Key Takeaways
- South Dakota allows incoming LLC domestication directly (SDCL §47-34A-910 to §47-34A-913) — your LLC keeps its original formation date
- Filing fee: Not separately published for domestication specifically; by analogy to South Dakota's standard LLC formation fees, likely around $150 online or $165 by mail — confirm the exact domestication fee directly with the Secretary of State before filing
- No new EIN is needed. South Dakota's domestication statute (SDCL §47-34A-913, "Effect of domestication") follows the standard domestication-statute pattern of preserving continuity — the IRS treats your EIN as unchanged. Update your address on file with the IRS via Form 8822-B once your South Dakota registered agent is set.
- No. Domestication is self-executing under South Dakota law — your LLC's existence under its old state's law ends automatically once the South Dakota domestication becomes effective, so no separate withdrawal filing is required, and South Dakota's own filing doesn't condition acceptance on proof of a withdrawal elsewhere.
- Same-day LLC domestication filing available through LLC Attorney, at no markup on state fees
If your LLC is formed in another state but you want South Dakota to be its new legal home — for the tax environment or asset-protection reputation — domestication lets you make that move without dissolving the company and starting over.
This guide covers exactly how to domesticate an LLC into South Dakota in 2026 — the statute that authorizes it, the fact that there's no pre-made state form for it, the required Plan of Domestication, and what happens to your EIN and formation date.
What Is LLC Domestication?
Domestication (sometimes called continuance or statutory conversion) lets you move your LLC from one state to South Dakota without dissolving it and starting over. Done correctly, the LLC keeps its original formation date, its EIN, and its contracts — only its home state changes.
Can You Domesticate an LLC Into South Dakota?
Yes. South Dakota's LLC Act includes a statutory domestication provision (SDCL §47-34A-910 to §47-34A-913), so an out-of-state LLC can become a South Dakota LLC directly while retaining its original formation date.
How to Domesticate Your LLC in South Dakota
- Filing agency: South Dakota Secretary of State, Business Services Division
- Form: Articles of Domestication — South Dakota's standard LLC forms list does not include a pre-made fillable form for this filing, so you (or your attorney) must draft custom Articles of Domestication that satisfy SDCL §47-34A-912's content requirements
- Filing fee: Not separately published for domestication specifically; by analogy to South Dakota's standard LLC formation fees, likely around $150 online or $165 by mail — confirm the exact domestication fee directly with the Secretary of State before filing
- Processing time: 1-2 business days online; several additional days if filed by mail
- Certificate of Good Standing: Required from your current state, dated within 90 days of filing.
- Plan of domestication: A formal plan of domestication must be adopted and filed alongside the conversion paperwork.
- Member approval: SDCL §47-34A-911 ("Action on plan of domestication by domesticating limited liability company") governs how your LLC must approve the move, but doesn't set out one universal statutory percentage in the sections reviewed — follow your operating agreement's own domestication-approval threshold, and if it's silent, plan for unanimous member approval given how fundamental this change is.
What Happens to Your EIN, Contracts, and Formation Date?
Domesticating to South Dakota preserves your LLC's original formation date — the entity continues, it doesn't restart.
No new EIN is needed. South Dakota's domestication statute (SDCL §47-34A-913, "Effect of domestication") follows the standard domestication-statute pattern of preserving continuity — the IRS treats your EIN as unchanged. Update your address on file with the IRS via Form 8822-B once your South Dakota registered agent is set.
All existing contracts, bank accounts, licenses, and pending liabilities carry over automatically — South Dakota's domestication statute treats the South Dakota LLC as the same entity that existed under its prior state's law, not a new one stepping into its shoes.
Do I Need to Close My LLC in My Old State?
No. Domestication is self-executing under South Dakota law — your LLC's existence under its old state's law ends automatically once the South Dakota domestication becomes effective, so no separate withdrawal filing is required, and South Dakota's own filing doesn't condition acceptance on proof of a withdrawal elsewhere.
If your business keeps operating in the old state after moving its legal home to South Dakota — an office, employees, or regular in-state activity — you'll likely need to foreign-qualify in that state instead of maintaining it as your domestic entity. Check the old state's foreign-qualification requirements once the move is final.
When Do South Dakota's Taxes and Filings Start?
South Dakota's compliance obligations begin on the effective date stated in the Articles of Domestication. South Dakota has no state personal or corporate income tax, so the main ongoing obligation is the state's annual report filing due each year by the first day of the anniversary month of formation.
You'll typically owe a final-year return to your old state covering the period before the domestication took effect, prorated to the effective date — confirm the exact filing requirement with that state's tax agency, since this varies based on where your prior state was.
South Dakota's statute doesn't specify an exact maximum age for the Certificate of Good Standing — 90 days is the commonly cited practitioner estimate, not a confirmed statutory figure, so it's worth confirming directly with the Secretary of State if your certificate is close to that age.
How to Move Your LLC to South Dakota Step by Step
If You Do It Yourself
Step 1 — Confirm your LLC is in good standing in its current state.
South Dakota will require a Certificate of Good Standing from your current state, so resolve any lapsed filings there first.
Step 2 — Get member approval for the move.
SDCL §47-34A-911 ("Action on plan of domestication by domesticating limited liability company") governs how your LLC must approve the move, but doesn't set out one universal statutory percentage in the sections reviewed — follow your operating agreement's own domestication-approval threshold, and if it's silent, plan for unanimous member approval given how fundamental this change is.
Step 3 — File the domestication paperwork.
File with South Dakota Secretary of State, Business Services Division using the Articles of Domestication — South Dakota's standard LLC forms list does not include a pre-made fillable form for this filing, so you (or your attorney) must draft custom Articles of Domestication that satisfy SDCL §47-34A-912's content requirements, Not separately published for domestication specifically; by analogy to South Dakota's standard LLC formation fees, likely around $150 online or $165 by mail — confirm the exact domestication fee directly with the Secretary of State before filing.
Step 4 — Confirm your EIN and contracts carry over.
No new EIN is needed. South Dakota's domestication statute (SDCL §47-34A-913, "Effect of domestication") follows the standard domestication-statute pattern of preserving continuity — the IRS treats your EIN as unchanged. Update your address on file with the IRS via Form 8822-B once your South Dakota registered agent is set. All existing contracts, bank accounts, licenses, and pending liabilities carry over automatically — South Dakota's domestication statute treats the South Dakota LLC as the same entity that existed under its prior state's law, not a new one stepping into its shoes.
Step 5 — Appoint a registered agent in your new state.
South Dakota calls this role a "Registered Agent" — required before or as part of the domestication filing.
Step 6 — Handle your old state's final obligations.
No. Domestication is self-executing under South Dakota law — your LLC's existence under its old state's law ends automatically once the South Dakota domestication becomes effective, so no separate withdrawal filing is required, and South Dakota's own filing doesn't condition acceptance on proof of a withdrawal elsewhere. You'll typically owe a final-year return to your old state covering the period before the domestication took effect, prorated to the effective date — confirm the exact filing requirement with that state's tax agency, since this varies based on where your prior state was.
Step 7 — Update your tax and compliance calendar.
South Dakota's compliance obligations begin on the effective date stated in the Articles of Domestication. South Dakota has no state personal or corporate income tax, so the main ongoing obligation is the state's annual report filing due each year by the first day of the anniversary month of formation.
Step 8 — Watch for South Dakota-specific domestication traps.
The single most important thing to know about domesticating an LLC into South Dakota: even though the statute clearly authorizes it, the Secretary of State's standard LLC forms list does not include a pre-made Articles of Domestication form. You (or your attorney) have to draft a custom document that satisfies SDCL §47-34A-912's required content — a meaningfully different experience than filling out a state PDF. South Dakota also requires a formal Plan of Domestication as a separate document before filing, unlike Nevada, which skips that extra step.

When Should You Talk to an Attorney About Moving Your LLC to South Dakota?
Talk to an attorney before domesticating your LLC to South Dakota given the lack of an official state form — you'll want the custom Articles of Domestication and Plan of Domestication drafted correctly the first time, especially if your operating agreement doesn't clearly address domestication approval or you have multiple members.
Is South Dakota a State Where Domestication Complexity Matters More?
South Dakota is a state where the statute clearly authorizes domestication (SDCL §§47-34A-910 to 913), but the Secretary of State provides no ready-made fillable form for it — unlike a standard LLC formation, you're drafting custom Articles of Domestication that must independently satisfy §47-34A-912's content requirements, plus a separate formal plan of domestication that South Dakota (unlike Nevada) requires as its own document. Getting the content of both right without an official template is where LLC Attorney's experience with South Dakota specifically matters most.
