GST not calculating 10%

i have a tax class that is setup for Australian GST = 10% on all products.
For an $18 item, GST on the store is being calculated at $1.64 where it should be $1.80

Under my Products/Categories it is also wrong at
NET - $16.3636
GROSS - $18.00

Anyone know what im missing ?

Actually I don't know what you are seeing... these figures are perfectly accurate.

18/11 = 1.63636 ($1.64) +Net @ $16.3636 = $18.00 GROSS

To obtain what you are expecting, the NET price needs to be $18.00 and the GROSS price will be $19.80 ($18 + $1.80)

ps. Don't charge GST unless you are registered to do so, and don't register to do so unless your turnover is over $75k p/a (else you are nominating yourself to become an unpaid tax collector)

Ah thankyou Rod.
Now you explain it, i see the way GST is calculated.
Im not good with calculating numbers, thats why im not an accountant!

Thanks
