What you can contribute to a 401(k) and Roth IRA in 2026
The first step is separating employee contributions from employer money. In 2026, you can defer up to $24,500 from your pay into a standard 401(k), 403(b), governmental 457(b), or federal Thrift Savings Plan. That limit covers your combined traditional and Roth 401(k) salary deferrals across plans maintained by the same employer. Your employer match does not use up the $24,500 employee limit, but it does count toward the larger annual additions limit.
| Account or contribution type | 2026 limit | Who can use it |
|---|---|---|
| 401(k) employee deferrals | $24,500 | Employees, limited by compensation and plan rules |
| 401(k) catch-up contribution | $8,000 | Most participants age 50 or older |
| 401(k) age 60–63 catch-up | $11,250 | Eligible participants who turn 60, 61, 62, or 63 in 2026 |
| Traditional and Roth IRA total | $7,500 | Combined limit across all IRAs |
| IRA catch-up contribution | $1,100 | Individuals age 50 or older |
| 401(k) annual additions | $72,000 | Employee and employer contributions combined, subject to plan rules |
The IRA limit is shared. You cannot put $7,500 into a Roth IRA and another $7,500 into a traditional IRA. You can split the money, but the total remains $7,500, or $8,600 after the IRA catch-up contribution if you are at least 50 by the end of the year. The IRS lists the official 2026 retirement plan limits and updates the figures when rules change.
The contribution order that works for most households
My default recommendation is match first, Roth IRA second, and the 401(k) third. Start by contributing enough to receive every dollar of your employer match, because declining that match creates an immediate and avoidable loss; then fund a Roth IRA up to $7,500 if your income allows it, since an IRA often offers a wider investment menu and easier control over costs; after that, raise payroll deferrals until you reach the $24,500 401(k) limit.
That order changes when you carry credit-card debt at a high interest rate, lack a basic emergency reserve, or sit in a high current tax bracket and have a strong traditional 401(k) plan. In those cases, capture the match, stabilize cash flow, and direct more money to the traditional 401(k) before forcing the Roth IRA to the front of the line.
The clear winner for a worker with a full match, manageable debt, a cash reserve, and moderate taxable income is the match-plus-Roth-plus-401(k) sequence. It combines free employer money, tax diversification, and a large workplace contribution without making the plan depend on one future tax rate.
How to reach the $24,500 401(k) limit through payroll
Most people do not fail to max out because they lack discipline. They fail because they wait until December, use a flat dollar amount that ignores pay frequency, or forget that a job change can create two 401(k) accounts with one shared employee limit. Payroll planning removes those problems before they become expensive.
Convert the annual goal into a paycheck amount
For a worker under age 50, $24,500 divided across 26 biweekly paychecks equals about $942.31 per paycheck. Across 24 semimonthly paychecks, the amount is about $1,020.83. A monthly payroll schedule requires roughly $2,041.67. These figures are contribution targets, not percentages, so divide the target by eligible annual salary to estimate the payroll percentage. A $100,000 salary would require a 24.5% deferral before considering the employer match.
Someone age 50 or older can target $32,500 in total employee deferrals: $24,500 plus the $8,000 catch-up amount. A participant who turns 60 through 63 during 2026 may have a total target of $35,750 because the higher catch-up limit is $11,250. The plan must allow the catch-up feature, so check the Summary Plan Description or benefits portal before setting the election.
Adjust after raises, bonuses, and job changes
Set the percentage early, then review it after every raise. A percentage election increases savings as pay rises, while a fixed dollar election can fall behind. If you change employers, add your employee deferrals from both plans together. The IRS $24,500 limit follows you across plans sponsored by unrelated employers, and an excess contribution may create tax and correction work.
High earners should also check the new Roth catch-up rule. For 2026, catch-up contributions generally must be designated Roth contributions for participants whose prior-year wages from the plan sponsor exceeded $150,000, if the plan has a Roth feature. Ask payroll how the rule is being applied before assuming every deferral will remain pre-tax.
How to fund a Roth IRA without an eligibility mistake
A Roth IRA is not automatically available at the full $7,500 amount. Your contribution room depends on taxable compensation and modified adjusted gross income, not simply on the amount shown in one paycheck. A workplace 401(k) does not prevent you from contributing to an IRA, but income can reduce or eliminate a direct Roth contribution.
- Estimate modified adjusted gross income. Use a current pay estimate, expected bonus, business income, and other taxable income. Do not rely only on last year’s income if your compensation changed.
- Check the 2026 Roth phase-out. For single filers and heads of household, the phase-out range is $153,000 to $168,000. For married couples filing jointly, it is $242,000 to $252,000. Married filing separately has a separate $0 to $10,000 range when the filer lived with a spouse during the year.
- Fund the account gradually. A full $7,500 target equals $625 per month or about $288.46 per biweekly pay period. Automating the transfer is useful, but verify the annual total after changing banks, jobs, or contribution amounts.
- Use the backdoor Roth process only after checking the tax details. A person above the direct Roth income range may make a nondeductible traditional IRA contribution and then convert it, but the pro-rata rule considers pre-tax balances in traditional, rollover, SEP, and SIMPLE IRAs. A tax professional can confirm the correct reporting before you act.
- Watch for excess contributions. The IRS warns that excess Roth IRA contributions can trigger a 6% excise tax. Correcting an excess promptly is cheaper and cleaner than discovering it during a later tax review.
For direct Roth eligibility, the clear decision is simple: contribute the full amount only after checking your projected income. The IRS IRA contribution guidance explains the shared IRA limit and the income rules.
Traditional 401(k) or Roth 401(k): which tax choice wins?
Choose the traditional 401(k) as the default when your current marginal tax rate is high and the deduction has real value. Each pre-tax contribution reduces current taxable income, although it does not reduce every payroll tax. That deduction can matter when you are in your peak earning years, face a large tax bill, or want to keep more cash available while still saving aggressively.
Choose the Roth 401(k) when you are in a lower tax bracket, expect higher taxable income later, or want tax-free qualified retirement withdrawals from a designated Roth account. Roth 401(k) contributions do not reduce current taxable income, so the tradeoff is immediate tax cost in exchange for future tax diversification. You can split the $24,500 employee limit between traditional and Roth 401(k) contributions, but the combined total cannot exceed the annual limit.
The strongest practical combination for many savers is a traditional 401(k) plus a Roth IRA. The traditional account provides a current deduction, while the Roth IRA creates a separate tax treatment. A Roth 401(k) becomes more attractive when the workplace plan has low-cost investments and your current tax rate is unusually low.
Do not choose based on the label alone. Compare your federal and state tax brackets, expected retirement income, employer plan fees, investment choices, and need for current cash. The correct answer is a deliberate tax mix, not an automatic belief that every dollar should be pre-tax or Roth.
Questions that cause expensive contribution mistakes
Can employer matching push me over the $24,500 limit?
Employer matching usually does not count toward the $24,500 employee elective-deferral limit. It does count toward the broader defined-contribution annual additions limit, which is $72,000 in 2026 for most plans, subject to compensation and plan rules. Your benefits department can explain how matching, profit sharing, and after-tax contributions are treated inside your specific plan.
Can I max out two 401(k) plans?
You may participate in two plans, but your employee deferrals generally share one annual limit. If you contribute $15,000 to one employer’s plan and change jobs, you have about $9,500 of employee deferral room left for the year. Tell the new plan administrator about earlier contributions so your elections do not overshoot the limit.
What if I contribute too much to my Roth IRA?
Contact the IRA custodian and tax professional quickly. An excess contribution may need to be removed with associated earnings before the applicable correction deadline. Leaving the excess in place can create a recurring excise tax, and the paperwork must match the correction.
Does a 401(k) loan help me reach the maximum?
No. A loan is not a new contribution and does not create extra tax-advantaged room. It can also reduce payroll flexibility and expose retirement savings to repayment risk after a job change. Use a loan only after reviewing the plan terms and the consequences of missed payments.
Should I stop contributing after reaching the limit?
Once employee deferrals reach the applicable limit, stop salary deferrals unless the plan has another permitted contribution type and you understand the annual additions cap. Redirect new savings to an eligible IRA, health savings account, or taxable account based on your goals. Never keep payroll deductions running simply because the election was set months earlier.
When maxing out is the wrong move
Maxing out retirement accounts is a strong target, not a command that overrides every other financial need. A worker with no emergency reserve may need accessible cash before increasing a 401(k) from 10% to 25%. Someone carrying high-interest revolving debt can often improve their balance sheet faster by paying that debt after capturing the employer match. A household facing unstable income, overdue taxes, or essential medical costs also needs liquidity before an aggressive retirement target.
The account itself can be excellent while the timing is wrong. Do not sacrifice rent, insurance, minimum debt payments, or a cash reserve to hit a round annual number. Do not assume an IRA is superior if the workplace plan offers unusually low-cost investments, a valuable match, or a strong Roth conversion feature. Account providers such as Fidelity, Vanguard, and Charles Schwab can all offer retirement accounts, but the provider name does not fix an unsuitable contribution plan or poor investment selection.
My final recommendation is specific: capture the full employer match, keep a cash reserve, eliminate high-interest debt, then target $7,500 in a Roth IRA when eligible and raise 401(k) deferrals toward $24,500. If you are age 50 or older, add the applicable catch-up amount. Recheck income eligibility, payroll totals, and plan rules before year-end so the strategy reaches the limit without creating an excess contribution problem.
