Mae’r gwaith o weinyddu CTIC nawr wedi symud ymlaen at gam ‘busnes fel arfer’ sy’n canolbwyntio ar gynnal a diweddaru systemau, a chodi ymwybyddiaeth ynglŷn â CTIC. Fel y nodir yn y Cytundeb Lefel Gwasanaeth, sefydlwyd strwythur llywodraethu ffurfiol i sicrhau cysondeb o ran ansawdd y gwasanaeth i drethdalwyr Cymru, ac i ganiatáu i CThEM a Llywodraeth Cymru gyflawni eu cyfrifoldebau mewn perthynas â gweithredu CTIC.
The administration of WRIT has now moved into a business as usual phase focussing on maintaining and updating systems and improving awareness of WRIT. As set out in the Service Level Agreement (SLA), a formal governance structure is in place to ensure a consistent quality of service to Welsh taxpayers and allow HMRC and the Welsh Government to meet their respective responsibilities in respect of operating WRIT.
