Good afternoon AK,
This is on the website of RDW:
Suspend If you decide not to use your car for a longer period of time, you can suspend it for 1, 2 or 3 years. During the suspension, your car may not be parked or driven on public roads. You do not have to pay motor vehicle tax during that period. Your car does not have to be insured and MOT approved. You can extend the suspension if you do not want to use your car for a longer period of time. And of course you can also stop the suspension with us.

You can do everything via the website as long as you have a digid. Do not know if you can keep your digid as long as you are in the USA.
Greetz,
