Tax Collection and Management (Wales) Act 2016 section 54

Assessment where loss of tax

Section 54 sets out the circumstances in which the Welsh Revenue Authority (WRA) may raise an assessment to recover devolved tax that has been lost or under-collected.

• WRA can raise an assessment if a devolved tax that should have been charged on a person was never assessed in the first place.
• WRA can raise a further assessment if an existing assessment of devolved tax turns out to be, or has become, too low.
• WRA can raise an assessment if tax relief has been claimed or granted that is, or has become, excessive.
• In any of these cases, WRA may assess whatever amount it considers necessary to make good the loss of tax.
