BOI reporting in South Dakota
Under FinCEN's final rule of August 14, 2026, BOI reporting requirements changed permanently for South Dakota businesses. South Dakota-formed LLCs and corporations are exempt. Only foreign-formed entities registered to do business in South Dakota must file BOI with FinCEN.
US entities are permanently exempt from BOI under FinCEN's final rule of August 14, 2026.
If you formed your business in South Dakota (LLC, corporation, nonprofit), you no longer need to file BOI, and FinCEN has made that permanent.
FinCEN's final rule of August 14, 2026, which made permanent the interim rule of March 26, 2025:
- Removed BOI reporting for "domestic reporting companies" · entities formed in any US state including South Dakota.
- Maintained BOI requirements only for foreign-formed entities registered to do business in any US state.
- Excluded US persons from being reported as beneficial owners by any entity.
South Dakota-formed entities: no BOI filing required
If your LLC, corporation, or nonprofit was formed in South Dakota by filing Articles of Organization or Articles of Incorporation with the South Dakota Secretary of State, you are exempt from federal BOI reporting under FinCEN's final rule of August 14, 2026.
South Dakota does not have a state-level beneficial ownership law as of 2026. Federal BOI under FinCEN's final rule of August 14, 2026 is the only beneficial ownership filing currently applicable in South Dakota.
Foreign-formed entities operating in South Dakota: must file
If your entity was formed under the laws of another country (UK Ltd, Canadian Inc, Singapore Pte Ltd, etc.) and you registered to do business in South Dakota via foreign qualification, BOI filing is required:
- Deadline: 30 calendar days from the effective date of South Dakota foreign qualification.
- What to file: Beneficial owner information for each non-US person beneficial owner. US persons are NOT reported.
- Where to file: FinCEN BOSS at boiefiling.fincen.gov (free).
- Penalty for non-filing: Up to $606/day in civil penalties, plus criminal penalties up to $10,000 + 2 years imprisonment.

I formed an LLC in South Dakota. Do I need to file BOI?
No. As of 2026, South Dakota-formed LLCs and corporations are exempt from the federal beneficial-ownership (BOI) report, because FinCEN's final rule of August 14, 2026 permanently removed the requirement for US-formed companies. You do not file federally just for being a South Dakota entity. We confirm your specific situation so you are not filing something that is no longer required.
I am a foreign company registered in South Dakota. Do I file?
Yes. The 2025 rule kept BOI reporting for foreign-formed entities registered to do business in a US state, so a non-US company qualified in South Dakota generally still reports its beneficial owners to FinCEN. We help foreign-registered entities file the South Dakota-triggered BOI report correctly and on time so the penalties do not apply.
What if I am a US citizen but own a foreign company operating in South Dakota?
The reporting obligation follows the entity, not just your citizenship: a foreign-formed company registered in South Dakota generally still files even if you personally are a US citizen, while a US-formed company you own is exempt. We sort out which of your entities report based on where each was formed, not only who owns them.
What counts as beneficial ownership information?
BOI is the identifying details, name, birthdate, address, and an ID number, of the individuals who ultimately own or control a company, which FinCEN collects to combat illicit finance. Even where you do not file federally, banks ask for similar information under their own know-your-customer rules. We explain what counts as a beneficial owner for your South Dakota entity.
Do the old 30 or 90 day BOI deadlines still apply?
Not for US-formed companies: the original rule set tight deadlines from formation for domestic entities, but FinCEN removed those and made the change permanent on August 14, 2026, so that guidance is now obsolete for a South Dakota LLC or corporation. Foreign-registered entities have their own timelines. We apply the current South Dakota rule, not the stale deadlines still circulating online.
What happens if a foreign entity fails to file BOI?
For entities still required to report, foreign-formed ones, failing to file or filing false information can bring civil and criminal penalties under the Corporate Transparency Act. It is not a filing to ignore if it applies to you. We make sure any South Dakota-registered entity that still must report does so correctly and on time.
Can File.Business tell me if I have to file?
Yes. We assess each of your entities, where it was formed and where it is registered, against the current federal rule and any South Dakota state law, and file the BOI report only where it is actually required, so you neither miss a real obligation nor file one that no longer exists.
