How Each State Taxes Capital Gains

Most states do not have a preferential long-term capital gains rate at all. They take your gain, drop it into ordinary income, and tax it at whatever bracket that lands you in. Hold an asset thirty years or thirty-one days and many states treat the result identically.

That single fact is why two people with the same sale, the same gain and the same federal bill can be $60,000 apart.

The three ways states handle it

1. Tax it as ordinary income. The large majority. Your gain is income, and it is taxed at the state's regular rates. This is the default assumption you should make unless you know otherwise.

2. Don't tax income at all. Nine states have no broad personal income tax: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas, Washington and Wyoming. A capital gain generates no state income tax in these states — with one important asterisk below.

3. Offer a partial exclusion, deduction or credit. A minority of states let you exclude a percentage of long-term gains or claim an offsetting credit. This is where the real money hides, and it is also where the rules change most often.

Top state rates on a capital gain

These are top marginal rates applied to gains taxed as ordinary income. Your actual rate depends on total income.

The genuinely odd ones

Washington is the asterisk on the no-income-tax list. Since 2022 it has levied a 7% excise tax on long-term capital gains above roughly $250,000 per year. Real estate is excluded. Because it applies per year and above a threshold, spreading a sale across years can drop you under it entirely — one of the cleanest planning outcomes anywhere in the country.

Massachusetts taxes long-term gains at 5%, which looks mild until the 4% surtax on income above roughly $1 million engages. A single large sale usually triggers it, taking the effective rate to 9% on the portion above the threshold. Spreading the sale is unusually effective here for the same reason it is in Washington: the surtax is measured one year at a time.

California has no preferential rate and adds a 1% Mental Health Services surcharge on income over $1 million, producing the highest combined burden in the country.

New Jersey is a trap for people carrying losses. New Jersey does not allow capital losses to offset ordinary income, and its treatment of loss carryforwards is far less generous than the federal rules. A federal plan built around netting losses can fall apart at the New Jersey line.

New York City stacks a local income tax of roughly 3.876% on top of the state's 10.9%. A city resident selling a large asset faces a combined state and local rate near 14.8%.

Several states offer partial exclusions or credits on long-term gains — Wisconsin, New Mexico, South Carolina, Arkansas, North Dakota, Montana and Iowa have all had some form of exclusion, deduction or credit. These are the most valuable and the most volatile rules in state capital gains taxation: the percentages get amended, phased and repealed regularly, and several have asset-type conditions attached such as farm property or in-state businesses. Confirm the current-year rule with a preparer in that state before relying on one. We deliberately do not publish a percentage table for these, because a stale number here is worse than none.

Which state even gets to tax you?

Two rules cover most situations:

• Real property is taxed where it sits. Sell an apartment building in California and California taxes the gain, no matter where you live. Many states require withholding at closing from non-resident sellers.
• Everything else generally follows your residency on the date of sale — stocks, collectibles, business interests.

That second rule is what makes people consider moving before a large sale. It can work, and states with the most to lose scrutinise it hardest. California in particular examines the totality of your circumstances rather than a day count alone: where your family lives, where you are registered to vote, where your professional licences sit, where you actually spend your time. A move made only on paper and only around a sale is exactly the fact pattern auditors look for.

Why the state layer changes the deferral math

The federal argument for spreading a sale is about brackets and the 3.8% surtax. The state argument is often stronger, because these thresholds are calculated one year at a time:

• Washington's $250,000 excise threshold
• Massachusetts' $1 million surtax threshold
• California's $1 million Mental Health Services surcharge

Spread a gain across enough years and you can fall below a threshold entirely rather than merely reducing the rate applied above it. In Washington that can mean the state tax disappears rather than shrinks.

Frequently asked

Q: Which states have no capital gains tax? A: Alaska, Florida, Nevada, New Hampshire, South Dakota, Tennessee, Texas and Wyoming have no broad personal income tax, so a capital gain produces no state income tax. Washington has no general income tax but does impose a 7% excise tax on long-term gains above roughly $250,000 per year, with real estate excluded.

Q: Do states have a lower long-term capital gains rate like the federal 15% or 20%? A: Most do not. The majority tax capital gains as ordinary income with no holding-period preference. A minority offer a partial exclusion, deduction or credit instead, and those rules change frequently.

Q: If I move to Florida before selling, do I avoid my old state's tax? A: Sometimes, and it depends heavily on the asset and the facts. Real property is taxed by the state where it is located regardless of residency. For other assets, residency on the sale date generally governs, but high-tax states audit residency changes around large sales closely and look at far more than how many days you spent where.

Q: Does my state tax collectibles at 28% like the federal rules? A: No. The 28% collectibles ceiling is a federal concept. States that tax capital gains generally apply their ordinary rates to a collectible gain, with no special category.
