(2) Losses: General Rule. If the losses from the sale or exchange of capital assets exceed the net gains from the sales, so a loss is reported on Form 1040, then, subject to the limitation provided for in Internal Revenue Code (IRC) Section 1211, allocate the excess to the spouse responsible for the excess. (For examples 1-3 below, the Section 1211 limitation is $3,000.) If both spouses are responsible for the excess, then allocate the excess, subject to IRC Section 1211 limitation, between the spouses on a pro rata basis.
Missouri Answer: The amount of the excess is $5,000 but, because of the limitation of IRC Section 1211, the deductibility of the loss is limited to $3,000. Since both spouses are responsible for the excess, then allocate the $3,000 on a pro rata basis, that is—Spouse 1 (2/5 x 3,000) and Spouse 2 (3/5 x 3,000).
MAGI is therefore— Spouse 1 Wages $10,000 Section 1211 deduction ($1,200) MAGI $8,800
MAGI is therefore— Spouse 1 Wages $10,000 Section 1211 deduction ($2,850) MAGI $7,150
(C) Example No. 3: Assume the following facts on the joint federal income tax return for 2017: Spouse 1 Wages $10,000 Short-term Gain (loss) $1,000 Long-term Gain (loss) ($8,000) Section 1211 limitation FAGI Missouri Answer: Since there are no net short-term losses, all of the IRC Section 1211 limitation of $3,000 should be allocated from excess long-term losses. Since Spouse 1 is responsible for the excess, the entire amount of the limitation is allocated to Spouse 1. $15,000 ($5,000)
