Something like following should work,

markup

<div class="tax">
    <input type="text" maxlength="1" />
    <input type="text" maxlength="4" />
    <input type="text" maxlength="5" />
    <input type="text" maxlength="2" />
    <input type="text" maxlength="1" />
</div>

script

$(function () {
    $('.tax input[type="text"]').keypress(function (e) {
        if (e.which == 0 || e.charCode == 0) {
            return true;
        }
        var str = String.fromCharCode(!e.charCode ? e.which : e.charCode);
        str = $(this).val() + str;

        if (str.length == $(this).prop('maxlength')) {
            var that = this;
            window.setTimeout(function(){
                $(that).next('input[type="text"]').focus();
            }, 0);
        }
    });
});
