Introduction
Change of Accounting Reference Date
- In this example, we consider the year-end date to be 31 March 2020.
 - This is extended to 30 September 2020.
 - This is the maximum period allowed i.e. by 6 months.
 - One cannot have an accounting period of more than 18 months. Companies House filing deadlines will be extended by 6 months.
 - The table gives the implications below.
 - HM Revenue & Customs filing deadlines will also change.
 - This will apply to submission of Corporation Tax computation and returns.
 - It will also apply to HM Revenue & Customs change of deadlines for payments.
 - No further extensions of the accounting period will be allowed in the next 5 years.
 - Starting from the date when the form to change the year-end is filed with the Companies House.
 - It will be possible to shorten the year-end, if required.
 - This will also extend the time to get the audits completed, as well.
 - The biggest benefit would be that the 12 months profit would be determined on a time apportionment basis i.e. 12/18 of the results.
 - On the assumption that the next 6 months will be loss of very little benefit, it will be averaged out over 18 months.
 - Further, the subsequent 12 months, if it produces lower taxable profits, it will give rise to lower tax bills.
 - It should give rise to lower tax liabilities over the next 3 years, at least.
 - The filing/payment deadlines will be changed as follows:
