Or did you receive an email from stating that you efiled a tax return (or that your return was accepted or rejected by the IRS), but you did not file this return? You may be a victim of identity theft and tax fraud, or somebody has filed a return with your data by mistake.

We are committed to helping our clients and other taxpayers protect their data and to promote awareness of identity theft practices. Steps to take if Identity theft occurred to you. 

Did the IRS send you Letter 5701C or 5747C? Details

Review the following sections below for information on how identity thieves target individuals, what you can do to protect yourself from identity theft, and how to report identity theft to the IRS and/or state tax agencies:

What is Identity Theft?

Identity theft is the fraudulent use of an individual's private identifying information to commit fraud for financial gain. Identity thieves seek ways to gather personal information from unsuspecting individuals to commit fraud while the victims are unaware of the acts.

  • Identity theft has seen a rise in recent years of 50% from 2005 to 2010, according to Department of Justice figures. The good news is that in recent years, the IRS Criminal Investigation division helped convict almost 2,000 identity thieves. They also have 1,7000 open investigations
  • You may be a victim of identity theft if you receive a notice or letter from the IRS that states one or more of the following:
  • More than one tax return was filed using your SSN,
  • You owe additional tax, have a refund offset or have had collection actions taken against you for a year you did not file a tax return, and/or
  • IRS records indicate you received wages from an employer.

How Are Identities Stolen?

Identity thieves use various methods to maliciously obtain personal information. One of the most common methods used to obtain electronic information is “phishing.” Phishing is a technique used by identity thieves to gather private and personal information by sending false electronic communications from a seemingly legitimate source. This may take the form of e-mail communications or phone calls from a financial institution such as a bank or a government agency.

Financial institutions and government agencies, as a rule, do not ask you for personal information such as your social security number or password over e-mails and phone calls. For example, if the IRS wants additional information about a tax return you filed, they usually send you a letter in the mail, which includes information on how to contact them if you have questions about the notice.

If a person responds to a phishing e-mail or provides personal information to a caller pretending to be the IRS, they may very well be sending would-be thieves the keys to commit fraud!

Here's some more information on phishing and e-mail scams.

Protect Yourself from Identity Theft

There are a number of measures that individuals such as yourself can take to prevent your identity from being stolen or used fraudulently.

Preventing Phishing

  • Be aware of e-mails and/or phone calls asking for personal information from you (important: the IRS will never initially email or call you about a tax return; they will send you a notice in the mail first)
  • Examine e-mails to see where they are coming from
  • Never provide personal or confidential information to an unverified source. Protect your personal data by keeping it somewhere only you will see it.
  • Contact the financial institution or agency to establish legitimacy of the e-mail or phone call
  • Review bank and credit card statements for any unusual activity
  • Use security software with firewall and anti-virus protections. Make sure the software is always turned on and allows automatic updates.

Preventing Tax Fraud

  • Follow steps above to prevent phishing
  • Carefully choose your efiling or filing partner
  • Audit and examine your own books for any irregularities
  • Be aware of irregular practices, such as keeping two books and the use of social security numbers belonging to the deceased
  • Monitor any communication you receive from the IRS or Tax Agencies
  • Make sure your tax records are secure. If they are electronic, encrypt them with strong passwords. 

Report Identity Theft to the IRS

If you believe you are the victim of identity theft, follow the steps below to report the tax fraud to the IRS:

  1. Visit the Identity Theft Central section at the IRS.
  2. Call the IRS Identity Protection Specialized Unit at 1-800-908-4490 for guidance.
  3. Complete Form 14039-Identity Theft Affidavit to prove that you're the real taxpayer (or on behalf of a deceased spouse or relative whose personal information was used to file a fraudulent tax return). If you're a victim if identity theft and the theft is affecting your tax records, check Box 1 in Section A. However, if you identity was compromised but it was not used on a fraudulent tax return, check Box 2 in Section A (you can also check this box if you had any personal belongings or Social Security cards stolen).
  4. Mail Form 14039 to this address: Internal Revenue Service, Stop C2003, Fresno, CA 93888.
  5. You may also need to file a police report and a complaint with the Federal Trade Commission on their website if you're a victim of tax return fraud.

Important: If you efiled your tax return and the IRS rejected it because your SSN was misused, you will need to paper file your return. Attach Form 14030 and other documentation to your paper return and mail it to the IRS address listed in Step 3.

Report Tax Fraud to Local State Agencies

Generally, each state has either a telephone hotline or an address where an individual can file one's report, if not both. To report income tax fraud, either call a tax hotline or contact the department of taxation via the specified address. Some states require you to fill out a form to mail.
