When Tie-Breaker Rules Apply

Tie-breaker rules apply when:

  • Both parents meet dependency requirements
  • Both parents claim the same child
  • No court order specifies who can claim
  • No Form 8332 has been signed

IRS Publication 501 (2024), "Tie-Breaker Rules": "If more than one person can claim the same child as a qualifying child, the tie-breaker rules determine who can actually claim the child. These rules apply only if all persons meet the requirements to claim the child."

Tie-Breaker Rule Order

The IRS applies tie-breaker rules in this order:

Rule 1: Parent vs Non-Parent

If one person is the parent and another is not, the parent wins.

Example: Father and grandmother both claim child. Father wins because he's the parent.

Rule 2: Parent with Longer Residency

If both are parents, the parent the child lived with longer wins.

Example: Child lived with father 8 months, mother 4 months. Father wins.

Rule 3: Parent with Higher AGI

If both parents have equal residency, the parent with higher adjusted gross income (AGI) wins.

Example: Child lived with both parents equally (6 months each). Father's AGI: $50,000. Mother's AGI: $40,000. Father wins.

IRS Publication 501 (2024): "If the child lived with each parent for the same amount of time, the parent with the higher adjusted gross income (AGI) can claim the child."

📋 Case Details

Citation: Johnson v. Commissioner, T.C. Memo. 2020-78, 2020 Tax Ct. Memo LEXIS 78 (Tax Ct. May 15, 2020)

Facts: Divorced parents both claimed same child. Child lived with father 7 months, mother 5 months. Both parents met dependency requirements. No court order or Form 8332.

Court Finding: Under tie-breaker rules, father had longer residency (7 months vs 5 months). Father had right to claim child. Father's claim allowed, mother's disallowed.

Key Takeaway: Parent with longer residency wins under tie-breaker rules.

50/50 Custody Situations

In 50/50 custody situations (child lives with each parent exactly 6 months), tie-breaker rules use AGI:

Example: 50/50 Custody

  • Child lives with father 6 months
  • Child lives with mother 6 months
  • Father's AGI: $60,000
  • Mother's AGI: $45,000
  • Result: Father can claim (higher AGI)

⚠️ Important: Document Residency

If you're relying on tie-breaker rules, document exactly how long child lived with you. School records, medical records, and lease agreements can prove residency.

How to Use Tie-Breaker Rules

Step 1: Determine If Both Parents Qualify

Both parents must meet all dependency requirements.

Step 2: Calculate Residency

Determine exactly how long child lived with each parent.

Step 3: Apply Tie-Breaker Rules

Apply rules in order: parent vs non-parent, then longer residency, then higher AGI.

Step 4: File Your Return

If you win under tie-breaker rules, file your return claiming the child.

Step 5: Respond to IRS Notices

If IRS questions your claim, provide documentation proving you win under tie-breaker rules.

Court Finding: Under tie-breaker rules, since residency was equal, parent with higher AGI (father) had right to claim. Father's claim allowed, mother's disallowed.

Anyone may arrange his affairs so that his taxes shall be as low as possible; he is not bound to choose that pattern which best pays the treasury. There is not even a patriotic duty to increase one's taxes. Over and over again the Courts have said that there is nothing sinister in so arranging affairs as to keep taxes as low as possible. Everyone does it, rich and poor alike and all do right, for nobody owes any public duty to pay more than the law demands.
