New Jersey Capital Gains Tax in 2026

New Jersey Taxes a Gain Like a Paycheck, Because That Is What It Does

The Division’s own capital gains page is four paragraphs long and it settles the question in the first two sentences:

and then, on whether the length of your hold matters:

That is the whole design. There is no gains schedule, no preferential column in the tax table, and no worksheet that behaves like the federal Qualified Dividends and Capital Gain Tax Worksheet. Your gain joins the rest of your income and the schedule is run once over the total, which the instructions say plainly:

Two consequences follow, and they pull in opposite directions. The bad one: a nurse in a high bracket pays more on a gain than the federal system charges, because 10.75 percent is above the federal 20 percent plus 3.8 percent only for people whose income sits in the top band, and it is above the 15 percent federal rate for almost everyone else. The good one, which almost no guide mentions: some gains are not taxed at all in New Jersey, including the Treasury bill interest and bond gains the federal return counts. Both of those are worked through below.

The Schedule Your Gain Runs Through

These are the two schedules printed in the NJ-1040 instructions. Use the left pair of columns if you file single or married filing separately, and the right pair if you file jointly, as head of household, or as a qualifying widow or widower.

Three things worth knowing about how this table is used. First, it is marginal: only the dollars inside a band pay that band’s rate, so a nurse at $1,000,000 is not paying 10.75 percent on the first dollar. Second, below $100,000 of taxable income the instructions let you use the tax table instead of the schedules, and the table’s dollar amounts differ from the schedule arithmetic by a few dollars; at $100,000 and above the schedules are required. Third, and this is the part that decides your bill, the gain is added before the schedule is run, which is why the same gain costs two people different money:

Read the third column, not the second. A $100,000 gain costs $4,244 in an otherwise empty year and $8,970 in a $600,000 year, and nothing about the investment changed. The rate on the last dollar is the number to watch, because it is the rate every extra dollar of gain pays while you stay in that band.

Where New Jersey Copies the Federal Rules Word for Word

The residence exclusion is the one place the state hands you a big number, and it does it by adopting the federal test rather than inventing its own:

Then the amounts:

Three practical points sit inside those four sentences. The exclusion is not limited by age in New Jersey any more than it is federally; the old state rule that gave people over 65 a one-time $100,000 exclusion is gone, and the page says so in the phrase “regardless of age.” The ceiling follows your filing status, so married filing separately gets $250,000 each and not $500,000 between you. And because New Jersey reads the federal form, the federal two-year waiting period comes along with it: exclude a sale on your New Jersey return, and a second sale inside two years does not get a second exclusion.

Four Places the Two Returns Disagree

This is where a New Jersey sale stops being a footnote on the federal return.

1. The basis. The instructions give the general rule and then take it back:

Depreciation is the usual culprit. A house you rented for three years, or an interest in a partnership that held property, can carry a smaller New Jersey basis than federal basis, and a smaller basis is a bigger gain. The adjustment comes off Form GIT-DEP, and it is the one line on the return where copying your federal Schedule D figure produces the wrong New Jersey answer.

2. Exempt obligations. New Jersey does not tax the gain on federal debt:

Treasury bills and notes, series EE and I savings bonds, and the capital gain distributions from a fund that holds them: the federal return taxes these and the New Jersey return does not. For a nurse whose brokerage account is mostly T-bills and Treasury ETFs, this is the one place where the state answer is genuinely lower, and it is applied on the state return rather than by any election.

3. Losses. Federal rules let a $3,000 net loss offset ordinary income and carry the rest forward forever. New Jersey does neither:

Losses can fight gains inside the same category in the same year, which the instructions put this way:

After that, whatever is left over is gone. A stock loss cannot touch your wages, cannot touch a gain on a house, and cannot be used next year. The federal return keeps it; the state return forgets it.

4. Timing. The instructions require the same year on both returns: Income must be recognized and reported in the same period as it is recognized and reported for federal purposes. An installment sale is reported in the year the federal return reports it. There is no New Jersey version of spreading it differently.

What the Gain Actually Costs: Run the Year Twice

Here is the arithmetic behind the calculator, on a real case. A single nurse sells her New Jersey main home for $700,000 with $42,000 of selling costs against a $250,000 basis. The gain is $408,000, the exclusion covers $250,000, and $158,000 is left.

If that sale is the only income in the year, the schedule is run on $158,000, which produces $7,938: $280 on the first $20,000, $263 on the next $15,000, $175 on the next $5,000, $1,934 on the next $35,000, and 6.37 percent of the remaining $83,000. That is an effective 5.0 percent on the gain.

Now put $120,000 of travel nursing wages in the same year, which is what a nurse who kept working has. The year’s total is $278,000, the schedule produces $15,582, and the wages alone would have produced $5,518. The gain now costs $10,064, which is 6.4 percent of it, all because the exclusion is applied after the stacking rather than before it. Same house, same closing, $2,126 of difference.

If You No Longer Live in New Jersey: the 2 Percent at Closing

This is the rule that catches travel nurses hardest, because the whole point of the job is that you move. A nonresident is still taxed on New Jersey-source income, and the nonresident instructions name real property first:

So moving to Texas does not take a New Jersey house out of New Jersey’s reach. It also puts a form in front of your closing. Under the GIT/REP rules the settlement agent cannot record the deed without one, and if you are a nonresident seller the form carries a payment:

The formula is the highest tax rate times your share of the federal gain, with 2 percent of your share of the price as a floor. Worked on case H below, a $540,000 rental with $388,000 of federal gain produces a prepayment of $41,710 at closing, while the New Jersey tax on the whole sale turns out to be $22,972. The difference is not a penalty and not extra tax: it is your money held by the state until you file a nonresident return and claim it back. File that return, attach the GIT/REP-2 receipt, and the overpayment comes out as a refund.

Two details people lose money on. A loss does not excuse the payment, because the floor is written against the price rather than the gain. And the Realty Transfer Fee exemptions do not carry over: the state’s own FAQ says the transfer-tax relief does not touch the 2 percent.

If Another State Taxed the Same Gain

A nurse who owns a house in New York, Pennsylvania, or North Carolina while living in New Jersey faces two states on one sale. New Jersey’s answer is a credit rather than an exclusion:

and its limit:

The credit is computed on Schedule NJ-COJ, one schedule per jurisdiction per tax, and the ceiling matters more than the arithmetic: if the other state’s rate on that income is lower than New Jersey’s, you pay New Jersey the difference rather than getting the whole other-state tax back. Because New Jersey’s rates reach 10.75 percent, that difference is real for a large gain.

The one trap on this page for a nurse working in Philadelphia: the reciprocal agreement between the two states covers wages, and nothing else.

So a gain on a Pennsylvania house is taxed by Pennsylvania with no reciprocal relief, and the credit route is the Schedule NJ-COJ one, while the city wage taxes you paid in Philadelphia can also be credited. Different forms, different lines, same principle: New Jersey taxes the whole income and gives back only what another jurisdiction genuinely charged on it.

Age 62 or Older: an Exclusion You May Not Have Used Up

New Jersey’s retirement exclusions are worth more than the federal ones for a retired nurse with a small gain, because the state lets an unused pension exclusion be spent on other income:

The catch is a work test rather than an income test. Worksheet D asks for your wages, net business profits, partnership share and S corporation share, and if those add up to more than $3,000 the unclaimed exclusion is gone:

That $3,000 line is the reason this works for a retired nurse who took no contracts and does not work for one who did. The maximum exclusion the chart gives a 62-or-older filer is $100,000 on a joint return, $75,000 single, head of household or qualifying widow, and $50,000 married filing separately, and it phases down as total income moves through $100,000 to $150,000. Part-year residents use Worksheet E instead of Worksheet D.

Twelve Situations, Worked By Hand

Every row below was produced by the same engine the panel uses, from the rules quoted on this page, so you can compare your own answer against a case that looks like yours.

Case C and case B are the same sale in two different years, and they are the point of this page. Case H is the one a nurse who has already left New Jersey will recognize: the prepayment column is what leaves the closing table, and the tax column is what the state actually keeps.

Frequently Asked Questions

Does New Jersey tax long-term capital gains at a lower rate?

No. New Jersey does not differentiate between short-term and long-term capital gains. Every rate on this page applies to a gain held one month or one decade, and the only thing that changes the bill is what else was in the year.

Do I owe New Jersey tax if I sold my home and did not live there at closing?

If the property is in New Jersey, yes. All other types of income from New Jersey, such as gain from sale of property located in New Jersey, are taxable. You also face the GIT/REP prepayment at closing, which is collected whether or not you made money on the sale.

Is the federal $250,000 exclusion good on a New Jersey return?

Yes, and it is the same test rather than a parallel one: This is true regardless of age, as long as you owned and lived in the residence for 2 of the 5 years prior to the sale. Married filing jointly reaches $500,000; every other status is capped at $250,000.

Can I deduct a capital loss against my nursing wages in New Jersey?

No. You cannot apply a net loss in one category of income against income or gains in a different category on your NJ-1040. And there is nothing to bank: No carryback or carryover of losses is allowed when reporting income on your NJ-1040. The federal return keeps the carryover, and the two returns then report the same year very differently.

Are Treasury bill gains taxed in New Jersey?

No. Gains or losses realized from the sale or exchange of exempt obligations such as United States Treasury bonds are not taxable, nor are capital gains distributions from a qualified investment fund attributable to exempt obligations. This is one of the few places where the state’s answer is smaller than the federal one, and it needs no election to claim.

Does the 2 percent at closing count as the tax on my gain?

It is a prepayment, not the bill. The real number is computed on the NJ-1040NR, and the prepayment is credited there. On case H above the closing paid $41,710 against a tax of $22,972, and the $18,738 difference is recovered by filing.

Next step: Run your own sale through the panel twice: once with the wages you actually earned and once without them. If the two answers differ by more than you expected, the difference is the stacking, and that is the number to take to a preparer.
