ePay Tax vs old Challan 280

1. Portal Integration

- ePay Tax is built into the new income tax portal, so everything is in one place.

- Challan 280, however, was hosted on a separate NSDL website, requiring more steps and time.

2. PAN Auto-Fetch

- In ePay Tax, your PAN details are auto-filled once you log in, reducing errors.

- With Challan 280, you had to enter your PAN manually, which could easily lead to mistakes.

3. Payment Methods

- ePay Tax supports UPI, debit cards, net banking, and NEFT/RTGS—giving you full flexibility.

- Challan 280 offered limited payment modes like net banking or bank branch payments.

4. Challan Generation

- Using ePay Tax, your challan is generated instantly in real-time.

- With Challan 280, it could take longer and often required manual verification.

5. Tracking & History

- ePay Tax links your payments directly to your account. You can track your challans anytime.

- Challan 280 didn't have this feature—you had to manually save receipts or lose them.

6. DSC (Digital Signature Certificate) Support

- ePay Tax fully supports digital signature (DSC) authentication, making it more secure and ideal for professionals and businesses.

- Challan 280 offered no DSC support, which is a major drawback for those required to file using a DSC in income tax e-filing.

7. User Interface

- The ePay Tax system has a modern, mobile-friendly design, making navigation easy.

- Challan 280 had an outdated look and could be hard to use on mobile or low-speed connections.
