Don't guess your payout—audit it.
Lottery Tax 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, Lottery Tax 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
Live Jackpot Data
Powerball and Mega Millions jackpots auto-fill with the latest real amounts and refresh automatically, so every audit starts from today's actual numbers—no manual lookups required.
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—even states that don't sell tickets but still tax winnings won elsewhere.
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.
Secure Local History
Unlike web calculators, Lottery Tax Audit features a dedicated History engine. Every calculation you generate can be saved directly to your device and synced privately through your iCloud account. Review past audits, compare different tax scenarios side-by-side, and keep a private record of your potential winnings without creating an account.
Detailed Payout Analysis
Lump Sum vs. Annuity: See a full 30-year graduated payment schedule to understand the long-term value of an annuity.
Group & Office Pools: Split a prize across any number of players and see each person's exact after-tax share.
Purchasing Power: Visualize your wealth with our tangible asset comparison tool.
Wealth Context: Compare your net payout against the GDP of entire nations.

Smart Persistence & Customization
A quick guided setup gets you started, then 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—translated end to end, right down to the asset comparisons.
Privacy-First Design
Your financial data is your own. Lottery Tax Audit operates entirely on-device. No personal financial data is transmitted to external servers, and no account creation is required.
Disclaimer: Lottery Tax Audit is for entertainment and estimation purposes only. It is designed to provide estimates based on publicly available federal and state tax data. It does not constitute official financial, legal, or tax advice. Lottery Tax Audit is not affiliated with, endorsed by, or associated with Powerball, Mega Millions, or any state lottery or government agency. Lottery payout rules, tax withholdings, and liabilities vary significantly by jurisdiction and individual circumstances. Winners are strongly advised to retain the services of a qualified tax attorney and a certified public accountant (CPA) before making any financial decisions.
