here is code in create view:

    <div class="form-group">
        <div class="checkbox">
            <label>
                <input asp-for="IsPaid" id="ispaid" /> @Html.DisplayNameFor(model => model.IsPaid)
            </label>
        </div>

    $(document).ready(function () {
        $("#crsfees").hide();
        $(document).on('change', '#IsPaid', function (e) {
            var selected = $(this).val();
            if (selected == false) {
                $("#crsfees").val()=0.00;
            }
       });
    });
</script>

You should use the checked property:

<script>
    $(document).ready(function () {
        $("#crsfees").hide();
        $(document).on('change', '#IsPaid', function (e) {
            var selected = this.checked;
            if (selected == false) {
                $("#crsfees").val("0.00");
            }
       });
    });
</script>

To check whether checkbox is checked, use $('#Whatever_ID').is(':checked')
