My wife and I recently hired a full-time nanny to watch our infant daughter. She works 42.5 hours per week. We're discussing what we should do when COVID finally wanes and we feel more comfortable going out for date night.
We could ask our nanny if she'd like to earn a few extra bucks. However, since we're already over 40 hours for the week, we'd have to pay her time and a half. Therefore, it makes economic sense to have some teenager or the like on retainer.
I imagine that we wouldn't have to withhold taxes for an infrequent babysitter the way we do for our full-time nanny. However, what is the exact legal requirement? Is there an annual dollar amount after which we'd have to start withholding?
For context, we live in Virginia, USA.
