What is e-Prerana and who runs it
e-Prerana stands for Electronic Professional Tax Enrolment, Registration and Administration. It is the official digital system of the Commercial Taxes Department, Government of Karnataka, built to manage professional tax under the Karnataka Tax on Professions, Trades, Callings and Employments Act, 1976. The portal is accessible at pt.kar.nic.in and is the only recognised way to register, file returns and pay professional tax in the state.
Before e-Prerana, professional tax compliance meant physical visits to the local Professional Tax Office. Today, every step, from the first registration application to the annual return, happens online, and the acknowledgement, username and password for the portal arrive by SMS the same day you apply.
PTRC vs. PTEC: Which one does your business need?
| certificate | who needs it | what it covers |
|---|---|---|
| PTRC | Employers who pay salaries to staff working in Karnataka | Deducting and depositing professional tax from employee salaries |
| PTEC | Self-employed professionals, proprietors, firms, LLPs and companies | Paying professional tax on the entity's or professional's own income |
Most registered businesses in Karnataka need both certificates: a PTRC because they employ staff, and a PTEC because the entity itself, as a legal person carrying on a trade or profession, is also liable to pay professional tax on its own account. Sole proprietors and freelancers who do not employ anyone still need a PTEC.
Karnataka professional tax slab rates for 2026
The Karnataka Tax on Professions, Trades, Callings and Employments (Amendment) Act, 2025 raised the monthly exemption threshold from ₹15,000 to ₹25,000, effective 1 April 2025. Anyone still calculating professional tax on the older slab is either over-deducting from employees or under-remitting to the department.
| Monthly gross salary | Professional tax payable |
|---|---|
| Below ₹25,000 | Nil |
| ₹25,000 and above | ₹200 per month for 11 months, ₹300 in February |
The annual maximum works out to ₹2,500, which is also the constitutional ceiling on professional tax across India. Self-employed persons and entities registered under PTEC pay this same ₹2,500 as a flat annual amount, due by 30 April of the financial year.
How to register on e-Prerana, step by step
- Go to pt.kar.nic.in and open New RC Request under e-Services for a PTRC, or New Enrolment for a PTEC.
- Enter PAN, business constitution, address, and the nature of trade or profession.
- Upload the requested documents: PAN card, address proof, and incorporation certificate for companies or ID proof for proprietors.
- Submit the form. The portal generates a unique acknowledgement number.
- Collect your username and password by SMS on the registered mobile, then log back in to download the certificate once the Professional Tax Officer processes the application.
Filing returns and paying tax
- Employers must deposit deducted professional tax by the 20th of the following month and file returns on the same schedule (monthly or quarterly, depending on liability). Self-employed PTEC holders pay the flat ₹2,500 by 30 April each year through the annual return. Payments are made through the e-Payment option on the portal, which generates a PRN or PTN number for your records.
Common mistakes that cost Karnataka businesses money
- Still deducting on the pre-2025 slab (the old ₹15,000 threshold), which either over-collects from staff or leaves a mismatch during audit.
- Applying for one PTRC to cover every branch. Each operational location in Karnataka needs its own registration and branch-specific payment credentials.
- Trying to clear several missed months in a single combined filing. The portal accepts only one month per return, so a backlog has to be cleared month by month.
- Registering the business for PTRC but forgetting the entity itself also needs a PTEC.
Penalties for late registration or payment
Sections 10 and 11 of the Karnataka PT Act impose interest of 1.25% per month on unpaid tax, along with a discretionary penalty of up to 50% of the amount due. Because the interest compounds monthly and the department can also levy the penalty independently, a small missed payment can grow into a meaningful liability by the time it is noticed at audit or GST cross-verification.
