Ok here is what i have i have created a payroll. now i need to add this:

if pay is $0 - $95 deduct $0 plus 0c per dollar over 0
if pay is $96-$345 deduct $0 plus 20c per dollar over 96
if pay is $346-$480 deduct $63 plus 25c per dollar over 346
if pay is $481-$672 deduct $96 plus 40c per dollar over 481
if pay is $673-$961 deduct $183 plus 47c per dollar over 673
if pay is $962+ deduct $308 plus 48c per dollar over 962

And make it automatically deduct from the Gross Income.
I have tried this
=IF(C4300,C4<400,(C4-43)*0.36,IF(C4401,C4<500,(C4-60)*0.45,IF(C4501,<600,(C4-200)*0.60)))

(numbers were just to try out)
and it didnt work.
How would i go about creating such a formula? or is there a different way of
handling it?
