Looking to upgrade your home’s windows while maximizing your savings in 2025 and beyond? Maryland homeowners have access to numerous tax credits and rebates that can significantly reduce the cost of energy-efficient window installations—potentially saving thousands on qualifying projects. This comprehensive guide walks you through every available federal and state incentive, eligibility requirements, and how to claim them for your Mid-Atlantic home improvement project.
Whether you’re replacing drafty windows in Baltimore, upgrading your Annapolis home’s energy efficiency, or preparing for Maryland’s extreme weather in Prince George’s County, understanding these financial incentives makes premium ENERGY STAR® certified windows more affordable than ever. The combination of federal tax credits, state programs, and utility rebates can cover up to 30-40% of your total window replacement investment.
Federal Tax Credits Under the Inflation Reduction Act
The federal government offers substantial incentives for energy-efficient home improvements through the Inflation Reduction Act. In 2024 and 2025, homeowners can claim up to 30% of the total cost of qualifying window installations, with a maximum annual credit of $600 specifically for windows and skylights combined. This represents a significant increase from the previous $200 lifetime limit that existed before 2023.
Key Federal Tax Credit Details:
- Credit Amount: 30% of product and installation costs, up to $600 maximum per year
- Timeline: Available through December 31, 2032
- Annual vs. Lifetime: No lifetime cap—you can claim $600 each year through 2032
- Scope: Applies to your primary residence only (not rental properties or second homes)
- Claiming Process: File IRS Form 5695 with your annual tax return
To qualify for these credits, your window installation must meet specific energy efficiency requirements. Starting January 1, 2025, windows must earn the ENERGY STAR Most Efficient certification to qualify. This generally means triple-pane windows with advanced Low-E coatings and insulated frames. For installations completed in 2024, ENERGY STAR certification (not necessarily Most Efficient) was sufficient.
Important 2025 Change: Beginning with the 2025 tax year, you must include the window’s Product Identification Number (PIN) on your tax return. Thompson Creek provides this documentation for all qualifying window installations.
Maryland State-Level Incentives
Maryland residents enjoy additional state-level incentives that can be combined with federal tax credits for even greater savings. The Maryland Energy Administration (MEA) offers several programs designed specifically for homeowners investing in energy efficiency:
Maryland Residential Clean Energy Grant Program While primarily focused on solar and geothermal systems, this program recognizes that energy-efficient windows are often a prerequisite for maximizing renewable energy performance. Grants up to $1,000 may be available for whole-home energy assessments that include window efficiency evaluations.
EmPOWER Maryland Utility Rebates Maryland’s major utilities offer rebates through the EmPOWER Maryland program:
- BGE (Baltimore Gas & Electric): Up to $250 in rebates for qualifying ENERGY STAR windows as part of comprehensive home energy upgrades
- Pepco: Rebates available through Quick Home Energy Check-up program
- Delmarva Power: Energy efficiency incentives for window replacements combined with other upgrades
- Southern Maryland Electric Cooperative (SMECO): Home energy assessment rebates that identify window upgrade needs
Maryland Home Efficiency Rebates (HERO Program) Maryland is implementing two major rebate programs funded by the Inflation Reduction Act, expected to launch in 2025-2026:
- HERO (Home Efficiency Rebates): Up to $8,000 in rebates for energy efficiency improvements that achieve 20-35% whole-home energy savings
- HEAR (High-Efficiency Electric Home Rebate): Up to $14,000 for qualifying electrification and efficiency projects for low-to-moderate income households
While these programs focus primarily on HVAC and insulation, energy-efficient window replacements often qualify as part of comprehensive whole-home efficiency packages. Check with the Maryland Energy Administration for the latest program status and availability.
Energy Efficiency Requirements for Tax Credits
To ensure your window installation qualifies for these incentives, your windows must meet strict efficiency standards that vary based on Maryland’s climate zone and the tax year of installation:
For 2024 Installations (Standard ENERGY STAR®):
- U-Factor: ≤ 0.27 (measures heat transfer—lower is better)
- Solar Heat Gain Coefficient (SHGC): ≤ 0.25 (measures solar heat blocking)
- Air Leakage: ≤ 0.3 cfm/ft²
For 2025+ Installations (ENERGY STAR Most Efficient):
- Triple-pane construction required in most cases
- U-Factor: ≤ 0.20 (20% better insulation than 2024 standards)
- SHGC: Varies by exposure but typically ≤ 0.23
- Advanced Low-E coatings on multiple surfaces
- Insulated vinyl or fiberglass frames with foam-filled cavities
- Warm-edge spacer systems between panes
These requirements are specifically designed for Maryland’s Mid-Atlantic climate, which experiences hot, humid summers and cold winters—making both heating and cooling efficiency critical. Thompson Creek’s custom-manufactured windows exceed these standards, with many models achieving U-Factors as low as 0.17.

How to Claim Your Window Tax Credits
Step 1: Verify Window Eligibility Before Purchase Confirm your selected windows meet current ENERGY STAR requirements for the year of installation. Thompson Creek provides this verification during your free consultation.
Step 2: Keep All Documentation Save these essential documents for your tax filing:
- Itemized invoice showing product costs and installation labor separately
- Manufacturer’s Certification Statement (provided by Thompson Creek)
- NFRC labels from each window showing energy performance ratings
- ENERGY STAR certification documentation
- Product Identification Numbers (PIN) for 2025+ installations
- Before/after photos documenting the installation
Step 3: Complete IRS Form 5695 File Form 5695 “Residential Energy Credits” with your federal tax return for the year the windows were installed (not purchased). The form has two parts:
- Part I: Residential Clean Energy Credit (not applicable for windows)
- Part II: Energy Efficient Home Improvement Credit (windows go here)
Step 4: Transfer Total to Form 1040 The calculated credit from Form 5695 transfers to Schedule 3 (Form 1040), Line 5, which then flows to your main Form 1040 tax return.
Step 5: Apply for State and Utility Rebates Maryland state programs and utility rebates require separate applications, typically within 60-90 days of installation. Thompson Creek can assist with compiling required documentation.
