If I made 19,000 and claiming head of household with 2 dependents how much will I get

Assuming you are a full-year resident you should have $0 federal tax bill, so whatever has been withheld from your pay should be returned in your refund. However, there are often misconceptions about qualifications for filing as HoH and claiming dependents - if you can describe your relationship to the two dependents, their income levels, and whether they lived with you for the entire year we can check whether you can file as HoH.

Also, MOST of the time, if you are legally married, you CANNOT file as Head of Household.
