Important Update

TY2026 expands the IRS’s ability to correct certain errors involving education credits when required identification information is missing or incorrect. Preparers should carefully review documentation before filing.

Learning at a Glance

What changed?

Congress expanded the IRS’s math error authority for certain education credit requirements.

Primary focus

Education credits may be adjusted when required taxpayer or educational institution identification information is missing or incorrect.

Best practice

Verify identification numbers and supporting documents before filing the return.

Understanding IRS Math Error Authority

The IRS has long been permitted to correct certain mathematical and clerical mistakes without conducting a traditional audit. Under TY2026 law changes, that authority expands in specific situations involving education credit requirements.

For tax preparers, the practical lesson is simple: review identification numbers and supporting documents carefully before filing. Small errors or missing information can delay processing or result in IRS adjustments.

What's New

What’s New: Expanded Authority for Certain Education Credit Errors

Beginning with TY2026, Congress expanded the IRS’s authority to correct certain education credit issues when required identifying information is missing or incorrect. This change emphasizes accurate documentation and careful return preparation.

Key Takeaway

Key Takeaway:
Careful verification of taxpayer information and supporting documents helps reduce avoidable IRS adjustments and improves return accuracy.

Attention Please

Attention Please: Math Error Authority Is Not an Audit

An IRS math error adjustment is different from a traditional examination. In certain situations authorized by law, the IRS may correct specific items on a return without conducting a full audit. Tax preparers should understand these rules and help reduce avoidable corrections by filing complete and accurate returns.

Example

Example:
Jasmine claims an education credit but accidentally enters an incorrect identifying number for the eligible student. Because required information is inaccurate, the IRS may adjust the return under its expanded math error authority rather than processing the credit as filed.

Did You Know

Did You Know?
Many IRS adjustments can be prevented by carefully reviewing identification numbers and comparing them with the taxpayer’s source documents before filing the return.

Preparer Checklist

Verify taxpayer and student identification numbers from source documents.

Review Forms 1098-T and other education records for completeness.

Double-check entries before transmitting the return electronically.

Maintain documentation supporting any education credit claimed.

Practitioner Tip

If a taxpayer later receives an IRS notice adjusting a return, compare the notice with the filed return and supporting records. When questions remain, consult the applicable IRS instructions and current guidance before advising the taxpayer.

Common Mistake

A common mistake is assuming that every IRS adjustment results from an audit. In reality, Congress has authorized the IRS to correct certain mathematical and clerical errors, including specific situations involving education credit requirements, without conducting a traditional examination.
