HMRC has published an updated Inheritance Tax Toolkit effective for deaths occurring from 6 April 2010. Updates include emphasising the importance of providing HMRC with a copy of the will and any codicils when submitting the form IHT400.

These toolkits provide guidance on areas of error that HMRC frequently see in returns and set out the steps that you can take to reduce those errors.

The toolkits can be found here.
