paying a nanny's tax and national insurance

[alderpants]

both myself and another family use a nanny for the same amount of hours term time, but then in the school holidays the other family uses her more (4 whole days) and me considerably less (1 day).
how do we both benefit from the tax free allowance a nanny is allowed and the following 10% taxable amount?
any one have experience of this? thanks!!

why don't you just add up the number of days you have her a year and the number of days they have her a year and then divide the benefits over the 12 months?
