File your crypto tax
with confidence.

Coinfig uses FIFO, first in first out. The units you acquired earliest are treated as the first ones sold.

The full working is shown behind every disposal so you can trace which acquisitions were matched to each sale.

Ireland has a four-week rule. A sale is first matched with coins of the same kind you bought in the four weeks before it, and only then with older coins under FIFO. If you sell at a loss and buy the same coin back within four weeks, that loss can only be used against a gain when you later sell the coins you bought back. Coinfig applies both parts.

The working for each match is shown in your report so you can check it.

Most people who buy and hold are taxed on capital gains, and that is where Coinfig starts. If your crypto activity is a trade, your gains may instead be taxed as trading income.

You choose in your Preferences, and your report states the choice. If you are not sure, check with a tax adviser.

Crypto received as income, for example from staking rewards, mining or payment for work, can be taxable when you receive it, separately from any later gain on disposal.

Coinfig records these as income events, kept apart from your capital gains. Because the treatment depends on the facts, confirm your situation with a tax adviser.

Figures and reports are shown in euro. Every transaction is valued in euro at the rate on the day it happened, and any price we had to estimate is marked so you can check it.

Yes. When you connect an exchange through its API, Coinfig uses read-only access to import your transaction history. It cannot place trades or move funds.

If you prefer not to share an API key, you can also import your history by CSV from most exchanges.

No. Coinfig provides calculations and reports based on the data you import and the settings you choose. It does not provide personalised tax advice, and it does not imply any endorsement or approval by the Irish tax authority.

For complex situations, such as business trading, mining or unusual transactions, consult a qualified tax adviser. You remain responsible for what you file.
