1. Lesson 1: Marginal vs. effective rates

   A tax bracket applies to the next dollar earned, not to every dollar. Your effective rate — total tax divided by total income — is almost always lower than your bracket.

   • A raise that pushes you into a higher bracket only taxes the portion above the threshold at that rate.
   • Marginal rate is the number that matters when deciding whether a deduction or pre-tax contribution is worth it.
   • Ordinary income, long-term capital gains, and qualified dividends are taxed on different schedules.
   • State and local tax, payroll tax, and self-employment tax stack on top of federal income tax.

   Takeaway: Use your marginal rate to evaluate decisions and your effective rate to understand your total burden.

2. Lesson 2: Tax-advantaged accounts

   Account type changes the after-tax outcome of the same investment. The three broad treatments are pre-tax, after-tax growth, and taxable.

   • Pre-tax (traditional 401(k), traditional IRA, HSA): a deduction now, taxed on withdrawal. Best when your current rate is high relative to retirement.
   • After-tax growth (Roth 401(k), Roth IRA): no deduction now, qualified withdrawals are not taxed. Often favored early in a career.
   • Employer match is an immediate return on contribution — capturing the full match is usually the first priority.
   • HSAs, when you qualify, can offer a deduction, tax-free growth, and tax-free qualified medical withdrawals.
   • Contribution limits, income phase-outs, and eligibility rules change yearly. Confirm current figures before acting.

   Takeaway: Where you hold an investment can matter as much as what you hold.

3. Lesson 3: Deductions, credits, and records

   A deduction reduces taxable income; a credit reduces tax owed dollar for dollar. Credits are usually worth more, and documentation is what makes either survive scrutiny.

   • You take the greater of the standard deduction or itemized deductions — many households no longer itemize.
   • Common items worth reviewing with a professional: retirement contributions, HSA, education credits, dependent care, energy credits, and charitable giving.
   • Self-employed filers should track home office, mileage, health insurance, and qualified business income treatment carefully.
   • Keep receipts, mileage logs, and account statements contemporaneously. Reconstructed records are weak records.

   Takeaway: Bring organized records to a CPA and you buy strategy time instead of data-entry time.

4. Lesson 4: Entity basics for owners

   Sole proprietorship, LLC, S corporation, and C corporation differ in liability, self-employment tax, payroll requirements, and administrative cost.

   • An LLC is a legal structure; how it is taxed is a separate election.
   • S corporation treatment can reduce self-employment tax on distributions but requires reasonable owner compensation and payroll filings.
   • Entity choice affects how a future business acquisition is financed, structured, and eventually sold.
   • Getting this wrong is expensive to unwind. Decide with a CPA and an attorney who see your full picture.

   Takeaway: Pick the structure for the business you are building, not the one you read about.
