Introduction
Outward-supply reporting is the supplier-side record of taxable supplies. It feeds the recipient information system under section 38 and is separate from the tax return under section 39.
Key takeaways
Who files
The ordinary registered supplier files, while Input Service Distributors, non-resident taxable persons and persons paying under sections 10, 51 or 52 are excluded from this section.
What is reported
Details include invoices, debit notes, credit notes and revised invoices relating to the tax period. Form and current filing date depend on the Rules and applicable notifications.
Corrections
An error or omission may be rectified in the prescribed manner, with tax and interest where short payment resulted. The ordinary cutoff is 30 November after the financial year or actual furnishing of the relevant annual return, whichever is earlier.
Filing sequence and outer limit
Earlier outward-supply details generally must be filed before later periods. A three-year outer filing bar applies, subject to a notified relaxation for a person or class.

Practical checklist
Do
- Reconcile invoice and credit-note registers to outward-supply details.
- Check the current portal date and any extension notification for the taxpayer class.
- Track the financial-year rectification cutoff and previous-period filing status.
Avoid
- Rely on an old portal deadline without checking current Rules and notifications.
Frequently asked questions
Is the tenth day in the Act always the live filing deadline?
No. Section 37 itself allows notified extensions and prescribes form and manner. Check the current Rules and notifications for the relevant period and taxpayer class.
