Qualifying is one thing. Proving it to a sponsor’s satisfaction is another, and the amount of proof required depends entirely on which exemption the offering is using — a distinction almost nobody explains to investors before they’re asked for tax returns.

The Two Exemptions

Rule 506(b) — The sponsor may not advertise or generally solicit. It can only approach people with whom it has a pre-existing, substantive relationship. In exchange for that restriction, the verification burden is light: the issuer may rely on your written representations, typically a subscription questionnaire in which you check the box for your qualifying pathway and sign. Up to 35 non-accredited but sophisticated investors are also permitted, though most sponsors avoid the extra disclosure obligations that come with them.

Rule 506(c) — The sponsor may advertise publicly. In exchange, it must take reasonable steps to verify that every purchaser is accredited. Your say-so is not enough.

If you’re being asked for documents, you’re in a 506(c) offering. If you’re being asked only to sign a questionnaire, you’re in a 506(b) offering. That single fact tells you a lot about how the sponsor is raising capital.

What “Reasonable Steps” Traditionally Meant

Rule 506(c) includes a non-exclusive safe harbor. Satisfy one of these and the issuer is deemed to have verified:

  • For the income test — IRS forms for the two most recent years (W-2, 1099, K-1, Form 1040), plus a written representation that you reasonably expect to meet the threshold this year.
  • For the net worth test — Asset documentation dated within the prior three months (bank, brokerage, and custodial statements; tax assessments for real estate) and a consumer credit report from at least one nationwide agency, to establish liabilities. Net worth requires both sides of the balance sheet, which is why the credit report shows up.
  • Third-party confirmation — A written letter, dated within the prior three months, from a registered broker-dealer, an SEC-registered investment adviser, a licensed attorney, or a CPA, confirming reasonable steps taken. This is the least invasive route and the reason “accredited investor letters” exist as a service.
  • Prior verification — If you were verified within the last three months by the same issuer, that carries forward.

What Changed in March 2025

The document-review burden had a chilling effect: sponsors overwhelmingly chose 506(b) and gave up the ability to advertise rather than ask investors for credit reports.

On March 12, 2025, the SEC’s Division of Corporation Finance issued a no-action letter establishing that a high minimum investment amount can itself constitute reasonable verification. The conditions:

  • A minimum investment of at least $200,000 for natural persons, or $1 million for legal entities (with a look-through figure for entities accredited solely because all their owners are)
  • Written representations that the purchaser is accredited and that the investment is not financed by a third party for the purpose of making it
  • The issuer has no actual knowledge of facts indicating otherwise

Binding capital commitments count toward the minimum. The practical effect: if you’re writing a $250,000 check into a fund using this route, you may never be asked for a tax return.

One caveat worth keeping in view. No-action letters are staff positions. They are not rules, they don’t have the force of law, and they can be revisited. Most sponsors have adopted the approach; a conservative one may still ask for documents, and is within its rights to.

What You Should Expect to Provide

Reasonable, in a normal 506(c) subscription:

  • A completed investor questionnaire naming your qualifying pathway
  • Either a third-party letter, or redacted financial statements, or acceptance of the high-minimum route
  • Identity documentation for AML/KYC — this is a separate legal requirement and is not negotiable
  • W-9 for tax reporting

What You Should Push Back On

  • Unredacted account statements. Account numbers, routing details, and holdings detail are not needed to establish a net worth figure. Redact them.
  • Login credentials to an aggregation service. Some platforms request read-only access to your accounts to automate verification. It’s convenient. It also hands a third party a live feed of your finances. A CPA letter accomplishes the same thing without the data exposure.
  • Open-ended data-sharing consent. “We may share your information with partners” is not consent to anything specific. Ask who, for what, and whether you can decline and still subscribe.
  • Verification before you’ve seen the offering documents. There’s no reason to establish your net worth to a sponsor whose PPM you haven’t read.

Privacy and Retention

Ask two questions before you send anything: how long the sponsor retains verification documents, and whether verification is handled in-house or by a third-party provider. If it’s a provider, you’re in that provider’s data environment too, under their retention policy and their breach exposure. That’s not a reason to refuse — most are legitimate and specialized — but it’s a reason to know the name.

Verification letters are customarily treated as valid for 90 days, which is why re-verification is routine on each new subscription rather than a sign of disorganization.

FAQ

Do I need a CPA letter to be an accredited investor?

No. A letter documents status for a 506(c) offering; it doesn’t confer it. Under 506(b), a signed questionnaire is typically sufficient.

How long is accredited investor verification good for?

Generally 90 days by market convention, after which sponsors typically re-verify.

Can a sponsor accept me without any documents?

Under 506(b), yes — written representations are generally sufficient. Under 506(c), the issuer must take reasonable steps, which since March 2025 may mean a high minimum investment plus representations rather than document review.

Who can write a verification letter?

A registered broker-dealer, an SEC-registered investment adviser, a licensed attorney, or a certified public accountant.

Is my information shared with the SEC?

No. Verification is conducted by the issuer for its own compliance file. The SEC does not maintain a registry of accredited investors.
