<prompt> Human: My boyfriend and I moved into a 3bdrm apartment together about a month ago. We split the rent and utility costs 5050. We buy our own food, clothes, etc separately since we have such different tastes.I entered a 1 for myself since Im not claiming any dependents and I entered a 1 for being single and unmarried. But I dont know what to enter for the head of household box. Should I enter a 1? Should I leave it blank? I feel like I should leave it blank since Im not claiming any dependents.I assume both of us will continue to file taxes separately until we actually get married. Is this the best choice? I only have a single job and he only has a single job. The only costs we split are the rentutilities. Everything else is paid separately and not shared.  <response>: In this situation, you are both single individuals for tax filing purposes.
