Host: What do I need to do in terms of taxes? Jaclyn Gobuluk: When hiring a nanny you want to be sure to calculate all the taxes for the nanny. With that, you want to contact a local tax expert and preferably someone who has dealt with nanny taxes in the past. In order to find the tax expert you would want to research maybe by going through the yellow pages or do an internet based search and search under Nanny Tax Specialists.
