Tax-Advantaged Accounts for Every Goal

Two people can save the same amount for the same goal and end up with very different results, simply because one used an account the tax code favors and the other did not. The federal government offers tax breaks for saving toward retirement, health costs, education and childcare, each through its own account with its own rules. This chapter matches each goal to its account, gives the 2026 limits, and suggests an order for filling them when money is limited.

Why the account matters

A tax-advantaged account helps in one or more of three ways: the money goes in before income tax, it grows without yearly tax on interest, dividends or gains, or it comes out tax-free when used for the account's purpose. To see what a deduction is worth, you need your marginal rate, the rate on your last dollar of income. For a single filer earning $85,000 in 2026:

After the standard deduction of $16,100, taxable income is $68,900 and the top bracket reached is 22.0%, even though total federal tax is only 11.6% of gross income. Each dollar this person puts into a pre-tax account lowers federal tax at that 22.0% rate, before any state tax saving. The tax bracket calculator shows your own.

The 401(k): start with the match

A workplace 401(k) or 403(b) has the highest employee limit of any account: $24,500 in 2026, plus $8,000 for workers 50 and older. Contributions come straight from payroll, which makes them the easiest to automate.

The match is the reason it usually comes first. A plan that matches 50% of contributions up to 6% of pay adds 3% of pay for a worker who contributes 6%. On a salary where that 3% comes to about $188 a month, the match alone, invested for a career, grows like this:

That is about $219,272 at an assumed 7.0% a year, all from money the employer adds only if you contribute. Check your plan's vesting schedule, which can require a few years of service before the match is fully yours.

Most plans offer traditional (pre-tax) and Roth (after-tax) contributions. Traditional saves tax now and is taxed on withdrawal; Roth costs tax now and comes out tax-free in retirement if the rules are met. The choice turns on whether your tax rate is likely to be higher now or later, and many people hold some of each so they have options later. Retirement Planning Fundamentals, in the library, covers the choice in depth.

The one move to avoid is cashing out an old 401(k) when you change jobs. Before 59½ that generally means income tax plus an additional 10% tax, and the money leaves tax-sheltered growth for good. Roll it to the new plan or an IRA instead.

IRAs: flexible space beside the workplace plan

An individual retirement account has a lower limit, $7,500 in 2026 plus $1,100 at 50 and over, but you choose the provider and the investments. A Roth IRA has a feature that matters for a savings plan with several goals: your own contributions (not the earnings) can be withdrawn at any time without tax or penalty. That makes it a reasonable second line of reserve, though money taken out cannot be put back beyond the yearly limit.

Direct Roth IRA contributions phase out above certain incomes. The 2026 phase-out begins at modified adjusted gross income of $153,000 for single filers and $242,000 for married couples filing jointly. Above the range, some people use a "backdoor" Roth: a non-deductible traditional IRA contribution followed by a conversion. If you hold other pre-tax IRA money, the pro-rata rule makes part of the conversion taxable. The backdoor Roth calculator shows the effect.

The HSA: three tax breaks in one account

A health savings account is the only account that is deductible going in, grows tax-free, and pays out tax-free for qualified medical costs. Contributions through payroll usually skip Social Security and Medicare tax too. A few states, including California and New Jersey, do not follow the federal treatment and tax HSA contributions.

You can contribute only while covered by an HSA-eligible high-deductible health plan, which in 2026 means a deductible of at least $1,700 for self-only coverage or $3,400 for family coverage. The 2026 contribution limits are $4,400 for self-only coverage and $8,750 for family coverage, plus $1,000 at 55 and older. Unlike a flexible spending account, the money is yours to keep, year after year and from job to job.

Many people spend their HSA each year. A different approach, if you can afford it, is to pay current medical bills from your regular budget, keep the receipts, and leave the HSA invested. Qualified expenses can be reimbursed years later, as long as they were incurred after the HSA was opened. Here is about $366 a month, close to the self-only limit, invested for 25 years:

At an assumed 7.0% a year it grows to about $286,593. After 65, withdrawals for non-medical costs are taxed like a traditional IRA but carry no penalty; before 65 they also face an additional 20% tax. Whether a high-deductible plan suits you depends on your health costs; the HDHP vs PPO calculator compares them, and the HSA retirement calculator projects the long-term value.

529 plans: education savings

A 529 plan lets savings grow free of federal tax, and withdrawals are tax-free when spent on qualified education: college and graduate school tuition, fees, books, and room and board for students enrolled at least half time, plus K-12 tuition up to an annual limit, registered apprenticeship costs, and some student loan repayment up to a lifetime limit. Many states give a deduction or credit for contributing to their own plan. The beneficiary can be changed to another family member if the first child does not need the money.

Starting at birth with $250 a month:

After 18 years at an assumed 6.0%, the account holds about $95,240, of which $41,240 is growth that is tax-free if spent on qualified costs. Earnings withdrawn for anything else are taxed and usually face an additional 10% tax.

Since 2024, unused 529 money can move to the beneficiary's Roth IRA, up to a lifetime total of $35,000. The 529 account must have been open at least 15 years, contributions from the last five years do not qualify, each year's rollover counts against the beneficiary's IRA limit, and the beneficiary needs earned income. It softens the risk of saving "too much," but does not remove it.

Flexible spending accounts: use it or lose it

A health FSA, offered through an employer, lets you set aside pre-tax pay for medical, dental and vision costs. The 2026 limit is $3,400. Unspent money is generally forfeited, though a plan may allow either a carryover of up to $680 or a grace period of up to two and a half months, not both. Elect only what you are confident you will spend: start from last year's actual costs and add planned care.

A dependent care FSA covers daycare, preschool, before- and after-school care and day camps for children under 13 so that you can work. Federal law raised its household limit starting in 2026; check the amount in your employer's plan documents. It interacts with the child and dependent care tax credit, since the same expenses cannot be used for both, so compare the two with your plan administrator's figures or a tax preparer.

An order for filling the accounts

When money is limited, a common order is:

1. Contribute to the workplace plan up to the full match.
2. Fund the HSA, if you are eligible.
3. Fund a Roth or traditional IRA.
4. Raise workplace contributions toward the limit.
5. Use a taxable brokerage account for anything beyond, or for goals before retirement.

A 529 sits beside this list rather than in it, funded when education is one of your goals and the retirement steps are on track. An FSA is a once-a-year election for costs you know are coming. Adjust the order to your situation: no match means step 1 drops out, high plan fees may move the IRA up, and high-interest debt usually comes before steps 2 to 5.
