If you’re a sole trader or landlord, tax season can seem overwhelming. After all, there’s a maze of forms, deadlines and calculations to get to grips with – and that’s before the Making Tax Digital changes come into force next April.

This will see digital record-keeping become essential. So, it’s never been more important to choose the right Self Assessment tax software. It’s not just about having a convenient solution but also being confident and compliant in it too. So which tax software is right for you? Let’s break it down. 

The challenge

Whether you’re running a business or managing tenants, you likely don’t have time to spend hours on spreadsheets. And even if you did, who would want to? That’s why you need tax software that makes your life easier, not more complicated. In fact, the best software should help you:

Sounds good, right? That’s where GoSimpleTax comes in.
