What Is a 401k and How Does the Employer Match Work?
The 401(k) is the workplace retirement plan offered by many employers. You put part of your pay into the account before tax, or after tax in a Roth 401(k). Your money grows tax-deferred until you withdraw it. Many employers add their own money when you contribute. That extra money carries the name employer match. This article explains how the plan works, how the match works, and the 2026 IRS limits. It is educational. It is not personal financial advice.
How the plan works
The plan takes its name from section 401(k) of the US tax code. You choose the percentage of pay to contribute. Your employer takes it from your paycheck and deposits it in your account. You invest the money in funds your plan offers. Contributions lower your taxable income in a traditional plan. You pay tax when you withdraw the money in retirement. In a Roth 401(k), you contribute after-tax pay. Qualified withdrawals in retirement are tax-free. You can hold both types in the same plan. The IRS announced the 2026 limits in news release IR-2025-111 on November 13, 2025.
How does the employer match work?
With an employer match, your employer adds money to the plan when you contribute. It follows the amount you put in. One common formula: 50 percent of the first 6 percent of your pay. Worked example: you earn $60,000 a year. You contribute 6 percent of your pay. That comes to $3,600 a year. Your employer adds 50 cents for each dollar you put in, up to that 6 percent. That comes to $1,800 a year from your employer. Your account gets $5,400 a year in total. If you contribute less than 6 percent, you get less match. If you contribute 3 percent, or $1,800, your employer adds $900. You leave $900 of match on the table. To get the full match, contribute at least the percentage where the formula stops. Your plan Summary Plan Description states the exact formula. Every employer formula differs. Some match dollar for dollar up to a cap. Some use tiered formulas. The safe harbor basic match pays 100 percent of your first 3 percent of pay, plus 50 percent of your next 2 percent. Many plans use that standard formula.
Vesting: when the match becomes yours
Your own contributions are always yours. Employer matching money may vest over time. Vesting means the schedule that decides when employer money fully belongs to you. Some plans use cliff vesting. You own none of the match until one set date, often three years, then you own all of it. Others use graded vesting. You own growing shares each year, up to six years. Safe harbor matching contributions are 100 percent vested at all times. Check your plan vesting schedule before you change jobs. Leaving early can mean forfeiting unvested match money.
2026 contribution limits
| Limit | 2026 amount |
|---|---|
| Your own contributions (pre-tax and Roth combined) | $24,500 |
| Catch-up, age 50 and over | $8,000 more ($32,500 total) |
| Higher catch-up, ages 60 to 63 | $11,250 more ($35,750 total) |
| Everything into the account, employer money included | $72,000 |
| Pay that counts for contribution formulas | $360,000 |
The $24,500 limit applies per person, not per plan. If you have two jobs with two plans, the plans share one limit. The employer match does not count against your $24,500 limit. It counts only against the $72,000 total. You can contribute your full limit and still receive the full match. From 2026, if your wages from that employer in the previous year were above the IRS threshold of $150,000, your catch-up contributions must go to the Roth side of the plan.
Leaving a job: your options
Leaving a job does not end the account. You have options. You can leave the money in the old plan if the plan allows it. You can roll it into your new employer plan. You can roll it into an individual retirement account. You can also cash it out, but that usually triggers tax and penalties. Withdrawals before age 59 and a half generally face income tax plus the 10 percent additional tax, with some exceptions. Direct rollovers move the money without tax withholding. Check your plan rules and the IRS guidance before you decide. Some plans also allow loans and hardship withdrawals. Those rules vary by plan.
Before you enroll: short checklist
- Confirm the match formula in the Summary Plan Description.
- Contribute at least the percentage that earns the full match.
- Note the vesting schedule before changing jobs.
- Review the fund menu and fees each year.
Bottom line
The plan lets you save for retirement from your paycheck, with tax benefits. The employer match adds extra money tied to your own contributions. Contribute at least enough to get the full match. That comes first in most plans. For 2026, you can defer up to $24,500 of your own pay, plus catch-up amounts if you are 50 or older. Employer money does not count against that limit. Read your plan Summary Plan Description for the exact match formula and vesting schedule. Those two documents decide how much extra money you actually get.
