No, the employer's match to your spouse's 401-K does not need to be reported anywhere on the tax return.
Employer's match is part of the company's benefit package to entice people to want to work for the employer. Employers also receive a tax benefit for contributing to employee 401(k) accounts. A company match has the power to greatly increase the value of an employer-sponsored retirement savings account. It does not get reported on any tax documents except for informational purposes only.

The employer match is *not* reported on the employee's W-2 (except possibly for informational purposes only, not in in box 12). With regard to contributions to a 401(k), only the employee's elective deferrals (code D) and Roth contributions (code AA) are reported in box 12 of the W-2.
