Contrary to what intuition might indicate, being able to claim someone as a dependent on a federal income tax return doesn’t always offer advantageous tax consequences. It’s understandable that people would think that the reduction in taxable income generated by the dependency exemption deduction reduces taxes. Usually it does. But sometimes, strange things happen.
A cautionary example of this unexpected consequence was provided recently by the United States Tax Court in
Gibson v. Comr., T.C. Memo 2017-187. The taxpayers filed a joint return for 2014. During 2014 and 2015, their adult son did not live with them. He held a job, and at some point during 2014, the son used an address in another town, an address that was not the taxpayers’ address. For 11 months during 2014, the son obtained health insurance from Human Employers Health Plan of Georgia, which the son obtained though an application with the Health Insurance Marketplace. Humana collected premiums of $4,628.80, which were paid through the mechanism of advance payments of the premium assistance tax credit under section 36B. Monthly invoices for September through December of 2014 sent to the son at his separate address showed a gross monthly premium of $420.80, an offsetting Advance Premium Tax Credit of $420.80, and a balance due of zero. In mid-January of 2015, Form 1095-A was sent to the son at his separate address, showing the advance payments of the premium assistance tax credit that had been made to Humana in 2014. On January 1, 2015, the son enrolled in a Blue Cross Blue Shield plan offered by his employer.
On their 2014 joint income tax return, the taxpayers claimed their son as a dependent. The IRS did not dispute the son’s status as a dependent. The taxpayers claimed a refund of $6,880 on the return, reflecting the excess of the tax withheld from their reported income over the tax reported due. They did not report the advance payments of the premium assistance tax credit on their return. When they filed their return they were not aware that the son had obtained the Humana policy or that the advance payments had been made to Humana in 2014 for the son’s policy.
The IRS determined that the taxpayers tax should be increased to reflect the advance payments of the premium assistance tax credit to Humana on the son’s behalf during 2014. This caused a deficiency of tax that reduced the taxpayers’ claimed refund by $4,628.80.
As the Tax Court explained, section 36B permits eligible taxpayers, those with household incomes between 100 percent and 400 percent of the Federal poverty line, to claim the premium assistance tax credit for health insurance covering dependents, and dependents may not claim the credit on their own returns. Though advance payments of the premium assistance tax credit are made directly to the insurer during the taxable year, advance payments of the premium assistance tax credit made on behalf of a taxpayer or members of the taxpayer’s household, including dependent children, must be reported on the taxpayer’s federal income tax return. If the advance payments exceed the premium assistance tax credit to which the taxpayer is entitled, the excess increases the tax owed by the taxpayer and reduces any refund otherwise payable.
Because their income exceeded 400 percent of the federal poverty line, the taxpayers were not entitled to any amount of premium assistance tax credit. The entire amount of the advance payments of the premium assistance tax credit on their son’s behalf paid to Humana by the Health Insurance Marketplace during 2014 increased the taxpayers’ tax owed and reduced their claimed refund. It was on this basis that the IRS determined a deficiency and reduced the claimed refund.
The taxpayers did not deny that their reported income level made them ineligible for the premium assistance tax credit. They disagreed that their son received insurance from Humana, and therefore they disagreed whether any advance payments of the premium assistance tax credit were made to Humana on their son’s behalf. The son, unable to testify at the trial, provided a signed affidavit in which he claimed that he had only employer-provided Blue Cross insurance and that he did not receive a Form 1095-A showing advance payments of the premium assistance tax credit on his behalf to Humana. The Tax Court, however, pointed out that the reliable evidence presented to it established that the son’s recollection about his insurance coverage was “mistaken.” That evidence included business records from the son’s employer, from Humana, and from the Health Insurance Marketplace. It established that the son’s Blue Cross coverage did not begin until 2015, that he was covered by the Humana policy in 2014, and that Humana received advance payments of premium assistance tax credits to offset the son’s insurance premiums.
The court pointed out that it did not doubt the taxpayers’ testimony that they believed that their son did not have an insurance policy from Humana. The fact that their son did not live with the taxpayers led the court to conclude that it believed their testimony that they were unaware of the insurance coverage and any confirming information that was mailed to him. Thus, because the taxpayers did not dispute that their reported income level made them ineligible for the premium assistance tax credit, their tax was increased, and their refund reduced, by the amounts prepaid to Humana on their son’s behalf during 2014.
The dependency exemption deduction for 2014 was $3,950. Although the taxpayers’ adjusted gross income and taxable income was not provided by the opinion, at best it saved them roughly $1,600 in tax liability. The price that they paid was $4,628.80. Would it not have been better to not claim the son as a dependent? If the taxpayers were entitled to claim their son as a dependent, which the facts suggest was the case, then failure to do so would not permit the son to claim the credit because the credit is denied to any individual with respect to whom a dependency exemption deduction is allowable to another taxpayer. But would failure to claim the son as a dependent, even though he qualifies as a dependent, eliminate the requirement that the advance premium payments made on his behalf be added to the taxpayers’ tax? I cannot find anything definitive that answers the question. If the answer is no, then failure to claim the son as a dependent, even though he qualifies, would be counterproductive. If the answer is yes, it still might not make sense to fail to claim the son as a dependent. Why? The son, not entitled to the credit because he could be claimed as a dependent, would be the one required to add the advance payments to his tax. Perhaps someone who has expertise in the intersection of tax law and health insurance law can share some insights.
