Just announced, the new South Dakota Minimum Wage for 2019 is increasing 25 cents per hour. The new rate of $9.10 per hour is up from $8.85 in 2018. The new rate becomes effective on January 1, 2019.
South Dakota's minimum wage is adjusted on an annual basis, increasing at the same rate as the cost of living as measured in the Consumer Price Index published by the United States Department of Labor. The amount of the increase will be rounded to the nearest five cents. The state minimum wage cannot decrease.
There is no state statute that requires a poster to be displayed regarding minimum wage. However, South Dakota's State Department of Labor provides one as a courtesy to employers, and many employers do post this in their workplace at a location where employees can see it and other postings are made.
