Detailed Review
CryptoDeclare is a one-person Swiss service; the Impressum names a sole trader in Nyon, canton Vaud. You upload supported exports, the service calculates and you download a report for your cantonal declaration.
The site says transaction files stay in your browser and are not uploaded to its servers.
Swiss reference rates
Fiat conversions use the official monthly CHF rates from ESTV and BAZG, and the method is FIFO, which the site says is common among Swiss fiduciaires.
Completeness checks
The tool flags missing acquisition history, unmatched FIFO disposals and incomplete imports before export, so gaps show up before you file.
No exchange connection
There is no API connection to exchanges. You import supported CSV or Excel exports and check the coverage list for your platform.
Limitations to Consider
It is a single-person service with no API connections, and coverage depends on selected exchange export formats. The Impressum says reports do not constitute official tax filings and should be verified with a fiduciary. The site is for Swiss tax only. For a team-backed multi-country option, see Blockpit.
Who Should Use CryptoDeclare
Swiss residents with exports from the common exchanges who want a transparent FIFO annex and prefer that files stay local.
