(1)O ran asesiad ACC—
(a)caniateir ei wneud yn y ddau achos a bennir yn is-adrannau (2) a (3) yn unig, a
(b)ni chaniateir ei wneud yn yr amgylchiadau a bennir yn is-adran (4).
(2)Yr achos cyntaf yw pan fo’r sefyllfa a grybwyllir yn adran 54 neu 55 wedi ei pheri’n ddiofal neu’n fwriadol gan—
(a)y trethdalwr,
(b)person sy’n gweithredu ar ran y trethdalwr, neu
(c)person a oedd yn bartner yn yr un bartneriaeth â’r trethdalwr.
(3)Yr ail achos yw—
(a)pan fo hawl ACC i ddyroddi hysbysiad ymholiad i ffurflen dreth wedi dod i ben, neu pan fo wedi cwblhau ei ymholiadau i ffurflen dreth, a
(b)ar yr adeg y daeth yr hawl honno i ben neu y cwblhaodd yr ymholiadau hynny, na ellid bod wedi disgwyl yn rhesymol i ACC fod yn ymwybodol o’r sefyllfa a grybwyllir yn adran 54 neu 55 ar sail gwybodaeth a ddarparwyd iddo cyn yr adeg honno.
(4)Ni chaniateir gwneud asesiad ACC—
(a)os gellir priodoli’r sefyllfa a grybwyllir yn adran 54 neu 55 i gamgymeriad yn y ffurflen dreth o ran ar ba sail y dylid bod wedi cyfrifo’r rhwymedigaeth i’r dreth ddatganoledig, a
(b)os gwnaed y camgymeriad oherwydd bod y ffurflen dreth wedi ei dychwelyd ar y sail a oedd yn bodoli ar yr adeg y’i dychwelwyd, neu yn unol â’r arfer a oedd yn bodoli’n gyffredinol bryd hynny.
