Tax Identity Theft: 6 Practical Ways To Prevent It
Learn how tax identity theft happens, how to spot it early, and what to do right away if scammers target your tax refund.
Tax identity theft blends two stressful topics: taxes and identity fraud. When criminals get enough of your personal information to file a fake tax return in your name, they can steal your refund, disrupt your finances, and trigger a long and frustrating cleanup process.
This guide explains how tax identity theft works, who is most at risk, how to lower your chances of becoming a victim, and what to do immediately if you suspect a problem.
What Is Tax Identity Theft?
Tax identity theft happens when someone uses your Social Security number (SSN) or other taxpayer identification number to file a tax return or claim a tax benefit that belongs to you. In most cases the scammer aims to grab a fraudulent tax refund before you file your own legitimate return.
| Type of misuse | How thieves benefit | How it can affect you |
|---|---|---|
| Filing a fake refund return | Claiming a large, fraudulent refund using your SSN | Your real return is rejected or your refund is delayed |
| Claiming dependents | Using your children or relatives to boost a fake refund | You cannot claim the dependents or credits you are entitled to |
| Employment-related identity theft | Using your SSN to get a job or pass a background check | IRS records may show income you never received and tax you never owed |
Because tax returns are filed only once a year, thieves try to move quickly during filing season. Filing before you do is a core part of the scam.
How Criminals Get Your Tax Information
Scammers rarely need your full tax file to do damage. A name, date of birth, and SSN are often enough. They collect those details in several ways:
- Data breaches at employers, health providers, schools, or financial institutions that expose SSNs and other identifiers.
- Phishing messages by phone, text, or email pretending to be from the IRS, a tax software company, or your bank, asking you to “verify” information or click a link.
- Weak online security, such as reused passwords, outdated software, or insecure Wi-Fi, that allows hackers to access your accounts.
- Paper theft, including stealing mail that contains W-2s, 1099s, or tax transcripts, or digging through trash that was not shredded.
- Insider abuse by someone you hired or trusted with sensitive documents, such as an unscrupulous tax preparer.

Who Is Most at Risk?
Anyone with a tax identity number can be targeted, but some groups draw more attention from scammers:
- People expecting large refunds based on income credits, child credits, or other refundable benefits.
- Older adults, who may be more heavily targeted by phone and mail scams.
- Students and young adults, who are building credit and may not monitor their records closely.
- Victims of previous data breaches, whose information is already circulating on criminal marketplaces.
- Deceased individuals and their families, if final returns are delayed and personal data becomes exposed.
Early Warning Signs of Tax Identity Theft
Most people first learn about tax identity theft at tax time, when they interact with the IRS. Be alert for the following red flags:
- Your electronically filed return is rejected because a return with your SSN is already on file.
- You receive an IRS notice about a tax return you did not file.
- The IRS notifies you that an online account in your name was created or accessed and you did not do it.
- IRS records show wages from an employer you do not recognize.
- You receive a notice that you owe additional tax, have a refund offset, or are facing collection for a year when you did not file.
- You receive a tax transcript or refund check you did not request.
These signs do not always mean fraud, but they are serious enough that you should respond quickly and directly with the IRS, not with the sender of any suspicious message.
Practical Ways to Prevent Tax Identity Theft
No single step can guarantee absolute protection, but combining multiple defenses sharply reduces your risk. Revisit these habits every tax season.
1. Guard Your Social Security Number
Your SSN is the key to tax-related identity theft. Treat it as confidential information at all times.
- Avoid carrying your Social Security card in your wallet unless you truly need it.
- Ask why your SSN is needed before providing it; in many cases another identifier is enough.
- Do not send your SSN or full tax forms by email or unencrypted text.
- When discarding old tax records, shred them rather than tossing them intact.
2. File Your Tax Return Early
Filing as soon as you have all required documents can help cut off criminals who plan to submit a fake return first.
- Collect W-2s, 1099s, and other forms promptly and schedule time to file.
- If you expect delays, keep monitoring mail and online IRS notices so you spot any suspicious activity quickly.
3. Use Secure Technology When You File
If you prepare or file taxes online, your digital security matters as much as the numbers on your forms.
- Use a private, password-protected home network, not public Wi-Fi, for tax filing or financial activity.
- Ensure security software, operating systems, and browsers are updated with the latest patches.
- Enable multi-factor authentication on your tax software and financial accounts where available.
- Look for secure website indicators (such as “https” and your browser’s lock symbol) before entering sensitive information.
4. Choose Tax Preparers Carefully
If you hire someone to handle your taxes, that person gains access to detailed financial and personal data. Research them thoroughly before you hand anything over.
- Check their professional credentials and whether they have a valid Preparer Tax Identification Number (PTIN) with the IRS.
- Look for disciplinary history via state boards or professional organizations, if applicable.
- Avoid preparers who guarantee huge refunds or who base their fees on a percentage of your refund.
- Make sure they give you a copy of your return and are willing to sign it with their PTIN.
5. Monitor Your Credit and Financial Accounts
Tax identity theft may show up alongside other forms of identity misuse, like new credit accounts or unexplained transactions.
- Order free credit reports regularly to look for unfamiliar accounts or inquiries.
- Review bank and credit card statements for small test charges and report anything suspicious right away.
- Consider placing a free fraud alert or credit freeze with the major credit bureaus if you believe your information was exposed.
6. Consider an Identity Protection PIN (IP PIN)
An Identity Protection PIN (IP PIN) from the IRS is a six-digit code that helps prevent someone else from filing a federal tax return using your SSN.
- Once you are enrolled, the IRS will accept e-filed returns for your SSN only if the correct IP PIN is included.
- IP PINs are issued annually and can be obtained through the IRS online tools after identity verification.
- Keep your IP PIN confidential and store it separately from the copy of your tax return.
Step-by-Step: What to Do If You Suspect Tax Identity Theft
If you think someone has filed a return using your information—or the IRS tells you so—acting quickly can limit the damage.
1. Respond Directly to Official IRS Notices
- Read any IRS letter or notice carefully to understand what the agency is asking.
- Use the contact information in the notice itself or from the official IRS website; do not rely on numbers or links in unsolicited emails or texts.
- Follow the instructions for confirming your identity or disputing the information the IRS has on file.
2. File an Identity Theft Affidavit (Form 14039)
If the IRS indicates that you may be a victim of tax-related identity theft, you may be asked to submit Form 14039, Identity Theft Affidavit.
- Describe the suspected misuse of your SSN and provide any documentation you have.
- Mail or fax the form as directed by the IRS or include it with your paper tax return if instructed.
- Once your case is processed, the IRS may issue you an IP PIN to use for future filings.
3. Continue to File Your Return
Even if someone else filed a fraudulent return in your name, you still need to file your legitimate tax return.
- Follow IRS guidance, which may require you to file a paper return instead of e-filing.
- Include copies of IRS notices and your Identity Theft Affidavit if recommended.
4. Report and Contain the Broader Identity Theft
Tax identity theft is often just one symptom of a broader identity theft problem. Take these steps to protect yourself more generally:
- Visit the federal identity theft assistance website to create a personalized recovery plan and report the crime.
- Notify your financial institutions and close or secure any affected accounts.
- Place a fraud alert or credit freeze with the major credit bureaus to limit new credit in your name.
- Change passwords and enable multi-factor authentication on email and financial logins.
Long-Term Recovery and Follow-Up
Cleaning up tax identity theft can take time. Staying organized and patient can make the process more manageable.
- Keep detailed records of calls, letters, and forms you send or receive, including dates and reference numbers.
- Monitor IRS communications in case additional verification is needed in future years.
- Review your credit reports periodically to ensure no new fraudulent accounts appear.
- Maintain security habits—updated devices, strong passwords, and cautious data sharing—to prevent another incident.
While tax identity theft can be unsettling, most people are able to resolve their cases and restore their records by working closely with the IRS and following identity theft recovery guidance.
Frequently Asked Questions about Tax Identity Theft
Q: How is tax identity theft different from regular identity theft?
Tax identity theft specifically involves the use of your SSN or taxpayer identification number to file a tax return or claim a tax benefit, usually to steal a refund. Other identity theft may focus on opening credit cards, taking out loans, or making purchases in your name without necessarily involving your tax records.
Q: Does the IRS ever contact people by email, text, or social media?
The IRS typically initiates contact about individual tax accounts by regular mail, not by email, text message, or social media direct message. Messages that demand immediate payment or sensitive information through those channels are strong signs of a scam.
Q: If I use a tax software program, am I fully protected from tax identity theft?
Tax software can help by encrypting your data and offering multi-factor authentication, but it cannot eliminate risk entirely. You still need to use strong, unique passwords, avoid public Wi-Fi, keep your devices updated, and watch for phishing attempts that try to steal your login information.
Q: Should I get an Identity Protection PIN even if I have not been a victim?
The IRS allows many taxpayers to voluntarily obtain an IP PIN as an extra layer of protection. If you are comfortable verifying your identity through IRS systems and committed to safeguarding the PIN each year, it can be a useful defensive tool against fraudulent returns filed with your SSN.
Q: How long does it take to resolve a tax identity theft case?
Resolution time varies. The IRS must investigate the fraudulent filing, correct your records, and ensure that your legitimate return is processed accurately. This can take several months, but responding quickly to IRS notices, submitting requested documents promptly, and following recovery guidance can help keep the process moving.
