Every tax season brings new compliance requirements, IRS updates, and regulatory changes that tax professionals must carefully follow. Among the most important rules affecting refund processing is the Protecting Americans from Tax Hikes (PATH) Act. This regulation continues to influence how the Internal Revenue Service (IRS) verifies certain tax returns and issues refunds.

For the 2026 filing season, the path act 2026 remains a critical regulation that CPA firms, tax preparers, and accounting professionals must understand. The law primarily affects tax returns claiming refundable credits such as the Earned Income Tax Credit (EITC) and the Additional Child Tax Credit (ACTC).

Because these credits can generate large refunds, the IRS applies additional verification procedures before releasing payments. For tax professionals, understanding these rules is essential for ensuring compliance, managing client expectations, and maintaining efficient tax preparation processes.

In this guide, we’ll explore what tax professionals should know about the PATH Act 2026 and how it impacts tax preparation workflows.

Understanding the Purpose of the PATH Act

The PATH Act was introduced to strengthen the integrity of the U.S. tax system by reducing fraudulent refund claims. Refundable tax credits such as EITC and ACTC are designed to support working families and lower-income taxpayers. However, these credits have historically been targeted by fraud schemes.

Before the implementation of the PATH Act, some fraudulent tax returns were processed and refunded before the IRS could verify the information. Criminals sometimes filed returns using stolen identities or inaccurate income data to claim large refunds.

To address this issue, the PATH Act introduced a mandatory delay in refund processing for returns claiming certain refundable credits. This delay allows the IRS to verify income information and detect fraudulent filings before releasing refunds.

Refund Delay Rules Under PATH Act 2026

One of the most important provisions of the PATH Act is the refund delay rule.

Under this regulation, the IRS must delay issuing refunds for tax returns claiming:

• Earned Income Tax Credit (EITC)

• Additional Child Tax Credit (ACTC)

These refunds cannot be issued before mid-February, regardless of when the taxpayer files their return.

The delay applies to the entire refund amount, not just the portion related to the credit.

For example, if a taxpayer expects a $3,500 refund and $1,200 of that amount comes from EITC, the IRS will delay the full $3,500 refund until the verification period ends.

This rule is designed to ensure that refundable credits are claimed accurately.

Why the PATH Act Matters for Tax Professionals

CPA firms and tax preparers play an important role in ensuring that tax returns comply with IRS regulations. Because the PATH Act directly affects refund timelines, tax professionals must understand how it impacts their clients.

Tax professionals should be prepared to:

• Explain refund delays to clients who claim EITC or ACTC

• Verify eligibility for refundable tax credits

• Ensure accurate income reporting

• Maintain compliance with IRS due diligence requirements

Proper understanding of these rules helps tax professionals avoid compliance issues and provide reliable guidance to clients.

Due Diligence Requirements for Tax Preparers

The IRS requires tax preparers to follow strict due diligence rules when preparing returns that claim refundable credits.

These responsibilities include verifying:

• Income eligibility for the credit

• Filing status accuracy

• Dependent qualifications

• Residency requirements for qualifying children

Tax professionals must also maintain documentation supporting these claims.

Failure to follow due diligence requirements may result in penalties for tax preparers. Therefore, careful documentation and verification are essential when preparing these returns.

How the IRS Verifies Refund Claims

The PATH Act gives the IRS additional time to verify tax return information before issuing refunds.

During this verification period, the IRS may perform several checks, including:

• Comparing reported income with employer-submitted wage data

• Confirming taxpayer identity information

• Reviewing dependent eligibility for tax credits

• Running fraud detection algorithms

Employers submit wage information through Form W-2 reporting, which allows the IRS to cross-check the taxpayer’s reported income.

If inconsistencies appear, the IRS may delay the refund further while reviewing the return.

Impact on Tax Season Workflows

The PATH Act also influences how CPA firms manage their tax season operations.

Because refunds are delayed for certain returns, clients often contact tax preparers asking why their refunds have not yet been issued.

To manage these situations effectively, many firms provide early communication about PATH Act refund rules.

For example, tax professionals may explain to clients that:

• Filing early does not bypass the refund delay

• The IRS must complete verification checks before issuing refunds

• Most refunds are released between late February and early March

Providing this information early helps prevent confusion and reduces the number of client inquiries during the tax season.

Real Example of PATH Act Impact

Consider a taxpayer who files their federal return on January 23, 2026.

Taxpayer profile:

• Filing status: Head of Household

• Annual income: $34,000

• Two qualifying children

• Eligible for Earned Income Tax Credit

The taxpayer expects a refund of approximately $4,000.

Even though the return is filed early, the IRS must delay the refund under PATH Act rules. During the verification process, the IRS confirms wage information reported by the employer and verifies eligibility for the tax credit.

After completing these checks, the refund is issued in late February.

This process ensures the refund claim is legitimate before payment is released.

Best Practices for Tax Professionals

To ensure smooth tax season operations, tax professionals should follow several best practices related to PATH Act compliance.

Educate Clients Early

Inform clients about refund delays before filing their tax returns. Clear communication helps manage expectations.

Verify Documentation Carefully

Ensure that income records, dependent information, and eligibility documentation are accurate.

Use Professional Tax Software

Modern tax preparation software includes compliance checks that help identify potential issues with refundable credit claims.

Monitor IRS Refund Tracking Tools

The IRS provides tools such as Where’s My Refund, which allows taxpayers and tax professionals to track refund processing status.

Final Thoughts

The PATH Act 2026 continues to play a vital role in improving tax compliance and preventing fraudulent refund claims. By delaying refunds related to certain tax credits, the IRS gains time to verify income information and confirm taxpayer eligibility.

For CPA firms and tax professionals, understanding the rules and requirements associated with the PATH Act is essential during the tax season. Accurate documentation, proper due diligence, and clear client communication can help ensure compliance while providing a better experience for taxpayers.

As tax regulations continue to evolve, staying informed about laws like the PATH Act helps tax professionals deliver more reliable, compliant, and efficient tax services.
