What to stress

  • The professional was CREDENTIALED (CPA, EA, Attorney) - not just a "tax preparer"
  • You provided COMPLETE AND ACCURATE information
  • You had NO REASON TO DOUBT the advice given
  • Your prior relationship with the professional was problem-free
  • You ACTED PROMPTLY once you discovered the error
  • The advice was about a TAX MATTER, not just a procedural deadline

What not to say

  • "My tax preparer filed late" - filing deadlines are YOUR responsibility per IRS
  • "I gave them all my documents" without verifying they were complete
  • Using an uncredentialed preparer (paid preparers are NOT the same as CPAs)
  • "I assumed they would handle everything"
  • Relying on advice about a non-tax matter (e.g., mailing procedures)
  • "Everyone uses this preparer" - you need to show YOUR due diligence

Common reasons the IRS says no

  • Used uncredentialed preparer (just PTIN, no CPA/EA/Attorney)
  • Advice was about filing deadline, not substantive tax matter
  • Taxpayer did not provide complete information
  • Taxpayer should have known better (e.g., sophisticated taxpayer)
  • No evidence of the advice received
  • Prior problems with same professional were ignored

Questions about this template

Usually not. Filing and paying on time is your own duty, even if you hire someone. Relying on advice works best when the advice was on a technical question, such as whether a return was required.

The engagement letter, the advice itself (emails or letters), and a record of what you gave the professional.

Yes. Give their name, credentials and the date of the advice, so the IRS can judge whether relying on it was reasonable.
