Understanding Massachusetts’ New Transferor’s Certification Form: What Sellers Need to Know

If you're preparing to sell a home here in Massachusetts — especially along the South Shore — there’s a new piece of paperwork to be aware of: the Transferor’s Certification Form, introduced by the Massachusetts Department of Revenue (DOR).

As of November 1, 2025, this form becomes a required step for certain Massachusetts real-estate transactions — specifically those where the gross sales price is $1,000,000 or more.

Before you worry: this isn’t a brand-new tax on home sellers. It’s simply a new way for the Commonwealth to collect taxes already owed on capital gains. As your local REALTOR® — I’m Bill Tierney of William Raveis Real Estate in Scituate, MA — I want to help you understand what this form means, when it applies, and how to handle it smoothly before closing.

Key Takeaways

• The Transferor’s Certification Form must be completed for any Massachusetts real-estate sale of $1 million or more that closes on or after November 1, 2025.
• This form does not impose a new tax — it simply helps the DOR collect capital gains tax that sellers already owe.
• Residency matters: in-state sellers typically just file the form, while out-of-state sellers may have taxes withheld.
• The 4% maximum withholding acts as a prepayment of tax, not an additional cost.
• Plan ahead: involve your attorney and accountant early to prevent delays at closing.

What is the Massachusetts Transferor’s Certification Form?

This new form verifies important information about the seller (transferor) — such as their residency status, ownership structure, and taxpayer ID — so the DOR can confirm whether Massachusetts tax should be withheld from the sale proceeds.

Think of it as the Commonwealth’s version of a W-2 for your home sale. It’s paperwork for tracking taxes, not a new charge on your transaction.

Previously, only nonresident sellers faced automatic withholding. Under the new system, all sellers of properties priced at $1 million or more must complete the form before the deed can be recorded.

How Tax Withholding Works Under the New Rules

When you sell property in Massachusetts, any gain (sale price minus your original cost and related expenses) is subject to Massachusetts income tax. The Transferor’s Certification Form helps ensure that this tax gets collected properly.

What “Withholding” Means

Withholding isn’t a new fee — it’s a prepayment of the tax you already owe. The closing attorney may be required to send a portion of the proceeds directly to the DOR. Later, when you file your tax return, the amount withheld is credited toward your total tax due.

How It’s Calculated

For nonresident sellers, Massachusetts requires that up to 4% of the sale price or the taxable gain (whichever is less) be withheld and remitted to the DOR.

Example 1 – Massachusetts Resident Seller

• Sale price: $1,300,000
• Original purchase price: $800,000
• Gain: $500,000

If you’re a Massachusetts resident, you’ll report that gain on your next state tax return and pay the 5% capital-gains tax then. No withholding typically occurs at closing — but the form is still required.

Example 2 – Out-of-State Seller

• Sale price: $1,300,000
• Original purchase price: $800,000
• Gain: $500,000

If you live outside Massachusetts, the closing attorney will likely withhold 4% of the $500,000 gain ($20,000) and send it to the DOR. When you file your nonresident return, you’ll reconcile that prepayment — possibly receiving a refund if too much was withheld.

How the Rules Differ for Massachusetts Residents vs. Out-of-State Sellers

For Massachusetts Residents

If Massachusetts is your primary residence, this form is mainly about documentation.

• You’ll complete the form to confirm your residency.
• No withholding will be taken from your proceeds.
• You’ll report your gain on your Massachusetts return as usual.

For Out-of-State Sellers

If you live elsewhere but are selling Massachusetts property, the closing attorney must withhold up to 4% of the sale price or gain. This acts as a tax prepayment and ensures compliance.

Why the Change?

The DOR introduced this process to improve tax compliance on high-value real-estate transactions — particularly from nonresidents — and to simplify record-keeping for all sellers.

The $1 Million Threshold — Why It Matters

The rule applies only to transactions with a sale price of $1,000,000 or more.

If Your Sale is Under $1 Million

The new form generally doesn’t apply. You’ll still handle capital-gains taxes at filing time, but your closing won’t require the Transferor’s Certification Form.

If Your Sale is Over $1 Million

The form becomes mandatory. Resident sellers complete it for documentation; nonresidents may see up to 4% withholding at closing.

Local Impact: South Shore Examples

• Luxury Listings (Cohasset, Hingham, Duxbury): Many homes exceed $1 million, so this form is now standard closing paperwork.
• Midrange Homes (Scituate, Marshfield, Norwell): Often below $1 million, so sellers may not need to worry about the form — but should confirm with their attorney.
• Out-of-State Owners: If you own a second home or rental property here, expect withholding if the sale exceeds $1 million.

The bottom line: the threshold marks which sellers are affected — it’s about compliance, not a new tax burden.
