Self-Assessment Tax Return


Completing a Self-Assessment can be an overwhelming task – there are some complicated procedures involved, and it is hard to complete on your own. This has to be filled by anyone who is self-employed, included those who are contractors or owners of limited companies.

The Self-Assessment is a system that is utilised by HM Revenue and Customs (HMRC) to collect Income Tax in the UK. While it may be typically deducted automatically from wages, savings and pensions, individuals and business with other income types are obligated to report it in an annual return.

A self assessment is required by anyone who is a self-employed, whether you are a contractor or registered as a limited company. It is one of the most significant documents that your business will need to complete, and if not completed correctly it can have an impact on the revenue of your business. We can help you with your submission.

The process can often appear to be complicated and many business owners and contractors often require support through the process. Our team have the expertise to manage this process for you.

The process involves registering for a self assessment on the registration page. Once you are registered you will receive a gateway ID which will allow you to set up a personal tax account and file your return. The deadline for submission is 21 January 2020.
