Forms, Verification and Mode of Filing Income Tax Returns

Updated 10 October 2026 · Fact-checked

A return of income must be filed in the prescribed form, signed and verified by the right person, and furnished in the prescribed mode. Pick the form by assessee type and nature of income, check whether electronic filing is compulsory, then verify by an electronic method or a signed ITR-V. Rules prescribe these details.

Understand Forms, Verification and Mode of Filing Returns

The Income-tax Act, 2025 says that a return must be furnished, but the fine detail sits in rules. Section 533 lets the Board make rules on the form and manner of returns, the classes of persons who must file electronically, the documents that are not attached to the return, and how a document is verified. So "which form" and "how to verify" are rule-based questions. Always check the form and rule notified for the tax year.

The form depends on who you are and what income you have. The broad pattern of the ITR series: ITR-1 for eligible resident individuals with salary, one house property and other-source income (a HUF cannot use it); ITR-2 for individuals and HUFs with no business or profession income; ITR-3 for individuals and HUFs with business or profession income; ITR-4 for eligible resident individuals, HUFs and firms (other than LLPs) opting for presumptive taxation; ITR-5 for firms, LLPs, AOPs and BOIs; ITR-6 for companies (other than those claiming exemption for charitable or religious property); ITR-7 for trusts, institutions and certain other persons. Eligibility limits and exclusions change, so read the instructions of the form for the year.

A return is not complete until it is verified. The person who signs must be the person the rules allow. The signatory order below comes from the rules notified under the Act, not from section 533 itself, so check the exact rule for the tax year. For a company, this is normally the managing director. If he is not available or there is no managing director, any director signs. If the company has no director in India, an authorised person may sign. A liquidator signs for a company in liquidation. For a firm, the managing partner signs, or any partner who is not a minor if there is no managing partner or he is unable to sign. For a HUF, the karta signs, or any adult member if the karta is absent or incapacitated. An individual signs himself, or an authorised person signs if he is abroad, mentally incapacitated, or in other cases the rules allow.

The mode of filing is also prescribed. Certain classes must file electronically under the rules. Companies are required to file electronically. Others, such as persons whose accounts must be audited under the Act, are covered by the rules. Verification can then be done electronically, for example through Aadhaar OTP, net-banking or bank-account based electronic verification code (EVC), or a digital signature, where the rules permit the method for that assessee. The other route is to send a signed physical ITR-V to the central processing centre within the prescribed time. Some classes may be required to verify by digital signature, while others may use EVC. The rules for the tax year decide which applies.

This ties to faceless assessment. Under section 273, communication between the National Faceless Assessment Centre and the assessee is exclusively by electronic mode, through the assessee's registered account on the designated portal. So a correctly registered and verified e-filing account matters beyond filing day.

Key rules to remember

Rule-making power on returns: Section 533(2): rules may prescribe form, manner, electronic classes and verification; Cite section 533(2)(j), (r) and (s) when the question asks where the forms and verification procedure come from. Clause (j) covers classes required to file electronically, (r) the form and manner of furnishing, and (s) how a document is verified.
Company signatory: Managing director → any director (if MD absent, unable, or none) → authorised person (if no director in India) → liquidator (in liquidation); Write the order as laid down in the rules notified under the Act. Examiners test the fallback. Check the exact rule for the tax year.
Firm signatory: Managing partner → any partner who is not a minor; For an LLP, the designated partner is the usual signatory.
HUF signatory: Karta → any adult member (if karta absent or incapacitated); A minor member cannot sign.
Individual signatory: Himself → authorised person (if abroad, mentally incapacitated, or as rules permit); The authorised person must hold a valid power of attorney.
Form map: ITR-1: eligible resident individuals; ITR-2/3: individuals and HUFs; ITR-4: eligible resident individuals, HUFs and firms (other than LLPs) under presumptive taxation; ITR-5: firm, LLP, AOP, BOI; ITR-6: company; ITR-7: trusts and institutions; Eligibility limits change by year. Always check the instructions of the form notified for the tax year.
Faceless communication: Section 273(7): communications between the National Faceless Assessment Centre and the assessee are exclusively by electronic mode; The faceless assessment runs through the assessee's registered account on the designated portal (section 273(13)).

How to solve Forms, Verification and Mode of Filing Returns questions

Use this order for any question on forms, signing, verification or mode of filing.

1Identify the assessee type: individual, HUF, firm, LLP, company, trust, or other person.
2Note the nature of income: salary, house property, other sources, business or profession, presumptive income, capital gains.
3Match to the form: individual or HUF first by business income, then firm or company by type.
4Check whether electronic filing is compulsory. Companies are required to file electronically under the rules. Audit cases are covered by the rules.
5Decide the signatory using the order in the rules for that assessee, and apply the fallback if the first person is absent, unable or missing.
6State the verification method: electronic route (EVC or digital signature, where the rules permit) or signed ITR-V, noting where a digital signature is required.
7Close with the source: rules made under section 533, and mention section 273 if the question touches faceless proceedings.

Quickest way: Assessee-first shortcut

When to use it: Use this for one- or two-mark MCQs and short-answer parts when time is tight.

Read the assessee type first. Company means ITR-6 and electronic filing, verified by digital signature or, where the rules permit, EVC. Firm, LLP, AOP or BOI generally means ITR-5 (a firm other than an LLP under presumptive taxation can use ITR-4).
For individuals and HUFs, ask: business income? If yes, ITR-3, or ITR-4 if eligible under presumptive taxation. If no, ITR-1 for an eligible resident individual (never a HUF), else ITR-2.
For signatory, ask who the head is: MD for a company, managing partner for a firm, karta for a HUF.
If the question says that person is absent, abroad or unavailable, jump to the fallback: any director, any adult partner, any adult member.

Common mistakes in Forms, Verification and Mode of Filing Returns

Choosing ITR-1 for an individual with business income or for a HUF
Students remember ITR-1 as the simplest form.
Fix: ITR-1 is only for eligible resident individuals, so a HUF cannot use it. Business income needs ITR-3, or ITR-4 for eligible resident individuals, HUFs and firms (other than LLPs) opting for presumptive taxation. Always check the form instructions.
Allowing any director to sign a company return in every case
The fallback is remembered but not the first-in-line rule.
Fix: Write the managing director first, then any director only when the MD is absent, unable or does not exist.
Letting a minor partner or minor member sign for a firm or HUF
The phrase "any partner" is read literally.
Fix: The fallback is any partner who is not a minor and any adult member.
Treating the return as filed once the form is uploaded
Students confuse uploading with filing.
Fix: A return is incomplete until verified. Name the electronic method or the signed ITR-V sent to the central processing centre within the prescribed time.
Quoting a section number from the old Act for forms or verification
Old notes use the Income-tax Act, 1961 numbers.
Fix: Use the Income-tax Act, 2025. For rule-making on forms, mode and verification, cite section 533(2). For faceless assessment, cite section 273. If unsure of a number, state the rule without it.
Saying faceless assessment means no communication at all
The word "faceless" is misread.
Fix: Communication takes place, but through the National Faceless Assessment Centre and exclusively by electronic mode, using the registered account on the designated portal.

Worked examples

Example 1

Mr Rakesh Iyer, a resident individual, has salary of ₹18,00,000, bank interest of ₹40,000 and income from one let-out house property. He has no business income. Which form is he likely to use, and who verifies the return?

Show the solution

Assessee type: resident individual.
Income: salary, one house property and interest only. No business or profession income and no capital gains.
This fits the pattern for ITR-1, subject to the eligibility limit and exclusions in the form instructions for the tax year.
Signatory: Mr Iyer himself. An authorised person signs only if he is abroad, mentally incapacitated, or as permitted by the rules.
Verification: electronic method such as Aadhaar OTP or net-banking EVC, or a signed ITR-V sent to the central processing centre within the prescribed time.

Answer: ITR-1 (subject to eligibility), signed and verified by Mr Iyer himself, electronically or by ITR-V.

Example 2

Kaveri Textiles Pvt Ltd has a managing director, Mr Mehta, who is abroad for the whole of the year. The company has two other directors in India. Who signs the return, which form is used, and must it be filed electronically?

Show the solution

Assessee type: company, so the form is ITR-6 (it does not claim exemption for charitable or religious property).
Signatory: the managing director is the first choice, but he is absent from India.
Under the rules notified under the Act, the fallback is any director. Since two directors are in India, either can sign. An authorised person is needed only if no director is in India. Check the exact rule for the tax year.
Mode: a company is required to file electronically under the rules. Verification is by digital signature or, where the rules permit, EVC.
Link to 2025 Act: the form, manner and verification are prescribed under rules made under section 533(2).

Answer: ITR-6, signed by either of the two directors in India, filed electronically and verified by digital signature or, where the rules permit, EVC.

Exam tips

Expect one MCQ on the form for a given assessee. Learn the form map by assessee type, not by number alone.
In written answers, list the signatory in order and add the fallback. That earns separate step marks.
Name the Act correctly as the Income-tax Act, 2025 and use the term tax year. Cite section 533(2) for rule-making and section 273 for faceless assessment only when relevant.
Mention verification as a separate step after filing. Examiners often award a mark for it.
Because forms and limits are notified yearly, avoid quoting income limits unless the question gives them.

Practice questions from Filing of Return of Income

Forms, Verification and Mode of Filing Returns: frequently asked questions

Which ITR form applies to which assessee?

It depends on the type of assessee and the income. Eligible resident individuals with simple income use ITR-1. Individuals and HUFs without business income use ITR-2, and with business income ITR-3. ITR-4 is for eligible resident individuals, HUFs and firms (other than LLPs) under presumptive taxation. Firms, LLPs, AOPs and BOIs use ITR-5, companies ITR-6, and trusts and institutions ITR-7. Check the form instructions for the tax year.

Who can verify the return of income for a company and a firm?

Under the rules notified under the Act, the managing director signs for a company. If he is absent, unable or there is none, any director signs, and an authorised person signs if no director is in India. For a firm, the managing partner signs, or any partner who is not a minor if there is no managing partner or he is unable. Check the exact rule for the tax year.

Is e-filing of the return of income compulsory?

Companies are required to file electronically under the rules. For other classes, the rules made under the Act specify who must file electronically, including many cases where accounts must be audited. Check the rules for the tax year for the exact classes.

How do I verify an income tax return electronically?

You can use an electronic method such as Aadhaar OTP, a net-banking or bank-account based electronic verification code, or a digital signature, where the rules permit the method for your category. If you do not verify electronically, you can send a signed ITR-V to the central processing centre within the prescribed time.
