Multi-book normalization
Parses DraftKings, FanDuel, BetMGM, Caesars, and Fanatics exports—each with different column names and date formats—into one unified ledger.
IRS session method (AM2008-011)
Transactions are grouped per day and per book into sessions, netting wins and losses the way the IRS and tax court require—not per-wager netting.
State-specific rules
Applies diverging state rules for NJ, NY, PA, CT, and NC—including the OBBBA 90% federal cap and no-deduction states—producing separate federal and state figures.
Audit-defense workpaper
Generates a signed XLSX ledger and a PDF cover sheet citing AM2008-011 with reconciled session totals, ready for the client file or an IRS response.
