US income tax uses progressive brackets. You pay 10% on the first $11,600, then 12%, 22%, 24%, 32%, 35% and 37% on income above each threshold (2024 single filer). Your effective average rate is always lower than your marginal top-bracket rate because only income above each threshold is taxed at the higher rate.
Your marginal tax rate is the rate applied to the last dollar you earn — the highest bracket you reach. Your effective tax rate is total tax paid divided by total income — your actual average rate across all brackets. At $75,000 income as a single filer, your marginal rate is 22% but your effective rate is around 13-15%.
For single filers in 2024: 10% up to $11,600; 12% on $11,601 to $47,150; 22% on $47,151 to $100,525; 24% on $100,526 to $191,950; 32% on $191,951 to $243,725; 35% on $243,726 to $609,350; 37% above $609,350. Married filing jointly brackets are roughly double. The standard deduction ($14,600 for singles) reduces taxable income before brackets apply.
For US federal taxes in 2024: Single filers get $14,600. Married filing jointly get $29,200. Head of household get $21,900. The standard deduction reduces your taxable income before tax brackets apply. Only itemise deductions if your total deductible expenses exceed the standard deduction — most taxpayers benefit from the standard deduction.
Common pre-tax deductions that reduce taxable income include: 401k contributions (up to $23,000 in 2024), Health Savings Account contributions, Flexible Spending Account contributions, traditional IRA contributions if deductible, and self-employed health insurance premiums. Each dollar of pre-tax deduction saves money at your marginal tax rate.
In the UK for 2024-25: Personal Allowance is 12,570 pounds (0% tax). Basic rate 20% on income from 12,571 to 50,270 pounds. Higher rate 40% on income from 50,271 to 125,140 pounds. Additional rate 45% above 125,140 pounds. National Insurance adds approximately 8-12% on top for employees.
Legitimate tax reduction strategies include: maximising pension or 401k contributions, contributing to an ISA in the UK or Roth IRA in the US, claiming all eligible work-related deductions, using salary sacrifice schemes, making charitable donations, and using capital gains allowances. Consult a qualified tax professional for advice specific to your situation.
