How can I protect my identity when filing taxes online?

Use temporary email addresses for tax-related communications, enable two-factor authentication, file directly through IRS.gov or trusted tax software, and never share your SSN via unencrypted email. Monitor your credit reports after filing.

What is tax-related identity theft?

Tax identity theft occurs when someone uses your Social Security Number to file a fraudulent tax return and claim your refund. In 2025, the IRS reported over 1.4 million cases of tax-related identity theft affecting Americans.

Should I use my real email for tax software?

For your primary tax filing account, use a dedicated email you control. For downloading free guides, comparing services, or signing up for newsletters, use a temporary email to prevent spam and potential phishing attacks.

How do scammers get tax information?

Scammers obtain tax information through phishing emails, data breaches, dark web purchases, social engineering, and malware. Using temporary emails for non-essential signups reduces your exposure to these attack vectors.

Identity Protection for Online Tax Filing in 2026

The Growing Threat of Tax Identity Theft

Tax-related identity theft remains one of the most damaging forms of fraud affecting Americans. Criminals file fraudulent returns using stolen Social Security Numbers, claiming refunds before legitimate taxpayers can file. In 2025, the IRS reported over $5.7 billion in attempted tax fraud, with 1.4 million Americans directly impacted.

Red Flags: Signs Your Identity May Be Compromised

• IRS notice that more than one tax return was filed using your SSN
• IRS records show wages from an employer you don't recognize
• Your e-filed return is rejected as a duplicate
• You receive a tax transcript you didn't request
• Unexpected IRS notices about collections or refund offsets

Essential Protection Strategies

1. Get an IRS Identity Protection PIN

The IRS IP PIN is a six-digit number that prevents someone else from filing a tax return using your SSN. Once enrolled, the IRS will reject any return without your correct IP PIN. This single step prevents 99% of tax identity theft.

How to Get Your IP PIN:

1. Visit IRS.gov/ippin
2. Create or log into your ID.me account
3. Verify your identity
4. Receive your unique 6-digit IP PIN
5. Use it on all future tax returns

2. Secure Your Email Communications

Email is a primary attack vector for tax scammers. They send phishing emails impersonating the IRS, tax software companies, and CPAs. Protect yourself by:

Use temporary email for tax research: When downloading tax guides, comparing software, or exploring services, use a temporary email from Temp Postalto avoid spam and phishing attempts
Dedicated tax email: Create a separate email account solely for tax-related communications with your CPA and official tax software
Enable 2FA: Two-factor authentication on all tax-related accounts
Verify senders: The IRS never initiates contact via email—any unsolicited tax email is a scam

3. Protect Your Social Security Number

SSN Protection Best Practices:

✓ DO:

• Keep your Social Security card in a secure location
• Shred documents containing your SSN
• Only share SSN when absolutely necessary
• Verify the legitimacy of requests for your SSN

✗ DON'T:

• Carry your Social Security card in your wallet
• Share your SSN via email or text
• Post documents with visible SSN online
• Give your SSN to unsolicited callers

4. File Early

Filing your tax return early is one of the most effective ways to prevent fraud. Once your legitimate return is processed, the IRS will reject duplicate filings. File as soon as you have all necessary documents—typically by late January for W-2 employees.

5. Use Trusted Tax Software

Only use tax software from established, reputable companies. Before signing up:

Verify the company's legitimacy through the IRS Free File program
Check for secure HTTPS connections and valid SSL certificates
Read reviews from verified users
Use a temporary email for trial accounts to avoid marketing spam

What to Do If You're a Victim

Immediate Steps If Identity Is Compromised:

1. File IRS Form 14039 - Identity Theft Affidavit. Submit online at IdentityTheft.gov or mail to the IRS
2. Respond to IRS notices - If you receive an IRS notice, respond immediately using the phone number or address provided
3. File a police report - Document the crime with local law enforcement
4. Place a fraud alert - Contact one of the three credit bureaus to place a fraud alert on your credit reports
5. Request a credit freeze - Prevents new accounts from being opened in your name
6. Get your IP PIN - Request an Identity Protection PIN to prevent future fraudulent filings
