An S Corporation avoids self-employment (SE) tax by splitting owner compensation into a "reasonable salary" and profit distributions. Only the salary is subject to 15.3% FICA payroll taxes, while the remaining profits (distributions) pass through to shareholders free from self-employment taxes.
Shareholders must include their share of the income on their tax return whether or not it is distributed to them. Unlike most partnership income, S corporation income isn't self-employment income and isn't subject to self-employment tax.
How Can Business Deductions Lower S Corp Taxes?
Choose the Right Business Structure
Sole proprietors and single-member LLCs pay full self-employment tax on all profits. However, if your income exceeds a certain threshold, switching to an S Corporation (S-Corp) could significantly reduce your SE taxes.
The "2% rule" for S Corporations treats shareholders owning more than 2% of the company's stock (or voting power) differently for fringe benefits, classifying them like partners in a partnership, not regular employees; this means benefits like health insurance premiums paid by the S Corp must be included as taxable wages on their W-2, rather than being tax-free, though the shareholder can often deduct these premiums as an "above-the-line" deduction. This rule prevents them from participating in tax-advantaged Section 125 cafeteria plans, making benefits like Health FSAs unavailable on a pre-tax basis.
The IRS $600 rule refers to a change in reporting requirements for third-party payment apps (like Venmo, PayPal) for taxable income from goods and services, where platforms must send a Form 1099-K if you receive over $600 in a year, intended to capture gig economy/side hustle income, though delays and phased implementation have adjusted the timeline, with current rules for 2024 using a higher threshold ($5,000) before fully phasing to $600 for future years, but remember all taxable income, regardless of form, must always be reported.
To avoid the 22% tax bracket (or any higher bracket), focus on reducing your taxable income through strategies like maxing out 401(k)s and HSAs, deferring bonuses, tax-loss harvesting, smart charitable giving, and strategic asset location, understanding that higher rates only apply to income within that bracket, not your entire income.
Can I deduct 100% of my car expenses through my S Corp? You can only deduct the business-use percentage of your vehicle expenses. Personal use isn't deductible. If you use your car 80% for business, you can deduct 80% of actual expenses or claim 80% of your business miles at the standard rate.
Some key features of S corporations are: They do not pay federal income taxes. They're limited by the types of owners (shareholders) and cannot exceed 100 shareholders. A separate bank account and separate records are required with this form of business.
Forgetting to Set Aside Money for Taxes
One of the most common pitfalls for the self-employed is not reserving enough funds to cover their tax liabilities. Unlike traditional employment, taxes aren't automatically withheld for you. Failing to save for taxes can lead to financial strain when payment becomes due.
Many business expenses are 100% deductible, including advertising, employee wages, rent, supplies, and certain business meals like company parties or meals for the public, while personal deductions like student loan interest or charitable donations (depending on the type) can also be fully deductible for individuals. The key is that the expense must be "ordinary and necessary" for your trade or business or meet specific IRS criteria, often differentiating from the 50% rule for client meals.

The maximum credit amounts in 2025 range from $649 for those without children and up to $8,046 for those with three or more children. It might reduce your tax burden or result in a tax refund.
Note: The IRS won't object if your S Corp pays you nothing if your business is earning little to no income. However, when your S Corp starts making money, the first thing you need to do is pay yourself reasonable employee compensation. If there's money left over after that, you can pay yourself distributions.
An S corporation does have some potential disadvantages.
