| Aspect | Professional Tax | Income Tax |
|---|---|---|
| Levied By | State Government (Chennai Corporation) | Central Government |
| Maximum Rate | ₹1,000/month | 30% + surcharge |
| Exemption Limit | ₹15,000/month | ₹2.5 lakhs/year |
| Deduction | Allowed under Section 16(iii) of IT Act | N/A |

Can I claim refund if excess professional tax was deducted?
Yes, you can claim refund for excess professional tax deducted through these steps:
- Obtain Form 16A from your employer showing tax deducted
- File application with Chennai Corporation’s Assessment Department
- Submit supporting documents (salary slips, bank statements)
- Provide proof of current correct deductions
- Refund is typically processed within 45-60 days
Note: Refunds are only possible for current financial year. No carry-forward to next year is allowed.
Are there any exemptions from professional tax in Chennai?

How does professional tax affect my income tax calculation?
Professional tax impacts your income tax in two ways:

- Form 16 Reporting: Your employer must report professional tax deductions in Part B of Form 16. This amount is automatically considered when calculating your taxable income.
Example: If you paid ₹8,000 as professional tax in a year, your taxable income reduces by ₹8,000, potentially saving you up to ₹2,400 in income tax (at 30% slab).
