Shopping: The best time to buy assets/expenses for business owners is close to year end, and claim expenses/depreciation for the whole year such as: printer, laptop, desk, furniture.
Events: Annual business events, such as Christmas parties or similar, are good opportunities to celebrate whilst being able to claim the expenses. Claims are 100% for the entire year if the employer sponsors events to all employees.
Note: Limited to six events each year (T4002 Business and Professional income)
