Understanding the NYC Capital Gains Tax on Property Sales: A Guide for Homeowners

When you sell a property in New York City, it's not just about the sale price and the celebratory handshake. You'll likely encounter a number of taxes and fees, with the capital gains tax being one of the most significant. Unlike other closing costs, this is a tax on your profit, not the sale itself, and it's something every seller should understand.

At Yeo Real Estate, we believe in empowering our clients with knowledge. This guide will walk you through everything you need to know about capital gains tax on a property sale in NYC, from how it’s calculated to how you might be able to reduce your tax bill.


What is Capital Gains Tax?

Simply put, a capital gain is the profit you make from selling an asset. In real estate, it’s the difference between your property’s sale price (after deducting selling costs) and your adjusted cost basis (what you originally paid plus the cost of improvements).

Taxable Gain = Net Sale Price – Adjusted Cost Basis

There are two types of capital gains, which are determined by how long you owned the property:

  • Short-Term Capital Gain: From an asset you owned for one year or less. This is taxed at your ordinary income tax rate, which is typically higher.

  • Long-Term Capital Gain: From an asset you owned for more than one year. This is taxed at a more favorable rate.

In NYC, you will be subject to three separate capital gains taxes:

  • Federal Capital Gains Tax: The federal government imposes a long-term capital gains tax rate of 0%, 15%, or 20%, depending on your income level.

  • New York State Income Tax: New York State taxes capital gains as ordinary income, at rates ranging from 4% to 10.9%.

  • New York City Income Tax: Similarly, New York City taxes capital gains as ordinary income, with rates ranging from 3.078% to 3.876%.


How to Calculate Your Taxable Capital Gain

Calculating your taxable gain is a critical first step. It involves two main components: your net sale price and your adjusted cost basis.

Step 1: Determine Your Net Sale Price

This is your final sale price minus any eligible selling expenses. These expenses reduce your taxable gain and include:

  • Real estate broker commissions

  • Legal fees

  • Title insurance fees

  • Transfer taxes (more on this below)

  • Survey fees

Example:

  • Sale Price: $1,200,000

  • Selling Expenses: ($70,000 in broker fees + $2,500 in legal fees + $22,000 in transfer taxes) = $94,500

  • Net Sale Price: $1,200,000 - $94,500 = $1,105,500

Step 2: Determine Your Adjusted Cost Basis

Your cost basis is what you originally paid for the property, plus the cost of any significant capital improvements you made while you owned it. These improvements must add value, prolong the life of the property, or adapt it to a new use. Examples include:

  • Adding a new room or a deck

  • Installing a new roof or a central air conditioning system

  • Upgrading an electrical system

  • Replacing all windows

  • Finishing a basement or attic

Routine repairs and maintenance, such as painting a room or fixing a faucet, do not count. It is crucial to keep meticulous records and receipts for all improvements.

Example:

  • Purchase Price: $750,000

  • Closing Costs (legal fees, mortgage recording tax, etc.): $15,000

  • Capital Improvements (kitchen remodel, new windows): $75,000

  • Adjusted Cost Basis: $750,000 + $15,000 + $75,000 = $840,000

Step 3: Calculate Your Gain

Subtract your adjusted cost basis from your net sale price.

Example:

  • Net Sale Price: $1,105,500

  • Adjusted Cost Basis: $840,000

  • Total Capital Gain: $1,105,500 - $840,000 = $265,500

This is the amount of your profit before any exclusions or exemptions.


Key Questions & Answers for NYC Sellers

What is the Primary Residence Exclusion (Section 121)?

This is the most powerful tool for homeowners to reduce their capital gains tax. If the property you’re selling has been your primary residence for at least two of the last five years, you can exclude a significant portion of your capital gain from taxation:

  • Single filers: Can exclude up to $250,000 of the gain.

  • Married couples filing jointly: Can exclude up to $500,000 of the gain.

If your gain is below these thresholds, you may not owe any federal capital gains tax at all. New York State and New York City also recognize this exclusion.

What if I’m selling an investment property?

The rules are different for investment properties, such as rental units. You are not eligible for the primary residence exclusion. Additionally, you must consider depreciation recapture.

If you claimed depreciation deductions on your tax returns while owning the rental property, the IRS will tax that portion of your gain at a higher rate (up to 25% federally).

For investment properties, the most common way to defer capital gains tax is through a 1031 Exchange. This allows you to reinvest the proceeds from your sale into a "like-kind" property, thereby deferring your capital gains tax until a later date.


Understanding the Difference: Capital Gains vs. Other NYC Taxes

Sellers often confuse capital gains tax with other fees and taxes. It's important to know the difference.

Tax/Fee

What It Is

Who Pays It

Is It a Capital Gains Tax?

Real Property Transfer Tax (RPTT)

A tax on the transfer of real property. The rate depends on the sale price.

The seller is generally responsible for paying the tax.

No. This is a transfer tax paid at closing, not a tax on your profit. It is, however, an eligible selling expense that can be used to lower your taxable gain.

NYC Mansion Tax

An additional transfer tax on residential properties that sell for $1 million or more.

The buyer.

No. This is a buyer's tax and does not affect the seller's capital gains calculation.

Flip Tax

A fee charged by a co-op or condo building on the sale of a unit.

Typically the seller.

No. This is a building-specific fee, not a government tax. It is also an eligible selling expense that can reduce your capital gain.


Tips & Takeaways for a Seamless Sale

  1. Keep Meticulous Records: Save every receipt for major home improvements, closing costs from your original purchase, and selling expenses. This is the single best way to ensure your adjusted cost basis is as high as possible, thereby reducing your taxable gain.

  2. Consult a Tax Professional: Real estate transactions are complex. A qualified tax advisor can help you navigate your specific situation, maximize your deductions, and plan for your tax liability well before the closing date.

  3. Understand Your Eligibility: Before listing your property, determine if you are eligible for the primary residence exclusion. This can dramatically impact your net proceeds. If you are selling an investment property, a 1031 Exchange may be a good strategy to explore.

Navigating the tax implications of a property sale is a crucial part of the process. At Yeo Real Estate, we're not just here to sell your property; we're here to guide you through every step, from pricing strategies to understanding your financial obligations.
