# Belmont's FY2026 Property Tax Rate: What It Means for Home Buyers
Key Takeaways
•The quick answer: Belmont's FY2026 residential tax rate is $11.51 per $1,000 of assessed value, per the town's fiscal 2026 figure. Run it like this: assessed value ÷ 1,000 × 11.51 ÷ 12 = your monthly tax escrow — the tax money your lender collects and pays the town.
•The real number: On a $1,500,000 assessed value, the annual tax is $17,265. Spread over twelve payments, that works out to about $1,439 a month.
•The Belmont catch: Your bill is the rate times the taxable value, and Belmont's values are high. A town with a higher rate can still send a smaller bill.
•The bottom line: Use the assessor's assessed value, not your purchase price — then stress-test at your ceiling price before you bid.
Why does Belmont's tax rate matter to buyers?
A tax rate looks like fine print until your lender's escrow estimate arrives. Then it becomes real money every month, for as long as you own the home.
Here's the math you can run at an open house:
Assessed value ÷ 1,000 × $11.51 ÷ 12
That gives your monthly tax escrow — the amount your lender collects with your mortgage payment and sends to the town.
Rates are reset on a yearly cycle. Before you budget, ask the Belmont Board of Assessors whether a newer rate has been approved. If one has, use that number instead of $11.51.
What does the rate cost at real Belmont prices?
Belmont is an expensive market, so the tax line adds up fast. The average home value is $1,446,989, up 1.5% over the year — that's a market figure, and the town taxes its own assessed value, which is usually lower.

Belmont FY2026 Property Tax by Assessed Value

On a $1,500,000 assessed value, the annual tax is $17,265 — about $1,439 a month once your lender divides it across twelve payments. At a $1,232,500 assessed value, the annual tax is $14,186. At $1,600,000, it rises to $18,416. That is before principal, interest, insurance, utilities, or maintenance.

If you're competing for a single-family, you may have one weekend to decide. Pull the assessed value and run the escrow math before the showing, not after.
What are the strongest arguments against worrying about the tax rate?
"Using the purchase price may overstate the bill."
Fair — and often true. The town's assessed value is usually lower than what a buyer just paid, so multiplying the rate by your purchase price will overstate your bill. That's why you start with the assessed value, the number Belmont uses for tax purposes. Pull it from the Belmont Assessors' database before you write an offer. Then run the math again at your ceiling price, so you know the outer edge of what the tax line could cost you.
"Belmont's rate is not that high."
Also fair. But the rate alone doesn't set your bill — the taxable value does, and Belmont's values are high. That's where the money is.
Exemptions can matter too. Some nearby towns cut the taxable value for owner-occupants: Watertown's assessing department reports its FY2026 residential exemption removes $324,715 of value, worth $3,961.52. Ask the Belmont Board of Assessors what relief, if any, applies to you.
"FY2026 is over, so is this number stale?"
Treat $11.51 as a confirmed benchmark, not a promise about the future. Ask the Board of Assessors whether a newer rate has been approved, and budget with whichever figure is current.
What number should you bring to your next Belmont showing?
Before you offer, do four things:
1. Pull the parcel's assessed value from the Assessors' database.
2. Divide by 1,000, then multiply by $11.51.
3. Divide by 12 and share that number with your lender.
4. Run it again at your ceiling price, not just your target price.
Belmont's schools, walkability, and commuter rail access to North Station are big reasons buyers choose this town. Just make sure the tax line fits your real monthly life before you sign. Send me the address you're considering, and we'll walk through the numbers together.
