Territorial Tax Parity Act of 2025

Enumerated powers · passes

Congress has the explicit power to 'lay and collect Taxes, Duties, Imposts and Excises' under Article I, Section 8, Clause 1. This bill modifies federal income tax sourcing rules and IRS authority, which is squarely within that enumerated power. The bill does not exceed federal authority because it concerns federal taxation, not regulation of intrastate commerce or other areas outside Congress's purview.

Bill of Rights · passes

The bill does not implicate the First, Second, Third, Fourth, Fifth, Sixth, Seventh, Eighth, Ninth, or Tenth Amendments. It does not restrict speech, religion, assembly, press, petition, arms, quartering, search and seizure, self-incrimination, trial rights, jury rights, or cruel and unusual punishment. The Fifth Amendment's Due Process Clause is not directly violated because the bill provides a legislative change to tax rules, not a deprivation of life, liberty, or property without due process. The Takings Clause is not implicated because tax liability is not a taking of property for public use.

Individual liberty · passes · severity: minor

The bill does not restrict an individual's control over their person, property, speech, labor, or belief. It changes the tax treatment of income, which is a legitimate exercise of the taxing power. While it may increase tax liability for some individuals, the government has a compelling interest in collecting revenue and ensuring tax compliance. The burden is on the government to justify the restriction, and here the restriction is a tax law change that applies uniformly and is not arbitrary.

Decentralization · raises concerns · severity: minor

The bill fails the decentralization test because it consolidates decision-making at the federal level regarding tax treatment of income from U.S. territories. While federal tax policy is inherently national, the bill reduces the ability of territories to set their own tax rules and grants the IRS discretionary authority to limit tax payments, which could undermine territorial fiscal autonomy. The questions: (1) individuals cannot handle federal tax policy on their own, (2) local communities cannot handle federal tax policy, (3) states cannot handle federal tax policy, but (4) the bill consolidates upward by overriding territorial tax sourcing rules and giving the IRS more discretion. This fails one question, resulting in a 'B' for decentralization.

Due process and takings · passes · severity: minor

The bill does not bypass procedural due process because it is a legislative change that applies prospectively and does not target specific individuals. It does not violate substantive due process because it is rationally related to the legitimate government interest of ensuring consistent tax treatment. The Takings Clause is not implicated because tax liability is not a taking of property. However, the IRS's discretionary authority to limit tax payments could raise concerns about arbitrary application, but the bill does not specify the criteria for such limits, which is a minor due process concern.
