If you paid salary, employment commissions or employee benefits from January 1 to December 31, 2015, you must complete and file:

  • T4 Summary and Supplementary reporting forms provided to you by the federal government.
  • Retiring allowances, including termination and severance pay, must be reported on T4s.  Note that amounts eligible for transfer to an RRSP are reported separately on this form from those that are ineligible for such transfers.

By March 15, 2016

Employers must complete and file the Ontario Employers' Health Tax Annual Return. You should receive this return from the government in January 2016.

Employers are exempt from Ontario Employers' Health Tax on the first $450,000 of Ontario payroll. This exemption must be shared among associated employers. This exemption is eliminated for private sector employers with annual Ontario payrolls over $5 million.

Other filings

Employers are required to complete and file Ontario Workers' Compensation Returns on the dates indicated on their particular forms.


In preparing the T4s for your employees, you must calculate and report the value of all employee benefits in addition to reporting actual salary or wages.

See the latest version of the "Employers' Guide – Taxable Benefits and Allowances", available on the CRA website for a detailed listing of benefits.

Ensure that all employee benefits that are taxable supplies (other than special-rated employer-paid automobile operating expenses, exempt supplies or zero-rated supplies) are grossed up for the effect of the Harmonized Sales Tax (HST).

See Appendix I to help you calculate complex GST/HST-included automobile benefits and employee loan interest benefits.

On each employee's T4, you must report contributions to Registered Pension Plans in 2015 and his/her pension adjustment (PA) figure for the year. Your plan administrator can assist you in
determining your employees' PA figures, the calculation of which is quite complex for defined benefit plans.

T4 forms are available at our office, and we can assist you in their preparation.

All taxpayers

By February 29, 2016

You must complete and file a T5 Summary and Supplementary reporting form if you:

  • paid or owed accrued interest (generally, from inception to each anniversary day);
  • paid dividends (including eligible and non-eligible dividends, and certain deemed dividends); or
  • paid royalties.

Please note that exceptions to this rule include:

  • interest paid by one individual to another, such as interest paid on private mortgages;
  • interest paid on loans from banks or other financial institutions;
  • interest paid or credited to non-residents of Canada (which must be reported on separate NR forms);
  • capital dividends paid to Canadian residents by corporations; and
  • total amounts paid for the year if they are $50 or less per recipient.

Electronic filing

If you file more than fifty T4 slips or fifty T5 slips for a calendar year, you must file the information returns over the internet.

T5 forms are available at our office, and we can assist you in their preparation.

Be sure to use current versions of T4 and T5 Summaries and Supplementaries to accommodate government scanning requirements.

By March 30, 2016

If you are the trustee of an inter-vivos trust or a testamentary trust with a December 31, 2015 year-end, you must complete and file the following:

  • T3 Trust return and supplementary forms by March 30, 2016. Please note the requirement to separately disclose eligible and non-eligible taxable dividends; and
  • T4 and T4A reporting forms for executor or trustee fees paid (as noted above, these are due by February 29, 2016).

By March 31, 2016

If you have paid or credited an amount to a non-resident of Canada such as:

  • investment income (interest, dividends);
  • estate or trust income;
  • pension or annuity income;
  • rents; or
  • royalties,

You must complete and file an NR4 Summary and Supplementary reporting form by March 31, 2016 (or March 30, 2016 if the reporting taxpayer is a trust or estate).

Forms are available at our office, and we can assist you in their preparation.

Information Collection and Use

We require site users to register with Mondaq (and its affiliate sites) to view the free information on the site. We also collect information from our users at several different points on the websites: this is so that we can customise the sites according to individual usage, provide 'session-aware' functionality, and ensure that content is acquired and developed appropriately. This gives us an overall picture of our user profiles, which in turn shows to our Editorial Contributors the type of person they are reaching by posting articles on Mondaq (and its affiliate sites) – meaning more free content for registered users.

We are only able to provide the material on the Mondaq (and its affiliate sites) site free to site visitors because we can pass on information about the pages that users are viewing and the personal information users provide to us (e.g. email addresses) to reputable contributing firms such as law firms who author those pages. We do not sell or rent information to anyone else other than the authors of those pages, who may change from time to time. Should you wish us not to disclose your details to any of these parties, please tick the box above or tick the box marked "Opt out of Registration Information Disclosure" on the Your Profile page. We and our author organisations may only contact you via email or other means if you allow us to do so. Users can opt out of contact when they register on the site, or send an email to with “no disclosure” in the subject heading
