26 CFR § 1.6015-2 - Relief from liability applicable to all qualifying joint filers.
(a) In general. A requesting spouse may be relieved of joint and several liability for tax (including additions to tax, penalties, and interest) from an understatement for a taxable year under this section if the requesting spouse elects the application of this section in accordance with §§ 1.6015-1(h)(5) and 1.6015-5, and -
(1) A joint return was filed for the taxable year;
(2) On the return there is an understatement attributable to erroneous items of the nonrequesting spouse;
(3) The requesting spouse establishes that in signing the return he or she did not know and had no reason to know of the understatement; and
(4) It is inequitable to hold the requesting spouse liable for the deficiency attributable to the understatement.
(b) Understatement. The term understatement has the meaning given to such term by section 6662(d)(2)(A) and the regulations thereunder.
(c) Knowledge or reason to know. A requesting spouse has knowledge or reason to know of an understatement if he or she actually knew of the understatement, or if a reasonable person in similar circumstances would have known of the understatement. For rules relating to a requesting spouse's actual knowledge, see § 1.6015-3(c)(2). All of the facts and circumstances are considered in determining whether a requesting spouse had reason to know of an understatement. The facts and circumstances that are considered include, but are not limited to, the nature of the erroneous item and the amount of the erroneous item relative to other items; the couple's financial situation; the requesting spouse's educational background and business experience; the extent of the requesting spouse's participation in the activity that resulted in the erroneous item; whether the requesting spouse failed to inquire, at or before the time the return was signed, about items on the return or omitted from the return that a reasonable person would question; and whether the erroneous item represented a departure from a recurring pattern reflected in prior years' returns (e.g., omitted income from an investment regularly reported on prior years' returns).
(d) Inequity. All of the facts and circumstances are considered in determining whether it is inequitable to hold a requesting spouse jointly and severally liable for an understatement. One relevant factor for this purpose is whether the requesting spouse significantly benefitted, directly or indirectly, from the understatement. A significant benefit is any benefit in excess of normal support. Evidence of direct or indirect benefit may consist of transfers of property or rights to property, including transfers that may be received several years after the year of the understatement. Thus, for example, if a requesting spouse receives property (including life insurance proceeds) from the nonrequesting spouse that is beyond normal support and traceable to items omitted from gross income that are attributable to the nonrequesting spouse, the requesting spouse will be considered to have received significant benefit from those items. Other factors that may also be taken into account, if the situation warrants, include the fact that the requesting spouse has been deserted by the nonrequesting spouse, the fact that the spouses have been divorced or separated, or that the requesting spouse received benefit on the return from the understatement. For guidance concerning the criteria to be used in determining whether it is inequitable to hold a requesting spouse jointly and severally liable under this section, see Rev. Proc. 2000-15 (2000-1 C.B. 447), or other guidance published by the Treasury and IRS (see § 601.601(d)(2) of this chapter).
(e) Partial relief -
(1) In general. If a requesting spouse had no knowledge or reason to know of only a portion of an erroneous item, the requesting spouse may be relieved of the liability attributable to that portion of that item, if all other requirements are met with respect to that portion.
