Solar and Tax: A Guide for Small Businesses
For a small business, the tax side of solar mainly depends on who owns the system, how it is used and what incentives apply, so ownership and records matter more than the headline price. This is general information only; an accountant should confirm how the rules apply to your business.
Start with who owns the equipment
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.
Buy, lease or pay per unit of power: the three common structures put the tax benefits in different hands. A buyer owns the asset, may claim depreciation, and may be eligible for a business credit if the equipment qualifies. A lessee generally deducts the lease payments, and the lessor holds the asset. A power purchase arrangement looks like a utility bill to the customer. Compare these structures with the financing options guide, then ask an accountant which fits your tax position. A business with little taxable income may not be able to use tax-based benefits, which makes the owner's tax capacity a real input.
Small businesses also face a practical question that large firms rarely do: the owner often pays personally for things the business uses. If the system is bought in an owner's name and used by a company, the ownership paper trail may not match the tax claim. Sort out which legal entity buys, which signs the utility agreement and which claims, and put it in writing before the first payment. Retrofitting that paperwork after the fact is slow, and an accountant will usually prefer to hear about it at the quote stage.
Timing of the purchase against the business's fiscal year end can matter too, since in-service dates drive when deductions begin. Ask your accountant what year the system will fall into, based on the likely commissioning date and not the date of the deposit.
What can be claimed, in concept
There are two main concepts. One is depreciation, called capital cost allowance in Canada, explained in the CCA guide. The other is an investment tax credit for qualifying clean equipment, described in the clean technology credit guide. Operating costs such as maintenance and monitoring are generally ordinary business expenses. Interactions between grants, credits and depreciation can reduce one another, so do not add up benefits from separate sources without checking.
Farms, shops and rental buildings
A farm may use power for pumps, fans, drying and shops, and an array there is often a business asset. A shop or office with an attached suite may need a split between business and non-business use. A landlord who owns a building and tenants who pay their own power raises further questions about who benefits from the production. Think about who consumes the electricity and who receives the bill credits. The guide on solar income covers what happens when power is sold or credited and why contract wording matters.
Record-keeping that pays off
Create one folder for the project with the contract, quotes you rejected, the final invoice, proof of payment, permits, utility approval, commissioning sheet, warranty documents and photographs of the installation. Add annual production data and any bill credits. Keep it as long as an accountant advises, which is usually longer than people expect. The warranty guide explains why the same documents matter for repairs.
Discipline of this kind is how long-running projects stay credible. The Drake Landing community was measured for years, and the results are in the performance results.
Questions to bring to an accountant
- Which structure, purchase or lease, suits our tax position?
- Does our system qualify for any business credit, and what conditions apply?
- How do grants affect the depreciation base?
- How should we split use if part of the building is not business?
- What should be on the invoice to support the claim?
Take the quotes along, ideally compared as described in the quote comparison guide, and the Canada Revenue Agency's current guidance for business expenses and capital assets. The agency's enquiries line can answer narrower questions.
Quick answers
Can a small business claim a solar tax credit?
Some federal measures have been aimed at businesses, with conditions on equipment, ownership and use. Check the Canada Revenue Agency's current guidance and ask an accountant.
Is it better for a business to lease or buy solar?
It depends on the business's tax capacity, cash and appetite for ownership risk. Ownership determines who can claim depreciation or credits, so ask an accountant before choosing.
What records should a business keep for a solar project?
Keep the contract, final invoice, proof of payment, permits, utility approval, commissioning sheet and production data. These support both tax claims and warranty claims.
