Due diligence in tax preparation is the detailed and careful effort required to ensure all tax information is accurate and complete before submitting a tax return. This process involves gathering necessary documents, verifying income and deduction claims, asking clarifying questions, and properly documenting the preparer’s or taxpayer’s work. The practice is essential to prevent mistakes, avoid IRS penalties, and reduce the risk of audits.

Importance of Due Diligence in Tax Preparation

Due diligence became a formal requirement largely due to concerns over fraudulent claims and abusive tax refund practices, especially involving refundable tax credits like the Earned Income Tax Credit (EITC), Child Tax Credit (CTC), and American Opportunity Tax Credit (AOTC). The IRS enforces due diligence rules primarily on paid tax preparers, requiring them to follow strict procedures and document their compliance using IRS Form 8867.

By practicing due diligence, preparers and taxpayers help maintain the integrity of the tax system, ensuring government funds are properly distributed and that taxpayers are fairly treated.

Key Elements of Due Diligence

  • Comprehensive Information Gathering: Collect all relevant tax documents such as W-2s, 1099s, receipts, and records supporting income and deductions.
  • Verification and Cross-Checking: Confirm that reported income, deductions, and credits are supported by documentation and consistent with IRS regulations.
  • Eligibility Questions: Ask detailed questions to verify qualification for specific credits, for example, residency status of children for the Child Tax Credit.
  • Recordkeeping: Maintain detailed documentation of the verification process and questions asked, as required by IRS guidelines.
  • Critical Evaluation: Do not rely solely on client information if inconsistencies appear—investigate and clarify to ensure accuracy.
  • Use of IRS Tools and Checklists: Utilize IRS resources designed to guide preparers in meeting their due diligence obligations.

Who Must Comply with Due Diligence Rules?

  • Paid Tax Preparers: Professionals are legally required to meet due diligence standards and submit Form 8867 for returns claiming certain credits.
  • Taxpayers Preparing Their Own Returns: While not mandated, taxpayers benefit from applying the same careful checks to avoid errors.
  • Small Business Owners and Freelancers: Complex returns demand thoroughness to capitalize on eligible deductions and credits without triggering audits.
  • The IRS: Relies on due diligence from preparers and taxpayers to minimize fraud and improper payments.

Practical Examples

  • A paid preparer questions a client’s eligibility for a large Earned Income Tax Credit when income documents appear inconsistent, requesting additional proof like pay stubs before filing.
  • A self-preparing taxpayer uses reliable tax software that prompts for details and documentation when claiming childcare credits, reducing the chance of error.
  • A preparer refusing to claim a questionable home office deduction without sufficient verification of the workspace usage, ensuring compliance.

Tips for Practicing Due Diligence

  • Organize all tax-related records securely and keep them accessible.
  • When preparing returns or working with clients, ask specific questions about eligibility for credits and deductions.
  • Use up-to-date, reliable tax software with built-in accuracy checks.
  • Stay informed about tax law changes that may affect credits and deductions.
  • Document all verification steps clearly, whether working professionally or on your own taxes.
  • Avoid rushing tax preparation to reduce mistakes.

Common Mistakes to Avoid

  • Treating due diligence as optional or overlooking it, especially by paid preparers.
  • Accepting client information without verification, which can lead to incorrect returns or fraud.
  • Failing to maintain proper documentation of due diligence efforts, risking harsher IRS penalties.
  • Misunderstanding credit eligibility rules, such as residency requirements for dependents claiming the Child Tax Credit.
