How to spot fake W-2 forms

Fake W-2 forms have been on the rise since the pandemic in 2020. Governments worldwide began distributing financial aid and unemployment benefits to help citizens manage during the crisis.

However, in the U.S., this approach proved costly. Approximately 10% of pandemic unemployment benefits—an estimated $87.2 billion—were improperly issued.

Organized crime rings and thieves primarily used fake W-2 forms to apply for financial aid during the pandemic.  

Now, in 2025, this isn’t just a warning for the US government.

It’s a wake-up call for lenders, employers, and real estate agencies, as fake W-2 form scams can be easily committed by fraudsters using online editing tools and template farms.

This makes detecting document fraud in W-2 forms particularly challenging.

Read on the learn what W-2 forms are, why they're important, how they're being forged, how to identify a fake W-2, and how AI-powered verification solutions can help spot them automatically.

What is a W-2 form?

A W-2 form, also known as a Wage and Tax Statement, is a document provided by an employer that outlines an employee’s income, taxes withheld from their paycheck, and any benefits received during the fiscal year. 

It typically includes:

• Employer Identification Number (EIN)

• Employer's State ID number

• Employee’s income from the last year

• Taxes withheld including: federal income tax, Social Security tax, deductions, etc.

• Bonuses, tips, and other forms of salary compensation

These details are important for validating the employment history of job candidates or verifying the income of loan applicants and potential tenants.

Why are W-2 forms important? 

Employers use W-2 forms to report Federal Insurance Contributions Act (FICA) taxes and classify employees into full-time workers or 1099s contractors. On the other hand, employees use them to report their income, file federal taxes, and provide proof of income in verification processes.

Here’s a closer look on how W-2 forms serve as a proof of income:

• Loan underwriting. Lenders use W-2 forms to verify an applicant’s creditworthiness during the underwriting process. This helps them manage credit risk and minimize their exposure to potential defaults.

• Tenant screening. W-2 forms provide information for real estate managers and homeowners to select reliable tenants with steady jobs and consistent income, reducing the risk of unpaid rent and tenant delinquency.

• Employment screening. Companies use W-2 forms to verify an applicant’s employment history or to gain deeper insight into a candidate’s financial responsibility and stability, especially for management positions that have access to a company’s financial resources or budgets.

W-2 forms are widely trusted because they’re standardized, IRS-regulated, and directly issued by employers—making them one of the most reliable documents for verifying income and employment history.

How do fraudsters create fake W-2 forms?

Fraudsters tend to commit W-2 fraud using these techniques: 

• Modifying Genuine W-2 Forms: Perpetrators alter real W-2 forms to fit their needs. For income verification, they may inflate wages and tips to reflect a higher salary and corresponding Social Security taxes or tips. Those attempting to bypass employment verification often change the Employer Identification Number (EIN), employer name, address, and employment tenure.

• Creating Custom W-2 Forms: Fraudsters can generate entirely fake W-2 forms using online tools. They fill in false information about employers, income, and other details like the EIN, wages, and employer name.

• Using Stolen W-2 Data: Organized crime rings buy genuine W-2 data from online cybercriminal marketplaces. They use this real data to bypass business or mortgage loan underwriting processes to obtain funds illicitly.

4 Signs of a forged or fake W-2 form

To detect a fake W-2 form scam, it requires attention to detail. The common red flags include:

1. Incorrect information

All W-2 forms should be cross-referenced with other supporting documentation, and due diligence must be conducted. Here are some discrepancies that may indicate fake W-2 forms:

• Grammatical or Spelling Errors: Mistakes in specific fields may indicate W-2 fraud: employer’s name, address, or ZIP code.

• Debt Section: W-2 forms only report taxes withheld. If debt is present in the document, there is a high chance that it is a fake W-2.

• Incorrect EIN Format: Employer Identification Numbers (EINs) should follow the standard 9-digit XX-XXXXXXX format. Any deviations warrant further investigation.

• Invalid SSN: Fake W-2 forms may contain invalid Social Security numbers. A major red flag is if the SSN doesn’t follow the correct AAA-GG-SSSS format.

• Mismatched Data: Inconsistent personal details, such as the legal name, address, or employer name, when cross-referenced with other documents like bank statements, pay stubs, or identification. Discrepancies between the income deposit date on bank statements and the employment tenure on the W-2 form can also suggest fraud.

2. W-2 form inconsistencies

A telltale sign of fake W-2 forms is poor formatting. Genuine W-2 forms follow a standardized format, while forgeries often display issues such as:

• Font Variations: Different fonts or sizes within the same document.

• Alignment Issues: Misaligned text, uneven spacing, or inconsistent margins and columns.

• Pixelated Fonts: Blurry or distorted fonts due to alterations.

• W-2 forms not in PDF format: W-2 forms that are not in PDF format need to be inspected carefully because they are usually not an original document. Bad actors have the tendency to photograph, scan, or take screenshots of forged or fake documents to hide modifications.

3. Bad math and uncharacteristic figures 

A W-2 form should have a clear breakdown of taxes, deductions, etc, that correspond with the wages. Pay close attention to these warning signs: 

• W-2 vs Pay stub: If a W-2 form shows a higher wage than a pay stub, it indicates fraud. W-2s report taxable wages after pre-tax deductions, while pay stubs reflect gross earnings.

• Round numbers: Rounded numbers can indicate fake W-2 forms because they portray unrealistic precision which deviates from the variances found after deductions, tax withholdings, and benefits.

• Incorrect taxes: Taxes that do not align with the salary, such as identical tax amounts for different salaries across several documents, can indicate fraud.

• Excessive wages: Salaries that are highly disproportionate to the industry’s average of similarly experienced workers can indicate fake W-2 forms.

4. Wrong W-2 copy

W-2 forms come in three copies: 

• Copy A: This red W-2 form is for informational purposes only and should not be used for verification processes or filed for taxes.

• Copy B: This black W-2 form is filed for tax purposes to meet the requirements of the state, city, or local tax department.

• Copy C: This copy is for the employee and is used to verify income or employment when requested. Employees are recommended to keep each W-2 form for at least 3 years after they are filed.

Any W-2 form provided other than Copy C is likely a fake.

How to verify W-2 forms?

Verifying W-2 forms to confirm an individual’s employment and income, (especially in processes like loan approvals, tenant screening, and fraud prevention) can be done either manually or via AI.

While manual checks—such as reviewing formatting, totals, and employer details—can catch obvious red flags, they often miss subtle manipulations or forged entries that bad actors can easily generate with editing software.

That’s why we recommend using an AI-powered document verification solution for verifying W-2 forms to detect tampering, cross-reference data points, and flag anomalies at scale.

Automated verification offers speed, consistency, and resistance to sophisticated fraud tactics—far beyond what manual review alone can provide.

Manual verification

To prevent fake W-2 forms from infiltrating verification processes, start by cross-referencing data with relevant documents and federal sites.

• Verify EIN. Checking EIN prefixes and EIN numbers online to verify the listed employers on the W-2 form. If details provided are unclear, contact the IRS Business & Specialty Tax Line at 1-800-829-4933.

• Verify SSN online. Verify an applicant’s social security number by checking it online. Here are 3 additional tools:

  • • For income verification, use the Consent Based Social Security Number Verification (CBSV) Service to analyze a large number of SSNs with instantaneous results for a fee.

    • For employment screening, use the Social Security Number Verification Service to verify the names and SSNs of said employees. 

    • Free services such as SSN-Check allows a quick check of issued SSNs but this tool does not validate the SSNs of employees and non-employees.

• Check tax withholding rates. Cross-reference listed taxes with IRS data to ensure accuracy. 
  

• Check with employers. Call the employers listed on the W-2 to verify the applicant’s income, address, and legal name to confirm the authenticity, rule out W-2 form fraud, and verify the applicant’s employment history.
  
  

• Cross-reference all documents. Ensure consistency in all details such as legal name, address, wages, and other information across tax returns, pay stubs, bank statements, and other documents.

Keep in mind: Using these resources to verify income is not sustainable in the long run—especially for companies that need to process large volumes of W-2 forms.

With the prevalence of large-scale template farms and online editing tools, creating fake W-2 documents has become easier, making it tough for underwriters, employers and property managers to detect fake W-2 forms.

This makes manual inspections less effective and far more time-consuming as the naked eye struggles to spot subtle changes in metadata, formatting, and fonts. 

Using AI and machine learning software to spot fake W-2 forms 

Automated or AI-driven document fraud detection services can help underwriters and tenant screeners assess the authenticity of W2s with more speed and accuracy, giving them greater confidence in their decision-making, and allowing them to process a much greater volume of documents.

Combined with an intelligent document processing system, AI has the potential to radically transform your processes in a safe way.

• Deploy a fake W-2 form detector app: Before processing a document, you should understand if you can trust it, so fraud detection is the first step. One way is to deploy a dedicated AI document fraud detector to spot fake or forged W-2 forms.

• Use an Intelligent Document Processing (IDP) solution: Since W-2 forms follow a structured format, IDP solutions can efficiently extract, process, and cross-reference information with external sources like credit bureaus or financial institutions. The key is to automate document processing with fraud detection solutions that help mitigate risks and prevent fake W-2 forms from slipping through the cracks.

Together, these technologies not only reduce risk and manual workload, but also establish a foundation of trust and scalability in your verification workflows.
