A discretionary profit-sharing plan is a qualified retirement plan that lets the employer decide each year whether to make a contribution and how much, with no obligation to contribute in any given year. For 2026, total annual additions to a participant’s account can reach $72,000, and the business can deduct contributions up to 25% of total eligible payroll. That mix of flexibility for the company and tax-deferred growth for employees makes it one of the most common retirement arrangements at small and mid-size businesses.
How the Discretionary Contribution Decision Works
The word “discretionary” carries the whole idea. The employer might contribute 10% of payroll in a strong year, 3% in a lean one, and nothing during a downturn. No formula locks the business in, and employees have no legal right to demand a contribution in any particular year.
The decision usually gets made close to the tax filing deadline. Contributions are deductible in the year they’re designated for even if the money actually moves later. Employers have until the due date of their tax return, including extensions, to fund the contribution for the prior year.1Internal Revenue Service. Publication 560 (2025), Retirement Plans for Small Business A calendar-year business filing on extension could make its 2025 contribution as late as October 2026 and still deduct it on the 2025 return.
Since the SECURE Act, an employer can also establish a new profit-sharing plan retroactively. A business that had no plan during the tax year can adopt one by the extended filing deadline and elect to treat it as if it existed on the last day of that prior year.2Internal Revenue Service. Issue Snapshot – Deductibility of Employer Contributions to a 401(k) Plan Made After the End of the Tax Year That is a meaningful planning tool for owners who close the books on an unexpectedly profitable year.
Contribution Limits
Two separate caps govern the money flowing into the plan: one on the employer’s deduction, one on any single participant’s account.
Employer Deduction Limit
The business can deduct contributions up to 25% of the total compensation paid to all participating employees during the year.3Office of the Law Revision Counsel. 26 USC 404 – Deduction for Contributions of an Employer to an Employees Trust Contributions above the 25% threshold aren’t lost, but they carry forward to future tax years rather than being deducted currently.
Individual Annual Additions Limit
For 2026, total annual additions to any single participant’s account cannot exceed the lesser of 100% of that person’s compensation or $72,000.4Internal Revenue Service. COLA Increases for Dollar Limitations on Benefits and Contributions Annual additions include employer contributions and any reallocated forfeitures. If the plan also has a 401(k) feature, employee deferrals count toward the same $72,000 cap, though participants ages 60 to 63 can go higher under SECURE 2.0’s enhanced catch-up rules.5Internal Revenue Service. Retirement Topics – 401(k) and Profit-Sharing Plan Contribution Limits
Compensation Cap
Only the first $360,000 of any employee’s pay counts toward contribution calculations in 2026.4Internal Revenue Service. COLA Increases for Dollar Limitations on Benefits and Contributions An employee earning $500,000 is treated identically to one earning $360,000 for plan purposes. This cap matters most when checking whether the allocation formula passes nondiscrimination testing.
How Contributions Get Divided Among Employees
Once the employer decides on a total contribution, the plan document’s allocation formula determines each participant’s share. The choice has real strategic weight, especially for owners trying to maximize their own retirement savings.
Pro-Rata Allocation
The simplest formula gives every participant the same percentage of compensation. If the employer funds an amount equal to 10% of total payroll, each participant receives 10% of their individual pay. Easy to administer, but it offers no way to direct more toward any particular person.
Social Security Integration
An integrated formula gives participants a higher allocation rate on compensation above the Social Security taxable wage base, which is $184,500 for 2026.6Social Security Administration. Contribution and Benefit Base The reasoning is that the employer already pays Social Security tax on wages below that threshold, so the plan compensates with a larger contribution on earnings above it. The spread between the two rates is capped by regulation.
Cross-Tested (New Comparability) Plans
Cross-tested plans test whether the projected retirement benefit each participant would receive is nondiscriminatory, rather than whether current contributions are equal. Because older participants have fewer years until retirement, the plan can allocate a much larger current contribution to them and still pass. A 55-year-old owner might receive 20% of compensation while a 30-year-old employee gets 5%. Annual actuarial testing is required, which adds administrative cost.
Who Can Participate and When They Own the Money
The plan must be established through a written document that meets IRS qualification rules, with a trust holding the assets solely for participants’ benefit.
A plan cannot require employees to be older than 21 or to have more than one year of service before participating. One exception: a plan without a 401(k) feature can require two years of service, but only if all employer contributions vest immediately.7Internal Revenue Service. Retirement Topics – Eligibility and Participation
For plan years after 2024, SECURE 2.0 requires plans to cover long-term part-time workers. Employees who log at least 500 hours in each of two consecutive 12-month periods must be allowed in, even if they never hit the traditional 1,000-hour “year of service” threshold.8Internal Revenue Service. Additional Guidance with Respect to Long-Term, Part-Time Employees Many small employers still aren’t aware of this change, and missing it creates compliance problems.
Vesting determines how much of the employer’s contributions a participant owns if they leave. Profit-sharing plans use one of two minimum schedules:
- Three-year cliff: 0% ownership until three years of service, then 100% all at once.
- Six-year graded: 20% after two years, increasing gradually to 100% after six years.
Plans can vest faster than these minimums, and some vest immediately.9Internal Revenue Service. Retirement Topics – Vesting Unvested amounts forfeited by departing employees typically get reallocated among remaining participants or used to reduce future employer contributions.
Nondiscrimination and Top-Heavy Rules
Profit-sharing plans receive favorable tax treatment because Congress intended them to benefit rank-and-file employees, not just owners and executives. Two rule sets enforce that.
Nondiscrimination Testing
Every profit-sharing plan must satisfy IRC Section 401(a)(4), which compares contributions received by highly compensated employees to those received by everyone else.10Office of the Law Revision Counsel. 26 U.S. Code 401 – Qualified Pension, Profit-Sharing, and Stock Bonus Plans A “highly compensated employee” is generally someone who earned above an annually adjusted threshold in the prior year or who owns more than 5% of the business. The allocation formula determines the specific testing method, but the plan cannot disproportionately favor the higher-paid group.
Failing this test is expensive. There is a limited correction window, and an uncorrected failure can cost the plan its tax-qualified status. Correction typically means additional contributions for lower-paid employees or refunds to the highly compensated group.
Top-Heavy Rules
A plan is top-heavy when key employees hold more than 60% of total plan assets.11Office of the Law Revision Counsel. 26 U.S. Code 416 – Special Rules for Top-Heavy Plans Key employees include officers earning more than $235,000 in 2026, anyone owning at least 5% of the business, and 1% owners earning over $150,000. Most small-business plans end up top-heavy, especially in the early years when the owner’s account dwarfs everyone else’s.
When a plan is top-heavy, the employer must contribute at least 3% of compensation for every eligible non-key employee, whether or not the employer makes a discretionary contribution that year.12Office of the Law Revision Counsel. 26 U.S. Code 416 – Special Rules for Top-Heavy Plans – Section (c)(2) This is where “discretionary” carries a practical asterisk. You have no obligation to contribute, but if your plan is top-heavy and you contribute anything for yourself, you owe the 3% minimum to staff.
Tax Treatment for Participants
Employer contributions don’t appear on participants’ W-2s. Money goes into the plan pre-tax and grows without annual taxation on dividends, interest, or capital gains. The employer, meanwhile, deducts the full contribution as a business expense in the year it’s designated for.3Office of the Law Revision Counsel. 26 USC 404 – Deduction for Contributions of an Employer to an Employees Trust
Distributions are taxed as ordinary income. Withdrawals before age 59½ carry an additional 10% early withdrawal penalty on top of regular income tax.13Internal Revenue Service. Topic No. 558, Additional Tax on Early Distributions from Retirement Plans Other Than IRAs Several exceptions avoid the penalty, including total disability, separation from service at age 55 or older, and unreimbursed medical expenses above 7.5% of adjusted gross income.14Internal Revenue Service. Retirement Topics – Exceptions to Tax on Early Distributions
Rollovers preserve the tax deferral. A direct rollover moves the balance from plan to plan or plan to IRA without passing through your hands. If the distribution is paid to you instead, the plan must withhold 20% for taxes, and you have 60 days to deposit the full amount (including making up the withheld portion from other funds) into a qualifying account to avoid taxation.15Internal Revenue Service. Rollovers of Retirement Plan and IRA Distributions
You can’t leave money in the plan indefinitely. Required minimum distributions must begin by April 1 of the year after you turn 73 if you were born between 1951 and 1959, or age 75 if you were born in 1960 or later. If you’re still working for the plan sponsor and you don’t own more than 5% of the business, you can generally delay RMDs until you retire.
Loans
Profit-sharing plans can include a loan feature, though not every plan does. Where allowed, participants can borrow up to the lesser of $50,000 or 50% of their vested balance. Repayment runs over five years through substantially level payments made at least quarterly, unless the loan finances a primary residence, which gets a longer window.16eCFR. 26 CFR 1.72(p)-1 – Loans Treated as Distributions Amounts exceeding these limits or not repaid on schedule become taxable distributions, with the 10% penalty applying if you’re under 59½.
Ongoing Administration
Every plan must file Form 5500 (or Form 5500-SF for smaller plans) each year with the Department of Labor.17U.S. Department of Labor. Form 5500 Series The filing is due the last day of the seventh month after the plan year ends (July 31 for calendar-year plans), with an automatic 2½-month extension available by filing Form 5558 before the original deadline.
Late filing is costly. The IRS charges $250 per day, up to $150,000.18Internal Revenue Service. Form 5500 Corner The DOL adds its own separate daily penalty. These stack, so a forgotten filing gets shockingly expensive fast.
Anyone who manages plan assets or makes decisions about plan operations is a fiduciary under ERISA. Fiduciaries must act solely in the interest of participants, invest prudently, diversify to minimize the risk of large losses, and keep expenses reasonable. Personal liability attaches to fiduciary breaches, so the individual decision-maker can be on the hook, not just the company.
Operational errors are common and often fixable. The IRS allows many mistakes to be self-corrected without paperwork or fees when the sponsor had reasonable procedures in place and the error was an honest oversight.19Internal Revenue Service. Retirement Plan Errors Eligible for Self-Correction Minor errors can be fixed at any time; significant ones must be corrected within a limited window. Errors in the plan document itself, such as a missing required amendment, cannot be self-corrected and require a formal IRS submission. The catch: self-correction assumes you were actually following documented procedures. A plan document sitting in a drawer doesn’t count.
Terminating the Plan
Employers can end a profit-sharing plan, but the process involves more than turning off contributions. The IRS requires several steps:
- All participants become 100% vested as of the termination date, regardless of years worked.
- The plan document is formally amended to set a termination date and stop contributions.
- All plan assets are distributed to participants as soon as administratively feasible, generally within 12 months.
- Participants receive notice of their right to roll distributions into an IRA or another plan.
- A final Form 5500 is filed.
The employer can also request a determination letter from the IRS confirming the plan was compliant at termination, which provides some protection against future audits.20Internal Revenue Service. Terminating a Retirement Plan The full-vesting requirement is worth taking seriously. If you’ve been using a vesting schedule to retain employees, every unvested dollar becomes theirs the moment you terminate.
