Why Head of Household Often Means Lower Tax

• HOH offers a larger standard deduction than Single or Married Filing Separately. For 2024, the standard deduction is $21,900 for HOH (versus $14,600 for Single/MFS) (you can confirm current-year amounts in the Instructions for Form 1040 and Publication 17). Larger deductions reduce taxable income immediately (2024 Instructions for Form 1040; Publication 17).

• HOH also benefits from more favorable tax brackets compared to Single, which can further reduce tax.

Core Eligibility: Who Can File as Head of Household?
To claim HOH, you generally must meet all three requirements:

• Unmarried or “considered unmarried” on the last day of the tax year

  • Unmarried includes those legally divorced or legally separated by decree on December 31 (Publication 501).

  • Considered unmarried: You may still be legally married but qualify as HOH if all of these are true:

    • Your spouse did not live in your home during the last 6 months of the year,

    • You paid over half the cost of keeping up your home for the year, and

    • Your home was the main home for more than half the year of your qualifying child (who meets dependency rules or special tests).
      The IRS outlines these “considered unmarried” tests in divorce/separation guidance and filing status resources (Filing taxes after divorce or separation; Filing Status FAQs).

• You paid more than half the cost of keeping up the home for the year
  You must provide more than half of total household costs. Eligible costs include rent or mortgage interest, real estate taxes, utilities, repairs, and food eaten in the home. Clothing, education, and medical expenses don’t count toward this test. IRS training materials and filing status guides explain how to evaluate and document household costs (Publication 4491). Maintain clear records (receipts, lease/mortgage statements, property taxes, utility bills) to substantiate you paid more than half.

  Citation: IRS VITA/TCE Training—Filing Status (costs of keeping up a home, HOH rules, examples) Publication 4491 (Filing Status lesson).

• A qualifying person lived with you for more than half the year (with special exceptions)
  A qualifying person is generally either:

  • Your qualifying child (e.g., son/daughter/stepchild/foster child, or descendant) who meets age, relationship, residency, and support tests; or

  • A qualifying relative you can claim as a dependent (certain relatives qualify, including a parent).
    For HOH, a dependent parent can be your qualifying person even if they didn’t live with you. You must pay more than half the cost of keeping up the parent’s main home (such as their residence or qualified care facility) (Publication 4491).

  Citation: IRS VITA/TCE Training—Head of Household qualifying person rules and examples Publication 4491 (Filing Status lesson).

Temporary Absences Don’t Automatically Break Residency
Temporary absences due to illness, education, business, vacation, military service, or similar special circumstances are treated as time the qualifying person lived with you, provided you continue to maintain the home and reasonably expect their return (IRS training materials on HOH residency and temporary absence) (Publication 4491).

Head of Household for Divorced or Separated Parents

• Custodial parent can be HOH even if dependency is released: The IRS confirms you may still qualify for HOH even if the noncustodial parent claims the child as a dependent under a release (for example, via Form 8332). The key is that the child lived with you for more than half the year, you paid over half the cost of keeping up your home, and you’re unmarried/considered unmarried (IRS Filing Status FAQ).

• Noncustodial parent generally cannot be HOH: A noncustodial parent who claims a child as a dependent does not qualify for HOH based on that child because the child didn’t live with them for more than half the year (IRS Filing Status FAQ).

Tie‑Breaker Rules When More Than One Taxpayer Could Claim the Same Child
When multiple taxpayers could claim the same child, the IRS tie‑breaker rules determine who may claim the child (for dependency, HOH, and related benefits):

• A parent beats a non-parent;

• If both are parents, the parent with whom the child lived longer wins;

• If time is equal, the parent with the higher AGI wins;

• If no parent claims the child, then the eligible non-parent with the highest AGI may claim (subject to meeting all tests).
  The IRS lays out these rules in Publication 501 (Dependents section).

Citation: Publication 501 (tie‑breaker framework and dependency rules) Publication 501.

Common Mistakes That Cause HOH Denials

• Confusing dependency with HOH eligibility: A noncustodial parent who claims a child as a dependent under a release typically cannot claim HOH based on that child (Filing Status FAQs).

• Missing the “last six months” rule for “considered unmarried”: If your spouse lived in your home at any time during the last half of the year, you generally cannot claim HOH unless legally divorced or legally separated by year-end (Filing taxes after divorce or separation).

• Failing the “more than half the cost” test: Not tracking total household costs and your share can sink an otherwise valid HOH claim. Keep thorough documentation (Publication 4491).

• Relying on multiple support agreements: A dependent obtained only through a multiple support agreement is generally not a qualifying person for HOH (Publication 4491).

Documentation: What to Keep for Head of Household

• Proof of marital status at year-end (e.g., divorce decree or separation agreement) (Filing taxes after divorce or separation).

• Evidence of the qualifying person’s residency: school records, medical records, or childcare statements showing the child’s address and time in your home; for temporary absences, show you maintained the home and the absence was temporary (Publication 4491).

• Support and cost records: lease/mortgage, property tax statements, utility bills, grocery receipts, repair invoices, and evidence showing you paid them; if a dependent parent is your qualifying person, records that you paid over half of your parent’s home costs (Publication 4491).

• If divorced/separated: custody schedules and, if applicable, Form 8332 to show who claimed dependency—remember HOH is tied to the child’s residence and your support (Filing Status FAQs).

How to Decide if You Should Use Head of Household
Consider HOH if you:

• Are unmarried or “considered unmarried” at year-end,

• Paid more than half of the total cost to keep up your home during the year, and

• Had a qualifying person living with you more than half the year (or a qualifying parent you support).
  If you meet these tests, HOH typically provides tax savings compared to Single or Married Filing Separately. For 2024, HOH’s standard deduction is $21,900 versus $14,600 for Single/MFS; compare your outcomes using the IRS instructions and tables (2024 Instructions for Form 1040; Publication 17).

Real-World Examples

• Single parent living with child: You’re unmarried, your child lives with you more than half the year, and you pay more than half the household costs. You qualify for HOH (Publication 4491).

• Married but separated: Your spouse didn’t live with you for the last 6 months of the year; your home was the main home for your child for more than half the year; and you paid more than half the cost of keeping up the home. You’re “considered unmarried” and can file HOH (Filing taxes after divorce or separation).

• Dependent parent living elsewhere: You pay more than half the cost of keeping up your parent’s main home (e.g., their residence or a care facility), and you can claim your parent as a dependent. You can be HOH even though your parent doesn’t live with you (Publication 4491).

• Noncustodial parent with a dependency release: You properly claim the child as a dependent via a release (e.g., Form 8332), but the child didn’t live with you for more than half the year. You cannot claim HOH based on that child (Filing Status FAQs).

FAQs

• Can I be HOH if my ex claims our child as a dependent this year?
  Yes—if you’re the custodial parent (the child lived with you for more than half the year), you paid more than half the cost of keeping up your home, and you’re unmarried/considered unmarried. The IRS explicitly notes the custodial parent may still qualify for HOH even when the noncustodial parent claims the child as a dependent (Filing Status FAQs).
  Citation: Filing status | Internal Revenue Service.

• Do temporary absences (like college) affect the residency test?
  No. Temporary absences for education, medical care, military service, or similar reasons generally count as time living with you if you maintained the home and it’s reasonable to assume your child will return (Publication 4491).
  Citation: Publication 4491 (Filing Status lesson).

• What expenses count toward “keeping up a home”?
  Generally: rent/mortgage interest, property taxes, utilities, repairs, and food eaten in the home; not clothing, education, or medical expenses. IRS training materials provide examples and guidance (Publication 4491).
  Citation: Publication 4491 (Filing Status lesson).

• If my spouse and I lived apart but not for the full last six months, can I be HOH?
  Usually no—unless you were legally divorced or legally separated by year-end. To be “considered unmarried,” your spouse must not have lived in your home at any time during the last 6 months of the year, among other requirements (Filing taxes after divorce or separation; Filing Status FAQs).

Action Checklist for Claiming HOH

• Confirm your marital status at year-end and whether you are “considered unmarried” if still married (Filing taxes after divorce or separation).

• Identify your qualifying person and verify residency tests (Publication 4491; Publication 501).

• Calculate total annual cost of keeping up the home and confirm you paid more than half (Publication 4491).

• If divorced/separated, determine which parent is custodial (nights test) and review any dependency release—remember, HOH stays with the custodial parent (Filing Status FAQs).

• Keep documentation (leases, bills, custody schedules, school/medical records, etc.).

• Compare the HOH standard deduction to Single/MFS—you’ll likely see the HOH advantage (Instructions for Form 1040; Publication 17).
