What Is an Outside Business Activity Under FINRA?

An outside business activity under FINRA is any work a registered securities professional does away from their broker-dealer that involves either a formal role or compensation, and FINRA Rule 3270 requires you to give your firm prior written notice before you start.¹ The role can be as an employee, independent contractor, sole proprietor, officer, director, or partner of another entity. The compensation can be money you already receive or money you reasonably expect to receive. If either applies, the notice requirement is triggered, and the activity does not have to relate to the securities industry to count.

What Triggers the Rule

Rule 3270 reaches almost any business relationship outside your firm. Two things trigger it: holding a formal position at another entity, or receiving (or reasonably expecting) compensation from an outside source.¹ The outside work does not need any connection to securities. Landscaping, weekend tutoring, running a restaurant, and freelance consulting all qualify.

The compensation piece is broader than a paycheck. If you hold a role where payment is reasonably likely later, that counts. Helping a friend launch a startup with the understanding that you’ll eventually get equity or a share of revenue fits the definition. So does any paid consulting or freelance work.

Family businesses land in the same category. If you serve as a partner, officer, or director at a family-owned company, the rule applies regardless of the family connection. Even unpaid help can trigger reporting if there’s a title attached or a reasonable expectation of future pay.

Common Reportable Activities

The range of outside activities FINRA expects you to disclose is wider than most representatives assume when they first register. Common examples:

Part-time employment: retail work, teaching a class, or coaching a team for pay.
Board positions: serving as a director for a for-profit company or a nonprofit. Section 13 of Form U4 lets you exclude non-investment-related activity that is exclusively charitable, civic, religious, or fraternal. Anything beyond that scope needs disclosure.
Consulting and freelancing: paid expertise in any field, whether marketing, accounting, technology, or real estate.
Owning or operating a business: running a sole proprietorship, actively managing rental property as a business, or co-owning an LLC.
Monetized digital content: ad revenue, sponsorships, or affiliate income from a YouTube channel, podcast, blog, or social media account.

Firms evaluate each disclosure to see whether the activity might interfere with your primary duties, confuse clients about what the firm offers, or create a conflict of interest. Something that looks harmless can still raise flags if it touches the firm’s customers or competes with the firm’s business lines.

What You Don’t Have to Report

Rule 3270 explicitly exempts passive investments.¹ Owning stocks, bonds, mutual funds, or other securities in a personal account is not an outside business activity. Holding a rental property where you collect rent without actively managing it as a business generally falls into the same passive category. The distinction turns on whether you are actively working in a business capacity or simply holding an investment.

Activities covered by FINRA Rule 3280, which governs private securities transactions, are also carved out of Rule 3270. Rule 3280 has its own notice and supervision framework, and it applies when your outside activity involves participating in a securities transaction rather than running a non-securities business.² Selling interests in a real estate syndicate, raising capital for a startup, or brokering a private placement are examples that land in Rule 3280 territory.

If the firm approves a private securities transaction where you receive or may receive selling compensation, the firm has to record and supervise the transaction as if it were executed on the firm’s own behalf.³ That’s a heavier standard than what applies to a typical outside activity. If your outside work involves securities in any way, disclose it and let compliance decide whether Rule 3270 or Rule 3280 governs. Getting the classification wrong can put you in violation of both.

How to File the Disclosure

Disclosures go through Section 13 of Form U4, titled “Other Business.” Section 13 asks whether you are currently engaged in or planning to engage in any other business as a proprietor, partner, officer, director, employee, trustee, or agent.⁴ You provide:

The legal name of the entity, its address, and a description of what the business does.
Your title or position and the start date of your involvement.
Whether the activity is investment-related.
An estimate of hours per month you spend on it.

You submit through your firm’s compliance department, which files electronically with the Central Registration Depository.⁵ The timing rule is strict: notice has to be given before you begin the outside activity.¹ Starting the work first and filing after is itself a violation, whether or not the activity would have been approved.

You cannot proceed until the firm approves. Compliance has full authority to restrict or prohibit any activity it considers risky. Once an activity is on file, you have a continuing obligation to update it if anything material changes. Form U4 amendments are generally due within 30 days.⁶ Disclosed activities also appear on your BrokerCheck profile, visible to clients and the public.⁵

What Happens If You Don’t Disclose

Failing to disclose is one of the more common FINRA violations, and the penalties are real. Firms are expected to impose significant consequences for non-disclosure, including heightened supervision, internal fines, and termination.³ On the regulatory side, FINRA disciplinary actions for these violations can bring monetary fines, suspensions, or in serious cases, a permanent bar from the industry.

The failure to disclose is the violation, even when the underlying activity is completely benign. Representatives have been sanctioned not because a side business harmed anyone, but because the firm was never told. The violation lands on your CRD record, shows up on BrokerCheck, and follows you for the rest of your career.

A Proposed Consolidated Rule

FINRA has proposed replacing Rules 3270 and 3280 with a single consolidated rule, described in Regulatory Notice 25-05.⁷ The proposal would narrow the primary disclosure requirements to investment-related activities, defined as those involving securities, crypto assets, commodities, derivatives, currency, banking, real estate, or insurance. Representatives with purely non-investment side businesses would face lighter obligations, and activities performed on behalf of a firm’s affiliate would be excluded because they’re already supervised internally.

The current rules stay fully in effect until the SEC approves the change.³ Every outside activity, investment-related or not, still requires prior written notice today. File under the existing framework and watch for whether the consolidated rule takes effect during the life of that activity.
