Quick answer
You need your PAN to register on the income tax e-filing portal. Here's the step-by-step and what you can do once registered.
On the income tax e-filing portal, your PAN serves as your user ID. So before registering, make sure your PAN is active and linked with your Aadhaar, as an inoperative PAN can block registration and filing.
Use the 'Register' option on the portal, enter your PAN, and provide your basic details — name, date of birth, contact number and email — matching your PAN records. The portal validates these against the PAN database, so they must match exactly.
You'll verify your mobile number and email through one-time passwords, and set a password for your account. Use a number and email you'll keep access to, since they're used for OTPs, alerts and notices.
Once registered, you can file your return, e-verify it, check your refund status, view your AIS and 26AS, pay advance or self-assessment tax, respond to notices, and link PAN with Aadhaar — all from one login.
Keep your registered mobile and email up to date, because important communications and OTPs go there. If you change your number, update it on the portal so you don't miss notices or get locked out at filing time.

Yes — your PAN is your user ID on the e-filing portal. An inoperative or unlinked PAN can block registration and filing, so ensure it's active and Aadhaar-linked first.
File and e-verify returns, check refund status, view AIS and 26AS, pay tax, respond to notices and link PAN-Aadhaar — all from one login once registered.
