Cell A1 has a mothly salary figure before tax. Cell A2 should have the payable tax calculated that should be paid from that salary using the following rules:
Income per annum up to 14000 taxed at 10,5%
Income per annum between 14001 to 48000 17,5%
Income per annum between 48001 to 70000 30%
Income above 70001 taxed at 33%
The above percentages don't apply for the whole salary, say, if one is in the highest band, but instead, the first 14k are taxed at 10,5%, and the next 33999 are taxed at 17,5% etc until the entire salary of cell A1 is allocated across all tax bands.

Thank you guys!
