A retirement contribution election can look settled in January while quietly putting the wrong amount into each paycheck. Perhaps last year's dollar election carried forward. Perhaps you changed employers. Or perhaps a birthday changes the catch-up contribution available to you this year.

The useful starting point is to match three things: the limit that applies to your account, the contributions you have already made and the paychecks still available. Then check how the election affects take-home pay. A larger legal limit creates room to save; it does not establish what your household can comfortably contribute.

Match the limit to the account

For 2026, the basic employee deferral limit for a 401(k) is $24,500. An eligible participant age 50 or older can generally make an additional $8,000 catch-up contribution if the plan permits it. For someone attaining age 60, 61, 62 or 63 during 2026, the higher catch-up limit is $11,250 instead. That higher amount replaces the ordinary catch-up; it is not added on top of it. [1]

Those figures concern employee deferrals. Employer contributions are subject to other limits and plan provisions. A company contribution does not use your $24,500 personal deferral allowance, but that does not mean total contributions are unlimited. Your administrator should confirm which amounts count toward each applicable limit. [1][2]

An IRA has a separate limit. For 2026, the combined annual contribution limit across traditional and Roth IRAs is $7,500, plus a $1,100 catch-up for an eligible person age 50 or older. Compensation, income and other eligibility requirements still matter. Being permitted to contribute to a traditional IRA does not automatically make that contribution deductible. [1][3]

Translate the annual goal into payroll

Sonia is a hypothetical employee who turns 62 during 2026. Her employer's 401(k) permits the higher catch-up, her eligible compensation supports the contribution and no other plan restrictions reduce it. She wants to contribute the maximum $35,750 over 26 paychecks.

That means $1,375 per paycheck: $35,750 divided by 26. Sonia checks whether payroll accepts a dollar election or requires a percentage, and whether bonuses receive the same treatment. A percentage that works with regular salary can produce a different result when a bonus arrives or hours change.

Suppose Sonia's qualifying 2025 wages from the employer exceeded $150,000. Her 2026 catch-up contributions generally must be Roth contributions under the applicable rule. That requirement concerns the catch-up portion, not automatically every dollar she saves. Her ordinary deferrals can still follow the choices available under her plan. [1][4]

Sonia therefore checks both the amount deducted and its source designation. Reaching the annual total with the wrong pretax and Roth split is not the same as getting the election right. The Roth portion also changes the current tax effect, so she reviews net pay alongside scheduled household bills before committing to the full annual amount.

If she makes the change after several payrolls have run, dividing by 26 is no longer the right calculation. She needs the remaining contribution goal divided by the remaining eligible paychecks. Contributions already made count, even if the election has just changed.

Bring prior employment into the calculation

A second hypothetical employee, Marcus, is 45 and changes jobs during the year. He contributes $16,000 to his former employer's 401(k) and elects another $12,000 at the new employer. Neither payroll system necessarily sees the other employer's deductions.

His combined $28,000 would exceed the $24,500 basic personal limit by $3,500, assuming no special exception. Changing employers does not reset that limit. Generally, employee deferrals to 401(k) and 403(b) arrangements must be coordinated for this purpose. A governmental 457(b) has a separate limit framework, so avoid simply adding every account with “retirement” in its name to one calculation. [1][2]

Marcus should retain the former plan’s final contribution record and give the new administrator the relevant year-to-date information before the next election is processed. If an excess has already occurred, he should promptly ask the administrators and tax professional about the applicable correction process. Moving money out himself is not a substitute for a properly handled correction.

The practical lesson is to keep a personal contribution record when employment changes. The record should distinguish your salary deferrals, employer contributions and any transfers between accounts. A rollover is not a new salary deferral.

Check the match before accelerating contributions

Some people prefer to finish contributing early in the year. Others spread contributions across each paycheck. The better choice can depend partly on how the employer match works.

Ask whether matching contributions are calculated each payroll and whether the plan provides a year-end reconciliation, often called a true-up. Front-loading contributions can affect the match if later paychecks contain no employee deferrals and the plan does not restore the difference. Read the actual formula rather than assuming all plans operate alike. [2]

Also consider cash reserves, debt payments and near-term expenses. Saving the maximum while repeatedly borrowing to cover normal bills can create a different financial problem. A sustainable election that earns an available match may be a more useful starting point than an annual maximum chosen without a cash-flow review.

Set a date to inspect the next pay statement and retirement account posting. Confirm the dollar amount, pretax or Roth treatment, employer match and year-to-date totals. Then repeat the review after a job change, significant bonus or revised savings goal. January's election should remain connected to the year you actually experience.
