Is a New Roof Tax Deductible in Massachusetts?

Short answer: no, not on your federal return and not on your Massachusetts return, when the roof is a standard tear-off-and-reroof on your primary residence. The pages still ranking for "roof tax deduction" fall into two camps that are both wrong for 2026 work. The first camp says "a new roof is a home improvement deduction" and sends you to a Schedule A line that does not exist. The second camp points at IRC Section 25C (the Energy Efficient Home Improvement Credit) or Section 25D (the Residential Clean Energy Credit) as if they still cover roofs for a 2026 install. Section 25C never covered a standard asphalt or metal roof after the 2022 overhaul of that credit, and both 25C and 25D were terminated for property placed in service after December 31, 2025 by P.L. 119-21 (the 2025 "One Big Beautiful Bill Act").

So what, if anything, does a Massachusetts homeowner get back on taxes? Five narrow things, each with a specific rule: a cost-basis adjustment at sale (which almost never saves money because of the $500,000 / $250,000 Section 121 exclusion), a home-office pro-rata depreciation at 39 years, a residential-rental depreciation at 27.5 years, interest on a home-equity loan that paid for the roof if the balance stays under the acquisition-debt cap, and a casualty-loss deduction that only applies after a federally declared disaster. Here is the full picture in one screen.

Everything below unpacks the rows that matter most for a Massachusetts homeowner looking at a $20,000 to $35,000 roof bill.

Why a standard re-roof is not deductible for MA primary residences

A new roof on the house you live in is a capital expenditure, not a current-year deductible expense. The IRS puts "new roof" in Publication 523's list of "Examples of Improvements That Increase Basis," under the Exterior category. That is a bookkeeping category, not a credit or a deduction. It means you add the money you spent on the roof to the cost basis of your home. The basis matters only when you sell. If you never sell, or if your gain at sale falls under the Section 121 exclusion, the basis adjustment never saves you a dollar.

Massachusetts does not have a parallel state deduction for home improvements on a primary residence. MA personal income tax starts from federal gross income and applies state-specific adjustments. For principal residences, MA explicitly conforms to the federal Section 121 exclusion, by the state's own tax expenditure listing: "Massachusetts conforms to the Internal Revenue Code (the 'Code') § 121 exclusion from gross income for up to $250,000 of capital gain (or $500,000 if filing jointly) on the sale of a principal residence," cited to M.G.L. c. 62, §§ 1(c), 1(d), and § 2(a) (MA FY26 Tax Expenditure Budget 1.021). There is no Schedule SC-style credit for roofs. The MA Title 5 septic credit exists for septic systems and only septic systems. The lead-paint removal credit exists for lead abatement only. Nothing in MA law carves out a roof.

Cost basis and the Section 121 exclusion: where "basis" rarely matters

The IRS treats a new roof as a basis-increasing improvement because it either prolongs the home's useful life or adapts it to a new use. Pub 523 names it: Exterior improvements that count include "New roof," "Siding," "Storm windows and doors," among others. Keep the final invoice, the paid-in-full statement, the HIC contract and the permit receipt in a file for the life of the house. Twenty-two years later when you sell, your accountant will add that $28,000 to the price you paid for the home when calculating gain.

The catch is the Section 121 exclusion. On the sale of a principal residence you lived in for at least 2 of the last 5 years, the first $250,000 of gain is excluded if you file single and the first $500,000 is excluded if you file jointly. Massachusetts conforms to this exclusion dollar for dollar. For a typical MA house that was bought for $420,000 and sells for $780,000, the gain is $360,000. Married joint, the exclusion is $500,000, so the taxable gain is $0 whether or not the roof is in the basis. The roof receipt earns you nothing at the register.

Where cost basis does start to matter: when the gain climbs above the exclusion. In Boston, Cambridge, Somerville, Brookline, Newton, Needham, Lexington, Weston and Wellesley, a long-tenure sale on an owner that bought in the 1990s can easily clear the $500K joint exclusion. On that overage, Massachusetts taxes long-term capital gains at 5% (and a 4% "millionaire's surtax" on taxable income above a threshold indexed for inflation, $1,107,750 for tax year 2026). Federal long-term capital gains sit at 15% or 20% depending on income. On a $100,000 overage, a $28,000 roof you remembered to add to the basis would knock the MA tax by $1,400 and the federal tax by $4,200 to $5,600. The receipts are worth something, if the sale is big enough.

For most MA sellers under the exclusion, "keep the roof receipts" is file-cabinet housekeeping, not tax strategy.

What 25C and 25D used to do, and why they don't now

Two federal credits sit in the chatter about "roof tax credit." Both are now off the table for a 2026 install.

Section 25C, the Energy Efficient Home Improvement Credit, does not cover standard roofs. Pre-2023, under the earlier name "Nonbusiness Energy Property Credit," 25C used to allow a small credit on ENERGY STAR metal roofs with pigmented coatings and asphalt roofs with cooling granules. The Inflation Reduction Act replaced that version of 25C effective for property placed in service beginning January 1, 2023, and the roof category did not survive the rewrite. The current IRS 25C page lists qualified improvements as doors, windows, skylights, insulation, air sealing, home energy audits, central AC, water heaters, furnaces, boilers, heat pumps, and biomass stoves and boilers. Roofs are not on the list. If a national roofing blog is still writing about an "ENERGY STAR roof credit" in 2026, that blog is citing pre-2023 law.

Section 25D, the Residential Clean Energy Credit, did cover solar roof shingles and tiles until it was terminated. The IRS 25D page states that integrated photovoltaic roofing like solar shingles and solar roof tiles qualify, while "traditional shingles that support solar panels do not." That means a Tesla Solar Roof install got the 30% credit through the end of 2025, but a conventional asphalt roof paired with rack-mounted solar panels never did (the panels get 25D, the roof itself never did).

Both credits were terminated by P.L. 119-21 (the 2025 "One Big Beautiful Bill Act," signed July 4, 2025). The IRS OBBB FAQ states: 25C "will not be allowed for any property placed in service after December 31, 2025," and 25D "will not be allowed for any expenditures made after December 31, 2025." For 25D specifically, FAQ #7 says the "expenditure" is deemed made on the date installation is completed, not the date you paid. A solar-roof shingle project you contracted for in October 2025 but that finished installation in January 2026 gets no credit, even though you wrote the check in 2025.

If you are reading this because you are weighing a solar-roof-shingle install for 2026, the math has to work on its own, without 25D. For a conventional asphalt or metal re-roof: there was no federal credit for your roof in 2023, 2024, or 2025 either, and there is no federal credit in 2026 regardless of 25C/25D expiration.

Home office, rental, and casualty: the three cases where a roof actually moves tax dollars

Three narrow federal paths let a MA homeowner recover roof dollars on a current return.

Home office. If you qualify for the home-office deduction (regular and exclusive use, principal place of business), IRS Publication 587 treats a new roof as an indirect expense that affects the whole home and is depreciated separately from the home's original basis. The pub states that "the costs of improvements made after you begin using your home for business (that affect the business part of your home, such as a new roof) are depreciated separately," and prescribes multiplying the improvement cost by the business-use percentage and depreciating that number over 39 years straight-line. For a home office that occupies 8% of the house and a $28,000 roof, the depreciable amount is $2,240, deducted at $57 per year for 39 years. It is real money, but it is tiny per year.

Rental property. On a rental, the roof is a different animal. IRS Publication 946 requires you to treat the new roof as a separate depreciable asset. It states: "If you completely replace the roof, the new roof is an improvement because it is a restoration of the building. You depreciate the cost of the new roof." For residential rental, the recovery period under MACRS GDS is 27.5 years straight-line. For the same $28,000 roof on a rental, that is about $1,018 per year in depreciation, which flows through to Schedule E on the federal return and the corresponding MA rental-income lines. If you sell the rental, prior depreciation is recaptured as unrecaptured Section 1250 gain, so this benefit comes with a tax at the end.

Casualty loss, federally declared disaster only. IRS Publication 547 is explicit: "For tax years beginning after 2017, if you are an individual, casualty losses of personal-use property are deductible only if the loss is attributable to a federally declared disaster." The Tax Cuts and Jobs Act narrowed casualty losses to federally declared disasters only. For most MA storm damage, nor'easters, strong wind events and even hurricanes that come up the coast, no federal disaster declaration follows, so no casualty deduction follows. When FEMA does declare a MA county a disaster area, the loss is figured as the smaller of the decrease in fair market value or the adjusted basis, minus any insurance reimbursement, minus a $100 per-event floor, minus 10% of adjusted gross income. The last part is the ceiling that bites: a $20,000 uninsured roof loss on a household with $120,000 AGI nets out at $20,000 - $100 - $12,000 = $7,900 deductible. For a storm with no federal declaration, the number is $0.

The practical point: for a MA homeowner, the insurance claim is the thing that reduces out-of-pocket on a storm, not the casualty-loss deduction. See our roof storm-damage insurance claims guide for the carrier side.

Interest on a HELOC that paid for the roof

If you financed the roof with a home-equity loan or HELOC, the interest on that debt can be deductible as home mortgage interest, within limits. IRS Publication 936 says: "Interest on home equity loans and lines of credit are deductible only if the borrowed funds are used to buy, build, or substantially improve the taxpayer's home." A full re-roof is a substantial improvement (not routine maintenance like a tune-up or a repaint). The two caveats to run past your accountant: the loan has to be secured by the home itself, and the combined acquisition debt (your first mortgage plus the HELOC balance used for the roof) has to fit under the TCJA cap. Pub 936 states: "For debt secured after December 15, 2017, the limit is $750,000 ($375,000 if married filing separately)." Older grandfathered mortgages have a different ($1,000,000 / $500,000) cap. Massachusetts does not add its own mortgage interest cap.

If the HELOC paid for the roof plus other costs, keep the roof portion traceable in the loan file. Interest allocation is pro-rata. Our financing a MA roof replacement guide covers which financing path (homeowners insurance claim, HELOC, HELOAN, Mass Save HEAT Loan, contractor financing) matches which situation.

What about Mass Save?

Mass Save is a rebate program, not a tax credit. Rebates and tax deductions do not interact the way most homeowners assume. A Mass Save rebate is not taxable income to you under current IRS guidance (treated as a utility purchase-price reduction, not income), but any rebate you receive does reduce the cost basis of the improvement on which the rebate was paid, per the subsidy-and-rebate rules in IRS Pub 523.

For a roof itself, this is mostly moot. Mass Save sponsors do not run a roof-replacement rebate program. The sponsors (Eversource, National Grid, Unitil, Berkshire Gas) run rebate programs for air sealing, attic insulation, heat pumps, water heaters, and ductless mini-splits, which can be tied to a re-roof when you open the attic plane for the first time in decades. If your town is served by one of the four Mass Save sponsor utilities, the air-seal-and-insulate line on the project can earn a Mass Save rebate. For the 50 Massachusetts cities and towns served by their own municipal light plant, Mass Save's electric rebates do not apply, though if the home takes natural gas from a Mass Save sponsor's gas account (National Grid, Eversource gas, Unitil or Berkshire Gas), the gas-side of Mass Save still does. A few MLP towns run their own weatherization programs, most do not. For the full map see our MLP towns without Mass Save guide.

What to keep in your records

Whether or not any of this saves you money today, the paper trail matters at sale and at audit.

• The signed Home Improvement Contractor (HIC) contract, with the registration number.
• Final invoice marked paid in full, dated.
• The paid building permit receipt from the town building department.
• Any manufacturer registrations tied to the shingle brand, if you want the wind warranty to survive scrutiny (wind warranty guide).
• Insurance claim documents, if the roof was storm-related.
• Any Mass Save rebate paperwork tied to attic air sealing or insulation that rode along with the roof.
• Loan documents for a HELOC or HELOAN that funded the project, so you can trace the interest-deduction allocation.

Keep the file for the life of the house plus three years after you sell. A new roof is a 25-year-plus asset on paper; a well-kept file is the only way the tax code's narrow carve-outs ever work in your favor.

FAQ

Can I deduct my new roof on my 2026 federal return? Not if the house is your primary residence and the roof is standard asphalt or metal. There is no current federal credit or deduction for a conventional re-roof on your personal home. The money gets added to your home's cost basis per Pub 523, which only matters if you sell at a gain above the $250,000 / $500,000 Section 121 exclusion.

Does the IRS Section 25C Energy Efficient Home Improvement Credit cover my new asphalt or metal roof? No. Roofs were removed from 25C in the 2022 overhaul; the current IRS 25C page list of qualified improvements does not include roofs. And 25C itself was terminated for property placed in service after December 31, 2025 by P.L. 119-21.

What about solar roof shingles or Tesla's Solar Roof, do those get a credit? They did under IRC 25D through December 31, 2025 (IRS 25D page). For installations completed after that date, 25D is terminated. The IRS treats the "expenditure" as made on the installation-completion date, not the payment date (OBBB FAQ #7).

Does Massachusetts have its own state tax credit for a new roof? No. MA has state credits for Title 5 septic replacement, lead-paint abatement, and a few other narrow categories, but nothing for roof replacement. MA personal income tax starts from federal gross income and conforms to Section 121's $500K joint / $250K single principal-residence exclusion (MA tax expenditure 1.021).

My rental property needed a new roof. Can I deduct the whole thing this year? No. Per IRS Pub 946, a complete roof replacement on rental property is a capital improvement, not a current-year expense. You depreciate it as a separate asset over the residential-rental MACRS schedule (27.5 years straight-line). The year's deduction is roughly 1/27.5 of the cost. Repairs that keep the roof in ordinary operating condition (patching a flashing leak, replacing a few shingles) are still deductible as current-year expenses on Schedule E.

A hurricane blew half my shingles off. Can I claim a casualty loss? Only if your county was in a federally declared disaster area for that storm. Pub 547 narrowed personal-use casualty losses to federally declared disasters for tax years after 2017. Even then, you subtract insurance reimbursement, the $100 per-event floor, and 10% of AGI, so the net deduction is often small. The insurance claim is what makes you whole on a MA storm roof.

Get quotes

If you are at the budgeting stage of a Massachusetts re-roof, the tax side rarely moves the number more than a few percent, so the real decision is on the quote itself. A good MA roofing quote names the shingle brand and line, the number of squares, the underlayment type, the ice-and-water-shield footprint (780 CMR requires it 24 inches past the warm wall line in our climate zone), the drip edge, the starter strip, the ridge-vent length, the flashing scope, the nail pattern (6-nail wherever Vult is 110 mph or more, which is every town in MA per the wind-warranty guide), the decking replacement allowance, dumpster and disposal, and the warranty terms side by side. A lump-sum "replace your roof" quote with no line items is a comparison problem waiting to happen.
