IRS Contribution Limits

Understanding IRS contribution limits is important, especially when your goal is to contribute the maximum to your account. Even if you can’t do the max, consider increasing your contribution a little each year to potentially move closer to your retirement goals.

Current Deferral Limits1

Plan Contribution limit
457(b) Deferred Compensation Plan Up to 100 percent of your compensation, but no more than $18,500
403(b) Tax Sheltered Annuity Plan Up to 100 percent of your compensation, but no more than $18,500
401(k) Savings & Investment Plan Up to 100 percent of your compensation, but no more than $18,500

When participating in both the 457(b) and 401(k) (or 403(b)) plan, you may contribute $18,500 per year to each plan, for a total of $37,000. If you are participating in both the 401(k) and 403(b) plans, your total combined contribution amount cannot be higher than $18,500 (or $24,500 if using the Age 50 catch-up provision).
