Thanks heaps for the formula Adam.

The Excel version for the 2009-10 scales, in case anyone wants a quick copy-paste:
=IF(A1<=6000,0,IF(A1<=35000,0.15*(A1-6000),IF(A1<=80000,4350+(0.3*(A1-35000)),IF(A1<=180000,17850+(0.38*(A1-80000)),55850+(0.45*(A1-180000))))))

The scales are now different for 2010-11, making the Excel version:
=IF(A1<=6000,0,IF(A1<=37000,0.15*(A1-6000),IF(A1<=80000,4650+(0.3*(A1-37000)),IF(A1<=180000,17550+(0.37*(A1-80000)),54550+(0.45*(A1-180000))))))

This is great as a start. I am trying to do this by the month though, so if I predict the number of days I will work in a month and know my daily rate, I can put the correct tax aside to pay the man! Ideally, I would like to ‘average that out’, but I can’t seem to work out how to do this. Do you have any thoughts on this? – Doesn’t have to be perfect, just a good gut feel so I don’t get stung!

Cheers Muchly in advance

Thanks for the formula Adam.

Works great in Filemaker too (as expected):

Cut and paste into Filemaker, substitute ‘A1′ for the field containing your taxable income figure. Easy!

This is just a straight income tax calculation. It does not take into account any special tax office rules.

Glad to see it works OK in Excel with just a minor modification.

Hi Adam

I have compared you formula against the current TWC Calculator provided by the ATO.
When i select that I am entitled to Annual Leave it will provide me a different figure

Can you explain why that is?

Also in excel, a comma(,) is require instead of a semi-colon(;) as a separator between tests

Thanks
