Understanding New Jersey Capital Gains Tax
New Jersey does not have a separate tax rate for capital gains. Instead, capital gains are treated as ordinary income and are subject to New Jersey's state income tax rates. This means that the profit you make from selling an asset (like stocks, bonds, real estate, or other property) is added to your other income, and the total is taxed according to the state's progressive income tax brackets.
How Capital Gains are Calculated
The fundamental calculation for a capital gain is straightforward:
Capital Gain = Selling Price - (Purchase Price + Costs of Sale)
For assets like real estate or business equipment, you may also need to account for depreciation. Depreciation effectively reduces your cost basis over time, meaning when you sell the asset, a portion of the gain might be due to depreciation recapture, which is taxed as ordinary income.
Cost Basis: This includes the original purchase price of the asset plus any non-deductible costs associated with its purchase and improvements made to it.
Selling Expenses: These are costs incurred when selling the asset, such as real estate agent commissions, legal fees, advertising costs, etc.
Depreciation: If you've claimed depreciation deductions on the asset (e.g., for a rental property), this amount is subtracted from your cost basis. When the asset is sold, the amount of depreciation claimed is often "recaptured" and taxed as ordinary income, rather than potentially lower long-term capital gains rates if they existed separately. In New Jersey, this recapture is simply taxed at your ordinary income tax rate.
Therefore, the Taxable Capital Gain for New Jersey purposes is:
Taxable Capital Gain = Selling Price - Purchase Price - Depreciation Claimed - Selling Expenses
Our calculator simplifies this by focusing on Purchase Price, Selling Price, and Depreciation. Selling expenses can be factored into the cost basis calculation or subtracted directly. The resulting gain is then added to your other New Jersey income.
New Jersey Income Tax Brackets and Capital Gains
New Jersey has a progressive income tax system, meaning higher income levels are taxed at higher rates. As of the 2023 tax year, the marginal tax rates range from 1.4% to 10.75%. When you have a capital gain, it increases your total taxable income. The tax on that capital gain is determined by the highest marginal tax bracket your total income reaches.
For example, if your total New Jersey income (including the capital gain) pushes you into the 6.37% tax bracket, your capital gains will be taxed at that rate. If it pushes you into the top 10.75% bracket, your gains will be taxed at that higher rate. This calculator estimates the tax based on the marginal rate applicable to your total income.
Key Considerations for New Jersey Capital Gains:
No Separate Capital Gains Rate: Remember, gains are taxed as ordinary income.
Short-Term vs. Long-Term: Unlike federal tax law, New Jersey does not distinguish between short-term and long-term capital gains for tax rate purposes. Both are taxed at the same ordinary income rates.
Depreciation Recapture: Gains attributable to depreciation claimed on certain assets (like real property used in a business or for rent) are taxed as ordinary income.
Exemptions and Exclusions: Certain assets might have specific exclusions or different treatment. For example, gains from the sale of New Jersey municipal bonds are generally exempt from NJ income tax.
Filing Requirements: You must report all capital gains on your New Jersey income tax return (Form NJ-1040).
Tax Law Changes: Tax laws and brackets can change annually. Consult the latest New Jersey Division of Taxation guidelines or a tax professional for the most current information.
