Rebate under section 87A: new regime increases rebate and raises the income threshold compared with the old regime. Rebate under section 87A differentiates the old and new individual tax regimes by income threshold and maximum rebate. The old regime grants a full rebate for resident individuals below a lower income threshold up to a capped amount; the new regime increases the qualifying income threshold and raises the maximum rebate, with the rebate limited to the taxpayer's actual income tax liability.
