Its okay i have the answer
GST Payable is a internal amount calculated by the system based on info we have input
such as Sales and tax collected therin
It also internally calculates from the amounts we paid from our bills for purchases we paid for...etc
it is a net amount of GST PAYABLE is based on the difference of the two of them
To get a better perspective separate them download the GST Payable to EXcel Spreadsheet and separate the pluses and minuses to see the real effect on this G/L
Try it it really works well for those who have questions on this very important tax tool
Thx,
