The Welsh Revenue Authority does not produce a single quantified estimate of a tax gap for devolved taxes because there is no robust population-wide benchmark of the total theoretical liability.

The WRA publishes reports on its performance, including operational outcomes from compliance activity such as tax recovered from errors, revenue protected by stopping invalid repayments and claims, and targeted interventions on emerging risks.

Overall, published figures show that the system is working well overall and that the WRA’s tax compliance approach (Our Approach) is supporting high levels of compliance. (Saesneg yn unig)
