Tax Collection and Management (Wales) Act 2016 section 44

Scope of enquiry

Section 44 defines what the Welsh Revenue Authority (WRA) can examine when it opens an enquiry into a tax return, and how the scope is limited when an enquiry follows a taxpayer amendment made after a previous enquiry has already been completed.

• An enquiry can cover anything in the tax return, or anything that should have been in it, relating to whether the person is chargeable to the relevant devolved tax and, if so, the amount chargeable.
• The enquiry equally extends to whether the person is entitled to any tax credit claimed in the return, and to the amount of that tax credit.
• Where a taxpayer amends a return after an earlier enquiry into that return has been completed, a fresh enquiry can only look at matters to which the amendment relates and matters affected by it.
• The scope limitation for post-amendment enquiries prevents the WRA from reopening issues that were already settled in the earlier enquiry, unless they are connected to the new amendment.
