A simple guide to tax deductible business expenses
Read time: 7 minutes
It’s tax season: With all of your receipts in hand, it’s time to start organizing them to file your tax return for your business.
Generally, individuals have to file their tax returns by April 30. However, if you, your spouse or common-law partner are self-employed, you have until June 15 to file your return. But be careful if you have a balance owing; the CRA begins charging interest on any unpaid amounts owing starting on May 1.
Corporations can choose any date for their fiscal year end. Taxreturns must be filed no later than six months after the end of each tax year for corporations.
What can I deduct for my business taxes?
Generally, all businesses can deduct from their income expenses that are incurred not only to make the business operational, but also to maintain that business once it is up and running.
The CRA has a list of the common business expenses that you can deduct.
The important thing is that the expenses must be incurred to earn the business income and they must be reasonable under the circumstances.
“They must be supported by original invoices,” says Chantal Trépanier of the CRA’s Liaison Officer Service.
“There is a lot that you can claim. It’s about proportion and being reasonable.”
In terms of timing, the only restriction is that expenses incurred in a business's fiscal year must be claimed against income earned in that year. There are wrinkles to this process relating to accounting methods (income or expenses secured in a fiscal year, but not actually paid until the following year, must be included, for example).
You can refer to the table below for examples of the main operating expenses you can claim when filing your taxes.
The main operating expenses you can deduct from your taxes
You can deduct expenses that preceded the operation of the business. However, you can only claim expenses if you operated the business in the fiscal period in which the expense was incurred.
