- •Allocation is proportional to published spending, not a trace of your actual dollars. No specific payment funds a specific programme.
- •Governments run deficits, so total spending exceeds total tax revenue. These shares show the composition of spending, not a balanced ledger.
What to check before trusting this
- •State figures are for tax year 2025 and every one has been cross-checked against the state's own published schedule or its enacting legislation (audited 2026-09-08). Confirm against the state revenue department before filing.
