日本人の世帯主を英訳する場合"Head of the household(family)"が一番妥当ではないでしょうか。
釈迦に説法ですが他にも
Family head
Household master
Householder
などの言葉がありますが､ Family head 意外はあまり聞かないですね｡

Ref.　Fujitsu TranTestの辞書｡

This is a standard economic term and refers to the chief bread winner in a residence. Others in the household may or may not share the same family name. Also, the individual could be a man or a woman. He/she could also be living by himself.

I would not use the expression "head of a household", unless it was preceded by an article and contained within a sentence. For example, "The head of a household is the person responsible for filling out the families tax returns."

In a more general context the expressions "family head" or "the head of a family" are also correct. These expressions are more typically used by sociologists, however.

Grammatical correction: \"the families tax returns\" should have read \"the family\'s income tax form\".

That is the correct answer. Just the kanjis tell you that, and many forms you fill out in Japan have this item... I lived in all 12 years in Japan, and have been there many times.

in japan this term is not usually used for the head of the family.
