Paragraph-wise decode
Creates the complete invoice-timing architecture for goods, services, continuous supplies, RCM recipient invoices, revised invoices, small-value supplies and special documents. Goods invoice: before/at removal where movement occurs, otherwise before/at delivery or availability. Service invoice: before or after supply but within the prescribed period. Special documents include revised invoice, bill of supply, receipt/refund/payment voucher and recipient-issued RCM invoice.

Continuous supply and sale-on-approval transactions have separate statutory timing.
Section-Rule-Form-Notification bridge
The mapping is a legal concordance, not a round-robin related-link list. It is limited to instruments certified in this phase.
Practical example
Goods leave the supplier on 12 July and reach the customer on 15 July. The tax invoice must ordinarily exist by removal on 12 July, not on delivery.
Professional alert
Invoice timing drives tax period, interest, e- invoice validity, recipient ITC and penalty exposure. A portal document created late does not retrospectively cure the statutory breach.
Implementation checklist
- Fix the transaction, taxable period and jurisdiction.
- Read every subsection, proviso, explanation and omission marker.
- Open the mapped Rule, form, notification and circular.
- Test State/UT variation and portal version.
- Preserve evidence, approvals, working papers and acknowledgements.
- Record the conclusion, assumptions, source date and reviewer.
Evidence and retention checklist
- Contract, purchase order, invoice or underlying transaction document.
- Registration, return, ledger, challan and portal acknowledgement.
- Official Act/Rule/notification version used and effective date.
- Internal tax position paper, computation and management approval.
- Correspondence, notices, replies, orders and appeal papers where applicable.
Practical Q&A
- What does section 31 regulate?
- It regulates tax invoice. Read the exact text, conditions, exceptions and transaction date together.
- Which subordinate law should be checked?
- Rule 46, Rule 46A, Rule 47, Rule 47A, Rule 48, Rule 49, Rule 50, Rule 51, Rule 52, Rule 53, Rule 54, Rule 55. Notifications, circulars, forms and the corresponding SGST/UTGST layer may also apply.
- What evidence should be retained?
- Preserve the contract or transaction record, invoice or form, portal acknowledgement, payment/ledger evidence, correspondence, legal working and the official source version used.
- Can portal behaviour override the statute?
- No. Portal functionality is operational evidence; legal entitlement and liability remain controlled by the Act, Rules, notifications and binding decisions.
