Tax planning starts with understanding one mechanic most people get wrong: brackets tax slices of income, not the whole paycheck at one rate. This simulator renders the U.S. federal bracket ladder as a 3D scene — a segmented ruler shows every bracket's dollar range, a glowing marker slides to wherever your taxable income lands, and a coin-stack tower rises in each bracket to show exactly how many dollars were taxed at that rate. Adjust gross income, route money into a pre-tax 401(k)/IRA, and switch between Single and Married Filing Jointly to watch the marginal rate (the rate on your next dollar) and the effective rate (the average rate across all your income) update live — the two numbers that actually matter for tax planning decisions.
