Current FICA taxes (SS and Medicare) are 15.3%. Typically, the employee (your nanny) pays half and you pay half. Your half is ON TOP OF what you pay her. Her half is deducted from her pay check (so, 6.2% for SS, and 1.45% for Medicare).
There is an option for you to pay it all, but most people do not do this. There is no option for her to pay it all. You must pay at least half.
You will also need to pay unemployment insurance (state and federal). You can pay your federal UI and your portion of the FICA taxes on your personal return before April 15. You will need to set up an account in your state for state unemployment insurance.
I would only add that the way the nanny "pays" for her share of SS is via deductions that you make.
I second the suggestion for a payroll company. We have used Homework Solutions for almost 3 years. When we changed nannies she wanted to know her take home and they provided a detailed breakdown with just a phone call.
