Interstate Commerce Simplification Act of 2025This bill expands the definition of solicitation of orders to include business activities that serve an independently valuable business function apart...

Republicans control both chambers and Senate floor rules still require 60 votes. S.3027 sits in Senate Finance, chaired by Mike Crapo. Because the bill preempts state tax authority without affecting federal outlays or revenues, it is not viable for reconciliation under the Byrd Rule and thus needs bipartisan support. Blue‑state delegations and state‑tax groups (MTC) are positioned to oppose; business/taxpayer groups are supportive. Expect strong House GOP backing (similar language appeared in H.R.1 earlier this year), but Senate cloture math is the obstacle; passage odds this session are low.

Breakdown: expected support by chamber/party

Bill: S.3027 (Interstate Commerce Simplification Act of 2025) — expands the P.L. 86‑272 “solicitation of orders” immunity to cover activities that facilitate solicitation even if they have independent business value. Committee of referral: Senate Finance. Context below reflects current control and rules. [3]Senate Finance Committee — Crapo Named Chairman of Senate Finance Committee (11…

  • Senate landscape: GOP majority; chamber rules (filibuster preserved) mean 60 votes are required for standalone passage. Republicans hold 53 seats; Democrats 45 plus 2 independents caucusing with Democrats. Majority Leader: John Thune. [1]U.S. Senate — U.S. Senate: Party Division[2]U.S. Senate — U.S. Senate: Complete List of Majority and Minority Leaders
  • Reconciliation is a non‑starter for this bill: provisions with no federal budget effect or merely incidental budget effects are struck under the Byrd Rule. S.3027 changes state taxing power, not federal outlays/revenues. It would need 60 on the floor. [4]Congressional Research Service — CRS: The Reconciliation Process — Frequently A…
  • Baseline party posture (Senate):
  • - Republicans: generally favorable to curbing state income‑tax reach into interstate e‑commerce; Finance Chair Crapo sets a receptive agenda. Expect most Republicans to be "yes" in committee and on the floor. [3]Senate Finance Committee — Crapo Named Chairman of Senate Finance Committee (11…
  • - Democrats: likely skeptical/opposed, especially from states that have adopted MTC’s 2021 internet‑activity guidance (e.g., NY, NJ) and are defending it in court. [6]Grant Thornton — Grant Thornton: New York court upholds internet-activities reg…[7]RSM US — RSM: New Jersey adopts revised guidance on P.L. 86-272 internet activi…
  • Swing space (Senate): bill would need at least seven Democratic/independent votes even if all 53 Republicans back it; any GOP defections increase that ask. [1]U.S. Senate — U.S. Senate: Party Division
  • House landscape: GOP majority; Speaker Mike Johnson. Ways & Means Chair Jason Smith has prioritized tax policy and earlier advanced a House package (H.R.1) that included similar PL 86‑272 expansion language. Expect near‑party‑line GOP support; Democratic opposition. [8]Associated Press — AP: Mike Johnson narrowly reelected House Speaker (119th Con…[9]House Committee on Ways and Means — House Ways & Means: Smith Announces 119th C…[5]Greenberg Traurig — Greenberg Traurig: Interstate Commerce Tax Protection — Pro…
  • Calendar friction: the House has been intermittently out of session around the shutdown fight this fall, constraining near‑term floor time for add‑ons or follow‑ons. [10]Associated Press — AP: House out of session as shutdown drags (October 2025)

Key legislators and likely swing votes

Focus on members with procedural leverage or demonstrated cross‑party flexibility.

  • Mike Crapo (R‑ID), Senate Finance Chair — controls hearings/markups; has publicly sketched a pro‑business tax agenda for the 119th, making committee movement plausible. [3]Senate Finance Committee — Crapo Named Chairman of Senate Finance Committee (11…
  • Ron Wyden (D‑OR), Finance Ranking Member — leads the Democratic counterweight on tax; has actively organized caucus positions in Finance this year. Expect him to marshal opposition tying the bill to state‑revenue preemption. [11]Senate Finance Committee — Senate Finance: Crapo, Wyden Announce Subcommittee A…[12]Web search · turn 13 #3
  • Potential GOP defections to watch: Susan Collins (ME) and Lisa Murkowski (AK) consistently rank among the Senate’s most bipartisan Republicans; either could condition support on state‑sovereignty concerns or prefer narrower drafting. [13]The Lugar Center — Lugar Center Bipartisan Index: 2023 Senate Scores (Collins,…
  • Potential Democratic gets: Mark Warner (VA) and Maggie Hassan (NH) occasionally cross lines on economic nominations; both supported advancing Treasury Sec. Bessent through Finance, indicating pragmatic deal space — but both represent states aligned with preserving state tax authority, limiting odds.

  • State‑aligned blocs: New York and New Jersey delegations (e.g., Schumer/Gillibrand; Booker/menendez successor) are incentivized to oppose after their states adopted MTC‑style rules and defended them in court.

Leadership positions and procedural dynamics

Where leadership stands, and what tools they control.

  • Senate leadership: Majority Leader John Thune has not signaled any rules change; the 60‑vote filibuster remains, making bipartisan buy‑in mandatory for S.3027. Floor time is at a premium amid broader fiscal fights. [2]U.S. Senate — U.S. Senate: Complete List of Majority and Minority Leaders
  • Senate Finance control: Chairman Crapo can notice hearings/markups swiftly; Ranking Member Wyden can rally unified Democratic opposition and drive messaging around state revenue and federalism. [3]Senate Finance Committee — Crapo Named Chairman of Senate Finance Committee (11…[11]Senate Finance Committee — Senate Finance: Crapo, Wyden Announce Subcommittee A…
  • Reconciliation constraint: Earlier in 2025, House Republicans tucked a similar PL 86‑272 expansion into H.R.1 (“One Big Beautiful Bill”), but Senate review subjected numerous non‑budgetary items to Byrd‑Rule strikes. A comparable PL 86‑272 rider would be at acute risk in any reconciliation vehicle. [5]Greenberg Traurig — Greenberg Traurig: Interstate Commerce Tax Protection — Pro…[15]Web search · turn 11 #6
  • House posture: Speaker Mike Johnson and Chairman Jason Smith have the agenda space to move companion language; the chamber has already demonstrated willingness to include PL 86‑272 clarification in its flagship package.

Substantive context shaping votes

Why stakeholders line up as they do.

  • MTC’s 2021 internet‑activity guidance narrowed P.L. 86‑272 protection for online sellers; several states followed (notably NY by regulation, NJ by rule/bulletin). Business/taxpayer groups have pushed for a federal fix. [16]Multistate Tax Commission — MTC: Statement of Information Concerning Practices…[6]Grant Thornton — Grant Thornton: New York court upholds internet-activities reg…[7]RSM US — RSM: New Jersey adopts revised guidance on P.L. 86-272 internet activi…
  • Courts split on state implementation: California’s guidance was voided on APA grounds; New York’s internet‑rule was upheld prospectively but retroactivity limited. These cases keep pressure on Congress but also embolden state defenders. [17]Grant Thornton — Grant Thornton: California court invalidates FTB’s P.L. 86-272…[6]Grant Thornton — Grant Thornton: New York court upholds internet-activities reg…
  • Background law: Wrigley (1992) defines “solicitation” scope; Wayfair (2018) ended physical‑presence for sales/use tax nexus. Members and staff will anchor arguments in these precedents. [18]Cornell LII — Wrigley (1992) — LII summary/opinion[19]Cornell LII — South Dakota v. Wayfair (2018) — LII summary/opinion
  • Advocacy signals: National Taxpayers Union has publicly urged congressional action to protect interstate commerce from state income‑tax expansion via the MTC framework — a message resonant with House/Senate tax writers on the right. States and MTC argue the opposite. [20]Web search · turn 3 #8[21]Web search · turn 3 #7

Assessment: likelihood of passage

Bottom‑line, power-and-procedure view.

  • Senate committee: Likely reports if scheduled (GOP majority on Finance), but minority will file strong views; expect party‑line or near‑party‑line vote. [3]Senate Finance Committee — Crapo Named Chairman of Senate Finance Committee (11…
  • Senate floor: Low likelihood this session. Absent reconciliation protection — unavailable here — bill needs 60 votes. With unified Democratic opposition from state‑aligned delegations (NY/NJ) and a handful of potential GOP skeptics, clearing cloture is improbable in 2025. Confidence: low. [4]Congressional Research Service — CRS: The Reconciliation Process — Frequently A…[6]Grant Thornton — Grant Thornton: New York court upholds internet-activities reg…[7]RSM US — RSM: New Jersey adopts revised guidance on P.L. 86-272 internet activi…
  • House: If a Senate vehicle arrived, House GOP leadership could pass it on a near‑party‑line vote, consistent with earlier inclusion in H.R.1. Calendar is the constraint, not votes. Confidence: moderate. [5]Greenberg Traurig — Greenberg Traurig: Interstate Commerce Tax Protection — Pro…[8]Associated Press — AP: Mike Johnson narrowly reelected House Speaker (119th Con…
  • Timing: With shutdown/CR fights consuming floor time in October and committee bandwidth focused on FY26 and TCJA‑expiring provisions, standalone passage before year‑end is unlikely. Next realistic window is hitching to an early‑2026 tax or business vehicle — but Byrd‑Rule limits still apply. Confidence: low.
