New York “Convenience of the Employer” Rule (2026): Why NJ, CT & PA Remote Workers Still Owe NYS Income Tax & How to Pass a Bona Fide Office Audit
Understand New York’s Convenience of the Employer rule (20 NYCRR 132.18 & TSB-M-06(5)I) for NJ, CT, and PA remote workers, NJ/CT retaliatory credits, and bona fide office rules.
By Pablo Cirre Gómez and East Corp Capital Quantitative Desk
If you live in New Jersey, Connecticut, Pennsylvania, or Florida and work from your suburban home office three, four, or even five days a week for a Manhattan-headquartered company, a jarring surprise awaits on your W-2 Box 16: New York State treats 100% of your remote work-from-home days as if you physically sat at a desk in Midtown Manhattan. Under New York’s aggressive “Convenience of the Employer” regulation (20 NYCRR § 132.18(a))—upheld by the New York Court of Appeals in Zelinsky v. Tax Appeals Tribunal—days worked outside New York by a non-resident assigned to a New York office may be excluded from New York tax only if worked out of strict employer necessity, not employee convenience.

How the Form IT-203-B Workday Allocation Fraction Works Under Audit
When a non-resident files New York Form IT-203 and Schedule IT-203-B, New York taxes your total compensation multiplied by a fraction: New York Workdays ÷ Total Workdays Worked Everywhere (typically ~235–240 days after subtracting weekends, holidays, and PTO). Under the Convenience of the Employer rule, if your HR system assigns you to a New York City office and you work 90 days in Manhattan and 150 days from your kitchen or study in Ridgewood NJ, Westport CT, or Bucks County PA, New York auditors reclassify all 150 home days as “days worked outside NY for the employee’s convenience”—pushing your NY numerator from 90/240 (37.5%) to 240/240 (100%).

The Two Legal Ways to Defeat the Convenience Rule: Out-of-State Branch Assignment vs. TSB-M-06(5)I Bona Fide Home Office
There are exactly two legally bulletproof methods to stop New York from taxing your remote days:
- Formal HR Reassignment to a Non-NY Employer Office: If your company operates a real office in Jersey City, Short Hills, Stamford, Greenwich, Philadelphia, or Miami and formally reassigns your primary reporting location to that non-NY office in writing, the Convenience of the Employer rule no longer applies to your home days! You owe NY tax only on the exact days you physically travel into New York for meetings.
- The TSB-M-06(5)I “Bona Fide Employer Office” Test: Under NYS Technical Memorandum TSB-M-06(5)I, a home office qualifies as a bona fide employer office only if it either (a) contains specialized scientific/testing facilities unavailable in NY, OR (b) satisfies at least 4 of 6 Secondary Factors (employer requirement in employment contract, employer reimburses >80% of office expenses, employer withholds home-state tax, employer listed on home signage/directories) AND at least 3 of 3 Other Factors (separate telephone line, dedicated entrance/workspace, business clients regularly meet you at the home office).
Frequently Asked Questions & Statutory Rules (2026)
What is New Jersey’s 50% tax credit for challenging a New York Convenience of the Employer audit?
Under New Jersey P.L. 2023, c. 125, if a New Jersey resident appeals a New York Convenience of the Employer tax assessment and wins a refund from New York (which then increases their NJ tax due via Schedule NJ-COJ adjustment), New Jersey grants the taxpayer a special credit equal to 50% of the additional NJ tax owed!
If I live in Pennsylvania or Florida (low/zero tax states) and work remotely for a NYC company, how much does the Convenience Rule cost me?
Unlike NJ and CT residents (who get a partial resident credit for NY taxes), a Pennsylvania resident (3.07% state tax) or Florida resident (0% state tax) loses the entire difference between NY’s 6.0%–10.9% non-resident rate and their home state rate unless their primary office of record is reassigned outside New York.
Does working at a client site in Boston, Chicago, or London count as a non-NY workday?
Yes! Business travel days where you physically perform services at a client’s premises, conference, or third-party facility outside New York State are performed out of "employer necessity" and are excluded from the NY numerator on Form IT-203-B.
Did Connecticut and New Jersey pass their own retaliatory Convenience of the Employer rules?
Yes. Both Connecticut (C.G.S. § 12-711(b)(2)(C)) and New Jersey (N.J.S.A. 54A:5-8) now apply a reciprocal Convenience of the Employer rule exclusively to non-residents who live in states that impose a convenience rule (such as New York residents working remotely from Westchester or NYC for a Stamford CT or Jersey City NJ employer).
