Using the right accounts can save you tens of thousands in taxes. A practical guide to 401(k)s, IRAs, and the order to fund them.

Choosing the right tax-advantaged accounts can save you tens of thousands of dollars over a career. This guide explains 401(k)s, IRAs, and a sensible order to fund them.

Key Takeaways

  • Why Account Type Matters: Where you hold investments can matter as much as what you hold, because taxes quietly erode returns.
  • Employer 401(k) Plans: A 401(k) lets you invest pre-tax dollars straight from your paycheck, lowering your taxable income today.
  • Traditional vs Roth: Traditional accounts give a tax break now and are taxed on withdrawal, while Roth accounts use after-tax money and grow tax-free forever.
  • Individual Retirement Accounts: An IRA is an account you open yourself, offering more investment choices than most workplace plans.

Why Account Type Matters

Where you hold investments can matter as much as what you hold, because taxes quietly erode returns. Tax-advantaged accounts let your money grow with taxes deferred or eliminated. Using them well can add tens of thousands of dollars over a career.

Key Points:

Account type affects after-tax returns
Taxes quietly erode growth
Tax-advantaged accounts shelter gains
Can save tens of thousands
Use the right account for each goal

Employer 401(k) Plans

A 401(k) lets you invest pre-tax dollars straight from your paycheck, lowering your taxable income today. Many employers match a portion of your contributions, which is free money you should always capture. Contribution limits are high, making it a powerful core account.

Key Points:

Invest pre-tax from your paycheck
Lowers taxable income today
Capture the full employer match
High annual contribution limits
A powerful retirement core

Traditional vs Roth

Traditional accounts give a tax break now and are taxed on withdrawal, while Roth accounts use after-tax money and grow tax-free forever. Roth shines if you expect higher future taxes or have a long horizon. Many people benefit from holding some of each.

Key Points:

Traditional is taxed later
Roth grows tax-free forever
Roth suits long horizons
Choose based on expected tax rates
Holding both adds flexibility

Individual Retirement Accounts

An IRA is an account you open yourself, offering more investment choices than most workplace plans. It comes in traditional and Roth versions with their own income and contribution rules. IRAs are ideal for money beyond your 401(k) or for rolling over old plans.

Key Points:

Open an IRA on your own
Wider investment selection
Traditional and Roth versions exist
Watch income and contribution limits
Great for rollovers and extra savings

A Smart Funding Order

A common priority is to capture the full 401(k) match first, then fund a Roth IRA, then return to max out the 401(k). After that, a taxable brokerage account offers unlimited, flexible investing. Adjust the order to fit your taxes and goals.

Key Points:

First capture the full match
Then fund a Roth IRA
Next max out the 401(k)
Then use a taxable brokerage
Adjust the order to your situation
