New York Taxes on RSUs and Stock Options: A Tech Employee's Guide

New York is home to a significant tech workforce — Google, Meta, Amazon, Bloomberg, and a dense cluster of fintech and startup employees across Manhattan, Brooklyn, and the broader tri-state area. For those employees, equity compensation comes with a tax burden that rivals California: New York City residents face a combined state and city income tax of up to 13.5% on RSU vests and option income, on top of federal taxes.

There's no capital gains preference in New York — the state taxes long-term gains at the same rates as ordinary income, just like California. But New York has its own distinct features that matter for tech workers: no state-level AMT on ISO exercises (an advantage over California), a set of nonresident sourcing rules similar to California's for those who move, and a uniquely aggressive "convenience of the employer" rule that can surprise remote workers at NY-headquartered companies.

This guide covers how New York and New York City tax RSUs, ISOs, NSOs, and ESPP — and what to know before making any decisions about your equity.

New York's tax structure for tech employees

RSUs in New York: ordinary income on two levels

At vest: state and city taxes apply

When RSUs vest, the fair market value at vest is ordinary income — taxed by the IRS, by New York State, and (if you're an NYC resident) by New York City. Your employer withholds federal income tax at the 22% supplemental rate (which underwithholds for most tech employees), plus Social Security and Medicare, plus NY state and city withholding.

The 22% federal supplemental withholding trap applies here just as it does everywhere, but New York has its own supplemental withholding rates that may also underwithhold. Most tech workers in the $300K–$1M total income range will owe more than withheld at tax time. See the RSU after-tax calculator for a specific estimate, and note that it doesn't currently incorporate NY/NYC rates — add ~10.7% (6.85% + 3.876%) to the state/city line if you're an NYC resident below $1.077M in total income.

After vest: no capital gains preference for appreciation

Your cost basis in the shares equals the FMV at vest. Any appreciation after that date is a capital gain when sold — taxed at federal long-term or short-term rates depending on holding period. But for New York purposes, the capital gain is taxed at full ordinary income rates regardless of how long you held the shares. There is no New York long-term capital gains preference.

Practical implication: holding RSU shares after vest saves you nothing at the New York level. The federal benefit of long-term capital gains treatment (paying 15–20% + 3.8% NIIT instead of up to 37%) still applies, but New York takes its full income-rate bite either way. For most RSU holders in HCOL environments, selling promptly after vest remains the cleaner choice unless you have a strong view on the stock.

ISOs in New York: one key advantage over California

No state AMT on ISO exercises

This is the most important structural difference from California. When you exercise Incentive Stock Options, the spread (FMV minus strike price) is an AMT preference item at the federal level — potentially triggering federal AMT (26–28% on the preference amount). California has its own parallel AMT at 7% that applies to the same spread, creating a compounded state-level cost at exercise.

New York State has no equivalent. You may owe significant federal AMT on an ISO exercise, but New York adds no additional state AMT on top. For startup employees or tech workers at companies with meaningful ISO grants, this is a genuine structural advantage of being a New York resident compared to a California resident with the same grant.⁴

At qualifying disposition: ordinary income at NY rates

If you meet the federal holding-period requirements for a qualifying disposition (2 years from grant, 1 year from exercise), the gain is taxed at federal long-term capital gains rates. New York does not honor this preferential treatment — the gain is taxed at full NY ordinary income rates at sale, the same as if it were ordinary income. Combined with the lack of a NY LTCG preference, the "hold for LTCG treatment" calculus for ISOs has the same limitation in New York as in California: the federal benefit is real, but the state portion is unchanged regardless of holding period.

At disqualifying disposition

If you sell before meeting the qualifying disposition thresholds, the spread becomes ordinary income at both the federal and state level — there's no ambiguity. New York taxes the full spread at ordinary income rates on a disqualifying disposition, just as the IRS does.

NSOs in New York

Non-qualified stock options are taxed at exercise: the spread is ordinary income to the IRS, to New York State, and (if you're an NYC resident) to New York City. Withholding occurs at supplemental rates, which may underwithhold given the compound NY + NYC burden.

Post-exercise appreciation held over one year is a federal long-term capital gain (15–20% + NIIT), but New York taxes that appreciation at full ordinary income rates. The exercise timing decision for NSOs is essentially the same as in California: it depends on your current vs. expected future NY rate, your view of the stock, and whether you're planning a move out of New York before a sale.

ESPP in New York

Employee Stock Purchase Plans (§423 plans) in New York follow the same federal structure — but with New York taxing the ordinary-income component at full rates:

• Disqualifying disposition: The 15% discount plus any look-back benefit is ordinary income, taxed at NY + NYC rates on top of federal. Any short-term gain from appreciation is also ordinary income federally and at the NY level.
• Qualifying disposition: The 15% discount component remains ordinary income (full NY rates). Post-purchase appreciation meeting the holding period (1 year from purchase AND 2 years from offering start) is a federal long-term capital gain — but New York taxes it at ordinary income rates. The LTCG benefit is purely federal.

See the ESPP guide and ESPP calculator for after-tax comparison — add your NY + NYC effective rate to the state/city line in the calculator for a more precise picture.

The NYC layer: city tax on top of state

New York City levies its own personal income tax on NYC residents, separate from and in addition to state income tax.² The city tax runs from 3.078% at low incomes to 3.876% at higher incomes — effectively a flat ~3.9% surcharge for most tech workers.

This applies only to residents of the five boroughs (Manhattan, Brooklyn, Queens, The Bronx, Staten Island). If you live in New Jersey and commute to a NYC office, you pay NY state income tax on your NY-sourced work income but do not owe NYC personal income tax. If you live in Hoboken or White Plains and work remotely for a NYC-based tech company — the situation is more complicated, and the "convenience rule" (below) matters a lot.

New York nonresident sourcing rules

Like California, New York has nonresident sourcing rules for equity compensation that follow you after you move.⁵ If you worked in New York during the grant-to-vest period of your RSUs (or grant-to-exercise period for options), New York claims a portion of that income even after you've relocated to a different state.

A concrete example: you're at a Manhattan-based tech company, receive a 4-year RSU grant in January 2024, then move to Florida in January 2026 (2 years in). Your shares continue vesting over the next 2 years. For each vest event after you move, New York will claim approximately 50% of the income (24 NY months ÷ 48 total months during the grant-to-vest period). You'll file a New York nonresident return and owe NY tax on that sourced portion — despite being a Florida resident.

The longer the grant-to-vest period and the more time you spent in New York before moving, the larger New York's claim. As with California, moving before a large vest event (or new grant) is much more effective than moving mid-stream on existing grants.

The "convenience of the employer" rule: the gotcha for remote tech workers

This is New York's most unusual and aggressive tax rule — and one that catches many tech workers off guard.

New York's convenience of the employer doctrine holds that if you work remotely for a New York-based employer, and your remote work arrangement exists for your own convenience (rather than because the employer requires you to work from another location out of business necessity), New York treats those remote work days as New York work days. That means New York income tax applies to all of your salary and equity comp income — even though you're physically located in New Jersey, Connecticut, or any other state.⁶

For tech workers in the NYC metro area who live outside the five boroughs:

• If your employer's primary office is in New York and you could theoretically work from the NY office, your remote workdays are likely treated as NY workdays under the convenience rule. File as a NY nonresident, report your NY-sourced income (which may be all of it), and take a credit in your home state to avoid double taxation (most states credit taxes paid to NY).
• If your employer has no New York office and you work remotely, the convenience rule doesn't apply — you only owe NY tax on actual NY workdays.
• If you're moving out of New York and your employer maintains a NY office, consider whether your remote work situation satisfies the narrow "necessity" exemption before assuming you've escaped NY taxation.

Equity comp during RSU vests: the year-of-move problem

The interaction between the NY sourcing rules and the convenience rule creates complexity in the year you move. If you move from NYC to Florida in July, vesting RSUs throughout the year:

• RSU vests in January–June: you're still a NY resident. Full state + NYC tax on those vests.
• RSU vests in July–December: you're a NY nonresident. But if you're working remotely for a NY-headquartered company, NY's convenience rule may still claim all your wages (including the income equivalent of RSU vests for the days you worked remotely after the move).

The bottom line is that the tax savings from moving away from New York are real — but realized more slowly and partially than most people expect, due to the combination of sourcing rules on existing grants and the convenience rule on ongoing employment. Modeling your specific grant schedule with an advisor before the move prevents unpleasant surprises when you file.

Planning strategies for New York tech employees

1. Maximize retirement account contributions to avoid NY + NYC tax

Traditional 401(k) contributions reduce your NY state and NYC taxable income dollar-for-dollar. At a combined 10.7% (6.85% + 3.876%) for a typical NYC resident in the $300K–$1M income range, the state + city tax savings alone from maxing a 401(k) ($24,500 in 2026) is roughly $2,600. Add the federal marginal benefit and the total deduction value is significant. Mega Backdoor Roth contributions don't reduce current-year NY tax but let you grow assets in a Roth structure — use the Mega Backdoor Roth calculator to see your contribution space.

2. Donate concentrated stock to a DAF — skip NY capital gains entirely

If you donate appreciated stock directly to a donor-advised fund (DAF), you avoid realizing the capital gain entirely. No federal LTCG tax, no NY income tax on the gain. You get a charitable deduction for the full fair market value. For NYC tech employees with appreciated employer stock and any charitable giving intent, this consistently beats selling and donating cash proceeds. See the concentrated stock guide for mechanics.

3. Time ISO exercises around the NY AMT non-issue

Since New York has no state AMT, you can model ISO exercises purely around federal AMT exposure without worrying about a parallel state AMT calculation. The ISO AMT calculator at /iso-amt-calculator/ shows your maximum shares exercisable with zero federal AMT and your exact AMT owed for larger exercises. For New York residents, the state-tax analysis of ISO exercise timing is simpler than for California residents — one fewer AMT to model.

4. Track NY workdays meticulously if you have a hybrid arrangement

For nonresidents who split time between New York and another state, your NY tax liability is proportional to your NY workday percentage. Every documented day working outside New York reduces your NY allocation. Keep calendar records (hotel receipts, Slack timestamps, travel records) to support your allocation if the NY Department of Taxation and Finance audits your nonresident return. This is especially important when you have large RSU vests or option exercises in a given year.

5. If you're planning to move, model the actual grant-by-grant impact

Moving from New York to a lower-tax state (Florida, Texas, Nevada, Washington) looks attractive on paper, but the NY sourcing rules mean you'll continue filing NY nonresident returns and paying NY tax on a diminishing share of existing grants for years after you move. The savings are real and material — but spread over time, not immediate. New grants received after establishing residency elsewhere are the bigger long-term benefit. A fee-only advisor who works with tech employees can model the year-by-year tax trajectory for your specific grant schedule.

What a fee-only advisor can help you model

• Your exact combined federal + NY state + NYC tax rate on each RSU tranche, including the withholding gap and true-up needed
• ISO exercise timing given federal AMT exposure — and why NY's no-state-AMT rule changes the calculation compared to California
• Whether the convenience of the employer rule applies to your remote arrangement, and how to document the "necessity" exception if it might apply
• The year-by-year NY tax trajectory if you're planning a move — which grants benefit most from moving, and when the real savings kick in
• DAF and charitable giving strategies for appreciated equity, including how to time contributions around vest schedules
