If you are a household worker--for example, a cleaning person, cook, gardener, or baby sitter--and you earn $1,800 or more in cash wages during 2012 from one employer, that employer must deduct Social Security and Medicare taxes from your wages. The employer will report your earnings to Social Security after the end of the year.

If you earn less than $1,800 in 2013 from that employer, the earnings are not covered and will not be reported.

Earnings for household workers (such as baby sitters) who are under age 18 are exempt from Social Security and Medicare taxes unless household work is the young person's primary occupation.
