The IRS Just Published 121 Guidance Projects for 2026-2027. Here's What That Means for Your Provision.
The IRS released its 2026-2027 Priority Guidance Plan on September 29. 121 projects. OBBBA implementation dominates. Here's what every tax director needs to adjust in their ASC 740 process now.

Findings in the original version: the September 29 plan identifies 121 projects; it is a work programme, not a promise to issue every item or a new tax law.
On September 29, 2026, the Treasury Department and IRS released the 2026-2027 Priority Guidance Plan — 121 guidance projects the government intends to work through before September 30, 2027. That document is not background reading. It is a map of every regulatory uncertainty currently sitting inside your ASC 740 provision.
Most tax departments read the Priority Guidance Plan the way they read a Federal Register notice: they note it, file it, and return to the work in front of them. That is the wrong approach. The PGP tells you exactly where the IRS knows the rules are unsettled. Every item on that list is a potential adjustment to your deferred tax assets, your effective tax rate estimate, or your uncertain tax positions. Your provision model needs to account for that uncertainty now — not when the guidance finalizes.
What the 2026-2027 PGP Actually Covers
The headline focus is OBBBA — the One Big Beautiful Bill Act signed July 4, 2025. The PGP lists continued OBBBA implementation as its first priority. That means regulations on the Section 250 deduction changes, the foreign tax credit revisions, and the deduction eligible income calculation are all still in draft form. Your current-year provision is running on statutory text and temporary guidance. That gap matters.
Beyond OBBBA, the 2026-2027 PGP covers six major clusters that corporate tax departments need to track:
- Digital asset taxation: Staking income, token classification, and basis tracking rules are explicitly on the list. If your company has any treasury or compensation exposure to digital assets, your provision model almost certainly needs an uncertain tax position reserve.
- Deregulation and burden reduction: The IRS is reviewing regulations it considers burdensome — including some that currently govern your deferred tax calculations. Changes here can move your DTAs and DTLs without any change to your business.
- Tax-exempt organizations: Relevant for corporate foundations, employee benefits trusts, and any captive structures with tax-exempt entities in the chain.
- Tribal tax issues: Narrow but high-impact for companies with operations on tribal lands.
- Section 174 capitalization: The OBBBA made permanent changes to R&D cost capitalization. Final regulations on what qualifies and what does not are still pending. Your R&D-related deferred tax asset is sitting on temporary rules.
- CAMT and book minimum tax interaction: The Corporate Alternative Minimum Tax interaction with ASC 740 is on the list. The KPMG guidance on CAMT deferred tax treatment remains advisory, not regulatory. That ambiguity belongs in your provision disclosure.
The ASC 740 Implications Are Not Academic
Here is what tax directors get wrong about the Priority Guidance Plan: they treat it as a future-event list rather than a current-period accounting input.
Under ASC 740-10-25, uncertain tax positions require a two-step analysis — recognition (more likely than not) and measurement (largest amount with greater than 50% cumulative probability). The PGP does not directly establish positions. But it tells you which statutory provisions have unsettled regulatory interpretation. An item on the PGP is a signal that the IRS sees enough ambiguity to warrant formal guidance. That ambiguity is exactly what drives UTB exposure.
Consider Section 174. The OBBBA made permanent the 5-year domestic capitalization requirement and the 15-year foreign capitalization requirement. But the regulations defining which costs qualify as "specified research or experimental expenditures" are still not final. Companies are making classification decisions today — in their provision models — on the basis of proposed regulations and temporary rules. That is a UTB risk. The PGP tells you the IRS agrees it is open.
The same logic applies to the OBBBA's changes to the Section 250 deduction for GILTI and FDII. Final OBBBA regulations on the foreign tax credit and Section 951A are explicitly on the PGP. Companies are computing their deferred tax assets on GILTI high-tax exclusion elections using temporary rules. When final regulations publish — the PGP signals that is a 2027 event — those DTAs will need to be remeasured.
How to Build the PGP Into Your Provision Process
Most provision models are built to handle enacted law, not regulatory uncertainty. That is a design limitation that creates surprises at year-end. Here is how to address it systematically.
Map Every Open PGP Item to a Provision Schedule
The 121 PGP items fall into roughly 15 categories that touch corporate income tax. For each one, identify the specific schedule or calculation in your provision model that the pending guidance affects. This is a one-time mapping exercise. Once you have it, every time a new PGP publishes you can run the map against the new items and identify what changed.
At Clarity Tax, this is exactly the kind of structured mapping our knowledge graph supports. Each regulatory item in the 2026-2027 PGP corresponds to one or more ASC 740 conceptual nodes in our taxonomy. When the graph is updated to reflect the PGP, every provision calculation connected to those nodes gets flagged automatically.
Build Explicit Sensitivity Tables for Open Items
For each PGP item that materially affects your provision, build a sensitivity table: what does the deferred tax asset or ETR look like under the most conservative regulatory interpretation versus the most favorable? The spread defines your regulatory uncertainty range. That range belongs in your Q4 provision memo and in your year-end disclosure.
Companies that do this work in Q4 are ready for the auditor conversation. Companies that skip it discover the sensitivity analysis requirement during fieldwork.
Revisit Your UTP Reserves for PGP-Adjacent Positions
The PGP is a reliable signal of what the IRS views as priority examination issues. A position you have taken that relies on regulatory interpretation in a pending-guidance area is a high-audit-probability position. Review your UTP reserves against the 2026-2027 PGP list. If you have recognized a benefit in an area the IRS explicitly flagged for guidance, your reserve is understated.
Update Your ETR Disclosure for Regulatory Uncertainty
ASU 2023-09 requires disaggregated rate reconciliation. The 2026-2027 PGP gives you the language to explain regulatory uncertainty items in your rate reconciliation without creating new technical exposure. "Pending regulatory guidance on \[Section 174 / GILTI / CAMT\]" is a disclosure category that belongs in the Q4 reconciliation for most large corporations.
The Digital Asset Question Your Provision Is Probably Avoiding
The 2026-2027 PGP makes digital asset taxation an explicit priority. Treasury has been issuing guidance in fragments — staking income rules, broker reporting requirements, wash sale extension proposals. Final, comprehensive digital asset tax regulations are on the PGP for a reason: the rules are still not settled.
Corporate treasury teams are now routinely holding bitcoin, ether, and tokenized treasury instruments. Compensation arrangements include RSUs settled in tokens. R&D programs use on-chain infrastructure that creates tax events. Every one of these creates ASC 740 exposure — mark-to-market questions, realization timing questions, character questions — that is sitting in an unsettled regulatory environment.
If your provision model has no digital asset schedule, and your company has any digital asset exposure, you have a gap. The PGP tells you the IRS plans to close the regulatory uncertainty. Your provision needs to reflect the current open question, not assume the favorable outcome.
What to Do Monday Morning
1. Download the 2026-2027 Priority Guidance Plan from IRS.gov and assign ownership of each relevant item to a provision team member. Treat it like an open items list, not a policy document. 2. Run a PGP-to-provision mapping exercise for the 15 corporate income tax categories. Every open item maps to at least one schedule in your model. Identify which DTAs, DTLs, and UTBs are affected by pending guidance. 3. Build Q4 sensitivity tables for your top five PGP exposure items. Quantify the range. Put the range in your Q4 provision memo before December 31. 4. Review your Section 174 and GILTI deferred tax positions against the actual language of the temporary regulations — not the memo you wrote when they were proposed. If final regulations diverge from your current model, you need an estimate of the impact before year-end close. 5. Add a PGP review to your annual provision calendar as a recurring September/October task. The PGP publishes every fall. Your provision should respond to it every fall.
The Priority Guidance Plan is a free, comprehensive disclosure by the IRS of where it thinks the tax law is uncertain. Tax departments that use it as a provision input are building more accurate models with fewer year-end surprises. Those that file it away are carrying undisclosed regulatory risk into their audits.
The knowledge graph infrastructure behind DisclosureIQ is designed specifically for this kind of regulatory-uncertainty tracking. When the IRS publishes a new PGP, the nodes that correspond to open guidance items are flagged, and every provision calculation connected to those nodes surfaces for review. That is what it means to treat tax law as an operating system rather than a lookup table. For more on how this infrastructure works, see our posts on ASC 740 provision accuracy and deterministic-first AI architecture for tax.
Your Q4 provision window is open. DisclosureIQ maps every open IRS guidance project to your specific deferred tax positions — so you know what's uncertain before your auditors ask.
