This One Decision Could Save You $15,000 or More

You work hard to grow your online business. But are you keeping the money you earn?

If you sell on Amazon, Shopify, Etsy, or eBay, you might be paying too much in taxes. The fix? It’s called an S-Corp election.

This guide will show you how it works. We’ll use real numbers. And we’ll help you decide if it’s right for you.

The Hidden Tax That’s Eating Your Profits

Right now, you probably run your business as a sole proprietor or LLC. That means you pay self-employment tax on every dollar of profit.

How much is that tax? 15.3%.

Here’s where that number comes from:

• Social Security: 12.4% on income up to $184,500 in 2026
• Medicare: 2.9% on all income (no limit)

Let’s say your business makes $150,000 in profit. As a sole proprietor, you pay about $21,195 in self-employment tax. That’s on top of your regular income tax.

That’s a lot of money. But there’s a legal way to cut that bill in half.

What Is an S-Corp?

An S-Corp is not a new business type. It’s a tax choice you make with the IRS.

When you elect S-Corp status, you split your income into two parts:

1. A salary you pay yourself (this gets taxed at 15.3%)
2. The rest as profit (this does NOT get hit with that 15.3% tax)

The key? Only your salary gets hit with the 15.3% tax. The profit you take out? It skips that tax entirely.

See the Savings: A Real Example

Let’s look at an Amazon FBA seller who makes $150,000 in profit.

That’s $10,485 back in your pocket. Every single year.

If your profit is higher? The savings grow. At $200,000 profit, you could save $15,000 or more.

Is S-Corp Right for You?

S-Corp works best when you meet these conditions:

S-Corp is a good fit if…

• Your business profit is $60,000 or more per year
• You expect to stay profitable
• You can handle some extra paperwork (or hire help)
• You want to save for retirement (S-Corp + Solo 401(k) is powerful)

S-Corp may NOT be right if…

• Your profit is under $50,000
• Your income goes up and down a lot
• You plan to raise money from investors
• You expect to lose money next year

The Magic Number

Most CPAs agree: S-Corp starts making sense when profit hits $60,000 to $80,000. Below that, the extra costs eat up your savings.

Extra costs include: payroll service ($600–$1,500/year), extra tax filing ($1,000–$2,500/year), and bookkeeping time.

The Deadline You Can’t Miss

Want S-Corp status for all of 2026? You must file IRS Form 2553 by March 16, 2026.

(March 15 falls on a Sunday, so the deadline moves to Monday.)

But here’s the thing: You should decide before January 1, 2026. Why? Because you need to set up payroll from day one. Fixing things later is messy and expensive.

The #1 Rule: Pay Yourself a Fair Salary

The IRS has one big rule for S-Corps: You must pay yourself a “reasonable” salary.

What does “reasonable” mean? It’s what someone else would pay you to do the same job.

If you pay yourself too little, the IRS can:

• Reclassify your profits as wages
• Charge you back taxes
• Add penalties up to 100% of what you owe

How to Pick the Right Salary

There’s no magic formula. But here are some guidelines based on how much you work in your business:

Important: These are just starting points. You must document why your salary makes sense. Use data from Salary.com, Glassdoor, or the Bureau of Labor Statistics.

How to Make the Switch: 5 Simple Steps

Step 1: Form an LLC (if you don’t have one)

You can’t elect S-Corp as a sole proprietor. File with your state’s Secretary of State first.

Step 2: Get an EIN from the IRS

Go to IRS.gov. It’s free and takes 5 minutes online.

Step 3: File Form 2553

This is the form that tells the IRS you want S-Corp status. Mail or fax it—you can’t e-file. All owners must sign.

Step 4: Set up payroll

Use Gusto, ADP, or QuickBooks Payroll. You need real paychecks with taxes withheld. This is not optional.

Step 5: Check your state rules

Some states have extra steps:

• California: $800/year minimum tax + 1.5% of net income
• New York: File Form CT-6 for state recognition
• Texas: No income tax, but franchise tax applies

Bonus: The 20% Deduction You Might Get

S-Corp owners can also get the Qualified Business Income (QBI) deduction. This lets you deduct up to 20% of your business profits from your taxes.

Good news: The One Big Beautiful Bill Act made this deduction permanent in 2025. It’s not going away.

In our $150,000 example, the $80,000 distribution could get you a $16,000 deduction. That’s another $3,500+ in savings at the 22% tax bracket.
