| Boilerpipe Text | A contribution is the amount an employer and employees (including
self-employed
individuals) pay into a retirement plan.
Limits on contributions and benefits
There are limits to how much employers and employees can contribute to a plan (or IRA) each year. The plan must specifically state that contributions or benefits cannot exceed certain limits. The limits differ depending on the type of plan.
IRA contribution limits
401(k) and profit-sharing plan contribution limits
SEP contribution limits (including grandfathered SARSEPs)
SIMPLE IRA contribution limits
403(b) contribution limits
457(b) contribution limits
Defined benefit plan benefit limits
Catch-up contribution limits
Basic elective deferral limit
The basic limit on elective deferrals is
$24,500
in 2026, $23,500 in 2025, $23,000 in 2024 and $22,500 in 2023, or 100% of the employee's compensation, whichever is less. The elective deferral limit for SIMPLE plans is 100% of compensation or $17,000 in 2026, $16,500 in 2025, $16,000 in 2024, and $15,500 in 2023. Catch-up contributions may also be allowed if the employee is age 50 or older.
If the employee's total contributions
exceed the deferral limit
, the difference is included in the employee's gross income.
Time for depositing elective deferrals
Employers must deposit employee contributions to the retirement plan's trust or individual accounts as soon as they can reasonably be segregated from the employer's general assets. The Department of Labor provides a
7-business-day safe harbor rule
for employee contributions to plans with fewer than 100 participants.

correct
this mistake.
Employer contributions
Employer matching contributions.
If the
plan document
permits, the employer can make matching contributions for an employee who contributes elective deferrals (for example, 50 cents for each dollar deferred). Employer matching contributions can be discretionary (contributed in some years and not in others, depending on the company's decision) or mandatory, as in SIMPLE plans and Safe Harbor 401(k) plans.
Employer discretionary or non-elective contributions.
If the plan document permits, the employer can make contributions other than matching contributions for participants. These contributions are made on behalf of all employees who are plan participants, including participants who choose not to contribute elective deferrals.
Types of employee contributions
Salary reduction/
elective deferral
contributions
are pre-tax employee contributions that are a generally a percentage of the employee's compensation. Some plans permit the employee to contribute a specific dollar amount each pay period.
401(k), 403(b) or SIMPLE IRA plans
may permit elective deferral contributions.
Designated Roth contributions
are a type of elective contribution that, unlike pre-tax elective contributions, are currently includible in gross income but tax-free when distributed. 401(k), 403(b) and governmental 457(b) plans can allow them. If a plan permits designated Roth contributions, it must also offer pre-tax elective deferral contributions.
After-tax contributions
are contributions from compensation (other than Roth contributions) that an employee must include in income on his or her tax return. If a plan allows after-tax contributions, they are not excluded from income and an employee cannot deduct them on his or her tax return.
Catch-up contributions
if permitted by a 401(k), 403(b), governmental 457(b), SARSEP or SIMPLE IRA plan, participants who are age 50 or over at the end of the calendar year can also make catch-up elective deferral contributions beyond the basic limit on elective deferrals.

The elective deferral limit for SIMPLE plans is 100% of compensation or \$17,000 in 2026, \$16,500 in 2025, \$16,000 in 2024, and \$15,500 in 2023. Catch-up contributions may also be allowed if the employee is age 50 or older.

Employers must deposit employee contributions to the retirement plan's trust or individual accounts as soon as they can reasonably be segregated from the employer's general assets.

| Readable Markdown | A contribution is the amount an employer and employees (including [self-employed](https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-plans-definitions "Retirement plans definitions") individuals) pay into a retirement plan.
## Limits on contributions and benefits
There are limits to how much employers and employees can contribute to a plan (or IRA) each year. The plan must specifically state that contributions or benefits cannot exceed certain limits. The limits differ depending on the type of plan.
- [IRA contribution limits](https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-topics-ira-contribution-limits "Retirement topics - IRA contribution limits")
- [401(k) and profit-sharing plan contribution limits](https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-topics-401k-and-profit-sharing-plan-contribution-limits "Retirement topics - 401(k) and profit-sharing plan contribution limits")
- [SEP contribution limits (including grandfathered SARSEPs)](https://www.irs.gov/retirement-plans/plan-participant-employee/sep-contribution-limits-including-grandfathered-sarseps "SEP contribution limits (including grandfathered SARSEPs)")
- [SIMPLE IRA contribution limits](https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-topics-simple-ira-contribution-limits "Retirement topics - SIMPLE IRA contribution limits")
- [403(b) contribution limits](https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-topics-403b-contribution-limits "Retirement Topics 403b Contribution Limits")
- [457(b) contribution limits](https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-topics-457b-contribution-limits "Retirement Topics 457b Contribution Limits")
- [Defined benefit plan benefit limits](https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-topics-defined-benefit-plan-benefit-limits "Retirement topics - Defined benefit plan benefit limits")
- [Catch-up contribution limits](https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-topics-catch-up-contributions "Retirement topics - Catch-up contributions")
## Basic elective deferral limit
The basic limit on elective deferrals is [\$24,500](https://www.irs.gov/retirement-plans/cola-increases-for-dollar-limitations-on-benefits-and-contributions "COLA increases for dollar limitations on benefits and contributions") in 2026, \$23,500 in 2025, \$23,000 in 2024 and \$22,500 in 2023, or 100% of the employee's compensation, whichever is less. The elective deferral limit for SIMPLE plans is 100% of compensation or \$17,000 in 2026, \$16,500 in 2025, \$16,000 in 2024, and \$15,500 in 2023. Catch-up contributions may also be allowed if the employee is age 50 or older.
If the employee's total contributions [exceed the deferral limit](https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-topics-what-happens-when-an-employee-has-elective-deferrals-in-excess-of-the-limits "Retirement topics - What happens when an employee has elective deferrals in excess of the limits?"), the difference is included in the employee's gross income.
## Time for depositing elective deferrals
Employers must deposit employee contributions to the retirement plan's trust or individual accounts as soon as they can reasonably be segregated from the employer's general assets. The Department of Labor provides a [7-business-day safe harbor rule](https://www.dol.gov/newsroom/releases/ebsa/ebsa20080228-0 "7-business-day safe harbor rule") for employee contributions to plans with fewer than 100 participants.
If you haven't deposited employees' elective deferrals as soon as you could have, find out how you can [correct](https://www.irs.gov/retirement-plans/401k-plan-fix-it-guide-you-havent-timely-deposited-employee-elective-deferrals "401(k) Plan fix-it guide - You haven't timely deposited employee elective deferrals") this mistake.
## Employer contributions
- **Employer matching contributions.** If the [plan document](https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-plans-definitions "Retirement plans definitions") permits, the employer can make matching contributions for an employee who contributes elective deferrals (for example, 50 cents for each dollar deferred). Employer matching contributions can be discretionary (contributed in some years and not in others, depending on the company's decision) or mandatory, as in SIMPLE plans and Safe Harbor 401(k) plans.
- **Employer discretionary or non-elective contributions.** If the plan document permits, the employer can make contributions other than matching contributions for participants. These contributions are made on behalf of all employees who are plan participants, including participants who choose not to contribute elective deferrals.
## Types of employee contributions
- **Salary reduction/**[**elective deferral**](https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-plans-definitions "Retirement plans definitions") **contributions** are pre-tax employee contributions that are a generally a percentage of the employee's compensation. Some plans permit the employee to contribute a specific dollar amount each pay period. [401(k), 403(b) or SIMPLE IRA plans](https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-plans-definitions "Retirement plans definitions") may permit elective deferral contributions.
- [**Designated Roth contributions**](https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-topics-designated-roth-account "Retirement topics - Designated Roth account") are a type of elective contribution that, unlike pre-tax elective contributions, are currently includible in gross income but tax-free when distributed. 401(k), 403(b) and governmental 457(b) plans can allow them. If a plan permits designated Roth contributions, it must also offer pre-tax elective deferral contributions.
- [**After-tax contributions**](https://www.irs.gov/publications/p571 "Publication 571 (01/2026), Tax-Sheltered Annuity Plans (403(b) Plans)") are contributions from compensation (other than Roth contributions) that an employee must include in income on his or her tax return. If a plan allows after-tax contributions, they are not excluded from income and an employee cannot deduct them on his or her tax return.
- [**Catch-up contributions**](https://www.irs.gov/retirement-plans/plan-participant-employee/retirement-topics-catch-up-contributions "Retirement topics - Catch-up contributions") if permitted by a 401(k), 403(b), governmental 457(b), SARSEP or SIMPLE IRA plan, participants who are age 50 or over at the end of the calendar year can also make catch-up elective deferral contributions beyond the basic limit on elective deferrals.
