Some retirees will pay more taxes on Social Security benefits in 2027.
This tax surprise could occur courtesy of a large cost-of-living adjustment (COLA).
While COLAs occur when inflation is high, the threshold at which benefits are subject to tax is not indexed to inflation, so more people are taxed on benefits each year.
A recent study identified one single habit that doubled Americans’ retirement savings and moved retirement from dream, to reality. Read more here.
Retirees have a lot of things to spend their money on, from travel and spoiling the grandkids to covering the cost of medical care as they age.

Most Americans drastically underestimate how much they need to retire and overestimate how prepared they are. But data shows that people with one habit have more than double the savings of those who don’t.
Unfortunately, taxes may be among the expenses seniors have to cover as well. The IRS doesn’t necessarily stop taxing you just because you’re retired, and many seniors need to budget for both federal and state taxes.
This could become an issue, as a good number of retirees on Social Security potentially face a big surprise next year when their taxes end up higher than in the past. Here’s why retirees better be prepared for the IRS to potentially take a bigger cut of their Social Security benefits in the coming year.
Retirees could be on track for an unpleasant tax surprise
Retirees collecting Social Security benefits could end up surprised by their IRS bills in 2027 for a simple reason. Benefits are likely to see a significant increase due to the COLA, but the threshold at which taxes kick in is not going to change.
In 2027, Social Security retirees could be looking at the fourth-largest Social Security Cost of Living Adjustment in 36 years. While we won’t know the specifics of the COLA until October, there are plenty of estimates out already, with the Senior Citizens League anticipating that the raise could total 3.9%, while independent Social Security and Medicare policy analyst Mary Johnson is projecting the raise will be even higher at 4.2%.
While a big raise is good news, it also puts more seniors at risk of being taxed on their Social Security benefits for the first time or paying a larger amount of tax than they did in the past. That’s because the thresholds at which benefits become taxable are not indexed to inflation, and do not increase just because benefits go higher.

In the 1980s, lawmakers began charging tax on Social Security benefits for the first time to shore up the program’s finances (which were struggling). An additional layer of taxes was then added in reforms in the 1990s.
