Notes:

*Company tax returns must be submitted online for accounting periods ending after 31 March 2010. Tax computations and (with few exceptions) accounts forming part of a company tax return, must be submitted in iXBRL format.
**Small companies are those not required to make corporation tax payments in instalments under the Instalment Payments Regulations. Companies classed as large under this should make their instalment payments by the relevant due dates. Corporation Tax must be paid electronically.
***Paper filing deadline may be extended if the taxpayer’s circumstances warrant that an online self-assessment return cannot be completed due to various exclusions published by HMRC. Such paper returns filed by 31 January 2019 will be treated as having a reasonable excuse if accompanied by a reasonable excuse claim.
****Virtually all VAT-registered businesses must submit online VAT Returns and pay any VAT due electronically. In this situation, the return and payment deadline is 7 days later than normal, as noted above. The 7 calendar day extension does not apply in certain exceptional cases.
*****Deadline is extended to the 22nd for electronic payments; such payments must reach HMRC’s bank account by no later than the last bank working day before the 22nd day of the month (unless paying by Faster Payment) or 19th for non-electronic.
