There may be some tax preparation software that allows you to bypass the "dependent" interview/filter for claiming head of household, but you will still have to exceed the "dependent" qualifications AND report the qualifying person's SSN on your tax return.
If that person's SSN has already been used on another return (claiming themselves or claimed by another), your e-filed HOH return will get rejected.
You can mail your HOH return, but should expect to hear from the IRS later in the year, asking for an explanation.
