LottoAudit

Don’t guess your payout—audit it.

Lotto Audit is the professional standard for lottery tax estimation. While advertised jackpots grab headlines, the actual "take-home" amount is often drastically lower after federal withholding, state liabilities, municipal taxes, and hidden surcharges.

Designed for accuracy and privacy, Lotto Audit goes beyond simple estimation. It serves as a secure, local database for your financial scenarios. Whether you are analyzing a Powerball jackpot, Mega Millions drawing, or a custom windfall, this app breaks down every dollar of liability so you can plan with confidence.

KEY FEATURES

Secure Local History Unlike web calculators, Lotto Audit features a dedicated History engine. Every calculation you generate can be saved directly to your device. Review past audits, compare different tax scenarios side-by-side, and keep a private record of your potential winnings without creating an account.

Precision Tax Engine Our algorithm includes up-to-date tax brackets and rules for:

Federal Tax: Automatically calculates the mandatory 24% withholding versus the final 37% tax liability due at tax time.

State Taxes: Includes specific tax rates for all 50 states and territories.

Hidden Surcharges: Automatically detects and alerts you to "Millionaire’s Taxes" and high-income surcharges in states like Massachusetts and New Jersey.

Municipal Taxes: Granular city-level tax selection for major jurisdictions including New York City and Yonkers.

Smart Persistence & Customization The app learns your preferences. Your filing status, state of residence, and dependency counts are securely stored locally, saving you from repetitive data entry. The interface adapts to your needs with full support for Dark Mode and 13 international languages.
