HMRC has issued updated guidance reminding tax agents that estates cannot move between informal reporting and complex estate reporting once they have been registered for Self Assessment during the same administration period.
Where an estate initially qualifies for informal reporting but later becomes more complex, agents must register it for Self Assessment through the Trust Registration Service (TRS) rather than switching between reporting methods each year.
HMRC has also confirmed that it will stop processing legacy IHT100 forms after 31 August 2026, in line with its previously announced timetable. Tax professionals are encouraged to ensure estates are registered and reported using the appropriate processes before the deadline.
