Key Considerations
On the documents side, two South Dakota state-level filings matter for a secured small-business loan. The UCC-1 financing statement perfects the lender's collateral interest: $25. On the borrower's side, a minority-owned or women-owned business enterprise certification opens state procurement access: South Dakota Department of Transportation. Both filings sit outside the SBA channel; both are managed at the state level.
Interest-rate exposure on a South Dakota business loan is bounded by the state usury rule. No maximum. If the borrower defaults, 57A-9-601 South Dakota lenders typically include these remedies as enumerated rights in the loan agreement so the contractual record matches what state law would permit in any event.

Relevant Documents
Documents commonly executed at a South Dakota small-business loan closing: the SBA application form keyed to the program (Form 1919 for 7(a); Form 1244 for 504), the lender's promissory note, the security agreement, the UCC-1, and the personal-guaranty addendum.

Loan Agreement
This is the primary document that outlines the terms of the loan, including the loan amount, interest rate, repayment schedule, and default provisions. It establishes the legal relationship between you as the borrower and the lender.
Personal Guarantee
For many small business loans, lenders require the business owner to personally guarantee the loan. This document makes you personally liable for repaying the debt if your business cannot.
Promissory Note
This document is your written promise to repay the loan according to specific terms. It's often simpler than the full loan agreement but creates a legally binding obligation to repay the borrowed funds.
Security Agreement
If you're offering collateral for the loan, this document identifies the assets being pledged as security and gives the lender rights to those assets if you default on the loan.
Relevant Laws
South Dakota Codified Laws § 54-4-44
This law establishes the maximum interest rates for loans in South Dakota. In 2016, South Dakota voters approved Initiated Measure 21, which capped interest rates at 36% for most loans. Small business owners should be aware of this cap when reviewing loan terms to ensure they're not being charged usurious rates.
South Dakota Uniform Commercial Code (UCC) - Article 9
This governs secured transactions in South Dakota, including business loans where collateral is pledged. Small business owners should understand that lenders may file a UCC-1 financing statement to perfect their security interest in business assets used as collateral, which gives them priority over other creditors.
South Dakota Money Lending License Requirements (SDCL § 54-4)
This law requires lenders to be properly licensed in South Dakota. Small business owners should verify that any lender they work with is properly licensed with the South Dakota Division of Banking to avoid potential predatory lending practices.
South Dakota Small Business Development Assistance Act (SDCL § 1-53)
This establishes programs to assist small businesses in obtaining financing. Small business owners should be aware of state-supported loan programs that may offer more favorable terms than traditional commercial loans.
South Dakota Consumer Protection Act (SDCL § 37-24)
While primarily focused on consumer protection, this law also provides some protections for small businesses against deceptive practices. Business owners should know they have recourse if a lender engages in deceptive or fraudulent lending practices.
