There are several ways to do it, if just 1-2 years, normally will just lump up all the gross income into "Pendapatan Tahun Kebelakang ..."
But in your case ... 2009 - 2013 are 5 years to assess.
What to do:
1) Bring all documents, receipts, EA form, PCB, etc. to LHDN
2) Ask to speak to officer, get number.
3) They will give you 5x same BE or B form, and use pen to struck out the YA2013 and write each year.
4) So you will fill up year by year, i.e. do filing for 5 years.
5) So, the PCB whether is extra or not enough, is calculated yearly.
6) Then summarize up all, whether there is balance or need to pay.
7) This whole thing may take up several tries/trip to LHDN, or may email/call the office involved.
8) Keep all the forms and docs forever.
If they penalise you for late or no submission, ask for leniency or waive (talk nicely, you know govt dept).
If still need to pay, just pay. Nothing much can do, unless you go legal/court/challenge LHDN.
Remember, there are two things in life that can't avoid: death and tax.
Even though it is messy now, if you don't sort it out now, in future, it is even more messy. And you still need to sort it out.

you need to keep for 7 years only for the hard copies.
after slow talk usually can waive the penalty, but what needs to pay(under paid PCB), we still have to pay.
