due to COVID-19, the german government decided to temporarily reduce the tax rate from 19% to 16% from July to December.
I thought this could be handled by changing the value in
/settings/tax_rates, but as far as I can see, this seems to be only valid for newly created invoices, but not for the recurring invoices.
Is there any way to change the tax value globally to the temporary new value, without having to mass modify this in the database?
If not, where do I have to change values via sql to make sure I catch them all?
