Sections 73 to 79 of the Localism Act 2011 (c.20) made amendments to the calculations which billing authorities, major precepting authorities and local precepting authorities in England must make to determine their basic amounts of council tax for a financial year. Section 74 of the Localism Act 2011 inserted a new section 31A into the Local Government Finance Act 1992 requiring a billing authority to calculate its council tax requirement each financial year, and section 32 of the Local Government Finance Act 1992 became a provision applying to Wales only rather than to England and Wales. These Regulations make a minor amendment consequential on the changes made by the Localism Act 2011 to update the definition of ‘calculations’ in the Billing Authorities (Anticipation of Precepts) Regulations 1992 to refer to the new section 31A inserted by the Localism Act 2011.
