Casual taxable person and non resident taxable person registration

Two short term registrations for people doing business in a state where they have no presence.

The mechanics

Application at least five days before commencement of business, with the estimated tax liability deposited in advance.

Validity for the period specified in the application, up to ninety days, extendable by a further period not exceeding ninety days on an application with an additional deposit.

The advance deposit is credited to the electronic cash ledger and used against the liability, with the balance refundable after the returns for the period are filed.

For a non resident taxable person, the return and credit position differ, and credit entitlement is restricted, which must be factored into pricing.

Where these registrations are used

Exhibitions, trade fairs and seasonal events, where goods are sold in a state for a short period.

Short term project execution where a full registration is disproportionate and no fixed place of business exists.

Foreign suppliers undertaking a one off supply in India.

In each case the alternative is a full registration, which may be simpler where the activity is likely to recur, since the casual registration cannot be extended indefinitely.

The practical decisions

Estimate the liability carefully. Under estimating produces a shortfall and a payment difficulty mid event; over estimating locks up cash until the refund.

Diarise the validity date and the extension application; supplies after expiry are supplies by an unregistered person.

File the return and claim the balance of the advance deposit promptly; these refunds are commonly abandoned.

Where the activity recurs annually, compare the cost of repeated casual registrations against a regular registration with an additional place of business.
