Planning for Taxes

Over a lifetime, taxes are often a family’s largest expense. Read only as rules, the code tells you what you owe. Read as incentives, it tells you what it will pay you to do.


Most people meet their taxes once a year, in April, looking backward. By the time a return is filed, nearly every decision that determines the tax bill has already been made. Filing is scorekeeping. The decisions were made across the years before: the kind of assets you own, how you own them, which accounts you funded, when income landed, what you sold and gave and converted. Those decisions have a design, and the design is not hidden. The code states what it will reward. Families who make those decisions deliberately keep meaningfully more of what they earn, entirely within the rules.

What the code rewards

Most of the tax code says what you owe. A large part of it does something else: it names things the government wants more of, and attaches a reward to each one. Retirement saving. Owning investments for years rather than months. Choosing the year a gain shows up, by which sale, which exercise, which account. Starting a business, hiring, buying equipment. Giving to charity. These are not loopholes anyone found. They are the stated purpose of whole sections of the law.

Fig. 1 — The rewards

Much of the tax code is a list of things the law will pay you for

Five of the largest, and the form each reward takes. Every one of them has to be claimed in the year it happens.

Behaviors the tax code rewards, and the form of each reward Five behaviors the law encourages, each paired with the form of its reward: retirement saving is rewarded with a deduction now or untaxed growth later; long holding periods with a lower rate than wages; choosing when income lands gives control of the year and the rate; business building brings deductions for hiring, equipment, and owner retirement plans; and charitable giving brings a deduction with no tax on the gain given away. WHAT THE LAW ENCOURAGES HOW IT PAYS Saving for retirement Holding for years, not months Choosing when income lands Building a business Giving to charity A deduction now, or growth that is never taxed later A lower rate than the one your paycheck pays You choose the year a gain shows up, and the rate that comes with it Deductions for hiring, equipment, and an owner’s retirement plan A deduction — and no tax at all on the gain you give away
Conceptual summary of why certain provisions exist; no rates, amounts, limits, or outcomes are implied, and nothing here indicates that a given provision is available to or appropriate for you. Eligibility, limits, and the treatment of each item depend on individual circumstances and change with law.

None of it works backward. A deduction has to be taken in the year the giving happened; a lower rate has to be earned by a holding period that already ran; a retirement contribution belongs to the year it was made. By the time a return is prepared, each of those doors has closed for the year.

First, how the brackets actually work

A tax bracket is the rate applied to a slice of your income, not to all of it. Moving into a higher bracket does not raise the tax on everything you earn. Only the dollars above the line pay the higher rate. This misunderstanding causes real families to fear raises and refuse income.

Fig. 2 — The staircase

Your top rate is not your real rate

Income fills the staircase from the bottom. Each slice pays its own step’s rate, so your overall rate is a blend — always lower than the top step you touch.

The first four 2026 federal marginal tax brackets as a staircase Four ascending steps of increasing rate, labeled with the first four 2026 federal marginal rates. Income fills from the bottom step upward; only the topmost slice pays the highest rate, so the blended effective rate sits well below the top step. 10% 12% 22% 24% YOUR NEXT DOLLAR first dollars earned last dollars earned your effective rate — the average you actually pay
The first four 2026 federal marginal rates. Source: IRS, Revenue Procedure 2025-32 (IR-2025-103, October 9, 2025). The rate schedule is the same for every filing status; the income thresholds it applies to are not, and both change with law. The current figures are always in The Tax Numbers. The structure holds regardless of the numbers: a raise, a withdrawal, or a conversion is taxed at the rate of the step it lands on, never backward across everything below it.

Two terms carry the rest of this subject. Your marginal rate is the rate on your next dollar, the top step you currently touch. Your effective rate is the blend you actually paid. The average. Nearly every good tax decision is a marginal-rate decision: what rate will this next dollar face, and is there a year in which it would face a lower one?

The brackets themselves — along with the year’s contribution limits, thresholds, and phase-outs — change most years, so they live in one place we refresh every January: The Tax Numbers. What follows is the part that doesn’t change.

What the drag costs

An unnecessary tax is charged once and paid twice. The second payment is everything those dollars would have earned if you had kept them, and it never appears on any return. Suppose a family pays $10,000 more than it had to, year after year, and suppose that money would otherwise have been invested.

Fig. 3 — What a leak becomes

An avoidable tax costs more than the tax

Tax paid is paid once and added to the pile. Tax avoided stays invested and keeps working. The two lines separate slowly at first.

A recurring tax, paid versus kept and invested Two lines rising from the same starting point over time. A straight dashed line represents the tax itself, added up year after year. A curved line represents the same money kept and invested instead, rising above the dashed line and separating further as time passes. The widening space between them is labeled as the part people miss. No amounts, rates, or outcomes are shown. the part people miss the tax itself, added up the same money, kept and invested one year many years later
Conceptual shape only. No amounts, rates of return, or outcomes are shown or implied, and the curves are drawn to illustrate an idea rather than to represent any investment, strategy, or result. Whether a particular tax can be avoided, and what happens to money that is not paid in tax, depends entirely on individual circumstances.

Two tax lives: the paycheck and the business

How the money reaches you decides which levers you have. A paycheck and a business are two different tax lives, and most families live some of each.

A paycheck is taxed the moment it is earned. The money is gone before it reaches your account, and there is very little to be done about the wage itself. What you can decide is what happens next. Wages carry the highest rates in the code. Assets are treated more gently: they grow without being taxed each year, they are taxed at lower rates when sold, and inside a retirement account they are not taxed along the way at all. Every dollar that makes that crossing is treated differently for the rest of its life.

Fig. 4 — The crossing

Every dollar that becomes an asset changes tax treatment for life

The arc of a working family’s tax life is one conversion, repeated: taxed income turned steadily into assets, until the assets carry the family instead of the paycheck.

Taxed income crossing into working assets A muted block labeled earned income, taxed on arrival at the highest rates, with an arrow crossing to a larger block labeled working assets, which are taxed only when sold, at lower long-term rates, or not at all inside retirement accounts. EARNED INCOME taxed on arrival withheld before you see it at the highest rates the code applies the crossing WORKING ASSETS growth compounds untaxed until you sell long-term gains taxed at lower rates retirement accounts defer
Conceptual illustration of how tax treatment differs by dollar type; no amounts, rates, or outcomes are implied. Treatment depends on account type, holding period, and individual circumstances, and rules change with law.

The crossing is open to everyone; the toolkits differ. A household on a paycheck still holds real levers: which accounts it fills, when options are exercised, when vested shares are sold, which year a gain lands. An owner holds those and more: how the business is organized, whether a bill is paid in December or January, a retirement plan that can hold several times what an employee’s can, equipment, family on the payroll doing real work. Different lists, one principle. The business itself, one day sold or never, is covered in Financial Planning for Business Owners.

Where planning pays: the windows

Tax planning is often a question of when. Income is not taxed evenly across a life, and the durable savings come from moving income and deductions deliberately between the high-rate years and the low ones.

Fig. 5 — The low-rate window

For many families the lowest-rate years of adult life arrive after the paychecks stop

Income tends to climb across a working life. It falls when the paychecks stop, and climbs again once withdrawals are required, since those start small and grow. The gap between is often the lowest-taxed stretch of an adult life.

The low-rate window between retirement and required withdrawals A timeline of adult life. Taxable income rises gradually through the working years, drops sharply into a highlighted low window after work ends, then climbs again as required withdrawals begin small and grow larger each year. THE WINDOW convert here, at today’s lower steps working years — income climbing work ends — withdrawals not yet required withdrawals begin small, and grow higher lower TAXABLE INCOME
Conceptual illustration of a common pattern, not a projection and not everyone’s pattern — no ages, rates, or amounts are shown or implied. The ages at which withdrawals become required, and whether a conversion is appropriate at all, depend on law and individual facts. Roth conversions carry current-year tax and are not suitable for everyone.

The high-income years work in the opposite direction. A large vest, a strong business year, the sale of an asset. Years like these reward concentrating deductions into them: charitable giving bunched into the high year, appreciated shares given instead of cash, income deferred past the spike where the rules allow.

Your accounts are themselves a set of windows. Which one you fund, which one you spend from, and which years you convert between them can add years to how long money lasts.

Fig. 6 — Three treatments

Every dollar you own sits in one of three tax treatments

Taxable, tax-deferred, and Roth differ mainly in when the tax is paid. Choosing which to fund, and which to draw from in which year, is where the planning happens.

The three tax treatments of accounts Three columns: taxable accounts taxed as you go, tax-deferred accounts taxed at withdrawal, and Roth accounts taxed once at contribution and then not again on qualified withdrawals. Taxable Tax-deferred Roth taxed as you go dividends, interest, and gains when sold taxed at withdrawal the deduction now, the bill later taxed once, at the start qualified withdrawals come out untaxed Not just which account. Which account, in which year.
Conceptual summary of general tax treatment; no rates, amounts, or outcomes are implied. Neither deferred nor Roth is better in general: deferred tends to win when today’s rate is higher than the rate you expect at withdrawal, and Roth when it is lower. Eligibility, contribution limits, holding-period requirements, and the conditions for a qualified withdrawal all depend on law and individual circumstances.

The generational window is the longest of them, and for some families it never closes. Large outcomes are settled by what is gifted, what is sold, and what is deliberately never sold. Assets held until death have historically passed with a step-up in basis that a lifetime sale would have given away. Decisions at this scale want years of runway, and they want your attorney, your CPA, and your planner working the same problem together rather than one at a time.

Someone has to hold the whole picture: look across the accounts and the years, put the plan together, and get the CPA and the estate attorney into the conversation early. Three sets of hands on one problem is rarer than it ought to be. They confirm the tax treatment, file the returns, and draft the documents. Filing answers for the year that ended. Planning answers for the years still ahead, however far ahead a family is thinking.

Taxes inside the portfolio

Tax planning is not a separate appointment from investing. Nearly every portfolio decision is also a tax decision.

What you own has a tax character. A business that reinvests its earnings compounds them for you untaxed until you sell. A holding that pays out heavily hands you income every year, wanted or not, and interest is taxed at higher ordinary rates than qualified dividends. A fund that trades constantly distributes gains you never asked for. None of this decides what to own on its own. A good business is a good business. But it belongs in the decision.

Where each holding sits matters as much as what it is. The same investments, arranged well across account types, keep more before anything is bought or sold.

Fig. 7 — Placement

The same holdings, arranged differently, keep different amounts

Heavily taxed income is generally better sheltered; holdings that defer their own tax are generally fine in the open. Then cash-flow needs get a vote over all of it.

Asset location across account types A grid of holding types against three account types. Holdings that defer their own tax sit naturally in taxable accounts; interest income, high payout, and high-turnover holdings sit naturally in tax-deferred accounts; the highest-growth holdings sit naturally in Roth. A band across the bottom notes that cash-flow needs can override the arrangement. TAXABLE TAX-DEFERRED ROTH Retains its earnings, pays little out Pays heavy dividends Interest income, REIT distributions Trades often, distributes gains Highest expected growth The open circles would work too — sheltered is sheltered. Gold marks where each dollar does the most: Roth space is limited and never taxed again, so it goes to whatever will grow the most. What the family needs to spend gets a vote over all of it.
Conceptual illustration of general tax treatment, not a recommendation and not a portfolio. No specific securities, rates, or outcomes are implied. Income-heavy holdings would be sheltered inside a Roth as well; the placements shown put the fastest compounding where it is never taxed again, which tends to matter more the longer the horizon. Which arrangement is appropriate depends on tax bracket, account capacity, time horizon, and income needs, and rules change with law — an arrangement that is efficient on paper is wrong if it cannot pay for a family’s life.

How long you hold, and how often you trade, belong in the same calculation. Gains held beyond a year are taxed at a lower rate, and every sale hands over money that would otherwise still be working. Buffett has made the point with a punch card: if you were allowed only twenty investment decisions in a lifetime, you would make each one count. The arithmetic runs the same direction, not in every case, and some who trade often do well, but reliably enough that we build around it. Selling still has its place, and there are good reasons to sell: a business that has stopped being what you bought, a position so large it keeps you up at night, a need the portfolio has to meet. The discipline is buying well enough that few sales are necessary.

Losses are worth something if you use them. When a holding is worth less than you paid for it, selling it turns a paper loss into a real one that can offset gains elsewhere and, within annual limits, some ordinary income. Whatever you don’t use carries forward to later years. One rule governs the mechanics: buy back the same investment within thirty days and the loss is disallowed, so the repurchase is planned rather than improvised.

Now the part that is easy to miss, and worth walking through slowly. Say you paid $100 for something and it falls to $60. You sell, and that $40 loss cancels $40 of gains you owed tax on. Real money saved this year. Then you buy back in at $60. That $60 becomes your new cost. If the investment climbs back to $100 and you eventually sell, your gain is $40 rather than nothing, and the tax comes due then. The loss you spent early returns as a gain later.

So harvesting usually moves tax rather than erasing it. Moving it is worth real money: what you keep this year stays invested until the bill arrives, which is the same shape as the figure above. And sometimes the bill never arrives at all. If that holding is eventually given to charity, or held until it passes to heirs, the gain you deferred may never be taxed to anyone.

Drawing income has its own design. A family living on its portfolio decides how much to take, which accounts to take it from, and in what order. At higher brackets, what the income itself is made of. Municipal bond interest is generally exempt from federal tax, and in high-tax states like California and New York, in-state issues generally escape state tax as well. For a household in the top brackets, that exemption can be worth more after tax than a higher stated yield somewhere else, and a meaningful allocation can cover a good share of what a family spends with little or no tax attached to it. Paired with deliberate loss harvesting, particularly in a year when a large gain is already coming, the combination is one of the more useful things available at that level of wealth. Whether it fits any given household depends on the bracket and the year, and that is a calculation, not an assumption.

None of this is exotic, and none of it depends on a clever year. It is the part of tax work done inside the portfolio, every year.

The ethic

Answering the incentives is doing what the rules were written to encourage. Nobody found a loophole.

Saving for retirement. Giving to charity. Holding investments for years instead of days. Building a business, hiring, investing in equipment, passing wealth on deliberately. Congress wanted more of each, so each carries its own reward. Courts have said for a century that no one owes a penny more than the law requires. Paying all you owe and nothing you don’t is stewardship of the same money that funds your family and your giving.

Where this lands

The rules will change more than once over your life. The shape of it doesn’t. In your expensive years, defer what you can and give from what has grown. In your cheap years, convert and realize. Move earning from wages to assets as the years allow, and claim what the law offers in the year it offers it.

None of that takes brilliance. It takes knowing your own numbers, thinking in decades, and doing the ordinary thing on time each year, for enough years that it adds up to real money kept.

What to carry away
  • By the time a return is filed, the tax bill is already set. The decisions that set it were made in the years before, in what you funded, sold, gave, and converted.
  • Much of the code is a list of things the law will pay you for — saving for retirement, holding for years, choosing when a gain lands, building a business, giving to charity. None of it works backward; each has to be claimed in the year it happens.
  • Brackets are a staircase. Only the dollars above each line pay that step’s rate, so your effective rate — the average — always sits below your top bracket.
  • An unnecessary tax is paid twice: once to the government, and again in everything those dollars would have earned.
  • How the money reaches you decides which tools you have. A paycheck is taxed on arrival; an owner has a longer list of choices. Every dollar that crosses from income into assets is treated differently for the rest of its life.
  • The savings live in windows — the low-rate years after work ends, the high-income year that rewards concentrated giving, and the generational decisions that want years of runway.
  • Every dollar sits in one of three treatments: taxable, tax-deferred, or Roth. Not just which account, but which account in which year.
  • Inside the portfolio, what you own has a tax character, where you hold it matters, patience is rewarded with a lower rate, and losses are worth something if you use them — though harvesting usually moves the tax rather than erasing it.
  • Drawing income is its own design: how much, from which accounts, in what order, and at higher brackets what the income is made of.
  • Expensive years are for deferring and giving; cheap years are for converting and realizing. Know which kind of year you are in, and keep at it long enough for the arithmetic to add up.
