April 1, 2026, is a landmark day in India’s tax history.
On this day, the decades-old Income Tax Act of 1961 is replaced by the Income Tax Act of 2025.
This change may cause confusion, especially for employees whose March 2026 salary is credited on April 1 instead of March 31.
Why? Because in India, taxes are not based on when you earned your salary—they are based on when the money actually reaches your account.
Payment Date Rules: The Real Game-Changer
The Income Tax Department follows the “pay-as-you-earn” principle.
This means the payment date decides which tax rules apply.
Case 1: If your March salary is credited on or before March 31, 2026, the old Income Tax Act, 1961 applies.
You will report this salary under the financial year 2025-26.
Case 2: If your March salary is credited on or after April 1, 2026, the new Income Tax Act, 2025 applies.
You will report this under the financial year 2026-27.
So even if you worked in March, the new tax law may apply if your payment arrives after April 1.
This can affect tax planning for many employees.
Section 392(1): What’s New?
Earlier, Section 192(1) was used to deduct TDS from salaries.
From April 1, 2026, this is replaced by Section 392(1).
Here’s what changes:
Employers will deduct tax based on the tax year in which the salary is paid.
The confusing terms “Previous Year” and “Assessment Year” are removed.
Now, only “Tax Year” is used, which refers to the financial year.
Your in-hand salary will now reflect deductions according to the new tax rates under the Tax Year.
This makes tax calculations simpler but requires employees to be aware of the payment date to avoid surprises.
