Notes:

*Company tax returns must be submitted online. 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” or “very large” should make their instalment payments by the relevant due dates. Corporation Tax must be paid electronically.
***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. From 1 April 2019, businesses with turnover exceeding the VAT registration threshold (currently £85,000) must also meet the requirements of Making Tax Digital (“MTD”) for VAT in respect of their first VAT return period beginning on or after 1 April 2019. For some businesses, MTD for VAT is deferred and does not commence until 1 October 2019.
****Deadline is extended to the 22^nd for electronic payments; such payments must reach HMRC’s bank account by no later than the last bank working day before the 22^nd day of the month (unless paying by Faster Payment) or 19^th for non-electronic.
