Québec Automobile Deduction Limits and Rates for 2018

Tax Development Jan 22, 2018

Québec Finance has announced the automobile expense deduction limits and the prescribed rates for automobile operating expense benefits that apply for the 2018 taxation year.  Based on the principle of substantial harmonization between the Québec and Canadian federal tax legislation, the province has announced that it will adopt the rates and limits for 2018 that were put in place by the federal Department of Finance on December 22, 2017.  This year’s announcement is similar to the 2017 release, with only two rates changing from the previous year.  Specifically, the rates in effect as of January 1, 2018 are as follows:

  • The general prescribed rate used to determine the taxable benefit relating to the personal portion of automobile operating costs increases by 1 cent to 26 cents per kilometre (for taxpayers employed principally in the selling or leasing of automobiles, the prescribed rate also increases by 1 cent to 23 cents per kilometre);
  • The limit on tax deductible per kilometre allowances paid to employees for using their personal vehicles for business purposes increases by 1 cent to 55 cents per kilometre for the first 5,000 kilometres, and to 49 cents per kilometre thereafter (these rates are 4 cents per kilometre higher in the Northwest Territories, Yukon and Nunavut);
  • The capital cost allowance limit for passenger vehicles purchased in 2018 remains unchanged at $30,000, plus GST and QST;
  • The limit on deductible leasing costs stays at $800 per month (plus GST and QST) for leases entered into after 2017 (under a separate restriction, deductible leasing costs are prorated where the value of the passenger vehicle exceeds the capital cost ceiling); and
  • The maximum allowable interest deduction for amounts borrowed to purchase a passenger vehicle is $300 per month for loans related to vehicles acquired after 2017.

Please note that the above limits and rates may be subject to the input tax refund restriction for large businesses.
