Understanding Your 5071C Letter
This letter tells you that the IRS needs more information to verify your identity in order to process your tax return accurately. The contact information below is only for taxpayers who received Letter 5071C.
Why are we contacting you?
We received your federal income tax return; however, in order to process it, we need more information to verify your identity. The letter you received provides two options for responding. Both options enable you to verify your identity with us so we can continue processing your tax return.
This contact information is only for taxpayers who received Letter 5071C. The toll-free number and website are for identity verification only. No other tax-related information, including refund status, is available.
What is involved in this process?
We will continue processing your tax return once we verify your identity. Follow the identity verification described under "What should you do?" below to provide us with the necessary information.
What should you do?
- Use our secure Identity Verification Service website idverify.irs.gov. It's quick and secure. To complete the entries, you will need to have a copy of your prior year tax return and your most recently filed tax return.
- If you cannot use the Idverify website, you can call us using the toll-free Identity Verification telephone number provided in your letter. Again, you will need to have a copy of your prior year tax return and your most recently filed tax return.
- If you did not file the return in question, you can use either option to notify us.
