Key Takeaways
- The 2026 employee deferral limit is $24,500, but the total annual additions limit is $72,000.
- Profit sharing is the employer's non-elective contribution — it's what closes the gap between those two numbers.
- Catch-up contributions add $8,000 (age 50+) or $11,250 (age 60–63), pushing the ceiling to $80,000 or $83,250.
- Compensation above $360,000 can't be counted when calculating contributions.
- Profit sharing can be funded up until your business tax deadline, including extensions — well after December 31.
What Is a Profit Sharing Contribution?
A profit sharing contribution is money your business puts into employees' 401(k) accounts on top of any match, and it's entirely discretionary — you decide the amount and the formula each year. Unlike an employee's own deferral, or a match tied to what an employee defers, profit sharing doesn't require the employee to contribute anything at all. The business simply allocates a contribution, typically based on compensation, using a formula that satisfies IRS nondiscrimination rules.
The 2026 Numbers
Three limits matter here, and they stack differently. The employee deferral limit caps what you personally defer from pay. The annual additions limit caps the combined total of your deferral, any match, and profit sharing. Catch-up contributions sit outside both, if you're eligible.
| Limit | 2026 amount | Applies to |
|---|---|---|
| Employee elective deferral | $24,500 | What you personally defer from pay |
| Catch-up (age 50+) | $8,000 | Additional employee deferral |
| Super catch-up (age 60–63) | $11,250 | Replaces the standard catch-up |
| Annual additions limit (IRC §415(c)) | $72,000 | Deferral + match + profit sharing combined |
| Annual additions with catch-up | $80,000 – $83,250 | Same, plus catch-up on top |
| Compensation cap (IRC §401(a)(17)) | $360,000 | Max pay counted in any contribution formula |
How Much Can the Business Actually Deduct?
Your business can deduct profit sharing contributions up to 25% of the total eligible compensation paid to plan participants that year. This is a separate rule from the $72,000 annual additions limit — the 25% figure is a deduction ceiling at the business level, while the $72,000 figure is a contribution ceiling at the individual participant level.
It's easy to conflate these. The 25% deduction limit (IRC §404) controls what your business can write off in aggregate. The $72,000 annual additions limit (IRC §415(c)) controls what any one participant can receive. A small plan can easily hit the individual limit before the business gets anywhere near its aggregate deduction ceiling.
Solo 401(k): Where This Really Shines
If you're self-employed with no full-time employees, you can act as both the employee and the employer of your own plan — deferring $24,500 as "employee" and adding a profit sharing contribution as "employer," up to the combined $72,000 ceiling for 2026 (more with catch-up).
| Business type | Profit sharing formula |
|---|---|
| Sole proprietor / single-member LLC | ~20% of net self-employment income (after the deduction for one-half of self-employment tax) |
| S-corp owner | 25% of W-2 wages |
| C-corp owner | 25% of W-2 compensation |
An S-corp owner, age 55, pays herself $300,000 in W-2 wages. She defers $24,500 as employee, plus an $8,000 catch-up. Her business can add profit sharing up to 25% of $300,000 ($75,000) — but the combined employee deferral and profit sharing can't exceed the $72,000 annual additions limit (catch-up sits outside it). So her maximum profit sharing contribution is $72,000 − $24,500 = $47,500. Total for the year: $24,500 + $8,000 + $47,500 = $80,000.
When to Make the Contribution
Profit sharing contributions can be made up until your business's tax filing deadline, including extensions — not December 31 like employee deferrals. That means a sole proprietor or single-member LLC generally has until April 15 (or October 15 with an extension), and an S-corp or partnership generally has until March 15 (or September 15 with an extension), to decide the exact amount once full-year numbers are known.
If You Have Employees: Allocation Formulas Matter
How you allocate profit sharing matters as much as how much you contribute. A pro-rata formula gives every participant the same percentage of pay. A new comparability (age-weighted) formula can be designed, with actuarial testing, to direct a larger share toward owners and older, higher-paid employees — often the point of the plan for a business owner in the first place.
How to Make the Most of It
- Don't confuse the two ceilings. The $24,500 employee limit and the $72,000 annual additions limit are different numbers doing different jobs.
- Calculate net self-employment income correctly. Sole proprietors apply the profit sharing percentage after deducting one-half of self-employment tax — get this step wrong and the contribution is wrong too.
- Consider a new comparability formula if you have employees and want contributions to favor owners — this requires a TPA and annual testing.
- Use the extended deadline deliberately. Wait until you know full-year business results before locking in the exact profit sharing amount.
- Watch the $360,000 compensation cap if you or another owner is highly paid — pay above that level doesn't count in the formula.
Frequently Asked Questions
What is a 401(k) profit sharing contribution?
It's a discretionary, non-elective contribution your business makes to employees' 401(k) accounts, separate from any employee deferral or matching contribution.
Is profit sharing the same as an employer match?
No. A match is tied to what an employee defers. Profit sharing is discretionary and doesn't require the employee to contribute anything at all.
How much can my business contribute in profit sharing for 2026?
Up to 25% of eligible compensation paid to plan participants, subject to the overall $72,000 annual additions limit per person for 2026 (or $80,000–$83,250 with catch-up).
What's the deadline to make a profit sharing contribution?
Your business tax filing deadline, including extensions — often well after December 31, unlike employee elective deferrals.
Can I do profit sharing in a Solo 401(k)?
Yes. Self-employed individuals with no full-time employees can contribute as both employee and employer, combining a $24,500 deferral with a profit sharing contribution up to the combined $72,000 cap for 2026.
Does profit sharing count toward my $24,500 employee limit?
No. Profit sharing is an employer contribution and sits on top of the employee deferral limit, though both count toward the combined $72,000 annual additions limit.
