My fiance and I are still together and live together and had a kid but I want to claim him on my tax return on turbo tax how do I do it properly?

If you are a non-married couple who live together with your child, then only one of you can claim the child(ren) and the one not claiming the child does not enter anything at all on their tax return about the child.   The “sharing” of child-related credits you may have heard about is only possible between divorced or never married parents who live apart and share custody and who have a written agreement to share the credits.    The child’s SSN can only be entered on one tax return.   Any other return with the child’s SSN on it will be rejected.   If you are a family, then work out how to share the refund between yourselves.

[Opus 17]

The parent who wants to claim the children should list the child, say the child lives with them all year, there is NO custody agreement.  (The custody agreement question only applies to parents who live apart and share custody and have a court order, and does not apply to parents who live together and have an informal agreement how to file.)

The other parent does not list the child at all.  Just leave them off.

Who is "him" that you want to claim as a dependent on your tax return - your fiancé or the child? The previous replies assume you mean the child.

@Riven4 If by "claim him" you mean you want to claim your BF as a dependent, you could claim BF only if he lived with you all year, had less than $5200 of income not counting Social Security, and you provided over half his support.

IRS interview to help determine who can be claimed:
