You’ve probably heard the rumors or seen the frantic headlines. Boston homeowners are staring down a massive property tax spike. It’s not just a few bucks, either. Honestly, if you live in a single-family home in the city, your bill is likely jumping by about 13% this year. That’s roughly $780 more for the "average" house, according to the latest figures from City Hall.
Why is this happening now? Basically, it’s a perfect storm of post-pandemic office vacancies and state-level politics. For decades, Boston has leaned on commercial skyscrapers to pay the lion's share of the bills. But with more people working from home and office values tanking—they dropped about 6% recently—the math doesn't work like it used to. The burden is shifting. It's shifting right onto your front porch.
The Real Tax Rate for Boston MA Right Now
Let's talk numbers. For Fiscal Year 2026 (which runs from July 2025 through June 2026), the residential tax rate is set at $12.40 per $1,000 of assessed value.
Compared to last year’s $11.58, it’s a significant climb. If you own a business or commercial property, the rate is much steeper: **$26.96 per $1,000**.
Breaking Down the Split
Boston uses a "split tax rate." This is a mechanism where the city intentionally charges commercial owners more to keep residential bills lower. Under Massachusetts law, the city can usually only shift this burden up to 175%. Mayor Michelle Wu tried to push that limit even higher—up to 181.5%—to protect homeowners from this year’s "tax shock."

However, the state Senate recently killed that plan again in mid-January 2026. Because that legislative "shield" failed, the city had to move forward with the $12.40 rate. Without that shift, the city says the increase would have been even more painful.
Why Your Bill Feels Higher Than the Rate Suggests
A tax rate is just one half of the equation. The other half is your assessment.
Massachusetts law requires the city to assess property at "full and fair cash value." For the 2026 tax year, the city looked at what homes were worth as of January 1, 2025. Even though the commercial market is struggling, residential values in Boston rose by about 2%.
So, you’re getting hit twice:
- The rate per thousand dollars went up.
- The number of "thousands" your home is worth also went up.
This explains why some residents are seeing their January 2026 and May 2026 bills look so much heavier. Since the new rates are finalized mid-fiscal year, the entire increase for the year often gets compressed into the third and fourth quarter bills. It’s a literal "sticker shock" when you open that envelope.
The Residential Exemption: Your Only Real Defense
If you live in the home you own, you need to make sure you have the Residential Exemption. This is arguably the most important tax break in the city.
For Fiscal Year 2026, the exemption is worth $4,353.74.
Basically, the city takes a chunk of your home's value (around $351,108 this year) and says, "We won't tax you on this part." To qualify, the property must be your principal residence. You had to own and occupy it as of January 1, 2025, for the current cycle.
How to get it
- Deadline: You have until April 1, 2026, to apply for the current fiscal year.
- Where: You can file through the Boston Assessing Department at City Hall.
- Check your bill: Look at your third-quarter bill (the one that arrived in late December/early January). If you don't see a credit for the exemption, you’re leaving over four thousand dollars on the table.
Commercial Values and the "Office Apocalypse"
We can't talk about the tax rate for Boston MA without mentioning the skyscrapers downtown. For a long time, commercial property accounted for about 60% of Boston's tax revenue despite making up only a third of the property value.
That's changing.
With Class A office values dropping, the city is losing its biggest piggy bank. Mayor Wu’s administration has been vocal about this. They argue that if the state doesn't allow a temporary "over-shift" of taxes onto commercial owners, residents will face double-digit increases for years to come.
Critics, including the Greater Boston Chamber of Commerce and some state senators, argue that hiking commercial rates even higher will just drive more businesses out of the city. They worry it creates a "death spiral" where higher taxes lead to more vacancies, which leads to even higher taxes for those who stay. It’s a messy, high-stakes debate that isn't over yet.
What About Sales and Income Tax?
While property tax is the big local variable, don't forget the state-level bites.
- Sales Tax: Still 6.25%. Boston doesn't add a local sales tax on top of the state rate, unlike some other major U.S. cities.
- Income Tax: The flat rate is 5.0%. However, if you're a high earner (making over $1 million), the "Millionaire's Tax" (a 4% surtax) applies to the portion of your income above that million-dollar threshold.
Challenging Your Bill: The Abatement Process
If you think the city has your home's value wrong, you aren't stuck. You can file for an abatement.
But you have to be fast. The window to file for an abatement starts when the third-quarter tax bills are mailed (late December) and ends on February 2, 2026.
To win an abatement, you generally need to prove one of three things:

- Overvaluation: You couldn't actually sell your house for what the city says it's worth.
- Disproportionate Assessment: Your house is assessed way higher than identical houses on your street.
- Misclassification: They have you listed as a three-family when you’re a two-family, or commercial instead of residential.
Just a heads-up: simply "thinking taxes are too high" isn't a legal reason for an abatement. You need data, like recent sales of similar homes in your neighborhood.
Practical Next Steps for Boston Taxpayers
Don't just sit there and let the bill hit you. There are a few things you should do right now to manage the 2026 tax hike.
First, verify your exemption. Open your most recent bill and look for the "Residential Exemption" line item. If it isn't there and you live in the house, call the Assessing Department at 617-635-4287 immediately.
Second, adjust your escrow. If you pay taxes through your mortgage, your monthly payment is going to go up. Your bank might not catch the 13% hike until their annual escrow analysis. You can call them now and ask to increase your monthly withholding so you don't end up with a massive "escrow shortage" payment next year.
Third, watch the assessments. The value of your home as of January 1, 2026, will determine your taxes for next year (FY2027). If you’ve done major renovations, expect a jump. If the market in your specific neighborhood has cooled off, check that the city’s data reflects that reality.
Finally, keep an eye on the State House. Even though the tax shift bill failed in January 2026, the city is still looking for ways to provide relief. Senator Will Brownsberger has proposed a "tax shock" bill that would allow cities to shield vulnerable taxpayers (like seniors on fixed incomes) if their bills jump by more than 10%. That legislation is still moving through the pipes and could offer a lifeline for some.
