New York Estimated Tax Payments 2026: Due Dates, Calculations, and MCTMT

Published: March 24, 2026 Tax Year: 2026

A Message from Slava

When I was building Anna Money in London, UK tax obligations for the self-employed were relatively manageable — self-assessment, VAT, National Insurance. Then I moved to New York to build Jupid, and discovered that self-employed people here can face three separate layers of estimated tax payments: federal, New York State, and New York City.

And then there's the MCTMT — the Metropolitan Commuter Transportation Mobility Tax. Most self-employed people working in the MTA district have never heard of it. But if your net self-employment earnings exceed $50,000 and you work in New York City or the surrounding commuter counties, you owe it. Quarterly. On top of everything else.

New York is one of the highest-tax states for self-employed individuals. Between the state income tax (up to 10.90%), NYC income tax (up to 3.876%), federal income tax, self-employment tax, and MCTMT, your total marginal rate can exceed 55%. That makes getting your estimated payments right especially important — underpay, and the penalties stack across every level of government.

This guide breaks down every New York estimated tax obligation for 2026: who owes what, when it's due, how to calculate it, and how to avoid penalties. If you operate a business in New York, bookmark this page.

New York State Estimated Tax Payments

Who Must Pay

You must make New York State estimated tax payments if you expect to owe more than $300 in New York State income tax for the year after subtracting credits and withholding. This threshold is lower than the federal $1,000 threshold — a detail many New York taxpayers miss.

This applies to:

• Self-employed individuals and freelancers
• Partners and S-Corp shareholders with pass-through income
• Individuals with significant investment income not subject to withholding
• Nonresidents with New York-source income

2026 Quarterly Due Dates

Safe Harbor Rules

New York's safe harbor rules for avoiding underpayment penalties:

If your prior-year New York AGI was $150,000 or less:

• Pay at least 100% of your prior year New York tax liability, or
• Pay at least 90% of your current year New York tax liability

If your prior-year New York AGI exceeded $150,000:

• Pay at least 110% of your prior year New York tax liability, or
• Pay at least 90% of your current year New York tax liability

How to Pay

New York State estimated tax payments are made through the New York Department of Taxation and Finance (DTF):

• Online Services at tax.ny.gov — free bank transfer (ACH debit)
• Form IT-2105 — Estimated Tax Payment Voucher (if paying by mail)
• Credit card — through third-party processors (convenience fees apply)

NYC Estimated Tax Payments

Who Must Pay

If you are a resident of New York City, you owe NYC income tax in addition to New York State income tax. There is no separate $300 threshold for NYC — if you owe NYC income tax after withholding and credits, you must make estimated payments.

NYC income tax applies only to residents of the five boroughs. If you live outside NYC, you do not owe city income tax (though you may owe MCTMT — see below).

NYC Tax Rates (2026)

The top rate of 3.876% applies to most self-employed NYC residents.

Payment Dates and Method

NYC estimated tax payments follow the same quarterly schedule as New York State:

• April 15, 2026 — Q1
• June 15, 2026 — Q2
• September 15, 2026 — Q3
• January 15, 2027 — Q4

NYC estimated taxes are paid together with your New York State estimated taxes on Form IT-2105. You do not file a separate NYC payment voucher — the single form covers both state and city.

MCTMT for Self-Employed Individuals

What Is the MCTMT?

The Metropolitan Commuter Transportation Mobility Tax (MCTMT) is a tax that funds the MTA (Metropolitan Transportation Authority). For self-employed individuals, it applies to net self-employment earnings that exceed $50,000 per year.

The MCTMT rate for self-employed individuals is 0.34% of net self-employment earnings.

Who Owes It

You owe MCTMT if all three of these conditions are met:

1. You have net self-employment earnings exceeding $50,000 for the tax year
2. You are self-employed (or a member of a partnership) carrying on a trade or business within the MTA district
3. Your business activity takes place in one or more of the following counties:

MTA District Counties:

• New York (Manhattan)
• Kings (Brooklyn)
• Queens
• Bronx
• Richmond (Staten Island)
• Rockland
• Nassau
• Suffolk
• Orange
• Putnam
• Dutchess
• Westchester

How to Calculate

The calculation is straightforward:

MCTMT = Net self-employment earnings × 0.34%

For example, if your net Schedule C income is $120,000:

• MCTMT = $120,000 × 0.0034 = $408 per year
• Quarterly payment = $408 ÷ 4 = $102 per quarter

The $50,000 threshold is a cliff, not an exclusion. Once you exceed $50,000, the 0.34% rate applies to your entire net self-employment earnings — not just the amount above $50,000.

Payment Dates

MCTMT quarterly payments follow the same schedule: April 15, June 15, September 15, and January 15. Report estimated payments on Form MTA-6 and reconcile on your annual return using Form IT-360.1 as part of IT-201.

New York Business Entity Returns

S-Corporations

Form: CT-3-S (New York S Corporation Franchise Tax Return) or CT-34-SH (if an election under Tax Law Article 22 applies) Original deadline: March 15, 2026 (March 16, 2026, since March 15 is a Sunday) Extended deadline: September 15, 2026

New York S-Corps are subject to a fixed dollar minimum tax based on New York receipts, ranging from $25 to $4,500. S-Corp shareholders report their share of income on their personal New York returns (IT-201 or IT-203).

Partnerships

Form: IT-204 (Partnership Return) Original deadline: March 15, 2026 (March 16, 2026) Extended deadline: September 15, 2026

Partnerships with New York-source income must file IT-204 and issue NY K-1s to partners for use on their individual returns.

C-Corporations

Form: CT-3 (General Business Corporation Franchise Tax Return) or CT-4 (for eligible small corporations) Original deadline: Varies by fiscal year. Calendar-year C-Corps file by April 15, 2026. Extended deadline: Six months from the original due date

New York C-Corps are subject to franchise tax calculated under three bases — the business income base, the capital base, and the fixed dollar minimum — and pay whichever produces the highest tax.

LLCs

New York LLC filing depends on federal tax treatment: single-member LLCs report on IT-201, multi-member LLCs file IT-204, S-Corp-electing LLCs file CT-3-S, and C-Corp-electing LLCs file CT-3.

All New York LLCs also owe an annual filing fee based on New York-source gross income, ranging from $25 (income under $100,000) to $4,500 (income of $25 million or more). This is separate from income tax.

New York Pass-Through Entity Tax (PTET)

What Is PTET?

New York's Pass-Through Entity Tax is an optional election that allows partnerships, S-Corps, and LLCs taxed as partnerships or S-Corps to pay state income tax at the entity level. This was created as a workaround to the federal $10,000 SALT deduction cap — the entity-level tax is deductible as a business expense on the federal return, effectively bypassing the SALT cap for pass-through owners.

PTET Rates (2026)

Election and Payment Deadlines

• Election deadline: March 15 of the tax year (must be made annually)
• Estimated payments: Quarterly on the same schedule (April 15, June 15, September 15, January 15)
• Annual return: Due March 15 of the following year

Partners and shareholders receive a refundable credit on their personal New York returns for their share of PTET paid.

New York Estimated Tax Penalty

How It Works

If you fail to pay enough estimated tax by any quarterly due date, New York imposes a penalty based on the underpayment amount, the applicable interest rate (set quarterly by NY DTF), and the number of days outstanding. The penalty is calculated separately for each quarter — overpaying in a later quarter does not eliminate a prior-quarter penalty.

How to Avoid the Penalty

You will not owe a New York estimated tax penalty if:

• Your total tax after credits and withholding is $300 or less
• You paid at least 90% of the current year's tax through estimated payments and withholding
• You paid at least 100% of the prior year's tax (110% if prior-year NY AGI exceeded $150,000)
• You used the annualized income installment method (for taxpayers with uneven income throughout the year) and met the requirements for each quarter

Penalty Form

If you owe an underpayment penalty, you calculate it on Form IT-2105.9 (Underpayment of Estimated Tax by Individuals and Fiduciaries) and file it with your annual return.

Combined Tax Example: Self-Employed NYC Resident

To illustrate the total estimated tax burden, here's an example for a single, self-employed NYC resident with $150,000 in net Schedule C income and no other income sources.

Annual Tax Calculation

Quarterly Estimated Payments

This example uses 2026 rates and the standard deduction. Your actual amounts will vary based on deductions, credits, filing status, and other income. Use the Quarterly Tax Calculator to estimate your specific payments. For a full breakdown of federal quarterly obligations, see our Quarterly Estimated Taxes Guide.

The effective total tax rate on $150,000 of self-employment income in this example is approximately 37.6% — before accounting for any business deductions beyond the standard deduction and QBI.

---

Filing Extensions

New York automatically extends your state filing deadline when you file a federal extension (Form 4868). You do not need to file a separate New York extension form. If you file Form 4868 with the IRS by April 15, your New York return (IT-201 or IT-203) deadline extends to October 15.

However, this does not extend the deadline to pay. If you expect to owe New York taxes, you must still pay by April 15 using Form IT-370 to remit payment with your extension request. Interest accrues from April 15 on any unpaid balance. Quarterly estimated payment due dates remain unchanged regardless of filing extensions.

Common Mistakes

1. Forgetting NYC Estimated Payments on Top of NY State

New York City residents owe both state and city estimated taxes. Some taxpayers calculate their New York State obligation and forget that NYC adds another 3.078%–3.876% on top. For a self-employed NYC resident earning $150,000, that oversight could mean underpaying by roughly $5,000 for the year.

2. Not Knowing About the MCTMT

The Metropolitan Commuter Transportation Mobility Tax catches many self-employed individuals off guard. If you earn more than $50,000 in net self-employment income and work anywhere in the 12-county MTA district, you owe quarterly MCTMT payments. It's a relatively small amount (0.34%), but failing to pay it triggers penalties and interest.

3. Applying Federal Safe Harbor Rules to New York

The federal estimated tax threshold is $1,000 — you must make estimated payments if you expect to owe $1,000 or more after withholding and credits. New York's threshold is only $300. Taxpayers who calculate their estimated obligation at $500 and assume they're below the threshold (using the federal number) still owe New York estimated payments and will face an underpayment penalty.

4. Not Paying NY Estimated Tax When Filing a Federal Extension

Filing Form 4868 gives you more time to file both your federal and New York returns. But it does not give you more time to pay. New York estimated tax payments — including any balance due on your annual return — must still be paid by April 15. Taxpayers who file extensions and assume they can pay later face interest charges from the original due date.

How Jupid Helps with New York Estimated Taxes

Managing estimated tax payments is harder when you're paying at multiple levels — federal, New York State, New York City, and MCTMT. Each has its own calculations, thresholds, and safe harbor rules. Jupid tracks all of these obligations in one place.

When you connect your bank accounts, Jupid automatically categorizes your income and expenses with 95.9% accuracy. The AI calculates your estimated tax liability across all levels — federal self-employment tax, New York State, NYC (if applicable), and MCTMT — based on your actual year-to-date earnings.

Instead of maintaining separate spreadsheets for federal and state estimated payments, you get a unified picture. Jupid flags when your quarterly payments are due and shows you the amount for each level. If your income changes mid-year, the calculations update automatically so you can adjust your remaining quarterly payments and avoid an underpayment penalty.

Jupid works through a web interface and via WhatsApp and iMessage — ask your AI accountant "What are my Q3 estimated payments?" and get a breakdown by jurisdiction based on your real bank transactions.

Connect your bank to Jupid and take the guesswork out of multi-layer estimated tax payments.

Final Thoughts

New York adds real complexity to estimated tax payments. Between state income tax, city income tax, and MCTMT, you may be making estimated payments to three taxing authorities on the same quarterly schedule — on top of federal.

The good news is that all quarterly dates align: April 15, June 15, September 15, and January 15. Batch your payments on the same day each quarter. Know the thresholds ($300 for NY vs. $1,000 federal), apply the right safe harbor, and do not overlook the MCTMT. The penalties are avoidable — but only if you plan ahead.
