IRS Notice 2026-58: 71 Obsolete IRB Guidance Documents—What the Third Cleanup Means for Form 1099-K, Capitalization and Your Tax Checklists | YCL | YCL CPA

By YCL CPA | YCL Tax, Accounting & Advisory

Bottom line in one breath

On Tuesday, September 29, 2026, the IRS released Notice 2026-58, which is published in Internal Revenue Bulletin 2026-42 dated Tuesday, October 13, 2026 (page 503). The notice obsoletes 71 revenue rulings, revenue procedures, notices and announcements that the IRS says "no longer provide useful information." It is the third cleanup of its kind, after Notice 2025-22 (9 documents) and Notice 2025-36 (83 documents), and the IRS expects more to follow. For small businesses, the most practical items are the Form 1099-K transition notices (Notices 2024-85, 2023-74 and 2023-10)—obsolete because the American Rescue Plan Act change they implemented was repealed by section 70432 of the One Big Beautiful Bill Act (OBBBA)—and a group of older capitalization and repair rulings whose subject matter is now covered by the final tangible- and intangible-property regulations. For most taxpayers, Notice 2026-58 does not by itself create a new filing obligation. The real risk is quieter: engagement letters, client memos, bookkeeping policies and tax-prep checklists that still cite guidance the IRS now treats as obsolete. This article is compliance planning to help you clean those up.

Background

On January 31, 2025, the President issued Executive Order 14192 (Unleashing Prosperity Through Deregulation), and on February 19, 2025, Executive Order 14219 (Ensuring Lawful Governance and Implementing the President's "Department of Government Efficiency" Deregulatory Initiative). In response, Treasury and the IRS began an ongoing review of regulations and Internal Revenue Bulletin (I.R.B.) guidance. The first two results were Notice 2025-22 (2025-19 I.R.B. 1427, nine documents) and Notice 2025-36 (2025-30 I.R.B. 192, 83 documents). Notice 2026-58 adds 71 more, bringing the three-notice total to 163 obsoleted I.R.B. documents. The IRS groups its reasons: guidance tied to repealed or amended Code sections; guidance whose subject is now addressed by final regulations; guidance that applied only to past years; requests for comments that are no longer needed; guidance that expired by its own terms; and guidance superseded by later documents. The IRS distributed the notice through IRS GuideWire on September 29, 2026; secondary coverage includes CPA Practice Advisor (October 5, 2026).

Old rules vs. Notice 2026-58

1. Form 1099-K transition notices: Before—Notice 2023-10 (calendar year 2022), Notice 2023-74 (2023) and Notice 2024-85 (2024 and 2025) treated those years as transition periods for the lower "$600" threshold enacted by ARP §9674(a), and Notice 2024-85 announced phased thresholds. Now—ARP §9674(a) was repealed by OBBBA §70432, so those transition notices are obsolete. Third-party settlement organization reporting follows the statute as amended by OBBBA (generally more than $20,000 and more than 200 transactions in a calendar year). Payment-card reporting and some state 1099-K rules are separate.

2. Repairs and capitalization rulings: Before—firms often cited Rev. Rul. 94-12 (incidental repairs), Rev. Rul. 2000-4 (ISO 9000 costs), Rev. Rul. 98-25 (storage-tank replacement), Rev. Rul. 89-23 (package design), Rev. Rul. 88-57 (railcar rebuilds) and Rev. Rul. 69-330 (SEC stock-registration costs). Now—obsolete; cite the final regulations instead, such as Treas. Reg. §1.162-4 (repairs), §1.263(a)-3 (improvements), §1.263(a)-4 (intangibles) and §1.263(a)-5 (transaction costs).

3. Partnership liabilities: Before—Rev. Rul. 88-77 (accrued but unpaid expenses and payables are not §752 liabilities). Now—obsolete; the definition sits in Treas. Reg. §1.752-1(a).

4. Estate and gift items: Before—rulings such as Rev. Rul. 56-290 / 57-78 (deducting a decedent's share of joint income-tax liability) and Rev. Proc. 2014-18 (an expired simplified portability-election extension). Now—obsolete; cite Treas. Reg. §20.2053-6(f) and the IRS's current portability relief procedure.

5. Information-reporting relief from past years: Before—Notices 2011-89 and 2013-56 (early 1099-K penalty relief), Notices 2012-34, 2012-11 and 2011-18 (broker basis and §6045B issuer reporting), Notice 2001-7 (attorney gross proceeds). Now—obsolete; the final regulations and current instructions govern.

6. Repealed or expired provisions: Examples include bond-allocation notices under repealed §§54–54F, windfall-profit-tax rulings, D.C. Enterprise Zone census tracts, and Rev. Proc. 98-47 (the §198 environmental-remediation election, which does not apply to costs after December 31, 2011).

7. What did *not* change: Obsoleting a document generally means it no longer has current use—not that the IRS reversed the underlying answer. Many conclusions now live in the statute or regulations, which is exactly why citations should be updated rather than ignored.

Self-check: does this affect you?

1. Do your client checklists or onboarding emails still say "you'll get a 1099-K if you receive over $600 / $2,500 / $5,000"? Those figures came from the ARP rule and the transition notices that are now obsolete. Update to the current statutory rule and keep the core message: all income is reportable whether or not a 1099-K arrives.

2. Does your fixed-asset or repair policy cite Rev. Rul. 94-12, 2000-4 or 98-25? Re-anchor it to §1.162-4, §1.263(a)-3 and, if you use it, the de minimis safe harbor election under §1.263(a)-1(f).

3. Do partnership basis workpapers cite Rev. Rul. 88-77? Point to §1.752-1(a).

4. Do estate-administration templates cite Rev. Rul. 56-290, 57-78, 55-334 or Rev. Proc. 2014-18? Replace with the regulations or current procedure.

5. Do you rely on an old IRS notice in a tax-position memo or audit file? Check it against the three cleanup notices (2025-22, 2025-36, 2026-58) before you file or respond.

6. Are you a cross-border seller using U.S. marketplaces or payment apps? 1099-K changes affect what forms you receive—not whether income is taxable in the U.S. or China.

Simplified example

Illustration only—not a prediction or promised outcome. Assume "Maple Craft LLC," a single-member LLC selling handmade goods through an online marketplace and a payment app, receives about $14,000 across 150 transactions through a payment app in calendar year 2026. Its bookkeeper's 2026 year-end checklist, written in 2024, says: "Per Notice 2024-85, expect a Form 1099-K above $2,500 for 2025 and $600 for 2026; reconcile 1099-K to sales." The same file has a repair policy citing Rev. Rul. 94-12.

1. 1099-K expectation: Notice 2024-85 is now obsolete. Under the statute as amended by OBBBA, a third-party settlement organization generally reports only when payments exceed $20,000 and transactions exceed 200, so Maple Craft may not receive a federal 1099-K from that app for 2026 (state rules and payment-card reporting can differ).

2. Income reporting: Maple Craft still reports all gross receipts on Schedule C. The checklist should reconcile bank deposits and platform reports, not just 1099-Ks.

3. Repair policy: Replace the Rev. Rul. 94-12 citation with §1.162-4 / §1.263(a)-3, and decide whether to attach the de minimis safe harbor election statement to the 2026 return.

4. Result: No new tax is created by Notice 2026-58; the work is updating the paper trail so the file reflects current law.

This ignores state thresholds, sales tax and self-employment tax details; it only shows how an obsolete citation can mislead a checklist.

Action timeline

1. Now (Tuesday, October 13, 2026): Download Notice 2026-58 and run a keyword search of your templates, engagement letters, policies and memos for the 71 document numbers—start with 2024-85, 2023-74, 2023-10, 94-12, 2000-4, 98-25, 88-77 and 2014-18.

2. By Thursday, October 15, 2026 (extended-return deadline): For any 2025 return still being finalized, confirm the 1099-K reconciliation and repair positions are documented under current law, not obsolete notices.

3. By Thursday, December 31, 2026: Refresh year-end bookkeeping and fixed-asset policies; confirm whether you will make the de minimis safe harbor election for tax year 2026.

4. Before January 2027 information-return season: Update client 1099-K messaging. Recipient copies of Forms 1099-K are generally due by Monday, February 1, 2027 (January 31, 2027 falls on a Sunday).

5. Ongoing: The IRS says more cleanups are coming. Add a quarterly check of new "obsoleting" notices to your compliance calendar.

6. Book a review with Gloria (Chenchen) Liu, CPA, if your files rely on older IRS guidance.

FAQ

Q: Does Notice 2026-58 change my 2026 tax bill?

A: Not by itself for most taxpayers. It declares 71 older I.R.B. documents obsolete because they no longer provide useful information. Your tax result still depends on the Code, regulations and current guidance; the practical task is updating any templates or memos that cite the obsoleted documents.

Q: Why are the Form 1099-K transition notices obsolete?

A: Notices 2024-85, 2023-74 and 2023-10 delayed and phased in the lower 1099-K threshold enacted by ARP §9674(a). OBBBA §70432 repealed that ARP change, so the transition periods no longer serve a purpose. Third-party settlement organization reporting now follows the statute as amended (generally more than $20,000 and more than 200 transactions), and all income remains reportable either way.

Q: If a revenue ruling is "obsolete," was its answer wrong?

A: Not necessarily. Many obsoleted rulings—such as Rev. Rul. 94-12 on incidental repairs or Rev. Rul. 88-77 on partnership liabilities—are now covered by final regulations. "Obsolete" generally means the document no longer has current use; cite the current regulation or statute instead.

Q: Will the IRS obsolete more guidance?

A: Yes. Notice 2026-58 states that Treasury and the IRS anticipate revoking or obsoleting additional similar guidance documents in the near future, so it helps to check citations periodically.
