From April 2023, local authorities have had the powers to introduce higher discretionary council tax premiums on second homes and long-term empty properties – up to 300%.
O ran y lefel uchaf y gall awdurdodau lleol ei defnyddio wrth bennu premiymau’r dreth gyngor ar ail gartrefi ac eiddo gwag hirdymor, bydd honno’n cynyddu i 300% - ac yn weithredol o fis Ebrill 2023.
