1. Why Section 91 matters
GST law must still work when the person for whose benefit a business is carried on cannot legally or practically conduct that business personally.
Imagine that a minor inherits a commercial property and a business connected with it. The minor cannot simply operate the business in the same way as an adult. A guardian or another legally responsible person may conduct the business on the minor's behalf.
Section 91 provides a clear GST rule for this situation. Where the business is carried on by a guardian, trustee or agent of a minor or other incapacitated person, on behalf of and for the benefit of that person, GST tax, interest or penalty is levied upon and recoverable from the guardian, trustee or agent.
2. What people actually search for
This page is designed around practical search questions such as:
The objective is to answer the practical question behind the search: if the actual business owner cannot conduct the business personally, who is responsible for GST compliance and payment?
3. Section 91 in simple language
Suppose a 16-year-old minor inherits a business that generates taxable supplies. A guardian is legally managing the business for the minor's benefit.
The business still has GST obligations. The minor cannot simply be treated as though the business has no GST because the owner is a minor.
Section 91 says that the GST tax, interest or penalty is levied upon and recoverable from the guardian in the same manner and to the same extent as it would have been determined and recovered from the minor if the minor were a major and were conducting the business personally.
4. Complete statutory structure
| Element | Meaning |
|---|---|
| Business | There must be a business in respect of which tax, interest or penalty is payable under the CGST Act. |
| Protected person | The business is connected with a minor or other incapacitated person. |
| Responsible person | A guardian, trustee or agent carries on the business. |
| Purpose | The business is carried on on behalf of and for the benefit of the minor/incapacitated person. |
| GST liability | Tax, interest or penalty is levied upon and recoverable from the guardian, trustee or agent. |
| Extent | The determination and recovery operate in the same manner and to the same extent as they would for the protected person if capable of conducting the business. |
The current CGST Act text states this framework without a separate monetary threshold or special rate.
5. Who can be covered?
Section 91 names three categories:
Guardian
A person responsible for managing the affairs/business of a minor or other incapacitated person.
Trustee
A trustee who carries on the business on behalf of and for the benefit of the protected person.
Agent
An agent who carries on the business on behalf of and for the benefit of the protected person.
Protected person
The minor or other incapacitated person for whose benefit the business is carried on.
The section should not be expanded to every person who happens to provide administrative help. The statutory relationship and purpose of the business matter.
6. The business condition
Section 91 is not a general provision about a person's private property or personal income. It specifically refers to a business in respect of which tax, interest or penalty is payable under the CGST Act.
Therefore, the first practical question is:
The answer should be supported by ownership documents, guardianship/trust/agency documents, GST registration records, books and actual business arrangements.
7. Meaning of “on behalf of and for the benefit”
These words are central to Section 91.
They indicate that the guardian, trustee or agent is not simply operating an unrelated business of their own. The business is being carried on for the protected person's benefit.
| Situation | Section 91 analysis |
|---|---|
| Guardian manages inherited business for minor | Strong factual fit with the section. |
| Trustee operates business/assets for beneficiary | May fall within the provision where the statutory conditions are satisfied. |
| Agent operates a business belonging to or for benefit of minor | Potentially covered. |
| Person independently operates own business and merely helps a minor separately | Do not automatically treat this as Section 91. |
8. What liabilities are covered?
Section 91 expressly covers three categories:
GST payable under the Act.
Statutory interest associated with the tax liability.
Penalty payable under the applicable GST provisions.
The amount can be levied upon and recovered from the guardian, trustee or agent in the statutory manner.
This means the person managing the business cannot treat GST as merely an administrative formality. The financial consequences can extend to the tax, interest and penalty arising under the Act.
9. What does “in like manner and to the same extent” mean?
This phrase prevents the representative arrangement from creating a special GST discount or reduced liability merely because the business belongs to a minor or incapacitated person.
For example, if a taxable business would have been required to pay GST and comply with the Act if conducted by a capable person, the guardian/trustee/agent does not get a reduced tax obligation simply because they are managing it for someone else.
10. Guardian example
A minor inherits a taxable trading business. The guardian manages purchases, sales, employees, banking and GST compliance for the minor.
The guardian should ensure that the business is correctly registered where required, invoices are issued, returns are filed, tax is paid and records are maintained.
If GST tax, interest or penalty becomes payable, Section 91 provides the statutory mechanism under which the amount can be levied upon and recovered from the guardian in the specified manner.
11. Trustee example
A trust arrangement places a business asset or business activity under the management of a trustee for the benefit of a person who cannot personally conduct the business.
The GST analysis should begin with the trust deed and actual business arrangement. If the trustee is carrying on the business on behalf of and for the benefit of the protected person, Section 91 may apply.
The trustee should keep the trust deed, GST registration documents, books, invoices, bank records and evidence showing the capacity in which the business is operated.
12. Agent example
An agent may be appointed to operate a business for the benefit of a minor or incapacitated person.
The word “agent” should not be read so broadly that every ordinary employee or service provider becomes a Section 91 representative. The actual legal and commercial relationship should be examined.
Where the statutory conditions are satisfied, the agent can become the person from whom tax, interest and penalty are levied and recovered under Section 91.
13. Business of a minor
A minor's age does not by itself make every activity a GST business or automatically create Section 91 liability. The provision becomes relevant when there is a business in respect of which GST tax, interest or penalty is payable and that business is carried on by a guardian, trustee or agent for the minor's benefit.
For professional review, establish:
14. Other incapacitated person
Section 91 is not limited to minors. It also refers to an other incapacitated person.
The relevant question is whether the person is in a legal or factual situation in which a guardian, trustee or agent is carrying on the business on that person's behalf and for that person's benefit.
Because “incapacitated” can involve different legal circumstances, the underlying legal documents and applicable personal/guardianship law should be reviewed rather than assuming that every illness, absence or inability to manage accounts creates Section 91 status.
15. GST registration and authorised signatory
Section 91 is a liability provision. It should not be confused with the separate GST registration and authorised-signatory rules.
Where a person is legally managing the business, the registration records should accurately reflect the taxable person's details and the persons authorised to act for that taxable person.
GST registration rules also provide for signing and filing documents through persons competent or authorised to act on behalf of the taxable person. For example, CBIC's registration rules recognise guardians/competent persons for individuals who are mentally incapacitated and authorised persons for other categories.
16. GST returns and compliance
The representative managing the business should treat GST compliance as an ongoing process:
| Area | Practical responsibility |
|---|---|
| Registration | Ensure registration is obtained/maintained where required. |
| Invoices | Issue proper tax invoices/bills of supply as applicable. |
| Returns | File the applicable GST returns on time. |
| Tax payment | Reconcile output tax, ITC and cash/credit ledger. |
| Notices | Track scrutiny, audit, assessment and recovery communications. |
| Records | Maintain books and GST documents required under the Act and Rules. |
17. Books and records
Section 91 does not eliminate the ordinary record-keeping requirements. The business should maintain the records required under Section 35 and the relevant Rules.
Useful records include:
CBIC's accounting rules separately require agents covered by the GST framework to maintain records of authorisation, goods/services received and supplied on behalf of principals, accounts furnished to principals and tax paid.
18. Recovery and departmental proceedings
If tax, interest or penalty becomes payable, the representative should not assume that Section 91 is only an internal accounting rule. The provision expressly states that the amount is levied upon and recoverable from the guardian, trustee or agent.
Accordingly, if a notice or recovery communication is received, the first step should be to identify:
- The underlying taxable person
- The business involved
- The legal capacity of the representative
- The tax period
- The tax, interest and penalty amount
- The assessment/demand order
- Payments already made
- Any appeal or stay
The ordinary GST determination and recovery provisions continue to be relevant alongside Section 91.
19. What Section 91 does not mean
20. Construction and infrastructure examples
Inherited construction business
A minor inherits a construction-related business and a guardian manages contracts, invoices, subcontractors and GST returns. The guardian should establish the legal capacity in which the business is being managed and maintain complete GST records.
Trust-managed project asset
A trustee manages a commercial property/business activity for a protected beneficiary. The trust deed, business arrangement and GST registration should be reviewed together.
Agency arrangement
An agent is appointed to operate a taxable business for the benefit of a minor. The agency documentation and actual conduct should clearly establish the representative capacity.
21. Detailed practical cases
Case 1 — Minor owns taxable business
Guardian operates the business for the minor's benefit. Section 91 should be examined because the statutory representative relationship is present.
Case 2 — Minor only owns an investment
Ownership of an investment by itself does not automatically mean there is a business being carried on under Section 91.
Case 3 — Guardian manages business temporarily
Examine whether the guardian is actually carrying on the business on behalf of and for the benefit of the minor.
Case 4 — Trustee manages business for beneficiary
Review the trust deed and actual business operations to determine the Section 91 relationship.
Case 5 — Agent is appointed
Preserve the agency agreement and records showing that the business is being conducted for the protected person's benefit.
Case 6 — GST demand arises
Identify the tax period, tax, interest and penalty and establish the representative capacity before responding.
Case 7 — ITC dispute
Maintain purchase invoices, GSTR-2B reconciliation, payment records and other ITC evidence. Section 91 does not remove ordinary ITC conditions.
Case 8 — RCM liability
If the business has reverse-charge obligations, those liabilities must be included in the GST compliance review.
Case 9 — Business expands
Changes in turnover, registrations or places of business should be handled under the normal GST framework.
Case 10 — Representative changes
Document when a guardian, trustee or agent ceases or another person takes over and update relevant records/authorisations.
Case 11 — Departmental notice
Do not respond only by stating that the business belongs to a minor. Address the statutory facts and the actual GST liability.
Case 12 — Recovery stage
Reconstruct the demand, payments, appeal status and representative authority before dealing with recovery.
22. Professional compliance workflow
Determine who owns/benefits from the business.
Guardian, trustee or agent.
Guardianship/trust/agency documents.
Confirm registration and authorised persons.
GSTR-1, GSTR-3B and applicable returns.
Output tax, ITC, RCM and cash/credit ledgers.
Keep business and representative documents.
Track scrutiny, audit and assessment.
Review tax, interest, penalty and payments.
Respond using the correct statutory framework.
23. Internal controls
| Control | Recommended practice |
|---|---|
| Legal-capacity file | Keep guardian/trust/agency documents together with GST records. |
| GST calendar | Track every applicable filing and payment deadline. |
| Return review | Document review before filing. |
| ITC reconciliation | Maintain invoice-level reconciliation where relevant. |
| Notice register | Track every departmental communication and deadline. |
| Bank reconciliation | Match tax payments with electronic ledgers. |
| Representative changes | Update authorisations and GST records promptly. |

26. Section 89 vs Section 90 vs Section 91 vs Section 92
| Provision | Main subject | Core mechanism |
|---|---|---|
| Section 89 | Directors of private company | Specified liability where tax/interest/penalty cannot be recovered from the private company, subject to conditions. |
| Section 90 | Partners of firm | Firm and each partner jointly and severally liable, with special retirement rules. |
| Section 91 | Guardian, trustee or agent of minor/incapacitated person | Tax, interest and penalty levied upon and recoverable from representative carrying on business for the protected person. |
| Section 92 | Court of Wards, Administrator General, Official Trustee, receiver or manager | Special liability where the estate/business is under the control of the specified authority or manager. |
27. Legislative position
Section 91 formed part of the original CGST Act framework and came into force with the Act's substantive provisions from 1 July 2017. The current India Code text continues to contain the same core rule for guardians, trustees and agents carrying on business for minors or other incapacitated persons.
The provision is comparatively short, but its practical importance comes from the fact that it connects a representative's management of the business with the normal GST tax, interest, penalty, assessment and recovery machinery.
