2026 shared employee limit

The selection loads the general 2026 IRS catch-up amount. Confirm how catch-up rules apply to your plans.

Amount in US dollars.

The general 2026 401(k)/403(b) elective-deferral limit is $24,500.

Amount in US dollars.

2026: generally $8,000 at age 50+, or $11,250 at ages 60-63. Enter zero when no catch-up applies.

Amount in US dollars. Unit: YTD.

Add your pre-tax and Roth employee deferrals from every prior and current modeled employer this calendar year. Do not add employer match.

Enter actual payroll totals. A prior employer generally does not know what you defer at a new employer.

Job / plan 1

Unit: checks.

Include only checks on which you can change this plan's employee contribution.

Amount in US dollars. Unit: /check.

Use compensation eligible for this plan's match, not take-home pay.

Value in percent.

Use the highest percentage payroll will accept, including any per-check cap.

Employer match formula

Value in percent.

Example: enter 50 for $0.50 per $1 contributed.

Value in percent.

Example: enter 6 for a match that stops after 6% of pay.

Under this simplified formula, $1,680 of employee deferrals would target up to $1,680 of employer match across the entered remaining payroll.

Job / plan 2

Unit: checks.

Include only checks on which you can change this plan's employee contribution.

Amount in US dollars. Unit: /check.

Use compensation eligible for this plan's match, not take-home pay.

Value in percent.

Use the highest percentage payroll will accept, including any per-check cap.

Employer match formula

Value in percent.

Example: enter 50 for $0.50 per $1 contributed.

Value in percent.

Example: enter 6 for a match that stops after 6% of pay.

Under this simplified formula, $1,536 of employee deferrals would target up to $768 of employer match across the entered remaining payroll.

The entered room can capture the modeled matches

The allocation recommends $6,000 of additional employee deferrals and estimates $2,448 of employer match. Verify payroll election deadlines and each plan document before changing contributions.

Items to verify

  • Job / plan 2 is marked as having a true-up. Verify the plan's eligible-compensation period, allocation date, and any employment requirement; the model does not assume one employer will true up another employer's match.

Calculation scope

How this calculator works

The engine subtracts entered year-to-date employee deferrals from the entered annual limit. It creates one match layer for each active plan and funds the layer with the greatest employer match per employee dollar first. It never recommends more than the remaining shared room, remaining compensation, or the entered payroll percentage cap.

Once the modeled match layers are filled, any extra employee deferral room is spread across the plans in proportion to their remaining payroll capacity. The displayed percentage is an even rate across the entered remaining paychecks; payroll rounding can make the final check differ.

Across the active plans, the entered formulas require $3,216 of employee deferrals to target $2,448 of employer match before considering payroll caps.

  • The shared employee limit is applied to the entered pre-tax and Roth elective deferrals across the modeled unrelated-employer 401(k) or 403(b) plans. Employer contributions and rollovers are not included in that employee limit.
  • Each remaining paycheck is assumed to have the same eligible gross compensation, and the recommended percentage is assumed to apply to every remaining paycheck.
  • The employer match is simplified to the entered percentage of employee deferrals up to the entered percentage of compensation. Tiered, fixed-dollar, discretionary, profit-sharing, and student-loan-payment matches are not modeled.
  • The optimizer funds the highest employer match earned per employee dollar first. Extra deferral room after all available match layers is spread in proportion to the plans’ remaining payroll contribution capacity.
  • A true-up changes when a match may be reconciled, not the cross-employer employee deferral limit. Plan documents control eligible compensation, timing, vesting, and employment conditions.
  • SIMPLE plans, SARSEPs, governmental 457(b) plans, related employers, controlled businesses, required Roth catch-up treatment, annual-additions limits, compensation caps, nondiscrimination refunds, and payroll rounding are outside this model.

How to coordinate 401(k) contributions across two jobs

Changing employers does not restart the calendar-year employee elective-deferral limit. A second payroll may stop only at its own records, so workers often have to coordinate the combined amount themselves.

This calculator puts both remaining payrolls and match formulas in one place, then directs scarce employee deferral dollars toward the strongest available match first.

How to use this tool

  1. Add every employee deferral

    Combine year-to-date pre-tax and Roth elective deferrals from old and current payroll records. Leave employer matching dollars out.

  2. Copy each match formula

    Use each Summary Plan Description or benefits portal for the match rate, compensation threshold, payroll cap, and true-up terms.

  3. Enter only remaining payroll

    Count checks on which a new election can take effect and use gross compensation that is eligible for the match.

  4. Verify the suggested percentages

    Check enrollment deadlines, percentage increments, bonus treatment, final-paycheck rules, and whether an annual true-up has conditions.

Why the limit follows the worker

The basic elective-deferral limit generally aggregates employee deferrals across the applicable plans in which a person participates. An old and a new unrelated employer may each know only the amounts processed through its own payroll.

How match-first allocation works

  • A 100% match earns more per employee dollar than a 50% match.
  • Each match layer stops at its entered compensation threshold.
  • The recommendation respects each plan’s entered payroll percentage cap.
  • Extra savings above the match layers are spread across remaining payroll capacity.
  • Employer match does not consume the employee elective-deferral limit shown here.

What a true-up can change

Some plans calculate match every paycheck and later reconcile it using a broader compensation period. A true-up can reduce the risk of missing that employer’s match after uneven contributions, but plan documents may impose allocation dates, eligible-compensation definitions, or an employment requirement.

Records worth gathering

  • Year-to-date pay statements from every employer
  • Pre-tax and Roth employee deferral totals
  • Remaining payroll calendar and election effective date
  • Summary Plan Description and match notice
  • True-up, bonus-pay, and final-paycheck provisions

This planning tool does not determine catch-up eligibility or required Roth catch-up treatment, plan eligibility, vesting, annual-additions limits, related-employer treatment, or how to correct an excess deferral. It does not model SIMPLE plans, SARSEPs, governmental 457(b) plans, tiered matches, or self-employed employer contributions. Plan documents and official guidance control.

Frequently asked questions

Can I contribute the full employee limit at both jobs?

Generally no for the standard 401(k) and 403(b) elective deferrals modeled here. The calendar-year employee limit is combined across the applicable plans, even when the employers are unrelated.

Do pre-tax and Roth 401(k) contributions share the limit?

Yes. Pre-tax and designated Roth employee elective deferrals generally count together toward the employee limit. Employer matching contributions are not added to that employee limit.

Which employer match should I fund first?

When employee deferral room is scarce, start with the match that earns the greatest employer contribution per employee dollar, then fund the next match layer. Other factors such as vesting, fees, investment choices, and job tenure can still matter.

What does a 401(k) true-up do?

A true-up is a plan-specific reconciliation that may add match when paycheck-by-paycheck deposits did not produce the match described for a broader period. It does not make one employer responsible for match at another employer.

What if I already entered more than the combined limit?

The calculator stops recommending additional employee deferrals and displays the entered difference. Compare payroll records and contact the applicable plan administrators promptly for plan-specific guidance; this tool does not select or carry out a correction.

Does a governmental 457(b) contribution share this limit?

Governmental 457(b) plans can follow a separate elective-deferral framework. This calculator intentionally excludes them because mixing plan types can change the analysis.
