Why your tax preparer asks so many questions (and keeps your documents)

Why your tax preparer asks so many questions

If you’ve ever wondered why a tax professional asks detailed questions or requests copies of documents you already provided, there’s a simple reason: federal law requires it.

When a return includes certain credits or filing statuses, the IRS imposes strict “due diligence” rules on paid preparers. These rules exist to protect both you and the preparer from errors, audits, and penalties.

What triggers due diligence

Extra rules apply when a return includes:

• Earned Income Tax Credit (EITC)

• Child Tax Credit / Additional Child Tax Credit

• Credit for Other Dependents

• American Opportunity Tax Credit

• Head of Household filing status

These items are commonly audited, so the IRS requires extra verification.

Why documents must be kept

If a preparer relies on a document to determine your eligibility or calculate a credit, they are legally required to keep a copy. This includes things like:

• School records or tuition statements

• Proof of residency for a child

• Income records

• Support or household expense information

This is not optional and not about distrust. It’s about compliance.

Why you may be asked “obvious” questions

Even if an answer seems clear to you, the IRS standard is based on what a reasonable, well-informed preparer should question. If something appears incomplete, inconsistent, or unusual, the preparer must ask follow-up questions and document your answers.

Skipping questions or guessing answers can invalidate a credit and cause problems later.

How this protects you

Proper due diligence:

• Reduces audit risk

• Helps ensure credits are claimed correctly

• Creates documentation if the IRS ever asks questions

• Prevents denial of credits years later

Why your tax preparer asks so many questions - Bottom line

When your tax preparer asks detailed questions or keeps copies of documents, it’s not bureaucracy—it’s protection. These steps help ensure your return is accurate, defensible, and compliant with IRS rules.

If you ever feel unsure why something is being requested, ask. A good preparer will explain the reason clearly.
