Social Security Is Taxable? How to Minimize Taxes (2024)

Generally, your Social Security benefits are taxed when your income is more than $25,000 per year, including income from investments held in retirement accounts like traditional 401(k)s and IRAs. If Social Security is your only source of income, you likely won't pay any tax on those payments. However, if you're receiving income from investments, a part-time job, or other sources, there's a good chance you’ll have to pay taxes on your Social Security income.

Regardless of your total income, the maximum taxable portion of your Social Security benefits won't exceed 85% under the current tax codes.

If your benefits are indeed subject to taxation, consider these three strategies to potentially reduce the tax implications:

• Convert a traditional 401(k)/IRA to a Roth 401(k)/IRA
• Leverage investments that provide nontaxable income
• Delay taking Social Security benefits

Let's look at how to determine if your Social Security income will be taxed, plus a few ideas that might help reduce your taxable income in retirement.

To calculate your taxable Social Security benefit, first determine your adjusted gross income (AGI), which is your total taxable income. This might include money you make from:

• Employment
• Distributions from traditional 401(k) plans and traditional IRAs
• Taxable income from investments, such as stock dividends and interest from taxable accounts

Second, subtract any tax deductions to determine your AGI.

Finally, add two components to that AGI:

• You nontaxable interest
• Half the amount of your Social Security benefit

This total is your "combined income." If your combined income is more than $34,000 for singles or $44,000 for couples, up to 85% of your Social Security income may be taxed.

Withdrawals on Roth IRAs and Roth 401(k)s aren't subject to taxation because taxes were taken when the contributions were made. If your money is in a traditional IRA or 401(k), you already received a tax advantage in the form of an income tax deduction when you deposited the money, so 100% of those withdrawals will be taxed as income. Income from a Roth account doesn't count toward the "combined income" that will affect taxes on your Social Security benefits. But remember, you must have a Roth account open for five years and be over the age of 59.5 before you can withdraw the money tax-free. You can open a Roth at any time, and you can continue to contribute to a Roth in retirement as long as you have earned income. (Income must be from employment or self-employment wages. Income from investments or Social Security don't qualify as income for the purposes of contributing to an IRA.)

Be aware that converting from a tax-deferred retirement account to a Roth IRA means you’ll pay income tax on that money, which can be substantial, but after that first tax bill, your distributions will be tax free and won't count toward your income calculation. Also, a provision in the Tax Cut and Jobs Act declared that a Roth conversion can't be "recharacterized," which means it can’t be transferred back to a traditional IRA if you change your mind about the conversion.

Some investments generate taxable income, while others are nontaxable. For example, the interest income from many bonds is subject to tax. Dividends and interest from savings accounts or other investments also count as taxable income. Interest income on municipal bonds generally is exempt from federal and state income taxes with a few exceptions: Any capital gains distributed may be taxable; income received from muni investments may be subject to the Alternative Minimum Tax for some investors; and interest income from muni bonds is added back as part of your modified adjusted gross income when computing potential tax due on Social Security benefits on modified income of more than $25,000 for individual filers, $32,000 for joint filers.

With a strategy of reallocating investments to include nontaxable income, investors can accept retirement payments that do not count as income, which means they won't add to the income that can trigger taxes on Social Security benefits. By shifting some of your assets to those that favor the types of income that are shielded from taxation, you can still plan for the same amount of retirement income with potentially lower taxes on your Social Security.

If you have outside income and other investments, consider being more aggressive on drawing down those assets early on while delaying taking Social Security. You’ll get a Social Security bump the longer you wait—8% per year until age 70. By then, if you've drawn down other assets (which are likely taxed at a higher rate), there might be fewer of those assets left to tax, which can potentially lower the amount of your Social Security benefits subject to taxation.

Before choosing to delay your Social Security benefits, assess your expected income from all sources and compare them to your expected expenses. This can help ensure you'll have the funds to live comfortably.
