You found a house in Marion for $750,000. You looked up the tax rate, did quick math, and felt pretty good. Then you closed, got your first water bill from the Sippican Water District, and realized your annual carrying cost is $500 to $800 higher than every online calculator told you.
The marion ma property tax rate 2026 is $10.19 per $1,000 of assessed value (Town of Marion Assessor’s Office, FY2026). On a $750,000 home, the base tax bill comes to $7,642.50 per year. But Marion sits within the Sippican Water District, which levies a separate fire-district tax on top of the town rate. Add that charge (roughly $0.70 per $1,000, or about $525 on a $750K assessed value), and your real annual property tax obligation lands closer to $8,168. That number doesn’t show up on Zillow, Redfin, or most tax-estimator tools. If you’re budgeting for a Marion purchase in 2026, you need this figure, not the headline rate.
Key Takeaways
- Marion’s FY2026 residential tax rate is $10.19 per $1,000 of assessed value (Town of Marion Assessor)
- A $750K home generates a base tax bill of $7,643, plus ~$525 in Sippican Water District charges
- Marion’s effective rate beats Dartmouth’s but runs higher than Mattapoisett’s
- Assessed values in Marion track within 5% of sale prices, so new buyers can’t expect assessment relief
How is the marion ma property tax rate 2026 calculated?
Marion’s residential tax rate for FY2026 is $10.19 per $1,000 of assessed value, set by the Board of Assessors and approved at the annual Town Meeting (Town of Marion Assessor’s Office, FY2026). Massachusetts is a 100% valuation state, meaning the town assesses your home at full fair market value. There’s no fractional assessment ratio like you’d see in Connecticut or New York.
Here’s the math on a $750,000 home:
- Assessed value: $750,000
- Tax rate: $10.19 per $1,000
- Annual tax bill: $750 × $10.19 = $7,642.50
Simple enough. But this number is incomplete for any home inside Marion’s village center or connected to town water, which brings us to the charge that trips up almost every buyer I work with.
Over 23 years and 250+ closings across the Tri-Town area, I’ve watched buyers budget using only the headline rate. The Sippican Water District surcharge consistently blindsides people at the closing table, adding $400 to $800 annually depending on the assessed value of the property.
What is the Sippican Water District charge, and why does it raise your real tax bill?
The Sippican Water District levies a separate fire-district tax of approximately $0.70 per $1,000 of assessed value on properties within its boundaries (Sippican Water District Annual Report, 2025). On a $750,000 home, that’s roughly $525 per year on top of your town tax bill.
This charge funds fire protection, hydrant maintenance, and water infrastructure across the district, which covers most of Marion’s residential core, including Front Street, Spring Street, and the neighborhoods around Silvershell Beach. If you’re buying on Point Road or in the village proper, you’re almost certainly in the district.
Why doesn’t this show up in online tax calculators? Because Zillow and Redfin pull data from the Massachusetts Department of Revenue’s tax rate database, which reports only the town rate. The water-district surcharge is a separate line item on your actual tax bill from the Town Collector’s office. It’s real money, and it hits quarterly.
Your actual annual cost on a $750K Marion home: approximately $8,168.
That’s $681 per month in property taxes alone, before homeowner’s insurance.
“Buyers relocating from out of state see Marion’s rate and think it’s moderate for Massachusetts, but they never see the Sippican charge until I walk them through the real numbers,” says Christine Medeiros.
The gap between the advertised rate and the effective rate (including the water-district levy) is roughly 6.9%. On a $750K home, that’s the difference between budgeting $637/month and $681/month in taxes. Over a 30-year mortgage, that “hidden” $44/month adds up to nearly $15,840.
How does Marion compare to property taxes in Mattapoisett, Rochester, and Dartmouth?
Marion’s combined effective rate (town plus Sippican Water District) sits in the middle of the Tri-Town pack. Here’s a side-by-side comparison on a $750,000 home using FY2026 residential rates (Massachusetts Department of Revenue Division of Local Services, FY2026):
| Town | FY2026 residential rate (per $1,000) | Annual tax on $750K | Water district add-on | Effective annual total |
|---|---|---|---|---|
| Marion | $10.19 | $7,643 | ~$525 (Sippican) | ~$8,168 |
| Mattapoisett | $9.82 | $7,365 | None (town water included) | ~$7,365 |
| Rochester | $11.45 | $8,588 | None (well/septic town) | ~$8,588 |
| Dartmouth | $12.37 | $9,278 | None | ~$9,278 |
Rochester’s rate is higher on paper, but Rochester homes are assessed lower on average because the housing stock skews toward larger-lot rural properties rather than Marion’s compact waterfront lots. A $750K home in Rochester likely sits on 3+ acres with well and septic, so you’re trading the water-district charge for septic pumping costs (~$400 every 2-3 years).
Dartmouth is the most expensive of the four. A buyer choosing between Padanaram Village in Dartmouth and Marion’s harbor area would save roughly $1,110 per year in taxes on the same $750K assessed value by choosing Marion.
Do Marion’s assessed values match sale prices?
Yes, and that matters more than you think. Marion’s assessment-to-sale ratio sits at approximately 95% to 100% for recent sales (Town of Marion Assessor’s Office, FY2026). Massachusetts law requires municipalities to reassess property values to reflect market conditions, and Marion’s assessors have been aggressive about keeping pace with the 11% price jumps the town saw in recent cycles.
In several Marion closings I’ve handled between 2024 and 2026, the assessed value lagged the sale price by only 2-4% in the first year. By the second year, the assessment caught up entirely. Buyers hoping for a gap between their purchase price and their assessment (and therefore a lower initial tax bill) should budget based on the full $750,000.
Some towns in Massachusetts have assessments that lag 10-15% behind market values, giving new buyers a temporary break. Marion is not one of those towns. If you pay $750K, expect your assessment to reflect $750K within one fiscal year.

What about the residential exemption and other tax relief?
Marion does not currently offer a residential exemption (the optional program some Massachusetts cities use to shift tax burden from owner-occupants to commercial properties and investors). Boston uses one. Marion doesn’t. The town’s tax base is almost entirely residential, so a residential exemption would simply redistribute burden among homeowners without meaningful savings.
However, Marion does offer:
- Clause 41C elderly exemption: homeowners 65+ with qualifying income and assets can receive a reduction of up to $1,000 (Massachusetts General Laws Ch. 59 §5, 2026)
- Clause 22 veterans’ exemption: qualifying veterans receive $400 to $1,500 off their annual bill
- CPA surcharge: Marion assesses a 1.5% Community Preservation Act surcharge on top of the base tax (after a $100,000 residential exemption from the CPA calculation)
On a $750K home, the CPA surcharge applies to $650,000 of assessed value. At the $10.19 rate, that’s about $99 annually. Small, but it’s another line item.
How does the new development on the Weweantic River affect future tax rates?
Construction began in early 2026 on a luxury housing development overlooking the Weweantic River (Sippican Week, April 2, 2026). New residential construction adds to Marion’s total assessed value, which can stabilize or slightly reduce the tax rate if the town’s spending stays flat.
But Marion is also discussing a potential new housing project (Sippican Week, April 7, 2026), which could increase both the tax levy (through infrastructure demands) and the assessed base. The net effect on rates depends on whether new assessed value outpaces new spending.
For buyers closing in 2026, the current $10.19 rate is your planning number. Historically, Marion’s rate has fluctuated between $9.50 and $10.50 over the past decade. Budget for modest annual increases of 2-3%, which is consistent with the statewide trend for South Coast MA property taxes.
If you’re evaluating your credit and financing for a $750K purchase, add $681/month to your PITI calculation, not the $637 that basic calculators spit out.
Frequently asked questions
What is the exact marion ma property tax rate for 2026?
The FY2026 Marion residential tax rate is $10.19 per $1,000 of assessed value (Town of Marion Assessor’s Office, FY2026). Properties inside the Sippican Water District pay an additional ~$0.70 per $1,000 fire-district tax. Combined, the effective rate on a $750K home is approximately $10.89 per $1,000, yielding an annual bill of roughly $8,168.
Is the Sippican Water District tax included in online property tax estimates?
No. Zillow, Redfin, and most online tax calculators pull only the town rate from the Massachusetts Department of Revenue (Mass DOR DLS, FY2026). The Sippican Water District charge (~$525/year on a $750K home) appears only on the actual quarterly bill from Marion’s Tax Collector. Always ask for the real bill before budgeting.
How do Marion massachusetts property taxes compare to other Tri-Town communities?
Marion’s effective rate (including Sippican) is higher than Mattapoisett (~$7,365/year on $750K) but lower than Rochester (~$8,588) and significantly lower than Dartmouth (~$9,278). Mattapoisett folds water costs into its town rate, so its headline number is what you actually pay (Mass DOR DLS, FY2026).
Can I appeal my Marion property tax assessment?
Yes. You can file an abatement application with the Marion Board of Assessors within 30 days of your actual tax bill (not the preliminary bill). Success requires comparable-sale evidence showing the assessment exceeds fair market value. Given Marion’s tight assessment-to-sale ratio, successful abatements are uncommon unless the property has condition issues the assessor missed.
Does Marion offer a first-time buyer property tax break?
Marion does not offer a first-time buyer exemption. Massachusetts provides the MassHousing first-time buyer programs with reduced mortgage insurance and down-payment assistance, but no municipality-level property tax reduction specifically for first-time buyers exists in the Tri-Town area.
Your real number, and what to do with it
The number you came here for: a $750,000 home in Marion costs approximately $8,168 per year in property taxes when you include the Sippican Water District charge. That’s $681 per month built into your mortgage escrow.
Budget with that figure. Share it with your lender when they calculate PITI. And if you’re comparing Marion to other South Coast towns, compare apples to apples by including all district charges, not just the headline rate.
Marion’s tax position is genuinely competitive when you weigh what you get: Sippican School, walkability to the harbor, the Old Rochester Regional school system, and a housing stock that holds value year over year. The taxes are real, but so is the return.
