Subscription Booklet Checklist: Questionnaires, KYC and Signatures

A subscription booklet is the set of documents an investor fills in, signs and returns to commit capital to a private fund or a private offering. It contains the subscription agreement, in which the investor agrees to buy an interest and makes representations; an investor questionnaire that establishes the investor’s legal status; tax certification forms; know-your-customer and anti-money laundering materials; and the signature pages for the agreement and the governing document. The GP or issuer accepts the booklet, countersigns, and the investor becomes a limited partner or member at the next closing.

The checklist below runs in the order a reviewer at fund counsel or the administrator works: complete, eligible, verified, signed.

What should a subscription booklet checklist include?

That list maps to the “Subscription and closing” folder of our raise checklist, which holds 6 documents for a fund raise. The subscription documents use case covers how sponsors run the closing itself.

What are the parts of a subscription booklet?

Formats vary by law firm, but almost every booklet has the same five parts. The table shows what each part does and who usually reviews it.

Real estate syndications and company private placements use a shorter version of the same packet: a subscription agreement, an accredited investor questionnaire, a W-9 and a signature page for the operating agreement. Funds that rely on section 3(c)(7) or charge a performance fee need the longer questionnaire.

Which investor status questions are in the questionnaire?

This is the part of the booklet with the most legal weight. Each tick box connects to a specific rule, and a wrong answer can affect the fund’s own exemption. The thresholds below are the ones in the rules as we write; several are adjusted over time, so check the current figure with counsel.

Entities have their own tests. An entity is commonly accredited if it has total assets over $5 million and was not formed to make this investment, if all its equity owners are accredited, or if it owns investments over $5 million. Family offices with $5 million or more in assets can also qualify. The glossary entry on qualified purchasers explains how the investments test is counted, and the accredited investor entry covers the full list of categories.

Why the look-through questions matter

A 3(c)(1) fund is limited to 100 beneficial owners (a qualifying venture capital fund may have up to 250, subject to a capital cap the SEC indexes for inflation). If another fund or a company formed to invest buys a large stake, the rules may count its owners instead of the entity itself. That is why booklets ask whether the investor was formed for the purpose of investing, whether it is itself an investment company, and what share of its assets this commitment represents. Answer these questions carefully; a wrong answer can take the fund over its owner limit.

ERISA and the 25% test

Under the Department of Labor’s plan asset rule, if benefit plan investors hold 25% or more of any class of equity in the fund, ignoring interests held by the GP and its affiliates, the fund’s assets can be treated as plan assets and the manager becomes an ERISA fiduciary. The questionnaire asks each investor whether it is a benefit plan investor and, for entities such as funds of funds, what percentage of their own capital comes from plans. The administrator tracks the running total at every closing.

What KYC and AML documents does each investor type owe?

Registered investment advisers are not yet under a FinCEN anti-money laundering program rule: FinCEN adopted one in 2024 and has since delayed its effective date to January 1, 2028. Funds collect KYC anyway, because administrators, banks and placement agents require it, and because sanctions screening applies to every US person now. Every investor’s name, and every listed owner’s, should be screened against the OFAC Specially Designated Nationals list before acceptance.

The 25% ownership and single control person thresholds mirror the federal customer due diligence rule for banks and broker-dealers at 31 CFR 1010.230. Many administrators apply a lower ownership threshold for investors from higher-risk countries.

How does a booklet move from issue to acceptance?

Allow two to four weeks between sending booklets and the target closing date. Individuals often return them within days; institutions with their own legal review and signature committees take longer, and IRA custodians run their own queue. Set a booklet deadline about ten business days before the closing so that review and corrections fit.

What are the most common subscription booklet errors?

Every administrator keeps its own list, but the same handful of issues returns across funds and syndications. Fix them in the booklet design, not in follow-up emails.

What about Rule 506(c) verification?

In a 506(b) offering, the issuer may rely on the investor’s questionnaire answers, unless it has reason to believe they are wrong. A 506(c) offering permits general solicitation but requires the issuer to take reasonable steps to verify accredited status. The rule lists non-exclusive methods: reviewing IRS forms for the last two years for income, reviewing bank and brokerage statements and a credit report dated within the prior three months for net worth, or obtaining a written confirmation from a registered broker-dealer, registered investment adviser, licensed attorney or CPA. In March 2025, SEC staff also said in a no-action letter that a high minimum investment (at least $200,000 for individuals and $1 million for entities), combined with written representations and no contrary facts, can be a reasonable step. If you rely on that approach, have counsel document it.

Verification letters and statements are sensitive. Keep them in the investor’s private folder, never in a shared one. Form D is due within 15 days after the first sale, and the date of the first sale is commonly the date the first investor becomes irrevocably committed, so the booklet’s acceptance date matters for the filing. See 17 CFR 230.506 for the text of the rule.

How should the data room handle subscription documents?

The blank booklet can sit in a shared folder. Completed booklets cannot: they hold tax numbers, ID scans, bank details and net worth. Give each investor a private folder where only they, their counsel, your counsel and the administrator can see the papers. The matrix below shows a common setup.

Most sponsors still route the actual signature through a dedicated e-signature tool, which US law treats as valid for most contracts under the federal ESIGN Act. The room then holds the executed copy. Two features help most here: 2-step verification on investor logins, since completed booklets contain personal data, and an activity log, so IR can see who downloaded the blank booklet but has not uploaded a completed one. The fundraising data room ranking scores rooms on permission control and investor onboarding, the two criteria that matter most for this folder.

What happens after acceptance?

Once the GP countersigns, the investor’s commitment is fixed and the first capital call follows, often at or shortly after the closing. The booklet’s commitment amount drives every call notice for the life of the fund. The calculator shows how a commitment turns into calls over the investment period.

Keep the accepted booklet, the KYC file and the side letter together in the investor’s folder after the closing. They are the first things the auditor and any later secondary buyer will ask for. The side letters use case covers the MFN election that usually follows the final close, and the guide to the fund data room index shows where folder 10 sits in the wider room.
