South Dakota lesson 6 of 6
Open a bank account and file your South Dakota annual report
Once your South Dakota LLC is formed and registered for any needed sales tax license, two things keep it running: a properly separated bank account and the annual report filed every year with the Secretary of State.
Opening the account
Bring the filed Articles of Organization, your EIN confirmation letter, an operating agreement if you have adopted one, and identification for signers and significant owners. Route all business income and expenses through this account, since commingling personal and business funds undermines the liability protection an LLC is meant to provide.
Filing the annual report
South Dakota LLCs file an annual report with the Secretary of State every year, due by the first day of the anniversary month of formation. Filing online costs $50; filing on paper costs $65, following the same online-versus-paper fee split used for the original Articles of Organization. The report confirms or updates the LLC's principal address, registered agent, and registered office on file.
You can file the annual report through the Secretary of State's online business filing system, the same portal used for formation, or check whether your business is due by searching your entity on the Secretary of State's site.
A delinquent annual report carries an additional $50 penalty on top of the base filing fee.
If you miss it
An LLC that fails to file its annual report can be administratively dissolved by the Secretary of State, generally after a grace period of about two months past the due date. A dissolved LLC can typically apply for reinstatement by filing the missing reports and paying the associated fees and penalties, but it is not in good standing in the meantime, which can affect contracts, licensing and financing. File on time and keep your registered agent information current so you receive the reminder.
Key takeaways
- The annual report is due by the first day of your LLC's anniversary month every year.
- Filing online costs $50; filing on paper costs $65, and a delinquent report adds a $50 penalty.
- Missing the deadline for an extended period risks administrative dissolution, though reinstatement is generally available.
