Do You Need State Blue Sky Filings? Reg CF, Reg D and Reg A+ Preemption Explained

For most modern online raises, you do not register with individual states — but you almost certainly still owe state notice filings and fees. Reg CF, Reg D 506(b)/506(c), and Reg A+ Tier 2 offerings sell "covered securities" that are preempted from state registration under Section 18 of the Securities Act, added by the National Securities Markets Improvement Act of 1996 (NSMIA). Reg A+ Tier 1 and Rule 504 offerings get no such preemption and must clear each state individually.

This distinction is the single most misunderstood piece of capital-raising compliance we encounter. Founders hear "blue sky preemption" and conclude that states are irrelevant to their raise. They are not. Preemption removes the registration requirement — the expensive, slow, merit-review process — while leaving three things fully intact: notice filings, state fees, and state antifraud enforcement. Miss the first two and you have a technical violation on a raise that was otherwise compliant. Miss the third and you have a much larger problem.

What "blue sky" actually means

Before 1996, an issuer selling securities in the United States faced two layers of regulation: federal registration or exemption at the SEC, and separate registration in every state where a security was offered or sold. State securities laws — nicknamed "blue sky laws," after a judicial description of speculative schemes with no more basis than so many feet of blue sky — were not uniform. Some states applied merit review, meaning a state administrator could block an offering not because disclosure was inadequate but because the regulator judged the deal itself unfair to investors.

For a company raising nationally, that meant up to 50-plus separate reviews, each with its own forms, timelines, fees, and substantive standards. It was slow enough and costly enough to make broad retail distribution impractical for anyone but large issuers.

NSMIA changed the architecture. It created a category called covered securities in Securities Act Section 18 and preempted state registration and merit review for anything falling inside it. Congress deliberately preserved state authority in two areas: the power to require notice filings and collect fees, and the power to investigate and prosecute fraud. That compromise is exactly why "we're preempted" is a half-answer.

Which exemptions are preempted — and which are not

Here is the map that determines your state workload. Note that the two exemptions founders most often assume are equivalent — Reg A+ Tier 1 and Tier 2 — sit on opposite sides of the line.

Reg D 506(b) and 506(c): preempted, but notice filings in every state you sell into

Both flavors of Rule 506 produce covered securities. States cannot make you register, review your deal, or condition the offering on their approval. What they can do — and nearly all do — is require that you file a copy of your Form D, submit a consent to service of process (Form U-2), and pay a fee. The prevailing deadline is 15 days after the first sale in that state, though specifics vary and some states impose late fees or require renewals for offerings that stay open.

The trigger is worth emphasizing because it is commonly misread: the obligation generally attaches on the first sale to a resident of that state, not on the first offer or the first ad impression. A 506(c) campaign advertising nationally does not owe 50 notice filings on day one. It owes a filing in each state where an investor actually closes. This is why the state list is an output of your investor distribution, not something you can finalize before the raise starts.

Reg CF: the narrowest state footprint of any exemption

Reg CF has the lightest state burden by design. Section 18(b)(4)(C) makes Section 4(a)(6) securities covered, and the statute further limits which states may even require a notice filing: generally the state of the issuer's principal place of business, and any state where purchasers of more than 50% of the aggregate amount of the offering reside. For a genuinely national Reg CF campaign with a diffuse investor base, no single state typically crosses the 50% threshold, so the practical filing footprint is often just the home state.

That is a real structural advantage of Reg CF, and it is one reason the exemption suits founders building a broad retail base. It is also why the Reg CF cost stack looks so different from Reg A+ — a comparison we break down in detail in our Reg CF vs Reg A+ cost and limit comparison.

Reg A+ Tier 1 vs Tier 2: the split that catches issuers

This is where a poorly-considered tier election becomes expensive. Tier 2 securities are covered securities when sold to qualified purchasers, and the states challenged that preemption and lost — the D.C. Circuit upheld the SEC's rule in Lindeen v. SEC (2016). Tier 2 issuers therefore face notice filings and fees, not merit review.

Tier 1 gets no preemption at all. A Tier 1 issuer that wants to sell nationally must clear each state's substantive review, which can mean merit standards in states that apply them. NASAA's Coordinated Review program exists to make this tractable by routing a single application through a lead-state process, but it is still a materially heavier lift than a Tier 2 notice filing.

The tradeoff is genuine rather than one-sided: Tier 1 avoids the ongoing audited financials and periodic reporting that Tier 2 requires, so a small, geographically concentrated raise can rationally choose Tier 1. But issuers who pick Tier 1 to save on audit costs and then plan a national ad campaign have chosen the worst of both worlds. If you are weighing this, our Reg A+ total cost breakdown puts the audit and legal figures next to each other.

Rule 504: the trap hiding inside Regulation D

Rule 504 sits in the same regulation as 506(b) and 506(c) and behaves nothing like them. It permits up to $10 million in a 12-month period, has no accredited-investor requirement in its base form, and — critically — produces no covered securities. There is no NSMIA preemption. Every state where you offer or sell requires registration or a specific state-level exemption.

Founders find 504 attractive on paper because the federal conditions look permissive. In practice, the absence of preemption makes multi-state 504 offerings burdensome enough that most issuers who need national reach end up at 506(c) or Reg CF instead. If someone is steering you toward 504 for an internet-marketed raise, ask them specifically how they intend to handle the state registrations.

How notice filings actually get made

Most Form D and Reg CF state notice filings now run through the Electronic Filing Depository (EFD), a NASAA-operated system that lets an issuer submit to participating states from one interface rather than mailing paper to each administrator. Not every state participates for every filing type, and a handful maintain their own portals or paper processes, so the EFD covers most but not all of the work.

Budget realistically. Per-state notice filing fees commonly land in the low hundreds of dollars, but they vary widely by state and by offering size, and a few states are conspicuously more expensive than the rest — New York has historically been an outlier. A raise closing investors across 30 states should expect the aggregate fee line to be meaningful but not deal-shaping; the bigger cost is usually the counsel time to track deadlines across a moving investor map. Confirm current fee schedules directly, since states adjust them and any figure published in an article ages quickly.

What preemption never covers: state antifraud authority

NSMIA preempted registration. It did not touch a state regulator's ability to investigate and bring an action for fraud or misrepresentation in connection with a securities offering. Every state retains that power over every offering sold to its residents, regardless of exemption or preemption status.

For anyone running a marketing-driven raise, this is the operative risk. Your ads, landing pages, webinars, email sequences, and founder social posts are all offering communications, and a state securities administrator can act on a misleading one even though that same state has no authority to review your deal. Preemption protects the structure of your offering; nothing protects sloppy claims.

The practical implication is that marketing review is not a federal-only exercise. The same discipline that keeps you inside SEC rules — no projected or guaranteed returns, no cherry-picked track record, complete and prominent risk disclosure, substantiation for every factual claim, consistent messaging between the ad and the offering document — is what keeps you out of state antifraud exposure too. We covered the specific language boundaries in what founders cannot say online under 506(c).

Where this intersects with your marketing plan

State compliance and investor acquisition are usually run by different people who never talk to each other, and that gap creates avoidable problems. A few connections worth making explicit:

• Your geo-targeting shapes your filing footprint. For Rule 506, sales drive notice filings. A campaign that concentrates spend in a few states produces a short, predictable filing list; one that runs nationally at low intensity produces a long one. Neither is wrong, but the compliance cost should be a known input to the media plan rather than a surprise afterward.
• Reg CF's 50% threshold rewards breadth. Because a state can require a notice filing when residents purchase more than half the offering, an unusually concentrated Reg CF investor base can pull an additional state into scope. Broad distribution is both a better outcome and a simpler one.
• Tier election should precede the campaign, not follow it. Deciding on Tier 1 and then discovering that a national campaign requires state-by-state clearance means either replanning the marketing or restructuring the raise. Both are expensive at that point.
• Every asset is an offering communication. Ads, decks, webinar scripts, and investor emails all fall inside both federal and state antifraud reach. Route them through the same review, once.

Frequently asked questions

Do I need to register in every state where my ad is seen?

No. For preempted offerings, states cannot require registration at all. For Rule 506, the notice filing obligation generally follows the first sale in a state, not an offer or an impression. Non-preempted offerings — Tier 1 and Rule 504 — are the ones where the reach of an offer genuinely matters, and those need state-specific analysis before you advertise.

Is a Reg D notice filing the same as registering?

No, and the difference is the entire point of NSMIA. A notice filing is administrative: you tell the state you sold there, provide a copy of your Form D and a consent to service of process, and pay a fee. The state does not review, approve, or pass judgment on your offering. Registration would involve substantive review and, in merit-review states, the possibility of rejection.

What happens if I miss a notice filing deadline?

Consequences are state-specific and escalate with the facts. Late fees are common; some states have processes for curing a late filing. It is a fixable administrative problem far more often than an existential one — but it is not something to leave undone, and the remedy depends on the state, so it is a question for your securities counsel rather than a marketing vendor.

Does Reg S trigger blue sky obligations?

Reg S offerings are made offshore to non-US persons and sit outside the US registration framework, so state blue sky filings are not the relevant question. The relevant question is the securities and marketing law of each jurisdiction where you actually solicit, which varies enormously. We walk through the structure in our Regulation S guide.

The short version

If you are running a Reg CF, 506(b), 506(c), or Reg A+ Tier 2 offering, no state can make you register or second-guess your deal — but states can and will require notice filings and fees where you sell, and every state can pursue you for a misleading claim. If you are running Reg A+ Tier 1 or Rule 504, preemption does not apply and each state is a separate gate you must plan for before the campaign, not during it.

None of this is legal advice, and it is not a substitute for securities counsel. State requirements, deadlines, and fee schedules change, and the right answer depends on facts specific to your offering. What this article should do is let you ask better questions — and stop your marketing plan and your compliance plan from being designed in separate rooms.
