SAM20010 - Assessments: stand-alone assessments: discovery assessment
A discovery assessment made under Section 29 TMA 1970 will normally be made when we have evidence听there鈥檚听been a loss of tax for听years听where no SA enquiry window exists.
HMRC powers听will make a discovery assessment听either
- After the听closure of an enquiry window
Or
- After an enquiry into that year鈥檚 SA return has been closed
Subject to the conditions in S29 TMA 1970, see EM3251+,听you may make a discovery assessment for a tax year to recover a loss of tax where
- There are profits which ought to have been assessed but haven鈥檛 been assessed
Or
- An assessment (including a self-assessment) has become insufficient
Or
- Any relief that has been given has become excessive
You may not make a discovery assessment if
- The return was made in accordance with the practice prevailing at that time, even if HMRC subsequently changes its practice in relation to a particular item and a resulting loss of tax arises
Or
- The enquiry window has closed or the enquiry has been completed, the information enabling the discovery was made available before that event and the behaviour behind the insufficiency was a mistake despite taking reasonable care
Detailed guidance concerning the discovery provisions can be found in the Enquiry Manual (see EM3201 onwards).
Discovery assessments are subject to appeal and postponement application. Guidance on handling appeals and postponements can be found at SAM10000 and SAM11000 respectively.
Where you are making a discovery assessment following a听discovery compliance check听and the case听is not linked to an open enquiry into a later return, you should create a record on Caseflow.
