My wife have been separated for 6 months not legally,she hasn't worked for 2 years can I claim the family for tax purposes? Can anyone else claim my family?

If you are not legally separated, you can sill file as married filing jointly if your wife agrees.

You need your wife's cooperation to make this happen, because SHE must also sign the return.

Approach your wife with a WIN-WIN attitude, offering her a portion of the refund in exchange for her help and cooperation.
