Fel llywodraeth, fe wnaethom y dewis cywir i fod yn ofalus ar y cychwyn wrth fynd ati i ddiwygio trethi – a hynny er mwyn atal, hyd y bo modd, y risg o broblemau wrth i’r system newydd ymwreiddio. Mae cyflwyno cyfraddau treth incwm Cymru yn ddatblygiad arwyddocaol yn hanes datganoli Cymreig, ac mae Llywodraeth Cymru’n benderfynol y dylai trethdalwyr Cymru gael gwasanaeth sy’n ddibynadwy ac yn effeithiol. Mae’n siom, yn yr achos hwn, fod anhwylustod wedi’i achosi i rai o drethdalwyr Cymru.
As a government, we rightly chose to be cautious in our approach to tax reform at the beginning, to prevent as far as possible the risk of problems while the new system is bedding in. WRIT is a significant development in Welsh devolution, and the Welsh Government is determined that Welsh taxpayers are provided with a service which is both reliable and efficient. It is disappointing that in this case some Welsh taxpayers have been inconvenienced.
