The U.S. Supreme Court this morning rejected the Texas lawsuit to overturn the Affordable Care Act. Texas had argued that the imposition of a zero penalty rate for the individual mandate under the act undermined its constitutionality.

The court ruled that Texas, and the states joining it in the suit, lacked standing for their constitutional claims.

Some taxpayers have filed protective refund claims for Net Investment Income Tax and additional Medicare taxes imposed by the ACA, in hopes that the Court would retroactively invalidate the taxes via the Texas case. Those hopes are now dashed.
