LLC vs S-Corp: Which Is Right for Your Business in 2026?
Most founders assume LLC and S-Corp are two types of business entity. They are not. One is a legal structure. The other is a tax election. This guide explains exactly what each is, shows the tax math for when the S-Corp election saves you money, and tells you when it is worth making the switch.
An LLC is a legal business entity you register with your state. An S-Corp is not a business entity at all. It is a federal tax classification you elect with the IRS. When most founders search "LLC vs S-Corp," they are asking whether to keep their LLC taxed the default way or elect S-Corp tax treatment to reduce self-employment taxes. The S-Corp election lets you split income into a salary and owner distributions, so you only pay self-employment tax on the salary portion. It makes financial sense when your business earns roughly $40,000 to $80,000 or more in net profit after your salary. Below that threshold, the payroll and accounting compliance costs of S-Corp status typically wipe out the savings. Form an LLC first. Revisit the S-Corp election once profits are consistently in that range.

This guide provides general educational information about business entities and tax elections. It is not legal or tax advice. Tax laws and state regulations vary. Consult a qualified CPA or tax attorney before making entity structure or S-Corp election decisions for your specific situation.
The LLC vs S-Corp question trips up almost every founder who hits a certain revenue milestone, and it trips them up for the same reason every time. They think they are comparing two types of business entity. They are not. An LLC is a legal structure registered with your state. An S-Corp is a tax election filed with the IRS. They live on completely different axes, which means the question "should I have an LLC or an S-Corp" is a bit like asking "should I buy a house or paint it blue." One does not replace the other. If you have been wondering whether to switch from an LLC to an S-Corp, this guide will clear up that framing in the first section and then answer the actual question you are trying to ask.
What most founders really want to know is simpler: should I keep my LLC taxed the default way, or should I elect S-Corp tax treatment with the IRS? That is a much more answerable question, and it has a clear, math-based answer. The S-Corp election reduces self-employment taxes by splitting your income into two buckets. But it also adds payroll obligations that cost real money and real time to maintain. Whether the election makes sense depends on your profit level, and there is a threshold where it starts to pay off.
What an LLC and S-Corp Actually Are
Before the comparison can make sense, you need to separate two concepts that most people confuse: legal entity types and tax classifications. They are different systems entirely.
What an LLC is
An LLC is a business entity type. It is a legal structure you create by filing Articles of Organization with your state's Secretary of State office and paying a filing fee. Once formed, the LLC exists as a separate legal entity from you. It can sign contracts, own assets, open bank accounts, and in most situations protect your personal assets from business liabilities. The protection question is covered in full in our guide on LLC vs sole proprietorship, if that is still an open question for you.
By default, a single-member LLC is taxed as a sole proprietorship, and a multi-member LLC is taxed as a partnership. Both are pass-through structures, meaning business income flows directly to your personal tax return. But that tax treatment is not fixed. The LLC entity form is flexible on purpose, and the S-Corp election is one of the options.
What an S-Corp is
When an LLC elects S-Corp tax treatment, the business entity itself does not change. You still have an LLC registered with your state. Your operating agreement, your liability protection, your contracts with clients, none of that changes. The only thing that changes is how the IRS treats your income for tax purposes. An S-Corp is not something you form. It is something you elect.
The cleaner way to think about it
An LLC can be taxed as a sole proprietorship (single-member default), a partnership (multi-member default), a C-Corp, or an S-Corp. When you elect S-Corp status, you have an LLC that is taxed as an S-Corp. The entity type and the tax treatment are two separate choices that happen to overlap.
How the Taxes Work Differently
The only reason most founders consider the S-Corp election is to reduce self-employment taxes. Here is exactly how the math works, without the jargon.
Default LLC taxation
On $100,000 in net profit as a default LLC, your self-employment tax is roughly $15,300 before you pay a dollar in income tax. That is not a typo. It comes right off the top.
S-Corp taxation
When your LLC elects S-Corp tax treatment, the income structure changes. Instead of all profit being subject to self-employment tax, you pay yourself a reasonable salary and take the remaining profits as owner distributions. Only the salary is subject to payroll taxes (the S-Corp equivalent of self-employment tax). Distributions are not.
The tax math on $100,000 net profit
Default LLC
LLC with S-Corp election
Estimated annual savings from S-Corp election: $6,120 on $100,000 net profit
The important caveat: you have to pay yourself a "reasonable salary" before you can take distributions. The IRS does not publish a specific formula, but it expects what you would pay a third party to do your job at market rates. If you run a consulting business generating $100,000 in revenue, a salary of $60,000 to $70,000 is a defensible starting point. Paying yourself $1 in salary and taking $99,999 in distributions is not going to fly. The IRS actively audits S-Corps with unreasonably low officer compensation, and it can reclassify distributions as wages if the salary is deemed inadequate.
The Payroll Requirement No One Warns You About
The S-Corp election does not just change a number on your tax return. It changes how you pay yourself and how much administrative overhead you are signing up for, and this is the detail most articles gloss over before getting to the savings calculation.
When you elect S-Corp status, you become an employee of your own business. That means you must run a formal payroll. Specifically, you are required to:
Use a payroll provider to run your salary. Services like Gusto, ADP, or Patriot Payroll handle this automatically, but they cost money. Expect to pay $50 to $150 per month for a single employee setup.
File quarterly payroll tax returns (IRS Form 941) on time, every quarter, four times a year. Missing a deadline triggers penalties that can eat into your savings.
Issue yourself a W-2 at year end and file IRS Form 1120-S (the S-Corp annual income tax return) in addition to your personal 1040. This is a separate tax return that most accountants charge extra to prepare.
Maintain strict separation between business and personal finances, the same discipline required for all LLCs. Mixing funds can pierce your liability protection regardless of the tax election.
The real annual cost of S-Corp status
Payroll software runs approximately $600 to $1,800 per year for a single-employee setup. The additional accountant fee for preparing Form 1120-S typically runs $500 to $2,000 per year depending on complexity. Add those together and you are looking at roughly $1,100 to $3,800 per year in compliance overhead before the election saves you a single dollar. Your tax savings need to exceed this number to make the election worthwhile.

When the S-Corp Election Actually Makes Sense
The S-Corp election is a pure math problem. The only question is whether your annual tax savings exceed your annual compliance costs. Here is how to run the numbers yourself before you pay an accountant to run them for you.
The calculation in plain terms
Your SE tax savings equal 15.3% multiplied by the portion of profit you shift from self-employment income to S-Corp distributions. If your net profit is $120,000 and you pay yourself a $70,000 salary, the distributions are $50,000. Your SE tax savings are roughly $7,650 on those distributions.
If your payroll software costs $900 per year and your accountant charges $1,500 extra for the S-Corp return, your compliance overhead is $2,400. Your net benefit is $7,650 minus $2,400, which is $5,250 per year. Worth it.
If your net profit is $35,000 and you pay yourself a $30,000 salary, your distributions are only $5,000. Your SE tax savings are $765. That does not cover compliance costs. Not worth it.

Wait for consistent profitabilityTwo factors that can shift the math: your state's treatment of S-Corps, and whether you handle payroll yourself. Some states do not recognize S-Corp elections or add their own franchise taxes on S-Corp income that reduce the net benefit. California, for example, adds a 1.5% franchise tax on S-Corp net income. Check IRS.gov for federal S-Corp eligibility rules and confirm your state's specific treatment with a local CPA before electing.
One more thing worth knowing: your business needs to be consistently profitable before the election makes sense. If your revenue varies sharply from year to year, the payroll obligation becomes a liability during low-revenue periods. The salary is mandatory regardless of whether you had a great quarter or a slow one. This is why founders who are tracking the right key performance indicators for their business are usually the ones who time this decision well.
How to Elect S-Corp Status
If the numbers check out and you are ready to make the election, the process is straightforward. You do not need an attorney for this step, though working with a CPA for the first year is money well spent.
Confirm your LLC is eligible
Your LLC must be a domestic entity with no more than 100 members, all of whom are US citizens or resident aliens. LLCs with non-US members, other business entities as members, or multiple classes of membership interest do not qualify.
File IRS Form 2553
Complete Form 2553 and mail or fax it to the IRS. The form asks for basic LLC information, the desired election effective date, and signatures from all members. You can download it directly from IRS.gov. Keep a copy and request a written confirmation of the election from the IRS.
Set up payroll before paying yourself anything
Once the election is approved, you must run formal payroll from the election date forward. Choose a payroll provider, establish your reasonable salary, and begin payroll before taking any owner payments. The IRS can revoke S-Corp status if you fail to pay yourself a salary while taking distributions.
Work with a CPA experienced in S-Corps for the first year
The first year of S-Corp filing involves Form 1120-S, quarterly 941 payroll tax filings, W-2 preparation, and the reasonable salary determination. Errors in any of these can trigger penalties or an audit. Getting your business budget dialed in around the new compliance costs before you elect is a smart move.
Do this before you call your accountant. Pull your last 12 months of net profit. Subtract what you would reasonably pay yourself as an employee in your industry. Whatever remains is the distribution pool. Multiply it by 0.153 to estimate your annual SE tax savings. Then get a payroll software quote and ask your accountant what they charge for an S-Corp return. If savings exceed costs by at least $1,500, the election is worth making. If not, put it on your calendar to revisit when revenue hits the next threshold. Keeping a clean view of your cash flow is what makes this kind of decision clear instead of stressful.
