Pass-through entities (i.e., S corps, partnerships, limited liability companies) must withhold income taxes at the highest marginal rate from cash distributions made to nonresident individuals. Withholding isn’t required if nonresidents’ share of taxes is less than $1,000 or they elect to have their entities pay and report their taxes. Withholding also isn’t required if individuals file certifications of residency with their entities on forms approved by the Tax Commission. Amounts withheld must be remitted by Jan. 31 of the following year. (Reg. 35.01.01.877)
