United States federal government FY2025: US Treasury, Monthly Treasury Statement Table 5, net outlays by agency for the fiscal year ended 2025-09-30, with the four largest agencies split into their published components. Medicare and Medicaid, Social Security and interest on the debt are shown separately from the departments that administer them, because reported as agencies they are three unreadable lines.

- •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
- •California's personal exemption is a $153 credit against tax, not a deduction from income.
- •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.
This assumes you claim nothing
The figures above are a salary with the standard deduction and no credits. Upload your bank statements and tax.ing reads every charge, finds the deductions you are entitled to, and argues against each one before showing it to you.
Effective rate and marginal rate are not the same number
Your marginal rate is what the next dollar you earn is taxed at. Your effective rate is what you actually pay across everything. They differ because income tax is charged in slices: the first slice is taxed at the lowest rate whatever you earn, and only the last slice is taxed at the top rate. Someone in British Columbia on CA$500,000 has a marginal rate of 53.50%, but pays 44.13% overall, because the 53.50% only touches income above CA$259,829.
This is why a headline top rate tells you very little about a tax bill, and why moving into a higher bracket never leaves you worse off.
What is included
Federal income tax, state or provincial income tax, and payroll contributions: Social Security and Medicare in the United States, CPP and EI in Canada. Surtaxes and levies that sit outside the rate schedule are included too, such as the Ontario surtax and the Ontario Health Premium, which most bracket calculators miss entirely. Local income tax is estimated separately for the ten US states that levy it.
Figures assume a single earner with employment income and the standard deduction, with no dependants or other credits. Every 2026 bracket has been checked against the revenue department that publishes it.
