CARF, DAC8, tax reporting: What do the new rules mean for Bittr? We just published a post that breaks down what the new regulation framework means and how it affects us. TLDR: 🇪🇺 EU: data collection started on January 1st, 2026, but the first reporting/exchange is expected from 2027. 🇨🇭 Switzerland: CARF is expected at the earliest from 2027. 🐷💰 For Bittr in 2026: no automatic tax reporting, and the KYC-light model (up to 999 CHF/€ per 30 days) stays.
