What to Do After Maxing Out Your 401(k) and IRA: Retirement Investment Strategies

Financial experts agree that everyone should save for retirement. Social Security and pension plans probably will not provide enough money to sustain your current standard of living during retirement, so it is up to you to provide the difference. The two most popular retirement savings tools are the 401(k) and similar employer-sponsored plans, such as the 403(b) and Thrift Savings Plan, and the Individual Retirement Arrangement (IRA).

But what happens when you have maxed out both? This guide covers what to do with additional savings once you have reached the contribution limits on your primary retirement accounts.

Step 1: Max Out Your Retirement Accounts First

Before looking at options beyond your 401(k) and IRA, make sure you have fully optimized your tax-advantaged accounts. Here is the recommended order of operations:

First: Contribute enough to your 401(k) or TSP to capture the full employer matching contribution. This is free money you should never leave on the table. For military members under the Blended Retirement System, the government matches up to 5% of base pay.

Second: Max out a Roth IRA if you are eligible. For 2026, the limit is $7,500 per person or $8,600 if you are age 50 or older. The Roth IRA’s tax-free growth and withdrawal flexibility make it one of the most valuable accounts available.

Third: Max out your 401(k) or TSP contributions beyond the match. For 2026, the limit is $24,500 or $32,500 if you are age 50 or older.

Once you have reached these limits and still have additional funds to invest, consider the following options.

Step 2: Maximize Your HSA If You Are Eligible

Before moving to taxable investments, consider whether you are eligible for a Health Savings Account. The HSA offers a triple tax advantage: tax-deductible contributions, tax-free growth, and tax-free withdrawals for qualified medical expenses, making it arguably the most tax-efficient savings vehicle available.

For 2026, the HSA contribution limit is $4,400 for individual coverage and $8,750 for family coverage. HSA contributions do not count against your IRA or 401(k) limits, meaning you can max out all three in the same year.

To contribute to an HSA, you must be enrolled in an HSA-eligible high-deductible health plan. For military members, most active-duty personnel enrolled in Tricare are not eligible, but those who have separated or have civilian employer coverage through the Guard or Reserve may qualify. See our complete guide to using your HSA as an investment vehicle for more details.

Step 3: Reevaluate Your Financial Priorities

Before investing additional funds in taxable accounts, step back and evaluate your overall financial picture. Consider:

• Do you have any non-mortgage high-interest debt? Paying it off offers a guaranteed return equal to the interest rate

• Are you saving for your children’s college? A 529 plan offers tax-advantaged growth for education expenses

• Are you planning a major purchase, such as a home? Building cash reserves may be a higher priority

• Is your emergency fund fully funded, typically three to six months of living expenses in a liquid account?

If the answer to any of these is yes, directing additional funds there may be a higher priority than investing in taxable accounts.

Investment Options After Maxing Out Retirement Accounts

If you have addressed the above priorities and still have additional funds to invest, here are the strongest options to consider:

Taxable Brokerage Account

A taxable brokerage account gives you access to the same investments available in an IRA, stocks, bonds, ETFs, mutual funds, and more, without the contribution limits or early withdrawal restrictions of retirement accounts. The trade-off is that you will owe taxes on dividends, interest, and capital gains as they are realized.

To minimize the tax drag in a taxable account, consider the following strategies:

• Buy and hold — long-term capital gains are taxed at 0%, 15%, or 20%, depending on your income level, significantly lower than ordinary income tax rates that apply to short-term gains

• Index funds and ETFs — passively managed funds generate fewer taxable events than actively managed funds, making them more tax-efficient in a taxable account

• Tax-loss harvesting — strategically selling investments at a loss to offset capital gains can reduce your annual tax liability

Bond Funds and Tax-Free Municipal Bonds

Bond funds expose your portfolio to a different type of investment with generally lower volatility than stocks. Tax-free municipal bonds offer an especially compelling option in a taxable account: the interest income is exempt from federal income tax and, in many cases, state and local taxes as well. Depending on your tax bracket, the effective yield on municipal bonds can exceed that of comparable taxable bonds.

I Bonds

Series I Savings Bonds offer inflation-indexed returns backed by the US government. The current composite rate for I Bonds issued May through October 2026 is 4.26%. I Bonds can be purchased for up to $10,000 per person per year through TreasuryDirect.gov and offer both federal tax deferral and state and local tax exemption on interest. They are particularly useful as an inflation-protected component of an emergency fund or conservative savings allocation.

Real Estate

Real estate investments can provide a steady income stream and long-term appreciation. Direct real estate ownership also offers tax advantages such as depreciation deductions and the ability to defer capital gains through a 1031 exchange when buying and selling properties.

For investors who do not want the responsibility of managing physical property, Real Estate Investment Trusts (REITs) offer a way to access real estate returns through publicly traded securities, with no landlord responsibilities required.

529 College Savings Plan

If you have children and expect to pay for college, a 529 plan offers tax-advantaged growth for education expenses. Contributions are made with after-tax dollars, but earnings grow tax-free, and qualified withdrawals for education expenses are not taxed. Many states also offer a state income tax deduction for contributions.

Military-Specific Investment Options Beyond Retirement Account Limits

Military members have several additional options worth considering when investing beyond standard retirement account limits:

Savings Deposit Program (SDP) — deployed military members can deposit up to $10,000 in the SDP and earn a guaranteed 10% annual return while deployed to a combat zone. This is one of the highest guaranteed returns available anywhere and should be maximized before any other investment option during deployment.

Tax-free combat zone contributions — military members deployed to a combat zone can contribute tax-free pay to a Roth TSP, creating a situation where contributions are never taxed, either going in or coming out. This is a unique opportunity not available to civilian investors.

Blended Retirement System matching — if you are not yet capturing the full 5% government match in your TSP, do that before investing in any taxable account.

The Right Order of Operations for Investing Beyond Your Retirement Accounts

Maxing out your 401(k) or TSP and IRA is an excellent foundation for retirement, but for those who can save beyond these limits, there are strong options available. The HSA is the most tax-efficient next step for eligible investors, followed by taxable brokerage accounts with tax-efficient investment strategies, municipal bonds, I Bonds, and real estate.

For military members, the Savings Deposit Program during deployment and tax-free combat zone TSP contributions offer additional opportunities that no civilian investor can match. Taking full advantage of these military-specific tools before moving to taxable investments is almost always the right order of operations.
