GST - Withdrawls calculating at 12.5% instead of 15%

[BBQSauce]

Hi, one company that withdrawls from my account is being calculated under GST at 12.5%, how do I make 12.5% not an option and how to I make the GST portion only 15%?

Hi there @BBQSauce

Check that the GST default code in the expense account you coded the withdrawal to the correct S15 code.

Also check the supplier card (if you use one) that their GST code is not over riding to S code.

To be doubly sure - go to Lists - GST codes and change the S code to 15% rather than 12.5%
