ContractTax

ContractTax is a web-based analytics and reporting platform built for Kalshi prediction market traders. It records historical prices and outcomes to help users distinguish good value from overpriced contracts and supplies tax estimates, profit-and-loss tracking, and a Sharp Score that rates trading edge.

The service supplies a range of specialized modules. Kalshi Radar scans for current market movement and explanations. A screener applies user-defined rules across available contracts and issues alerts on matches. The settlement calendar lists daily closures along with economic data flags. Trade Checker calculates fee-adjusted expected value and position sizing prior to execution. Truth Machine evaluates what each price level implied once events resolve. Momentum Machine indicates whether to chase or fade moves based on recorded price paths. Strategy Lab runs backtests of rules against actual settled outcomes. The Sweat Board displays live open positions with simulated odds for the current night. Watchlist plus Alerts sends threshold-based emails. Trade Report analyzes complete trade history for taxes, performance leaks, and comeback planning. Bankroll Guardian tracks and monitors monthly results automatically. Prediction Journal records probability estimates and measures calibration over time. Market Field Guides outline edges and red flags for ten market families. Additional components include Crypto Pulse, a Netflix Top 10 Tracker, a simulator, and assorted calculators accessible from the Tools page.

ContractTax presents itself as a full toolkit supporting the sequence of finding, vetting, holding, reviewing, and learning from trades. It generates IRS-ready tax forms derived from trade history and supplies illustrative federal-rate estimates for planning purposes while explicitly stating that these are not formal tax advice. Assumptions exclude state and other taxes, and safe-harbor calculations are noted only to avoid penalties rather than represent a final liability. Users are directed to consult qualified professionals for actual tax obligations.
