Being self-employed means that you work for yourself rather than an employer.
We know that the accounting side of being self-employed isn’t always straight forward, which is why we’re breaking it down for you!
You can thank us later. 😜
Here’s some simple steps of what you’ll need to do when self-employed:
First, you’ll want to register as a sole trader. You may be wondering, ‘how do I do this?’
Luckily for you, we’ve written a step-by-step guide to registering as self-employed. Check this out here.
But that’s not all, we’ve also answered all the most common questions related to setting up as a sole trader – you can check this out here if needed.
FYI: If you decide you no longer want to work for yourself, you’ll need to let HMRC know so that they aren’t expecting you to file a tax return.
When you register as self-employed, you are given the option between cash basis and traditional accounting.
Choose whichever method works for your business. Cash basis is generally the easiest option as you simply track what goes in and out of your bank account.
Traditional accounting may work for bigger businesses.
Get into the habit of separating your personal and business finances as soon as possible.

Keep records for at least 5 years.

The tax year is a point of confusion for many. Unlike the calendar year, the tax year runs from April to April. If you’re a LTD company, your business “year” can take place during any 12 month period of your choosing, meaning your filing deadline is unique to you and your business.
As a sole trader, things are a little simpler. Take a look at the below table for the important dates and deadlines to get in your diary for the current tax year.
