Tax season fraud: What financial institutions and consumers should know

Tax season fraud

Tax season always brings opportunity. Unfortunately, it also brings urgency, emotion, and a spike in tax season fraud.

A recent case shows just how devastating these scams can be. A 78-year-old Michigan retiree lost nearly $1 million after fraudsters posing as IRS agents convinced him he was part of a criminal investigation. The callers told him his Social Security number had been tied to drug trafficking and money laundering and that his assets could be seized. Over time, they persuaded him to liquidate investments and move funds into accounts they controlled, all under the pretense of “protecting” his money.

This was not a single impulsive transaction. It was a sustained social engineering effort built on fear, authority, and isolation. It is also a reminder that tax season fraud is not only a consumer awareness issue. It is a financial crime risk event that directly affects financial institutions.

The scale and sophistication of tax season fraud

The IRS reports billions of dollars lost each year to tax-related scams and identity theft. Impersonation schemes remain one of the most common tactics. As in the Michigan case, criminals often claim to represent the IRS and threaten arrest, license suspension, or asset seizure if immediate payment is not made.

Tax season fraud works because it taps into predictable human reactions:

  • Fear of legal consequences
  • Trust in government authority
  • Urgency that pushes people to act before they think

Fraudsters understand this psychology, and financial institutions need to understand it as well.

Who fraudsters target during tax season

Tax season fraud does not discriminate. However, certain groups are targeted more frequently because of financial position, life stage, or perceived vulnerability.

Older adults

Older adults remain a primary target, particularly in impersonation scams. Many retirees have accumulated savings across deposit, brokerage, and retirement accounts. That makes them attractive to criminals looking for larger balances.

Equally important, some older individuals may be more inclined to trust a caller who claims to represent the IRS, the Treasury Department, or law enforcement. Fraudsters use official language, badge numbers, and fabricated case IDs to reinforce credibility. They often spoof phone numbers to make the call appear legitimate.

For banks and credit unions, behavior can be as important as dollar amount. Warning signs may include:

  • Sudden liquidation of investment or retirement accounts
  • Large wire transfers after repeated phone calls
  • Customers expressing fear of arrest or asset seizure
  • Reluctance to discuss the purpose of a withdrawal

Frontline staff trained to recognize elder financial exploitation and fraud tactics in general can stop tax season fraud before funds leave the institution.

First-time filers and young adults

Young adults and first-time filers often lack experience with IRS processes. They may assume that email, text, or phone outreach is regular. Fraudsters rely on that uncertainty.

Many scams aimed at this group focus on refunds. Messages that claim a refund is delayed or requires verification can feel believable. When someone is expecting money, urgency does not seem suspicious.

Younger consumers may also be more likely to click links sent via text or social media. That increases exposure to credential harvesting and identity theft tied to tax season fraud.

From an institutional perspective, this activity can look different:

  • Multiple failed login attempts followed by password resets
  • New accounts opened to receive direct deposit refunds
  • Rapid outbound transfers after a refund posts

Connecting these signals across channels is essential.

Immigrants and non-native English speakers

Fraudsters frequently tailor tax season fraud narratives to immigrants and non-native English speakers. Threats may include deportation, visa revocation, or immediate legal action.

These scams are heavily intimidation-based. Victims may be hesitant to question someone claiming to be a government official. Language barriers can make it harder to verify information or seek help.

Financial institutions serving diverse communities should consider:

  • Offering fraud education materials in multiple languages
  • Training staff to recognize fear-based narratives tied to immigration status
  • Establishing clear escalation procedures when a customer appears distressed

Across all groups, transaction context matters. Significant or unusual withdrawals tied to urgent stories about government investigations should raise red flags. Empowering employees to pause a transaction and escalate concerns can significantly reduce losses.

Common tax season fraud tactics

While tactics evolve, several schemes appear year after year during filing season.

IRS impersonation scams

IRS impersonation remains one of the most damaging forms of tax season fraud. Criminals claim to be IRS agents and demand immediate payment for alleged back taxes, penalties, or criminal investigations.

Common elements include:

  • Threats of arrest, license suspension, or asset seizure
  • Demands for payment via wire transfer, cryptocurrency, or gift cards
  • Instructions to move funds into so-called secure accounts
  • Pressure to stay on the phone while completing transactions

The IRS generally initiates contact by mail. It does not demand immediate payment over the phone or request gift cards or cryptocurrency.

Financial institutions should watch for customers who appear coached, reference badge numbers or case IDs, or express fear of immediate legal consequences. Those behavioral cues often accompany tax season fraud.

Phishing emails and text messages

Phishing campaigns increase sharply during filing season. Messages commonly claim:

  • “Your refund is ready.”
  • “Unusual activity detected.”
  • “Verify your tax information.”

Victims are directed to websites that closely resemble IRS pages. Once credentials and Social Security numbers are entered, criminals can file fraudulent returns, redirect refunds, or attempt to take over accounts.

Downstream effects may include:

  • Changes to direct deposit instructions
  • New external account linkages
  • Suspicious ACH activity after credential resets

Layered authentication and anomaly detection help reduce exposure to tax season fraud initiated through phishing.

Refund theft and identity fraud

In refund theft schemes, criminals file fraudulent tax returns using stolen Social Security numbers before the legitimate taxpayer files. Victims often discover the problem only when their return is rejected.

Filing early may reduce the risk, but identity theft frequently begins months earlier through unrelated data breaches or phishing incidents. Continuous monitoring remains critical.

Institutions should pay attention to:

  • Newly opened accounts receiving tax refunds
  • Immediate withdrawal of refund funds
  • Rapid transfers to external accounts

These patterns can signal mule activity connected to tax season fraud.

Fraudulent tax preparers and online “tax hacks.”

Some tax season fraud originates with individuals posing as legitimate tax preparers. Red flags include:

  • Promises of substantial refunds
  • Fees based on a percentage of the refund
  • Refusal to sign the return as the preparer

Social media has also amplified fabricated refund strategies. Advice that encourages falsifying income or inventing credits not only creates fraud exposure but also serious compliance risk for the taxpayer.

These schemes can result in financial loss, penalties, audits, and long-term identity misuse.

Financial institutions can reinforce consumer protection by encouraging customers to verify preparer credentials such as CPA, EA, or attorney designations, sharing IRS guidance on legitimate filing procedures, and monitoring for unusual refund activity.

How consumers can reduce exposure to tax season fraud

Preventing tax season fraud requires steady, practical vigilance. Consumers should protect personal information year-round, shred tax documents before discarding them, and store prior-year returns securely in both physical and digital formats.

Strengthening digital security is also essential in combating fraud and identity theft. Use strong, unique passwords for financial and tax accounts and enable multi-factor authentication. Avoid filing taxes on public Wi-Fi.

Instead of reacting immediately to unexpected tax communication, slow down and verify:

  • Go directly to IRS.gov rather than clicking links
  • Contact your tax preparer using a trusted phone number
  • Independently confirm any request for payment or account changes

Monitor accounts regularly. Review bank, brokerage, and credit card statements. Early detection can significantly limit loss.

The role of financial institutions in preventing tax season fraud

Tax season fraud affects both fraud and anti-money laundering (AML) teams and frontline staff. Institutions should expect increased alert volume and unusual transaction activity during filing season. Practical steps include:

  • Monitoring for large or atypical withdrawals tied to government investigation narratives
  • Identifying rapid liquidation of investment accounts combined with outbound wires
  • Training frontline employees to recognize fear-based behavioral cues
  • Establishing clear escalation paths when elder financial exploitation is suspected

Cross-channel visibility is critical. Fraudsters often coach victims on precisely what to say. Employees who feel supported in pausing transactions and escalating concerns can prevent significant losses.

Proactive customer education also matters. Clear communication about tax season fraud reinforces trust and demonstrates a commitment to protecting the community.

Preparedness, not panic

Tax season will continue to attract criminal activity. The pressure of tax obligations and the anticipation of refunds create an environment where social engineering can thrive. Awareness, sound controls, behavioral monitoring, and consistent education materially reduce exposure to tax season fraud.

For consumers, skepticism and verification are robust safeguards. For financial institutions, vigilance and timely intervention make a measurable difference. Preparedness, not panic, remains the most effective defense.
