Introduction

SECTION 5. INTEREST IMPOSED

Internal Revenue Bulletin 2006-46 · 2026-10-03 edition · updated 2026-10-04 · United States

WHEN NO TAX DUE

Treas. Reg. § 1.1441–1(b)(7)(iii) provides that a withholding agent that has failed to withhold tax other than based on reliance on the appropriate presumptions is not relieved from liability for interest under section 6601. It further provides that such liability exists even when there is no underlying tax that is ultimately shown to be due. That is, the regulation imposes an interest charge under section 6601 on a withholding agent for an amount of tax that has not in fact been imposed. Treas. Reg. § 1.1441–1(b)(7)(v) sets forth two examples that illustrate the operation of this rule.

The IRS and Treasury intend to issue regulations retroactive to January 1, 2001, removing the rule in Treas. Reg. § 1.1441–1(b)(7)(iii), and the accompanying examples illustrating the rule in Treas. Reg. § 1.1441–1(b)(7)(v), that imposes interest under section 6601 when no underlying tax liability is imposed. Further, the IRS and Treasury intend, in the new regulations, to clarify also that, like interest, penalties that are computed based on underpayments of tax will not be imposed when no tax has in fact been imposed. Taxpayers may rely on this notice until the regulations removing the rule are finalized.
