To amend the Internal Revenue Code of 1986 to establish the individual tariff refund credit.

HR 7636 creates a new tax credit for individuals affected by unlawfully imposed tariffs. It allows eligible individuals (excluding non-residents, those with dependents claimed by others, and estates/trusts) to receive a refundable credit equal to their household's share of total tariff revenues repaid by the government after a court orders repayment of unlawfully collected tariffs (imposed after January 20, 2025). The credit amount is calculated by dividing total repaid tariff revenues by the number of eligible households, with household size including the individual plus dependents. The credit applies to taxable years ending before the court order date, with refunds processed rapidly and without interest. A separate provision also imposes a 100% excise tax on corporate tariff refunds not passed to consumers.
