Manylion

Mae’r ‘Cod Ymarfer’ (COP26) hwn yn rhoi gwybodaeth fanwl am ordaliadau credydau treth, gan gynnwys:

  • pam mae gordaliadau’n gallu digwydd
  • sut i ad-dalu gordaliad (a phryd nad oes angen i chi wneud hynny)
  • herio adennill gordaliad
  • yr hyn sy’n digwydd i’ch gordaliad os byddwch yn gofyn am i’ch dyfarniad credydau treth gael ei ailystyried

Mae hefyd yn cwmpasu’r hyn y dylech chi a’r Swyddfa Credydau Treth ei wneud er mwyn helpu i gael eich credydau treth yn gywir ac i osgoi gordaliad.

Nid yw’n berthnasol i Daliadau Costau Byw.
