Bydd yr adolygiad yn asesu’r opsiynau posibl a’u heffaith ar gyllid cyhoeddus a gwasanaethau lleol, yn ogystal ag ymchwilio i’r goblygiadau i’r rheini sy’n cael cymorth y Dreth Gyngor ar hyn o bryd, a thalwyr eraill y Dreth Gyngor. Bydd yn cynnwys dadansoddiad o’r cynlluniau sydd ar waith yn Lloegr ar hyn o bryd ac effeithiau diwygio lles i nodi opsiynau ymarferol a modelu eu heffaith debygol. Mae Grŵp Gorchwyl a Gorffen o swyddogion, cynrychiolwyr llywodraeth leol a staff Cyngor Ar Bopeth yn goruchwylio’r gwaith hwn.
The review will assess potential options and their impact on public finances and local services, as well as examining implications for those who currently receive Council Tax support  and other Council Tax payers.  It will include an analysis of the Schemes currently operating in England and the effects of welfare reform, to identify viable options and model their likely impact.  A Task and Finish Group of officials, Local Government representatives and  Citizens Advice Bureau  staff is overseeing this work.
