Why this letter deserves prompt attention
Letter 3176C says the IRS considers a return position frivolous. The warning can lead to a $5,000 penalty; the IRS describes a $10,000 amount for a jointly filed return.
Read the requested correction
The letter may request an amended return, withdrawal of a position, a signed declaration, or supporting records. Do not assume every recipient should send the same response. IRS guidance calls for a response within 30 days of the letter date; contact the IRS within that period if you need an extension.
Prepare before responding
Compare the actual filed return with the copy your preparer gave you. Identify the disputed credit or withholding entry and gather its supporting records. Have a qualified tax professional review the specific issue before signing a correction or withdrawal. If you did not file the return, tell the IRS that in your response.
Keep a complete response copy and evidence of delivery. Avoid relying on a preparer's verbal assurance that the letter will resolve itself.
