You have to return JSON error object yourself after setting the StatusCode, like so ...

if (BadRequest)
{
    Dictionary error = new Dictionary();
    error.Add("ErrorCode", -1);
    error.Add("ErrorMessage", "Something really bad happened");
    return Json(error);
}

Another way is to have a JsonErrorModel and populate it

public class JsonErrorModel
{
    public int ErrorCode { get; set;}

    public string ErrorMessage { get; set; }
}

public ActionResult SomeMethod()
{

    if (BadRequest)
    {
        var error = new JsonErrorModel
        {
            ErrorCode = -1,
            ErrorMessage = "Something really bad happened"
        };

        return Json(error);
    }

   //Return valid response
}
