 Question from CAROL: THE INVOICE TOTAL IS 2731.90 BUT IT DOES NOT SHOW WHAT THE NET AMOUNT IS THAT THE STATED GST OF 121.90 IS. HOW DO I CALCULATE THE NET AMOUNT THAT THIS GST AMOUNT REFERS TO?

Link didn't help, I have an invoice with the total of $2731.90, it is noted that the GST is$121.90. I need to know what amount of 2731.90 has the 5% GST included, and the amount that has no tax. Thanks

Carol

Hi Carol,

Now I see. You have an invoice, part of which is taxable and part is not. The 5% GST on the taxable amount is $121.90 so the person who sent the invoice calculated (taxable amount) × 0.05 =$121.90.

Hence you can calculate (taxable amount) = $121.90/0.05 =$2438.00. Thus the invoice broken down is

Taxable Amount $2438.00$121.90 $2559.90$172.00 \$2731.90
