Does a household employer have to pay social security and Medicare for all household employees if only one employee makes more than $1,300 in the year?
No. The employer only has to pay social security and Medicare tax for the employee(s) who receive $1,300 or more in wages for the year. If the amount paid to any employee in a calendar year is less than $1,300, no social security or Medicare tax is owed for that employee. If social security and Medicare tax must be paid, the employee’s portion of the social security and Medicare tax should be withheld also, unless the employer chooses to pay both the employer’s share and the employee’s share.
