Tax Guides: Brackets, Deductions and Smart Planning

Taxes touch almost every financial decision, from how much of your raise you actually keep to which retirement account makes sense and how to time a withdrawal. Yet the rules are spread across thousands of pages of IRS guidance and change every year.

This section explains the federal tax concepts most households run into: how marginal tax brackets work, the standard deduction versus itemizing, common credits, capital gains, and the tax treatment of 401(k)s, IRAs, Health Savings Accounts and Social Security benefits. Each figure comes from the IRS or another primary source and is labeled with the tax year it applies to, and we update yearly numbers when new figures are published.

FinancialAdviser.com is not a tax preparer and nothing here is tax advice. Tax outcomes depend on your full situation, including your state. Use these explanations to understand the rules and to ask sharper questions of a CPA, enrolled agent or other qualified tax professional.
