Schedule C Line 19: Pension and Profit-Sharing Plans Deduction Explained for Freelancers (2026 Guide)

Published: May 24, 2026 · Reading time: 9 min

TL;DR: Schedule C Line 19 — Pension and profit-sharing plans is for the retirement contributions you make as the employer for your W-2 employees: SEP-IRA, SIMPLE-IRA, 401(k) match and profit-sharing, and defined-benefit/cash-balance contributions. Your own contribution as a sole proprietor is NOT on Line 19 — it goes above the line on Schedule 1 Line 16. The 2026 defined-contribution ceiling is the §415(c) limit of $70,000 ($77,500 with the 401(k) catch-up); defined-benefit plans use the §415(b) $280,000 benefit limit. Line 19 is governed by the §404 deduction limits, sits next to Line 14 (non-retirement benefits) and Line 26 (wages), and a new plan can earn the §45E start-up credit on Form 8881. If you have no employees, Line 19 is blank.

Most solo freelancers leave Schedule C Line 19 empty — and that's usually correct. Line 19 is reserved for the retirement money you put away for people who work for you, not for yourself. The moment you confuse the two, you either lose a deduction or trigger an IRS notice. Here's exactly what belongs on Line 19, what belongs on Schedule 1 Line 16 instead, and how the 2026 contribution limits actually work.

What "Pension and Profit-Sharing Plans" Means on Schedule C

The IRS Schedule C instructions define Line 19 as the deductible employer contributions to qualified retirement plans for your employees. The covered plan types are:

• SEP-IRA — Simplified Employee Pension (employer contributions only)
• SIMPLE-IRA — Savings Incentive Match Plan for Employees
• 401(k) — employer matching and profit-sharing contributions
• Profit-sharing plans — discretionary employer contributions
• Money-purchase pension plans — fixed-formula employer contributions
• Defined-benefit and cash-balance plans — actuarially determined contributions

Excluded from Line 19 (each has its own home):

The reason for the owner carve-out is structural: a sole proprietor is the owner, not an employee, of the unincorporated business. Their retirement contribution is a personal adjustment to income, not a business expense, so it never reduces Schedule C net profit. See our SEP-IRA vs Solo 401(k) guide for how the owner-side math works.

The Owner vs Employee Split (the #1 Line 19 Mistake)

This is worth its own section because it is the most common error practitioners catch on Line 19.

• Contributions for employees → deductible on Schedule C Line 19, reducing net profit (and therefore SE tax and QBI).
• Contributions for the owner → deductible on Schedule 1 Line 16, reducing AGI but NOT Schedule C net profit (preserving the QBI base and the SE-tax base).

Why it matters: if you wrongly drop your own $20,000 Solo 401(k) contribution onto Line 19, you reduce Schedule C net profit by $20,000. That shrinks your §199A QBI deduction (roughly 20% of $20,000 = $4,000 of lost QBI), understates your net earnings from self-employment, and mismatches what you actually report on Schedule 1. The IRS reconciles Line 16 against Form 1040 retirement-plan worksheets — a mismatch is an easy automated flag.

The Major Plan Types Inside Line 19

1. SEP-IRA

A SEP lets the employer contribute up to 25% of each eligible employee's compensation, capped at the §415(c) limit of $70,000 for 2026. The defining feature: contributions are employer-only and must be uniform — if you put in 10% for yourself, you generally must put in 10% for every eligible employee. The employee-coverage cost lands on Line 19; your own goes on Schedule 1 Line 16.

2. SIMPLE-IRA

Designed for businesses with 100 or fewer employees. Employees defer up to $16,500 for 2026 (plus a $3,500 catch-up at 50+), and the employer either matches up to 3% of compensation or makes a 2% non-elective contribution for all eligible employees. The employer match/non-elective portion for employees goes on Line 19.

3. 401(k) — Employer Match and Profit-Sharing

In a 401(k) that covers employees, the employee elective deferrals are already inside the wages on Line 26 (excluded from W-2 box 1). What lands on Line 19 is the employer money: the match and any profit-sharing contribution for employees. Total annual additions per participant cannot exceed the §415(c) limit of $70,000 ($77,500 with the age-50 catch-up; higher for the SECURE 2.0 ages 60–63 super catch-up).

4. Defined-Benefit and Cash-Balance Plans

These promise a future benefit and require an actuary to compute the annual funding amount. The ceiling is the §415(b) annual benefit limit of $280,000 for 2026, which can translate into employer contributions far above the $70,000 defined-contribution cap. The employee-coverage portion is deductible on Line 19. For high earners running these owner-heavy, see our defined benefit plan guide.

The §404 Deduction Limits

The amount you can actually deduct (as opposed to contribute) is governed by IRC §404:

• §404(a)(3) — profit-sharing and stock-bonus plans: deduction capped at 25% of total compensation paid to eligible participants.
• §404(h) — SEP: same 25%-of-compensation ceiling.
• §404(a)(7) — combined defined-benefit + defined-contribution plans: a special overall limit, with the small-plan exception that lets many owner-only DB + DC stacks deduct both.
• §404(o) — defined-benefit plans: deduction up to the actuarially determined funding target.

For an unincorporated owner, the 25% rate is applied to net earnings from self-employment, and because the contribution reduces that same compensation base, the effective rate becomes 20% of net SE earnings. That's why a sole prop with $100,000 of net SE earnings can contribute roughly $20,000 to a SEP, not $25,000.

The §45E Start-Up Credit (Form 8881)

If you start a new SEP, SIMPLE, or qualified plan, IRC §45E gives an eligible small employer (100 or fewer employees who earned at least $5,000) a start-up credit on Form 8881:

• Up to 100% of qualifying start-up costs for employers with 50 or fewer employees (50% for 51–100 employees)
• Capped at the greater of $500 or $250 per non-highly-compensated employee, up to $5,000/year for the first three plan years
• A separate employer-contribution credit under SECURE 2.0 of up to $1,000 per employee, phasing down over five years

Under the §45E(e)(2) no-double-benefit rule, costs you take as a credit can't also be deducted on Line 19 — but a dollar of credit beats a dollar of deduction every time. This is a key reason 2026 is a good year to launch an employee plan.

Line 19 vs Line 14 vs Line 26: The Three-Way Split

See our Schedule C Line 14 guide and Schedule C Line 26 wages guide for the adjacent lines.

Worked Example: Two-Employee Design Studio

A sole proprietor runs a design studio in 2026 with two W-2 employees and sponsors a 401(k) with a 4% employer match plus a SEP for a part-timer:

Line 19 total: $10,800 (employer match + profit-sharing for employees), reduced by the $1,500 of costs taken as the §45E credit. The owner's $40,000 contribution stays entirely off Schedule C — it's an above-the-line adjustment on Schedule 1.

Common Mistakes on Line 19

1. Owner's own contribution on Line 19 instead of Schedule 1 Line 16 — costs QBI and distorts SE earnings
2. Deducting employee elective deferrals on Line 19 — they're already inside Line 26 wages
3. Mixing retirement (Line 19) with health benefits (Line 14)
4. Exceeding the §404 25%-of-compensation ceiling for SEP/profit-sharing
5. Forgetting the §45E credit when starting a new plan — leaving up to $5,000/year on the table
6. Contributing for ineligible employees (failing the SEP/SIMPLE eligibility rules), risking plan disqualification
7. Missing the contribution deadline — employer contributions are deductible if made by the return due date including extensions

Workflow That Keeps Line 19 Clean

1. Run the plan through a provider — Guideline, Human Interest, Vanguard, Fidelity, or your payroll platform (Gusto, Justworks) — which produces a year-end contribution report split by participant.
2. Tag employer-for-employee dollars to Line 19 and owner dollars to a separate "Schedule 1 Line 16" bucket in your bookkeeping; never co-mingle them.
3. Reconcile against Form 5500 if your plan is large enough to require one.
4. Claim Form 8881 in the first three plan years for the §45E start-up credit.
5. Confirm the deadline — fund employer contributions by the extended return due date to deduct them for the year.
