# Cambridge Seller Closing Costs: What the MA Excise Tax Actually Costs You
What are the key takeaways?
•The direct answer: Per the Middlesex South Registry of Deeds — the office where Cambridge deeds are recorded — the Massachusetts deeds excise is $4.56 per $1,000 of sale price, so a $1,250,000 sale carries about $5,700. It's customarily a seller-side line on the closing statement, but confirm with your closing attorney.
•The myth: The state excise tax is the big unknown that's going to eat into your proceeds.
•The reality: Per MA Loan Experts' 2026 Massachusetts closing-cost guide, total seller closing costs typically run 2% to 5% of the price — about $25,000 to $62,500 on a $1.25M sale. The excise is just one line inside that total, not an extra on top. The real bite comes from brokerage compensation — the commission you agree to pay your agent and, where applicable, the buyer's agent.
•The bottom line: Pull your mortgage payoff first, multiply your target price by 0.00456 for the excise, then get written quotes for everything else.
Why do Cambridge sellers worry about the wrong number?
I get this call every September. A Cambridge homeowner starts thinking about a fall listing, and the first question out of their mouth is about the excise tax. It sounds ominous — a state tax just for selling your own home.
Here's the reassuring part. Your deed gets recorded at the Middlesex South Registry of Deeds, right here in Cambridge, and its published rule is $4.56 per $1,000 of sale price, or any fraction of $1,000. Nothing's owed on transfers under $100. Work it out and that's 0.456%.
So on a $1,250,000 sale, the math is simple:
1,250 × $4.56 = $5,700
Massachusetts Deed Excise Rule for Middlesex South Sales
Primary-source card explaining the deed excise rate and the minimum consideration threshold listed by the Middlesex South Registry of Deeds.
| Category | Deed excise rule |
|---|---|
| Effective tax rate | $4.56 per $1000 or fraction thereof of taxable value |
| Minimum consideration below which no excise tax is due | $100.00 |
That's why the excise deserves a spot near the top of your net sheet — the one-page estimate of what you actually walk away with. It's fixed, it's non-negotiable, and you can calculate it before you even pick a list price.
The bigger issue is everything else. Per MA Loan Experts' 2026 Massachusetts closing-cost guide, total seller closing costs usually run 2% to 5% of the sale price — roughly $25,000 to $62,500 on a $1.25M sale. The excise sits inside that range: the small, knowable slice of a much larger and far more variable bill.
The excise is the most predictable line on your Cambridge net sheet. Budget it, then focus on the costs that can actually move.
How is the Massachusetts deeds excise tax calculated?
You multiply your price by the rate the recording office publishes. Per the Middlesex South Registry of Deeds, that rate is $4.56 per $1,000 or fraction thereof. Whatever price you're expecting, multiply it by 0.00456.
No municipal transfer fee stacks on top today. Per MA Loan Experts, no Massachusetts municipality levies one. Rules can shift, so confirm current rules with your attorney before you set a price. And if some online calculator tacks on a "Cambridge transfer fee," have your attorney verify it — that's not a charge your closing team should be assuming exists.
What does a Cambridge seller net sheet actually include?
Start with your gross sale price, then subtract what comes out at closing.
For most Cambridge sellers, the largest single deduction isn't a closing cost at all — it's the mortgage payoff. Pull your exact payoff balance from your lender first. Without that number, every net estimate you build is just a guess.
Then come the closing lines:
•Brokerage compensation — the commission you agree to pay your agent and, where applicable, the buyer's agent. Negotiated, and usually the largest closing-cost line.
•Massachusetts deeds excise — about $5,700 on a $1.25M sale, at the Registry rate above.
•Seller-side attorney fee — get it quoted in writing before you list.
•Smoke detector and carbon monoxide alarm certificate — confirm the current requirement and fee with your closing attorney.
•Municipal lien certificate — a city document confirming you owe no unpaid water, sewer, or tax bills — plus a final water/sewer reading and recording fees at Middlesex South.
•For condo sellers: the 6(d) certificate — a letter from your condo association confirming your fees are paid up — the condo document package, and pro-rated condo fees.
•Pro-rated property taxes — you pay only for the days you owned the home. Ask your attorney to compute your share from your actual tax bill.
Recording itself is modest. The Middlesex South fee schedule shows a deed records for $155, a mortgage discharge for $105, and a municipal lien certificate for $80.

What are the strongest objections to this way of looking at seller costs?
"The excise tax is a distraction. The agent commission is the real cost."
Fair point. At the 2% to 5% total range MA Loan Experts cites, commission typically accounts for most of that $25,000 to $62,500 — many multiples of the $5,700 excise. That's exactly why you should budget the full range rather than fixate on the tax alone, and why commission, being negotiable, is where asking the right questions actually moves your net. The excise still earns its own line simply because it's the one cost you can calculate exactly, today.
"Some sources publish a different rate."
They do, and the gap is wide enough to matter. Certain published closing-cost guides list a materially lower Massachusetts excise rate than the Registry's, often stated in a different unit — enough to misstate your line by thousands of dollars. Trust the Registry figure. Middlesex South is the office that actually computes and collects the excise when your Cambridge deed gets recorded. If a quote you receive uses a lower rate, have your attorney confirm it against that published schedule before relying on it.
"Could Cambridge add a local transfer fee later?"
It could, and this concession is real: in Massachusetts, excise and recording schedules are published jurisdiction by jurisdiction, so what gets charged on a transfer does vary by where the deed is recorded. That's exactly why your Cambridge number should come from the Middlesex South schedule rather than a statewide calculator — and why a future local add-on is worth confirming with your attorney rather than assuming away. Today, per MA Loan Experts, no Massachusetts municipality levies such a fee, so nothing's layered onto your excise line. Predictable today doesn't mean permanent.
How should you build your net sheet before listing?
Do this before you settle on a final list price.
1. Pull your exact mortgage payoff from your lender.
2. Multiply your target price by 0.00456 for the excise.
3. Get written attorney and closing-cost quotes — not verbal estimates.
4. Order the municipal lien certificate and smoke/CO inspection early.
Then run two versions: one at your target list price, one at 3% under. The second shows what your net looks like if negotiations get tougher than expected.
The gap between the 2% and 5% closing-cost range is where most surprises live. The excise usually isn't one of them.
If you're considering a Cambridge sale this fall, send me your estimated price range and mortgage payoff. I'll help you map the real net before you commit to a listing strategy.
