hm.. never ever. my transaction over the month when purchasing house > 100k. no one ever call me.

this including pay deposit, pay lawyer, pay contractor, etc. no one call me to explain the money as to date.

If the "work" is done outside of Malaysia, then yes. If you did the trade in Malaysia, even though the platform is overseas.. still considered you did the work in Malaysia.

Bank account transactions.

For instance, you receive RM3K from employer every month, you fill in the tax declaration form yearly. Out of a sudden, RM100K straight into the bank.
