Here's how to invest that windfall for retirement if you're 40-something or older

Key Points
  • You can contribute up to $19,000, pre-tax, into a 401(k) for 2019 if you're under age 50.
  • If you have maxed out on your workplace plan, an individual retirement accounts — either Roth or traditional — can be another tax-advantaged option, depending on your income.
  • People age 50 and older also get to make "catch-up" contributions to 401(k)s and IRAs, and once you hit age 55 you can put an extra $1,000 in a health savings account.

Say you're a few decades into your career when you receive notice that you've inherited $20,000. The only condition is that it must be saved for retirement. So what's the best way to do that?

The answer depends on a combination of factors, including your income, your age and your existing savings. And that's before you even get to the point of choosing specific investments.

For people in their 40s — who often have settled into a career and are in their peak earnings years — it's common to have access to a 401(k) plan or similar option through work.

If you already participate, you could use some of that $20,000 windfall to max out on your contributions. And if you don't yet participate, now's the time to get started.

"I've seen some 40-somethings with millions in assets, and others that are just starting to save," said certified financial planner Sophia Bera, founder of Gen Y Planning.

For 2019, people under age 50 can can put up to $19,000 in their 401(k) plan.

Your contributions are pre-tax, which reduces your taxable income. Remember, too, that many companies will make a matching contribution — i.e., 50 cents or $1 for each $1 you put in — up to a certain amount, which is generally viewed as free money.

If you've maxed out on those 401(k) contributions or want other tax-advantaged options, an individual retirement account could work.

If you earn less than $137,000 (or $203,000 for married couples), you can put up to $6,000 into a Roth IRA for 2019. If your income is above the income limit, a Roth IRA is unavailable to you.

Although Roth contributions are not tax-deductible even for those qualify, earnings grow tax-free and withdrawals are completely tax-free once you reach age 59½, as long as you've owned a Roth for at least five tax years.

Be aware that while you generally can withdraw, at any time, any amount you contributed, taking out earnings before that minimum age could result in a tax penalty.

For a traditional IRA, you also can contribute up to $6,000 annually. However, if you have access to a 401(k) plan or similar workplace option, the tax break for contributions begins to phase out at modified adjusted gross income above $64,000 ($103,000 for married couples).

"You could still do a traditional IRA, but it might not be tax-deductible," Bera said.

For people not covered by a retirement plan at work, the rules are different. A single tax filer can deduct the full amount of their traditional IRA contribution (up to the limit) regardless of income. For married couples filing jointly, the deduction starts phasing out at modified adjusted gross incomes above $193,000.

Another option for some of that $20,000 windfall would be a brokerage account. While it would come with no built-in tax advantage, earnings from any investment held longer than one year would taxed at long-term capital gains rates, which generally are lower than the rates on regular income.

"A lot of times people have emergency savings and money going to their retirement accounts, but they don't have money in a taxable account," Bera said. "That's the kind of money that can help you retire early or meet other retirement goals."

Another way to save for expenses in retirement is through a health savings account, as long as you're enrolled in a high-deductible health plan.

While the money is not required to stay there until retirement, these accounts come with a triple tax benefit: contributions are tax-deductible, earnings grow tax-free and withdrawals are free of taxation as long as the money is used for qualified medical expenses.

"If you can put money in an HSA, it's a good idea," said CFP Rianka Dorsainvil, founder and president of Your Greatest Contribution. "The older we get, the more we're going to need medical care or prescriptions. So having that to pull out tax-free for medical expenses is a good decision."

As for the 50-and-older crowd, the options for that $20,000 windfall are slightly different due to higher contribution limits.

If you have a 401(k), you can put in an extra $6,000 — a "catch-up" contribution — for a total of $25,000 in 2019. Both traditional and Roth IRAs allow an extra $1,000 annually once you reach age 50, bumping your allowed contribution to $7,000 this year.

For health savings accounts, people age 55 and older can put an extra $1,000 in for a total of $4,500 ($8,000 for family coverage).
