Tamil Nadu Professional Tax: Slabs & Half-Yearly Compliance Guide
In Tamil Nadu, Professional Tax is governed by the Tamil Nadu Municipal Laws (Second Amendment) Act, 1998 and the respective City Municipal Corporation Acts (including the Chennai City Municipal Corporation Act, 1919).
Unlike most Indian states where Professional Tax is collected on a monthly basis by the State Commercial Taxes Department, Tamil Nadu administers Professional Tax through Urban Local Bodies (Municipal Corporations, Municipalities, and Town Panchayats) on a half-yearly (semi-annual) schedule.
📊 Half-Yearly Income Slabs & Deduction Rates (Chennai & Tamil Nadu Municipalities)
Deductions are calculated based on average half-yearly gross earnings (April–September and October–March):
| Half-Yearly Gross Salary / Income Range | Half-Yearly Tax Deduction (₹) | Approximate Monthly Equivalent (₹) | Annual Professional Tax (₹) |
|---|---|---|---|
| Up to ₹21,000 | NIL | NIL | ₹0 |
| ₹21,001 to ₹30,000 | ₹135 | ₹22.50 / month | ₹270 |
| ₹30,001 to ₹45,000 | ₹315 | ₹52.50 / month | ₹630 |
| ₹45,001 to ₹60,000 | ₹690 | ₹115.00 / month | ₹1,380 |
| ₹60,001 to ₹75,000 | ₹1,025 | ₹170.83 / month | ₹2,050 |
| ₹75,001 and Above | ₹1,250 | ₹208.33 / month | ₹2,500 (Full statutory cap) |
Because deductions are legally half-yearly, corporate employers and HR payroll teams typically adopt one of two practices:
- Monthly Pro-Rata Accrual: Deduct ₹208.33 (or ₹208/₹209) each month from salaried staff and remit the accumulated ₹1,250 at the end of each half-year.
- Lump-Sum Half-Yearly Deduction: Deduct the entire ₹1,250 directly from the payroll in the designated due months (September and February/March).
