Tax rebate under the new regime: marginal relief limits rebate where tax exceeds the excess income over threshold. Resident individuals receive a tax rebate under the new consolidated provision mirroring prior law: full tax payable or a capped amount where total income does not exceed prescribed thresholds. A marginal relief mechanism applies when total income slightly exceeds the new-regime threshold; the rebate equals the tax on total income minus the excess of total income over the threshold, subject to the cap and not exceeding tax computed before allowing the rebate. Rebate applies only to residents, is deducted before cess and surcharge, and reduces total tax payable.
