Employee Obligations (Which Returns YOU Must File)

If you physically work in South Carolina, file a nonresident South Carolina return (tax rate: 1.99% on income up to $30,000; 5.21% on income over $30,000 (H.4216, effective tax year 2026, signed April 15, 2026). Replaces the prior three-bracket system with 6.0% top rate. Automatic trigger reductions toward zero begin in 2027 if revenue grows ≥5%.). Then file your New Mexico return and claim the RPD-41346 credit so you don't get taxed twice on the same income.
