Documented session methodology
This document was prepared by TaxBet (taxbet.io) using TaxBet's documented session methodology, informed by the cited authorities and configured assumptions (Chief Counsel Advice AM 2008-011; Notice 2015-21, a proposed safe harbor; Shollenberger v. Commissioner; Park v. Commissioner). Transaction data is sourced directly from supported gambling platform exports. The 90% loss deduction limitation (tax years beginning 2026) has been applied where applicable. Client filing-software entry notes are included in the client report. This workpaper is provided for tax preparation purposes. The CPA or EA of record is responsible for verifying figures and determining filing treatment. Not tax advice.
Methodology. Under IRS guidance and case law (Chief Counsel Advice AM 2008-011; Notice 2015-21, a proposed safe harbor; Shollenberger v. Commissioner; Park v. Commissioner), a casual gambler's income may be measured by session rather than by adding up Forms W-2G. TaxBet documents that computation for you and your tax professional to review. Configured default: one session per establishment per calendar day, with the per-game-type grain available where the preparer elects it. Sportsbook rows are set aside — disclosed, never included in casino session math — pending the sports session ruling. W-2G figures shown are estimates of information-return exposure unless actual forms are supplied; supplied forms are the authoritative reconciliation target. Full assumptions and citations below.
