What is a Casual Taxable Person under GST?

Under Section 2(20) of the CGST Act, 2017, a Casual Taxable Person means a person who has a fixed place of business in one state but undertakes a supply of goods or services in another state - whether as a principal, agent, or in any other capacity - occasionally. The key elements are: (1) the person has a fixed place of business in India, (2) they occasionally supply goods/services in a state where they do not have such a place, (3) the supply is temporary in nature.

The most common scenarios for CTP registration include: event organisers conducting exhibitions or trade shows in states other than their registered state; contractors executing projects in different states; seasonal businesses (e.g., sale of woollen clothing in hill stations during summer); pop-up retail stores; and temporary food stalls or kiosks during festivals or fairs.

Rule 19 of the CGST Rules, 2017 prescribes the procedure for CTP registration. The person must apply in Form GST REG-01, specifying the state(s) where the temporary activity will be conducted and the period for which registration is sought. The proper officer may grant registration for a period not exceeding 90 days from the date of issue. If the person needs an extension, they must apply before the expiry of the 90-day period, and the officer may extend it by another 90 days.

A critical requirement is the advance deposit of tax. Under Rule 19(4), the applicant must deposit an amount equal to the estimated tax liability for the period of registration. This advance deposit is adjusted against the tax liability as per GSTR-3B returns filed for the registration period. If the actual tax liability exceeds the advance deposit, the difference must be paid before filing GSTR-3B. If the advance deposit exceeds the tax paid, the balance is refunded.

Unlike regular taxpayers who can avail ITC on all purchases, CTPs can claim ITC only on inputs used for the specific activity for which they obtained CTP registration. The ITC must be reversed proportionally if the goods/services are used for purposes other than the registered activity.

प्रक्रिया

CTP GST registration process

The registration must be obtained before commencing the temporary business activity. Here is the complete process.

  1. Determine CTP requirement

    Assess whether your activity qualifies as a casual taxable supply. If you have a regular GST registration in your home state and are conducting taxable supplies in another state temporarily, CTP registration is required unless you already have a regular registration in that state.

  2. Calculate estimated tax liability

    Estimate the turnover for the 90-day period and calculate the expected GST liability (CGST + SGST + IGST as applicable). This amount must be deposited as an advance before registration is granted. Over-estimating ties up working capital; under-estimating leads to additional payment during the period.

  3. File Form GST REG-01 on GST portal

    Register on the GST portal (www.gst.gov.in), navigate to Services > Registration > New Registration, and select 'Casual Taxable Person' as the type. Fill in the required details: existing registration (if any), state of temporary activity, period of activity (up to 90 days), estimated turnover, and advance deposit details. Upload supporting documents and submit.

  4. Deposit advance tax

    After submitting the application, deposit the estimated tax liability through the GST portal using the challan generated for CTP. The advance deposit must be made before the application is processed. The GSTIN is generated only after the advance deposit is confirmed.

  5. GSTIN issuance

    The jurisdictional GST officer verifies the application and documents. If everything is in order, the officer grants registration and issues a GSTIN valid for 90 days. The GSTIN for CTP typically starts with a prefix denoting the temporary state. You can check the status on the GST portal.

  6. Conduct business and file returns

    With the CTP GSTIN, you can raise tax invoices, collect tax, and file GSTR-1 and GSTR-3B returns for the registration period. The advance deposit is adjusted against the actual tax liability as per GSTR-3B. Any excess advance is refunded; any shortfall must be paid before filing the next return.

  7. Extension or surrender

    If the activity continues beyond 90 days, apply for an extension before the expiry date on the GST portal. The officer may grant an extension of up to another 90 days. When the activity concludes, file GSTR-3B for the final period and surrender the CTP registration. Any remaining advance deposit balance is refunded.

The advance deposit requirement is often the biggest pain point for CTP applicants. Estimating tax liability 90 days in advance requires accurate revenue forecasting - over-estimate and you tie up working capital; under-estimate and you need to top up mid-activity. We calculate the advance deposit based on your contract value, activity type, and applicable GST rates to get it as close as possible to the actual liability. Also, if you forget to apply for extension before the 90-day expiry, your GSTIN is automatically cancelled and you cannot continue making taxable supplies. Our team tracks the expiry date and files the extension application well in advance.

समय-सीमा

CTP registration timeline

From application to GSTIN issuance, here is the typical timeline.

CTP registration timeline
चरणसमय
Determine CTP requirement and estimate liability1-2 days
Prepare documents and calculate advance deposit2-3 days
File REG-01 application on GST portal1 day
Deposit advance tax via challan1 day
Officer verification and GSTIN issuance3-7 working days
90-day registration period (activity and returns)90 days
Extension application (if needed)3-5 working days before expiry

Simple CTP registrations with clear documentation are typically granted within 3-5 working days. Complex cases with large advance deposits or cross-state verification may take 7-10 days. Plan your activity start date at least 2 weeks after filing the application to account for processing delays. The extension must be applied for before the 90-day expiry - late applications are typically rejected.

फ़ायदे

Why register as a Casual Taxable Person?

Legal compliance

  • CTP registration is mandatory under Section 24(vii) for casual taxable supplies - operating without registration exposes you to penalties up to INR 10,000 or the tax amount evaded, whichever is higher(Section 122 - Penalties)
  • A valid CTP GSTIN allows you to raise valid tax invoices, collect GST from customers, and claim ITC on your purchases - without it, your business transactions are legally impaired

Input Tax Credit

  • As a CTP, you can claim ITC on inputs used exclusively for the registered activity - this can significantly reduce your effective tax cost for the temporary operation(Section 16 - ITC provisions)
  • ITC claimed during the CTP period can be carried forward or adjusted, subject to the condition that it is used only for the registered activity

Flexible validity

  • The 90-day initial validity covers most events and seasonal operations. The 90-day extension option provides flexibility for longer-duration projects or events(Rule 19 - CTP procedure)
  • Multiple CTP registrations can be obtained in different states for concurrent activities - each state requires a separate CTP registration

Business continuity

  • With CTP registration, you can continue your regular business in your home state under your regular GSTIN while simultaneously operating the temporary activity under the CTP GSTIN - both registrations coexist without conflict

अक्सर होने वाली गलतियाँ

Common CTP registration mistakes

Starting activity without CTP registration

Section 24(vii) mandates registration before commencing supply. Starting without registration attracts a penalty of INR 10,000 or the tax amount evaded. Apply at least 10-15 working days before the activity starts.

Under-estimating advance deposit

The advance deposit must cover your estimated tax liability. If actual liability exceeds the deposit, you must pay the difference before filing GSTR-3B. We calculate the deposit based on your contract value and applicable GST rates.

Missing extension deadline

CTP registration lapses automatically after 90 days. Apply for extension at least 7 days before expiry. Late applications are typically rejected, forcing you to re-register.

Confusing CTP with regular multi-state registration

CTP is for temporary activities. If you have regular, ongoing business in a state, apply for regular GST registration in that state instead of repeatedly using CTP.

Not filing returns during CTP period

CTP registrants must file GSTR-1 and GSTR-3B just like regular taxpayers. Non-filing attracts late fees (INR 50/day for tax-paying months) and can lead to GSTIN cancellation.

Using CTP GSTIN for non-registered activities

ITC under CTP is restricted to the registered activity. Using the CTP GSTIN for unrelated activities can result in ITC reversal and penalties.
