Tax is wrong on products when discounts are used

Hi,

This is the first time I have played with the discounting features of ZC and I have noticed on the checkout that when I use ZC built-in discounts the TAX is wrong..........

eg: Product with a discount applied (full price £2.25, discounted to £1.65 with 7521 units in the cart)

Sub-Total:£12,409.65
TAX@ 20%: £2,481.93
Total:£14,891.58

this is wrong, it should be £14,890.80, making the TAX out by 79p

clean install, no mods...
bit of a bugger as I was considering using the discount features, but can't :(
Now, I'd happily short change the TAX man of money, but sadly its illegal :(:(

any ideas?

or i cannot do maths..???

but I had one test order of about £2000 come out the 25 quid tax, hence me noticing this............ :frusty::wacko:

Hmmm,

12409.65 * 20/100 = 2481.93

12409.65 + 2481.93 = 14891.58

Not sure what the prob is ?

I cannot recreate this again, I was clearly wrong or confused at the time. Thank you.
