The regulatory landscape for private fund managers conducting Regulation D Rule 506(c) offerings shifted dramatically over the past twelve months — and if you haven't updated your compliance procedures, your next capital raise could be at risk. The most significant change came in March 2025, when the U.S. Securities and Exchange Commission (SEC) issued a landmark no-action letter that fundamentally reimagined how sponsors can verify accredited investor status under Rule 506(c) of Regulation D. That guidance — combined with new filing deadlines, AML/CFT postponements, and proposed "small entity" redefinitions — creates both new opportunities and new obligations for fund managers in 2026.

For years, one of the primary reasons sponsors avoided Rule 506(c) was the burdensome third-party verification requirement. Unlike Rule 506(b), which permits investors to self-certify their accredited status, 506(c) historically required fund managers to obtain IRS tax forms, bank statements, brokerage records, or letters from CPAs, attorneys, or registered investment advisers. This friction kept many sponsors from leveraging 506(c)'s most powerful advantage: the legal right to engage in general solicitation and advertising — including public websites, media placements, and broad email campaigns — to attract new investors.

The SEC's new guidance changes that calculus entirely. This article breaks down every material regulatory development fund managers operating under Rule 506(c) need to understand heading into 2026: what changed with accredited investor verification, how the five-year re-verification rule works, what the latest compliance calendar deadlines are, and how to update your offering documents and subscription agreements before your next raise.

The March 2025 No-Action Letter: The Biggest Shift in 506(c) History

On March 12, 2025, the SEC Division of Corporation Finance issued a no-action letter — responding to a request from Latham & Watkins LLP — that represents the single most significant development in Rule 506(c) compliance since the rule's adoption following the JOBS Act of 2012. The letter, published directly on SEC.gov, confirmed that issuers can satisfy the "reasonable steps" verification requirement through investor self-certification — provided specific minimum investment thresholds are met.

The SEC Staff also published two new Compliance and Disclosure Interpretations (C&DIs) on the same date that further clarified how issuers should interpret the verification requirement in everyday practice. Together, the no-action letter and C&DIs create a clear, practical roadmap that sponsors have lacked since Rule 506(c) became effective in September 2013.

What "Reasonable Steps" Now Means Under the New Guidance

Prior to March 2025, fund managers had to rely on the SEC's 2012 non-exclusive list of acceptable verification methods — a list that required gathering and retaining sensitive investor documents. According to Kirkland & Ellis, those methods included obtaining IRS forms, bank or brokerage statements, credit reports, or written letters from attorneys, CPAs, broker-dealers, or registered investment advisers. For many sponsors, the friction and cost of gathering these documents made 506(c) unattractive compared to 506(b).

Under the new guidance, an issuer will be deemed to have taken "reasonable steps" to verify accredited investor status if two conditions are met simultaneously:

1. Minimum Investment Threshold: The investor commits at least $200,000 in cash (or the right to call cash) if they are a natural person, or at least $1,000,000 if they are a legal entity (such as a trust, LLC, or corporation). As confirmed by Reliant Fund Services, the invested capital must not be financed by a third party specifically for the purpose of making the investment.
2. Written Self-Certification: The investor furnishes a written representation — included in the subscription agreement or a separate certificate — affirming that (a) they qualify as an accredited investor and (b) the funds are not financed by a third party for investment purposes. Both conditions must be satisfied together, not independently.

Why the SEC Made This Change

The rationale behind the guidance connects directly to one of SEC Chairman Paul S. Atkins' stated priorities. According to Carta's 2026 analysis, Chairman Atkins outlined in the SEC's Spring 2025 Unified Regulatory Agenda that a core theme is to "reduce compliance burdens and facilitate capital formation, including by simplifying pathways for raising capital and investor access to private businesses." The no-action letter is a direct product of that deregulatory direction.

Historically, 506(c) underperformed relative to its potential. Data from the SEC Office of the Advocate for Small Business Capital Formation shows that from July 2023 to June 2024, pooled investment funds raised approximately $1.7 trillion under Rule 506(b) versus only $125 billion under Rule 506(c) — despite 506(c)'s ability to use general solicitation. The verification burden was the single largest barrier cited by sponsors avoiding 506(c). The new guidance is designed to close that gap.

The Five-Year Re-Verification Rule: What It Means for Repeat Investors

One of the most practically significant — and underreported — aspects of the SEC's 2025 guidance involves how fund managers handle existing investors across subsequent fund offerings. Prior to this guidance, many sponsors felt compelled to re-verify every investor's accredited status for each new fund launch or follow-on capital raise under 506(c), even for investors who had been investing with them for years.

As Eric Schultz, founder of Reliant Fund Services, explained in Family Wealth Report, the new guidance confirms that if an investor has already been verified as accredited within the last five years, the fund manager can rely on that verification for a subsequent offering — provided there is no reason to believe the investor's status has changed.

Practical Implications for Fund Administrators

This change has cascading effects on how fund operations are managed. Fund administrators can now maintain and reference historical verification files, track verification dates, and systematically determine when re-verification is or is not required. This eliminates duplicate due diligence for established LP relationships and meaningfully reduces administrative overhead on follow-on funds. Key operational changes to implement include:

• Verification date tracking: Implement a CRM or fund administration system field that logs the date of each investor's most recent verified accreditation and flags investors approaching the five-year lookback limit.
• No-change confirmation: For investors within the five-year window, include a brief affirmation in subscription documents that the investor's financial circumstances have not materially changed since last verification.
• Third-party administrator coordination: If you work with a fund administrator, update your service agreement to include verification date tracking as a standard deliverable.
• Documentation retention: Maintain original verification files for the entire period the investor remains active in any of your funds, plus a reasonable run-off period. The SEC's recordkeeping rules under Regulation D remain in effect.

Schultz noted that this change is especially impactful for emerging fund managers who launch multiple sequential funds, as the compliance cost of re-verifying a growing LP base across every new vehicle was previously one of the most significant hidden costs of operating under 506(c).

506(c) vs. 506(b) in 2026: Reassessing Your Offering Strategy

The SEC's new guidance fundamentally changes the cost-benefit analysis of choosing between Rule 506(b) and Rule 506(c). Fund managers who defaulted to 506(b) primarily to avoid verification friction should now re-evaluate their offering structure — particularly if they have minimum investment thresholds at or above the new safe harbor levels.

Reed Smith's analysis notes that private fund sponsors who already impose minimum commitments at or above the $200,000 or $1 million thresholds should find Rule 506(c) "considerably more attractive" under the new guidance. At the same time, managers who raise capital primarily from long-standing relationships with non-accredited sophisticated investors, or whose minimums fall below the threshold, may still find 506(b) the appropriate vehicle.

When 506(b) Still Makes Sense

Despite the improvements to 506(c), Rule 506(b) remains the right choice in several scenarios. Vector AIS identifies three situations where 506(b) retains a structural advantage: when a fund needs to accommodate up to 35 non-accredited but sophisticated investors; when the manager has deep pre-existing relationships with investors and has no need or desire to expand through advertising; and when minimum investment levels fall below the $200,000 / $1,000,000 thresholds required for the new self-certification path.

Key 2026 Compliance Deadlines Every Fund Manager Must Track

Beyond the verification guidance, 2026 brings a series of material filing deadlines and regulatory postponements that affect fund managers across asset classes. Kirkland & Ellis's 2026 compliance calendar and Lexology's annual reporting guide both highlight the following critical dates and developments.

Form PF Filing — Delayed to October 1, 2026

The SEC and CFTC have delayed the compliance date for the amended Form PF until October 1, 2026. During the interim period, the agencies are conducting a substantive review of Form PF to determine whether to take further action with respect to the form's content or the entities required to file it. For large hedge fund advisers — those managing at least $1.5 billion in regulatory assets under management attributable to hedge funds — quarterly update filings remain due within 60 days of each quarter-end. For 2026, those dates are June 1, August 31, and November 30 (adjusted to the next business day as applicable).

AML/CFT Program Requirements — Postponed to January 1, 2028

One of the most significant compliance postponements for fund managers in 2025-2026 involves FinCEN's anti-money laundering and countering the financing of terrorism (AML/CFT) program rule. Day Pitney's compliance guide confirms that FinCEN has postponed the effective date of the final rule requiring SEC-registered investment advisers and exempt reporting advisers to adopt AML/CFT programs, file suspicious activity reports (SARs), and comply with certain recordkeeping requirements. The new effective date is January 1, 2028. Importantly, FinCEN is also revisiting the scope of the rule, meaning further changes may occur before 2028.

Form ADV Annual Amendment

For registered investment advisers (RIAs) and exempt reporting advisers with a December 31 fiscal year-end, the annual updating amendment to Form ADV — including updates to the brochure, brochure supplement, and Form CRS/Part 3 — was due by March 31, 2026. Advisers must also confirm the timely delivery of updated brochures or summaries of material changes to existing clients and delivery of updated Form CRS to retail investors.

Regulation S-P (Safeguards Rule) — Now in Effect for Smaller RIAs

Smaller SEC-registered investment advisers (those with less than $1.5 billion in assets under management) were required to implement their written incident response programs and related safeguards under the amended Regulation S-P by their applicable compliance date in early 2026. This includes investor notice obligations for certain covered data incidents and procedures for oversight of service providers. Larger RIAs ($1.5 billion or more in AUM) were already required to comply as of December 3, 2025.

EDGAR Next Enrollment — Mandatory for All Filers

All EDGAR filers must be enrolled in EDGAR Next — the SEC's updated system for EDGAR account access and management — in order to submit any EDGAR filings. Kirkland & Ellis warns that enrollment requires filing a Form ID application, which must be signed and notarized, and that onboarding delays are possible. Fund managers who have not yet enrolled should do so immediately ahead of any upcoming filing deadline.

Proposed "Small Entity" Redefinition: What It Means for Emerging Managers

On January 7, 2026, the SEC published a proposed rule that would significantly raise the threshold for classifying an investment adviser as a "small entity" under the Regulatory Flexibility Act (RFA). The proposal, analyzed on Free Writings & Perspectives, would amend Rule 0-7 under the Investment Advisers Act of 1940 to raise the regulatory assets under management (RAUM) threshold from $25 million to $1 billion for identifying an investment adviser as a "small entity."

The practical implication: far more emerging and mid-size fund managers would now fall outside the "small entity" classification, meaning new SEC rules would require full regulatory flexibility analyses before being applied to them. This could slow the pace of burdensome new regulations affecting the mid-market private fund space — a net positive for most 506(c) fund managers.

To illustrate the magnitude of the proposed change: the proposal notes that the share of investment advisers classified as "small entities" under the current threshold has fallen from approximately 75% of all registered advisers in 1998 to just 3% of 15,909 total registered investment advisers in 2025 — driven by the dramatic growth in assets under management across the industry over the past two decades. The 1982-era thresholds are simply no longer reflective of market realities.

How to Update Your Offering Documents and Compliance Procedures

Taking advantage of the SEC's new verification guidance requires deliberate updates to your legal documents and internal compliance processes. The changes are not automatic — fund managers must actively incorporate the new framework before conducting any 506(c) offering. Here is a practical action plan.

Step 1: Review and Update Subscription Agreements

Your subscription agreement is the primary vehicle through which the new self-certification framework is operationalized. Reed Smith recommends updating subscription agreements to include two specific new provisions: (1) the required self-certification language confirming accredited investor status, and (2) an explicit representation that the investment commitment is not financed by a third party for the purpose of making the investment. Your fund counsel should draft this language carefully to align with the exact conditions specified in the no-action letter.

Step 2: Assess Your Minimum Investment Thresholds

If your current fund minimum falls below $200,000 for individuals or $1,000,000 for entities, you face a decision: retain the current minimum and continue using traditional verification methods, or modestly raise the minimum to access the new self-certification safe harbor. Reed Smith advises sponsors to evaluate whether modestly higher minimums could unlock the benefits of 506(c) without deterring target investors — a fund-specific analysis that weighs investor demographics against the administrative cost savings of streamlined verification.

Step 3: Build a Verification Date Tracking System

The five-year re-verification window requires a systematic approach to tracking investor verification dates. At minimum, your CRM or investor management platform should log the date each investor was last verified, their verification method, the documents or representations obtained, and a flag or reminder when their verification approaches the five-year expiration. Many fund administrators now offer this as a standard module — confirm with your administrator that it is configured and active.

Step 4: Update Your Private Placement Memorandum (PPM)

Your PPM should accurately describe the verification procedures you will use. If you are transitioning from traditional third-party verification to the new minimum investment / self-certification path, update the relevant sections of the PPM accordingly. Investors and their counsel will review this document, and consistency between the PPM and subscription agreement is essential for legal enforceability.

Step 5: Ensure Ongoing Marketing Rule Compliance

Critically, as Vector AIS emphasizes, if your fund is managed by an SEC-registered investment adviser, all marketing materials used in connection with your 506(c) offering must comply with Rule 206(4)-1 — the SEC Marketing Rule — under the Investment Advisers Act of 1940. The Marketing Rule contains specific restrictions on the use of hypothetical performance data, target return projections, third-party endorsements, testimonials, and case studies. The no-action letter eases verification, but does not relax Marketing Rule obligations.

The Broader Regulatory Direction: What's Coming Next

Fund managers should view the March 2025 no-action letter not as a one-off event, but as a signal of the SEC's broader regulatory posture under Chairman Atkins. The deregulatory direction — focused on reducing compliance friction while expanding capital formation — suggests several additional changes may follow. Carta's 2026 analysis indicates the SEC's current view is oriented toward expanding capital formation, including potentially broadening the accredited investor definition itself.

Two themes are worth watching. First, the SEC's ongoing review of Form PF's substance and scope — underway through the October 2026 compliance delay — may result in a leaner, less burdensome reporting framework for private fund advisers. Second, FinCEN's revisitation of the AML/CFT rule's scope before the 2028 effective date could result in further carve-outs or exemptions for smaller fund managers.

The practical implication for fund managers: build compliance systems that are adaptable, not static. Document your current verification procedures thoroughly, track regulatory guidance on a quarterly basis through sources like SEC.gov's rulemaking page, and maintain a relationship with qualified securities counsel who can alert you to material guidance updates as they occur.
