As a self-employed person or small business, you will be required to file certain information with HM Revenue & Customs (HMRC) and Companies House. Failure to do so can result in late filing and late payment penalties, fines and interest on late payment.

This monthly schedule of important deadlines in the tax year will help you prepare and send off the main forms in good time so you can avoid the penalties.
