Managing Professional Tax (PT) in Karnataka has become slightly more complex this year. Following the Karnataka Tax on Profession (Amendment) Act, 2025, the state has revised its slab structure and annual caps. For SMEs, staying compliant means more than just a monthly deduction — it requires precise accounting for a fluctuating February rate and strict adherence to new filing timelines.
The deduction for the month of February must be adjusted to ₹300 (instead of the usual ₹200) to reach the new annual cap of ₹2,500. Missing this adjustment creates both a compliance gap and a reconciliation headache.
1. Revised Karnataka PT Slab Rates for FY 2025-26
As of April 1, 2025, the primary threshold for Professional Tax eligibility has been updated. The previous slab for individuals earning between ₹15,000 and ₹24,999 has been abolished (now Nil), while the rate for higher earners has seen a targeted increase.
| Monthly Gross Salary | Monthly PT Deduction | Total Annual Tax |
|---|---|---|
| Up to ₹24,999 | Nil | ₹0 |
| ₹25,000 and Above | ₹200 (April–Jan & March) ₹300 (February Only) | ₹2,500 |
The most critical change for your payroll team is the February Surge. To reach the new annual cap of ₹2,500 (up from ₹2,400), the deduction for the month of February must be manually or automatically adjusted to ₹300.

2. Essential Deadlines: PTEC vs. PTRC
In Karnataka, businesses typically deal with two types of Professional Tax requirements. Missing either can lead to immediate interest charges.
Monthly Payment (PTRC — Registration Certificate)
Employers who deduct tax from their employees' salaries must remit these funds to the state government monthly.
20th of the succeeding month. Example: PT deducted for December 2025 must be paid by January 20, 2026.
Annual Enrollment Fee (PTEC — Enrollment Certificate)
Every business entity (Company, LLP, etc.) must pay its own professional tax, and self-employed professionals must do the same.
- PTEC Deadline: 30th of April of the beginning of the financial year
- PTEC Amount: Typically ₹2,500 per annum
Annual Return (Form 5)
All registered employers must file an annual return in Form 5, summarising the year's total deductions and payments. Deadline: 30th of May following the end of the financial year.
3. Penalties for Non-Compliance
Karnataka's Commercial Tax Department enforces strict penalties for delays. In an era of automated notices, "forgetting" the February hike or the 20th of the month can be costly.
- Interest on Late Payment: 1.5% per month on the outstanding tax amount.
- Non-Deduction Penalty: If an employer fails to deduct PT from eligible employees, they may be liable to pay the tax themselves plus a penalty.
- Late Filing Fee: A penalty (which can go up to 50% of the tax due) may be levied for failure to file returns within the stipulated time.
Did you know? Senior citizens (above 60 years of age) are exempt from paying Professional Tax in Karnataka. Ensure your payroll software is configured to stop deductions automatically once an employee reaches this milestone.
4. Actionable Steps for SMEs
Update Employee Data
Audit your payroll to identify all employees crossing the ₹25,000 monthly gross salary mark — these employees now trigger PT liability.
Configure the 'February Rule'
Ensure your payroll logic is set to deduct ₹300 in February and ₹200 for all other months. Manual adjustments are prone to Spreadsheet Errors — automate this.
Set Calendar Reminders
Set recurring alerts for the 20th of every month (PTRC) and April 30th (PTEC). Better yet, let ZiacPay's compliance dashboard handle this automatically.
