Cryptocurrency taxation question: are staking rewards basically tax-free in Finland, if the crypto in question doesn’t go up in value by the time you sell the rewards?

I would have thought that the cost basis of daily staking rewards would be zero, and the tax burden calculation would go something like this (reward rates made up, ETH price is assumed to remain fixed at 1000 Euros/ETH throughout the year for simplicity):

* Buy 1000 ETH for 1000 Euros/ETH
* Stake them
* Receive 1 ETH daily, for 365 days, do not compound
* At the end of year, you have 1365 ETH
* Sell all of them for 1000 euros/ETH
* Profit from initial 1000 ETH: 0 Euros
* Profit from rewarded 365 ETH: 365000 Euros (given that, for rewards, your acquisition cost was zero Euros/ETH)
* Pay taxes on 365000 Euros profit

But multiple soures, including Vero (quote at the bottom of this post), seem to imply it would go something like this (only the bolded part is different):

* Buy 1000 ETH for 1000 Euros/ETH
* Stake them
* Receive 1 ETH daily, for 365 days, do not compound
* At the end of year, you have 1365 ETH
* Sell all of them for 1000 euros/ETH
* Profit from initial 1000 ETH: 0 Euros
* **Profit from rewarded 365 ETH: 0 Euros (given that, for rewards, your acquisition cost was market value of the crypto by the time you got a hold of the rewards, which we assume was 1000 Euros/ETH all year)**
* **Pay taxes on 0 Euros profit, even though you received 365 ETH from thin air**

This doesn’t sound right to me, but I don’t know how else to interpret Vero’s instructions. Looking for input from people that has past experience filing staking income. I will ask Vero too.

[Section from Vero](https://www.vero.fi/en/detailed-guidance/guidance/48411/taxation-of-virtual-currencies3/), relevant part bolded:

> The accumulation of new virtual currencies can also be based on the blocking of existing virtual currencies for a time, in order to protect the virtual currency in question. The reward for this may be an increase of 5% per annum (or other comparable percentage) on top of a miner’s existing virtual-currency balance, paid on a daily basis (the proof-of-stake protocol). From the perspective of taxation, this is a direct gain on a previously held asset, and consequently, it is regarded as a capital gain.
>
> The point in time when income is realized for purposes of taxation is when the miner gains possession of the new units of virtual currency. **The income is valued at the market value of the virtual currency at that time. The amount of income received is also the gross acquisition cost for the newly acquired virtual currency.** The acquisition cost of the miner’s old virtual currency remains unchanged. The same principle can also be applied to other situations where a taxpayer’s income is based solely on a gain on previously owned virtual currency.

Edit:

[Another, non-Vero source](https://divly.com/en/guides/crypto-taxes-finland):
> Staking
>
> Staking, an alternative to mining, contributes to your capital income and is seen as a capital gain. This classification is different from mining because staking is a reward for owning crypto assets. **You must report the value of your staking income in euros at the time you receive the tokens. This value is also considered the acquisition cost.**
