In Hargreaves v HMRC [2019] TC07090 HMRC's long delay in raising an assessment on an £84m capital gain meant that there was no 'discovery' and it was invalid.

Mr Hargreaves initially claimed he was non-resident, he dropped that and claimed that the conditions for a discovery assessment had not been met.

The FTT considered:

It found:

There were more than three years between HMRC making a discovery that the taxpayer was non resident and raising an assessment. A discovery cannot be remade: the discovery had lost its quality of newness and become stale by the time the assessment was made.

Accordingly the assessment could not stand.

Having found that, the outcome of the further discovery conditions was immaterial, all of which were found in HMRC's favour:

Comment

Two other cases on discovery and staleness went on appeal to Court of Appeal: Tooth and Beagles. The judgment in Tooth is expected any day and Beagles is to be heard later in 2019. It is expected, given the amount of tax involved that HMRC may appeal Hargreaves. Time limits for discovery assessment in cases involving offshore matters are now extended to 12 years in normal cases.
