Taxify bonuses constitute remuneration for driver loyalty (your readiness to accept ride requests via Bolt platform). The basis for bonus payment is an invoice issued by the driver. This loyalty service is subject to 0% VAT in Finland (reverse charge applied in Estonia). When you receive a bonus, Bolt will automatically issue an invoice in your name and on your behalf.
It is your duty to report this via the EC Sales List (Yhteenvetoilmoitus). Note that Bolt has a separate billing entity named Billify OÜ, hence the VAT number of Billify OÜ - EE102090374 - must be indicated for these purposes. You will not have to pay any VAT on the bonus payment, it is, however, part of your business income.
