Understanding Your 5071C Letter
This letter tells you that the IRS needs more information from you to process your tax return accurately.
Why are we contacting you?
We received your federal income tax return; however, we need more information from you to process it. The letter you received provides two options for responding to this letter, our secure website or a toll free IRS telephone number. You also have an option for us to telephone you when you provide a faxed copy of the letter you received and a good contact number for us to use. Both options allow you, as the taxpayer, to verify your identity and allow the IRS to continue processing your tax return.
What is involved in this process?
The best way for you to contact us to provide the information needed to process your return is through our identity verification process described below.
What should you do?
- We highly recommend responding through our secure Identity Verification Service website. It's quick and secure. You will need to have a copy of your most recently filed tax return available to complete the entries.
- You can also contact us using the toll free number provided in your letter. You will, again, need to have a copy of your most recently filed tax return available. Both options are available even if you haven't filed a return for this year.
- If you prefer that we call you, please provide your area code and phone number and the hours we may reach you in the space provided in the letter you received and fax it to the number provided.
