Maybe you don't know what Real Time Information is, but if you employ a nanny it is going to affect you from 6th April 2013.
One of the big changes is that you (or your payroll provider) must make a report to HMRC on or before the day you make any payment to your nanny (except reimbursement of expenses), including a calculation of tax and NI due.
But HMRC have announced today that for 6 months only, if you employ fewer than 50 staff you don't have to make that report until the end of the tax month (which is always on the 5th of the month).
Is that going to help? Not really, unless you pay your nanny a net wage (which is not a good idea anyway) depending on how many hours she works up to the day of payment.
