If I file single is that head of house hold?

[JulieCo]

No, single and head of household are two different filing statuses. 

To qualify for head of household, you must meet the following guidelines listed out below.

For tax year 2018, you can qualify for Head of Household if you:

1. Were unmarried as of December 31, 2018 and
2. Paid more than half the cost to run your (or a qualifying parent's) home in 2018 (rent, mortgage, utilities, etc.) and
3. Supported a qualifying person.
