Different expert here - My name is ***** ***** I disagree with the course of action you should take regarding the 5071C letter you received from the IRS.
As you mentioned in your original question, the IRS already suspects you may be/are the victim of identity theft. That is the reason you received the 5071C letter.
The following link contains excellent information regarding the 5071C letter:
As you can see from the information in the link, the following is the action you should take as soon as possible:
•Use the secure Identity Verification Service website idverify.irs.gov. It's quick and secure. You should have available a copy of your prior year tax return
and your current year tax return, if you filed one, including supporting documents.
•If you cannot use the Idverify website, you can call the IRS using the toll-free Identity Verification telephone number provided in your letter. Again, you should have available a copy of your prior year tax return and your current year tax return, if you filed one, including supporting documents.
•If you did not file the return in question, you can use either option to notify the IRS.
My preference would be to call the IRS at the number on your 5071C letter since the integrity of some of the IRS website was breached several weeks ago.
As to Ideal Tax Solutions, ignore and delete the email you received from them. It sounds like a "phishing" email. You do not file a tax return, do not owe any taxes, and have no need of their services.
Please let me know if you require further information or clarification.
Thank you and best regards,
