CasinoReviews.net rolled out its US Gambling Tax Calculator last week. The London company timed the launch for International Accounting Day on November 10. The tool went live ahead of the 2025 tax filing season.
Five states got access at launch. Pennsylvania, Ohio, New Jersey, Michigan and New York players can use it now. More states join the platform in Q1 2026.
The company’s Product Owner is Nikoleta Kuncheva. Lead Engineer Christian Dimitrov handled the technical build.
Why Flat-Rate Calculators Miss the Mark
Most gambling tax calculators use flat rates. But that’s not how the IRS works.
“Most calculators treat gambling taxes like a flat fee. They aren’t,” Kuncheva said. The tool models progressive federal tax brackets instead. It layers state rules on top of federal calculations.
Early testing showed problems with flat-rate tools. These simple calculators can miss the actual tax bill by 15-25% in common situations. The new calculator cuts that gap significantly.
Different filing statuses matter too. A single filer and married couple filing jointly face different bracket thresholds. The calculator accounts for these variations. State tax overlays add another layer of accuracy.
What Makes This Calculator Different
The tool uses two-layer outputs. It calculates federal progressive brackets first. Then it applies state-specific rules.
Filing status determines the bracket calculation. The system handles single, married filing jointly, and other IRS categories. Each status has different income thresholds for tax brackets.
State logic covers the five launch markets completely. New Jersey, Ohio, Pennsylvania, Michigan and New York each have unique gambling tax rules. The calculator includes these specific requirements.
County surcharges exist in some areas. The initial version has MVP scope for these local add-ons. Future updates will expand this coverage.
The system doesn’t store personal data. Calculations happen without saving user information.
How the Platform Ensures Accuracy
Dimitrov’s team validated everything against IRS examples. They checked calculations against each state’s 2025 bracket tables. The validation process covered official tax documents.
Testing went beyond basic scenarios. The team ran unit tests on over 200 different situations. They tested across all filing statuses. Each scenario checked federal brackets combined with state rules.
The result gives players closer estimates to their actual tax obligations. It won’t replace professional tax advice. But it beats flat-rate calculators by a significant margin.
More states coming next quarter will make the tool more useful. As coverage expands, more US gambling players get access to accurate tax estimates before they file.
