IPT08490 | IPT audit assurance: IPT calculations: special accounting scheme
From HM Revenue & Customs · Insurance Premium Tax
Insurers must formally apply to use the special accounting scheme. Where an insurer has
adopted the special accounting scheme in practice and,
has used it consistently and properly but,
did not apply before starting to use it,
you should obtain a formal application from the insurer. The procedure is detailed in IPT10400.
This also describes how to deal with an insurer who applies to use the special accounting scheme from a future date; and requests by insurers to use the scheme with retrospective effect.
