How to Maximize Solar Tax Incentives in 2025

Introduction

Tax incentives are one of the most compelling reasons to invest in commercial solar in 2025. With the federal Investment Tax Credit (ITC) extended and bonus incentives available through the Inflation Reduction Act (IRA), businesses can significantly reduce the upfront costs of solar installations. However, navigating these incentives requires strategy, timing, and compliance to maximize benefits. Here’s how your business can capitalize on current tax advantages with Surge as your guide.

💰 The Federal Investment Tax Credit (ITC)

The ITC remains the cornerstone of federal solar incentives:

• Currently set at 30% of total system cost for eligible projects

• Available through at least 2032 under the IRA

• Applies to solar installations, battery storage (even standalone), and related equipment

By applying the ITC, a $500,000 solar project could yield $150,000 in direct tax credits.

➕ Bonus Credits and Adders

The IRA introduces several bonus credits that can boost your ITC beyond 30%:

• Domestic Content Bonus: Additional 10% if materials are primarily U.S.-made

• Energy Communities Bonus: Extra 10% for projects in areas with historical fossil fuel industries

• Low-Income Bonus Credit: Up to 20% additional credit for projects serving low-income communities or housing

These adders can stack, potentially increasing the credit to 50% or more under qualifying conditions.

🗂️ Accelerated Depreciation (MACRS)

In addition to the ITC, commercial solar projects can utilize the Modified Accelerated Cost Recovery System (MACRS):

• Allows for accelerated depreciation of the system over 5 years

• Provides additional tax deductions, enhancing cash flow and ROI

• Bonus depreciation allows for 60% of the cost to be depreciated in the first year (as of 2025)

This dual benefit of tax credit plus depreciation can significantly lower your tax liability.

🕒 Timing is Everything

To maximize incentives:

• Begin projects before potential policy changes or phase-downs after 2032

• Ensure documentation for Domestic Content and Energy Community qualifications is precise

• Work with tax professionals early to align the solar project timeline with fiscal planning

Surge ensures all documentation is in order for clients to claim these benefits efficiently.

📋 Eligibility and Compliance Requirements

To claim the maximum tax credits:

• Comply with prevailing wage and apprenticeship requirements for projects over 1 MW

• Use qualified installers and certified equipment

• Properly file IRS Form 3468 to claim the ITC

Failure to meet these conditions can result in reduced credits or penalties.
