Massachusetts Form NRW is the nonresident real estate withholding return, filed electronically on MassTaxConnect whenever a nonresident sells Massachusetts real property for $1 million or more. The withholding agent, usually the closing attorney or buyer’s representative, completes the form and remits a percentage of the sale proceeds to the Massachusetts Department of Revenue before releasing funds to the seller. There is no paper version.
When Form NRW Is Required
Withholding applies to Massachusetts real estate sales of $1 million or more when the seller is a nonresident individual, trust, or entity without a tax home in the state. The withholding agent files Form NRW and remits the tax at closing. If a transaction has more than one seller, each seller is accounted for separately on the form.
The requirement does not apply when the seller is a government entity. Any other seller claiming an exemption or a reduced withholding amount must certify the basis for that treatment on a Transferor’s Certification, which the withholding agent uploads with Form NRW. Even when an exemption zeroes out the withholding, the form still has to be filed to document the transaction.1Massachusetts Department of Revenue.

Withholding Rates and the Net-Gain Alternative
The default withholding is 4% of the gross sales price, whether the seller pays personal income tax or corporate excise. Sellers can elect an alternative calculation that applies the rate to the estimated net gain rather than the full proceeds:
- Personal income tax sellers: 5% of estimated net gain.
- Corporate excise sellers: 8% of estimated net gain.
The alternative can lower the withholding substantially when the seller’s basis is high relative to the sales price. To use it, the seller certifies the estimated net gain on the Transferor’s Certification, and the withholding agent uses that figure to calculate the tax.
An additional 4% surtax applies to the portion of the gross sales price, or the estimated net gain if the alternative is elected, that exceeds the surtax threshold. For tax year 2025, that threshold is $1,083,150 for personal income taxpayers.2Mass.gov.

How to File on MassTaxConnect
Form NRW exists only as an electronic filing, so the withholding agent needs a MassTaxConnect account. Register well before closing; DOR takes several business days to activate a new account.
The form asks for three sets of information:
- Withholding agent details: name, address, and taxpayer identification number.
- Transaction details: closing date and gross sales price.
- Seller details: each nonresident seller’s name, identification number, and withholding amount. If a seller elected the alternative calculation, use the estimated net gain from that seller’s Transferor’s Certification.
After the data entry, MassTaxConnect shows a screen titled “Settlement Statement (HUD-1) and Transferor Certifications.” Upload the HUD-1 and a separate Transferor’s Certification for each seller. Multiple sellers means multiple certification uploads, one per seller.1Massachusetts Department of Revenue. Filing and Withholding Rules: Real Estate Sales of $1 Million or More
The Transferor’s Certification
The Transferor’s Certification belongs to the seller, not the withholding agent. On it, the seller attests to any exemption from withholding or any reduction, and a seller electing the net-gain alternative certifies the estimated gain figure. Every seller needs one, with the government-entity exception noted above. When a certification supports a full exemption, the withholding agent may reduce or eliminate withholding for that seller and still files Form NRW to document the deal.1Massachusetts Department of Revenue.

What the Seller Files After Closing
The amount withheld through Form NRW is a prepayment, not a final tax. A nonresident seller reports the gain on Form 1-NR/PY, the Massachusetts nonresident income tax return, and claims credit for the withheld amount. The return is due by April 15 of the year after the sale.3Massachusetts Department of Revenue. Form 1-NR/PY Instructions If withholding exceeded the actual tax, the seller gets a refund. If the tax is higher, the seller pays the difference with the return.
Not the Same as Performer Withholding
Form NRW is sometimes confused with Massachusetts’s withholding program for nonresident performers, athletes, and speakers. That program is separate, uses Forms PWH-WW and PWH-RW for waivers and reductions, and does not apply to real estate transactions.4Massachusetts Department of Revenue.
