How Status Affects Credits
Child Tax Credit
All Statuses (if have qualifying child):
- $2,000 per child
- Same for all statuses
- Why: Not dependent on filing status
Earned Income Tax Credit (EITC)

- Why: Different thresholds
Example (1 child):
- Single: Phases out at ~$50,000
- Married: Phases out at ~$60,000
- Head of Household: Phases out at ~$55,000
Other Credits
Most Credits:
- Same for all statuses (if eligible)
- But income limits may vary
- Why: Some credits phase out at different levels
Marriage Bonus vs. Penalty
Marriage Bonus
When Married Pays Less:
- One spouse earns most income
- Combined tax < sum of individual taxes
- Why: Progressive brackets favor income disparity
Example:
- Spouse 1: $100,000 (single tax: $17,000)
- Spouse 2: $20,000 (single tax: $1,000)
- Combined single: $18,000
- Married: $17,000
- Bonus: $1,000
Marriage Penalty
When Married Pays More:
- Both spouses earn similar amounts
- Combined tax > sum of individual taxes
- Why: Brackets not exactly 2×, can create penalty
Example:
- Spouse 1: $60,000 (single tax: $8,253)
- Spouse 2: $60,000 (single tax: $8,253)
- Combined single: $16,506
- Married: $17,000
- Penalty: $494
Most Couples
Small Difference:
- Most couples: Small bonus or penalty
- Usually $0-$1,000 difference
- Why: Brackets designed to minimize penalty
