Rent Expense

Definition

Rent expense is the periodic payment for the use of real or personal property owned by another party and used in the business. Real property rent covers commercial premises, storage, warehouses, and co-working space. Personal property rent covers equipment, vehicles not structured as purchased assets, and operating leases. Rent is one of the most frequently audited expense categories when related parties are involved because of s.67 reasonableness risk.

Key rules

• General deduction (s.18(1)(a)): rent is deductible when the premises or property is used to earn business income.
• Prepaid rent (s.18(9)): amounts paid in respect of services or the use of property that relate to a future year cannot be deducted in the year of payment. They are matched to the period they cover. This codifies the for prepaids.
• Related-party rent (s.67): rent paid to a shareholder, family member, or related corporation must be reasonable. Excess rent is disallowed and recharacterized, potentially as a shareholder benefit under s.15(1).
• Operating vs. capital lease: true operating leases are expensed; financing leases (in substance a purchase) are treated as the acquisition of a depreciable asset with the interest portion of each payment as interest expense. Under ASPE 3065 a financing lease transfers substantially all risks and rewards; IFRS 16 puts nearly all leases on-balance-sheet as right-of-use assets.
• GST/HST on rent: commercial rent on taxable real property carries GST/HST and is generally eligible for ITCs. Residential rent is exempt from GST/HST.
• Leasehold improvements: improvements made by the tenant are capital (typically Class 13), not an expansion of current rent expense.

Example

Whistler Studio Inc. signs a 24-month commercial lease on July 1, 2026 at $3,000/month plus 5% GST. The landlord requires first and last months' rent up front plus a $6,000 damage deposit.

For the July to December 2026 period, $18,000 of rent expense plus $900 ITC-eligible GST are deductible. The last month's rent of $3,000 is a prepaid expense on the balance sheet until June 2028. The $6,000 damage deposit is neither an expense nor a prepaid: it is a refundable deposit asset.

Scenario 2: Whistler Studio Inc. rents its studio from a corporation owned by the same sole shareholder. Market rent in the area is $3,000/month, but the corporations document $5,500/month. The $2,500/month excess fails s.67; $30,000 is added back on Schedule 1 annually. The recipient corporation still reports the full $66,000 as rental income unless the parties restate the invoices.

Common mistakes

• Expensing a large upfront lease payment in the year paid. s.18(9) requires matching to the periods covered.
• Capitalizing ordinary rent. Operating-lease rent is current expense, not a capital item.
• Missing ITCs on commercial rent because the landlord did not provide a GST/HST registration number on the invoice.
• Paying above-market rent to a related party and ignoring s.67.
• Treating a security deposit as an expense. Deposits sit on the balance sheet until forfeited or refunded.
