HOWTO Tax rule workflow
Tax rules are stored in AtomiaBilling..tax_rule. To list all tax rules, you need to run below query in database:
SELECT * from AtomiaBilling..tax_rule
ORDER BY fk_tax_profile_id, priority
Tax rules work in a way that system, when applying a tax to invoice, try to match all rules starting from one with the lowest priority, and then it applies one that is first matched.
It matches customer country code, customer country tag (NULL means that it's not relevant), a presence of VAT number, a validity of VAT number.
