Should I include the amount in box 10 for dependent care benefits on my W-2 when calculating my taxable income?

No, you generally do not include the amount in Box 10 of your W-2 in your taxable income, unless you received more than the allowed exclusion or are not eligible for the exclusion.

What Box 10 represents

Box 10 of Form W-2 reports Dependent Care Benefits (DCB) provided by your employer, usually through:

• A Dependent Care Flexible Spending Account (DCFSA), or
• Employer-paid dependent care assistance

These amounts are reported for information purposes, not automatically taxable.

When Box 10 is NOT taxable

You do not include Box 10 in taxable income if all of the following are true:

• The benefits were used for qualified dependent care expenses
• The care allowed you (and your spouse, if married) to work or look for work
• The care was for:
  
  • A qualifying child under age 13, or
  • A qualifying dependent who is physically or mentally incapable of self-care
• The total benefits do not exceed the annual exclusion limit

Annual exclusion limits (unchanged for 2025):

• $5,000 for Married Filing Jointly or Single
• $2,500 for Married Filing Separately

If these conditions are met, the Box 10 amount:

• Is excluded from Box 1 wages
• Is not added back when calculating taxable income

When Box 10 IS taxable

Some or all of the Box 10 amount must be included in taxable income if:

1. You exceed the exclusion limit
   
   • Excess amounts are added back to Box 1 wages
2. You are Married Filing Separately and exceed $2,500
3. The care was not for a qualifying person
4. You did not have earned income (or your spouse did not, unless an exception applies)

In these cases:

• The taxable portion is included in Box 1
• You do not manually add Box 10 again (it’s already included)

Interaction with the Child and Dependent Care Credit

You cannot double-dip:

• Any expenses paid with Box 10 benefits:
  
  • Cannot be used again for the Child and Dependent Care Credit
• You must file Form 2441 to:
  
  • Reconcile Box 10 benefits
  • Determine any taxable excess
  • Calculate any remaining credit

Summary

• Do not include Box 10 in taxable income by default
• Only amounts over the allowed exclusion or not eligible become taxable
• Form 2441 determines the final tax treatment
