IRS Form 14039 Instructions

Let’s start with step by step guidance on completing your identity theft affidavit.

How do I complete IRS Form 14039?

This two-page tax form is fairly straightforward. Form 14039 contains six sections, which we’ll cover one at a time, starting with Section A.

Section A: Type of situation you are reporting

Section A simply informs the IRS why you are submitting the identity theft affidavit. You can choose from the following options:

• You are filing on your own behalf
• You are filing in response to an IRS notice or letter
  • If you select this box, you must provide the IRS notice or IRS letter number(s) on the provided line
  • You should also check Box 1 in Section B and follow the special mailing or faxing instructions
• You are filing on behalf of a dependent
  • Complete the entire form
  • Do not use this form if the dependent’s identity was misused by a parent or relative filing a tax return
• You are filing on behalf of another person who is not a dependent
  • Can be living or deceased
  • Complete the entire form

Check the box that pertains to your situation and move on to Section B.

Section B: How you are impacted

Check all boxes that apply to the identity theft victim (see Section C, below).

• I know that someone used my information to fraudulently file a tax return
• Someone fraudulently claimed me or my dependent as their own dependent on a tax return
• Someone fraudulently used my SSN or individual taxpayer identification number (ITIN) for employment purposes
• I have been a victim of identity theft

Additionally, use the available space to provide a written explanation on this issue, to include:

• How this issue has impacted your tax account
• When you became aware of the issue (with relevant dates)

If required, attach additional pages to the form.

Section C: Contact information of the identity theft victim

In Section C, provide the victim’s name and contact information. This should include:

• Victim’s name
• Social Security number or ITIN
• Mailing address, to include city, state, and zip code
• Address used on last tax return (if different from current mailing address)
• Telephone number and best time to call
• Preferred language

Section D: Tax account information

In Section D, check the box if you were not required to file an income tax return, or if you filed a non-filer return.

If you’ve previously filed a tax return, list the following:

• Name(s) used on the last tax return
• The year that you last filed a tax return
• The tax year(s) that you believe were impacted
  • If you do not know, enter ‘Unknown’

Section E: Penalty of perjury statement and signature

Section E contains the sworn signature of the filer, under penalty of perjury. Only sign this Form 14039 if you believe this information is true, correct, complete, and made in good faith.

Section F: Representative, conservator, parent, or guardian information

Only complete Section F if you are submitting Form 14039 on someone’s behalf.

In that case, check only one of the following boxes:

Taxpayer is deceased, and I am the surviving spouse

You do not need to attach any documents. This includes the taxpayer’s death certificate.

Taxpayer is deceased and I’m the personal representative or court-appointed representative

Attach a copy of the court certificate documenting your appointment as the taxpayer’s personal representative.

Taxpayer is deceased, and a personal representative has not yet been appointed

Attach a copy of the death certificate or a formal notification letter from a government office regarding the taxpayer’s death.

Also, indicate your relationship to the deceased taxpayer:

• Child
• Parent or legal guardian
• Other

Taxpayer is unable to complete this form

This can be for one of two reasons:

• You are the appointed conservator, or
• You have been authorized to act on the taxpayer’s behalf on IRS Form 2848

Attach one of the following:

• Copy of the appointment letter designating you as conservator
• Copy of the IRS Form 2848, Power of Attorney authorization

If you have an IRS-issued centralized authorization file (CAF) number, enter it here.

The person is my dependent

Checking this box indicates that you are an authorized representative to file a legal document on behalf of the dependent. If this is true, check the appropriate box to indicate your relationship:

• Parent or legal guardian
• Power of attorney
• Fiduciary per IRS Form 56, Notice of Fiduciary Relationship
• Other (complete the line)

After checking the appropriate box, enter the personal representative’s information, to include:

• Name
• Current mailing address
  • Including city, state, and zip code
• Contact telephone number

What is tax identity theft?

According to the IRS website, tax identity theft occurs when an identity thief “steals your personal information to commit tax fraud.” The Government Accountability Office states that there are two basic types of tax identity theft:

• Employment fraud
• Tax refund fraud

Employment fraud occurs when someone stales a taxpayer’s identity to secure employment under that person’s identity.

Tax refund fraud occurs when someone steals taxpayer information to file a fraudulent return to claim a false tax refund. In these cases, the IRS sends the fraudulent refunds to the scammer’s bank account while the identity theft victims face potential audits for the suspicious return.

How does tax identity theft occur?

Tax identity theft may occur through a variety of means:

• Data breach: If you’re the victim of a data breach, you should keep in touch with the company who is responsible for your personal information to see what identity theft services they might be providing
• Identity theft scams: Identity theft scams usually target a specific individual by convincing that person to give the scammer certain personal information like the taxpayer’s Social Security number, bank account numbers, or access to certain cash applications like Venmo. Examples of identity theft scams might include:
  • Email phishing scams
  • Text message scams
  • Phone scams

In identity theft cases, victims might be less willing to report the incident if they’ve unwittingly given the tax scammers enough information to claim a fraudulent refund.

While victims of tax-related identity theft cannot prevent data breaches, they can be on the look out for identity theft scams and avoid falling for them. Here are some warning signs that you might be a victim of tax identity theft.

What are the warning signs of tax identity theft?

Below are some of the more common warning signs that someone is using your tax information to file fraudulent tax returns:

• You get a letter from the IRS inquiring about a suspicious tax return that you did not file
• You can’t file an electronic tax return because of a duplicate Social Security number
• You get a tax transcript in the mail that you did not request
• You get an IRS notice that an online account has been created in your name when you know that you did not create an online account
• You get an IRS notice that your existing online account has been accessed or disabled when you took no action
• You get an IRS notice for one of the following:
  • You owe additional taxes
  • There is a tax refund offset against you
  • You have had collection actions taken against you for a year during which you did not file a tax return
• IRS records indicate you received wages or other income from an employer you didn’t work for
• You’ve been assigned an Employer Identification Number but you did not request an EIN

How long does the IRS take to investigate tax identity theft?

The IRS website contains a lot of useful information for victims of tax-related identity theft. This includes ways that taxpayers may remain informed once they inform the IRS of a fraudulent tax return or send an IRS identity theft affidavit.

According to the IRS identity theft victim assistance page, the IRS reports that tax identity cases are usually resolved within 120 days. However, due to the pandemic, IRS records indicate a rise in identity theft cases which have increased the lead time to about 360 days, on average.
