How to pass complex ViewModel to service level in ASP.NET MVC?

Question

Let's say I have a RegisterModel for registering a user, and some UserService that implement IUserService

public interface IUserService
{
   User CreateUser(User newUser);
}


[HttpPost]
public ActionResult Register(RegisterModel model)
{
            if (ModelState.IsValid)
            {

                // ... logic for newuser

                User user = _userService.CreateUser(newuser);

               _authenticationService.SetAuthenticatedUser(user);

                return RedirectToRoute("Homepage");
            }

            return View(model);
        }

Given that RegisterModel can be very complex, where the logic needs to go to map RegisterModel to a User object
