When to Amend Form D: Rule 503 Rules for Sponsors

You must amend Form D in three cases: to correct a material mistake of fact or error, to reflect a change in the information you reported, and once a year while the offering is still going. Rule 503(a)(3) lists the changes that need no amendment, including the amount sold, the number of investors and an increase in the offering amount of 10% or less.

This guide walks through each trigger, the exceptions, and how to file the amendment on EDGAR. It builds on our guide to filing Form D. Rules are as of October 2026.

When does Rule 503 require a Form D amendment?

Rule 503(a)(3) gives three triggers:

A material mistake. Correct a material mistake of fact or error in the earlier notice as soon as practicable after you discover it.
A change in the information. Reflect a change in what you reported as soon as practicable after the change, unless the change is on the exception list below or happens after the offering ends.
The annual amendment. File on or before the first anniversary of the original notice or your most recent amendment, if the offering is continuing at that time.

You may also file an amendment at any time, even when none is required (Rule 503(a)(2)). A voluntary amendment can be useful when you want the public record to match the final amounts.

Which changes do not need an amendment?

Rule 503(a)(3)(ii) lists changes that need no amendment. The SEC's compliance guide repeats the same list:

The address of a related person, or their relationship to the issuer
The issuer's revenues or aggregate net asset value
An increase in the minimum investment, or a decrease of 10% or less in total since the last filing
Any address or state of solicitation for a person receiving sales compensation (Item 12)
A decrease in the total offering amount, or an increase of 10% or less in total since the last filing
The amount sold or the amount left to sell
The number of non-accredited investors, as long as it does not go above 35
The total number of investors
A decrease in sales commissions, finders' fees or payments to executive officers, directors or promoters, or an increase of 10% or less in total since the last filing

Also, no amendment is required for a change that occurs after the offering terminates.

Do you need to amend Form D for this change?

Here is how the rule applies to changes that come up in apartment deals. Your securities attorney should confirm the answer for your facts.

Change	Amend?	Why
You sold more units in the offering	No	Amount sold is on the exception list
More investors joined	No	Total investor count is on the exception list
Offering amount rose 8% since the last filing	No	An increase of 10% or less is excepted
Offering amount rose 15% since the last filing	Yes	Above the 10% threshold
You added a new managing member or executive officer	Generally yes	A new related person is a change in Item 3; only address and relationship changes are excepted
A managing member moved	No	Address changes of related persons are excepted
You hired someone paid to find investors	Generally yes	New sales compensation information in Item 12
You found a wrong date of first sale	Yes, if material	Correct a material mistake as soon as practicable
The offering is still open 12 months later	Yes	The annual amendment

Does raising the offering amount require an amendment?

Only if the total increase since your last filing is more than 10%. The test is cumulative, so several small increases can add up.

A made-up example: a sponsor files Form D for a $2,000,000 offering. Demand is strong, so the sponsor raises the offering to $2,150,000. That is an increase of $150,000, or 7.5%, so no amendment is required. Later the sponsor raises it again to $2,250,000. Together the changes are $250,000, which is 12.5% of the $2,000,000 in the last filing, so an amendment is now due as soon as practicable.

Before you raise the amount, check your offering documents and escrow terms too. A bigger raise can change the minimum raise and closing plan and what investors were told.

When is the annual amendment due?

On or before the first anniversary of the most recent Form D filing, if the offering is continuing at that time. If you filed the original notice on March 3, 2026 and filed nothing since, and you are still accepting investors, the amendment is due on or before March 3, 2027. If you filed an amendment in August 2026, the clock restarts from that date.

Most single-property raises close within a year, so the annual amendment often never comes up. It matters for a deal that keeps selling for a long time, or for a fund that raises in stages.

Rule 503(a)(4) adds one more point: every amendment must give current information for every item on Form D, regardless of why you file it. An annual amendment is a full update.

How do you file a Form D amendment on EDGAR?

Sign in. An authorized person signs in to EDGAR Online Forms with their own Login.gov credentials. See our guide to EDGAR access for a new LLC.
Choose Form D and mark it as an amendment. The form has a box to say the filing is an amendment rather than a new notice.
Update every item. Bring the amounts sold, investor counts, related persons and sales compensation up to date, not only the item that triggered the filing.
Sign and submit. A person duly authorized by the issuer signs (Rule 503(b)(2)). The SEC charges no fee for a Form D or an amendment.
Check the states. Some states want a copy of the amendment and some charge for it. For example, NASAA's fee schedule as of October 1, 2026 shows Oregon charging $100 for an amendment that increases the offering amount. See blue sky notice filings.

Once filed, a Form D is public and generally cannot be withdrawn, according to the SEC's Form D FAQ. Read what the public sees in is Form D public.

How DoorRaise fits in

DoorRaise helps sponsors raise equity for apartment buildings with 5+ units from their friends and followers under Rule 506(b) or 506(c). It prepares the standard offering documents, forms the LLC, files Form D and state notices, and verifies accredited investors for 506(c) deals. Escrow is at Enterprise Bank & Trust, an FDIC-insured bank, and investors fund by wire only. Fees are $1,500 at setup (non-refundable), $5,000 at closing (only if the deal closes) and $3,500 a year, with no percentage of the raise and no part of the promote. DoorRaise is not a law firm, broker-dealer, investment adviser, funding portal or bank, so your own attorney decides whether a change is material.

FAQ

Is there a fee to amend Form D?

The SEC charges no fee for a Form D notice or an amendment. Some states charge a fee when they receive an amendment, so check each state where you filed.

Does a capital call need a new Form D?

No. The Form D instructions say a mandatory capital commitment call is not a new offering; it is made under the original offering, so no new Form D is required. See what a capital call is.

What if I missed an amendment?

File it as soon as you can with current information in every item. Filing Form D is a requirement of Rule 503 but, in the SEC staff's view, not a condition of the Rule 506 exemption. Read what happens if you file Form D late.

Do I amend Form D after the deal closes?

Not for changes that happen after the offering terminates. You may still file a voluntary amendment if you want the public record to show the final amounts.

Next step: read what happens if you file Form D late so a missed date does not turn into a bigger problem.
