FINRA Rule 3270 prohibits registered securities professionals from engaging in any business activity outside their primary firm unless they provide prior written notice to their employer. You might consult on the side, sit on a company board, or run a small business after hours. The rule was made so your firm can catch any conflict of interest before it hurts a client. Get the disclosure wrong, and you put your registration and your reputation on the line.
This guide walks through what the rule requires, what actually counts as an outside business activity, and how a major proposed change could reshape the entire framework in 2026.
If you are concerned that your securities professional might have violated certain disclosure rules, a knowledgeable FINRA arbitration lawyer can help you understand your options.
What is FINRA Rule 3270?
FINRA Rule 3270 prohibits broker-dealers and registered representatives from engaging in any outside business activities that involve the sale of securities unless they have first provided written notice to their employing firm. “Outside business activity” refers to a registered person’s (not associated persons) involvement in offering, purchasing, or selling securities outside of their broker-dealer’s regular business activities.

The rule a registered person’s responsibilities so firms can spot conflicts of interest before they harm clients or the firm itself.
Under FINRA Rule 3270, you cannot start the outside activity first and explain it later, because the firm needs the chance to assess the activity in advance.
Once your firm receives notice, it has to decide whether the activity interferes with your duties to clients, or whether the public might reasonably see it as part of the firm’s business. The firm can approve the activity, place conditions on it, or prohibit it outright.
What Counts as an Outside Business Activity?
An outside business activity is any business conducted outside the scope of your relationship with your firm, whether or not it involves securities. The definition is broad on purpose, which is why so many representatives are surprised by what falls under it.
Being an employee, independent contractor, sole proprietor, officer, director, or partner of another business can all trigger the rule, since such activities span many business lines. So can accepting compensation, or having the reasonable expectation of compensation, from a person other than your firm. The activity does not have to be investment-related to require notice under the current rule.
FINRA outside securities transactions are broadly defined. FINRA Rule 3270 states that they include any paid work performed outside of a securities professional’s employment. This includes outside business ventures and:
- Working as an employee for another company;
- Working as an independent contractor for another company;
- Serving as an officer, director, or partner of any outside board or organization;
- Receiving payment for any outside services, including payment in digital assets or digital asset activities; and
- Having the reasonable expectation of being paid for any outside business activities.
This rule only requires an investment advisor to notify his or her employer of FINRA outside business activities.
The reporting obligation is on you. However, it does not require the investment advisor to do anything beyond provide a notification. Instead, the FINRA member firm makes a determination about what outside business activities are acceptable to the firm and its clients.
The firm decides how or if outside business activities should continue to be carried out.
Common Examples of FINRA Outside Business Activities
Common examples of outside business activities include:
- Acting as both a financial advisor and a certified public accountant;
- Sitting on the board of directors of an outside organization, whether or not this activity is paid work; and
- Advising a start-up company for free but expecting future compensation once the company begins to turn a profit.
Your investment advisor needs to report any of these activities in their OBA disclosure to their employer under FINRA 3270.
The examples above are not exhaustive. An investment adviser also needs to report their wedding photography business or snorkel tour side-gig to their employer under the rules. FINRA rules about outside business activities apply to any paid work.
What Is Not an Outside Business Activity
Passive personal investments generally don’t count as outside business activities, since you’re not actively running a business. FINRA Rule 3270 exempts passive investments outright, like buying stock for your own account or holding a rental property in your own name, though firms vary in how they treat real estate.
Activities that already fall within your role at the firm are excluded too, since those sit inside the scope of your relationship with the firm. The line just becomes unclear when a side activity starts to overlap with your firm duties. Clarify that kind of situation with your compliance department before you move forward.
While FINRA Rule 3270 casts a wide net, it allows investment advisers to make passive personal investments. Investing in diversified index funds or private securities transactions is not an outside business activity.
Investment advisers may also put their personal funds into a blind trust. Blind trusts do not allow people to direct how their money is invested.
Other FINRA rules require some disclosure about personal investments to ensure that your broker is being as transparent as possible about their potential conflicts of interest.
FINRA Rule 3280 requires disclosure of private securities transactions. Your securities professional must strictly comply with this rule and its requirements. Your brokerage firm should ensure the investment adviser’s compliance with FINRA Rule 3280.
Note: FINRA rules do not strictly prohibit business activities or transactions with immediate family members. However, registered representatives must still provide prior written notice to their firm for outside business activities and adhere to specific disclosure or exemption requirements for family accounts and private securities transactions.
Latest FINRA Developments on Outside Activities: What Should Investors Look For?
The latest FINRA developments on outside activities matter to investors because updated outside-activity oversight equals stronger conflict detection when a broker’s side business can influence recommendations or divert client funds. Proposed Rule 3290 equals a streamlined framework because it is designed to combine outside business activity and private securities transaction concepts into one set of notice-and-supervision expectations.
In practical terms, an outside business activity often equals a hidden incentive because compensation from an insurance agency, real estate venture, private company role, or referral arrangement can change what a client is told about risk and liquidity. At our investment fraud firm, our lawyers have seen outside ventures used to pitch promissory notes, private placements, or “friends-and-family” deals that never appear on firm statements, which is a red flag because supervision is harder when transactions occur away from the brokerage.
If you suspect harm, documentation equals leverage because the strongest cases typically include emails/texts, offering materials, proof of payments, and a timeline of who said what and when. Loss recovery often equals FINRA arbitration because a firm may be liable when it failed to review, limit, or stop an advisor’s outside activity that created investor losses.
Other FINRA rules require some disclosure about personal investments to ensure that your broker is being as transparent as possible about their potential conflicts of interest.
Responsibility of Brokerage Firms to Clients
Once an investment advisor makes an outside business activities disclosure, the FINRA member firm must take important action. Each firm typically has its own form for reporting and its own protocol for review.
How Do Firms Determine Whether an Outside Business Activity Is Acceptable?
Once a firm receives a disclosure, it needs to decide whether the outside business activities are acceptable. The FINRA member firm reviews all facts surrounding the disclosure. Then the firm answers two key questions to protect investors like you.
First, Rule 3270 asks a FINRA member firm to consider all the circumstances surrounding the outside business activities.
The review includes assessing the type of outside business, reviewing the time spent on the business, and confirming the type or amount of compensation received.
The firm must decide whether outside business activities will interfere with the securities professional’s responsibilities to their employer and/or the firm’s clients.
Second, Rule 3270 asks a FINRA member firm to think about whether outside business activities will be viewed by customers or the public as part of the member’s business.
This review assesses whether a client would confuse the investment adviser’s outside business activities with their securities business.
How Do Firms Address Outside Business Activities That Conflict with an Advisor’s Duties?
If the firm determines that the investment adviser’s outside business activities interfere with their responsibilities to the firm or its clients, then the firm should limit or prohibit the activity.
FINRA Rule 3270 also requires firms to maintain a record of compliance. It is the firm’s responsibility to keep records of all outside business activities disclosures and compliance reviews.
Brokerage firms are responsible to their clients to ensure that they are providing appropriate and conflict-free service in managing client assets.
FINRA member firms must represent that their investment advisers are not engaging in outside business activities that compromise client interests.
If you believe that your brokerage firm has failed to hold investment advisers accountable to FINRA Rule 3270 or otherwise adhere to conflict of interest rules, the firm may be liable for investor losses. Now may be the time to file a FINRA complaint against your advisor or broker.
In 2025, FINRA issued Regulatory Notice 25-05 proposing new Rule 3290. This proposed rule would consolidate the existing rules, Rule 3270 and Rule 3280 on private securities transactions, into a single framework. FINRA reviewed more than 200 comment letters before filing the revised proposal with the SEC in January 2026.
The proposed rule reorients the entire framework around investment-related activity, focusing on real risk instead of every outside venture you might pursue. Under Rule 3290, the disclosure requirement would center on activities involving financial assets, including securities, commodities, currency, and crypto assets.
Keep an eye on this proposal if you currently disclose (or should be disclosing) an outside activity, since the scope of what counts as reportable could shift once Rule 3290 takes effect, and your firm may update its compliance procedures before the rule is even final.
What Would Change Under Rule 3290
FINRA’s proposed rule change wants to cut the burden the broad current rule creates and redirect compliance attention toward activities that actually carry risk to investors. So low-risk activities the current rule technically captures, like driving for a rideshare app, coaching your kid’s soccer team, or sitting on a civic board, would generally fall outside the new rule.
The SEC published the proposal in the Federal Register on February 3, 2026, and the initial public comment period closed on February 24, 2026. FINRA then filed an amendment, and the SEC opened formal proceedings to decide whether to approve or reject the rule, which pushes the review further into 2026.
Rule 3270 stays in effect until that process wraps up, so for now, keep complying with the current rule.
Consequences of Non-Compliance
Failing to disclose an outside business activity can lead to serious regulatory and professional consequences. FINRA can bring disciplinary action. Undisclosed OBAs, along with related customer complaints, are among the more common reasons representatives face sanctions.
The fallout often follows you well past the disciplinary action itself. A finding can land on your BrokerCheck record, where current and prospective clients and employers can see it, and that visibility can stick around for years.
In some cases, an undisclosed activity also triggers a termination that gets reported on Form U5. A termination tied to compliance failures can make finding your next position far harder, which is why the disclosure step is worth taking seriously every single time.
How Undisclosed OBAs Harm Investors
When an outside activity stays hidden, investors lose the protection the rule was built to provide. The firm never gets to assess the conflict, so no one is positioned to catch a recommendation that quietly serves the representative’s outside interest.
If you are an investor who suspects your advisor was running an undisclosed side business, you may be feeling unsure about whether anything improper actually happened. It is understandable to feel that way, because these arrangements are designed to stay out of view. The harm often shows up as unsuitable recommendations, unexpected losses, or investments that never appeared on your official account statements.
Investment fraud lawyers can help investors trace these hidden conflicts and pursue recovery when an undisclosed outside activity contributed to their losses. If your advisor put a side business ahead of your interests, that overlaps with a broader failure to act in your best interest.
What Investors Can Do
Suspect an undisclosed outside activity caused your losses? Start pulling together your account records and any communications tied to the investments in question. Proper documentation helps you write a claim you can actually pursue.
You can also check your representative’s history on FINRA BrokerCheck, which shows disclosed outside activities, past complaints, and any disciplinary events.
From there, an experienced securities attorney can evaluate whether the conduct violated Rule 3270 and whether you have grounds for a FINRA arbitration claim. You won’t know exactly where you stand until someone reviews the specific facts of your case, since these claims often turn on details that are easy to miss without knowing how the rule works.
