We're all about delivering top-notch service levels through one awesome brand. Trust us, this is a game-changer for everyone in the self-employed and business community!

We help the doers and the makers

For accountancy, tax and umbrella payroll employment solutions, no one does it like Caroola

The self-employed: they’re the beating heart of our economy. Which is why, when it comes to providing people-first, tech-empowered accountancy, tax and umbrella payroll solutions, Caroola has the success of every single one of them at heart.

And central to that success is our brilliant team of experts who make up the Caroola Crew. Always fired up to make the numbers work for our clients, so they can make the most of their careers.

Our services

We help make people’s money work 

The world of work is changing for our millions of contractors, freelancers, sole traders and small business owners. Which is why, to ensure the workforce we support not only remain flexible but also have everything they need to help them be more successful, Caroola provides people-first, tech-enabled services.

It’s not just about providing the best accountancy services for sole traders and those who work for themselves; it’s about freeing up their time so they can do what they do best. Along with self-assessment, VAT returns, filing, payroll and HMRC matters, our expert accountants also advise on expenses and maximising earnings.


We’re not just a go-between for contractors and recruiters. We’re a human point of contact who handle payroll including PAYE, income tax and NI contributions—making life a lot easier for temporary workers. And as employees of our umbrella payroll solutions, those workers get the benefits that fully employed staff would enjoy including holiday, sick and maternity pay, income protection and insurance as well as a range of flexible benefit options.


Our customers work hard. So we help them maximise their earnings with the minimum of fuss. Our work includes making tax returns a breeze and arranging tax rebates—all whilst staying on the right side of HMRC. And when it comes to tax advice, we always have real people on hand to answer any queries.
