A DST offering's terms reach the SEC long before they reach a brochure. They arrive as a Form D — a short notice filed no later than 15 calendar days after the first sale of the offering — and one checkbox on it, Item 6, marks whether the sponsor may advertise the raise publicly or must reach investors through relationships that already exist. That checkbox is the core of the DST Form D 506(b) vs 506(c) disclosure question, and it shapes what you can verify about a trust while a 45-day identification window is running.
One point of precision before the walkthrough: a Form D is a notice of an exempt offering. A Rule 506(b) or 506(c) DST is exempt from registration under the Securities Act — it is not registered with the SEC, and the SEC does not review or approve it. Filing the notice is a reporting obligation, not a seal of anything.
What follows is a field-by-field read of a DST's Form D: what each exemption requires the sponsor to do, and what the form leaves out entirely.
Why the exemption claimed on the filing matters
A Form D is not the offering document. The Private Placement Memorandum (PPM) carries the risk factors, the fee schedule, and the property-level detail. Form D is a notice — a compact filing that tells the SEC, and anyone reading EDGAR, which exemption the offering relies on plus a handful of numeric facts about the raise. Treating one as a substitute for the other is the most common misstep in reading a DST's public paper trail.
The 506(b)/506(c) distinction says something about how you were reached, not about what you were offered. A DST surfaced through a public webinar or a paid ad was very likely marketed under 506(c). One introduced by a registered representative on the strength of an existing relationship is more likely a 506(b) filing. Neither path carries any implication about asset quality, leverage, or sponsor track record. It describes the solicitation rules the raise operated under, nothing more.
What you'll need
- SEC EDGAR — the full-text search at sec.gov/edgar/search and the standard company search
- The issuing entity's name, which is frequently different from the marketing name of the trust
- The offering's PPM, if you have received one, for cross-reference
- A working grasp of accredited investor status, since both exemptions assume it for most DSTs even though 506(b) permits a limited number of non-accredited purchasers. Background on the terminology sits in the Top1031 Learn library.
Reading the filing, item by item
1. Pull the filing from EDGAR, not from the sponsor's website
Search by the issuing entity — usually the specific single-purpose Delaware statutory trust or its depositor, not the sponsor's parent brand. A trust marketed as "Main Street Multifamily DST" may file under a related LLC or series entity. Sponsor websites summarize filings; EDGAR carries the primary source.
Common mistake: searching the brand name only, finding nothing, and concluding no Form D exists when it sits under a subsidiary or series entity.
2. Check Item 6 for the exemption claimed
Item 6, "Federal Exemptions and Exclusions Claimed," carries checkboxes including Rule 506(b) and Rule 506(c). It is the most load-bearing field on the form. A 506(c) box means general solicitation was permitted and the issuer must take reasonable steps to verify that every purchaser is accredited — documentation such as tax returns, brokerage statements, or a written confirmation from a qualifying third party. A 506(b) box means no general solicitation, reliance on pre-existing relationships held by the issuer or its selling group, and in practice self-certification of accredited status through subscription documents.
Expected outcome: you know whether the raise required verified accreditation or accepted a representation.
3. Read Item 3 for related persons
Item 3 lists executive officers, directors, and promoters connected to the issuer. For a DST, that usually surfaces the sponsor's principals or the depositor entity's officers. Those names are the starting point for any background review; the filing itself makes no representation about them.
4. Check Items 11 and 13 for minimum investment and offering size
Item 11 reports the minimum investment accepted from an outside investor. Item 13 reports the total offering amount and the amount sold as of the filing date — not as of today. An amount filed two years ago may since have been amended upward or the raise closed. Any single filing is a snapshot.
Common mistake: reading the Item 13 total-sold figure as current. It speaks as of the date printed on that form, and sponsors amend Form D as a raise progresses.
5. Check Item 14 for investor counts
Item 14 breaks out the total number of investors who have already invested and, separately, the number of non-accredited investors. Rule 506(b) permits sales to up to 35 non-accredited purchasers, each of whom must be sophisticated — and their presence triggers specified information-delivery requirements for the issuer. Many DST sponsors limit offerings to accredited investors regardless of exemption, given the illiquidity of the interests. A non-accredited count on a DST filing is unusual enough to be worth reading against Item 6 rather than assumed to be a typo.
6. Check Item 12 for sales compensation
Item 12 names the persons receiving sales compensation and the broker-dealers they are associated with, along with the states where sales are solicited. Item 15 reports the dollar amount of sales commissions and finders' fees for the offering. Together they show that a selling group was compensated — a fact that sits apart from the sponsor-level fee load itemized inside the PPM.
7. Cross-reference the PPM for what Form D omits
Form D does not disclose acquisition fees, asset management fees, disposition fees, financing terms, distribution rates, or property-level financials. None of it lives on the notice. Every question in those categories is a PPM question.
8. Watch for Form D/A amendments
A Form D/A is an amended notice, typically triggered by a change in the offering amount, a change in previously reported information, or the annual amendment required while an offering remains ongoing. Several amendments across one trust's raise are routine and are not, on their own, a signal of anything.
Troubleshooting
- The filing isn't under the trust's marketing name. Search by the depositor entity or the sponsor's series LLC instead of the consumer-facing name.
- Item 13's offering amount looks stale. Look for a later Form D/A; the most recent amendment carries the current reported figures.
- A 506(b) filing appears to have been advertised publicly. That is a securities-law question about the issuer's conduct, not a data-reading question, and the form itself cannot resolve it.
- Item 14 shows a non-accredited investor on a DST you assumed was accredited-only. Confirm Item 6 first — 506(b) allows a limited number, subject to the sophistication and disclosure conditions.
- Full-text search surfaces a filing agent or law firm rather than the trust. Open the filing and read the issuer named in Item 1.
Tools and resources
- SEC EDGAR full-text search, which covers filings from 2001 forward, for locating the original Form D and any amendments
- The Top1031 directory of DST offerings for lining a trust up against its filing history
- The PPM itself for every fee, financing, and property question the notice does not touch
Where the Form D stops
A Form D confirms the exemption and the mechanics of the raise. It says nothing about fee load, financing structure, or the underlying real estate — all of which are disclosed in the PPM and the offering's supporting documents. Reading the two side by side is what turns a notice filing into usable context.
FAQ
What does Item 6 actually determine?
It records the Regulation D rule the offering relies on. Under 506(c), general solicitation and advertising are permitted, but the issuer must take reasonable steps to verify each purchaser's accredited status with documentation. Under 506(b), general solicitation is barred and accreditation is typically established by the investor's own representations.
Does a 506(b) filing indicate lower risk than a 506(c) filing?
No. The exemption governs how the sponsor was permitted to solicit investors. It carries no information about the property, the financing, or the risk profile of the interests being sold.
Where are DST Form D filings found?
On SEC EDGAR, searchable by the issuing entity's name — often the specific trust or its depositor rather than the sponsor's consumer-facing brand, which is why a brand-name search alone can come up empty.
One habit worth keeping
The Item 13 figure reads like a live raise counter. It isn't. It is a snapshot from the date printed on that specific filing, and the version a search engine surfaces first is not always the latest one. Checking the filing date before reading any number on the form prevents the most common misread of a DST's Form D.
