When you set up a home office, you'll likely buy a desk, chair, shelving, and lighting. Some of these costs can be claimed on your 2026 tax return, but the CRA treats them differently depending on whether they're supplies, equipment, or capital assets. As a general rule, items that cost under $500 and wear out within a year (like office supplies) are fully deductible, while permanent fixtures and furniture may need to be depreciated using Capital Cost Allowance (CCA) rules. Installation costs usually follow the same treatment as the item being installed. The CRA divides home office costs into three categories: Fully Deductible in Year of Purchase - Office supplies (paper, pens, notebooks, printer ink) - Printer cartridges and toner - Desk accessories under $500 - Small task lamps and USB chargers - Cleaning supplies for your office space - Printer paper and filing supplies May Be Subject to CCA (Depreciated Over Time) - Office furniture (desks, chairs, filing cabinets) over $500 - Computer equipment (monitors, keyboards, mice) - Shelving units and storage systems - Office lighting fixtures (if permanently mounted) - Artwork and decorative items over $500 Not Deductible - Personal furniture that happens to be in your home
Yes, installation costs are added to the cost of the item itself. If the item plus installation totals under $500, you can deduct it fully in that year. If the total is $500 or more, both the item and installation are depreciated using CCA rules.
Office supplies (paper, ink, pens) are consumed within a year and are fully deductible in the year purchased. Office equipment (desks, chairs, monitors) lasts longer and items over $500 must be depreciated over time using CCA.
No. Since it's under the $500 threshold, you can deduct the full $450 in the year you bought it. However, if you paid $50 for delivery and installation, making the total $500, then it becomes subject to CCA depreciation.
No. The CRA only allows deductions for expenses incurred for business purposes. Personal furniture moved into your home office doesn't qualify as a new business expense, though brand-new furniture purchased specifically for the office does.
Most office furniture falls under Class 8, which has a 20% declining-balance depreciation rate. Computer equipment is Class 45 with a faster 45% rate. You claim a percentage of the remaining balance in the CCA pool each year.
