1. Annual Renewal Requirements
   
   

   (1)	Annual Report All active business entities registered at South Dakota must file Annual Report with the South Dakota Secretary of the State. Annual reports are due every year on the 1st day of the anniversary month of when the business was filed. Failure to file the required Annual Report, the entity will receive a notice of pending dissolution or revocation, then you have 60 days to comply.
   (2)	Registered Office and Registered Agent South Dakota law requires that every business entity must have and maintain a Registered Agent in the State of South Dakota. The registered agent must have a physical street address in South Dakota. Kaizen provides professional service to help clients maintain and renew the registered agent annually.
   (3)	Business License/Permit Renewal (extra fee required) In the situation where a South Dakota registered company holds a business licence or permit issued by the Federal or State Government because it engages in one or more regulated business, in general, such a licence or permit must be renewed each year.

2. Corporate Income Tax Filing
   
   

   (1)

   Federal Income Tax Return According to Internal Revenue Service (IRS), all business entities must file an income tax return on or before the following April 15th (Corporation) or March 15th (LLC) of the tax year, or Oct 15th (Corporation) or Sep 15th (LLC) with extension, if the company adopts the calendar year as its accounting year. However, a business entity must still pay its tax due in full no later than the original deadline for filing of its tax return (not extended deadlines). Interest and penalty will be charged for late payment of tax if an extension of time to file is granted. A LLC is also required to file a federal income tax return each year without paying any income tax because a LLC is by default a pass-through entity unless it choose to be taxed as a corporation. Should a LLC makes such as choice, then it will need to file the Federal Income Tax Return and at the same time pay federal income tax at company level.
