Pan gyhoeddodd Llywodraeth y DU y newidiadau, fe ddywedodd hefyd y byddai’n trosglwyddo cyllid i Gyllideb Cymru i gyd-fynd â’r cyfrifoldeb hwn, ond y byddai’r cyllid yn gostwng 10% o gymharu â’r cyllid ar gyfer budd-dal y dreth gyngor.
When the UK government announced the changes, it also indicated that it would make a transfer of funding to the Welsh Budget to accompany this new responsibility but that the funding provision would be cut by 10% compared to the funding for council tax benefit.
