Deductibility rule expanded to include prescribed electronic payment modes, allowing additional electronic channels for tax deduction eligibility. The Bill expands deductible payment modes by replacing 'bank account' references with 'bank account or through such other electronic mode as may be prescribed' and adds identical language to the subsection addressing cheques, drafts and electronic clearing; it empowers the Board to prescribe qualifying electronic modes so that payments by those modes will be permitted for deduction in lieu of the previously required account-payee cheque, bank draft or bank-account electronic clearing.
