IRS Cancels Chemical Tax Hearing After Zero RSVPs

## Summary

The IRS planned a hearing about adding a special chemical mix to the Superfund tax list but canceled it because no one signed up to speak. Companies dealing with this chemical won’t see changes right now, but the petition to tax it is still in play. Keep an eye out for updates if you work with these substances, as tax rules could change later.
