WinRAS - Calculation of Source Deductions and Employer Contributions

Important

WinRAS was updated further to the publication, on August 15, 2018, of information bulletin 2018-7, in which the Ministère des Finances announced a new plan to reduce the health services fund contribution for 2018 by:

  • increasing the total payroll threshold, above which the contribution rate for small and medium-sized businesses (SMBs) is reduced, from $5 million to $5.5 million; and
  • reducing the contribution rate (subject to certain conditions) for employers outside the public sector whose total payroll is less than $5.5 million.

The 2018 update also takes into account the Budget Speech given on March 27, which announced that the rate of the tax credit for the acquisition of Fondaction shares after May 31, 2018, would be maintained.

Be sure to use the right version of WinRAS for the pay period.
