As our statistics are derived from live data systems, our statistics for both Land Transaction Tax and Landfill Disposals Tax have planned revisions.
Gan fod ein hystadegau’n seiliedig ar systemau data byw, mae adolygiadau wedi’u cynllunio yn cael eu cynnal mewn perthynas â'r Dreth Trafodiadau Tir a'r Dreth Gwarediadau Tirlenwi.
