The NYC Business Puzzle

LLC vs. S-Corporation: A Data-Driven Decision

The optimal business structure in New York City is not a simple choice—it's a strategic decision that depends entirely on your profit level. This analysis reveals the precise point where the best choice flips.

Why NYC is Different: The Dual Profit Puzzle

The most critical concept in any NYC tax analysis is that your business has two different profit figures: a lower one for federal taxes and a higher one for city taxes. This is due to a state tax strategy called the Pass-Through Entity Tax (PTET).

The $175,500 Crossover Point

This chart visualizes the total annual tax cost for an LLC versus an S-Corp across different profit levels. The point where the lines cross is the financial break-even point where the strategic advantage flips from one entity to the other.

Your 2025 Projection at $162,037 Profit

At your current profit level, the S-Corporation holds a modest advantage. The FICA tax savings are just enough to overcome the higher NYC tax burden. Here's how the total tax costs break down.

Deep Dive: The PTET & SALT Cap Workaround

The "Dual Profit" situation exists because of a beneficial tax strategy. It's not a penalty, but a solution to the federal $10,000 State and Local Tax (SALT) cap. Both LLCs and S-Corps can use it.

1. The Problem

The $10,000 federal SALT cap limits your personal deduction for state taxes.

2. The Solution: PTET

The LLC pays your state tax for you, making it a fully deductible business expense.

3. The Federal Effect

This deduction lowers your federal profit, saving you federal tax.

4. The NYC Effect

NYC requires this deduction to be "added back," creating a higher city profit base.

This strategy is beneficial regardless of your entity choice. It reduces your federal tax bill while being neutral for city tax purposes.

Common Question: What is "Reasonable Compensation"?

For an S-Corp, the IRS requires you to pay yourself a "reasonable" salary for the work you perform. This is the most critical compliance risk for S-Corps.

The S-Corp Strategy

The goal is to pay a salary that is high enough to be defensible to the IRS, but low enough to maximize payroll tax savings on the remaining profit, which is taken as a distribution.

The Risk

Setting a salary too low is a major audit red flag. If challenged, the IRS can reclassify your distributions as wages and assess back taxes, penalties, and interest. The 40% salary used in this analysis is often defensible but requires documentation.

The Consistent Advantage: The QBI Deduction

The 20% Qualified Business Income (QBI) deduction is a powerful federal tax break. While both structures benefit, the LLC always gets a larger tax shield.

Your Strategic Roadmap

1

Analyze Your 2025 Profit Projection

Your decision hinges on your expected growth. Do you anticipate your federal profit staying below or growing beyond the ~$175.5k crossover point?

2

If Profit Stays Below $175.5k

The **S-Corporation (at 40% salary)** is the most tax-efficient choice. The modest tax savings (~$1,228) should be weighed against the real-world costs of S-Corp compliance (payroll, corporate filings). To elect this for 2026, you must file Form 2553 by March 15, 2026.

3

If Profit Grows Above $175.5k

The **LLC** becomes the clear winner, with savings growing dramatically as profit increases. Remaining an LLC avoids the cost and complexity of converting to an S-Corp, only to find it's no longer the optimal choice.

This analysis is a snapshot. An annual review is critical to ensure your business structure remains optimal as tax laws and your profits change.
