Notice 2026-3, page 307.

Notice 2026-3 provides relief from the additions to tax under sections 6654 and 6655 for underpayment of estimated income tax, and assists in implementing section 70437 of the One, Big, Beautiful Bill Act, which added a new limited payment deferral election in section 1062(a) applicable in the case of a sale or exchange of qualified farmland property to a qualified farmer (qualified sale or exchange). In the interest of sound tax administration, the IRS will waive a portion of the addition to tax under sections 6654 and 6655 attributable to a qualified sale or exchange for which an election under section 1062(a) (section 1062 election) is properly made. The amount of the relief depends on the amount of tax the payment of which is deferred by the section 1062 election.
