Where Do Software Engineers Actually Keep the Most Disposable Cash?
Gross salary comparisons lie. In the United States alone, you face stacked Federal, State, and Municipal income taxes—plus private health insurance premiums, deductibles, and $25,000/yr daycare. In New Zealand, Australia, and Europe, universal healthcare or subsidized childcare comes with your taxes, but consumption taxes (15% GST / 20% VAT), high fuel excises, and statutory Road User Charges (RUCs) quietly erode purchasing power.

Why Headline Tax Rates & CPI Indices Fail Software Engineers
Every jurisdiction funds public goods differently. A city with 0% state income tax often recoups revenue through property taxes, toll roads, or private insurance mandates. Below are the four structural pillars modeled in this engine.
1. Multi-Tier Income & Payroll Taxes
Federal + State/Canton + Municipal + Social Levies
2. What Taxes Buy vs. Self-Funded Gaps
Healthcare, ACC, & Early Childhood Education
3. Configurable Retail Handbasket & GST/VAT
Itemized Groceries, Coffee, Dining & Exemptions
4. Petrol Excise, EV Power & RUCs
Road User Charges, Rego, Tolls & Singapore COE
