Casual Taxable Person under GST: Registration Traps for Exhibitions and Trade Fairs

A casual taxable person under GST must take registration when it makes taxable supplies at an exhibition or trade fair in a State where it has no fixed place of business. This rule applies to outstation sellers, pop-up stalls and event participants. Threshold exemption does not protect such taxable supplies and advance tax deposit becomes a key compliance step.

Meaning of Casual Taxable Person under GST

Section 2(20) of the CGST Act defines a casual taxable person as a person who undertakes event-based transactions involving supply of goods or services in the course or furtherance of business, in a State or Union Territory where he has no fixed place of business.

This definition covers a supplier acting as principal, agent or in any other capacity.

A business becomes a casual taxable person under GST when these conditions exist:

• it makes taxable supplies;
• it enters another State or Union Territory for business;
• it has no fixed place of business in that State or Union Territory;
• the activity is linked to business.

This rule has direct relevance for exhibitions, trade fairs, buyer-seller meets, product expos, food festivals, jewellery shows, fashion exhibitions, handloom fairs and pop-up sale events.

Why Exhibitions and Trade Fairs Create GST Risk

Exhibitions create GST risk because the seller leaves its registered State and makes taxable supplies from another State.

For example, a jeweller registered in Mumbai participates in an exhibition-cum-sale in Delhi. The jeweller has no fixed place of business in Delhi. If the jeweller sells ornaments from the Delhi stall, the jeweller requires casual taxable person registration in Delhi.

The existing Maharashtra GST registration does not cover counter sales made from Delhi. The Delhi event creates a separate registration requirement because the taxable supply takes place in a State where the jeweller has no fixed place of business.

This is the main registration trap. Businesses focus on event booking, stall design, product movement and sales targets. GST registration planning gets missed until the event starts.

Threshold Exemption Does Not Apply

Section 24(ii) of the CGST Act requires compulsory registration for casual taxable persons making taxable supply.

This means the normal threshold exemption under Section 22 does not protect such suppliers. A small seller making limited taxable sales at a trade fair still needs registration if the facts satisfy the casual taxable person test.

A home decor seller from Jaipur attending a three-day exhibition in Bengaluru must review casual taxable person registration before the event. The size of expected sales does not remove the Section 24 requirement where taxable supply is made from the Bengaluru stall.

Registration Must Be Taken Before Business Starts

Section 25 requires a casual taxable person to apply for GST registration at least five days before commencement of business.

For exhibitions, the business should complete GST planning before goods are moved to the venue. The registration application should match the event documents.

The following records should be kept ready:

• stall allotment letter;
• event agreement;
• venue address;
• period of exhibition;
• details of goods or services;
• estimated turnover;
• estimated tax liability;
• authorised signatory details;
• bank details.

A late registration creates invoice issues. It also creates risk in return filing, e-way bill records, input tax credit and buyer reporting.

Advance Tax Deposit is Mandatory

Section 27 of the CGST Act requires a casual taxable person to deposit advance tax equal to the estimated tax liability for the registration period.

This advance tax is credited to the electronic cash ledger. The supplier uses it for payment of GST on taxable supplies made during the exhibition or trade fair.

The estimate must be prepared with care. If the estimate is too low, the supplier faces short payment and interest risk. If the estimate is too high, funds remain blocked until refund or adjustment is handled under GST.

CBIC Circular No. 71/45/2018-GST clarifies that the advance deposit is linked to estimated net tax liability after considering eligible input tax credit. This helps exhibitors who incur GST on venue rent, stall fabrication, transport, local services and event support.

Registration Validity is Limited

A casual taxable person registration has limited validity.

Under Section 27, the registration remains valid for the period mentioned in the application or 90 days from the effective date of registration, whichever is earlier.

The proper officer is permitted to extend the validity for a further period not exceeding 90 days. For extension, the taxpayer must file the required application before expiry and deposit additional estimated tax.

This matters for exhibitions that get extended. It also matters for multi-city event plans, seasonal counters and long promotional stalls.

Exhibition Beyond 180 Days Requires a Different Approach

CBIC Circular No. 71/45/2018-GST also deals with long exhibitions.

If an exhibition lasts beyond 180 days, the person is not treated as a casual taxable person. In such cases, the person must obtain normal registration in that State. After the exhibition ends, the person must surrender the registration.

This rule is important for brands that operate long-term pop-up stores, seasonal counters, or extended display-cum-sale outlets. Such arrangements do not fit the short-term casual taxable person structure.

The correct registration depends on the event period, contract terms, possession of premises, sales model and nature of business activity.

Display of Goods is Not the Same as Local Sale

A business does not become a casual taxable person under GST merely because it displays goods in another State. The key question is whether taxable supply is made from the event location.

If goods are displayed at an exhibition and orders are booked for later supply from the registered place of business, the tax position depends on documents, contract terms, delivery terms and invoice flow. If goods are handed over at the stall against payment, the position is different. That is a local taxable supply from the exhibition State, and casual taxable person registration becomes relevant.

The seller must maintain clean records. Delivery challans, e-way bills, stock records, sales invoices, payment receipts, and order forms must support the adopted GST position.

Input Tax Credit Planning for Exhibitors

Casual taxable person registration also affects input tax credit. An exhibitor incurs GST on several event expenses, including venue rent, stall fabrication, display material, local advertising, manpower services and logistics.

If the exhibitor takes casual taxable person registration in the host State, eligible input tax credit linked to that registration is claimed subject to Section 16 and other GST conditions. This helps reduce the net tax outflow. It also aligns local expenses with local taxable supplies.

Common Registration Traps

Exhibitors should avoid these GST errors:

• attending an outstation trade fair without checking Section 24;
• assuming turnover threshold protects event sales;
• issuing invoices from the home State for sales made at the venue;
• missing the five-day registration timeline;
• underestimating advance tax;
• continuing sales after registration expiry;
• treating a long exhibition as casual business;
• failing to match e-way bills, stock movement, and sales invoices.

Each mistake creates an audit trail. GST officers examine the venue contract, transport records, invoices, payments, returns and buyer details.

Conclusion

Casual taxable person under GST is a core compliance issue for exhibitions and trade fairs. A seller making taxable supplies in another State without a fixed place of business must obtain registration under Section 24, apply before the event, and deposit advance tax under Section 27.

The safest approach is to decide the GST position before booking the stall. If there is sale from the venue, casual taxable person registration must be taken. If the event is for display or order booking, documents must prove that no taxable supply took place at the venue.
