Im going to hazzard a guess you have fallen victim to a common misunderstanding.
Is 100 your total/gross price?
Is your price list set to be inclusive of tax?
If the ticket exc tax was 100 the tax would be 5 (5% of 100) making total/gross price 105
If the total including tax was 100 it would not be 5 tax, as tax would be 5% of the exc price;
For example on that basis net would be 95. 5% of 95 is 4.75 so total is 99.75
To get a total gross price of 100 with 5% the net price would be 100/1.05 = 95.23 and depending on your rounding 95.2 so 4.80 tax.
If I have guessed right you just saved 0.20 on tax and think how that adds up over a year
Yeah, sorry, I was thinking about that too. But I guess here I need to do tax including and than it’s what you said, it’s not going to be 5. Stupid me, but it’s what you get when staring at SambaPOS for a day and guessing how to implement things. If there would be a step-by-step guide for V5 it would help a lot. I was caught I think by the fact that in Taiwan there are no decimals, it’s all rounded to 1 NT$, we don’t have half or quarters, 10 cents or anything of that kind. Just when it comes to VAT calculation you get decimals in the result, and then I better round at the end of the two month period, not for every ticket I’ll print.
