@linespecialest34 why would your ex authorize their signature without seeing the entire return?
if you two are consenting to file Married- Filing Joint since you were not divorced as of 12/31/21, then consent is consent.
alternatively, you both can file Married - Filing Separate. It's not a problem. Then the ex doesn't have any right to review your return. More likely the tax each of you pay by going this route will be higher, but if there is something you don't want to ex to see, that is the cost of the ex not having full access. Each of you has the right to file in this manner. (but if you go this route note that you two must both either take the standard deduciton or both itemize - you can't mix and match).
Also, you may want to discuss filing joint with your divorce attorney. Even if both parties agree to sign, who is paying the tax that is due? who is getting the refund? how is that going to get agreed to? what happens later if something was missing or the IRS audits.
You have both gone your separate ways, why the would you want to file Joint?????? Talk to your attorney!!!
