O ran y lefel uchaf y gall awdurdodau lleol ei defnyddio wrth bennu premiymau’r dreth gyngor ar ail gartrefi ac eiddo gwag hirdymor, byddaf yn cyflwyno deddfwriaeth newydd i gynyddu hon i 300%, gan ddod yn weithredol o 1 Ebrill 2023.  Mae’r gallu i godi premiymau treth gyngor ychwanegol wedi’i groesawu fel dull y gall awdurdodau lleol ei ddefnyddio i liniaru'r effeithiau negyddol y gall ail gartrefi ac eiddo gwag hirdymor eu cael.  Er nad yw llawer o'r cyfleoedd i fynd i'r afael â materion tai drwy bremiymau wedi'u gwireddu'n llawn eto, bydd cynyddu'r lefel uchaf yn galluogi awdurdodau lleol i benderfynu ar lefel sy'n briodol i’w hamgylchiadau lleol unigol pan fo'r amser yn iawn iddynt.   Gall awdurdodau bennu'r premiwm ar unrhyw lefel hyd at yr uchafswm a gallant gymhwyso premiymau gwahanol i ail gartrefi ac anheddau gwag hirdymor.  Fel yn awr, mater i awdurdodau unigol fydd penderfynu a ddylid cymhwyso premiwm ac ar ba lefel i'w gymhwyso.
In relation to the maximum level at which local authorities can set council tax premiums on second homes and long-term empty properties, I will introduce new legislation to increase this to 300%, effective from 1 April 2023.  The ability to charge additional council tax premiums has been welcomed as a mechanism for local authorities to mitigate the negative impacts that second homes and long-term empty properties can have. While many of the opportunities for addressing housing issues through premiums have not yet been fully realised, increasing the maximum level will enable local authorities to decide a level appropriate for their individual local circumstances when the time is right for them. Authorities can set the premium at any level up to the maximum and can apply different premiums to second homes and long-term empty dwellings. As now, it will be for individual authorities to decide whether to apply a premium and at what level to apply it.
