Switching to solar energy is a smart move, especially when you know how to save money on the upfront costs. One of the best ways to do that is by taking advantage of the solar tax credit details available to you. If you’re an Illinois homeowner, this guide will walk you through everything you need to know about the federal solar tax credit and how it can make your solar installation more affordable.
What Is the Solar Tax Credit and How Does It Work?
The solar tax credit is a government incentive designed to encourage homeowners to invest in solar energy. It allows you to deduct a percentage of your solar installation costs from your federal taxes. This means you pay less in taxes, which helps offset the initial expense of going solar.
Here’s how it works in simple terms:
You install a solar energy system on your home.
You pay for the installation, including equipment and labor.
When you file your federal tax return, you claim a credit equal to a percentage of your total solar costs.
This credit directly reduces the amount of tax you owe.
For example, if your solar system costs $20,000 and the credit is 30%, you get a $6,000 credit on your taxes. That’s a big saving!
Solar Tax Credit Details: What You Need to Know
Understanding the specifics of the solar tax credit can help you plan your solar project better. Here are the key details:
Credit Percentage: The current credit is 30% of the total cost of your solar system.
Eligible Costs: This includes solar panels, inverters, wiring, and installation labor.
Home Eligibility: The system must be installed on your primary or secondary residence in the U.S.
No Cap: There’s no maximum limit on the credit amount.
Carryover: If your credit is more than your tax liability, you can carry the unused amount forward to future years.
Keep in mind, the credit is scheduled to decrease in the coming years, so acting sooner rather than later can maximize your savings.

How Illinois Homeowners Can Maximize Their Savings
Illinois offers additional incentives that can stack with the federal solar tax credit, making solar even more affordable. Here’s how you can maximize your savings:
Combine Incentives: Look for state and local rebates or grants that reduce your upfront costs.
Use Solar Renewable Energy Credits (SRECs): Illinois has a program where you can earn credits for the energy your system produces and sell them.
Work with Local Experts: Solar Professionals Of Illinois can help you navigate all available incentives and ensure you get the best deal.
Consider Financing Options: Some loans and leases are designed to work with tax credits, making solar accessible without a large upfront payment.
By stacking these benefits, you can significantly lower your net cost and enjoy clean energy sooner.
What Happens When You File Your Taxes?
Claiming the solar tax credit is straightforward but requires some attention to detail. Here’s what you need to do:
Gather Documentation: Keep your receipts and contracts related to your solar installation.
Use IRS Form 5695: This form is specifically for residential energy credits.
Calculate Your Credit: Enter your total solar costs and calculate 30% of that amount.
Apply the Credit: Transfer the credit amount to your Form 1040 to reduce your tax bill.
If you use a tax professional, they can handle this for you. If you file yourself, tax software usually includes prompts for energy credits.

Why Acting Now Makes Sense for Illinois Homeowners
The solar tax credit is a limited-time offer. It’s currently set at 30%, but it will drop in the next few years. Here’s the timeline you should keep in mind:
2024-2025: 30% credit available.
2026: Credit drops to 26%.
2027: Credit drops to 22%.
After 2027: Residential credit expires unless renewed by Congress.
Waiting means missing out on significant savings. Plus, solar technology prices continue to drop, and Illinois offers more local incentives, so the time to act is now.
