Tax Evasion Red Flags: What Small Businesses Should Look For When Hiring Contractors

Stop Tax Evasion from Hitting Your Bottom Line: Practical Steps for Vetting Contractors After the Rhode Island Adjuster Conviction

Hook: If you hire independent contractors, one legal misstep by a vendor can create audit exposure, unexpected payroll liabilities, and reputational damage. The January 2026 conviction of a Rhode Island public adjuster for repeated federal tax crimes — including a 2025 guilty plea that produced more than $1.36 million in restitution — is a wake-up call for small businesses to tighten contractor vetting, reporting, and contracting practices.

Why this matters now (2026 trends)

Federal prosecutions and large restitution orders for tax evasion continued to rise in late 2025 and early 2026. The U.S. Department of Justice and IRS Criminal Investigation have prioritized complex schemes involving cash-based services, underreported receipts, and repeat offenders operating multiple business entities. At the same time, IRS data-matching and electronic information-sharing improvements mean noncompliance is being detected faster than before. For small businesses that rely on 1099 contractors, the practical implication is clear: you must document due diligence and adopt contract language that limits exposure.

What happened in Rhode Island — key lessons

In August 2025 William N. L’Europa pleaded guilty to federal tax evasion; in January 2026 he was sentenced to probation and ordered to pay $1,367,336.08 in restitution for unpaid taxes, penalties, fees and interest for tax years 2007–2013. Court records show this was not an isolated episode — L’Europa had prior federal convictions for filing false tax returns and conspiracy to defraud the United States (2012 conviction and a 27-month sentence).

"A Rhode Island man who ran public adjuster and property restoration businesses and who was previously twice convicted for federal tax charges was sentenced this week in U.S. District Court for tax evasion." — Insurance Journal, Jan 16, 2026

Takeaway: repeat offenders and business owners who operate multiple related entities present the highest risk. If your vendor has a history of tax litigation, you need stronger controls — not a handshake.

Red flags that should trigger immediate escalation

When vetting contractors, look for these specific red flags. Any one of them should trigger enhanced due diligence, and multiple together should change your onboarding decision.

• Refusal to provide a completed Form W-9 or evasive responses about TIN/EIN.
• Requests to be paid "off-books" (cash-only payments, split invoicing, or requests for payments to third parties).
• History of tax liens, judgments, or public court records alleging fraud or tax offenses.
• Multiple business names or shell entities used interchangeably without clear business purpose.
• Significant discrepancies between invoice volumes and public financial disclosures or prior tax records if available.
• Prior criminal convictions for fraud, theft, or tax crimes; repeated short-term jail sentences or probation for related offenses.
• Unwillingness to certify compliance with tax and reporting obligations, or no proof of registration with state tax authorities where required.
• Indications of payroll/independent-contractor misclassification risk — control over hours, equipment, and exclusivity that resembles employment.

Due diligence checklist for hiring contractors

Below is a step-by-step checklist you can use before signing contracts and issuing the first payment.

1. Obtain and verify a completed Form W-9

   Require a signed Form W-9 for every contractor. Use the IRS TIN Matching program (available through IRS e-Services) to confirm the legal name/TIN match before filing 1099s. If you cannot confirm the TIN/name, consider backup withholding or delaying onboarding. See identity controls guidance for practical verification checkpoints.

2. Run corporate and business registration checks

   Confirm the contractor’s business is registered with the state (Secretary of State) and is in good standing. For sole proprietors, confirm if they maintain a DBA and whether the EIN/SSN provided matches public records.

3. Perform background checks within legal limits

   Obtain written consent and conduct criminal history checks consistent with the Fair Credit Reporting Act (FCRA) and state law. Focus on convictions for tax crimes, fraud, theft, and money laundering. Document the consent and the scope of the check.

4. Request proof of tax compliance

   Ask for recent evidence of tax compliance such as prior-year tax returns (redacted where appropriate), proof of payroll tax filings if they employ others, or a letter from their CPA. If they refuse, require stronger contractual protections. For payment-related red flags (off-books requests or unusual settlement terms), consider how instant settlement practices change risk profiles for small vendors.

5. Confirm insurance and bonding

   Request certificates of insurance (COI) and performance bonds where appropriate. Include the business as an additional insured when exposure warrants it. Short-term, cash-heavy operations (food stalls, event vendors) often document COIs — see short-term food stall guidance for industry examples.

6. Collect references and verify project invoices

   Call references and verify that invoice amounts and payment terms align with industry norms. Look for inconsistent billing patterns or unexplained discounts that might conceal unreported income.

7. Document classification analysis

   Maintain a written independent-contractor classification analysis using the IRS common law factors and any relevant state tests. If the facts are borderline, classify conservatively or consider hiring as an employee. Automating parts of onboarding and document collection can reduce friction — explore partner-onboarding automation to scale safe practices.

8. Lock in contract representations and audit rights

   Include clauses (samples below) requiring contractor tax compliance, cooperation in audits, and indemnity for tax liabilities.

Reporting obligations and immediate actions if you suspect tax crimes

Small businesses have limited affirmative obligations to report contractor tax crimes, but there are critical compliance steps and protective measures to take immediately.

Maintain accurate information reporting

File Form 1099-NEC for nonemployee compensation of $600 or more by the IRS deadline (typically Jan 31 for both furnishing to payee and filing with the IRS). Keep copies and receipts for at least 4 years. If you discover incorrect information, file corrected 1099s promptly.

Backup withholding obligations

If a payee fails to provide a correct TIN or the TIN/name mismatch is not resolved, you may be required to begin backup withholding at the current statutory rate (24% in recent years). Document attempts to obtain correct information and follow IRS procedures to stop withholding once corrected.

When to notify the IRS or law enforcement

There is no automatic duty for ordinary businesses to report a contractor’s suspected tax crime, but consider notifying IRS Criminal Investigation (CI) or your legal counsel when:

• You find clear evidence of intentional tax evasion by a contractor that affected payments you processed.
• Your own records show systematic misreporting that might indicate collusion or facilitation.
• You are contacted for assistance by law enforcement, or you receive a subpoena or grand jury request.

Carefully document internal steps: date you discovered the issue, who you informed, actions taken, and copies of correspondence. This record is critical to show you exercised due diligence if regulators later examine your files.

Contract clauses that reduce exposure — practical language

Below are practical, enforceable clause examples you can adapt. Always have local counsel review for enforceability in your state and industry.

1. Tax Compliance Representation

Sample: "Contractor represents and warrants that it is properly classified as an independent contractor under federal and state law, that it maintains all applicable tax registrations, and that it has filed and paid all federal, state and local taxes due as of the Effective Date. Contractor will provide proof of tax filings and registrations upon Company’s reasonable request."

2. Indemnity for Tax Liabilities

Sample: "Contractor shall defend, indemnify and hold Company harmless from any and all claims, liabilities, taxes, interest, penalties, and expenses (including reasonable attorneys' fees) arising from Contractor’s failure to report income, pay taxes, or comply with applicable tax laws. This indemnity survives termination of this Agreement for a period of five (5) years."

3. Audit and Cooperation Clause

Sample: "Contractor agrees to cooperate fully with Company and any governmental audit related to services provided under this Agreement, including producing tax documents, payroll records, invoices and bank statements within fifteen (15) business days of written request. Costs of producing records shall be borne by the Contractor unless Company is found at fault."

4. Right to Withhold and Escrow

Sample: "If Contractor fails to provide a valid Form W-9 or if Contractor’s compliance is reasonably suspected, Company may withhold twenty-four percent (24%) of payments, deposit funds into an escrow account, or suspend payments until resolution. Withheld funds may be applied to any tax obligations finally assessed against Contractor that relate to services under this Agreement."

5. Termination for Criminal Conviction

Sample: "Company may terminate this Agreement for cause upon written notice if Contractor is convicted of a felony, any crime involving fraud or dishonesty, or a tax-related offense. Termination is effective immediately upon written notice and Contractor shall forfeit outstanding fees where Contractor’s conduct resulted in liability to Company."

How to respond if a contractor is convicted (or suspected) of tax evasion

Follow these immediate steps to protect your business:

• Freeze payments: If permitted by contract, suspend nondisputed payments and open a dialogue with counsel.
• Document everything: Preserve invoices, emails, W-9s, COIs, and payment records. Implement a litigation hold if necessary.
• Assess your risk: Determine whether your business facilitated or had knowledge of the contractor’s misconduct. If you have reason to believe you may be implicated, retain defense counsel immediately.
• Correct information returns: File corrected 1099s and other amended returns if your filings were erroneous.
• Notify insurance carriers: Claims-made policies or fidelity bonds may cover certain losses; consult counsel before making admissions.
• Cooperate with authorities: When contacted by IRS CI or other investigators, cooperate but involve counsel to manage privilege and exposure. If you need to reconstruct transaction histories quickly, forensic teams often use scalable analytics stacks; see guidance on large-scale data reconstruction for examples.

Advanced strategies for high-risk categories (construction, restoration, adjusters)

If you operate in industries with frequent cash transactions or subcontracting (construction, restoration, public adjusting), adopt these additional controls:

• Use tiered onboarding: Higher-risk contractors require more documentation (CPA letters, multi-year W-9s, proof of payroll for hired workers).
• Require direct deposit to business account: Avoid payments to personal accounts or third parties; consider modern settlement options described in freelancer settlement guides when evaluating payment flows.
• Implement invoice review controls: Require dual approval for invoices above a threshold and periodic reconciliation against work orders.
• Reserve retention: Hold a percentage (retention) until project completion and final tax compliance is certified.
• Annual compliance attestations: Have contractors annually certify they are current on taxes and will provide supporting documentation on request.

When to involve counsel and forensic accountants

Engage external counsel in any of these situations:

• Evidence of systematic underreporting or falsified invoices.
• Requests for payment structures that could facilitate tax evasion.
• Subpoenas, grand jury inquiries, or contact from IRS CI.
• Potential payroll tax exposure from misclassification.

Forensic accountants can reconstruct flows and identify whether underreporting by a contractor affected your 1099 reporting or created conduit payments that might implicate your business; scalable analytics patterns for investigation are described in ClickHouse for scraped data references.

Recordkeeping and retention: how long and what to keep

Maintain contractor records for at least four to seven years depending on state law and the type of documentation. Key records include:

• Signed contracts and W-9s
• Invoices, receipts, and proofs of payment
• Insurance certificates and bonds
• Background check consent and reports
• 1099-NEC forms and proof of filing
• Communications about classification and tax compliance

Operationally, treat retention as a data ops problem — scheduling, observability, and privacy workflows are important; see Calendar Data Ops for patterns you can adapt to compliance schedules.

Final checklist — quick actions you can implement today

• Require Form W-9 before the first payment.
• Use IRS TIN Matching for payees (register for e-Services).
• Insert tax compliance, indemnity, audit cooperation, and termination for conviction clauses in all new contractor agreements.
• Set up a policy for backup withholding triggers and who signs off.
• Run a baseline criminal and civil judgment check on contractors in high-risk roles.
• Document classification analyses and maintain conservative positions where facts are ambiguous.
• Train procurement and accounts payable teams to spot red flags (cash requests, third-party payment requests).

Summary — practical risk reduction in 2026

The Rhode Island adjuster case is a real-world example of how vendor misconduct can surface years after the underlying transactions. In 2026, with enhanced IRS analytics and criminal enforcement, small businesses cannot rely on informal vetting. Instead, implement documented checks (W-9s, TIN Matching), adopt enforceable contract protections (indemnities, audit cooperation, withholding rights), and escalate suspicious signs to counsel and, when appropriate, to IRS Criminal Investigation.
