01 · The brief
Plain-English summaryWhat this bill actually does

The bill (Tax Administration Simplification Act) amends the Internal Revenue Code to: (1) allow S corporation elections to be made as late as the tax return due date (including extensions) and permit the Secretary to issue implementing rules and treat some late revocations as timely for reasonable cause; (2) shift two estimated individual tax installment due dates (June 15→July 15 and September 15→October 15); and (3) extend the mailbox rule to permitted electronic filings and payments, treating transmission date as the filing/payment date if transmitted on time but received late. Effective dates vary by provision.
