Tips & Best Practices

  • Standard deduction simplifies filing - most taxpayers use it
  • Additional deductions (401k, IRA) reduce taxable income directly
  • Tax credits reduce your tax bill dollar-for-dollar, better than deductions
  • Your marginal rate is what you'd pay on additional income
  • Effective rate is your actual average tax rate on total income

Frequently Asked Questions

What is taxable income?

Taxable income is your gross income minus deductions. It's the amount the IRS actually taxes. For example, $75,000 income minus $14,600 standard deduction = $60,400 taxable income.

What's the difference between marginal and effective rate?

Marginal rate is the tax rate on your last dollar earned (your top bracket). Effective rate is your actual average rate - total tax divided by total income. Someone with $75,000 income might have 22% marginal rate but only ~12% effective rate.

Should I use standard or itemized deduction?

Most taxpayers benefit from standard deduction ($14,600 single / $29,200 married). Itemize only if your deductible expenses (mortgage interest, charitable donations, medical costs) exceed the standard amount.

What deductions can I add?

Common deductions: 401k contributions (up to $23,000), traditional IRA ($7,000), HSA contributions ($4,150 single / $8,300 family), student loan interest ($2,500), self-employed health insurance.

What tax credits can I claim?

Popular credits: Child Tax Credit ($2,000 per child), Earned Income Credit (low income), American Opportunity Credit ($2,500 education), Lifetime Learning Credit ($2,000), Saver's Credit (retirement contributions).
