GST on advance Receipts -reg

Hi ,

There is a Business Requirement in Malaysian GST where the customer should issue Tax Invoice while receiving Advance and GST to be charged on Advance.   Similarly when final Invoice is raised, GST should be charged only on the Net amount ( Invoice Amt - Less Advance ) .  Let us explain by an example.

Total Order Value - 100000 MYR;

Advance 20%  - Invoice for advance should be as shown below;

Total Advance - 100000 *20%         ---- 20000

GST @ 6%           20000*6%             ---     1200

                                                                --------------

Total                                                              21200

                                                                 --------------

Now the supply is effected and the customer is to raise Invoice as shown below;

Total   Value                                                      100000

Less Advance                                                      20000

                                                                  -------------------

Net                                                                         80000

GST @ 6%                                                              4800

                                                                   ---------------------

                                   Total                                    84800
