"Hoffwn i ddiolch i Kathryn am ei holl gefnogaeth dros y 5 mlynedd diwethaf – drwy lawer o ddatblygiadau newydd ar gyfer treth yng Nghymru a chyfnod heriol y pandemig coronafeirws (COVID-19). Mae Kathryn wedi gwneud cyfraniad mawr wrth ein helpu i fod yr awdurdod treth modern yr oeddem am fod 5 mlynedd yn ôl.
“I’d like to thank Kathryn for all the support offered over the last 5 years – through many firsts for tax in Wales and the challenging times we found ourselves in during the coronavirus (COVID-19) pandemic. Kathryn has made a major contribution in helping us become the modern tax authority we aspired to be 5 years ago.
