# Massachusetts' New $1M Nonresident Withholding Rule: What Sellers and 1031 Investors Need to Know Statewide
Key Takeaways
•The 4% default isn't your only option. Nonresident individuals can elect a net-gain rate of 5% of estimated gain, which often holds back less cash at closing — though it does not reduce any separate surtax you may owe.
•The trigger is $1 million and up. Any Massachusetts home sale with a gross price of $1,000,000 or more by a nonresident is covered, statewide, under a recent Massachusetts Department of Revenue regulation.
•The bottom line: run both calculations before you sign. Long-held, high-basis homes usually win with the net-gain election — but recent purchases with little appreciation are the clear exception, and you must claim your choice on the Transferor's Certification before closing.
•1031 investors get relief, but only if the exemption is documented on that same certification. Silence is never an exemption.
Selling Massachusetts real estate from out of state? This rule can feel like a surprise cash grab at closing.
You may hear "4% withholding" and assume the state will automatically take 4% of your full sale price. That can happen — but it's not your only option.
Under Massachusetts Department of Revenue regulation 830 CMR 62B.2.4, withholding is required on nonresident sales of Massachusetts real estate priced at $1,000,000 or more statewide, effective November 1, 2025. The state wants to collect income or corporate tax from sellers who may not live here anymore.

This is no longer a brand-new closing issue. It's run through a full selling season, and attorneys and title companies are applying it statewide, including in Newton, Needham, and Natick, where seven-figure sales are common.
Are You Actually a Nonresident Under This Rule?
Start here before you worry about the numbers, and confirm your residency status with your closing attorney. Generally, you're a Massachusetts resident if you're domiciled here. You also count as a resident if you keep a home here and spend more than 183 days in the state during the year.
A full-year resident is exempt — someone who's a resident from January 1 through closing and stays one afterward. Nonresidents may include out-of-state owners, part-year residents, and business entities with no continuing Massachusetts presence; confirm the current rules with your agent.
Here's the practical trap:
Even exempt sellers still need to file a Transferor's Certification at closing to claim the exemption. Silence is not an exemption.
So if you moved from Newton to Florida last year but still own the family home, you may be covered. Sell in Needham while staying in Massachusetts, and you may be exempt — but you still need the paperwork.
Can the Net-Gain Election Reduce Your Withholding?
Yes, and this is where many sellers can save cash at closing.
There are two ways to calculate the withholding. The default method is 4% of the full gross sale price. It doesn't care what you actually made.
Personal Income Taxpayer Withholding Rate Options
Comparison of the percentage rates that can apply to individual sellers subject to Massachusetts personal income tax withholding.
| Series | Label | Value |
|---|---|---|
| Withholding rate | Rate on gross sales price (personal income taxpayers) | 4% |
| Withholding rate | Rate on estimated net gain (alternative withholding election) | 5% |
| Withholding rate | Additional surtax on amount over surtax threshold (personal income taxpayers) | additional 4% |
For personal income taxpayers, the net-gain election uses your estimated profit instead, at 5% of estimated net gain. An additional 4% surtax may apply above the surtax threshold.
In plain English, net gain means: sale price, minus original purchase price, minus improvements, minus brokerage commission, minus closing costs. That difference matters, because the tax base can be far smaller than the full price. Savings depend heavily on your basis — roughly what you originally paid plus improvements — so gain-to-price ratios vary widely from seller to seller.
The regulation's own example shows the mechanic. A seller's $1,200,000 share of the price, reduced by a $640,000 basis, leaves a $560,000 net gain. Withholding is 5% of that gain, or $28,000.

| Series | Label | Value |
|---|---|---|
| Taxpayer B dollar amounts | Taxpayer B's share of Gross Sales Price | $1,200,000 |
| Taxpayer B dollar amounts | Taxpayer B's Estimated Adjusted Basis (stated) | $640,000 |
| Taxpayer B dollar amounts | Taxpayer B's Estimated Net Gain (stated as $1,200,000 - $640,000) | $560,000 |
| Taxpayer B dollar amounts | Taxpayer B withholding amount (calculation noted as $560,000 × 5%) | $28,000 |
Practice guidance from Harris Beach Murtha notes that the net-gain method "is primarily utilized because the tax amount tends to be less than the Default Tax Rate."
One more layer matters for higher-gain sellers: gain above the 2026 millionaire's surtax threshold of $1,107,950, per the Hopkinton Independent's reporting on the DOR rules, carries an extra 4% surtax. That surtax is separate from — and additive to — withholding. The election may lower what's held back at closing, but it doesn't erase the surtax, so model both before you sign.
To elect the net-gain method, you need records supporting your estimate, and you must choose it on the Transferor's Certification before closing. This isn't something to clean up casually after the deed records.
When Might the Net-Gain Election Not Help You?
The net-gain election is powerful, but it's not automatic. Three common concerns are worth taking seriously.
"What if I bought recently and have very little appreciation?"
Then the default may serve you better. This is exactly the case where the net-gain election doesn't win — which is why it's an election, not a requirement. Run both calculations before you choose.
"What if I still owe the 4% surtax?"
Withholding and surtax aren't the same thing. Withholding is money prepaid at closing; the surtax is an added tax on net capital gains above the threshold. The election may reduce what's held back now, but it doesn't erase the surtax.
"What if my net gain estimate is hard to prove?"
That's a real issue. Sellers can use an estimated net-gain basis, and the settlement agent files Form NRW within 10 days. Work with your closing attorney and CPA to confirm what records they want before you get to the table.
How Does the 1031 Exchange Exemption Work in Massachusetts?
If you're doing a 1031 exchange, this rule deserves extra attention.
A like-kind exchange under Section 1031 can qualify for a full or partial exemption from withholding, because a valid exchange defers the gain, leaving little or no current Massachusetts tax to secure. But the exemption isn't automatic. Confirm the current rules with your agent, and claim it on the Transferor's Certification. If the certification stays silent, the closing team may withhold anyway.
A few edge cases matter:
•Spousal transfers qualify for exemption.
•Single-member LLCs do not get the pass-through entity exemption.
•Part-year residents must review the residency rules carefully.
For investors, this really comes down to cash flow and timing. Over-withheld amounts are recoverable later by filing a nonresident return, so it's a liquidity issue, not a permanent loss. But "later" doesn't help if you need that money now to fund replacement property within your 1031 timeline. That timing risk matters for multifamily and rental investors across Natick, MetroWest, and Greater Boston, where seven-figure deals are routine.
What Should You Do Before Closing?
This rule rewards early planning. Use this checklist before you sign the purchase and sale agreement:
1. Check your residency status. Review domicile and the 183-day rule before you list.
2. Gather net-gain records now. Pull purchase records, improvement receipts, commission estimates, and closing-cost estimates.
3. Run both withholding methods. Compare the 4% default against the net-gain election with your attorney or CPA.
4. Complete the Transferor's Certification before closing. This is where you claim an exemption or elect net-gain treatment.
5. Understand the follow-up. Your settlement agent remits the withholding to DOR within 10 days. You'll receive a DOR withholding statement the following January, then file Form 1-NR/PY to settle up.
The local price point makes this urgent. In Newton, the median sale price sits around $1.5 million — well above the threshold — with homes selling in 34 days at 98.5% of asking.

For many sellers, this won't be a rare edge case — it'll be a standard part of a high-value Massachusetts closing.
Over-withholding isn't lost money, but it is your cash tied up for months when you may need it most, right at closing. If you're selling from out of state or planning a 1031 exchange, ask your attorney, CPA, or local advisor to run both the default and net-gain scenarios before you set a closing date.
