What's the Difference Between an LLC and an S-Corp?

An LLC (Limited Liability Company) is a legal structure that protects your personal assets from business liabilities. By default, a single-member LLC is taxed as a sole proprietorship — all net profit flows to your personal return and is subject to self-employment tax (15.3% on the first $184,500 for tax year 2026, 2.9% above that).

An S-Corporation is a tax election, not a separate legal entity. An LLC can elect S-Corp taxation by filing Form 2553 with the IRS. Once elected, the owner splits income into two components: a W-2 salary and profit distributions. Self-employment tax applies only to the salary — not the distributions. That's where the savings come from.

As shown in the case study above: a business with $100,000 net profit pays $15,300 in SE taxes as an LLC. With an S-Corp election and a $50,000 reasonable salary, that drops to $7,650 — a savings of $7,650 per year.

When Does an S-Corp Election Make Sense?

The S-Corp election makes financial sense for most businesses once net profit consistently exceeds $80,000 to $100,000 per year. Below that level, the administrative costs may outweigh the tax savings. Above it, the math typically works strongly in your favor.

A business with $100,000 in net profit can save $7,650 per year in self-employment taxes. At $200,000, annual savings typically exceed $10,000. At $300,000 or more, savings can reach $15,000 to $20,000 — every single year.


The Catch: Reasonable Compensation

The IRS requires S-Corp owner-employees to pay themselves a "reasonable salary" — compensation that reflects what they'd earn doing the same work elsewhere. You cannot pay yourself $1 in salary and take the rest as distributions. The IRS has successfully challenged this in tax court many times.

Getting this number right is one of the most important parts of the S-Corp election. It needs to be defensible to the IRS while still being optimized for tax savings — which is exactly the analysis our tax planning team performs for every client making the switch.


Additional Costs of an S-Corp to Factor In

  • Payroll setup and processing — you must run payroll for yourself as a W-2 employee, including quarterly tax deposits
  • Separate S-Corp tax return — Form 1120-S is filed in addition to your personal return, typically increasing CPA fees
  • Maryland PTE tax — Maryland's pass-through entity election interacts with the S-Corp structure and requires separate analysis
  • Stricter recordkeeping — S-Corps require cleaner separation of business and personal finances

For most businesses above the income threshold, these costs are modest compared to the tax savings — but they should be factored into the decision.

Timing the S-Corp Election: Deadlines Matter

To elect S-Corp status for the current tax year, Form 2553 must generally be filed by March 15 of that year for calendar-year businesses. Late elections are sometimes granted but require a reasonable cause explanation.

For new businesses, the election can be made at formation or within 75 days of the business start date to be effective for the first year. Every year in the wrong structure is money you can't recover.


Maryland PTE Tax, S-Corps & the One Big Beautiful Bill: What Changed in 2026

Maryland offers a Pass-Through Entity (PTE) tax election that allows S-Corps and partnerships to pay Maryland income tax at the entity level. This has long been valuable because it generates a federal deduction that bypasses the SALT cap — effectively letting Maryland business owners deduct more than the individual SALT limit allows.

Important 2025 update: The One Big Beautiful Bill Act, signed into law on July 4, 2025, raised the federal SALT deduction cap from $10,000 to $40,000 for tax years 2025 through 2029 (for taxpayers with income under $500,000). This is a major change — and good news is that the final bill did not eliminate or restrict the PTE workaround for S-Corps, which some earlier versions proposed.

For Maryland S-Corp owners in 2026, this means you can potentially benefit from both the higher $40,000 SALT cap on your personal return and the PTE election at the entity level — depending on your income and situation. This requires careful coordination between your federal and Maryland filings, which our tax planning team handles as part of every S-Corp engagement.


Is an S-Corp Right for Your Maryland Business?

The S-Corp election typically makes sense if most of these apply to you:

Net profit is consistently over $80,000 per year
You can pay yourself a reasonable W-2 salary
You plan to stay in business for at least 3 more years
Business has been profitable for 2 or more years
You want to reduce self-employment taxes
You haven't spoken to a CPA about your structure yet

If 3 or more of these apply, it's worth a conversation. We'll run your actual numbers and give you a clear answer — no obligation.

S-Corp vs LLC: Frequently Asked Questions

At what income level does an S-Corp election start to make sense?

Most businesses see the S-Corp election make financial sense once net profit consistently exceeds $80,000 to $100,000 per year. Below that level, the added payroll and filing costs often outweigh the self-employment tax savings.

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

A reasonable salary should reflect what you'd pay someone else to do the same work in your role and industry. The IRS has successfully challenged S-Corp owners who pay themselves an unreasonably low salary to maximize distributions, so this figure needs to be defensible, not just tax-optimized.

Does an S-Corp election change my liability protection?

No. An S-Corp is a tax election, not a separate legal entity, so it doesn't change the liability protection you already have through your LLC. The personal asset protection stays the same; only the tax treatment of your income changes.

Can I make the S-Corp election for this year, or do I have to wait?

To elect S-Corp status for the current tax year, Form 2553 generally needs to be filed by March 15 for calendar-year businesses. New businesses can elect at formation or within 75 days of starting to be effective for their first year.

Does the S-Corp election interact with Maryland's PTE tax?

Yes. Maryland's Pass-Through Entity tax election allows S-Corps to pay Maryland income tax at the entity level, which can generate a federal deduction that bypasses the SALT cap. Coordinating the S-Corp election with the PTE election requires careful planning specific to your situation.
