How my payment plugin can add additional row of tax per bill in the cart? And recalculate 'total'.
This tax should be applyed only when is selected my payment plugin. Thanks a lot for someone who could answer this question.

You can apply tax rules inside the config of your payment plugin.

Inside .xml file? What is the right format? Will they automatically apear in the cart?

no

virtuemart backend -> shop -> paymentmethods

choose your payment method and on the second tab are settings for tax

I got it already. But how can i add more than one tax rule? My client wants alternate tax an duty to apear in the cart. So as i see there should be to tax per bill rules applyed. I've tried to copy the field tax_id in the config(xml) and past it renamed as tax_id2. So i renamed also all identifiers related(in language ini) etc. And added additional row to db on plugin initialization. But only thing that happened is weird dissapearance of tax rules in plugin config tab. Remained only 'no rules' and 'default rules'.Everything else working fine.

You can have multiple rules ... one with 10% and another with 20%.

On Payment configuration choose "default rules".

In this case both rules are applied to your payment fee.
