The Truth About S Corp vs C Corp Tax Advantages 2019: How Strategy, Not Entity Type, Defines Your Savings

The fear of making the wrong decision between an S Corp and a C Corp has lingered over business owners for years. In 2019, thousands defaulted to what their lawyer or friend suggested—rarely understanding the six-figure stakes. The right choice is still misunderstood today, and the IRS doesn’t spell out your best move. Let’s cut through the confusion and show you, with numbers, how the entity selection itself rarely moves the needle—strategy does.

Quick Tax Answer: In 2019, S Corps and C Corps offered dramatically different tax profiles. S Corps passed income through to owners—potentially eliminating double taxation—while C Corps faced a flat 21% tax, but allowed medical deductions and retained earnings. For most owners, entity setup wasn’t the win. It was leveraging the structure for custom salary, distribution, and deduction strategies.

The Real 2019 Differences: S Corp vs C Corp Tax Advantages

Let’s put the s corp vs c corp tax advantages 2019 debate into plain English. The S Corp “advantage” isn’t just about skipping double taxation. Sure, S Corps don’t pay federal entity-level tax; their profits flow to owners’ returns. But in 2019, every dollar an S Corp owner took as a salary was subject to Social Security and Medicare taxes—over 15% combined—while their distributions were not.

The C Corp, post-TCJA, paid a flat 21% rate from 2018 onward (down from 35%), but profits distributed as dividends faced a second layer of tax at the individual’s rate (15–23.8%). C Corps could retain earnings and deduct fringe benefits (like health insurance) unavailable to S Corps, but any cash coming to your pocket was hit twice.

• Example: Jenny owns an S Corp with $220,000 profit in 2019. She pays herself $80,000 salary. She only pays payroll taxes on the $80,000, not the $140,000 left as a distribution—saving over $17,000 in payroll tax compared to a Schedule C or LLC.
• Compare with a C Corp: If Jenny’s C Corp earns $220,000 pre-tax, the corporation pays $46,200 (21%) in federal tax. If she pays out all profits as a dividend, she’s taxed again (potential $8,799 at 15% qualified dividends), so her net cash is less than with an S Corp and she loses some self-employment tax flexibility.

This is just one scenario—complexities multiply if you add retirement plans, owner health benefits, or retain profits for growth.

Why These Choices Still Matter for Business Owners

Every entity comes with unique rules, and California (and other states) adds its own twist. Owners who blindly elect S Corp status assume the payroll savings outweigh the extra compliance and FTB fee headaches. But C Corps in California face an 8.84% state tax; S Corps pay 1.5% of net income (minimum $800), but their owners might get nickel-and-dimed with city, state, or franchise taxes depending on their operations.

KDA Case Study: Contractor Rebuilds Tax Plan—$29,400 Saved

Persona: Construction contractor, sole shareholder S Corp, $320,000 annual revenue (2019). This client was structured as an S Corp but only drew payroll of $36,000—far below a “reasonable” amount for their role. The IRS flagged them for audit. We rebuilt their payroll to $75,000 (with supporting industry wage data), reclassified distributions, and late-elected C Corp for specific passive income lines. The S Corp side triggered a smaller payroll tax bill—saving about $9,000—but the bonus was in C Corp health benefit deductions and retained earnings. Over the audit cycle and first year post-adjustment, the blended approach saved over $29,400 versus the old setup. Our fee: $6,500—first-year ROI above 4.5x.

Owner Payroll and Fringe Deductions: Hidden Traps of 2019

Payroll and benefits are where most new S Corp and C Corp owners fumble. In 2019, S Corp owners were required to pay themselves a “reasonable salary” (see IRS S Corp rules), but this was rarely defined. Payroll set below industry norms was a ticket to audit. Meanwhile, C Corps could offer greater fringe benefits—particularly medical, dental, and disability—often tax-free to owners. But fail to structure it properly, and you lose both deductions and compliance safety.

• Trap: Failing to pay S Corp W-2 salary = IRS reclassification, payroll back taxes, and penalties.
• Trap: Taking full C Corp profit as distribution versus keeping it in the business and using fringe benefits = big net cash loss.

Pro Tip: Lock in your “reasonable compensation” with data (like the Radford survey or Salary.com) and review entity benefits annually as profit grows.

Common Mistake That Triggers an Audit

Many owners in 2019 picked S Corp status for payroll savings, then forgot to adjust as profit rose. The IRS has gotten aggressive: set your salary too low on purpose, and they will reclassify your distributions—they have been doing this since at least Revenue Ruling 74-44—and the penalties often exceed $20,000. This is avoidable with annual review and compensation benchmarking.

Red Flag Alert: Payroll “lowballing” doesn’t simply redistribute taxes; it blows up your liability and can trigger both federal and state audits. Use strong documentation every year to justify your salary decision.

Can You Stack S Corps and C Corps for More Savings?

Can a business combine both entities for added tax optimization? In select cases, yes. In the 2019 tax environment, an S Corp could flow active income to owners, while a C Corp could be used for specific lines of business (like property holdings, equipment rental, or IP licensing). This lets you control payroll tax exposure and capture C Corp fringe benefits—if executed with care and strong legal guidance.

• Scenario: A real estate broker operates a primary sales company as an S Corp and a separate holdings company as a C Corp. Profits retained in the C Corp fund long-term investments, while the S Corp flows cash to the owner at a tax-advantaged rate. This structure saved a KDA client $17,000 per year on FICA, plus an extra $4,800 through C Corp medical plans.

Each business requires custom analysis. Layering entities can amplify savings—but gets you in audit crosshairs fast if not done right.

FAQ: Deeper Dive Into Entity Selection for 2019

Who Should Use an S Corp for 2019?

If you are a service professional or consultant making at least $60,000 net a year (and working alone or with a spouse), an S Corp likely cut your payroll tax—but only if you handled compliance, payroll, and documentation properly. Owners with large profits or multiple partners have extra hurdles and need customized plans.

Is a C Corp Better for High Retained Earnings?

If your plan is to keep profits inside the company for reinvestment, or your business needs rich owner benefits (especiaaly medical, dental, or group term life), a C Corp could provide more flexibility. Watch out for state taxes and potential double-taxation if you distribute profits as dividends.
