💡 Did You Know?
📖 How Billionaire Tax Analysis Works
We model wealth growth using compound annual growth, then apply current vs. proposed tax rates to the growth. Tax avoidance strategies reduce effective payment.
Step 1: Wealth Growth
Future Wealth = Initial × (1 + growth rate)^years. Wealth Growth = Future − Initial.
Step 2: Tax Comparison
Current Tax = Wealth Growth × Current Rate. Proposed Tax = Wealth Growth × Proposed Rate. Additional Revenue = Proposed − Current.
Step 3: Avoidance Multipliers
Buy-borrow-die: ~15% of theoretical tax paid. Stock-based loans: ~25%. Offshore: ~35%. Charitable: ~45%.

❓ Frequently Asked Questions
How do billionaires avoid taxes?
Buy-borrow-die: borrow against stock, never sell. Step-up basis at death wipes capital gains. Charitable trusts, offshore structures, and timing also reduce taxes.
Wealth tax vs. minimum tax?
Wealth tax = annual % on net worth. Minimum tax = floor on effective rate including unrealized gains. Minimum is often seen as more administratively feasible.
Why do billionaires pay less than workers?
Wealth comes from unrealized gains (not taxed until sold). Capital gains rates are lower than wage rates. Sophisticated planning unavailable to typical workers.
How much revenue could reform generate?
Estimates: $200–400B over 10 years for minimum tax. Depends on design, enforcement, and behavioral response.
What is stepped-up basis?
At death, heirs inherit assets at current value — prior gains are never taxed. Eliminates capital gains on inherited wealth.
Arguments for and against?
For: fairness, revenue, inequality. Against: complexity, capital flight, effects on investment. Debate is ongoing.
