Taxpayer Assistance and Service Act: Senate-Passed TAS Reforms, PTIN Oversight After Loving and How a Tax Bill Becomes Law for US CPA Firms

By Keshav Bansal, CA

The Taxpayer Assistance and Service Act (TAS Act) cleared the Senate unanimously on September 30, 2026—a Crapo-Wyden package of 65 bipartisan IRS reforms that still needs identical House passage and a presidential signature before it becomes law. For US CPA firms, the bill is both a service modernization bill (digitization, online accounts, refund tracking) and a preparer-oversight bill: Title V would give the IRS authority to deny, suspend or revoke Preparer Tax Identification Numbers (PTINs), closing a gap left after Loving v. IRS (D.C. Cir. 2014). It is also a clean lesson in how a tax bill becomes law under the Origination Clause.

What the Senate passed on September 30

Per the Senate Finance Committee release (September 30, 2026), Chairman Mike Crapo (R-Idaho) and Ranking Member Ron Wyden (D-Oregon) applauded the Senate’s unanimous approval of the Taxpayer Assistance and Service Act—65 bipartisan reforms to modernize the IRS, strengthen taxpayer rights and improve tax administration. The package had earlier advanced out of Finance by a 26–1 vote and carries endorsement from the National Taxpayer Advocate, among others.

As summarized by SW Accounting (week of October 11, 2026) and Thomson Reuters Tax News, the Senate text covers digitization of returns and correspondence, expanded online accounts, improved refund tracking, backlog and wait-time transparency, whistleblower-program strengthening and tighter paid-preparer oversight. Accounting Today and Ohio Society of CPAs coverage likewise frame the bill as a broad modernization package that now heads to the House.

Important timing: the Senate language is not yet law. SW Accounting states the bill returns to the House and is expected to be considered in the lame-duck session after the November midterm elections. Until the House passes identical text and the President signs, nothing in Title V or the service titles changes Circular 230, PTIN rules or firm workflows.

How a tax bill becomes law (and why H.R. 5349 was the vehicle)

Article I, Section 7—the Origination Clause—requires that bills for raising revenue originate in the House. In practice, the Senate often substitutes its preferred tax-administration text into a House-passed “shell” bill so the measure can move without violating that clause.

That is what happened here. Per the Congressional Record for September 30, 2026, the Senate discharged H.R. 5349 (originally the House-passed Tax Court Improvement Act) from Finance, agreed to the Crapo-Wyden substitute amendment, passed the amended bill and retitled it to improve IRS services for taxpayers. Congress.gov and Thomson Reuters confirm the Senate swapped TAS Act text into H.R. 5349. Because the chambers no longer have identical text, the measure returns to the House. Both chambers must then agree on the same language before presentment to the President.

For clients who ask whether Congress “passed” the TAS Act, the accurate answer for now is: the Senate passed it unanimously as a substitute to H.R. 5349; the House has not yet cleared that Senate version.

Why PTIN revocation matters after Loving

In Loving v. IRS, 742 F.3d 1013 (D.C. Cir. 2014), the D.C. Circuit held that 31 U.S.C. §330 does not authorize the IRS to regulate unenrolled tax-return preparers the way it regulates attorneys, CPAs and enrolled agents under Circular 230. Competency testing and continuing-education mandates for unenrolled preparers fell. PTIN use under IRC §6109 survived as a separate identification requirement, but demonstrated incompetence or disreputable conduct alone has not been a clear statutory basis to deny, suspend or revoke a PTIN.

Title V of the TAS Act—as described in the Senate Finance Committee section-by-section summary and secondary summaries from NAEA—would authorize the IRS to deny, suspend or revoke PTINs for suitability or education failures, incompetence or disreputable conduct, and would tighten penalties aimed at invalid or suspended PTINs, altered returns after taxpayer signature and refund misappropriation. Credentialed Circular 230 practitioners are generally treated differently from non-credentialed paid preparers under those proposals. Exact text and effective dates matter only if the House and President enact a final version—so treat Title V as pending legislation, not current Circular 230.

That oversight angle also matters lightly to UK readers who support US returns: ghost-preparer and refund-theft patterns are a client-protection issue. See our posts on ghost preparers and preparer responsibility and on the IRS whistleblower program and HMRC’s Strengthened Reward Scheme.

What US CPA firms should tell clients (and staff)

• Do not treat Senate passage as enactment. Service dashboards, PTIN revocation and new preparer penalties apply only after identical House passage and a presidential signature.
• Watch lame-duck calendars. Per SW Accounting, House consideration is expected after the midterms. Flag Ways and Means and floor notices so partners are not surprised by a sudden effective date.
• Separate Circular 230 firms from unenrolled shops. CPA firms already under Circular 230 should explain that Title V is aimed largely at non-credentialed paid preparers—while still tightening tools against ghost preparers and refund misuse that harm clients who used someone else.
• Keep PTIN hygiene tight now. Every signing preparer needs a valid PTIN on paid returns. Suspended or borrowed PTINs already create identity and due-diligence risk; Title V would raise the stakes further.
• Service modernization cuts both ways. Better online accounts and refund tracking help clients; backlog dashboards also raise response-time expectations. Update status-update habits if IRS portals improve.
• Whistleblower and §7216 remain live today. Strengthen intake when a client reports preparer misconduct, and keep §7216 consent and Circular 230 controls current for AI and offshore workflows.

A short firm checklist

• Assign one partner to track H.R. 5349 / TAS Act House action through lame duck; circulate a one-page “not yet law” note to tax staff.
• Inventory who in the firm (and any contractors) holds PTINs; confirm renewals and that no return uses another person’s number.
• Refresh client talking points on ghost preparers, refund routing and Form 14157 reporting—useful whether or not Title V becomes law.
• Map which clients rely on IRS online accounts or refund status tools so you can brief them if digitization provisions take effect.
• If a client already faces collection after a bad preparer experience, plan early; see our guide to IRS collection alternatives.
• Do not rewrite engagement letters for Title V until enacted text and effective dates are final.

Where this fits for Tax Brew readers

Legislative tracking and preparer-quality controls sit with your signing professionals; digitization and refund-status work still needs clean books and return prep capacity.
