About this tool
Half-yearly professional tax for Tamil Nadu employees using the Greater Chennai Corporation income slabs.
The Professional Tax Calculator Tamil Nadu converts a Tamil Nadu salary into the half-yearly professional tax the local body charges, using the Greater Chennai Corporation slab schedule made under the Tamil Nadu Municipal Laws (Second Amendment) Act 1998. Tamil Nadu is unusual in assessing professional tax on six months of income rather than on monthly salary, so the tool multiplies a monthly figure by six before applying the bands. It suits payroll staff and employees reconciling a twice-a-year deduction on a Chennai or Coimbatore payslip.

Type the figure into "Income (INR)" and set "The figure above is" to Monthly salary or Half-yearly income; a monthly salary is multiplied by the six months in a Tamil Nadu half-year.
The half-yearly figure is matched to the Greater Chennai Corporation schedule — nil up to Rs 21,000, then Rs 135, Rs 315, Rs 690, Rs 1,025, and Rs 1,250 above Rs 75,000 — and the matching row is highlighted in the "Half-yearly slab table".
"Professional tax per half-year" shows the amount with the Applicable slab, the full-year total against the Rs 2,500 Tamil Nadu maximum, and the 1 April to 30 September and 1 October to 31 March instalments with their pay-by dates. "Copy result" copies it.
Assesses six months of income the way the state actually charges it.
Accepts a monthly salary or a half-yearly income figure.
Splits the year into the April-September and October-March halves.
It is charged on half-yearly income, not monthly salary. Under the Greater Chennai Corporation schedule the tax is nil up to Rs 21,000 half-yearly, Rs 135 up to Rs 30,000, Rs 315 up to Rs 45,000, Rs 690 up to Rs 60,000, Rs 1,025 up to Rs 75,000 and Rs 1,250 above that.
The state runs two half-years, 1 April to 30 September and 1 October to 31 March, with the tax for each half payable by the end of that period. Employers usually deduct it in one instalment per half-year rather than monthly.
Rs 2,500 for the year, being Rs 1,250 in each half-year for anyone with half-yearly income above Rs 75,000. That figure is the ceiling Article 276(2) of the Constitution places on professional tax anywhere in India.
Professional tax is a local-body levy in Tamil Nadu, so a municipality or town panchayat can notify its own amounts, although most closely follow the Greater Chennai Corporation schedule. Check your local body's notification if the deduction on your payslip differs.
