What is professional tax in Bihar?

Professional tax is a state levy on professions, trades, callings and employments. The Constitution, under Article 276, permits states to impose it subject to an annual ceiling. Bihar imposes professional tax under the Bihar Tax on Professions, Trades, Callings and Employments Act, 2011 and associated rules.

The tax is separate from GST, income tax, and any fee charged for a business licence. A GSTIN does not automatically replace professional tax registration or enrolment.

The old article correctly explained the constitutional basis and distinguished employers from self-employed persons. This revised guide keeps those essential concepts but applies Bihar-specific slabs and procedures. Bihar’s schedule contains different classes of taxpayers, so not every individual or business should be assessed using a single salary table.

Quick answer: Depending on the relevant category, the Bihar schedule provides nil, ₹1,000, ₹2,000 or ₹2,500 per year. The applicable category and current notification must be checked first.

Professional tax rates in Bihar: statutory slabs (2026–27)

The published Bihar Commercial Taxes Department schedule lists the following income-based category. These are annual figures, not monthly deduction rates. For the applicable year, verify any subsequent amendment or notification before processing payroll.

Annual income	Published annual professional tax	Practical reading
Up to ₹3,00,000	Nil	At or below the threshold
Above ₹3,00,000 and up to ₹5,00,000	₹1,000	First taxable income band
Above ₹5,00,000 and up to ₹10,00,000	₹2,000	Second taxable band
Above ₹10,00,000	₹2,500	Highest income band

Other categories: The same statutory schedule also contains specific treatment for certain dealers, transport permit holders and other specified occupations or establishments. For example, the published schedule identifies turnover-based slabs for dealers in its specified VAT/CST category. This historical statutory label must not be automatically applied to every modern GST-registered business without reviewing the current legal position.

Who needs to pay or register for professional tax?

Employees

Salaried persons

Where tax is payable on employment income, the employer generally handles the prescribed deduction and remittance. Determine liability from the applicable annual income category and rules.

Employers

Businesses with employees

A covered employer generally requires registration to deduct and remit professional tax. Having a GST registration is not a substitute for the employer’s PT registration.

Professionals and traders

Self-employed persons

Individuals carrying on taxable professions or businesses may require enrolment in their own capacity, subject to the relevant category, thresholds and exceptions.

Proprietorships, firms, LLPs, companies, societies and other bodies should check their actual statutory classification. Merely having a particular legal constitution does not, without more, prove that a ₹2,500 charge applies.

Registration versus enrolment

Employer registration is associated with withholding/remittance from employees. Enrolment is associated with a liable person paying professional tax on their own profession, trade, calling or employment. In a particular business, both types of obligations can arise, but eligibility must be independently assessed.

How to apply for Bihar professional tax registration

The Bihar Professional Tax Rules, as amended, describe electronic employer registration using Form PT-I. The published rules refer to making the application within seven days after the employer becomes liable. Verify the applicable portal version and current instructions rather than relying on old screenshots or a generic GST-registration process.

Step 1 — Identify status. Determine whether the applicant needs employer registration, enrolment, or both.

Step 2 — Gather details. Prepare PAN, business name, contact information, address, employee information where applicable and documents requested by the department.

Step 3 — Access official services. Use the Bihar Commercial Taxes Department’s professional-tax registration service.

Step 4 — Verify contact details. Complete PAN, mobile and email validation according to the available application workflow.

Step 5 — Submit and retain evidence. Upload required supporting records and save the electronic acknowledgement.

Step 6 — Check certificate and obligations. Verify the issued registration or enrolment particulars, tax category, payment requirements and filing calendar.

The official registration guide and later rule amendments are different-age documents. If an older user manual shows a different form or outdated screen, follow the currently operational portal and applicable amended rules.

Professional tax deduction, payment and annual returns

Section 7 of the Bihar Act provides for returns and tax deposits according to the applicable rules. The published Bihar rules describe Form PT-VIII for the annual employer return and Form PT-IX for the annual enrolled-person return, generally on or before the end of November. Confirm the relevant financial year, active portal and any notifications extending or changing a deadline.

Compliance activity	Who typically handles it	Key point
Employer registration	Employer liable to deduct	Form PT-I under amended registration rules
Professional tax deduction	Registered employer	Follow Bihar-specific deduction and remittance provisions
Employer annual return	Registered employer	Form PT-VIII under published rules
Enrolled-person annual return	Person enrolled under the Act	Form PT-IX under published rules
Tax payment and acknowledgements	Employer or enrolled person as applicable	Keep challans, payroll reconciliation and return acknowledgements

Do not automatically use monthly professional-tax charts borrowed from Maharashtra, Karnataka or another state. Bihar has its own deduction timing and filing framework. An older version of this page presented a generic February-adjusted instalment example; that should not be relied on for Bihar payroll.

If you receive a discrepancy notice, verify the registration number, tax period, wage records, payments, statutory rate category and return filings before replying.

Examples: how the annual slabs work

Example A

₹2,80,000 annual income

Under the published income-based schedule, the amount is nil.

Example B

₹4,80,000 annual income

The indicated annual amount is ₹1,000, assuming the income-based category applies.

Example C

₹12,00,000 annual income

The indicated annual amount is ₹2,500, subject to the applicable classification.

These are illustrative calculations for the published income category, not determinations for a business classified under another statutory schedule entry.

Common professional tax mistakes to avoid

Using another state’s monthly deduction chart for Bihar employees.
Assuming a GSTIN automatically fulfils state professional-tax registration.
Confusing employer registration with an individual’s enrolment.
Applying turnover-based or transport-category rates to every business.
Failing to check the relevant tax period or an amended notification.
Not keeping employee-wise tax deductions, payment challans and return acknowledgements reconciled.
Repeating a deadline from an old article without reviewing current portal instructions.

Under Section 7, failure to comply without reasonable cause may attract statutory action, including the specified late-return or payment penalty after an opportunity of hearing. Do not assume that this is the only possible consequence; assess the particular contravention under the relevant provisions.
