EGL73000 - Administration of EGL: quarterly instalment payments
Large or very large companies are required to pay CT by instalments in advance of the standard payment date of nine months following the end of an accounting period. F(2)A23/S306(3) ensures that liability to EGL is taken into account when considering whether a company is required to make instalment payments. It does this by providing that the requirement is met when either the company’s CT profits or its exceptional generation receipts exceed the relevant “profits” threshold in the Instalment Payment Regulations.
F(2)A23/S306(4) & (5) deal with the commencement of the levy. Any EGL liability in relation to the period from 1 January 2023 to the date the Finance Bill receives Royal Assent is to be included in the first instalment due after that date.
The Taxation (Energy and Vehicles) Act 2026 introduced an increase in the levy rate from 45% to 55% for receipts attributable to electricity generated on or after 1 July 2026. Where a large or very large company is required to make quarterly instalment payments, the increase in EGL liability resulting from that change did not need to be reflected in payments made before the Act received Royal Assent on 15 July 2026. The affected EGL liability must be included in the first instalment due after 15 July 2026. Interest applies accordingly.
