The LTR 531 is follow-up correspondence in an ongoing examination. You've already been contacted about an audit, and now the examiner needs something more. It could be additional documentation, clarification on items you already provided, or notification of expanded scope.
Why You're Getting Follow-Up
Audits are iterative. The examiner reviews your initial documents, identifies questions, and requests more information. Common reasons for the LTR 531 include documents that were incomplete or illegible, new issues identified during the review of initial documents, requests for explanations of specific transactions, and requests for records from third parties (bank statements, vendor invoices, client contracts).
An expanded scope means the auditor found something in the initial review that raised questions about other areas of your return. If the original audit focused on Schedule C expenses and the auditor noticed unreported income, they may expand the examination to include income verification.
How to Respond
Treat the LTR 531 with the same urgency as the original audit contact. Respond by the deadline with complete documentation. If you need more time, contact the examiner before the deadline to request an extension.
Don't ignore follow-up requests. If the examiner doesn't get the information they need, they'll propose changes based on what they have. Without your documentation, those changes will be entirely unfavorable.
Representation
If the audit scope is expanding or the requests are getting more complex, this is a good time to bring in professional representation if you haven't already. An expanding audit is a sign that the examiner found issues, and the follow-up is aimed at quantifying the impact.
