WagerBooks started from our work as a backend accounting partner, and grew into a specialist back office for gambling tax documentation.
WagerBooks started from our work as a backend accounting partner.
We first built our expertise in crypto accounting, where we worked behind accounting firms and supported them with complex, process-driven work. During that journey, one of our long-standing clients asked us to help with a session gambling report.
We started that work to support the client. But the work was deep and complex. It required us to understand how gambling platforms structure their data, how the IRS session method actually works, how W-2Gs need to reconcile against full transaction histories, and how clean records are prepared for a CPA to review.
That experience opened a new direction for us.
Today, WagerBooks is focused on backend data and reconciliation support for CPAs, tax attorneys, and law firms whose clients have gambling activity. We pull raw transaction data from gambling platforms, apply session-level logic consistent with IRS documentation standards, reconcile every W-2G back into the session log, and deliver reports your CPA can work with.
We are not a tax firm, and we do not provide tax advice. We work as a backend data and reconciliation team, helping gamblers and their CPAs keep the records clean, complete, and audit-ready.
Gambling tax reporting has its own language, process, and complexity. Platform data, session logs, W-2G reconciliation, crypto wagers, multi-state activity, and IRS documentation standards all need to connect properly.
Our goal is to become a focused backend data and reconciliation team for serious gamblers and the CPAs who serve them. We want to keep the process simple for the client and the firm, while handling the complexity carefully in the background. Click any card below to read more.
This is the hardest part of the job. Every gambling platform structures its data differently, different export formats, different login and identity-verification hurdles, and data that arrives incomplete, mixed with bonus amounts, or split across inconsistent fields. Pulling clean, complete data across dozens of platforms takes real specialist skill.
See a real case study →We group every wager into IRS-recognized gambling sessions, netting wins and losses the way the session method actually requires, not just totaling W-2Gs.
Every official W-2G form is matched and reconciled against the full platform transaction history, so nothing is reported twice and nothing is missed.
Reports are delivered in a clean, CPA-ready format structured around widely followed gambling documentation standards, ready for your firm to review and file.
Sportsbooks, online casinos, DFS apps, and poker platforms, we support data extraction and reconciliation across a wide and growing list of gambling operators.
Crypto-based gambling activity is documented alongside on-chain transaction details, so the gambling outcome and the related capital-gains treatment can both be addressed.
We reconstruct historical, back-year session reports from whatever platform data can still be retrieved, ideal for IRS notices and audit prep.
We work as a white-glove, client-facing partner to CPA and accounting firms, handling the platform and client communication so your team doesn’t have to.
Your client has a gambling problem, not the kind you are thinking. We handle the data so you can handle the tax.
When gambling activity becomes part of a legal matter, we give you clean, structured records to work from.
Casinos, gambling coaches, podcasters, content creators, financial advisors, if your audience gambles, they will eventually need clean tax records. You send them to us, we handle the documentation, and they come back to you with one less problem. Simple referral arrangements available for qualifying partners.
