TN Professional Tax Calculator
How Tamil Nadu professional tax is calculated
Professional tax (PT) is a small tax that salaried employees, professionals and traders in Tamil Nadu pay to their local body — for example the Greater Chennai Corporation (GCC). It is charged on your average half-yearly income using a slab system and paid twice a year. The calculator above gives the PT for your slab.
Greater Chennai Corporation slabs
| Average half-yearly income | PT (per half year) |
|---|---|
| Up to ₹21,000 | Nil |
| ₹21,001 to ₹30,000 | ₹135 |
| ₹30,001 to ₹45,000 | ₹315 |
| ₹45,001 to ₹60,000 | ₹690 |
| ₹60,001 to ₹75,000 | ₹1,025 |
| Above ₹75,000 | ₹1,250 |
Slabs vary slightly between local bodies and are revised periodically — confirm with your corporation/municipality.
