How to Save Money on Your South Dakota LLC

File in your home state

Forming in South Dakota while living elsewhere means paying fees in both states plus foreign qualification. If you operate in South Dakota, file there locally.

Get your EIN directly from the IRS

The IRS charges $0. Any service charging $100+ for "expedited EIN" is upcharging — unless you specifically need international expediting.

Use a commercial registered agent

~$100/yr is cheaper than a PO Box + mail forwarding + missing service of process. Your home address also stays off public records.

Skip third-party LLC kits

Physical LLC binders and seal kits are a relic. Operating agreements are digital. Save the $50-$200.

Bundle formation services

FormifyAI bundles state filing + RA + operating agreement + EIN + BOI filing for one monthly fee — often cheaper than buying each separately.

Ongoing Annual Costs (Year 2+)

State annual report$50/yr

Registered agent~$100/yr
