Using PHP's PCRE feature you can use this regex to replace only 2nd instance of Tax:

$str = 'Add New Tax Rate,Add New Tax Rate';

$repl = preg_replace('/^.*?\bTax\b(*SKIP)(*F)|\bTax\b/', 'REPLACED', $str, 1);

//=> Add New Tax Rate,Add New REPLACED Rate

RegEx Demo

Here ^.*?\bTax\b(*SKIP)(*F) will match and skip first match of Tax.
