Nanny Taxes 2017If a taxpayer pays above a certain amount to a person that works in their home, they will owe the so-called “Nanny Tax.” For 2017, the domestic employee coverage threshold, or the amount at which the “Nanny Tax” will kick in, is $2,000, which is the same as the 2016 threshold. If you pay the employee less than $2,000 in cash wages in 2016, none of the wages you pay the employee are Social Security and Medicare wages, and neither you nor your employee will owe Social Security or Medicare tax.
