Home business accountant in Mission
Reviewed by EverStone CPA · July 2026
A large share of Mission’s businesses are run from home — trades administered from a garage office, online sellers, consultants and service operators working the commuter corridor. EverStone works with incorporated owners and is a Mission small business CPA, at fixed fees, online.
Quick answer: Home-based Mission businesses run into three questions early: how much of the house is genuinely deductible, whether to incorporate yet, and how GST and PST apply when you sell a mix of services and goods. EverStone handles all three alongside the return, at a fixed fee agreed before work begins.
The home office claim, and what supports it
Where your home is genuinely the base of the business, workspace costs are deductible in proportion to the share of the home actually used to earn income. That proportion is the part people get wrong — claiming a whole spare room used mainly for storage, or claiming nothing at all because it seemed complicated. The claim rests on the space being used for the business consistently, and on being able to show it. It is one of the more commonly reviewed items on a small return, which is a reason to set the basis properly rather than an argument for skipping it. Our home office guide covers the mechanics.
When incorporating starts to make sense
Most home businesses start as sole proprietorships and reach a point where a corporation is worth the added administration. The tipping point has less to do with a revenue figure than with how much profit you leave in the business. Incorporating can bring deferral where you consistently earn more than you draw, liability separation, and a cleaner structure for holding equipment or taking on help — and it adds a corporate return, more formal bookkeeping and real record-keeping obligations.
If you spend essentially everything the business earns, the advantage narrows quickly. We map it against your actual drawings rather than a rule of thumb, including the cases where staying a sole proprietor is still the better answer this year. See incorporating versus sole proprietorship in BC.
Selling a mix of goods and services
A home business that sells both a product and a service is applying more than one sales-tax rule at once. GST and BC’s provincial sales tax do not cover the same things, and a bundled offering can be treated differently from the same items sold separately. Online sellers add the question of where the customer is, because the applicable rules generally follow the place of supply rather than where you pack the boxes. Most owners get this approximately right at the start and discover the gap later, which is more expensive than setting it up once.
Vehicles, equipment and the personal-use line
Home businesses run on shared assets — the family vehicle, a laptop, tools kept in the garage. Deductibility follows business use, and business use has to be demonstrable rather than estimated after the fact. A mileage log is the single highest-value habit here. Larger equipment is capital rather than an expense and is recovered through capital cost allowance at a rate set by its class, which also means a disposal later has tax consequences worth anticipating.
Keeping it separate from personal money
The most common structural problem in a home business is not a wrong deduction — it is a bank account doing double duty. Mixed personal and business spending makes every other question harder to answer and much harder to support. Once incorporated it also creates a specific trap: money taken out that was never declared as salary or a dividend is a shareholder loan, and a loan left outstanding past the deadline gets included in personal income. Our shareholder loans guide covers it.
Growing out of the house
The point where a home business takes on premises or a first employee is where the accounting stops being simple, and it usually arrives faster than planned — a contract requires help, or the garage stops being big enough. From that moment there is rent or a lease to account for, source deductions on a remittance schedule set by your withholding, year-end slips, and a much sharper line between the business’s money and yours.
It is also the point where the home office claim usually shrinks or disappears, because the base of operations has moved. Owners often carry the old claim forward out of habit, which is exactly the kind of quiet inconsistency that is difficult to defend later. The useful move is to review the whole structure in the year the change happens rather than the year after — premises, payroll, how you pay yourself, and whether incorporation now makes sense if it did not before. See your first 90 days for how we set that up.
