How long do HMRC have to enquire into a return that was filed on time?
They have 12 months from the ACTUAL date of filing to open an enquiry (i.e., if the return was
due on the 31 December 2022 but was filed on the 15 December 2022, then the deadline is
the 15 December 2023).
How long do HMRC have to enquire into a return that was filed late?
12 months after the quarter day following the filing date. The quarter days are the 31 January,
30 April, 31 July, 31 October.
What is a determination and when can HMRC make one?
A determination is an estimate of the tax due and is treated as the tax owed. HMRC must
make a determination within 3 years of the filing deadline. It is replaced by the actual tax
liability on submission.
