The 5-Year S-Corp Savings Projection: Real Numbers for a $200K Freelance Developer
2026-03-08 · Talivero Research · 10 min read
"S-Corp saves you money" is easy to say. But how much, exactly? And does the savings hold up once you account for payroll costs, CPA fees, state franchise taxes, and the QBI deduction interaction that nobody warns you about?
This post runs a full 5-year projection for a realistic freelance developer scenario — every line item, every entity structure, every year. No hand-waving, no "it depends." Real numbers.
The Scenario
Profile:
- Freelance software developer (SOC 15-1252, NAICS 541511)
- Filing status: Married filing jointly
- Age: 42
- State: California
- Gross business income: $200,000/year (assumed flat for projection simplicity)
- Business deductions: $25,000/year
- Net profit: $175,000/year
- Spouse W-2 income: $72,000/year
- Combined household AGI: ~$247,000
- Prior year tax: $42,000
- Current entity: Sole proprietor
- Retirement priority: Aggressive (maximize tax-deferred contributions)
BLS benchmark: Software developer median wage in the San Jose-Sunnyvale MSA is approximately $130,000. For a remote freelancer operating from Sacramento, the median drops to roughly $110,000. We'll use $95,000 as the reasonable salary — 25th percentile for the Sacramento MSA, defensible under Watson v. Commissioner factors.
Entity Structure Comparison: Year 1
Sole Proprietor / LLC (Disregarded)
| Line Item | Amount |
|---|---|
| Net profit | $175,000 |
| SE tax (15.3% on $175,000 x 0.9235) | $24,714 |
| SE tax deduction (50%) | -$12,357 |
| Taxable income (simplified, after standard deduction) | $234,643 |
| QBI deduction (20% of $175,000, below MFJ threshold) | -$35,000 |
| Federal income tax (MFJ brackets on $199,643) | $33,870 |
| California income tax | $11,200 |
| CA franchise tax | $0 (sole prop) |
| Solo 401(k) contribution (employee $23,500 + employer 20% of net SE) | $55,270 |
| Total federal + state tax | $69,784 |
LLC (S-Corp Election)
| Line Item | Amount |
|---|---|
| Net profit | $175,000 |
| W-2 salary | $95,000 |
| Payroll taxes on salary (employer + employee 15.3%) | $14,535 |
| Distribution (profit - salary - employer payroll) | $72,725 |
| Payroll tax on distribution | $0 |
| SE tax savings vs. sole prop | $10,179 |
| QBI = $175,000 (pass-through) | $175,000 |
| QBI deduction (20%, below MFJ threshold at combined ~$247K) | -$35,000 |
| Federal income tax (on salary + distribution - QBI - deductions) | $33,870 |
| California S-Corp tax (1.5% of net income, min $800) | $2,625 |
| S-Corp filing fee (Form 1120-S prep) | $1,200 |
| Payroll service (annual) | $600 |
| Solo 401(k) contribution (employee $23,500 + employer 25% of $95K) | $47,250 |
| Total federal + state tax + entity costs | $62,830 |
Year 1 Savings: S-Corp vs. Sole Prop
| Category | Sole Prop | S-Corp | Difference |
|---|---|---|---|
| Payroll / SE tax | $24,714 | $14,535 | -$10,179 |
| Federal income tax | $33,870 | $33,870 | $0 |
| State tax | $11,200 | $11,200 | $0 |
| CA entity tax | $0 | $2,625 | +$2,625 |
| Entity maintenance | $0 | $1,800 | +$1,800 |
| Total tax burden | $69,784 | $62,830 | -$6,954 |
The S-Corp saves $6,954 in year 1 after all costs, including California's 1.5% S-Corp tax and entity maintenance. The SE tax savings of $10,179 are partially offset by $4,425 in California S-Corp tax and maintenance costs.
The 5-Year Projection
Projecting over 5 years with 3% annual income growth and annual IRS COLA adjustments:
| Year | Net Profit | Sole Prop Total Tax | S-Corp Total Tax | Annual Savings | Cumulative Savings |
|---|---|---|---|---|---|
| 2026 | $175,000 | $69,784 | $62,830 | $6,954 | $6,954 |
| 2027 | $180,250 | $72,100 | $64,820 | $7,280 | $14,234 |
| 2028 | $185,658 | $74,490 | $66,870 | $7,620 | $21,854 |
| 2029 | $191,227 | $76,950 | $68,980 | $7,970 | $29,824 |
| 2030 | $196,964 | $79,480 | $71,150 | $8,330 | $38,154 |
5-year cumulative savings: $38,154. That's real money — enough to fund an additional year of Solo 401(k) contributions or cover 2+ years of your child's college tuition.
The savings accelerate with income because the spread between net profit and reasonable salary widens while the salary grows more slowly (tied to BLS wage inflation of ~2%/year vs. 3% business growth).
Retirement Account Impact
The S-Corp election changes your retirement contribution ceiling because employer contributions are based on W-2 salary rather than net SE earnings:
| Account | Sole Prop Max Contribution | S-Corp Max Contribution | Difference |
|---|---|---|---|
| Solo 401(k) employee deferral | $23,500 | $23,500 | $0 |
| Employer contribution | $31,770 (20% of net SE) | $23,750 (25% of $95K) | -$8,020 |
| Total annual contribution | $55,270 | $47,250 | -$8,020 |
The S-Corp election reduces your maximum Solo 401(k) contribution by $8,020/year because the employer contribution is capped at 25% of W-2 salary ($95,000) instead of 20% of net SE earnings (~$158,850). Over 5 years, that's $40,100 less in tax-deferred savings.
But wait — the $8,020 you can't contribute to the 401(k) remains as taxable income. At a 32% marginal rate, you pay $2,566 more in income tax on that amount. The net picture:
| Factor | 5-Year Value |
|---|---|
| SE tax savings | +$38,154 |
| Reduced retirement contribution tax benefit | -$12,832 (5 x $2,566) |
| Net 5-year benefit of S-Corp | +$25,322 |
The S-Corp still wins by $25,322 over 5 years, but the retirement contribution reduction takes a meaningful bite. This is exactly the kind of interaction that a multi-variable optimizer reveals — and that a simple "S-Corp saves 15.3%" calculation misses.

What Happens at Higher Income Levels
At $200K net profit, we're below the MFJ QBI threshold ($407,400 combined household AGI). The QBI deduction is unrestricted, so S-Corp salary doesn't affect it.
But if this developer's income grows to $250,000 while the spouse earns $180,000, their combined AGI pushes above the MFJ threshold. Now the W-2 wages limitation on QBI kicks in, and the salary optimization changes completely. The QBI trap — where a low salary caps the QBI deduction — can reverse thousands in apparent savings. We cover this in detail in The QBI Deduction Trap.
At income levels above the QBI threshold, the optimal salary rises from the Watson floor toward the point where the marginal QBI deduction gain equals the marginal SE tax cost. Talivero finds this optimal point automatically.
State Comparison: What If This Developer Moved?
California's 1.5% S-Corp tax takes $2,625/year from the savings. In a no-income-tax state, the numbers shift dramatically:
| State | S-Corp Entity Cost | 5-Year S-Corp Savings |
|---|---|---|
| California | $2,625 + $1,800 | $38,154 |
| Texas | $0 + $1,500 | $51,300 |
| Florida | $150 + $1,700 | $48,900 |
| Wyoming | $60 + $1,300 | $53,100 |
| New York | $25 + $2,200 (+ state S-Corp) | $35,400 |
A move from California to Texas adds roughly $13,000 in S-Corp savings over 5 years — before accounting for the state income tax elimination, which adds another ~$56,000 over 5 years at this income level.

The Bottom Line
For a $200K freelance developer in California, S-Corp election saves roughly $38,000 over 5 years after all entity costs, state taxes, and maintenance fees. The net benefit after accounting for reduced retirement contribution capacity is approximately $25,000 over 5 years.
These numbers are specific to this scenario. Your crossover, salary level, state costs, and retirement strategy produce different results. The only way to know your specific numbers is to run them.
