Understanding the U.S. Tax System: A Comprehensive Guide
Progressive Tax System Explained
The U.S. uses a progressive tax system where tax rates increase as taxable income increases. This means you don't pay the same rate on all your income - you pay different rates on different portions of your income based on tax brackets.

Frequently Asked Questions
Should I itemize or take the standard deduction?
Itemize only if your total itemized deductions exceed the standard deduction. Common itemized deductions include state taxes, mortgage interest, and charitable contributions.
How do I minimize my tax liability legally?
Maximize retirement contributions, use tax-advantaged accounts (HSA, FSA), consider tax-loss harvesting, and time income and deductions strategically.
When should I make estimated tax payments?
If you expect to owe $1,000+ in taxes and your withholding/credits cover less than 90% of current year tax or 100% of prior year tax (110% if AGI > $150,000).
What records should I keep for taxes?
Keep tax returns for 7 years, supporting documents for 3-6 years, and records of non-deductible IRA contributions permanently.

Marriage can result in a "bonus" or "penalty" depending on income levels. Generally beneficial when incomes are very different, potentially costly when similar and high.
