Tamil Nadu Professional Tax Overview
Tamil Nadu levies Professional Tax under the Tamil Nadu Tax on Professions, Trades, Callings and Employments Act, 1992. Unlike most states that collect PT monthly, Tamil Nadu follows a half-yearly collection system with two periods: April–September and October–March.

FAQs
Why does Tamil Nadu charge PT half-yearly?
Tamil Nadu’s PT Act specifies half-yearly assessment periods. This means the tax is calculated on 6 months of income rather than monthly, which affects how slabs are applied.
How do employers deduct TN PT from monthly salary?
Most employers divide the half-yearly PT by 6 and deduct it monthly. For example, if the half-yearly PT is ₹1,250, the monthly deduction would be approximately ₹208.
