I am a tax attorney. Most people do not handle nannies in the technically correct manner, so comparing your situation to others is not likely to give you a correct idea of how to handle it. It is different when you open your own home to children, in which case you are truly an independent contractor and the parents have no responsibility to withhold taxes or send you a W-2. If the parents want to get a child care credit on their return, they will be required to report the funds they paid to you on their tax return, along with your name, social security number or employer identification number. A nanny who works in the parent's home, however, is considered household help of the parent, and the parent is responsible for reporting wages paid if the nanny makes more than a certain amount, which I believe is $1,400 for 2007 and 2008 (you can find that on the IRS web site). If the nanny makes more than $1,400 from one household, that household is responsible for payment of the SOCIAL SECURITY TAXES of the nanny and reporting the wages to the IRS on a W-2. As the other person posted, the parent will have responsibility to pay state unemployment taxes if one quarter's payments to the nanny exceed $1,000. The parent can choose to withhold the employee's share of the social security (7.65% of gross pay) from the employee's pay; if the parent does not withhold it, then the parent still has to pay it to the IRS. Additionally, the parent must pay the employer's share of social security (7.65%-matches the employee's share). The parent IS NOT required to withhold federal income taxes, but the nanny can request that those taxes be withheld. If the nanny requests that income tax be withheld, then obviously she would not collect the entire $15 per hour (and yes that is a very high salary). I normally negotiate all these kinds of issues before employment starts so there is no misunderstanding about the pay. The fact that a nanny gets a job through an agency rarely has any effect on the parties' liability for employment taxes; generally the nanny agency just performs a referral service and the salary, taxes, etc. are up to the parent and the Nanny. I suggest that your friend discuss the issue with the parents and the parents should discuss it with their accountant. good luck.
