your tax liability. It’s designed to show you the tax-efficient amount of income (for instance a combination of salary and dividends) you could take from your limited company based on the information you enter. It can help you to plan to pay any tax due on this income. There are different versions based on whether you’re a resident of England, Wales, Scotland, or Northern Ireland.

The Personal Tax Estimator is pre-populated to show default amounts for salary (set at the relevant National Insurance threshold) and dividends (set at the basic rate dividend threshold for the relevant tax year). You can amend these amounts if you need to based on your personal circumstances.

Using our free Crunch Personal Estimator can help you calculate what tax you’ll need to pay in your Self Assessment. In addition to salary and dividend income you can also add other figures to the Crunch Personal Tax Estimator:

  • Salary from employment outside your company: Add the gross salary to the PAYE Income field, and the tax paid on this income to the PAYE Tax paid field.
  • If you need to estimate the tax on this income you can do so by leaving all other fields blank.
  • If you have multiple employments just enter the total of all the gross income amounts into the PAYE Income box and enter the total tax paid on this income to the PAYE tax paid field.
  • Benefits in Kind: add the amount of taxable benefits in kind. Remember that only certain benefits on your P11D will be taxable (such as a company car or private healthcare).
  • Bank Interest: add the net amount you receive.
  • Sole-trade Profit: This field should be used if you carry out any work as a Sole Trader, this does not include any profits from your limited company (your income from limited company profit is usually taken as a dividend).
  • Other Income: Add any other income, such as profits from property rental, or interest received without tax deducted.
  • Pension Contributions: The amount you actually paid (or plan to pay) into your private pension pot.
  • Charitable donations: add any donations you made  (or plan to make) to a registered charity.
  • Student and Postgraduate Loans: If you are also making student loan or postgraduate loan repayments there is an option to select this and calculate an estimate of your repayments for that year which will be due at the same time as your Self Assessment tax return.

Self Assessment guide

At the bottom of the main calculation is a payment schedule, which will include payments on account if applicable. There’s an input box in this section for any payments on account you have paid for the tax year.

Estimating the tax you’ll pay if you’re a sole trader

If you’re a self-employed sole trader then you’ll need to remove the default figures entered for director salary and dividends and enter your estimated sole trader profit (all your income less any allowable expenses) in order to estimate the Income Tax and National Insurance you’ll need to pay. The final figure will be calculated by HMRC based on your Self Assessment. Depending on how much you earn, you may find that you could be better off as a limited company.
