Under FICA, how are Social Security and Medicare taxes generally allocated between employer and employee?

解析

FICA splits the Social Security and Medicare tax down the middle: 26 U.S.C. §3101 imposes the employee's half, withheld from wages, and §3111 imposes a matching employer half. (a) and (d) are the two ways of believing one side carries it all - (a) is what a worker paid on a 1099 actually experiences, because a misclassified worker ends up paying both halves as self-employment tax. (c) inverts the rule: the self-employed pay both halves under SECA, 26 U.S.C. §1401, but employees and employers pay FICA too. This split is exactly what a contractor avoids by misclassifying a crew, and exactly what EDD assesses back.
