You have a few issues going on here:
- One, is understanding whether you have a partnership tax return filing requirement. You don't indicate whether you reside in a community property state. As stated by @Mike9241 this impacts the decision.
- Two, is understanding the filing of your personal tax return(s).
- Three, are you both active in the business?
- When did the business actually start?
- What expenses were incurred?
- Until we understand all of the above, it is not possible to provide good guidance.
- You need to address this quickly, as if you do have a partnership tax return filing requirement, this return is late and penalties have accrued.
