I didn’t get tax credit for my baby I had in 2017

[ChristyW]

Assuming your baby meet all the other dependent qualifications. A child born anytime in 2017 can be claimed on your 2017 taxes. A common reason for not getting credit is due to the time you selected the child lived with you.

When we ask how many months your newborn lived with you, always answer The whole year, even if your baby was born on the last day of 2017. The same holds true for any health care coverage questions if your newborn was insured from the date of birth. See: https://ttlc.intuit.com/replies/5820669
