Paxum is a Canadian payment service provider founded in 2007 that specializes in the adult industry. Platforms like OnlyFans, ManyVids and many cam sites use Paxum for payouts because PayPal, Twint, Stripe and traditional banks usually block adult content.
In Switzerland, Paxum payouts are fully relevant for tax purposes. Recommendation: pay out Paxum wallet regularly to a Swiss bank account, archive payout receipts - the tax administration may request these.
