Professional Tax Registration for Employers: State Slabs, Monthly Filing and What It Costs You

Professional Tax for Employers: Registration, State Slabs and Monthly Filing

If you run payroll in West Bengal, September 2026 was the last month under the old slabs. From 1 October 2026 the nil limit doubled to ₹20,000 — staff who paid ₹110 or ₹130 till September now pay nothing. A payroll run still on the old ₹10,000 threshold is deducting tax it has no business deducting. Professional tax is not one tax. It is a dozen-odd state taxes sharing a name — and the employer, not the employee, carries the compliance for every one of them.

The short answer: Professional tax is a state-level tax on salaries, professions and trades in India, capped at ₹2,500 per employee per year under Article 276 of the Constitution. Employers must register (PTRC), deduct it from salaries every month, deposit it with the state government, and file periodic returns. Slabs, due dates and portals differ in every state.

What professional tax actually is — and why payroll software keeps getting it wrong

Article 276 lets states tax "professions, trades, callings and employments" and caps it at ₹2,500 per person per year. Everything else — slabs, rates, due dates, portals, return formats — is each state's own invention. That is why payroll software configured for one state quietly misfires in another.

Think of your company as the electricity distributor. The state sets the tariff — that is the slab. You collect it on each consumer's bill — that is the payslip deduction — and remit it by a fixed date. Miss the remittance and the penalty lands on you, the distributor, not the consumer. That is professional tax: the employee's tax, the employer's headache. One consolation for staff: PT deducted from salary reduces taxable salary income.

First check: does your state even levy it?

About 17 states levy professional tax — Maharashtra, Karnataka, West Bengal, Tamil Nadu, Telangana, Andhra Pradesh, Gujarat, Madhya Pradesh, Kerala, Bihar and Odisha. Delhi, Uttar Pradesh, Haryana, Punjab and Rajasthan do not levy it at all.

A Delhi company opening its first Mumbai office enters a monthly routine it never had at headquarters. I have seen the branch run payroll for six months before anyone asks where the PT line is. Check first. Two minutes now saves a penalty notice later.

PTRC vs PTEC — the two registrations employers confuse

Most employers need both. PTRC (Professional Tax Registration Certificate) authorises you to deduct PT from salaries and deposit it. PTEC (Professional Tax Enrolment Certificate) enrols the business itself — your company is itself a "person" carrying on a trade, so it pays PT on itself, separately from staff deductions.

In Maharashtra both live on the MahaGST portal and registration is quick and online; Karnataka and West Bengal run their own portals. Portals differ; the principle does not: deduct as employer (PTRC), enrol as entity (PTEC).

What are the professional tax slabs in 2026?

Most states compute slabs on monthly salary or wages:

*West Bengal's new slabs apply from 1 October 2026 (Finance Department notification 1407-F.T. dated 18 August 2026, under the West Bengal Finance Act, 2026). September 2026 salaries used the old slabs — nil to ₹10,000, then ₹110/₹130/₹150/₹200 above ₹40,000. If your payroll vendor has not updated the master, chase them this week.

Tamil Nadu does it differently — half-yearly, not monthly. The April–September half was due by 30 September 2026; the October–March half falls due at the end of March, with slabs from nil to ₹1,250 per half-year at the top. Different rhythm, same discipline.

How do I file professional tax every month?

Four steps, in order. 1. Deduct — compute PT per the slab, show it as a payslip line. 2. Deposit — pay it through the state portal by the due date. For September 2026 salaries, payable this month: Maharashtra and Gujarat the 15th, Karnataka the 20th, West Bengal the 21st, AP/Telangana/MP the 10th — indicative, confirm on your state portal. 3. File the return — depositing is not filing. Maharashtra: monthly if annual liability is ₹50,000+, annual if smaller. Karnataka: annual return. West Bengal: monthly. 4. Keep the challans — the first documents any inspector asks for. One folder per financial year, per state.

PT slots into the same monthly calendar as PF and ESI — our payroll compliance guide shows how the three sit together, and the compliance fee calculator puts real numbers on the monthly load.

How much does professional tax registration cost?

Less than you fear. Government fees are nominal — usually a few hundred rupees, and online registration is free in several states. The expensive part is the monthly discipline. Most employers who come to us for professional tax registration are buying the certainty that the routine runs without them. And if you have not taken Shops and Establishment registration yet, do both together — labour departments tend to flag PT at the same time.

Five mistakes employers make with professional tax

1. Assuming head-office rules apply at the branch. Delhi has no PT; Maharashtra does. Every new state with employees means a fresh registration and routine.

2. Deducting but not depositing. Deducted money sitting in the company's account is the costliest mistake here. Maharashtra charges 1.25% per month interest on late payment plus penalties — never cheaper than paying on time.

3. One registration for all states. A Bengaluru plus Mumbai payroll needs both states' registrations, portals and due dates.

4. Skipping the PTEC. The employer deducts from staff — and never enrols the company itself. Both certificates matter.

5. Ignoring slab changes. West Bengal's October 2026 revision is the update payroll masters miss for a quarter. Review slabs every April and October.

Frequently asked questions

Is professional tax mandatory for employers?

Yes — in states that levy it. If your staff's salaries cross the nil slab, you must register, deduct, deposit and file returns. There is no opt-out.

Who actually pays — employer or employee?

It is the employee's tax. The employer deducts it from salary and deposits it. The money comes off the payslip; all the compliance work sits with the employer.

What is the maximum professional tax per year?

₹2,500 per person — a constitutional ceiling under Article 276. It is why Maharashtra bumps February to ₹300.

Do I need separate PT registration for each state?

Yes. Employees in different states fall under different registrations, slabs and portals. One national payroll, multiple state filings.

Is professional tax deductible for income tax?

Yes. PT paid is deductible from salary income, so the payslip deduction slightly reduces the employee's taxable income.

What happens if I never register?

Interest and penalties accrue from the date you became liable — not from the date you were caught. Register on time and it costs almost nothing.
