The figures are the Finance Act’s own. Every rate, threshold and exemption on this page was taken out of the Income Tax Department’s own text of the Act that charged the year — the charging section and the First Schedule — and the records we read are linked under Sources on each year’s page. The writing around the figures is ours: the arrangement, the headings, the comparison with the year before and every sentence of explanation. Those are not the Act.
These tables are for orientation. The Act governs. A rate table is a finding aid, not the law. The Act, its First Schedule and the provisos in it decide what is payable, and a table cannot carry the provisos. If you are about to rely on a figure here — in a return, in a computation, in a reply to a notice — open the source linked on the year’s page and read the figure in the Act for yourself. Where a record did not reach a rate, this library says so rather than filling the gap.
