Reconcile the example
- 30,00,000 − 24,00,000 = 6,00,000.
Approval is sought, not granted; category eligibility still requires the prescribed authority’s decision.
Prepare, furnish and retain
- Use the form identity and period above, then determine the person who prepares, issues or verifies it from Rule 32, Rule 35. An authority-issued order is not an applicant filing.
- Collect the records that support the actual fields in the example; keep any mandatory schedules and annexures specified in the complete source form.
- Reconcile dates, amounts, units and identifiers to the underlying records. Preserve the applicable rule version and any later correcting notification.
- Where the rule prescribes electronic furnishing, use the current official utility/schema and authorised verification. A local PDF does not produce a portal acknowledgement.
- Retain the submitted version, supporting schedules and actual acknowledgement or issued certificate/order, as applicable. This fictional model supplies none of those evidential outcomes.

Questions readers ask
Does this sample prove approval, filing or a professional conclusion?
No. It completes the named fields using synthetic facts. It has no real signature, DSC, approval or acknowledgement.
Can I use the legacy form number for a current tax-year obligation?
Establish the governing period first. A predecessor number is a cross-reference; earlier-year procedures and current-year forms must be kept distinct.
