Daw'r angen i ddechrau'r broses hon nawr o ganlyniad i Ddeddf Deddfau Trethi Cymru etc. (Pŵer i Addasu) 2022, a basiwyd yn ystod tymor y Senedd hon ac a ddaeth i rym ar 9 Medi 2022.
The need to begin this process now comes as a consequence of the Welsh Tax Acts etc. (Power to Modify) Act 2022, passed during this Senedd term and which came into force on 9 September 2022.
