How Boston’s Residential Exemption Lowers Your Tax Bill

Buying in Boston and wondering if there’s a way to trim your property tax bill? If you live in the home you own, the city’s residential exemption could lower the taxable value that your bill is based on. That means real savings each year you occupy your home as your primary residence.

In this guide, you’ll learn how the exemption works, who qualifies in Boston, when and how to apply, and how to confirm it on your bill. You’ll also see a simple example so you can estimate potential savings. Let’s dive in.

What the residential exemption is

Boston can reduce the taxable portion of an owner-occupied home’s assessed value through a residential exemption. The authority for this program comes from Massachusetts General Laws, Chapter 59, Section 5C. The policy is designed to shift some of the tax burden from owner-occupied homes to other property types, helping people who live in their homes.

Each municipality chooses whether to adopt the exemption and sets the percentage within state limits. Boston’s Assessing Department sets the adopted percentage and publishes the rules, forms, and deadlines each year. Because these numbers can change annually, always verify current details directly with Boston Assessing before you apply.

Who qualifies in Boston

You generally qualify if the home is your principal, legal residence and it is taxed in the residential class. Single-family homes and condominiums often qualify when owner-occupied. Multi-family rules can vary, so review Boston’s guidance if you own a 2- or 3-family and live in one unit.

Eligibility is tied to ownership and occupancy as of Boston’s assessment or valuation date for that fiscal year. If you bought the property after the date used for that year, you may need to wait until the next fiscal year to receive the benefit.

Key eligibility checklist

• You own the property and it is your primary residence.
• The property is in the residential tax class.
• You met Boston’s ownership and occupancy requirement as of the city’s valuation date for the fiscal year.
• You can document ownership and occupancy if requested.

When to apply and your timeline

Boston sets its own application process and deadline. Some communities apply the exemption automatically after you establish eligibility, while others require an application and possibly reapplication. Always follow Boston’s posted instructions for the current fiscal year.

If you purchased close to the city’s valuation date or near the filing deadline, act quickly. Gather proof of occupancy right after closing and submit your application as soon as the ownership change appears in city records.

New buyers: practical timeline

• Right after closing: Confirm your deed is recorded at the Suffolk County Registry of Deeds so Boston’s records show you as owner.
• Verify the valuation date: Determine whether you were the owner-occupant on that date for the current fiscal year.
• Check Boston’s deadline: Find the current filing window on the Assessing pages.
• Apply early: Submit your application with all required documents and keep proof of submission.

How to apply in Boston

Follow Boston’s current instructions exactly. The steps below reflect common requirements under state law and typical municipal practice.

1. Confirm ownership on record

• Make sure the city shows you as the owner of record. Allow time for the recording to update.

2. Gather proof of owner-occupancy

• Deed or settlement statement
• Driver’s license or state ID with your property address
• A recent utility bill, voter registration, or similar proof tied to the property address

3. Complete Boston’s Residential Exemption application

• Get the form from the Boston Assessing Department or its website.
• Fill out every field and attach the requested documents.

4. Submit by the city’s deadline

• File by mail, in person, or online if offered. Keep copies and proof of receipt.

5. Confirm the outcome

• When tax bills are set, review your bill to confirm the exemption appears. If it does not and you believe you were eligible and filed on time, contact the Assessing Department right away for next steps.

6. If you miss the deadline

• Municipalities generally do not grant the exemption retroactively for a missed year. Plan to file for the next fiscal year and ask Boston Assessing about any limited remedies.

How it appears on your Boston tax bill

Your bill will show the full assessed value, the residential exemption amount, the net taxable value after the exemption, and the tax rate applied per $1,000 of taxable value. The exemption reduces the taxable value used to calculate your tax, not the tax rate itself.

Hypothetical savings example

Example only. Always check Boston’s current adopted percentage and tax rate.

• Assessed value: $700,000
• Residential exemption: 10% of assessed value (hypothetical)
  • Exemption amount: $70,000
• Net taxable value: $700,000 minus $70,000 equals $630,000
• If tax rate is $12.00 per $1,000 (hypothetical)
  • Tax due: $630,000 times $12.00 per $1,000 equals $7,560
• Without the exemption: $700,000 times $12.00 per $1,000 equals $8,400
• Annual savings in this example: $840

Your actual savings will depend on Boston’s adopted exemption percentage, your home’s assessed value, and the tax rate for the fiscal year.

Common pitfalls to avoid

• Waiting too long to file: Missing the filing window can cost you a full year of savings.
• Incomplete documents: Small gaps, like a driver’s license that does not yet show your new address, can delay approval.
• Assuming multi-family rules: If you own a 2- or 3-family, verify Boston’s treatment of owner-occupied multi-family properties.
• Moving out without updating the city: The exemption is for your principal residence. If your occupancy changes, notify the Assessing Department.

Related programs and appeals

You may also qualify for other exemptions based on factors like age, disability, or veteran status. Rules on whether you can combine exemptions vary. Check Boston’s Assessing guidance for details.

If your assessed value seems too high, you can consider an abatement application. The residential exemption does not change your assessed value. It only reduces the taxable portion. Follow Boston’s abatement timeline and procedures if you choose to appeal your assessment.
