It is granted to heirs and, where applicable, to cohabitants liable for payment of the persons mentioned in 1° to 2° ter and 7° to 10° of I of l’article 796 :
1°(Repealed);
2° For income tax, a discharge of payment equal to the income tax contributions and other taxes appearing on the same article of roll remaining due on the date of death or due, in respect of the taxation of income received or realised by the deceased. This discharge cannot cover taxes due on income relating to years prior to that preceding the year of death. The sums paid before the death in application of articles 1664 and 1681 A, in respect of the deceased’s income, are not refunded. The heirs are exempt from declaring the income mentioned in the first sentence of this 2°.
The heirs may waive the benefit of the provisions set out in 2° and opt for the rules of ordinary law relating to the declaration of income and the assessment of tax. In the event that the amount of tax due in respect of income received or earned by the deceased is less than the amount of deductions and advance payments made prior to the death in respect of the same income, the difference is refunded. Otherwise, the option may be revoked.
