Fel y gwyddai’r aelodau, rhoddodd Deddf Cymru 2014 y pŵer i’r Senedd i sefydlu Cyfraddau Treth Incwm Cymru (CTIC). Fel y cytunwyd yn fframwaith gyllidol Llywodraeth Cymru ym mis Rhagfyr 2016, cyflwynwyd CTIC ar 6 Ebrill 2019.
As members will be aware, the Wales Act 2014 gave the Senedd the power to set Welsh Rates of Income Tax (WRIT). As agreed in the Welsh Government’s fiscal framework in December 2016, WRIT was introduced on 6 April 2019.
