The Tax Bite: When Inflation Pushes You into a Higher Bracket

Taxes are another area where inflation can have a hidden and unhelpful effect on your finances. You might think that once you’re retired, your tax situation becomes simpler. In many ways it does, but inflation can introduce a couple of tricky complications.

One of these is a concept called “bracket creep.” The U.S. tax system is progressive, meaning you pay a higher tax rate on higher levels of income. These income levels are organized into tax brackets. The government, through the Internal Revenue Service (IRS), usually adjusts these brackets for inflation each year. However, these adjustments don’t always perfectly align with your personal situation.

The real issue for many retirees arises from their withdrawal strategies. When inflation is high, you need to pull more money out of your retirement accounts—like your traditional IRA or 401(k)—just to cover the same expenses. Every dollar you withdraw from these accounts is generally counted as taxable income.

Let’s say you normally withdraw $40,000 a year from your IRA. To cope with a period of high inflation, you might find you now need to withdraw $45,000. That extra $5,000 in income could be enough to push you over the threshold into a higher tax bracket. This means a larger portion of your income is now being taxed at a higher rate, leaving you with less money in your pocket, even though your actual lifestyle hasn’t changed.

Inflation can also impact whether or not your Social Security benefits are taxed. Whether you pay federal income tax on your benefits depends on your “combined income.” This is calculated by taking your adjusted gross income, adding any non-taxable interest, and then adding one-half of your Social Security benefits for the year.

There are specific income thresholds. If your combined income is above a certain amount, a portion of your benefits becomes taxable. When you have to withdraw more from your IRA or other retirement accounts due to inflation, it increases your combined income. This can cause you to cross the threshold, meaning you suddenly have to start paying taxes on your Social Security benefits when you didn’t before. Or, if you were already paying taxes on a portion, an even larger portion may become taxable.

This is a particularly sneaky effect because you’re not actually any “richer”—you’re just withdrawing more money to keep up. But from a tax perspective, your income has risen, and so has your potential tax bill.
