Gan gydnabod y dylid ystyried diwygiadau o’r fath yn ofalus, mae Llywodraeth Cymru eisoes wedi cymryd camau pwysig i ddatblygu system treth gyngor decach yng Nghymru. Gan weithio’n agos gyda chynghorau lleol a Chymdeithas Llywodraeth Leol Cymru, cyflwynwyd deddfwriaeth newydd yn 2019 i gael gwared ar y gosb o ddedfryd o garchar am beidio â thalu'r dreth gyngor ac mae system rheoli dyledion sy’n canolbwyntio’n fwy ar y dinesydd wedi’i datblygu. Mae Llywodraeth Cymru hefyd wedi gweithio gyda MoneySavingExpert.com i wella mynediad at ostyngiadau ar gyfer pobl â nam meddyliol difrifol ac wedi annog aelwydydd incwm isel i fanteisio ar ei Chynllun Gostyngiadau’r Dreth Gyngor, gan leddfu rhai o effeithiau Credyd Cynhwysol. Mae pobl ifanc sy’n gadael gofal hefyd wedi’u heithrio rhag y dreth gyngor.
Recognising that such reforms should be considered carefully, the Welsh Government has already taken important steps to develop a fairer council tax system in Wales. Working closely with local councils and the Welsh Local Government Association (WLGA), new legislation to remove imprisonment for non-payment of council tax was introduced in 2019 and a more citizen-focused system for managing debt has been developed. The Welsh Government has also worked with MoneySavingExpert.com to improve access to discounts for people with severe mental impairments and encouraged low-income households to take up its Council Tax Reduction Scheme, mitigating some of the effects of Universal Credit. Young care leavers have also been exempted from council tax.
