Every time you pay for a coffee or a dinner with your crypto card you are making a disposal (you sell crypto for euros to pay the merchant). That produces a capital gain or loss that has to go into your Spanish income tax return. At Cryptoimpuestos we automate the calculation of these micro-transactions so your report is exact without you reviewing thousands of receipts.
Yes. Activity on DeFi protocols (Uniswap, PancakeSwap) and the use of cross-chain bridges (Arbitrum, Polygon) is exactly where automated software fails most often. Our technical team analyses the on-chain trail to identify swaps, liquidity provision and farming correctly, so the tax report reflects what your portfolio actually did. (Linked article in Spanish.)
Yes, these situations can be declared as a capital loss, but the tax authority requires solid technical justification. We help affected individuals document those losses in their tax report so they can offset them against other gains, turning a bad situation into a legitimate tax saving.
In those cases the acquisition value is not what you paid (nothing), but the market value of the asset at the moment of the gift or the death, plus any inheritance or gift tax paid. At Cryptoimpuestos we adjust your report so the entry price is correct under Spanish law, which stops you overpaying when you sell.
Game assets and NFTs have their own tax treatment. Income from playing is generally treated as business income or as a capital gain, while NFT sales are taxed in the savings tax base. We classify each of these assets so your return has no weak points if it is reviewed.
Even with a small portfolio, a minimum penalty from the tax authority can exceed €300. Our Fish plan exists precisely for small investors who want to sleep at night knowing their return is right. And if you are sitting on losses, declaring them lets you save tax over the next four years once you are back in profit.
Of course. We know most traditional accountants do not work with crypto tax. The service includes coordinating with your usual adviser, explaining the criteria we applied (such as FIFO or the savings tax base) so all they have to do is carry the final figures into your return. (Linked article in Spanish.)
Our reports are not documents a machine spat out. They are designed under the supervision of our co-founders (Víctor, Rafael, Alberto and Martín) following the binding rulings of the Spanish tax directorate. If you are audited, the report serves as documentary evidence of where your funds came from and went, which makes defending your case far easier.
