Calculator Disclaimer

Save Our Stoneham's Tax Impact Calculator is not approved nor endorsed by the Town of Stoneham, the Massachusetts Department of Revenue, nor any other official entity.

Save Our Stoneham is a Ballot Question Committee (Federal EIN# 33-3135282) focused on addressing Stoneham's budget challenges and supporting a Proposition 2½ override to protect vital community services.

Estimates provided by this calculator are based on official FY2025 data and are for informational and comparison purposes only. Actual tax impacts may vary based on final override amounts, assessed property values, baseline increases, and other adjustments to the tax levy.

For official tax information, please contact the Stoneham Assessors Office or Town Administrator's Office.

Calculator Methodology

Our calculator provides transparent, accurate estimates of how the proposed Proposition 2½ override will impact your property taxes based on official FY2025 data. We use official town and state data and clearly disclose all limitations.

The Two Override Questions

Voters will be asked to consider two separate override amounts:

Question 1: $12.5M Override

Tax rate increase: $1.89 per $1,000 of assessed value (based on FY2025 valuations)

Question 2: $9.3M Override

Tax rate increase: $1.40 per $1,000 of assessed value (based on FY2025 valuations)

These rate adjustments are derived using the Massachusetts Department of Revenue's Division of Local Services Tax Impact Calculator methodology applied to official FY2025 data.

What This Calculator Includes

  • Official FY2025 property assessments from Patriot Properties Assessment database (last pulled Saturday, November 1st, 2025)
  • Note: your latest tax bill is the most accurate source for your property assessment. The Patriot Properties data may be out-of-date.
  • Accurate comparison between the two override scenarios based on FY2025 valuations
  • Transparent methodology with disclosed data sources

What This Calculator Does Not Include

  • Estimated FY2026 baseline tax increases
    • The town projects a baseline levy increase of $3,435,043 (source - slide 25), which includes:
      • 2.5% statutory increase: $1,505,113
      • Estimated new growth: $700,000
      • Debt exclusion increase: $1,229,930
    • We do not calculate rate or per-household impacts from this baseline increase because doing so would require data not yet available
  • FY2026 property revaluations
    • New assessments not yet completed
    • Could increase or decrease your individual assessment
    • Changes in total town valuation affect the tax rate
  • Changes to total parcel count
    • New construction affects the tax base
    • Cannot be known until final certification
    • More parcels may mean lower rates: when new homes or developments are added to the tax rolls, the levy burden is shared across more households, which decreases the tax rate for everyone
  • Final certified new growth numbers
    • Town estimates $700,000; actual may differ
    • Certified by MA DOR after fiscal year end
    • New growth may reduce rates: additional property value from new construction is added to the tax base, spreading the levy across a larger valuation and lowering the rate per $1,000

Why We Exclude FY2026 Baseline Estimates

We believe it would be irresponsible to speculate about FY2026 baseline tax rate or per-household impacts without knowing:

  1. Final property assessments - Revaluation could significantly change your individual assessment and the total town valuation

  2. Total parcel count - New construction adds properties to the tax rolls. This spreads the levy burden across more households, which directly lowers the tax rate. The more properties sharing the levy, the less each individual property pays per $1,000 of value.

  3. Certified new growth - The town estimates $700,000 in new growth, but the actual certified amount from MA DOR may differ. New growth lowers tax rates by adding property value to the tax base without requiring a proportional increase in the levy. This additional value gets taxed at the existing rate, and the revenue helps fund services while reducing the rate needed for everyone else.

  4. Total town valuation - Higher property values across town mean lower tax rates. Under Proposition 2½, the levy is capped, so if the total value of all property in town increases, the rate per $1,000 must decrease to stay within the levy limit. The same levy divided by a higher valuation equals a lower rate.

The town's FY2026 budget presentation projects a baseline levy increase of $3,435,043, consisting of:

  • $1,505,113 from the 2.5% statutory increase
  • $700,000 from estimated new growth
  • $1,229,930 from debt exclusion increases (high school debt service)

However, we cannot responsibly calculate what tax rate or per-household impact this levy increase will produce until we know the final assessed valuations, parcel counts, and certified new growth. These factors will determine how the levy is distributed across the tax base.

Our calculator shows ONLY the override impact to provide the most accurate, transparent estimate possible with currently available data.

Important Limitations & Disclaimers

Your actual FY2026 tax bill may differ from this calculation because:

  1. Baseline FY2026 increases are not included

    • Even with no override, taxes will increase
    • The town projects a baseline levy increase of $3,435,043
    • The actual rate and per-household impact depend on factors not yet known
  2. Your individual assessment may change

    • FY2026 revaluation is underway
    • Your home value may increase or decrease relative to the average
    • Market conditions, improvements, and other factors affect assessment
  3. Tax rate automatically adjusts based on total town valuation

    • Under Proposition 2½, the levy limit constrains how much can be collected
    • If total property values increase, rates must decrease
    • If new homes are built, the levy spreads across more properties
    • If new commercial development occurs, it adds value without adding residential burden
  4. This calculator provides estimates for comparison purposes only based on FY2025 data

    • It allows you to compare the impact of the two override scenarios using FY2025 valuations
    • It does NOT predict your exact FY2026 tax bill
    • For official tax information, contact the Assessor's Office

Calculator Source Code

Our calculator is built on open-source principles, ensuring full transparency in how we calculate tax impacts. The current version on this website is specifically tailored to the two ballot questions ($9.3M and $12.5M overrides), providing focused, accurate estimates for these exact scenarios.

The original open-source calculator framework is available on GitHub and demonstrates the broader methodology that can be applied to any override amount. While we've refined the website version for these specific ballot questions, the underlying calculations and approach remain consistent with the transparent methodology documented in the original code:
