Inheritance Tax administration and time limits
As will be familiar to many, the IHT return is due within 12 months of the end of the month in which the death occurred (although IHT is payable six months earlier). Typically (COVID aside), HMRC raise queries within about 12 weeks or at least advise they will be sending questions. They proceed to send the questions within another eight weeks and these will take the form of an informal enquiry.
With other direct taxes there are mechanisms for HMRC to open formal enquiries. Whilst these can be incredibly stressful and time consuming, one of the benefits of formal enquiries is that if the investigation does not appear to be going anywhere then the taxpayer (or their adviser) can request the enquiry is closed. This request can go to the tax tribunals if necessary. With an informal investigation, there is no such protection.
The legislation requires HMRC to raise assessments within a certain number of years, based on the “behaviour” of the taxpayer – four years if the taxpayer (here, the executor of the estate) took reasonable care, six years if they were careless or 20 years for cases of fraud (for UK taxes). This applies to IHT only where the IHT return was filed.
Where no IHT return is filed, then there are no time limits if the individual responsible for filing the tax return deliberately failed to do so. If it was not deliberate, but there was a lack of reasonable care, then HMRC has 20 years to raise an assessment.
Information notices
To carry out enquiries and investigations, HMRC has a number of tools at its disposal. One of the most powerful is its information powers. Broadly speaking, HMRC is permitted to request any information relating to the taxpayer’s present, past or future tax position provided there is an open enquiry for the period the documents relate to. If there is no open enquiry, HMRC must have reasonable suspicion that there is a tax loss.
We often come across information notices where HMRC has not complied with the requirements but the taxpayer has provided information regardless. Also, although there is no right to refuse provision of statutory records (subject to other criteria being met), you may qualify for legal or litigation privilege.
Beware informal requests for information as they may not be safeguarded by the requirements in the Information Powers legislation and therefore there may not be legislative ground on which to deny the information. It may be useful to ask HMRC to request the information formally, though you would need to weigh up the associated consequences.
If HMRC ask informally and no information is provided, then they will use their formal information powers. This could then affect the penalty levied (if any) on the basis that full cooperation was not given by the client from the beginning. Any refusal to provide information should therefore be carefully thought through and justified.
