Are multiple rates of the same tax supported? – RightPress Support

Yes. Some countries use variable VAT (or other tax) rates for different goods and services and WooCommerce PDF Invoice comes with a support for this (with some limitations).

If you use different tax rates for different products and these products happen to end up in a single order, WooCommerce PDF Invoice will do the following:

Determine tax rate and calculate tax for each line item individually (by default WooCommerce only provides line subtotal and line tax).
Switch table layout to a different one to display net amount, tax rate and calculated tax for each line item.
Ignore "Display tax rows" setting completely - display all subtotals inclusive of tax and hide tax rows on the totals block (except of shipping and shipping tax).

Limitations:

Using different tax rates for different products and using multiple tax rates (either compound or not) for one product together is not supported.
If you set prices inclusive of tax, in some rare cases tax may be calculated with an error of one cent due to rounding.
Since a lot of columns need to be displayed, in rare cases column names and values may not fit nicely into table cells. Try using abbreviations and hiding currency symbol.
