Do You Pay Tax on Solar Power Sold to the Grid?

Credits, payments and why the difference matters

This guide is general information, not tax advice. Tax rules differ by person and by year, so the final word belongs to the Canada Revenue Agency and to an accountant who has seen your actual situation.

In many net metering arrangements, extra power sent to the grid is recorded as a credit that reduces later bills. Economically, the owner is using the grid like a bank for their own energy. A cash payment for power, on the other hand, looks like revenue, and revenue raises the question of whether it is business or property income. The wording of the contract and the utility's billing practice matter, so keep both. The principles of Alberta's arrangement are in the net metering explainer and the rules around who can connect in the micro-generation regulation guide.

When is a household in the clear, and when not?

People often assume small household systems never raise a tax question, and for a typical home array that offsets personal use, that is a common outcome. But the answer is not guaranteed. The risk factors tend to be sizing well beyond personal use, a sale of power under a separate contract, or a system that is run as a business. A homeowner with a modest system and standard credits should still confirm, because the tax authority looks at the substance of the arrangement and not at the label on the bill.

When the system is oversized for the household, the question of whether it looks like a business grows. Sizing methods are covered in how many panels a house needs.

Business owners, farms and landlords

If a business owns the system, power sold or credited generally flows into the business's books, and the cost and the income are handled together. A farm that sells surplus under a commercial arrangement, or a landlord whose tenants pay for power, enters different territory than a household. Often the two sides, income and expenses, are tracked together, including depreciation of the system. See the capital cost allowance guide for the expense side and the small business guide for ownership and records.

Leases, power purchase deals and third-party owners

If a company owns the equipment and you pay it for the power or a lease fee, the company reports the revenue and you generally do not earn income from the system. But your payments might raise questions of their own if the property is a rental or has a business use. Read the contract for who owns the equipment, who receives the credits and who claims any available incentive. The financing options guide compares the structures.

What to do before you sign

Ask the utility how credits or payments will appear on your account, and ask the installer or seller for written confirmation of the structure. Then take both documents to an accountant if there is any business, rental or farm element. Keep production records and bills. The monitoring guide explains how to log production so the numbers are on hand if a question arises later.

A simple illustration shows why the paperwork matters. Two neighbours install similar systems. One receives monthly bill credits that shrink the electricity charge, and the other signs a separate agreement to be paid for every unit sent out. On the surface the physical equipment is the same, but the first looks like self-supply and the second looks like a small power business. The tax treatment may differ for exactly that reason, and nothing about the panels themselves would tell you which is which. This is only an illustration with no figures, and it is not a ruling on any real case.

It is also worth remembering that rules for self-generators in a province can shift, as the net metering guide explains, and a change in the utility's billing model could change how the same system appears on paper. Re-check when the billing arrangement changes, not only at the time of purchase.
