• To calculate Singaporean GST at 9% rate is very easy: just multiple your GST exclusive amount by 0.09.

\$300 is GST exclusive value

\$300 * 0.09 = \$27 GST amount

• To get GST inclusive amount multiply GST exclusive value by 1.09

\$300 is GST exclusive value

\$300 * 1.09 = \$327 GST inclusive amount

• To get GST part of GST inclusive amount you need divide GST inclusive amount by 109 and multiply by 9

\$218 is GST inclusive value

(\$218 / 109) * 9 = \$18 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 109

\$218 is GST inclusive value

\$218*100=\$21800

\$21800/ 109 = \$200

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.

Item \$ 1.60/- including GST

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

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