Unemployment tax

Most companies are liable for state unemployment if they have one or more employees in 20 different weeks in a calendar year or pay $1500 of payroll in a calendar quarter. You can find out if you are liable and register online with the South Dakota Department of Labor UI Division to obtain a SUTA Account Number. You should receive your number instantly after registering online, or in 10-14 days if registering by mail.

Unemployment tax rate

After registering online, you will also receive their UI rate and South Dakota Investment Fee rate. The UI rate for new employers is generally 1.2%% (except for construction which is generally 6%). New employers are also assessed an Investment Fee of 0.55%.
