(d) Family and family size-
(1) In general. A taxpayer's family means the individuals for whom a taxpayer properly claims a deduction for a personal exemption under section 151 for the taxable year. Family size means the number of individuals in the family. Family and family size may include individuals who are not subject to or are exempt from the penalty under section 5000A for failing to maintain minimum essential coverage.

For taxable years to which section 151(d)(5) applies, a taxpayer's family means the taxpayer, including both spouses in the case of a joint return, except for individuals who qualify as a dependent of another taxpayer under section 152, and any other individual for whom the taxpayer is allowed a personal exemption deduction and whom the taxpayer properly reports on the taxpayer's income tax return for the taxable year. For purposes of this paragraph (d)(2), an individual is reported on the taxpayer's income tax return if the individual's name and taxpayer identification number (TIN) are listed on the taxpayer's Form 1040 series return. See§ 601.602 of this chapter.
(e) Household income-
(1) In general. Household income means the sum of-
(i) A taxpayer's modified adjusted gross income (including the modified adjusted gross income of a child for whom an election under section 1(g)(7) is made for the taxable year);
(ii) The aggregate modified adjusted gross income of all other individuals who-
(A) Are included in the taxpayer's family under paragraph (d) of this section; and

(i) Amounts excluded from gross income under section 911;

Thus, the Federal poverty line for computing the premium tax credit for a taxable year is the Federal poverty line in effect on the first day of the initial or annual open enrollment period preceding that taxable year. See 45 CFR 155.410. If a taxpayer's primary residence changes during a taxable year from one state to a state with different Federal poverty guidelines or married taxpayers reside in separate states with different Federal poverty guidelines (for example, Alaska or Hawaii and another state), the Federal poverty line that applies for purposes of section 36B and the associated regulations is the higher Federal poverty guideline (resulting in a lower percentage of the Federal poverty line for the taxpayers' household income and family size).
