Methodology

Sources

For each of the 12 tools we read the vendor's official integration directory and its per-integration pages. Where pages are rendered with JavaScript, we used the vendor's sitemap or the JSON data the page loads. We don't use third-party review sites for coverage. Every cell stores a source URL; you can download the full CSV or JSON.

Levels

• Auto-sync: the vendor documents an API key, OAuth or public-address/wallet sync.
• CSV only: the vendor documents only file import (CSV/Excel). Some vendors offer a universal CSV template; we label that in the notes.
• Listed, method unverified: the vendor lists the platform but doesn't publish the import method.
• Unknown: we couldn't verify either way. We never guess.
• Not listed: the platform isn't on the vendor's official list. We only use this for vendors whose list looks comprehensive (Koinly, CoinLedger, Summ, CoinTracker, Blockpit, Divly, rotki), and never for DeFi protocols, which are often covered through chain sync without being listed. For Awaken, Kryptos, CoinTracking, TokenTax, ZenLedger, missing platforms are Unknown.

Platform names are matched to our canonical list of 203 platforms using normalized names and aliases. A few cells were corrected by hand from the vendor's own page; those are flagged in the data.

Ranking

Tools are ranked by the number of your selected platforms they import (auto-sync or CSV), then by auto-sync count, then by country support (local forms > supported > generic report > unknown). Affiliate relationships never affect ranking.

Countries, forms & pricing

For the US (Form 8949, Schedule D, 1099-DA reconciliation), UK, Canada, Australia and Germany, we record whether the vendor documents named local forms (“Local forms”), supports the country without naming forms (“Supported”), or offers only a generic gains report (“Generic report”). Each claim links to its source on the tool page. Pricing is the official list price per tax year at check time.

Dataset

12 tools × 203 platforms = 2,436 cells: 930 auto-sync, 212 CSV only, 301 not listed, 993 unknown (40.8%).

Known limits: some vendors (CoinTracking, TokenTax, Awaken) list many integrations without a method; ZenLedger's public list is partial; integration lists change often. If you spot an error, tell us via the newsletter reply address.
