William Bernard Tunink, a former registered representative who held registrations at LPL Financial LLC and Avantax Investment Services Inc., was suspended by the Financial Industry Regulatory Authority in June 2026. The suspension follows alleged failures to provide information requested by FINRA under Rule 8210.
What happened
FINRA disciplinary records show that Tunink did not respond to regulatory requests for information. Under FINRA Rule 8210, all registered individuals must cooperate with regulatory inquiries and keep their records current.
The suspension prevents Tunink from associating with any FINRA-member brokerage firm until the matter is resolved or the suspension period expires. He remains bound by securities arbitration agreements with former customers.

Broker details
Tunink career included stints at two prominent firms. LPL Financial is the largest independent broker-dealer in the United States, serving thousands of financial advisors. Avantax Investment Services is the brokerage subsidiary of Avantax, a tax-focused wealth management firm.
Both firms are responsible for supervising their registered representatives and ensuring compliance with FINRA information-sharing requirements. When a registered person fails to respond to FINRA, the employing firm may face reputational and supervisory scrutiny.
What investors should know
Clients who worked with Tunink at either LPL Financial or Avantax should review their account documentation. While this suspension is for non-cooperation rather than a specific investment violation, any history of regulatory issues may be relevant to assessing the quality of advice received.
Investors can access Tunink full BrokerCheck record through FINRA public database. This includes employment dates, disclosure history, and any customer complaints.
What affected investors can do now
Investors who had Tunink as their registered representative should consider these steps:
- Request a complete copy of account records from the period of the relationship
- Run a BrokerCheck search for any additional disclosures
- Compare recommended investments against personal risk tolerance
- Seek legal counsel if account losses appear unusual
Common mistakes victims make
Investors frequently overlook broker suspensions that do not involve direct financial misconduct. A Rule 8210 violation, while administrative, can signal deeper compliance failures at the firm level.
Some clients discard old account statements, believing they are no longer needed. Those documents are essential for tracing unauthorized trades, unsuitable recommendations, and fee overcharges.
Another error is accepting a firms internal review as the final word. Broker-dealers have an incentive to minimize liability. Independent legal counsel offers a more objective assessment of whether losses were avoidable.
Regulatory context
FINRA Rule 8210 violations have become a significant enforcement category. The regulator has made clear that cooperation is not optional. Firms and individuals who ignore information requests face swift suspension.
The June 2026 actions against multiple brokers highlight FINRA commitment to maintaining accurate and accessible records. Investors benefit from this transparency because it ensures that disciplinary information is captured and available.
The FINRA arbitration process offers a streamlined alternative to court litigation. Most brokerage agreements include mandatory arbitration clauses, which means disputes are heard by a panel of arbitrators rather than a judge. The process typically resolves within 12 to 18 months, compared to years for civil court cases.
Investors who believe they suffered losses due to Tunink recommendations should request a free consultation with a securities attorney. Many firms offer case evaluations on a contingency basis, meaning no upfront legal fees and payment only if recovery is achieved.
