NJ Realty Transfer Fee and Mansion Tax Explained: What Every Bergen and Hudson County Seller Needs to Know

Selling your Bergen County or Hudson County home? Two fees that surprise most sellers are the NJ Realty Transfer Fee and the Mansion Tax. Here's exactly what they are, how much they cost, and how to prepare.

The NJ Realty Transfer Fee

What It Is

New Jersey charges a realty transfer fee on every property sale. It is a state tax, not negotiable, and it is paid by the seller at closing. The fee is based on the sale price and varies by municipality. Every seller in New Jersey pays this fee regardless of which town they live in.

How Much It Costs

The fee is structured in tiers based on the sale price of the home:

• Homes under $350,000: approximately $2 per $500 of consideration
• Homes between $350,000 and $1,000,000: higher tier rates apply
• Homes over $1,000,000: highest tier rates apply

For most Bergen County and Hudson County sellers, the typical range falls between $2,000 and $8,000. Here are some real-world examples:

• $400,000 home: approximately $2,000 to $3,000
• $600,000 home: approximately $4,000 to $5,000
• $800,000 home: approximately $5,000 to $6,000
• $1,200,000 home: approximately $7,000 to $8,000

How to Minimize It

You cannot avoid the realty transfer fee — it is a state tax, and New Jersey enforces it on every sale. But you can plan for it:

• Ask your attorney to calculate the exact amount before you list your home
• Factor it into your net proceeds calculation from day one
• Your attorney will reconcile the final number at closing
• Knowing the amount in advance prevents surprises at the settlement table

The Mansion Tax (1%)

What It Is

New Jersey imposes a 1% "mansion tax" on homes sold for over $1 million. This is in addition to the standard realty transfer fee. It is a flat 1% of the full sale price, paid by the seller at closing.

When It Applies

The mansion tax applies only when the sale price exceeds $1,000,000. For any home sold at $1 million or under, the mansion tax does not apply. The threshold is based on the contract sale price, not the assessed value or the appraised value.

How Much It Costs

At a flat 1% of the sale price, the mansion tax adds up quickly:

• $1,100,000 home: $11,000 mansion tax
• $1,200,000 home: $12,000 mansion tax
• $1,500,000 home: $15,000 mansion tax
• $2,000,000 home: $20,000 mansion tax

Important: These Costs Stack

The mansion tax is in ADDITION to the standard realty transfer fee. A $1.2 million home pays both the realty transfer fee (approximately $7,000 to $8,000) AND the mansion tax ($12,000). The total in transfer taxes alone for that sale: approximately $19,000 to $20,000.

This is the number that surprises most luxury sellers. They expect the realty transfer fee. They do not expect it to nearly double.

Combined Cost Examples

Here is how these fees play out across three real-world price points in Bergen and Hudson Counties:

Example 1: $500,000 Condo

• Realty Transfer Fee: approximately $3,000
• Mansion Tax: $0 (under $1 million threshold)
• Total transfer taxes: approximately $3,000

Example 2: $750,000 Single Family

• Realty Transfer Fee: approximately $5,000
• Mansion Tax: $0 (under $1 million threshold)
• Total transfer taxes: approximately $5,000

Example 3: $1,200,000 Luxury Home

• Realty Transfer Fee: approximately $7,500
• Mansion Tax (1%): $12,000
• Total transfer taxes: approximately $19,500

Notice the jump. A seller moving from a $750,000 home to a $1.2 million home does not just pay a larger realty transfer fee — they suddenly owe nearly $20,000 in transfer taxes alone. That is a meaningful difference in net proceeds.

How to Plan for These Costs

1. Know the Numbers Before You List

Ask your attorney to calculate the exact realty transfer fee and mansion tax based on your expected sale price. Most lawyers will do this as part of their pre-listing consultation. If they do not offer, ask. It is a simple calculation, and having the number in advance lets you price your home with full awareness of your net proceeds.

2. Factor Into Net Proceeds

These fees come off the top at closing. When you calculate what you will actually walk away with, remember that the realty transfer fee and mansion tax are subtracted before you see a dollar. Every seller I work with gets a net proceeds worksheet before we list, so there are no surprises.

3. Price Strategically Near the Threshold

If your home is likely to sell in the $900,000 to $1,100,000 range, the $1 million mansion tax threshold becomes a strategic consideration. Pricing just under $1 million avoids the 1% mansion tax entirely. Pricing over $1 million triggers an additional $10,000+ in tax. The right strategy depends on your market, your home's value, and your timeline. An experienced agent can help you model both scenarios.

4. Work With an Agent Who Understands the Math

Not every agent runs these numbers for their sellers before listing. An experienced local agent will build the full cost picture into your pricing strategy from the beginning — including the realty transfer fee, the mansion tax, commission, and all other closing costs. See our complete closing costs guide for Bergen County for a full breakdown of what to expect.

How This Connects to the Condo Cliff

These transfer taxes are separate from the condo cliff changes, but they stack. If you are selling a condo that now faces Full Review, and you are paying realty transfer fees and potentially the mansion tax, the total cost of selling is higher than most sellers expect. The condo cliff changes that took effect August 3, 2026 add another layer of complexity for anyone selling in a building with 11 or more units.

This is why it is critical to understand ALL the costs before you list — not just the commission. If you are weighing whether to sell your condo or hold onto it, see our analysis on whether to sell or rent your Port Imperial condo.

The Bottom Line

The NJ Realty Transfer Fee is a cost every seller must plan for. The Mansion Tax adds a significant layer for anyone selling above $1 million. Neither is avoidable, but both are manageable with the right preparation and the right guidance.

The most important step: get your numbers early. Before you set an asking price, before you schedule a photographer, before you do any staging — know what your transfer taxes will be. That single number shapes your pricing strategy, your net proceeds, and your timeline.
