Sole trader tax calculator

What is the sole trader tax tool?

Designed specifically for sole traders, the tax tool gives you a profit and loss statement based on the transactions in your Starling business account. What’s more, you’ll also see an estimation of your tax liability for the self-employment part of your self-assessment tax return. And to make sure you’re ready when the time comes, you can create a Savings Goal to set aside money for your tax bill in a matter of clicks.

How does the sole trader tax tool work?

Start by making sure we have the correct information about you - including your tax region, any student loan plans, and national insurance details. All looks good? Then you can use the sole trader tax tool to see a profit and loss statement (based on transactions in your Starling account and any that you’ve manually added in the Bookkeeping section), with an expenditure breakdown that maps directly to the SA103F form (the self-employed part of your Self-Assessment Tax return). The allowable income or expenditure is automatically set based on the business spending category assigned to a transaction - you can change the category and the allowable tax amount for a transaction in the Bookkeeping section, which all feeds into the Tax tool. You can also view estimates of your tax liability and save up towards it using Goals.
