New York Capital Gains Tax Calculator

New York taxes capital gain as ordinary income and stacks it on top of the other taxable income you enter, then walks the result through a nine-band schedule running from 4% to 10.9%.

At the defaults, $100,000 of gain over $75,000 of other income, the New York tax is $5,971.75, an effective rate of 5.97% on the gain and a marginal rate of 6.00%, leaving $94,028.25 retained. The two rates differ slightly because the stack begins at $75,000, just below the $80,650 edge, so the first $5,650 of gain is taxed at 5.5% before the 6% band takes over.

The twelve-row sweep prices a $16,666.67 tier at $971.75 in row 1 and $200,000 at $12,478.35 in row 12. Those are not in a twelve-to-one ratio, and the reason is that the larger tier reaches the 6.85% band while the smaller one does not.

New York taxes a capital gain as ordinary income on a nine-band schedule from 4% to 10.9%, with the highest bands reserved for income above $5 million and $25 million. This page covers the state layer only; a New York City resident owes city income tax on the same gain on top of what is shown here.

The gain is stacked on top of your other income and walked through the bands from there.

Step by step, with your numbers:

1. Start with the net gain. Capital losses and loss carryforwards are netted against the gain before anything else happens.
2. Stack the gain on your other income. Ordinary income fills the lower brackets first and the gain sits on top of it, so the gain is taxed at whatever rates are still open above your salary. The same gain costs a high earner more than it costs a low earner. Enter other income as a taxable-income figure: the calculator does not subtract a standard deduction or personal exemption for you.
3. Walk the brackets. The slice of the gain that falls in each band is multiplied by that band's rate, and the pieces are added together.
4. Effective rate. Total New York tax divided by the whole realized gain. On a graduated schedule this sits below the top marginal rate, because the lower slices were taxed at lower rates.
5. Net proceeds. Subtract the state tax from the gain to get what you keep before federal tax.

Consider an investor in New York who realizes $100,000 in capital gains on top of $75,000 in baseline ordinary income for the year.

1. Stack the income. New York taxes capital gains as ordinary income. Since income fills the lower brackets first, the $75,000 of baseline income already occupies the lower tiers, so the $100,000 gain stacks on top and pushes into higher brackets.
2. Apply the marginal brackets. Working through New York's bracket schedule, each slice of the gain is taxed at its own bracket's rate, with the highest slice reaching the 6.00% top marginal bracket.
3. Total state tax due. Summing the tax owed across every bracket the gain touches produces a total New York state tax liability of $5,971.75.
4. Effective rate. Dividing that liability by the $100,000 gain gives an effective rate of 5.97%, lower than the 6.00% marginal bracket since only the top slice of the gain is taxed at that rate.
5. Net proceeds. After paying $5,971.75 in state tax, the investor keeps $94,028.25 of the $100,000 gain, before any federal tax applies.

Each additional $1,000 of gain costs $60.00 at the defaults, moving the tax from $5,971.75 at $100,000 of gain to $6,031.75 at $101,000.

The first edge, at $80,650 of total income. With $75,000 of other income it arrives after just $5,650 of gain. At $5,600 of gain the tax is $308.00 and the marginal rate reads 5.50%. At $5,700 it is $313.75 and the marginal rate reads 6.00%. Those $100 of gain cost $5.75 against $5.50 below the line, so the edge is worth $0.25. A filer with modest other income crosses this edge almost immediately.

The second edge, at $215,400 of total income. That arrives at $140,400 of gain. At $140,300 the tax is $8,389.75 with a 6.00% marginal rate; at $140,500 it is $8,402.60 with a 6.85% marginal rate. Those $200 of gain cost $12.85 against $12.00 inside the lower band, making the edge worth $0.85. The effective rate output reads 5.98% on both sides and gives no sign that anything happened.

The other-income field is worth $540.00 here. Set other taxable income to $0 and the same $100,000 gain is taxed at $5,431.75 rather than $5,971.75, an effective 5.43%, because the gain then fills the 4%, 4.5% and 5.25% bands on its way up.

Filing status is worth $404.50 at the defaults. Married filing jointly returns $5,567.25 against the single filer's $5,971.75, an effective 5.57%. The joint schedule's 5.5% band runs to $161,550 rather than $80,650, which is where the saving comes from.

The reverse question: how much gain can be realised before reaching the 6.85% band? With $75,000 of other income, $140,300 of gain keeps the marginal rate at 6.00% and costs $8,389.75. Crossing costs $0.85 on the next $200, so the answer matters far less than the question implies.

The New York City layer this page never shows. The figures here are state tax only. A New York City resident owes a separate city income tax on the same gain, and the engine's own note on the New York bracket table records that neither the city tax, the Yonkers surcharge, nor the supplemental benefit recapture that applies above $107,650 of New York AGI is modelled. At the defaults the stack reaches $175,000, well past that recapture threshold, so the $5,971.75 shown is a floor rather than a full answer for a city filer.

While this calculator provides penny-exact state statutory modeling, additional federal and transactional complexities warrant supplementary review: - Federal Capital Gains Taxes: Federal long-term brackets (0%, 15%, 20%) and short-term ordinary rates up to 37% under IRC § 1. - Net Investment Income Tax (NIIT): The 3.8% surtax on net investment income under IRC § 1411 for single filers over $200,000 (married joint over $250,000). - Alternative Minimum Tax (AMT): Federal AMT calculations under IRC § 55 impacting incentive stock option (ISO) exercise spread. - Section 1031 Like-Kind Exchanges: Tax deferral mechanisms for real property held for productive use in trade, business, or investment. - Qualified Small Business Stock (QSBS): Federal Section 1202 gain exclusions where state conformity varies significantly.

• Assuming Federal Rate Parity: Most states do not offer preferential long-term capital gains rates; gains are taxed at standard ordinary income rates.
• Failing to Track Holding Periods: Short-term gains (assets held ≤1 year) generate higher federal tax liabilities even if state rates treat both holding periods identically.
• Underestimating Multi-State Apportionment: Selling real estate or business assets located in other jurisdictions triggers multi-state non-resident return filing obligations.
• Neglecting Underpayment Penalties: Substantial one-time liquidity events require prompt estimated tax payments within the quarter of sale to avoid statutory penalties.
• Mismatched Cost Basis Records: Failure to document reinvested dividends, stock splits, or structural return-of-capital distributions leads to inflated taxable gain calculations.
