I can answer the IRS portion. The IRS will not turn over your ex's tax information to you. The state court will have to compel your ex to produce them. The IRS cannot share your tax information with others by law. When the state compels it, they are making the person get their own information from the IRS and produce it for the court.
I agree with my colleague.

I agree with these attorneys, and want to add that your viable alternative is to register the foreign decree in the Texas court, and file a Motion to Enforce here, which would give you authority to subpoena the records, and askf or contempt if he does not comply.
