Form 4A Filing in Karnataka: Annual Professional Tax Return Guide for Businesses

Published On: Apr 18, 2025Last Updated: Apr 18, 20255.5 min read

Professional Tax (PT) is one of the most overlooked yet mandatory state-level compliances for businesses operating in Karnataka. If your business is registered under the Karnataka Goods and Services Tax Act, 2017, it is mandatory to file an Annual Professional Tax Return in Form 4A on or before 30th April every year.

This requirement applies regardless of the business’s operational status. Non-compliance may result in interest, penalties, and legal consequences under the Karnataka Tax on Professions, Trades, Callings and Employments Act, 1976.

In this guide, we help you understand the scope of this obligation, the filing process, applicable penalties, and how LegalWiz.in can support you in staying compliant with Karnataka’s Professional Tax regulations.

Understanding Professional Tax in Karnataka

Professional Tax in Karnataka is levied on individuals and entities engaged in professions, trades, and employment. The tax is governed by the Karnataka Tax on Professions, Trades, Callings and Employments Act, 1976 and administered by the Commercial Taxes Department.

There are two components to PT registration:

  • Professional Tax Enrollment Certificate (PTEC): Required for business entities and self-employed professionals
  • Professional Tax Registration Certificate (PTRC): Required for employers to deduct and pay PT on behalf of employees

Every business entity must obtain a PTEC and pay a fixed amount of Professional Tax annually, currently set at INR 2,500 per place of business. This tax payment is reported by filing Form 4A.

Applicability of Form 4A Filing

Form 4A is a mandatory annual return to be filed by all entities in Karnataka that hold a Professional Tax Enrollment Certificate (PTEC).

Who Needs to File Form 4A?

  • Any business entity registered under GST in Karnataka
  • Entities including sole proprietorships, partnership firms, LLPs, private limited companies, public limited companies, and other forms of businesses
  • Businesses holding a PTEC
  • Entities with or without any business activity during the financial year

Even if your business did not operate or generate revenue during the year, filing Form 4A is compulsory if you hold a valid PTEC.

Non-filing is treated as a compliance lapse and attracts penalties under the Professional Tax Act.

Due Date and Frequency

Form 4A is required to be filed once every financial year, and the due date is fixed.

  • Filing Frequency: Annual
  • Due Date: On or before 30th April of the following financial year
  • Applicable Period: April 1 to March 31 of the previous year

Example: For FY 2024-25, the return must be filed by 30th April 2025.

Late filing beyond this date may attract interest and penalties as defined under Sections 23 and 24 of the Karnataka PT Act.

Penalties for Non-Compliance

Karnataka’s PT law imposes strict consequences for late or non-filing of Form 4A:

  • Interest (Section 23): Interest at the rate of 1.25% per month on the tax amount due
  • Penalty (Section 24): Penalty up to 50% of the tax amount for delayed or non-filing

Apart from these, the department may initiate prosecution or suspend the enrollment certificate for persistent non-compliance.

Step-by-Step Filing Process for Form 4A

Form 4A must be filed online via the Karnataka PT e-filing portal: https://pt.kar.nic.in

Steps to File:

  1. Log in to the e-Prerana portal using your PTEC credentials
  2. Navigate to the Form 4A – Annual Return section
  3. Select the relevant financial year
  4. Enter required details including enrollment number, name, and tax amount
  5. Verify payment of the fixed tax (INR 2,500 per business location)
  6. Submit the form and download the acknowledgment
  7. Keep records of payment receipts and acknowledgments for audit purposes

If any discrepancy is found, the department may issue notices for clarification.

Documents Required for Filing

To file Form 4A, businesses must keep the following documents ready:

  • Copy of the Professional Tax Enrollment Certificate (PTEC)
  • GST Registration Certificate
  • PAN of the business entity
  • Proof of payment of INR 2,500 PT tax per location (challan)
  • Login credentials for the PT portal
  • Address proof of the business

Having these documents ensures quick and hassle-free filing.

Understanding the Role of Form 4A, Form 5A & Form 5 in Karnataka PT Compliance

While Form 4A is an annual return filed by businesses holding a Professional Tax Enrollment Certificate (PTEC), employers with Professional Tax Registration Certificate (PTRC) must file Form 5A on a monthly or quarterly basis for employee deductions. Additionally, they are also required to file an annual consolidated return in Form 5.

It’s essential to understand the distinction between these three forms to remain fully compliant under the Karnataka PT Act.
