Analysis of Section 12 and Section 13 of the CGST Act: Time of Supply of Goods and Services
The liability to payGST Sections 130 vs 73/74: Adjudication vs. Confiscation Analysis GST arises upon the "time of supply". Sections 12 and 13 of the CGST Act separately govern the time of supply for goods and for services, respectively. These provisions establish the specific point of taxation, dictating when tax liability crystallises on a supply.
The liability to pay tax on goods arises at the time of supply, which is the earliest of:
Date of issue of invoice by supplier, or last date on which invoice is required to be issued under Section 31(1)
Date on which the supplier receives payment with respect to the supply.
"Date of receipt of payment" means the earlier of:
Date entered in supplier's books
Date credited in bank account
Event
Time of Supply (Earliest of)
Invoice issued
Date of invoice or last date to issue (u/s 31(1))
Payment received
Date of payment (books or bank, whichever is earlier)
Proviso: For excess payment received up to ₹1,000 over the invoice, the supplier can opt for the invoice date for such excess.
Earliest of:
Date of receipt of goods; OR
Date of payment (as entered in books OR debited in bank, whichever is earlier)
If supply is identifiable at issue: Date of issue of voucher
Other cases: Date of redemption of voucher
Periodical return to be filed: Due date of such return
Other cases: Date of payment of tax
Date on which supplier receives such additional consideration
Invoice is a record—not the event—of sale or supply (see commentary).
Barter, lease, rental, etc., also require consideration for the time of supply, not just the sale.
Provisional entries in the recipient’s books: If the time of supply cannot be determined by clauses (a/b/c), it is the date of such entry in the books of account (commentary).
Liability to pay tax on services arises at the time of supply, which is the earliest of:
Date of issue of invoice (if within prescribed time of Section 31(2)) or date of payment, whichever earlier
If invoice not issued in time: Date of provision of service or payment receipt date, whichever earlier
If neither above applies: Date on which recipient records supply in his books

Timely maintenance of records and strict adherence to invoice/payment timelines is essential.
For vouchers and special charges, note the distinct rules for time of supply.
Reverse charge compliance remains important for ITC and correct payment dates.
Default to recipient’s books/return date only if primary rules fail
New amendments/notifications should always be reviewed for latest compliance requirements
No major changes in core mechanics of Section 12/13 up to June 2024

Section 12 (Goods) and Section 13 (Services) of the CGST Act lay down parallel but distinctly nuanced provisions for determining the time of supply, which is crucial for proper GST compliance.
Adherence to prescribed timelines under these sections is fundamental for correct GST reporting, tax payment, and avoidance of interest and penalties.
Businesses must align accounting practices with these legal requirements and stay alert for any changes via notifications or circulars impacting compliance timelines.
