S-corp election: the 2026 guide

What does an S-corp election do?

An S-corp election is a federal tax choice. Your company keeps its legal form, for example an LLC, but the IRS taxes it as an S corporation. The profit still flows to your personal return, so there is no second layer of corporate tax.

The change is in payroll tax. As a sole owner of a normal LLC, you pay self-employment tax on almost all of your profit: 12.4% for Social Security up to the yearly wage base, plus 2.9% for Medicare. As an S-corp owner who works in the business, you must pay yourself a reasonable W-2 salary. That salary carries payroll tax. The rest of the profit can come out as distributions, and distributions carry no payroll tax. For a side-by-side look at both setups, read LLC vs S corp.

Does an S-corp fit you? A checklist

It tends to fit when all of these are true:

• You have active business income: consulting, a practice, an agency, sales, co-hosting or management fees.
• Your profit is steady, not one good year. Look at the last 12 months and your plan for the next 12.
• Your profit is well above what you would have to pay someone else to do your job.
• You will run payroll on a schedule and keep business and personal money apart.
• Your state does not add a cost that wipes out the federal saving.

Who it does not fit:

• Passive rental owners. Rent on Schedule E does not carry self-employment tax, so the election adds cost with no payroll tax to save. Keep rentals in their own LLCs.
• Low or uneven profit. At $80,000 of profit the method below nets about $2,600 before payroll and tax prep fees, and fees can eat most of that.
• W-2 earners with a small side gig. If your salary is already over the Social Security wage base, the 12.4% piece is capped and the saving shrinks.
• Owners who want special splits. An S-corp allows one class of stock and no more than 100 eligible shareholders, with no nonresident aliens. A partnership is more flexible.

How much does an S-corp save? A worked table

This example is one owner, single filer, $150,000 of business profit, 2026 rules. To keep it readable it assumes a flat 24% income tax rate and the $16,100 standard deduction, and ignores state tax, health insurance and retirement plans. Without the election, the QBI deduction hits its cap of 20% of taxable income.

Same method at $80,000 of profit and a $45,000 salary: $4,419 of payroll tax saved, $1,812 of extra income tax, about $2,607 net before fees.

Three things to notice:

• The QBI deduction is 20% of business income, and your salary is not business income. So every dollar you move into salary cuts the deduction. That is why the net is smaller than the payroll tax line.
• A lower salary looks better on paper. It is also what the IRS looks for. The salary has to fit the work, not the tax result.
• Subtract your real added costs: a payroll service, the Form 1120-S return, and any state fee. Get quotes before you decide.

What is a reasonable salary for an S-corp owner?

There is no IRS percentage. The rule is that a shareholder who works in the business must get fair pay for that work before taking distributions. If the pay is too low, the IRS can treat distributions as wages and charge the back payroll tax, plus penalties and interest.

The IRS lists these factors: your training and experience, your duties, the time you put in, what similar businesses pay for similar work, and any pay agreements. It also asks where the money comes from: your own work, your staff, or the company's equipment and capital.

A simple way to set the number and defend it:

1. List the roles you do and the share of your time in each, for example 50% delivery, 30% sales, 20% management.
2. Price each role with public wage data for your area, such as the Bureau of Labor Statistics occupation tables. Save three to five dated sources.
3. Weight the prices by your time and adjust for part-time hours.
4. Write a one-page memo with the range and the number you picked. Review it each year and when your role or profit changes.

The "60/40 rule" you see online is a shortcut, not a rule. It can be too low for a solo professional who makes all the revenue and too high for an owner whose staff does the work.

When is the Form 2553 deadline?

File Form 2553 no more than 2 months and 15 days after the start of the tax year you want the election to take effect. You can also file at any time in the year before.

Practical points:

• Every shareholder signs the consent. A missing signature is a common reason for rejection.
• Form 2553 is filed on its own by fax or mail, as the instructions say. It is not attached to your return.
• An eligible LLC that files Form 2553 is treated as electing to be taxed as a corporation, so most owners do not also need Form 8832.
• Keep proof that you sent it and watch for the IRS acceptance letter. Call if it does not arrive.
• The Form 1120-S return date in March is a return deadline. It does not make a late election valid.

What if I missed the S-corp election deadline?

Rev. Proc. 2013-30 gives relief for late elections in many cases. You file Form 2553 within 3 years and 75 days of the date you wanted the election to start. Write "FILED PURSUANT TO REV. PROC. 2013-30" at the top.

The IRS instructions say the filing must show three things:

• The company meant to be an S corporation from that date.
• There was reasonable cause for filing late.
• The shareholders filed their returns as if the election was in place.

Relief depends on your facts. It is not automatic. Owners often find a missing election years later, during a loan, a sale or a new CPA's review. Fix it as soon as you find it.

What changes after you elect?

• Payroll. Pay yourself a W-2 salary on a regular schedule before you take distributions. Do not catch it up at year end.
• A new return. The company files Form 1120-S and gives each owner a Schedule K-1.
• Health insurance. For an owner with more than 2% of the shares, the company pays or reimburses the premiums and adds them to the W-2. The owner can then take the self-employed health insurance deduction.
• Retirement. Employer 401(k) contributions are based on your W-2 salary, not your distributions. A very low salary also limits what you can put away. The 2026 employee deferral limit is $24,500.
• Clean books. Keep wages, distributions, reimbursements and shareholder loans in separate accounts. Pay back business costs through an accountable plan. Track your basis so you know when a distribution is taxable.
• State rules. Some states charge S corporations their own tax or minimum fee, and a few cities do not honor the federal election. Check your state before you file.

Once the company is steady and profitable, some owners also look at captive insurance to cover business risks their regular policies leave out. That is a separate, advanced step. It needs real risks, fair premiums and close review.

What do our wealth plans show about S-corps?

Of the 61 anonymized wealth plans published on this site (inventory dated Sept 13, 2026), 29 discuss an S-corp election. It is one of the most common moves for clients who own a service business.

One published plan, Abraham's, models a switch from a C corporation to an S corporation and puts the yearly estimate at $42,000 to $53,000. That is the plan's estimate for his facts, not a filed result, and a C-corp switch has costs and timing rules of its own.

What the video covers.

• An LLC with $100,000 of profit pays self-employment tax on all of it. Preston rounds that to 15.3%, or $15,300.
• With an S-corp election and a $50,000 salary, payroll tax applies only to the salary, about $7,650.
• That $7,650 is the payroll piece only. The table below adds the QBI change and shows why the real saving is smaller.

What the video covers.

• A single-owner LLC is ignored for federal income tax by default. The profit lands on your return and carries self-employment tax.
• The S-corp election is the step that changes how the profit is taxed. The LLC stays an LLC under state law.
