In 2026, AI is transforming tax preparation and IRS communications. AleAIT Solutions' 2026 guide describes tax software that "reads a W-2 in seconds, flags a missing form before it turns into an audit risk, and answers a tax-code question the way a senior associate would — instantly, in plain English." TaxGPT lets users "ask questions in plain English and receive answers linked directly to the IRC, Treasury Regulations, IRS rulings, and case law." The IRS uses AI voicebots and chatbots to "answer common taxpayer questions more quickly," according to the GAO. HeyEduardo's 2026 guide notes that AI "excels at explaining complex language in plain terms."

But the Tax Adviser's 2026 coverage of the IRS advisory panel reveals the gap that AI has not closed: "Improved outreach and education — including plain-language resources — would help taxpayers comply correctly the first time and reduce downstream enforcement burdens."

The advisory panel is saying: taxpayers still cannot understand their tax communications, and the result is compliance failures, penalties, and enforcement costs. AI can translate tax jargon into plain English — but most tax AI tools and IRS communications still generate content at a reading level that most taxpayers cannot follow.

The tax communication readability problem

1. Tax code jargon

Tax communications use specialized terminology: "adjusted gross income," "itemized deductions," "earned income tax credit," "qualified business income deduction," "pass-through entity," "net investment income tax," "alternative minimum tax." These terms are precise for tax professionals and opaque to most taxpayers. When AI generates a tax explanation using this terminology, the taxpayer who needs to understand their filing obligation cannot follow it.

2. IRS notice complexity

HeyEduardo's 2026 guide specifically mentions "an ambiguous line on an IRS notice" as something AI can help with. IRS notices are notoriously complex — citing code sections, referencing forms by number, and using regulatory language that most taxpayers have never encountered. An AI that translates an IRS notice into plain English is valuable — but the translation needs to go far enough to reach the taxpayer's reading level.

3. Filing instructions that exclude

Tax software generates filing instructions, deduction explanations, and compliance guidance. When these are generated at a professional reading level, the taxpayer who is self-filing — without a tax professional — cannot understand what to do. WeAreMitu's 2026 guide notes that AI "can translate IRS jargon into plain English or Spanish, explain whether a home office deduction or mileage rule even sounds relevant to your situation." The translation is the value — but it needs to reach the taxpayer's reading level.

4. The compliance-stakes gap

Tax communications have direct financial consequences. A taxpayer who does not understand their filing instructions, deduction eligibility, or audit notice may file incorrectly, miss deadlines, or fail to respond to IRS correspondence. The result: penalties, interest, audit risk, and enforcement costs. The IRS advisory panel specifically identified plain-language resources as a way to "reduce downstream enforcement burdens."

Why AI-generated tax communications are hard to read

1. Tax code as training data

AI tax tools train on the Internal Revenue Code, Treasury Regulations, IRS publications, and tax professional documentation — all written at a college reading level or above with tax terminology, legal references, and regulatory language. The generated content reproduces this register.

2. Professional accuracy over taxpayer comprehension

Tax AI tools optimize for professional-grade accuracy: every code citation, every regulation reference, every form number. This produces content that satisfies tax professionals but not taxpayers. TaxGPT's "View Steps" feature "exposes the full reasoning path behind an answer" — valuable for a CPA, overwhelming for a self- filing taxpayer.

3. The "plain English" that is not plain enough

Multiple 2026 sources describe AI translating tax jargon into "plain English." HeyEduardo says AI "excels at explaining complex language in plain terms." AleAIT says the software answers questions "in plain English." WeAreMitu says AI "translates IRS jargon into plain English or Spanish." But "plain English" in the tax context often means "less jargon than the tax code" rather than "readable by the average taxpayer." A translation from grade 16 to grade 12 is an improvement — but the average taxpayer reads at grade 8.

4. IRS Circular 230 compliance

Thomson Reuters' 2026 guide reports that the IRS released OPR Alert 2026-19 aligning AI requirements with Circular 230 obligations. Tax professionals using AI must ensure the output meets professional standards. This compliance requirement is necessary, but it can bias the AI output toward professional register rather than taxpayer readability.

The fix: a readability layer for tax communications

The fix is to add a readability step to the tax AI pipeline — after the professional-grade explanation and before the taxpayer receives it:

1. AI generates the tax explanation — the code interpretation,

notice explanation, or filing instruction

1. Readability layer: the explanation is simplified to a 5th-

grade reading level with plain language

1. Tax professional reviews the simplified version for accuracy
2. Taxpayer receives the plain-language version alongside the

professional version

This ensures the taxpayer gets both accurate information and understandable communication.

How ELI5 AI helps tax teams

ELI5 AI is a free, no-login text simplifier that takes any tax communication and rewrites it at a 5th-grade reading level with four levels side-by-side: 5-year-old, 10-year-old, teenager, and adult.

For tax software and IRS teams, the workflow is:

1. AI generates the tax explanation (code interpretation, notice

explanation, filing instruction, deduction eligibility)

1. Paste it into ELI5 AI — get a plain-language version at four

reading levels

1. Use the appropriate level:

• Adult level for tax professionals (accurate but clear)
• Teenager level for taxpayer-facing explanations (plain English

that the average taxpayer can follow)

• 10-year-old level for filing instructions (step-by-step in plain

language)

• 5-year-old level for the key action the taxpayer must take

("File this form by April 15. You owe $2,400.")

1. Publish both versions — the professional version for the tax

preparer, the plain-language version for the taxpayer

What tax teams should do now

• Audit your AI-generated tax communications for readability.

Sample 10 tax explanations, notice interpretations, or filing instructions. If they score above grade 12, taxpayers are struggling to understand their own tax obligations

• Simplify IRS notice explanations. Use

ELI5 AI to produce a plain-language version of every IRS notice explanation. The taxpayer needs to understand: what the notice says, what it means, and what to do

• Simplify filing instructions. Step-by-step in plain language.

"Fill in line 7 of Form 1040 with the number from box 1 of your W-2" beats "Enter the amount from Form W-2, box 1, on line 7 of Form 1040, subject to the adjusted gross income limitations under IRC Section 62"

• Follow the IRS advisory panel recommendation. The panel

specifically called for "plain-language resources" to "help taxpayers comply correctly the first time." ELI5 AI provides the readability layer that delivers plain-language resources at scale

• Track compliance against readability. If simplified tax

communications reduce filing errors, missed deadlines, and penalty assessments, readability is a compliance metric

• Use the four-level approach for diverse taxpayer populations.

Taxpayers have widely varying tax literacy. The adult level serves sophisticated self-filers. The teenager level serves the average taxpayer. The 5-year-old level serves taxpayers with lower literacy or limited English proficiency

• Prepare for IRS AI guidance. The IRS's OPR Alert 2026-19

aligns AI requirements with Circular 230. Readability of AI- generated tax communications should be part of the compliance framework — because incomprehensible communications lead to non- compliance

The bottom line

Tax communications have direct financial consequences. A taxpayer who cannot understand their tax explanation, notice, or filing instruction faces penalties, interest, and audit risk. The IRS advisory panel specifically identified plain-language resources as the path to reducing compliance failures and enforcement burdens.

The tax software and IRS teams that add a readability layer to their AI-generated tax communications will help taxpayers comply correctly the first time. The teams that do not will keep generating professional-grade explanations that tax professionals understand and taxpayers do not — and the enforcement burden will continue to grow.

A tax explanation the taxpayer cannot read is not an explanation. It is a compliance risk. Plain language turns it into information the taxpayer can act on.

Try it: paste any tax explanation, IRS notice, or filing instruction into ELI5 AI and get a plain-English version taxpayers can understand and act on — four reading levels, no account required.
