- To get GST part of GST inclusive amount you need divide GST inclusive amount by 108 and multiply by 8

$216 is GST inclusive value

($216 / 108) * 8 = $16 GST value

- To get GST exclusive amount while knowing GST inclusive value you need to multiply GST inclusive price by 100 ant then divide result by 108

$216 is GST inclusive value

$216*100=$21600

Hello there

I’m having trouble submitting an electronic invoice for Vendors @ Gov.

A school office ordered an item for $ 1.60 including GST,

When I create an electronic invoice, the amount excluding 7% GST should be $ 1.495,

GST becomes $ 0.11, so the total GST is $ 1.61,

I have changed the Goods and Services Tax (GST) to 0.10 to get a total Goods and Services Tax of $ 1.60,

However, an error occurred while submitting the electronic invoice.

A message always appears:

Goods and services tax excluding GST shall be 7% of the total amount and the difference accepted is +/- 0.25% or $ 0.50, whichever is lower.

Please help solve this problem, thanks.

Item $ 1.60/- including GST

(1.60/107)*7 = $ 0.10 is GST value

$1.60 – $ 0.10 = $ 1.50/- is exclusive GST
