Year-End Marital Status: Single, Head of Household, or MFS

Answer B. Priya was married on December 31, so she cannot file as single. Because she will not file a joint return, her filing status defaults to married filing separately unless she qualifies to be treated as unmarried for head-of-household (HOH) purposes. The "considered unmarried" HOH rule also requires that a qualifying child live with the taxpayer for more than half the year; Priya has no such child, so she cannot use HOH even though her mother is a dependent.

Why not A: Tempting because a dependent parent can be a qualifying person for HOH when the taxpayer is unmarried. However, a married person must first satisfy the "considered unmarried" rule to use HOH, and that rule requires a qualifying child who lived with the taxpayer for more than half the year, Priya does not meet that requirement.

Why not C: This is tempting because the spouse moved out and the divorce was finalized early next year, but filing status is determined on December 31. Priya was still legally married on that date, so she cannot file as single.

Why not D: Choosing HOH while declining to claim a dependent parent is inconsistent with the facts: Priya cannot use HOH because she fails the "considered unmarried" rule, and the facts otherwise support claiming her mother as a dependent.

Answer B. Morgan was legally married on December 31, so Single is not available (and married filing jointly is precluded by the facts). A married taxpayer can file Head of Household only if treated as unmarried on December 31, the spouse must not have lived in the taxpayer's home during the last six months of the year (July 1-Dec 31); because the spouse lived with Morgan through July 14, Morgan fails the considered-unmarried test. The spouse is alive, so qualifying surviving spouse is not available; therefore Married filing separately is the appropriate status.

Why not A: This distractor tempts candidates who equate the midyear move with being unmarried. However, Single requires being unmarried on December 31; Morgan was legally married on that date, so Single is not permitted.

Why not C: This is the most attractive distractor because Morgan has a qualifying child at home and also pays >50% of the cost of a separate household for a dependent parent (both can be qualifying persons for HOH). The trap is the 'considered unmarried' rule: a married taxpayer may file HOH only if the spouse did not live in the taxpayer's home during the last six months (July 1-Dec 31); the spouse lived there through July 14, so Morgan fails that test.

Why not D: This may lure candidates who focus on the dependent child, but qualifying surviving spouse requires the taxpayer's spouse to have died in one of the two preceding years (and other conditions). Here the spouse is alive, so QSS is not available.

Answer D. Avery remained married at year-end and the couple will not file a joint return, so Single and Married filing jointly are not available. To use Head of Household while married, Avery must meet the 'considered unmarried' rules (file separate returns, pay >50% of household costs, spouse not living in the home during the last 6 months, and the home must be the main home for more than half the year of the taxpayer's child, stepchild, or eligible foster child whom the taxpayer can claim). A niece does not satisfy that specific child/stepchild/foster-child gateway, and a dependent parent living elsewhere likewise does not meet that considered-unmarried requirement. Therefore Avery's available filing status is Married filing separately (see IRS Pub. 501).

Why not A: Tempting because the spouse lived away for the last six months, Avery paid more than half the household costs, and a dependent lived in the home all year; however, the 'considered unmarried' exception for married taxpayers requires the qualifying person to be the taxpayer's child, stepchild, or eligible foster child (a niece does not meet that specific gateway).

Why not B: Tempting because married taxpayers commonly file jointly, but the fact pattern explicitly states Avery and the spouse will not file a joint return, so Married filing jointly is not available.

Why not C: Tempting because the spouse moved out midyear, but legal marital status on the last day of the tax year controls Single status; Avery remained married on the last day of the year and therefore cannot file as Single.

Answer C. Mara satisfies the 'considered unmarried' head-of-household tests (spouse not a member of the household for the last 6 months, not filing jointly) and she paid more than half the cost of keeping up the home where the qualifying child lived. A custodial parent's release of the dependency exemption on Form 8332 does not, by itself, prevent the custodial parent from using the child as a qualifying person for head of household. Given these facts, Mara may file as head of household (see IRS Pub. 501 and Form 8332 instructions for related guidance).

Why not A: This is tempting because assigning the dependency exemption seems controlling, but releasing the exemption under Form 8332 does not remove the child's status as a qualifying person for HOH if the custodial parent meets the other HOH requirements.

Why not B: This confuses legal filing status with the 'considered unmarried' HOH test; a taxpayer who is legally married at year-end generally cannot file as single, if the considered-unmarried tests are met, HOH (not single) is the correct status.

Why not D: This distractor conflates who actually claims the dependency with the custodial parent's HOH qualification; whether Lee claims the child does not, by itself, prevent Mara from qualifying for HOH if she meets the HOH tests.

Answer B. A married taxpayer can qualify for head of household if treated as unmarried at year-end (for example, the spouse was not a member of the household during the last 6 months), no joint return is filed, the taxpayer paid more than half the cost of keeping up the home, and a qualifying child lived there for more than half the year. Dana meets those requirements. For HOH purposes the custodial parent remains the qualifying person even if that parent signs Form 8332 allowing the noncustodial parent to claim the child as a dependent.

Why not A: Tempting because of the lived-apart language, but 'treated as unmarried' for HOH is not the same as being 'single' for filing-status purposes; a legally married taxpayer cannot file as single unless unmarried on the last day of the year.

Why not C: Marital status is generally determined at year-end, but there is a specific exception that allows a married taxpayer to be treated as unmarried for HOH if the treated-as-unmarried tests are met; thus MFS is not the only permissible status.

Why not D: This distractor plays on the assumption that the dependency claim controls HOH status. Under the separated-parents rule the custodial parent can still use the child as the qualifying person for HOH even after releasing the dependency claim on Form 8332.

Answer A. In Year 1 Parker qualifies as 'considered unmarried' for head-of-household purposes because the spouse did not live in Parker's home during the last 6 months of the year, Parker paid more than half the cost of maintaining the home, and the qualifying child lived with Parker for more than half the year; the stem also states Parker does not file a joint return. In Year 2 the divorce was final before year-end, so Parker was unmarried on December 31 and again met the home-maintenance and qualifying-child tests. Therefore, Parker may use head-of-household in both years.

Why not B: This is tempting if a candidate correctly applies the considered-unmarried rule for Year 1 but then incorrectly assumes that a divorced taxpayer in Year 2 cannot claim HOH; because Parker's divorce was final before year-end and the other tests are met, Parker also qualifies in Year 2.

Why not C: This is tempting if a candidate focuses only on marital status at the end of Year 2 and overlooks the considered-unmarried rule that allows a still-married taxpayer to claim HOH for Year 1 when the spouse did not live in the home during the last 6 months and the other requirements are satisfied.

Why not D: This choice reflects the mistaken belief that any marriage during the year or any divorce prevents HOH; in these facts Parker satisfies the HOH tests in Year 1 under the considered-unmarried rule and in Year 2 as an unmarried taxpayer.

Answer A. A married taxpayer can be treated as unmarried for head-of-household purposes if the spouse did not live in the taxpayer's home during the last six months of the year, the taxpayer did not file a joint return, paid more than half the cost of keeping up the home, and the home was the child's principal residence for more than half the year. Those conditions are met here, so Jamie qualifies for head of household.

Why not B: This is tempting because filing status is usually based on marital status at year-end, but the head-of-household rules include a treated-as-unmarried exception that applies when the specified conditions are satisfied.

Why not C: Although living apart is relevant, a legally married person is not 'single' for tax filing status unless divorced or legally separated by year-end; here the correct path is treated-as-unmarried for head of household, not filing as single.

Why not D: A child's age (under 13) is irrelevant to head-of-household eligibility; the governing factors are the treated-as-unmarried criteria and that the taxpayer maintained the home for a qualifying dependent.

Answer C. A married taxpayer can claim head of household only if 'treated as unmarried.' One requirement is that the spouse not be a member of the taxpayer's household during the entire last six months of the year. Because the spouse was present in July (moved out July 10) and July is within the July-December period, Casey cannot be treated as unmarried. Casey remained married on December 31 and did not file a joint return, so the correct filing status is married filing separately.

Why not A: This is tempting because Casey meets the household-cost and qualifying-child parts of head-of-household qualification. It fails because a married taxpayer must also be treated as unmarried, which requires the spouse not be a household member during the entire last six months; the spouse's presence in July prevents that.

Why not B: This distractor appeals to the common mistake of equating physical separation with single status. Filing status depends on marital status on the last day of the year; without a divorce or separate maintenance decree Casey was still married on December 31 and cannot file as single.

Why not D: This misapplies the last-six-months rule. Although the spouse did not return after July 10, presence at any time in July counts as being a household member for that month, and July is part of the July-December six-month period, so Casey cannot be treated as unmarried.
