No. People who are not blood-related to you cannot qualify you to file as Head of Household. So even IF you can claim any of them as dependents, they do not qualify you to file HOH. You *might* be able to claim them as "qualified relative" dependents (even though they are not related to you) and get the $500 credit for other dependents. You cannot get any child-related credits for the 4 year old like earned income credit, child tax credit, or childcare credit.
As for your GF, her son and the grandchild--Did your GF have over $4200 of income in 2019? Did her son have over $4200 of income in 2019? If the answer is yes to either one, you cannot claim them as dependents. Is the son going to file a tax return and claim his child? If so you cannot claim the child.
WHO CAN I CLAIM AS A DEPENDENT?
You can claim a child, relative, friend, fiance (etc.) as a dependent on your 2018 taxes as long as they meet the following requirements:
Qualifying child
• They are related to you.
• They cannot be claimed as a dependent by someone else.
• They are a U.S. citizen, resident alien, national, or a Canadian or Mexican resident.
• They are not filing a joint return with their spouse.
• They are under the age of 19 (or 24 for full-time students).
- No age limit for permanently and totally disabled children
• They live with you for more than half the year (exceptions apply).
Qualifying relative
• They don't have to be related to you (despite the name).
• They cannot be claimed as a dependent by someone else.
• They are a U.S. citizen, resident alien, national, or a Canadian or Mexican resident.
• They are not filing a joint return with their spouse.
• They lived with you the entire year.
• They made less than $4,150 in 2018
• You provided more than half of their financial support. More info
When you add someone as a dependent, we'll ask a series of questions to make sure you can claim them.
