S-Corp, LLC, or Sole Proprietor? What NYC Business Owners Need to Know

Choosing the right business structure is one of the most important tax decisions you will make. Here is how to think through it for a New York City business.

This question comes up in almost every conversation we have with new or growing business owners in New York City. The structure you choose affects your taxes, your legal liability, your paperwork burden, and your flexibility. There is no one right answer — it depends on your situation — but here is how to think through it clearly.

Starting with the simplest option: a sole proprietorship. This is the default if you are doing business as an individual without forming any entity. There is no registration required, no separate tax return, and minimal paperwork. Your business income flows directly onto your personal tax return on Schedule C.

The downside is that you pay self-employment tax — 15.3% — on all of your net profit. On $100,000 of profit, that is $15,300 just in self-employment tax before any income tax. There is also no liability protection, meaning your personal assets are at risk if something goes wrong in the business.

An LLC, which stands for Limited Liability Company, gives you legal protection without changing your taxes much by default. A single-member LLC is taxed exactly like a sole proprietorship — the same Schedule C, the same self-employment tax. The benefit is liability protection. Your personal assets are separated from your business assets. For New York City residents, there is also an LLC filing fee that ranges from $25 to $4,500 per year depending on income, which is worth factoring in.

The S-Corporation election is where things get interesting from a tax perspective. An S-Corp is not a separate entity type — it is a tax election that an LLC or corporation can make. The key benefit is that it can reduce self-employment taxes significantly.

Here is how: with an S-Corp, you pay yourself a reasonable salary and that salary is subject to payroll taxes. But profits above your salary are distributed to you as an owner distribution, and those distributions are not subject to self-employment tax. If your business earns $150,000 and you pay yourself a reasonable salary of $80,000, you save self-employment taxes on the remaining $70,000. At 15.3%, that is over $10,000 in savings.

The tradeoff is complexity. An S-Corp requires payroll, a separate business bank account, more formal bookkeeping, and an additional tax return. The cost of administering the structure properly typically runs $1,500 to $3,000 per year in accounting fees. The math only makes sense once your profit is high enough that the tax savings exceed those costs — generally somewhere around $50,000 to $60,000 in annual profit.

For New York City specifically, there is an additional consideration: the NYC Unincorporated Business Tax. This 4% tax applies to income from unincorporated businesses allocated to NYC. It applies to sole proprietors and partnerships but not to S-Corps. For profitable NYC businesses, this is another factor that can tip the analysis toward an S-Corp election.

The right answer for your situation depends on your profit level, your risk tolerance for liability, how much administrative complexity you can handle, and what your growth trajectory looks like. A conversation with a tax professional who knows New York City business taxation is the best way to get a tailored recommendation.
