Bringing It All Together

You started this course flinching at the word "taxes." Now you know more than 90% of the people you work with — including some of the people who do their own taxes badly every year.

Let's pull everything into a single checklist. Run through this every December, and you'll capture nearly every legal tax move available to a normal person.

Income & Withholding

• Estimate this year's total income and compare to last year;
• Check your YTD federal withholding — are you on track? Adjust your W-4 if you're way off;
• If you owe quarterly taxes, verify Q4 (due January 15) is correctly sized — or crank up W-2 withholding instead;
• Compare your projected tax against the safe harbor (100% / 110% of last year, or 90% of this year).

Retirement Accounts

• Max your 401(k) if cash flow allows ($24,500 for 2026; $32,500 if age 50+);
• Confirm you grabbed every dollar of employer match — never leave this on the table;
• Max your IRA or Roth IRA ($7,500 for 2026; $8,600 if 50+) — you have until tax filing deadline;
• If you have an HSA, max it ($4,400 self-only / $8,750 family, 2026) — the triple-tax-advantaged king.

Investment Moves

• Review your taxable accounts for tax-loss harvesting opportunities before December 31;
• Confirm no wash sale violations across all your accounts (including spouse's and IRA);
• If you're in the 0% capital gains bracket, consider intentionally realizing long-term gains;
• Check asset location — are tax-inefficient investments (REITs, bond funds) inside tax-advantaged accounts?

Deductions & Credits

• Project whether you'll itemize or take the standard this year (standard: $16,100 single / $32,200 joint for 2026);
• If close to itemizing, consider bunching charitable gifts into one year (or use a DAF);
• Donate appreciated stock instead of cash for double tax benefit (no gain + full deduction);
• Run through above-the-line deductions: student loan interest, HSA, IRA, educator expenses ($350 for 2026), self-employment health insurance;
• Don't forget the new 2026 above-the-line charitable cash gift ($1,000 single / $2,000 joint) for non-itemizers.

Gifts & Family

• Used your $19,000 annual gift exclusion to anyone you want to gift? It resets every January 1;
• Contributing to 529 plans for kids/grandkids? Check your state's deduction;
• Reviewed beneficiaries on all retirement and insurance accounts.

Documentation

• Receipts for charitable donations above $250;
• Mileage logs (charity, business);
• 1099s, K-1s, brokerage statements organized;
• Property tax and mortgage interest statements (Form 1098);
• HSA contribution and distribution records.

Filing Strategy

• Single W-2, standard deduction → DIY software;
• Side income or freelance → consider an EA;
• Business owner → consider a CPA;
• Major life event (marriage, divorce, inheritance, big stock sale) → talk to a pro this year;
• Made significant gifts above $19k to one person → file Form 709 (no tax owed, just disclosure).

What You've Earned

Look at what you can now do that you couldn't a few hours ago:

• Explain marginal vs effective rates — and stop fearing raises;
• Know when to itemize, and which deductions live above the line;
• Tell credits from deductions — and which beats which;
• Hold for long-term capital gains — and find the 0% bracket;
• Place income-heavy investments in the right accounts;
• Rank your tax-advantaged accounts in the right order — and treat the HSA like the king it is;
• Harvest losses without tripping wash sale rules;
• Tune your W-4 so the IRS doesn't get a free loan;
• Handle quarterly taxes — or use withholding magic to skip them;
• Decide between DIY software, an EA, a CPA, and a CFP;
• Stay calm if a correspondence audit ever shows up.

What's Next

You've finished the foundation. From here:

• Run the year-end checklist above this December — even just half of it will likely save you more than this course took to complete;
• Set a calendar reminder for January to update your W-4 and check IRA / HSA contribution room;
• Bookmark the IRS Tax Withholding Estimator — use it whenever life changes;
• Save this course as your reference. You'll come back to specific chapters as situations come up.

Taxes will never be fun. But you no longer hate them — because you know how they work, where the moves are, and how to keep more of what you earn.

Welcome to the other side.
