Professional Tax
Professional Tax in Tamil Nadu — Half-Yearly Slabs Explained
Tamil Nadu bills professional tax half-yearly, not monthly — Greater Chennai Corporation slabs run ₹180 to ₹1,250 per half-year (₹2,500/year at the top), deducted in August and January.
Tamil Nadu is a half-yearly state, not a monthly one — professional tax is assessed on average monthly income but actually deducted and deposited twice a year, in August (for April–September) and January (for October–March), rather than every payslip.
It's also locally administered: rates below are the Greater Chennai Corporation's current slabs, which are the most commonly cited reference, but other municipal corporations and panchayats in Tamil Nadu set their own rates within similar income bands — confirm with the local body your business or employment falls under.
The figure this calculator shows is a monthly equivalent (the half-yearly amount ÷ 6) purely for comparability with other states — what actually happens on a Tamil Nadu payslip is two lump-sum deductions a year, not a small monthly one.
Worked example
A standard month works out to ₹155.00. A ₹50,000-a-month salary falls in the ₹45,001–₹60,000 band: ₹930 deducted once in August and again in January — ₹1,860 for the year, under Greater Chennai Corporation's current slabs.
Frequently asked questions
Why is this shown as a monthly figure if it's actually paid twice a year?
For comparability with states that deduct monthly. On an actual Tamil Nadu payslip, you won't see a small deduction every month — you'll see a larger one in August and another in January, each half of the annual figure.
Do all cities and panchayats in Tamil Nadu charge the same rate?
No — Greater Chennai Corporation's slabs (shown here) are the most commonly referenced, but other corporations and panchayats set their own rates within broadly similar income bands. Confirm with the specific local body.
Is Tamil Nadu also capped at ₹2,500 a year like other states?
Yes — the top slab (₹1,250 per half-year) works out to exactly ₹2,500 a year, the constitutional maximum under Article 276(2).
