Professional tax in Karnataka applies to individuals engaged in professions, trades, callings, and employment. E-commerce sellers do fall under the scope.
WHO MUST REGISTER IN KARNATAKA:
If you are operating as a sole proprietor or business selling goods online from Karnataka, you must obtain a Professional Tax Enrollment Certificate (PTEC) from the Commercial Taxes Department.
ANNUAL PTEC RATE (FY 2025-26):
Karnataka PT is calculated on MONTHLY INCOME. For self-employed individuals and business owners with annual income above Rs 2.16 lakh (Rs 18,001 per month), the tax is Rs 2,500 per year (collected in two installments: Rs 1,250 by July 31 and Rs 1,250 by January 31).
HOW TO REGISTER:
1. Visit the Karnataka PT portal: pt.kar.nic.in
2. Click on New Registration > Enrolment
3. Fill in your name, PAN, business name, trade/business type
4. Select "e-commerce" or "trader" as your nature of business
5. Submit and receive your Enrollment Certificate (EC Number)
IMPORTANT: If you also employ any staff (even part-time delivery staff, accountants, etc.) who earn above Rs 15,000/month, you also need a PTRC to deduct PT from their salary.
PENALTY FOR NON-REGISTRATION: Interest at 1.25% per month on tax due, plus penalty up to 50% of tax amount.
