EFIN Verification Act of 2026

Enumerated powers · passes

Article I, Section 8, Clause 1 grants Congress the power to 'lay and collect Taxes, Duties, Imposts and Excises.' Requiring validation of electronic filing identification numbers (EFINs) before a tax return may be filed is a reasonable procedural measure to ensure the integrity of federal tax collection. This is well within the necessary and proper authority under Article I, Section 8, Clause 18 to carry out the taxing power.

Bill of Rights · passes

The bill does not infringe any provision of the Bill of Rights. It does not restrict speech, religion, assembly, press, or petition (First Amendment). It does not regulate firearms (Second Amendment). It does not authorize any search or seizure (Fourth Amendment). It does not compel self-incrimination or deprive anyone of life, liberty, or property without due process (Fifth Amendment). It does not affect criminal trials or punishment (Sixth, Eighth Amendments). It does not violate the Ninth or Tenth Amendments, as it is a proper exercise of federal taxing power.

Individual liberty · passes

The bill imposes a minimal administrative requirement on tax preparers and filers — that an EFIN be validated as active before electronic filing. This does not restrict what a person may do with their own person, property, speech, labor, or belief. It is a routine procedural safeguard for federal tax administration, not a restriction on individual liberty. The government has a compelling interest in preventing fraudulent tax filings, and the burden on individuals is negligible.

Decentralization · passes

The bill passes all four questions of the decentralization test. (1) An individual or family cannot handle EFIN validation on their own because EFINs are issued by the IRS for the purpose of federal tax filing. (2) A local community or county cannot handle this because it involves a federal tax identification system. (3) A state cannot handle this because the IRS administers federal tax returns, not state returns. (4) The action does not consolidate decision-making upward beyond the minimum necessary — the federal government is the only entity that can validate its own tax filing credentials. The Tenth Amendment is not implicated because the bill regulates only the federal tax filing process, not any area reserved to the states.

Due process and takings · passes

The bill does not bypass due process or take property without just compensation. It requires the IRS to develop a program to validate EFIN status in real time, which provides fair notice and an opportunity to comply. There is no presumption of innocence issue, no deprivation of property, and no arbitrary government action. The requirement is procedural and non-punitive.
