How to Read an IRS Notice in Under Five Minutes
IRS Notices communicate new rules, transition relief, and compliance deadlines through the Internal Revenue Bulletin. Most Notices follow a predictable structure: a Purpose section that tells you what the Notice does, a Background section with legislative context, a Guidance section containing the actual rules, and (in many cases) sections on Effective Date and Reliance. If you read those sections in order, you can extract what you need from any Notice in under five minutes, spending your time on the substance rather than hunting for it.
The Structure of an IRS Notice
Notices are not all formatted identically, but the majority follow a common pattern. Using Notice 2020-75 as a concrete example (the Notice announcing forthcoming regulations on entity-level state and local income tax deductions for partnerships and S corporations), the structure breaks down into distinct sections.
Section 1: Purpose. This is the single most important paragraph. It tells you in plain language what the Notice does. In Notice 2020-75, the Purpose section announces that the Treasury Department and the IRS intend to issue proposed regulations clarifying that state and local income taxes imposed on and paid by a partnership or S corporation are deductible. One paragraph. One main point. Read this first and you immediately know whether the Notice is relevant to your client.
Section 2: Background. The Background section cites the statutory framework. Notice 2020-75's Background opens with IRC 164(a) and walks through the statutory provisions governing deductions for state and local taxes. This section exists for context, not for action. Skim it unless you need to understand the legislative history behind the guidance.
Section 3: Guidance (or Forthcoming Proposed Regulations). This is where the substance lives. Notice 2020-75 labels this section "Forthcoming Proposed Regulations." Other Notices use "Guidance," "Rules," or simply section numbers. Whatever the label, this section contains the actual rules, safe harbors, deadlines, or transition relief that the Notice provides. Read it carefully. Take notes on anything that affects current clients.
Effective Date and Reliance. Some Notices include these as explicit, numbered sections. Others embed them within the Guidance section. The Effective Date tells you when the rules apply: retroactively, prospectively, or for taxable years beginning after a specific date. The Reliance language tells you whether practitioners and taxpayers can rely on the Notice pending final regulations. Not every Notice includes explicit reliance language. When it does, it typically says something like "taxpayers may rely on the rules described in this notice until proposed regulations are published."
A Five-Minute Workflow
Once you recognize the structure, parsing a Notice becomes mechanical:
| Step | Action | Time |
|---|---|---|
| 1 | Read the Purpose section | 30 seconds |
| 2 | Check the Effective Date (scan for "effective for taxable years beginning after..." or similar language) | 15 seconds |
| 3 | Look for Reliance language (can you rely on this Notice before final regs?) | 15 seconds |
| 4 | Read the Guidance section for client-affecting rules | 3 minutes |
| 5 | Note the IRB citation for your research file | 15 seconds |
Step 1 tells you whether to keep reading. If the Purpose describes a provision irrelevant to your practice, you're done. If it's relevant, Steps 2 and 3 immediately answer the two questions every practitioner asks: when does this apply, and can I rely on it now?
Step 4 is where you spend most of your time. The Guidance section is where safe harbors, thresholds, calculation methods, and compliance requirements live. For Notice 2020-75, this is where the IRS specified that entity-level state tax payments are deductible by the entity, not subject to the $10,000 SALT cap that applies to individual taxpayers.
Step 5 is bookkeeping. Every Notice is published in a specific IRB issue (for example, Notice 2020-75 appeared in IRB 2020-49). Recording the IRB citation means you can find it again and cite it properly in a research memo.
Where Notices Sit in the Authority Hierarchy
Notices are not precedential. They do not carry the force of law. They represent the IRS's current position and often serve as a bridge between legislation and final regulations. In the tax authority hierarchy, Notices sit below Revenue Rulings and Revenue Procedures.
That said, practitioners rely on Notices extensively. When the IRS publishes a Notice announcing that it intends to issue regulations and that taxpayers may rely on the Notice in the interim, the practical weight is significant. Notice 2020-75's announcement about PTET deductibility gave practitioners enough confidence to recommend entity-level tax elections in dozens of states, years before final regulations were published.
The key question with any Notice is whether it includes explicit reliance language. If it does, you can advise clients based on the Notice's rules with reasonable confidence that the IRS will not penalize positions consistent with the published guidance. If it doesn't, the Notice is informational only, and you should treat the guidance as the IRS's stated intent rather than a binding commitment.
Common Types of Notices
Inflation adjustments. The IRS publishes annual inflation adjustments through Revenue Procedures (like Rev. Proc. 2024-40 for 2025 amounts), but occasionally uses Notices for specific provisions. These are straightforward: updated dollar amounts, effective for a specific tax year.
Transition relief. When Congress passes legislation late in the year or midyear, the IRS often issues Notices providing transition relief. Penalties may be waived for the first year a new provision applies. Filing deadlines may be extended. After OBBBA restored 100% bonus depreciation in July 2025, the IRS published several Notices and Fact Sheets providing guidance on how to apply the changes to returns already filed or in progress.
Guidance projects. Notices sometimes announce that the Treasury Department plans to issue regulations on a specific topic and request public comments. These Notices signal what the IRS is thinking and often include preliminary rules that taxpayers can rely on in the interim. Notice 2020-75 is a textbook example: it announced regulations, stated the expected rules, and granted reliance. When a Notice leads to final regulations, the result is a Treasury Decision. For a breakdown of how to read that document, see the Treasury Decision field guide.
Penalty relief and disaster relief. Natural disasters, public health emergencies, and systemic processing delays regularly trigger Notices providing penalty relief, extended filing deadlines, or postponed payment dates. These Notices tend to be short and specific: they list the affected areas, the relief period, and the deadlines that are extended.
Cross-Referencing: From Notice to Final Guidance
A Notice is often the first step in a longer guidance process. After the IRS publishes a Notice, the typical sequence is:
- Notice published in IRB (announces intent, may include interim rules)
- Notice of Proposed Rulemaking published in Federal Register (proposed Treasury Regulations)
- Public comments received
- Treasury Decision published (final Treasury Regulations)
To trace a Notice forward, search for Treasury Decisions that cite the original Notice number. To trace a Notice backward, check the Background section for the legislation or Code provision that prompted it.
The IRB is the publication vehicle for all of this guidance. Each weekly IRB issue contains Revenue Rulings, Revenue Procedures, Notices, Announcements, and other items. When you cite a Notice, include the IRB issue number (e.g., "Notice 2020-75, 2020-49 I.R.B.") so the reader can locate the original text.
For practitioners who handle questions involving the QBI deduction under IRC 199A, tracing the Notice-to-regulation path is particularly useful. The 199A regulations went through multiple rounds of proposed and final rules, each accompanied by Notices and preambles that explain the Treasury Department's reasoning. Understanding that reasoning can help you anticipate how the IRS will interpret edge cases.
The Bottom Line
IRS Notices are predictable once you learn the structure. Purpose tells you what. Effective Date tells you when. Reliance tells you whether you can act on it. Guidance tells you how.
Most practitioners spend too long reading Notices because they start at the beginning and read linearly. Start with Purpose. If it's relevant, jump to Effective Date and Reliance. Then read Guidance with your client's specific facts in mind.
For solo practitioners staying current on IRS guidance, building a Notice-reading habit takes less time than most people expect. The IRS publishes a new IRB issue every week, but only a fraction of the items in each issue will affect your practice. The five-minute workflow filters out the noise and gets you to the substance.
