Frequently Asked Questions
When should I update my W-4 after having a child?
Update your W-4 as soon as possible after your child is born. You can update it anytime during the year, but doing it soon after birth helps ensure proper withholding for the full year.
Do I need a Social Security Number to claim the Child Tax Credit?
Yes. Your child must have a valid Social Security Number to qualify for the Child Tax Credit. Apply for the SSN immediately after birth.
Can I claim the Child Tax Credit for a child born during the year?
Yes. A child born during the year counts as living with you for the full year and qualifies for the Child Tax Credit if they're under 17 at the end of the year (which they will be if born during the year).
What if my child is born in December?
A child born in December still qualifies for the Child Tax Credit for that entire year. They count as living with you for the full year, and if they're born in December, they're definitely under 17 at the end of the year.
Should I update my withholding before or after the child is born?
You can do either, but updating after birth is more accurate since you know the child exists and has an SSN. However, you can update before birth if you want to start getting the benefit earlier.
Can I claim medical expenses from pregnancy and birth?
Yes, if you itemize and medical expenses exceed 7.5% of your AGI. Pregnancy and birth-related medical expenses can be deductible medical expenses.
