11 numbers to know in 2024 — starting with FSAs, 401(k)s

According to recent figures released by the Internal Revenue Service, limits on out-of-pocket expenses and contributions to flexible spending accounts, 401(k)s, health savings accounts and high-deductible health plans will increase in 2024.

These increases come as the inflation rate remains stubbornly high at 3.2% in October. And economists say this rate is not likely to fall to the Fed’s long-term target of 2% in 2024. Contribution limits to health savings accounts, for example, are adjusted for inflation by the IRS. The changes are slated to take effect Jan. 1.

Employees can save money on their income tax bills with larger contributions to their 401(k), HSAs and FSAs, improving their own financial picture, notes Julie Stich, vice president of content at the International Foundation of Employee Benefit Plans.

“If you encourage employees to take advantage of 401(k)s, FSAs and HSAs, it helps employees with their financial wellness, which employers care about,” Stich says.

As HR leaders plan for 2024, here is a look at how contribution and out-of-pocket expense limits are shaping up for the new year.
