What this income means in South Dakota
From $50,000 to $150,000, South Dakota workers keep every dollar that a state tax would take elsewhere. A single filer earning $100,000 takes home $79,180, or $6,598 a month, and a married couple filing jointly on $100,000 keeps $84,710. Because there is no state tax, a traditional 401(k) saves only the 22% federal rate here, which makes a Roth 401(k) worth considering if you might retire in a state with an income tax.
