The 5071C Letter is sent when the IRS detects suspicious activity on your return or suspects someone may be trying to use your Social Security number fraudulently. It's a request for you to confirm your identity before processing your tax return.

Key Features of the 5071C Letter:

• Identity verification request before return processing
• Instructions for online or phone verification
• Secure process to protect against identity theft
• Typically allows 30 days to respond
• May delay refund until verification is complete
