NEW YORK — Sit down at a kitchen table anywhere from Manhattan and Westchester to Bergen County, Fairfield County, or Back Bay Boston, and one financial question quickly dominates the conversation around llc vs. s-corp & ny ptet tax calculator (2026): How do the 2026 statutory rules, interest rates, and regional tax brackets actually translate into real dollars for your household or business? In a default Single-Member LLC or partnership, 100% of net business profit is subject to the 15.3% Federal Self-Employment tax up to the $176,100 Social Security cap, plus 2.9%–3.8% Medicare tax on every dollar above it.
LLC vs. S-Corp Self-Employment & NY PTET Tax Savings Calculator
Compares single-member LLC self-employment tax (15.3%) against an S-Corp reasonable salary split plus the New York Pass-Through Entity Tax (PTET) federal SALT bypass.
How the NYS Pass-Through Entity Tax (PTET) Bypasses the SALT Cap?
Since the Tax Cuts and Jobs Act limited individual State and Local Tax (SALT) itemized deductions on Schedule A, business owners in New York, New Jersey, Connecticut, and Massachusetts lost the ability to deduct tens of thousands of dollars in state income taxes. In response, New York enacted Article 24-A (Pass-Through Entity Tax), explicitly blessed by the IRS in Notice 2020-75.
When an eligible multi-member LLC, partnership, or New York S-Corporation opts into NYS PTET (annual election due March 15 via the NYS Business Online Services portal), the entity pays the state tax directly (6.85% to 10.90%) and deducts it as an ordinary business expense under IRC § 164, reducing federal pass-through K-1 income dollar-for-dollar. The owner then claims a 100% dollar-for-dollar refundable credit on Form IT-653 against their personal NY State tax bill.

Let’s Run the Numbers in Dollars: Comparing Payroll / Self-Employment FICA vs. Federal Tax Saved via PTET Deduction in the Tri-State Corridor
Let’s run the numbers in dollars using verified 2026 benchmarks from our quantitative table above so you can see the exact gap before making a decision:
- Baseline Profile (Tax Component: Payroll / Self-Employment FICA): Produces a verified outcome of $20,760 (S-Corp Operating in NYC (5 Boroughs)), reflecting $28,390 and $20,760.
- Scaled Tri-State Profile (Tax Component: Federal Tax Saved via PTET Deduction): Shifts the net figure to -$7,672 (S-Corp Operating in NYC (5 Boroughs)). Electing S-Corporation status (IRS Form 2553) splits profit into a ‘Reasonable W-2 Salary’ (subject to FICA) and Shareholder Distributions (exempt from the 2.9%–3.8% Medicare payroll tax), saving $6,000 to $22,000+ annually.
How Does The New York City 8.85% GCT Trap for S-Corporations Impact Your Bottom Line?
While an S-Corporation is a no-brainer for consultants, medical practices, and agencies in Westchester, Long Island, or New Jersey, New York City never conformed to the federal Subchapter S regime. Inside the five boroughs, an S-Corporation is taxed as a traditional C-Corporation under the NYC General Corporation Tax (GCT) at 8.85% of net income (or alternative salary-addback calculation)—and unlike NYS PTET, the 8.85% GCT does not generate a credit against your personal NYC 3.876% resident income tax.

Frequently Asked Questions
Can a Single-Member LLC without an S-Corp election opt into New York PTET?
No. A disregarded Single-Member LLC (filing on Schedule C) is not eligible for NYS PTET. To unlock NYS PTET as a solo founder, you must either file Form 2553 to elect S-Corporation status (plus NY Form CT-6) or add a bona fide second partner to file Form 1065 as a partnership.
What is the deadline to elect into NYS PTET for the current tax year?
The annual NYS PTET and NYC PTET election must be submitted online by March 15 of the tax year for calendar-year entities, with four mandatory quarterly estimated payments due March 15, June 15, September 15, and December 15.
