Your dedicated accountant will get to know your business accounting needs especially when it comes to Contracting. They provide you with personal advice on how to maximize your take-home pay, file your accounts and tax returns to HMRC dealing with any query or problem that may arise in the day to day running of your business.

The change from permanent employment to contractor

Having a dedicated accountant and the invaluable advice that they provide will make the decision from moving from permanent employment to working as a contactor smoother. Although this process can be rewarding, allowing you to have more take-home pay, greater job satisfaction and independence, it can be fraught with confusion. The IR35 minefield is tricky but 1Stop Accountants and their team of dedicated accountants will expertly guide you through this process with their many years of IR35 Contracting Accounting experience.

Bringing traditional accounting services into the modern world

You might be thinking, if I have this great online software, why do I need an accountant?
1Stop Accountants use this online software only as a tool bringing traditional accounting services into the modern world. However, managing your accounts can be tricky and questions always crop up so we provide all our Contractor Clients with a personal service from a dedicated accountant.

The IR35 minefield

In simple terms, IR35 is a set of rules that decide if you can class yourself as a contractor, or if you are still an employee. If HMRC decides you’re an employee, you’ll lose the benefits of being a contractor, such as higher take-home pay.
1Stop Accountants will provide you with all the benefits of being a contractor without the IR35 pain. Our IR35 expert accountants will be on hand to advise you on how to conduct your business as a contractor and not be deemed an employee by HMRC. Hence ensuring that you maintain all the benefits of being a contractor without having to worry about IR35 rules.
