A qualifying child dependent is normally worth a $2000 tax credit. A qualifying child dependent is someone who is your own biological or adopted child and who lives with you more than half the year and is under age 17. Any other dependent is worth a $500 credit.
if your qualifying child dependent is also a qualifying person for head of household status, and you remove that dependent and don’t have any other qualifying person for head of household status, then you would need to file as single or as married filing separately, both of which have higher tax rates than head of household and would cause additional tax to be owed.
