Many business owners are not aware of the tax write offs that can be deducted for tax purposes. Deductible expenses helps to minimize your taxes, it is often overlooked which expenses should be considered. In this blog, we will outline some the top deductions you should be aware about.

Legal and Accounting Fees

Many business owners pay there accounting and legal fees personally although the purpose is for business. By paying with a personal bank or credit card, the transaction is often missed during the bookkeeping process for the business. Not only is the annual accounting fees deductible expense but so are the incorporation costs.  Next time make sure you pay with your company bank or credit card. In case, you paid personally, have the corporation reimburse you tax-free.

Vehicle Expenses

There mainly two scenarios we encounter with clients, either the vehicle is owned personally or corporately. Each has a unique treatment and set of guidelines as tax write offs.

If the vehicle is owned corporately, the corporation will pay for all expenses to maintain the vehicle. This generally includes the following:

  • Gas
  • Repairs and Maintenance
  • Insurance
  • Registration fees
  • Parking fees (business purposes only)
  • Toll-routes (business purposes only)
  • Depreciation (tax calculation)
  • Lease payments (if leased only)

A logbook must be kept for all the mileage driven with the company vehicle. At the end of the year a standby charge and operating cost benefit calculation is done for all the personal kilometers driven with the company vehicle. This calculation is added as a taxable benefit to your personal income taxes.

If the vehicle is owned personally, you will pay for all the expenses to maintain the vehicle yourself NOT the company. However, you are entitled to a tax-free car allowance which the corporation will pay and you receive it tax-free. No receipts are required only a log book of all the mileage driven for business purposes with your personal vehicle. The current rates for 2016 are $0.54 cents for the first 5,000 KM driven and $0.48 cents for kilometers driven onward.


Work-in-home Office Space

If you use work space at home and 50% or more of the time it is used to do the main work or meet with clients, you are eligible for this expense. The work space used divided by the total livable space available in the home (square feet) multiplied by the total home expenses is a deductible expense. There are also other methods that can be used. The most common home expenses are:

  • Mortgage Interest
  • Property taxes
  • Home insurance
  • Repairs and Maintenance
  • Phone line, fax line and internet
  • Condo fees
  • Heat
  • Hydro and Utilizes

Be very careful with home capital expenditures as they can be denied in an audit as tax write offs.

Capital Assets used in Business

Assets purchased for business use are not 100% deductible in the year they are purchased. Instead they are depreciated at certain rates as per the income tax act. However, you still get the full benefit in terms of the tax-deduction and HST input tax credit over a period of year(s). The most common assets found in businesses and there rates are as follows:

  • Furniture and Fixtures (20%)
  • Computer Equipment (55%)
  • Computer Software (50-55%)
  • Vehicles (30%)
  • Building (4%)

It is a popular guideline to purchase assets towards the end of your fiscal year. The reason for this is because in the first year of depreciation, you only get to claim 50% of the maximum depreciation rate.
