How to Dispute a Penalty From the IRS

Challenge IRS penalties through formal dispute process with proper documentation and deadlines

1. Identify the penalty type and dispute deadline. Check your IRS notice for the penalty code and dispute timeframe. Most penalties allow 30 days from the notice date to dispute. Late filing penalties (FTF) and late payment penalties (FTP) are the most common business penalties, typically 5% and 0.5% per month respectively.
2. Gather documentation for reasonable cause. Compile records showing why the penalty shouldn't apply: bank statements proving timely payment, medical records for illness, correspondence showing IRS processing delays, or natural disaster documentation. The IRS accepts reasonable cause arguments for circumstances beyond your ordinary business care and prudence.
3. Choose your dispute method. Use Form 843 (Claim for Refund) if you already paid the penalty, or write a reasonable cause letter if you haven't paid yet. Include your business EIN, tax period, penalty amount, and specific reasonable cause explanation with supporting documents.
4. Submit your dispute before the deadline. Mail your Form 843 or reasonable cause letter to the address on your penalty notice. Send via certified mail with return receipt. The IRS typically responds within 45-60 days, though complex cases may take longer.
5. Escalate to Appeals if initially denied. Request an appeal within 30 days if your initial dispute is denied. Appeals officers have more discretion than initial reviewers. Include Form 12203 (Request for Appeals Review) and any additional documentation that strengthens your reasonable cause argument.
