kointax vs. manual declaration in Renta Web
You technically can calculate gains manually and enter them in Renta Web — feasible for users with few simple operations.
Why it gets complicated quickly:
- Global portfolio FIFO is error-prone to calculate manually
- DeFi users can have hundreds of swap events
- Multiple exchanges/wallets require complex consolidation
- Models 172/173 must be consistent with IRPF
kointax vs. manual:
| Feature | Manual | kointax |
|---|---|---|
| Auto global FIFO | ❌ | ✅ |
| 300+ exchange imports | ❌ | ✅ |
| Auto DeFi classification | ❌ | ✅ |
| Models 172/173 generated | ❌ | ✅ |
| 10 operations time | ~2h | ~15min |
| 500 operations time | Weeks | ~1h |
Manual is OK for: <10 operations/year, only simple buy/sell, no DeFi.
kointax needed for: Active DeFi, staking/farming/NFTs, multiple exchanges/wallets, needs Models 172/173.
