Introduction
The computational mechanisms under GST explain how GST is calculated and paid in different business situations. They help students understand that GST is not always collected and deposited by the supplier in the same way.
Understanding these mechanisms is essential for solving GST-based numerical problems, identifying the correct taxpayer, and answering board examination questions on indirect taxation.
Composition Scheme Under GST
Eligibility: Businesses whose annual turnover in the previous financial year is less than ₹1.5 crore can opt for the composition scheme.
Rules for Composition Dealers
-
No Tax Collection: Dealers cannot collect tax from customers; they must issue a 'Bill of Supply' instead of a tax invoice.
-
Mandatory Text on Bill: Must print "Composition taxable person not eligible to collect tax on supplies" in bold letters on the bill.
-
Shop Signboard: The shop signboard must display "Composition taxable person".
-
Filing Returns: Returns must be filed quarterly (every 3 months).
-
Inter-state Sales Not Allowed: Cannot sell goods outside the state (though purchases from other states are allowed).
-
No ITC Benefit: Dealers cannot avail the benefit of Input Tax Credit (ITC).
