Decision Guide
C Corp or S Corp? A Decision Guide by Business Profile (2026)
Every comparison article gives one generic answer. The real answer depends on your profile. Eight specific business profiles with a clear recommendation, three specific reasons, and the threshold for reconsidering.

Pre-revenue to any
VC-backed or VC-track startup
Why
- +Investors require preferred stock, which S-Corp prohibits.
- +QSBS Section 1202: up to $10M+ of founder gain can be tax-free at exit.
- +Foreign investors and entity investors cannot hold S-Corp stock.
When to reconsider
Never for VC-track. Even pre-revenue, the QSBS five-year clock starts from day one as a C-Corp. Incorporate correctly from the start.
$50k-$2M net
Bootstrapped SaaS, $50k-$2M ARR, no fundraising plans
Why
- +Pass-through avoids double tax on profits you want to take home.
- +SE-tax saving on distributions above reasonable salary adds $5k-$25k/yr net of compliance.
- +Convert to C-Corp later if you decide to raise VC (QSBS clock resets, but at that point revenue justifies the cost).
When to reconsider
If you plan to raise VC or need preferred stock, convert to C-Corp before signing a term sheet.
$150k-$1M net
Profitable services firm (consulting, agency, dental, law)
Why
- +Highest SE-tax saving of any profile. Income is regular and above the breakeven.
- +Reasonable salary defensible via BLS OEWS comps for your occupation and MSA.
- +QBI 199A deduction adds further savings below the SSTB phase-out threshold.
When to reconsider
Above $191,950 single / $383,900 MFJ, QBI disappears but SE-tax saving still applies. CA owners: add the $800 + 1.5% franchise tax cost to your analysis.
$200k-$1M+ net
Solo high-income consultant, $300k+ net, no employees
Why
- +Salary capped at SS wage base ($168,600); excess distributions save 2.9% Medicare on income above that.
- +Additional Medicare Tax (0.9%) on earned income above $200k single also saved on distributions.
- +QBI likely phased out at this income level, but pure FICA saving is significant.
When to reconsider
If your consulting is SSTB-classified and above the QBI threshold, QBI benefit is zero. The pure FICA saving still justifies S-Corp election at this income level.
Any
Real estate investor with rental properties
Why
- +LLC partnership preserves depreciation pass-through and Section 1231 gain treatment.
- +S-Corp restricts depreciation recapture on distributions and triggers tax on appreciated property transfers.
- +C-Corp creates double tax on rental income and eliminates 1231 gain treatment at sale.
When to reconsider
Exception: a real estate agent or broker running a commission-based service business (not holding investment properties) can use S-Corp for SE-tax savings on commissions.
Any profitable
Family business, multi-generational
Why
- +QSST and ESBT trust elections allow shares in trusts for estate planning purposes.
- +Family member counting rules (IRC 1361(c)(1)) allow up to 6 generations to count as one shareholder.
- +Pass-through avoids double tax while keeping the business in the family.
When to reconsider
Watch the 100-shareholder cap as the family expands. Annual count verification is important when shares are held by multiple trusts and family branches.
Pre-revenue to early revenue
High-growth bootstrapped startup, considering VC eventually
Why
- +Start the QSBS five-year clock from day one. At low revenue the cost (no SE-tax savings) is small.
- +The QSBS option value is asymmetric: a successful exit can generate millions in tax-free gain.
- +C-Corp makes the future VC fundraise seamless; avoiding S-to-C conversion saves legal cost and clock reset.
When to reconsider
If your business is clearly never going to raise VC and will generate modest profits, the SE-tax saving from S-Corp may outweigh the QSBS option value.
$200k-$500k+ net
Solo professional in CA or NY with significant income
Why
- +California: S-Corp adds $800 + 1.5% entity franchise tax. At $300k net income that is $5,300 the S-Corp pays that a sole proprietor does not.
- +New York: without Form CT-6, NY treats the entity as a C-Corp. With CT-6, NY still has minimum fixed-dollar taxes and MTA surcharge.
- +C-Corp at 21% may be competitive if you retain earnings with documented business purposes and can defend the AET.
When to reconsider
Run the numbers in the calculator with your income, state, and distribution plan before deciding. Both answers are plausible at different income levels.

Use the tax calculator with your specific income, state, filing status, and planned salary. Also see QSBS if you have any realistic chance of a startup exit in the next 5-10 years.
