financial statements
and corporation tax

Your company is required to report its financial position to HMRC and Companies House on an annual basis. Our UK-based SME accountants are on hand to help ensure all your filing obligations are met.

Your year-end financial statements should cover your past financial year and declare your Corporation Tax Liability. Here, we can help you in the following ways:

  • Preparing your annual year-end financial statements
  • Submitting them to HMRC and Companies House
  • Preparing your Corporation Tax return and its supporting workings
  • Sending the electronic submission to HMRC
  • Preparing your audit file in preparation for your end-of-year audit (if required)

We will help you to meet this filing obligation and review your accounts with you. This will also help us to advise you of any changes that you can implement to increase your tax-efficiency.
