How we keep this right
Every figure comes from an official LHDN source for a stated Year of Assessment, and never from memory. When the rules change, the guides are updated from the official documents. Older-year guides stay online, clearly labelled with their year.
A free, unofficial estimate to help you understand your tax — not a substitute for filing with LHDN.
