How Could Inflation Affect Your Taxes?

The cost of living as measured by the Consumer Price Index (CPI) was up ​7 percent​ year-to-year in December, the largest increase since 1982, with no end in sight.

Inflation reduces your purchasing power, meaning you'll spend more for groceries and gas and just about everything else it takes to cover your living expenses. To make matters worse, it'll also affect how much you pay in taxes.

There are various ways that a higher inflation rate will affect your tax bill.

Despite the rapid rise in housing prices and related property taxes, the cap on the deduction for state and local taxes remains at ​$10,000​.

The federal tax code has seven income tax brackets, with each one taking a higher percentage of your income. As you earn more, you pay a higher percentage of your income, up to a maximum of ​37 percent.​ The fear is that if you receive a raise, it may be wiped out by moving you into a higher tax rate bracket.

Fortunately, the IRS increases the dollar amount of the tax brackets each year in addition to adjustments to the standard deduction and personal exemptions to account for inflation. This reduce the effect of changing tax brackets on your federal income tax.

However, this isn't true of many states. According to the Tax Foundation, 13 states and Washington D.C. don't adjust their tax brackets for inflation. Plus, ​10 states​ don't change their standard deduction, and 18 states don't index their personal exemption.

Homeowners are entitled to a capital gains exemption of ​$250,000​ for single taxpayers and ​$500,000​ for married couples if they meet certain requirements and purchase another home.

However, these amounts have not been adjusted since 1997 to reflect the effects of inflation. If they had been indexed to inflation, these exemptions would now be over ​$400,000​ for single taxpayers and over ​$800,000​ for couples.

Despite the rapid rise in housing prices and related property taxes, the cap on the deduction for state and local taxes remains at ​$10,000​. Taxes in excess of this amount will not be deductible on your federal tax return.

In its efforts to reduce inflation, the Federal Reserve Bank will gradually increase the federal funds rate. As a result, mortgage interest rates will rise, and homeowners will be paying more in interest. In addition, home prices have shot up dramatically in the past year. This means homeowners will be paying more in interest as they purchase higher-priced homes.

Unfortunately, the IRS has a cap of ​$750,000​ on the amount of mortgage debt when it comes to deducting interest. If your mortgage is higher than this amount, you won't be able to deduct the excess mortgage interest.

The Social Security Administration adjusts its benefits each year for inflation. However, it hasn't adjusted the income level at which you start paying taxes on ​85 percent​ of your Social Security payments. That amount has remained at ​$34,000​ for single filers and ​$44,000​ for married filing jointly since 1994. If this income threshold had been adjusted for inflation, it would be over $60,000 in 2022 for single filers, and more than ​$80,000​ for couples, according to Fox Business.

The threshold incomes that trigger the 3.8 percent surcharge on net investment income put in place by Obama in 2013 have not changed. Single taxpayers with adjusted gross incomes above ​$200,000​ and couples with adjusted gross incomes above ​$250,000​ will pay this surcharge on their net investment income above these thresholds.

If these threshold incomes had been adjusted for the impact of inflation, the surcharge could have been reduced or possibly eliminated.

Now for some good news. The amount you can deduct to add to your 401(k) has been adjusted as inflation rises. The tax-deductible amount that taxpayers under age 50 can contribute to their 401(k) has been increased from ​$19,500 to $20,500​ in 2021. This is roughly a 5 percent increase.
