Professional Tax in West Bengal — what employers actually need to do

Professional Tax (P.Tax) in West Bengal is administered by the Directorate of Commercial Taxes under the West Bengal State Tax on Professions, Trades, Callings and Employments Act, 1979. It's small money per employee, but it has three moving parts that trip employers up if any one is neglected.

Here's the entire employer obligation in one page.

The two certificates

You need both of these — they cover different things:

• Enrolment Certificate (EC) — issued in Form II. This covers the entity itself (the company, the LLP, the partnership) for its own professional tax liability, paid annually.
• Registration Certificate (RC) — issued in Form I. This is what lets you deduct P.Tax from your salaried employees and deposit it with the government.

If you employ anyone in West Bengal and pay them a salary, you need the RC. If you're an entity carrying on trade or profession in West Bengal, you need the EC. Most employers need both.

The employee slab (deduct monthly)

For the financial year 2025–26, salary-based P.Tax slabs in West Bengal are broadly:

Monthly gross salary	P.Tax per month
Up to ₹10,000	Nil
₹10,001 – ₹15,000	₹110
₹15,001 – ₹25,000	₹130
₹25,001 – ₹40,000	₹150
Above ₹40,000	₹200

Deduct this in payroll, month on month. Deposit it with the state government against your RC, by the 21st of the following month.

(Slabs and thresholds are updated periodically. Always confirm the current notification before finalising a payroll run — that's part of what a retainer buys you.)

The entity slab (EC — annual)

The entity itself pays annually against the EC, in slabs based on turnover, capital, or other criteria depending on the class of assessee. Companies and LLPs typically pay ₹2,500 per annum. This is separate from what you deduct from employees.

The three deadlines to keep

• Monthly — deposit the employee deductions by the 21st of the following month.
• Annual return, Form III — file by 30 April for the previous financial year. This reconciles deductions with deposits.
• Annual entity payment (EC) — pay by 31 July for that financial year.

Miss any of these and you accumulate interest and penalty; miss them for long and you invite a notice.

The mistakes we see most

1. Having an EC but no RC — the entity is paying its own P.Tax but not deducting from employees. This looks fine until the first inspection.
2. Deducting on net instead of gross. The slab applies to gross monthly salary, not take-home.
3. Forgetting the annual return. The monthly deposits are done, but Form III never gets filed. It's the return that closes the year.
4. Directors treated as employees. Directors' remuneration attracts P.Tax under a slightly different treatment. Check before you assume.

What a clean file looks like

• Both certificates (EC and RC) held current.
• A monthly P.Tax register showing per-employee deduction.
• Monthly challan copies filed with the payroll pack.
• Form III filed and acknowledged, before 30 April, every year.

That's the whole thing. It's a small compliance in rupee terms — but a very visible one to any inspector or diligence lawyer walking through your file.
