The Step-Up in Basis: Why Most Heirs in North Jersey Pay Zero Capital Gains Tax When Selling an Inherited Home

The single most important tax break for anyone who inherits a home in New Jersey is something most heirs have never heard of. It is called the step-up in basis, and it is the reason that families selling inherited property in Clifton, Paterson, Passaic, Totowa, Woodland Park, Haledon, and Garfield almost always pay zero federal capital gains tax. Here is how it works. When you inherit a home, the IRS does not measure your gain from what the original owner paid for it. It measures your gain from what the home was worth on the date of their death. That is the step-up. If your parents bought their home for $80,000 in 1985 and it was worth $480,000 when they passed away, your cost basis is $480,000, not $80,000. If you sell it six months later for $485,000, your taxable gain is $5,000. Not $405,000. That $400,000 of appreciation during their lifetime is wiped out from a capital gains perspective. It is the closest thing to a free lunch in the tax code, and it applies to almost every inherited home sale in North Jersey. Here is exactly how the rule works, what the numbers look like on real properties in this market, the few situations where it does not apply, and how to make sure you get the full benefit.

What the Step-Up Actually Does to Your Cost Basis

Under IRC Section 1014, when you inherit property, your tax basis is the fair market value of the property on the date of the decedent's death. Not the date they bought it. Not the date they refinanced. Not the date they added a deck. The date of death value. Period. The executor can also elect to use an alternate valuation date six months after the date of death if the estate tax return requires it, but for most estates the date of death value is what controls. The step-up applies to every asset that passes through the estate. Real estate. Stocks. Mutual funds. Business interests. Even artwork. For the vast majority of inherited homes in Passaic and Bergen County, the date of death value is close to what the home would sell for on the open market. If the executor obtains a professional appraisal or uses a broker's opinion of value to establish the date of death value, that appraisal becomes the basis for calculating your gain when you sell. If the appraisal says the home was worth $450,000 on the date of death and you sell it six months later for $460,000, your taxable gain is $10,000. If you sell it for $440,000, you actually have a capital loss of $10,000, which you can use to offset other capital gains on your tax return.

Real Numbers: What This Looks Like on a Home in Clifton

Let me show you the difference the step-up makes. A couple in Clifton bought their home in 1992 for $180,000. They raised their family there, maintained it well, and the neighborhood appreciated significantly. The husband passed away in 2024, and the wife passed away in 2026. The adult children inherit the home. On the date of the surviving parent's death, a professional appraisal values the home at $620,000. The children sell the home four months later for $635,000. Without the step-up, their gain would be measured from the original $180,000 purchase price. That is a gain of $455,000. At the 15% federal long-term capital gains rate plus New Jersey's ordinary income rate of roughly 5.5% for middle-income filers, the combined tax would be around $93,000. That is a massive hit. With the step-up, their basis is $620,000, the date of death value. Their gain is $635,000 minus $620,000, or $15,000. Their federal capital gains tax at 15% is $2,250. Their New Jersey tax on that gain at roughly 5.5% is $825. Total tax bill is $3,075 instead of $93,000. That is the step-up at work. The $440,000 of appreciation that happened during the parents' lifetime is simply gone from the tax calculation.

I have run this exact scenario on dozens of inherited homes in Paterson, Clifton, Passaic, Totowa, Woodland Park, Haledon, and Garfield. In every case, the heirs were expecting a big tax bill because they assumed their gain was the difference between the sale price and what their parents paid decades ago. And in every case, the step-up reduced their tax liability to nearly zero. The relief is real.

Does New Jersey Tax Capital Gains on Inherited Property Differently?

New Jersey conforms to the federal step-up in basis rule. The same $620,000 basis applies for New Jersey state tax purposes as it does for federal. However, New Jersey does not offer a preferential long-term capital gains rate. Capital gains in New Jersey are taxed as ordinary income at your marginal rate, which ranges from 1.4% to 10.75% depending on your income. The federal rate for long-term capital gains is 0%, 15%, or 20% depending on your income. If you are a married couple filing jointly with taxable income under $94,050 in 2026, your federal long-term capital gains rate is 0%. That means if your gain on the inherited home is under roughly $94,000, you pay zero federal capital gains tax before the step-up even matters. Combine the step-up with the 0% federal bracket, and most heirs walking away from a probate sale in North Jersey owe zero federal tax and a very small amount of New Jersey tax on the small gain above the stepped-up basis.

When the Step-Up Does Not Apply

There are two situations where the step-up in basis does not protect you. The first is when the property was owned jointly with right of survivorship by someone who is not your spouse. If you and your sibling jointly owned a property with your parent and your parent passed away, your basis in the portion you owned before their death does not step up. Only the portion that passes through the estate gets the step-up. If you and your parent owned the property as joint tenants and your parent died, your basis in the half you already owned is what you originally paid for it. Your basis in the half you inherited steps up to the date of death value. You end up with a blended basis that is higher than the original purchase price but lower than a full step-up.

The second situation is when the property was gifted during the decedent's lifetime rather than inherited through the estate. If your parent gave you the house as a gift five years before they passed away, your basis carries over from their original purchase price. There is no step-up because the transfer happened during their lifetime. This is a common trap. A parent adds an adult child to the deed to avoid probate, thinking they are doing the right thing. But if the parent and child hold the property as joint tenants with right of survivorship, only half the property gets the step-up. The other half retains the original basis. If the parent had kept the property in their name alone and let it pass through probate, the child would get a full step-up on 100% of the property. I see this mistake regularly. Before you add anyone to your deed, talk to an estate attorney about the tax implications. The probate savings might not be worth the capital gains cost.

The Step-Up and the Section 121 Exclusion: Can You Use Both?

If the heir moves into the inherited home and makes it their primary residence for at least 24 months before selling, they qualify for both the step-up in basis AND the Section 121 primary residence exclusion. Section 121 allows single filers to exclude up to $250,000 of gain on the sale of their primary residence, and married couples filing jointly to exclude up to $500,000. Here is how the two benefits stack. You inherit a home with a stepped-up basis of $500,000. You move in and live there for two years. The home appreciates to $620,000. Your gain is $120,000. If you are single, the Section 121 exclusion covers the entire $120,000 gain. You owe zero capital gains tax. If you are married, the $500,000 exclusion covers the gain easily. The step-up eliminates the pre-inheritance appreciation. The Section 121 exclusion eliminates the post-inheritance appreciation. Together, they make the sale of an inherited home completely tax-free for most families.

You cannot use the Section 121 exclusion if you never live in the home. If you inherit a home and sell it immediately or within a few months, you rely solely on the step-up in basis to eliminate the pre-inheritance gain. The post-inheritance gain is small if you sell quickly, so the tax is usually minimal. But if the home appreciates significantly after you inherit it and you never live in it, that post-inheritance gain is taxable. If the home was worth $500,000 when you inherited it and you sell it three years later for $650,000 after renting it out, your gain is $150,000 and it is fully taxable as a capital gain. The step-up protected you from the pre-inheritance appreciation, but the post-inheritance appreciation is on you.

How to Make Sure You Get the Full Step-Up

Getting the full benefit of the step-up depends entirely on having a documented date of death value. Without an appraisal or a broker's opinion of value dated to the date of death, the IRS can argue that the value was lower than what you claim, which increases your gain and your tax. Here is the process. As soon as the executor receives Letters Testamentary, they should order a retrospective appraisal from a licensed appraiser who is familiar with the North Jersey market. The appraiser values the property as of the date of death, using comparable sales from that period. The cost of a retrospective appraisal is typically $500 to $800 for a single-family home in Passaic or Bergen County. That is a small price to pay for documentation that can save you tens of thousands of dollars in taxes. If the home sells within a few months of the date of death and the sale price is close to the appraised value, the appraisal and the HUD-1 settlement statement together serve as your documentation. Keep both in your tax records. If the home sells more than six months after the date of death, the appraisal becomes even more important because the market may have moved and the sale price may not reflect the date of death value as clearly.

If the executor did not order an appraisal before the sale, you can still get a retrospective appraisal after the fact. The appraiser will use comparable sales from the period around the date of death to reconstruct the value. The IRS accepts retrospective appraisals as long as they are prepared by a qualified professional using accepted valuation methods. Do not try to estimate the date of death value yourself using Zillow or online estimators. The IRS will not accept them, and if you are audited, you will owe tax plus penalties and interest on any gain the IRS recharacterizes.

The Bottom Line

If you inherit a home in Passaic or Bergen County and sell it within a reasonable time, you will almost certainly owe little to no federal capital gains tax. The step-up in basis eliminates the decades of appreciation that happened before the decedent's death. Your gain is measured only from the date of death value forward, and on most properties the gain between the date of death and the sale date is small. Get a professional appraisal at the date of death value. Keep it with your tax records. Do not assume you owe a huge tax bill because your parents bought the house for $80,000 in 1985 and it is now worth $600,000. That $520,000 of appreciation is not your gain. It was never taxed. That is the step-up, and it was designed exactly for this situation.

I have walked dozens of families through this process in Clifton, Paterson, Passaic, Totowa, Woodland Park, Haledon, and Garfield. I know which appraisers understand the North Jersey market, how to coordinate the date of death valuation with the inheritance tax waiver process, and how to structure the sale so you walk away with the clearest tax picture possible.
