South Dakota w-9 request for taxpayer identification number
Every general contractor, property manager and insurance carrier that pays you needs a W-9 on file before they cut the first check. Keeping a current one ready removes the most common reason a first payment sits in accounts payable.
What goes on the South Dakota version
- Legal business name and any DBA line
- Federal tax classification and exempt payee code where applicable
- EIN or SSN and business mailing address
- Signature and date certification block
South Dakota jobs get the national baseline packet. Every field a building department needs is covered; state-specific attachments are being added market by market.
Mistakes that get it kicked back
- Using the DBA on the legal-name line, which triggers a TIN mismatch notice
- Checking sole proprietor when the entity is actually an LLC taxed as an S-corp
- Sending an unsigned copy, which payers will reject
