Hi Aleksandre,

Please add the custom code below. (How to add custom code? ↗):

add_filter( 'wpcot_tip_amount', function ( $amount ) {
    return number_format( $amount, 0 );
} );

Please REPLACE the old snippet with a new one:

add_filter( 'wpcot_tip_amount', function ( $amount, $tip ) {
    $value = preg_replace( '/[^-.,%0-9]/', '', $tip['value'] );
    if ( str_contains( $value, '%' ) ) {
        $amount = ( (float) $value / 100 ) * ( WC()->cart->get_subtotal() + WC()->cart->get_subtotal_tax() );
    }
    return number_format( $amount, 0 );
}, 99, 2 );

Now, it will be calculated using the amount after tax.

We'll implement the taxable option for each tip soon. After that, you don't need to use the above snippet anymore.
