Tax Implications of Battery Storage Leases for Illinois Landowners

Disclaimer: This article provides general information only. Consult a qualified tax advisor for guidance specific to your situation.

When you lease land for battery energy storage, the lease payments are taxable income. But the tax treatment is generally straightforward, and for most Illinois landowners, the net financial benefit is substantial even after taxes.

Income tax treatment

Battery storage lease payments are generally classified as rental income for federal and Illinois state income tax purposes. This means:

• Payments are reported on Schedule E (Supplemental Income) of your federal return
• You can deduct related expenses (legal fees, accounting, property maintenance on the leased area)
• The income is not subject to self-employment tax — it's passive rental income
• Illinois state income tax applies at the flat rate of 4.95%

Property tax considerations

In Illinois, agricultural land is assessed at a preferential farmland assessment rate that's significantly lower than residential or commercial rates. A common concern is whether a battery storage installation would trigger reassessment.

The answer varies by county, but generally:

• The small footprint (0.2-2 acres) means only a tiny portion of your property could potentially be reassessed
• Many counties classify utility-scale battery installations similarly to other agricultural utility infrastructure
• The remainder of your property retains its farmland assessment
• Even if the leased portion is reassessed at a higher rate, the lease income far exceeds any property tax increase

Depreciation and the developer

The battery equipment itself is owned by the developer, not the landowner. The developer claims depreciation and investment tax credits on the equipment. As the landowner, you don't need to worry about depreciating the installation — you simply report the lease income.

Estate planning considerations

A long-term battery storage lease (20-25 years) becomes part of your property's value for estate planning purposes. The predictable, escalating income stream can actually make estate planning easier by providing a clear cash flow projection. Consult with your estate attorney about how a lease fits into your specific plan.

The bottom line

After federal and state income taxes, a $40,000/year battery lease (5 MW project) nets roughly $28,000-$34,000/year depending on your tax bracket. That's still 60-80x what the same half-acre would earn in farm rent.
