Your question is very broad. I assume you are asking from personal tax perspective where you only have employment income and no other passive income such as rental and dividend. If that the case, you can only reduce your tax by maximise your personal relief. In order to maximise it, i will suggest that you have a quick look at the list of the personal relief available for us. But generally, most of the ppl will claim book and magazine, broadband, life insurance and epf, medical insurance and of course self relief. Keep all the relevant receipts for those available relief claims.

There's no way you put the balance somewhere. Just ignore it.

EPF+Life Insurance = max up to RM 6k
