The Internal Revenue Service (IRS) announced inflation adjustments for many tax provisions in 2024, including higher contribution limits for various types of accounts and updated tax brackets.

Retirement account contribution limits

The IRS increased contribution limits for individual retirement accounts (IRAs), as well as 401(k), 403(b), and most 457 plans.

The maximum amount a worker can contribute to 401(k)/403(b)/457 plans is $23,000 in 2024, an increase of $500. The IRA contribution limit also increased $500 to $7,000. Catch-up contribution limits remain unchanged in 2024.

HSA & FSA contribution limits

The amount workers can contribute to medical savings accounts will also increase in 2024.

Individuals enrolled in a high deductible health plan (HDHP) with a health savings account (HSA) will be able to contribute up to $4,150 and those with family coverage will be able to save a maximum of $8,300.

For workers who don’t have an HDHP with an HSA and instead use a flexible spending account (FSA), the maximum contribution for 2024 is $3,200. For plans that allow unused balances to roll over, the maximum amount that can be rolled over will increase to $640.
