New York’s income tax nexus rules reach further than most people expect: an individual becomes taxable on worldwide income by keeping an apartment in the state and spending more than 183 days there, and a business becomes taxable by selling more than $1 million to New York customers with no office, employee, or property in the state. Remote workers for New York employers get caught by a separate rule that treats work-from-home days in another state as if performed in Manhattan. Ignore the resulting filing obligation and penalties can stack to roughly a quarter of the tax owed, plus interest, for every open year the state uncovers.
When New York Taxes an Individual
There are two ways an individual becomes a New York resident for income tax purposes, and residence means tax on your entire worldwide income, not just what you earn inside the state.
The first is domicile. If New York is your true, fixed, permanent home, you are a resident by default. Escaping domicile requires proving you abandoned it and either spent 30 or fewer days in New York that year or maintained no permanent place of abode there at all.1New York State Senate. New York Tax Law 605 (2025) – General Provisions and Definitions
The second is statutory residence, and this is the trap. If you are domiciled somewhere else but you maintain a permanent place of abode in New York and spend more than 183 days of the year in the state, New York treats you as a resident.2New York State Senate. New York Tax Law Section 605 – General Provisions and Definitions “Permanent place of abode” is broader than ownership. The Tax Department counts any dwelling you maintain and have access to throughout substantially all of the year: a rented apartment, a corporate-leased unit kept available for your visits, even a room in a relative’s home that you can use at will.3New York State Department of Taxation and Finance. Permanent Place of Abode
If you split time between New York and another state, count days carefully. The Tax Department audits these situations aggressively. Breaking statutory residence means either giving up the dwelling or staying out of the state for at least 183 days each year.
The Convenience of the Employer Rule
The rule that catches the most remote workers off guard is New York’s convenience of the employer test. A nonresident who works from home in another state for a New York employer must allocate those work-from-home days to New York unless the remote work was performed out of necessity for the employer, not the employee’s personal convenience.4Legal Information Institute. N.Y. Comp. Codes R. and Regs. Tit. 20 132.18 A New Jersey resident who telecommutes four days a week for a Manhattan employer owes New York income tax on those four days of wages as if the work had happened in New York.
The only escape is showing that your home office qualifies as a bona fide employer office. The Tax Department’s guidance uses a tiered test that starts with whether your home office contains or is near specialized facilities that can’t be replicated at the employer’s New York location. If that primary factor isn’t met, the analysis moves to a scoring exercise across secondary and additional factors covering things like whether remote work is a condition of employment, whether clients are regularly met at your home, whether the employer reimburses at least 80% of home office expenses, and whether the address appears on business cards.5New York State Department of Taxation and Finance. TSB-M-06(5)I – New York Tax Treatment of Nonresidents and Part-Year Residents Most remote workers who simply prefer working from home cannot come close to satisfying it.
New York’s personal income tax rates run from 4% at the bottom to 10.9% on taxable income above $25 million, with the 9.65% bracket starting at much lower income levels. A remote worker caught by the convenience rule can face a substantial and unexpected bill, especially if the employer never withheld New York tax.
Double Taxation for Remote Workers
The obvious problem is that a nonresident telecommuter can owe tax on the same wages to both New York and their home state. New York residents who pay tax to another state receive a nonrefundable credit against New York tax, capped at the New York tax attributable to the double-taxed income.6New York State Senate. New York Tax Law Section 620 – Credit for Income Tax of Another State Nonresidents look the other direction, to their home state.
Most states offer a resident credit for taxes paid elsewhere, but several push back specifically on New York’s convenience rule. New Jersey, Connecticut, and Pennsylvania have all declined at times to credit taxes owed under the convenience doctrine. Affected workers can end up paying an effective double tax on part of their income, with no clean fix short of restructuring the work arrangement.7New York State Department of Taxation and Finance.

When New York Taxes a Business
p>Corporate franchise tax nexus comes through two doors: physical presence or receipts.
Physical Presence
A foreign corporation owes franchise tax if it does business in New York, employs capital there, owns or leases property there, or maintains an office there.9New York Codes, Rules and Regulations. 20 CRR-NY 1-3.2 – Foreign Corporations Subject to Tax “Doing business” is read broadly, covering all activities that occupy the time or labor of people for profit, whether or not the business actually profits in New York.10Legal Information Institute. N.Y. Comp. Codes R. and Regs. Tit. 20 1-2.4 – Foreign Corporation – Doing Business A single employee performing services in the state can be enough.
There is a narrow trade show safe harbor. A foreign corporation does not establish nexus solely by attending trade shows in New York for 14 or fewer days in the taxable year, provided the primary purpose is displaying goods or promoting services, no completed sales occur at the show, and any orders are sent out of state for acceptance. Cross 14 days, close a sale on the floor, or perform any non-solicitation activity at the event, and the protection disappears.
Economic Nexus: The $1 Million Receipts Threshold
Physical presence isn’t required. A corporation that derives $1 million or more in receipts from activity in New York during the taxable year owes franchise tax on that basis alone.11New York State Senate. New York Tax Law Section 209 – Imposition of Tax; Exemptions The base threshold is subject to inflation adjustment when cumulative CPI change exceeds 10% since January 1, 2015, or since the last adjustment, rounded to the nearest thousand dollars, so the operative number in a given year may be higher than $1 million. Check the Tax Department’s current guidance if you’re near the line.
“Receipts” tracks the apportionment rules under Section 210-A, which generally look at the destination of goods sold or the location where the customer receives the benefit of a service. A software company headquartered in Texas with $1.2 million in annual subscriptions from New York users has nexus even if no employee has ever set foot in the state. Service and software companies with national customer bases cross the threshold routinely without realizing it.
Federal Protection Under Public Law 86-272, and Its Limits
Public Law 86-272 blocks any state from imposing a net income tax on a company whose only in-state activity is soliciting orders for tangible personal property, provided orders are sent outside the state for approval and fulfilled from outside the state.12Office of the Law Revision Counsel. 15 U.S.C. 381 – Imposition of Net Income Tax A traveling salesperson who visits New York with samples, takes orders, and ships from an Ohio warehouse sits inside the protection.
The shield is narrow. Repairs, post-sale technical support, training, and installation in New York all break it. Services, digital products, and licenses are not covered at all because they are not tangible personal property.
New York’s regulations also identify internet-based activities that go beyond mere solicitation and strip the protection:
- Providing post-sale customer support to New York buyers via email or website chat.
- Accepting electronic applications from New York visitors for non-sales positions.
- Placing cookies on New York customers’ devices to gather browsing data used for production, inventory, or product development decisions.
- Transmitting code or electronic instructions to fix or upgrade products already sold to New York customers.
The reasoning is that a company would engage in these activities regardless of whether it was soliciting sales, so they aren’t ancillary to solicitation.13Legal Information Institute. N.Y. Comp. Codes R. and Regs. Tit. 20 1-2.10 – Foreign Corporations Many e-commerce businesses that assumed P.L. 86-272 covered them are exposed under these rules.
Even when the protection applies, it only blocks taxes measured by net income. Corporations with New York nexus owe at least a fixed dollar minimum tax regardless of profit, ranging for most C corporations from $25 when New York receipts are $100,000 or less up to $200,000 when receipts exceed $1 billion.14New York State Senate. New York Tax Law Section 210 – Tax Sales tax collection obligations also survive P.L. 86-272 entirely.
Penalties If You Should Have Filed and Didn’t
The cost of ignoring a New York filing obligation compounds fast. For personal income tax, late filing runs 5% of the tax due per month or partial month up to 25%, and late payment adds 0.5% per month, also capped at 25%. A negligence finding tacks on 5% of the underpayment plus 50% of the interest owed on it. Fraud doubles the entire underpayment.15New York State Department of Taxation and Finance. Interest and Penalties For corporations, the combined failure-to-file and failure-to-pay penalty can reach 30% of the tax due.16New York Codes, Rules and Regulations. 20 CRR-NY 536.1 – Penalties and Interest
Penalties stack and accrue interest. When the Tax Department turns up unfiled years during an audit, it assesses penalties for every open year at once, which is how a manageable liability becomes a six-figure problem.
Voluntary Disclosure Before the State Finds You
If you’ve realized you should have been filing and haven’t been, coming forward first changes the math. The Tax Department’s voluntary disclosure and compliance program waives penalties in full and forgoes criminal referral for the failure to file, provided you qualify.17New York State Department of Taxation and Finance. Voluntary Disclosure and Compliance Program
Eligibility has four conditions: you are not currently under audit for the taxes you want to disclose, you have not already received a bill for them, you are not under criminal investigation by any New York State agency, and you are not disclosing participation in a listed tax shelter.17New York State Department of Taxation and Finance. Voluntary Disclosure and Compliance Program The program can also limit how far back you have to file through a look-back provision, though the number of years depends on your circumstances.
You still owe the full tax and interest for the covered years. Eliminating penalties that would otherwise reach 25% to 30% of the liability is the point. Once the Tax Department contacts you, the door closes.
