You must check the date from which these rules apply for

Where a person (P) has to rely upon information provided by
another person (T) to prepare their return or other document, we
expect P to take reasonable care, see
CH81120, to make sure that the
information they are given is accurate and complete.
If P’s document is inaccurate and the inaccuracy
relates to information supplied (or not supplied) by T, you will
need to consider whether P has taken reasonable care to check the
information provided (or not provided) by T. You will need to take
into account
Within this context you will need to consider
Where P takes reasonable care but the return or document is still inaccurate, they will not be liable to a penalty for that inaccuracy. The other person, T, may be charged a penalty if they deliberately, see CH81150 and CH81160,
with the intention of P submitting an inaccurate document.
Further guidance on this penalty is at
CH81165.
Where T is an agent, see
CH84545.
