Common gotchas

BCB-aligned exchange recommended (Mercado Bitcoin, Foxbit, Bitybank, Coinext); Binance Brazil in BCB authorization process
CPF + photo ID + address proof required for all Brazilian CEXes; PIX-funding free + instant
R$35,000/month exemption applies ONLY to regulated-venue disposals; offshore disposals taxed from R$1 under Law 14.754/2023
Law 14.754/2023 (offshore crypto/foreign-asset reform): 17.5-22.5% progressive IR on offshore gains + yield; effective Jan 2024
IR-PF Bens e Direitos: declare crypto holdings >R$5,000 (per asset class) annually by April 30
Swap = TWO IR events (disposal of source + acquisition of target); both BRL FMV at execution

Step-by-step

Recognize swap = taxable disposal. Swapping UNI for any other crypto in Brazil is a 15% IR disposal (regulated venue, if monthly >R$35k) or 17.5-22.5% progressive (offshore venue, Law 14.754/2023). Acquisition basis of received asset = BRL FMV at swap execution.
Choose Brazilian CEX or offshore route. Brazilian CEX (Mercado Bitcoin, Foxbit, Bitybank, Coinext, Binance Brazil): 15% IR with R$35k/month exemption. Offshore venue or self-custody DEX: 17.5-22.5% progressive IR on ALL gains (no monthly exemption).
Verify R$35,000/month threshold. If your TOTAL monthly disposals across all crypto and all venues <R$35,000, regulated-venue swaps are tax-EXEMPT. This is a key Brazilian advantage — track cumulative monthly volume.
Execute swap on chosen venue. CEX swap auto-issues BRL FMV confirmation. DEX requires connecting wallet + setting slippage (0.5-1%).
Report on IR-PF + IN 1888 / 2161. Each swap = two IR events (disposal + acquisition). Regulated venue: Bens e Direitos. Offshore: full progressive IR per Law 14.754. IN 2161 monthly DeFi report; IN 1888 aggregate.

Tax summary

Swapping UNI for any other crypto IS a taxable disposal at BRL FMV. 15% IR on monthly gain >R$35k (regulated venue); 17.5-22.5% progressive (offshore, Law 14.754/2023). Each swap = two IR events (disposal + acquisition).
