In plain language
What Section 501 actually says
Section 501 of the Income-tax Act, 2025 is the master provision that tells the Income-tax Department how it may legally deliver a notice, summons, requisition, order or any other communication to you. It does not create any tax, penalty or demand by itself — it is purely a machinery (procedural) section that governs the mode of service. It replaces and modernises the old Section 282 of the Income-tax Act, 1961, carrying the same idea forward with an even stronger digital-first tilt, effective from 1 April 2026.
- Section 501(1) lists the permitted methods of service — by post; by a courier service approved by the CBDT; in the manner the Code of Civil Procedure, 1908 provides for service of summons; as an electronic record under Chapter IV of the Information Technology Act, 2000; or by any other prescribed means.
- Section 501(2) empowers the Central Board of Direct Taxes (CBDT / "the Board") to make rules on the addresses — including e-mail addresses — to which communications may be delivered.
- Section 501(3) defines "electronic communication" broadly — a message created, transmitted or received on any computer, computer resource or communication device, including text, image, audio, video and attachments.
Who it applies to
It applies to every person the Department needs to reach — individuals, HUFs, firms, LLPs, companies, trusts, and their legal representatives, agents or successors. It equally binds the tax authority: an assessment, penalty or reassessment order is only valid if the underlying notice was served in one of the modes Section 501 allows. Faulty service can make the whole proceeding legally vulnerable.
The permitted addresses (Rule 232)
The draft rules (Rule 232) list where the Department may send communications. This matters because "I never received the notice" is a common dispute. Permitted addresses include:
- The address in the PAN database.
- The address in your latest or relevant income-tax return.
- The registered office of a company (from the MCA portal).
- Address available with UIDAI (Aadhaar), other government bodies or utility providers.
- The address given in earlier correspondence.
- For e-mail: the e-mail in your return, on the e-filing portal, in your PAN application, or on the MCA site.
Important safeguard: if you have given the officer a written alternative address, that instruction overrides the default addresses above.
How it interacts with faceless assessment
Section 501 is the backbone of the faceless / e-proceedings regime. Almost all modern notices are pushed to your e-filing account and your registered e-mail; a communication placed in your registered account on the portal is treated as validly served. This is why keeping your e-mail and mobile updated on the portal is now a compliance necessity, not an option.
Practical implications for taxpayers
- Check the portal and e-mail regularly — deemed service starts the clock for your reply, and missing it can lead to a best-judgment or ex-parte order.
- Keep PAN and return details current — an old address in the PAN database is still a valid service address.
- Update address in writing when you move, so the officer uses the correct address.
- Service on a company at its registered office, or on an authorised agent, is valid even if it does not reach the exact person handling tax.
💡 Example
Worked example 1 — deemed electronic service. Priya, a salaried taxpayer in Jaipur, filed her return giving e-mail priya@example.com and her mobile. On 12 May 2026 the Department uploads a Section 268 scrutiny notice to her e-filing account and e-mails it. Even though Priya opens it only on 5 June, service is treated as complete on 12 May 2026 (the date it entered her registered account/e-mail). Her time to respond runs from that date — so a 15-day response window would expire around 27 May, not 20 June. Ignoring the portal cost her nearly a month.
Worked example 2 — company registered office. ABC Pvt Ltd shifted its working office but never updated the MCA registered office. A penalty notice is couriered (via a CBDT-approved courier) to the old MCA-registered address and is received by the watchman. Under Section 501 read with Rule 232, this is valid service. The company later argued "we never got it," but because the registered office address is a permitted address, the ₹10,000 penalty order under Section 449 stood.
Relatable story. Ramesh, a small trader, changed his e-mail years ago but never updated the e-filing portal. A reassessment notice went to his old inbox and the portal. He missed it entirely and an ex-parte order raised a demand of ₹2.4 lakh. His CA had to file a delayed appeal explaining the mis-service. The lesson: under Section 501, the law assumes you are reachable at the addresses on record — so keeping them current is the cheapest tax insurance you can buy.
| Mode of service (Sec. 501) | Legal basis / condition | When service is treated complete |
|---|
| By post (registered/speed post) | Sent to a permitted address under Rule 232 | On delivery; presumed served if correctly addressed |
| Approved courier | Courier must be approved by CBDT | On delivery to the address |
| Manner under CPC, 1908 | Same rules as service of a court summons | As per CPC (personal delivery / affixture) |
| Electronic record (IT Act, 2000, Ch. IV) | E-mail / upload to registered e-filing account | When it enters the registered account or e-mail |
| Any other prescribed means | As notified by the Board | As prescribed in the rule |

Frequently asked questions
What does Section 501 of the Income-tax Act, 2025 deal with?
It is a procedural section that lays down how the Income-tax Department may serve notices, summons, requisitions and orders — by post, approved courier, the CPC manner, or as an electronic record. It replaces Section 282 of the 1961 Act.
Is a notice sent only by e-mail valid?
Yes. Section 501(1) expressly allows service as an electronic record under Chapter IV of the IT Act, 2000, and a notice e-mailed to your registered e-mail or uploaded to your e-filing account is valid service.
When is electronic service treated as complete?
Generally when the communication enters your registered e-filing account or registered e-mail, not when you actually open or read it. This is why the response time can start before you see the notice.
Can the Department send a notice to my old address?
Yes, if it is a permitted address under Rule 232 — such as the address in your PAN database, latest return, or MCA registered office. That is why you must update your details when you move.
What if I gave the officer a different address in writing?
A written instruction giving an alternative address overrides the default addresses. The officer should then use the address you specified for service.
What is the difference between Section 501 and old Section 282?
Both cover service of notice, but Section 501 of the 2025 Act is more digital-first, expressly defines electronic communication (audio, video, attachments) and ties service closely to the faceless e-proceedings framework.
What happens if I miss a validly served notice?
The Department can proceed ex-parte or make a best-judgment assessment, and may levy a penalty under Section 449. Since service is often deemed complete on upload, regularly checking the portal is essential.
