Advance tax in GST is applicable to Non Resident Taxable Person and Casual Taxable Person.
NRTP and CTP are the persons who are not in regular business transactions at one place.
Their business activities are either occasional or seasonal or their place is not fixed.
They have to apply for a temporary registration.
Along with registration, the advance GST deposit is required to be made, which shall be credited to cash ledger. And later on, at the time of return filing, this shall be adjusted against the actual GST liability.
