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 — such as the Greater Chennai Corporation (GCC). It's 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 or municipality.
A worked example
If your average half-yearly income is ₹50,000, you fall in the ₹45,001–60,000 slab, so PT = ₹690 per half-year, about ₹1,380 a year.
When it is paid, and by whom
- First half-year (April–September): by 30 September.
- Second half-year (October–March): by 31 March.
- Salaried: the employer deducts PT from your salary and pays it to the corporation.
- Self-employed / traders: register with the local body and pay directly.
Is professional tax tax-deductible?
Yes — PT paid is deductible from your salary income under the Income-tax Act, so it reduces your taxable salary. It's a small saving, but it's automatic once the deduction is claimed.
What if you don't pay?
Non-payment or late payment of professional tax can attract interest and penalties from the local body, and for businesses it can complicate registrations and licences. For salaried employees this rarely happens (the employer handles it), but self-employed people and traders should register and pay on time to avoid the add-ons.
