For a secondary occupation that falls under the vAT exemption rule, I have a question about how you treat costs that are mainly for private use. I am thinking of internet and telephone costs, but also fuel costs and a percentage of the mortgage. But above all, is it now required to have these costs flow through Peppol? Or are you also legally okay if you have these costs invoiced to your private account as before and claim a percentage? And with that, the question of how this should/can be done in practice via the accounting platform.
