If you are pricing impact windows in Florida in 2026, you may still see websites, advertisements, or older articles saying that energy-efficient windows qualify for a 30% federal tax credit up to $600.
That information is outdated for a window project placed in service in 2026.
The IRS currently states that the federal Energy Efficient Home Improvement Credit cannot be claimed for property placed in service after December 31, 2025. That means a new impact-window installation completed in 2026 does not qualify for the former federal Section 25C window credit.
Florida does, however, have a separate home-hardening sales-tax refund for certain qualifying impact-resistant windows, doors, and garage doors purchased during the state’s current program period.
Those are two different tax mechanisms with different rules.
This guide explains the distinction so Florida homeowners can budget a project using current information instead of an expired federal incentive.
Important: This article is general educational information, not tax, legal, accounting, or financial advice. Tax rules can change, and individual eligibility depends on facts specific to the taxpayer, property, product, purchase date, installation date, and program requirements. Confirm tax questions with the IRS, Florida Department of Revenue, and a qualified tax professional.
Quick answer: is there a federal tax credit for impact windows in 2026?
No federal Energy Efficient Home Improvement Credit is available for windows placed in service in 2026.
The IRS states that the credit applies to qualifying property placed in service after January 1, 2023 and before January 1, 2026. Current IRS Form 5695 instructions also state that taxpayers cannot claim the Energy Efficient Home Improvement Credit for expenditures or property placed in service after December 31, 2025.
For Florida homeowners planning a 2026 impact-window project, that means:
- The old federal window credit should not be included as a guaranteed project offset.
- A 2026 installation does not become eligible merely because the impact windows are energy efficient or ENERGY STAR rated.
- A salesperson should not represent the expired federal credit as a current 2026 incentive.
- Florida’s separate home-hardening sales-tax refund should not be confused with the former federal income-tax credit.
If an estimate, article, or advertisement still promises a federal window tax credit for a 2026 installation, verify the claim directly against the current IRS guidance before relying on it.
What was the old Section 25C window credit?
Before 2026, the federal Energy Efficient Home Improvement Credit under Section 25C could apply to certain qualifying home improvements.
For qualifying exterior windows and skylights placed in service during the eligible period, the IRS described a credit equal to 30% of qualified expenses, subject to a $600 annual limit for exterior windows and skylights.
The window requirements were not based on hurricane impact resistance alone. A window had to satisfy the applicable federal energy-efficiency requirements for that credit.
That distinction still matters when reading older content:
Impact resistance and energy-credit eligibility were never the same thing.
A product could be impact rated without qualifying for the federal energy credit, and an energy-efficient window could satisfy energy criteria without being suitable as an impact-protection system for a specific Florida opening.
For a deeper explanation of U-factor, SHGC, Low-E coatings, and energy ratings, see our guide to impact-window energy efficiency in Florida.
Why are some 2026 websites still showing a $600 federal credit?
Because the federal rules changed.
Older articles, sales pages, calculators, and marketing materials may still reflect the previous Section 25C schedule. Some pages may have been written when the credit was expected to continue for several more years.
Current IRS guidance supersedes those older marketing claims for 2026 installations.
As of September 5, 2026, the IRS Energy Efficient Home Improvement Credit page says qualifying improvements could be claimed through December 31, 2025, and the current Form 5695 instructions explicitly state that the credit is unavailable for property placed in service after that date.
That is why homeowners should check the date of the source, not just the headline.
A current tax-related article should answer at least three questions:
- What tax year is being discussed?
- When must the property have been placed in service?
- Is the source a current IRS page or an older article repeating prior rules?
What if my windows were installed in 2025?
A project placed in service in 2025 falls under different rules from a project placed in service in 2026.
The IRS still publishes 2025 Form 5695 instructions for taxpayers dealing with qualifying 2025 expenditures. Those instructions include the former Energy Efficient Home Improvement Credit rules and the additional qualified-manufacturer identification requirements that applied in 2025.
If your windows were actually placed in service during 2025, do not use this 2026 article to determine whether you qualify. Review the IRS rules for the applicable tax year and discuss your facts with a tax professional.
The key issue is the applicable tax year and the date the qualifying property was placed in service—not simply the date you happen to be filing or researching the credit.
What tax benefit is available for some Florida impact-window projects in 2026?
Florida’s current home-hardening sales-tax refund may provide a separate benefit for qualifying homeowners and qualifying impact-resistant products.
This is not the federal Section 25C income-tax credit.
Under section 212.08(21), Florida Statutes, qualifying home-hardening products purchased for an eligible residential property can generate a refund of Florida sales tax previously paid, up to $500 per eligible residential property.
The current statutory purchase period is:
July 1, 2026 through June 30, 2029.
The Florida Department of Revenue also lists Emergency Rule 12AER26-1, Home Hardening Products Sales Tax Refund, and Form DR-26HH for the program.
For a complete eligibility and application explanation, read our dedicated Florida home-hardening sales-tax refund guide.
Federal credit vs. Florida refund: what is the difference?
| Question | Former federal Section 25C window credit | Current Florida home-hardening refund |
|---|---|---|
| Applies to 2026 window installations? | No | Potentially, if all Florida eligibility rules are met |
| Type of benefit | Federal income-tax credit | Refund of Florida sales tax previously paid |
| Current 2026 status | Ended for property placed in service after Dec. 31, 2025 | Active under current Florida law |
| Product focus | Energy-efficiency qualification | Statutorily defined impact-resistant home-hardening products |
| Maximum discussed here | Formerly $600 annual window/skylight limit | Up to $500 per eligible residential property |
| Primary authority | IRS | Florida Statutes and Florida Department of Revenue |
The important budgeting lesson is simple: do not substitute one program for the other.
A Florida sales-tax refund does not revive an expired federal income-tax credit, and an old federal energy-credit article does not establish eligibility for Florida’s current home-hardening refund.
Who may qualify for Florida’s home-hardening refund?
Florida’s current statute limits the refund to an eligible residential property.
The law currently defines that property as a residential property with a site-built dwelling that:
- Has a Florida homestead exemption under section 196.031, Florida Statutes; and
- Has a just value of $700,000 or less.
The statute also defines qualifying home-hardening products and requires installation on the eligible property.
The refund is not automatically available to every Florida homeowner, every building, or every window marketed with hurricane-related language.
Before counting the refund in your budget, verify:
- Property eligibility
- Homestead status
- Just value
- Product eligibility
- Purchase date
- Installation on the eligible property
- Required receipts and documentation
- Current Florida Department of Revenue application instructions
Are impact windows automatically eligible for the Florida refund?
No.
The Florida statute defines an impact-resistant window using specific impact-resistance and wind-pressure standards. A product must meet the current statutory definition rather than merely being marketed as “storm rated,” “hurricane glass,” or “strong glass.”
This is another reason to request the exact product documentation before ordering.
For a Florida impact-window proposal, useful documentation can include:
- Manufacturer and product series
- Florida Product Approval number, when applicable
- Miami-Dade Notice of Acceptance when applicable
- Impact designation
- Approved sizes and configurations
- Design-pressure information
- Installation instructions
- NFRC or ENERGY STAR information when energy performance is being compared
Our guide to Florida Product Approval explains how to review those documents without assuming that a brand name alone proves suitability for a specific opening.
Do you receive the Florida refund at the point of sale?
The current statute describes the benefit as a refund of previously paid taxes.
That means homeowners should not assume the purchase will simply ring up tax-free because the product is impact rated.
The owner must submit the required refund application and supporting documentation to the Florida Department of Revenue, and the department determines whether the application satisfies the program requirements.
The statute currently allows refund applications to be submitted between July 1, 2026 and September 30, 2029.
Keep the required documentation rather than assuming the contractor, manufacturer, or retailer can reconstruct it later.
What documents should you keep for a 2026 project?
Even when a tax benefit is not the primary reason for replacing windows, good project records are valuable.
For a 2026 impact-window project, consider retaining:
- Signed contract and change orders
- Itemized invoices
- Proof of payment
- Sales-tax receipts
- Manufacturer and series information
- Product approval documentation
- ENERGY STAR or NFRC documentation when relevant
- Permit records
- Inspection and closeout records
- Warranty documents
- Photos of permanent product labels or markings when accessible
- Florida Department of Revenue forms and correspondence if applying for the state refund
Do not rely on a verbal statement that a product “should qualify.” Ask for documentation tied to the exact product and project.
Does financing change whether the federal credit exists?
No.
Financing a 2026 window project does not restore the expired federal Section 25C window credit.
Financing and tax eligibility are separate issues.
If you are comparing ways to pay for a project, review the actual financing terms, APR, fees, repayment period, lien implications when applicable, and total cost instead of subtracting an expired federal credit from the project price.
Our Florida impact-window financing guide explains PACE and other financing considerations using current 2026 rules.
What about insurance discounts?
Insurance-related wind-mitigation credits are also separate from tax credits and sales-tax refunds.
Impact windows may contribute to opening-protection classifications used in Florida wind-mitigation rating systems, but the effect on a specific homeowner’s premium depends on the property, insurer, inspection, documentation, and policy rating factors.
Do not convert a possible insurance credit into a guaranteed percentage savings claim.
See our guide to impact windows and Florida homeowners insurance for a more detailed explanation of current wind-mitigation documentation and insurance caveats.
Can you combine Florida’s refund with financing or other programs?
Do not assume programs automatically “stack.”
A financing method, insurance credit, grant, rebate, sales-tax refund, or other incentive can have its own eligibility rules and documentation requirements.
The existence of one benefit does not prove eligibility for another.
Before signing a contract based on a projected “net price,” ask the person making the calculation to identify:
- The exact program name
- The government agency or organization administering it
- Current eligibility rules
- Current application deadline
- Whether approval is guaranteed or conditional
- Whether the benefit is a tax credit, deduction, refund, rebate, grant, financing product, or insurance credit
- Whether the amount is fixed, capped, estimated, or property-specific
If those details are missing, treat the projected savings as unverified until you confirm them with the primary source.
What should a 2026 impact-window estimate say about tax incentives?
A contractor does not need to act as your tax advisor.
A responsible estimate should avoid presenting an expired or conditional incentive as guaranteed cash back.
If tax or incentive information appears in a proposal, ask whether it clearly identifies:
- The program
- The administering agency
- The eligibility conditions
- The maximum benefit
- The effective dates
- Whether the homeowner must apply separately
- Whether the contractor is making a tax determination or simply providing general program information
For 2026, a proposal should not subtract a federal Section 25C window credit from the price of a new installation as though the credit still applies.
A practical 2026 budgeting example
Suppose you are comparing an impact-window proposal this year.
Instead of starting with:
Project price minus $600 federal tax credit
use a more defensible process:
- Start with the actual project price.
- Confirm the exact product and scope.
- Verify permitting and installation requirements.
- Review financing separately, if needed.
- Determine whether your property and products may qualify for Florida’s current home-hardening refund.
- Treat any insurance effect as property- and policy-specific until confirmed.
- Do not subtract incentives that have not been verified.
That produces a more realistic budget and reduces the risk of choosing a contractor based on a benefit you cannot actually claim.
Frequently asked questions
Is there a $600 federal tax credit for impact windows in 2026?
No. The IRS currently states that the Energy Efficient Home Improvement Credit cannot be claimed for property placed in service after December 31, 2025. The former window/skylight credit limit does not apply to a new 2026 installation.
What if a contractor says my 2026 impact windows qualify for the federal energy credit?
Ask for the current IRS authority supporting that statement. Current IRS guidance says the Energy Efficient Home Improvement Credit ended for property placed in service after December 31, 2025.
Can I still claim a federal credit for windows installed in 2025?
Potentially, depending on the 2025 rules and your specific facts. Review the IRS instructions applicable to 2025 and consult a qualified tax professional. A 2025 project should not be evaluated using the rules for a 2026 installation.
Does Florida have a tax benefit for impact windows in 2026?
Yes, Florida currently has a home-hardening sales-tax refund for qualifying impact-resistant windows, doors, and garage doors used on eligible residential properties. The refund is capped at up to $500 per eligible property and has specific property, product, purchase-period, installation, and application requirements.
Is Florida’s home-hardening benefit a federal income-tax credit?
No. It is a Florida sales-tax refund program. It is separate from the expired federal Section 25C Energy Efficient Home Improvement Credit.
Are all impact windows eligible for Florida’s refund?
No. The product must satisfy the statutory definition and the property and owner must meet the program requirements. Verify the exact product documentation and current Florida Department of Revenue instructions.
Does financing make a 2026 project eligible for the old federal credit?
No. How a project is financed does not restore a federal credit that has ended for 2026 installations.
Should I choose impact windows only because of a tax incentive?
No. Tax benefits can change and may have narrow eligibility rules. Evaluate the actual product approval, design pressure, installation method, energy performance, warranty, project scope, financing terms, and property needs first.

Tax and incentive rules can change. Verify current information with primary sources:
- IRS — Energy Efficient Home Improvement Credit

The bottom line
For impact windows placed in service in 2026, the former federal Section 25C window tax credit is no longer available. Current IRS guidance says the Energy Efficient Home Improvement Credit ended for property placed in service after December 31, 2025.
Florida homeowners may instead have access to the state’s separate home-hardening sales-tax refund when the property, product, purchase, installation, and application satisfy current Florida requirements.
That distinction matters because some current websites still repeat the expired $600 federal window-credit language.
Before relying on any incentive, identify the exact program, verify it with the government agency administering it, and keep the documentation tied to your specific project.
