401(k) Contribution Limits 2026
The IRS sets three separate 401(k) limits, and they all move most years. Here are the 2026 numbers, who the catch-up is for, and how to hit the max without breaking your budget.
For 2026, employees can contribute up to the IRS elective deferral limit, workers 50 and older add a catch-up amount, and total contributions including the match face a higher cap. Check current IRS figures each year, since limits adjust with inflation.
The three limits
The employee elective deferral limit caps what you can contribute from your paycheck each year. The catch-up limit adds extra room for workers 50 and older. The total limit caps everything combined: your contributions, the employer match, and any after-tax contributions.
Because limits adjust with inflation, always verify the current year on IRS.gov before planning. Payroll systems usually stop your contributions automatically at the employee limit, but the total limit needs manual attention if you make after-tax contributions.
How to actually max it out
Divide the annual employee limit by your number of paychecks and set that as your per-paycheck contribution. On 26 biweekly paychecks, the max divides evenly into a fixed dollar amount per check.
Watch the per-paycheck match trap: if you hit the max in October, November and December paychecks contribute nothing and may earn no match. Some plans true up at year end; many do not. Even pacing avoids the problem entirely.
What if you cannot max it out
Most people cannot, and the priority order still works: full match first, then Roth IRA or HSA, then more 401(k). Someone contributing 10 percent with a 4 percent match is already at 14 percent total, close to the 15 percent guideline.
Automate increases instead of relying on willpower. Many plans offer auto-escalation that raises your rate 1 point per year until a cap you choose. Pair that with directing half of every raise to the 401(k) and the max gets closer every year.

Contribution limit questions
What happens if I overcontribute to my 401(k)?
Excess deferrals withdrawn on time are taxed in the year contributed, which is the clean outcome. Miss the deadline and the excess is taxed again at withdrawal, a true double tax. This usually happens with two jobs in one year, since neither payroll knows about the other.
Does the employer match count toward the limit?
Your personal cap covers only your elective deferrals. The match sits on top of that, and both together must fit under the total annual additions limit. For most savers the total limit only binds when making after-tax contributions.
