Put a tax report button where your users already are.
Give your traders a one-tap path from messy on-chain history to a compliant, filing-ready tax report — without building or maintaining any of it yourself. One server-to-server call. Read-only by design.
Tax reporting just became your users' problem to you.
From 2025, centralised exchanges must report disposals to tax authorities on new digital-asset forms — but the cost basis behind those numbers is usually missing or wrong, especially once funds move between platforms. Your users feel the gap first, and they come to you.
A credible tax product behind a single button.
Coinfig is built for the messy middle of crypto tax — imports, transfer matching, reconciliation, completeness checks and report generation. You bring the users and the trust; we keep the engine running.
Zero product work
We build and maintain the integration, the reconciliation engine and the reports. No roadmap line, no on-call, no format-chasing when an asset standard changes.
Read-only by design
Connections exist to import and reconcile history — not to trade or hold funds. Keys are scoped, passed server-to-server, and never exposed in the browser.
New revenue & retention
Earn a share on every report your users buy, and give them a reason to come back at the one moment they're most likely to churn — tax season.
Fewer tax-season support tickets
Instead of agents fielding "where's my statement / why is my gain wrong" threads every April, users self-serve a defensible report with completeness checks that surface gaps before anyone files.
Four steps. No SDK, no client-side keys.
A user opts in inside your product, your backend mints a read-only key and makes one call, and Coinfig provisions the account and hands the user back. Everything sensitive stays server-side.
User opts in
They tap “Get your tax report” somewhere natural in your app. No new account, no leaving your brand.
In your productYou mint a read-only key
Your backend generates a per-user, read-only API key scoped to transaction history.
Your backendOne call to Coinfig
A single server-to-server POST with the user and the key. We provision, import and reconcile.
Server to serverUser lands on their report
We return a passwordless sign-in link; you redirect. The report is ready to file or share.
Back to the userStart lightweight. Go deeper when it pays.
Pick the relationship that fits how close you are to the user. The numbers below are illustrative ranges to set expectations — final commercial terms are agreed privately, per partner.
Introduce users who need tax help
Point users to Coinfig with a co-branded link and a discount code. Lightest lift — no integration required.
Offer reporting as your own service
Wrap Coinfig into your client offering and manage the relationship. Best for advisors, firms and managed platforms.
Embed the button in your product
The full server-to-server integration with a native “Get your tax report” button. Best for exchanges, wallets and neobanks at scale.
What could a tax button be worth to you?
Drag the sliders for a rough, illustrative sense of annual reports and partner revenue. Real figures depend on your audience, market and agreed terms — this is a conversation starter, not a quote.
See exactly what your users and engineers would get.
We built SixpenceX, a fully worked example exchange, so you can validate the whole thing before you commit a single sprint. Walk the user flow, read the real integration guide, and try a sandbox request — all openly, before we hand you your own private docs and token.
If your users hold crypto, they'll need this in April.
We work best with platforms that already own the user relationship and want a credible tax answer without becoming a tax company.
Crypto exchanges
Embed the button natively and turn tax season into a retention and revenue moment instead of a ticket surge.

Add a compliance feature your users expect from a modern money app, with no card-rail or custody changes.

Give crypto clients a defensible report and supporting schedules, then review instead of rebuild.

Tell us where the partnership could fit.
Three short steps. We only need enough to route the conversation and decide what to share next — your private docs and a sandbox token if there's a clear fit.
