How do I easily find how much is subject to GST if only a portion of the receipt is charged GST?
Hi, I find I often have to "reverse calculate" to get my GST amount correct. For example my receipt is a subtotal of $134.43 but the GST charged is $2.44. For my entry the amounts are inclusive of tax, I use 2 lines, the first line is the category (tools, supplies, fuel or whatever) the sales tax is GST, and I fiddle with the amount to make sure my GST portion at the bottom matches my receipt, then I put the difference on the second line with the same category but tax at zero rated.
It is very fiddly trying to get the amount correct to show the right tax amount. Is there any easier way to have the GST at $2.44 and calculate what that amount is calculated on?
