The IRS must be calculating inflation differently than the Social Security Administration.
The IRS increased its tax brackets by about 5.4% for tax filers for 2024, including for those filing as married couples or those filing separately. The IRS adjusts tax brackets each year to adjust for inflation.
At the same time, the Social Security Administration has calculated increases to its 71 million recipients at 3.2% to keep up with inflation.
There’s no real explanation about why the government would determine inflation differently, depending on the agency.
