Save a Headache Now: Take a Bracket Peek Before Year-End

A bracket peek is ten minutes of rough math. It shows where this year's taxable income sits and how far it is to the next line. That one picture changes what you can still decide before December 31.

Some of these choices close with the year. The peek is how you see them while they're still open. Here's how the steps work, the 2026 lines, and five things the peek lets you do.

Federal income tax brackets work like stairs. Each step has its own rate, and only the income on that step is taxed at that rate. Moving up a step doesn't reprice the steps below it.

So "I'm in the 24% bracket" means the last dollars are taxed at 24%. It doesn't mean every dollar is. Two numbers answer two different questions:

Year-end decisions happen at the top step. That's why the top rate is the one to look at first.

For tax year 2026, these are the federal income tax brackets on taxable income, from the IRS (IR-2025-103, Oct 9, 2025): the IRS release

The 2026 standard deduction is $16,100 for single filers and $32,200 for married couples filing jointly (same IRS release). These are federal figures on taxable income, which is not the same as revenue or profit. State tax is separate, and tax law can change.

Hypothetical, round numbers, not anyone's actual return. Married filing jointly, 2026 federal brackets, ordinary income tax only, no credits.

Look at those two rates. It's shocking how many people think their whole income is taxed at their top bracket. This couple is in the 24% bracket, but 24% of $250,000 would be $60,000. Their federal income tax on the brackets is about $45,200, because only the $38,600 above $211,400 is taxed at 24%. The 24% is the marginal rate: what the next dollar costs. The 18% is the effective rate: the bracket tax divided by the $250,000 of taxable income.

The tip: when you do your peek, write down both. Use the top rate to frame a December move. Use the effective rate to see the bracket tax as a share of taxable income.

Keep that couple in mind. They're the example under each of the five things below. Whether any move makes sense is a separate question, with tradeoffs beyond tax. The tax preparer runs the real numbers, including credits, state tax, and everything else on the return.

1. Time a bonus or distribution with this year's room in mind.

Example: say the couple owns a C corporation and is weighing a $40,000 year-end bonus. That would take them to about $290,000, still on the 24% step and well short of $403,550. If the same bonus would cross the next line, December versus January becomes a real question. A C corporation distribution is a dividend, taxed at different rates and not deductible to the corporation. In a pass-through, the math works differently, because the profit already flows to the personal return whether it's paid out or not. Which case you're in is part of the plan, and your tax preparer runs the exact numbers.

2. Decide whether an equipment or truck purchase is worth pulling into this year.

Example: if the business is a pass-through, a deduction comes off the owner's top step first. For the couple, that would be the 24% step. In a lighter year sitting on the 12% step, the same purchase comes off a lower step. If the business is a C corporation, the deduction lands on the corporation's return instead. How much of a purchase counts this year depends on depreciation rules your tax preparer applies. The peek doesn't make the truck a good idea. It shows what the timing means on the tax side, so the decision can rest on whether the business needs the truck.

3. See whether there's room for a Roth conversion.

Example: a conversion adds taxable income this year. The couple has about $153,550 before the 32% line. That's the room question in one number. Whether a conversion fits at all is a bigger question: cash to pay the tax, time horizon, and what next year looks like. It's a tradeoff, and the answer might be no.

4. Size a retirement contribution.

Example: pre-tax contributions lower taxable income, and they come off the top step first. Roth contributions don't lower it now. For the couple, a pre-tax dollar comes off the 24% step this year, which frames the pre-tax versus Roth question. Some plan deadlines run past December 31 and some don't, so the timing belongs on the list too. Your tax preparer runs the exact figures and files.

5. Spot whether a December move crosses another line.

Brackets aren't the only lines. Long-term capital gains have their own rates. The qualified business income deduction changes above certain incomes. Investment income can add the 3.8% net investment income tax above certain incomes. For anyone on Medicare, premiums can step up based on income from two years earlier. Example: selling a winner in December adds a long-term gain. The gain is taxed at its own capital gains rate, not the 24% step, but it still raises the couple's income and could cross one of those other lines. Which ones apply to you is part of the plan, and your tax preparer runs the exact numbers.

That puts you near this year's taxable income. Find it on the table. Note the step you're on and how far the next line is. If the business is a pass-through, its profit usually flows to your personal return, and your tax preparer handles how your entity reports. It's a sketch, not a return.

After I sold Vala Secure in 2022, the number one issue was the tax bill. Not long after, I bought a commercial building, partly for the tax benefits. It left me asset-rich and cash-poor.

The lesson stuck. A move that looks good on the tax side still has to fit the rest of the plan: cash, timing, and what comes next. The bracket peek is the first look, not the whole decision.

Tax strategy is part of the plan. I lay out the choices and tradeoffs, you decide, and your tax preparer carries it out and files.
