I'm in the middle of filing income tax for Sole Proprietor Year 2012.
There are few invoices in which I'm unable to recover the payment.
May I know how should I file the losses for those few invoices?

I would like to ask about Tax Submission for Form B.
After calculation, the amount taxable exceed the total amount stated on CP500 & I proceed to pay the balance via Maybank2U. May I know is the procedure correct?

In summary, what I did:
i) Paid CP500
ii) Submit Form B via Income Tax submission online.
iii) Paid the balance to LHDN via Maybank2U.

Is it all? Is there's something that I missed out like additional form that need to be filled in?
