Crypto taxes: how it works
Many tax systems treat crypto as property, so selling, swapping or spending it can trigger a capital gain or loss.
Each disposal needs a cost basis, which is why good records are essential.
A second example with larger figures
Scaling the inputs up shows how the result moves. Percentages stay the same, so the tax grows in proportion to the amount it is applied to.
| Purchase price | 26,250.00 |

| Costs and fees | 262.50 |
| Tax rate (%) | 15% |

| Tax | 2,323.12 |
| Net amount | 39,414.38 |
