South Dakota: LLC Amendment and Legal-Name-Change Filing Requirements
The short answer
A South Dakota LLC may amend or restate its articles at any time. Unless the operating agreement provides another rule, every member must consent to an articles amendment; a member signs for a member-managed LLC and a manager signs for a manager-managed LLC. The filing states the exact company name, original filing date, and amendment, costs $60, and may take effect on filing or on a delayed date no later than the 90th day after filing.

| Governing law and covered public record | South Dakota LLC Act, SDCL ch. 47-34A; amend public Articles of Organization by Amended Articles or consolidate them through Restated Articles filed with Secretary of State (§ 47-34A-204) |
|---|---|
| Mandatory, permitted, and restatement routes | No general prompt-accuracy amendment duty in § 47-34A-204; articles may be amended anytime. Restatement anytime, signed/filed like amendment, headed as restated, and identifies present/former names plus initial filing date (§ 47-34A-204) |
| Legal name and availability | Legal-name change uses Amended Articles. Name needs LLC designator and distinguishability; current user consent/undertaking or final judgment may permit otherwise unavailable name. Separate fictitious-name statement is $10 and lasts 5 years (§§ 47-34A-105, 37-11-1) |
| Internal approval and private consents | Operating agreement may supply another rule; otherwise all members consent to articles amendment in member- or manager-managed LLC. Action may occur without meeting. No ordinary state-filing third-party consent, apart from name-conflict route (§§ 47-34A-103, -404.1) |
| Filing contents and attachments | Statute requires LLC name, original-articles filing date, and amendment. Current form also asks business ID, exact registered name, signer title/date, and optional email; no ordinary attachment. Restatement adds present name, every former name, and initial filing date (§ 47-34A-204; SOS form) |
| Signer, filing channel, and fee | Member signs for member-managed LLC; manager for manager-managed; court fiduciary if applicable; signer name/capacity adjacent; attorney-in-fact allowed and POA retained, not filed. Current published route is paper form. $60 amendment/restatement; $110 if amendment adds series authority (§§ 47-34A-205, -1206; SOS) |
| Effective time, delay, and rejection | Accepted record effective at filing/stated time that day or delayed time/date; delay after 90th day is cut back to day 90, and date without time means close of business. Secretary rejects for form noncompliance or unpaid fee and otherwise files and sends receipt (§ 47-34A-206) |
| Correction, change, report, and assumed-name alternatives | Articles of correction fix false/erroneous statement or defective signature and usually relate back, subject to reliance. Agent/office statement takes effect on filing and costs $10 without owner/governor approval. Annual/amended report handles report data; DBA filing is $10/5 years. LLC fee table lists no correction charge—confirm (§§ 47-34A-207, 59-11-11, -24; 37-11-1; SOS) |
| Post-filing records, registrations, and status effect | Accepted filing changes public articles; Act provides member/manager access to company records and written agreement but no amendment-specific internal-update checklist. Certificate of existence reports tax/fee and annual-report status. Tax, license, bank, contract, title, trademark, DBA, and foreign-registration updates remain separate (§§ 47-34A-208, -408) |

Requirements one by one
Amendment and restatement are always available
SDCL § 47-34A-204 permits an LLC to amend its articles at any time. The filed
record states the exact LLC name, the original articles filing date, and the
amendment. The Secretary of State form also asks for the business ID.
A restatement is filed and signed in the same manner. It is headed as restated
articles and identifies the present name, every former name, and the initial
articles filing date.
A legal-name change still has to satisfy the name statute
SDCL § 47-34A-105 requires an LLC designator and record distinguishability.
The Secretary of State may authorize an otherwise unavailable name when the
current user consents and undertakes to change its name, or when the applicant
delivers a qualifying final judgment.
An LLC doing business under another name uses the separate § 37-11-1
fictitious-name route. The current filing is $10 and renews every five years; it
does not replace the legal-name amendment.
Unanimity is the default even for manager-managed companies
Under § 47-34A-404.1, an articles amendment is one of the listed actions that
requires all-member consent in either management structure, and the action may
be taken without a meeting. The operating agreement can supply another rule
because § 47-34A-103 makes the statutory relationship rules control only to the
extent the agreement does not otherwise provide.
The signature is a different question from approval. A manager signs for a
manager-managed LLC and a member signs for a member-managed LLC after the
required authority exists.
The current published amendment route is a $60 paper form
Section 47-34A-205 requires the company record to be signed by the applicable
member or manager, with the signer's name and capacity adjacent. A court-
appointed fiduciary signs when the company is in fiduciary hands. An attorney-
in-fact may sign, and the company retains rather than files the power.
The current LLC forms page links the Amended Articles PDF without a separate
online amendment link. The filing fee is $60 for an ordinary amendment or
restatement. An amendment adding notice that the LLC may establish series costs
$110 under § 47-34A-1206.
The outside delayed date is the 90th day
Under § 47-34A-206, an accepted record takes effect at filing, at a stated time
that day, or at a delayed time and date. A delayed date without a time means
close of business. If the stated date falls after the 90th day, the statute
makes the record effective on day 90.
The Secretary of State rejects a record that fails the chapter's form
requirements or lacks the filing fee. Otherwise, the office files it and sends
a receipt for the record and fees. The current amendment form has no dedicated
delayed-effective field, so a delayed filing needs current-office confirmation.
Correction, agent, annual-report, and DBA filings do different work
SDCL § 47-34A-207 limits articles of correction to a false or erroneous
statement or defective signature. The correction describes the original record,
identifies the problem and reason, and supplies the correction. It generally
relates back, but for a relying person adversely affected it starts on filing.
The current LLC fee table does not list a separate correction charge.
A registered-agent or agent-address change uses the separate § 59-11-11
statement, needs no interest-holder or governor approval, takes effect on
filing, and currently costs $10. The annual or amended annual report carries
principal-office, agent, and applicable governor information. SDCL § 59-11-24
says an amended report supplements rather than replaces the required annual
report.
Public acceptance does not finish the internal and outside updates
The accepted filing changes the South Dakota public articles. SDCL § 47-34A-408
provides proper-purpose access to company records and a written-
demand right to a copy of any written operating agreement, but it states no
amendment-specific internal checklist.
Keep tax, license, bank, contract, property-title, trademark, fictitious-name,
and foreign-registration updates on separate worklists. Under SDCL § 47-34A-208,
a certificate of existence separately reports whether relevant state charges are paid and the
most recent annual report is filed.
The report-calendar alternative changes in 2027
Effective January 1, 2027, enacted HB 1102 and the future version of SDCL § 59-11-25
allow the annual report to use the formation-anniversary month or
January 31. A good-standing entity may switch
between those schedules through a change-of-filing-date form. That future rule
does not change the articles-amendment approval, contents, signer, fee, or
90-day effective-time rules.
What trips people up
The statute separates unanimous internal approval from the signature on the
public form. One member or manager may be the correct signer under § 47-34A-205,
but that signature alone does not replace the all-member default approval in §
47-34A-404.1.
Common questions
Can I request a certified copy of the accepted amendment?
Yes. SDCL § 47-34A-206(b) directs the Secretary of State to send a certified
copy of a requested record after the request and fee are received.
Can articles of correction attach the original record instead of describing it?
Yes. Section 47-34A-207 allows the correction to describe the record and its
filing date or attach a copy of the record.
