CH81170 – Penalties for Inaccuracies: Types of inaccuracy: Under- assessment by HMRC
You must check the date from which these rules apply for
the tax or duty you aredealing with. SeeCH81011for full details.
A penalty may be appropriate where tax has been
under-assessed because of the person’s (P’s) failure to
send us a return, see
CH81090. You must consider
- whether P knew or should have known about the under-assessment, and
- what steps (if any) it would have been reasonable for them to take to tell you about the under-assessment.
P must tell you if they think the assessment is too low. Reasonable steps to tell you about the under-assessment include
- phoning to discuss it
- writing, e-mailing or faxing an HMRC office to tell us the assessment is insufficient
- consulting an agent to enable them to inform us and ensuring HMRC are informed within the 30 day period
- sending us the completed return after the assessment has been issued.
P will not be liable to a penalty if they tell us that the
assessment is too low within 30 days of the date the assessment is
issued. P only has to tell us the assessment is too low. They do
not necessarily have to send us the outstanding return. You may
need to consider what other action is appropriate to obtain the
return.
A person who sends their return in on time will not receive
an assessment of estimated liability. They will have self-assessed,
or declared their tax liability, and so this penalty will not
apply.
This penalty could apply where, exceptionally, an IHT
account is not received within the appropriate time-limits and we
make a determination of the tax due.
