No provision-specific Rule/Form is independently mapped in this tranche. General return, procedure and evidence rules can still apply.

Worked application

A new eligible unit begins producing biogas from biodegradable waste in 2026-27. Its five-year period begins that year if the statutory business conditions are satisfied.

Evidence / compliance checklist

  • Maintain the original eligibility file for section 145, including commencement/approval history and the remaining deduction period.
  • Keep unit-wise books and a computation linking eligible profits to the qualifying undertaking or activity (section 145: Deduction for businesses engaged in collecting and processing of bio-degradable waste).
  • Where Rule 66 applies, obtain Form 32 and reconcile the accountant-certified figures to the return before the due date (section 145: Deduction for businesses engaged in collecting and processing of bio-degradable waste).
  • Preserve evidence that reconstruction, transfer, location, approval and other formation conditions continue to be satisfied (section 145: Deduction for businesses engaged in collecting and processing of bio-degradable waste).

Common mistake

Treating section 145 as a fresh 2026 tax holiday. For section 145, the preserved or transitional old-law eligibility must be checked specifically; the deduction clock does not restart merely because the 2025 Act is now in force.

Recommended approach

For section 145, fix the governing tax year, identify the operative sub-section for “Deduction for businesses engaged in collecting and processing of bio-degradable waste”, trace every amount to evidence, apply only verified Rule/Form links, and retain a computation that another reviewer can reproduce from the primary source.

Thresholds, periods and timing checkpoints

Judicial / interpretive bridge

No section-specific Supreme Court bridge is included for section 145 unless text-equivalence with the 2025 Act has been checked. Legacy cases should not be transplanted into section 145 merely because the subject is similar.
