GST on deposit

What happened to my accounting entries when I receive deposit for future tax invoices?

Scenario

1) Receive Deposit from Customer for 100.00 RM

2) Generate Invoice to Customer for 159.00 RM (Inclusive of tax)

3) Settle Invoice with Receipt

4) File Tax for both Receipt and Invoice

Jtxn during Creation of RCT

GLCode	Debit	Credit	Remarks
accReceivable		100	Debtors account
Bank	100		Money going in to bank / cashbook
gst_output		5.66	This GLCode has the amount of output tax collected (for all documents)
gst_output_suspended	5.66		This can be of any name, basically this is to see how much gst was collected for deposit and not invoiced out yet.


Jtxn during Creation of Invoice

GLCode	Debit	Credit	Remarks
accReceivable	159		Debtors account
generalSales		150	General Sales account
gst_output		9	This GLCode has the amount of output tax charged (for all documents)


Settling of Invoice with RCT

No JTXn created


Filing of both RCT and Invoice

GLCode	Debit	Credit	Remarks
gst_output	5.66		This amount was charged during the deposit, but reversed to avoid double tax upon settling the invoice.
gst_output_suspended		5.66	Upon filing, this account will be reduced to 0 since related tax invoice has already been created.

Refundable deposit do not have any GST!!
