Simple vs Complex

Understanding the way our fees are calculated

Simple or Complex Estate?

UK Probate’s fixed fees are driven by the forms HMRC require us to complete on your behalf.

HMRC have two different forms for Inheritance Tax purposes.  Every estate has to complete one of these forms even if there is no tax to pay.

We use the forms to classify estates as ‘Simple’ or ‘Complex’.  An estate classified Complex may not seem that complicated, and have only a few assets, but the requirement from HMRC to use the full IHT400 (to claim the Residence Nil Rate Band, or if there is a Trust or Foreign Assets) make the estate naturally more Complex.

Simple Estates

HMRCs definition of a Simple Estate (Excepted Estate) and criteria to use form IHT205 are as follows:

Gross value of the estate for Inheritance Tax is less than or equal to:

  • the excepted estate limit (£325,000)
  • twice the excepted estate limit (£650,000) and form IHT217 ‘Claim to transfer unused nil rate band for excepted estates’ is used (we complete this for you)
  • £1million and there is no Inheritance Tax to pay because of spouse, civil partner or charity exemption

Complex Estates

All other estates require the full IHT400 which has lots of schedules and attachments, and is sent to HMRC before the Probate Registry (unlike the IHT205).  We classify all estates that require the IHT400 as Complex Estates for our pricing plans.
