Tax Changes for 2018/19


Tax Changes for 2018/19


Whether you prepare the return yourself or have them prepared by your CPA, it’s almost time for all Canadians to be gathering their paperwork together for their 2018 personal tax returns. So, what changes for 2018 might affect your business? And, what other tax changes are coming into effect in 2019?

Changes Affecting Canadian-Controlled Private Corporations

The federal small business tax rate decreased to 10% as of January 1, 2018, and by a further one percent to 9% as of January 1, 2019. The personal tax rate for ineligible dividends increased to offset those decreases in order to maintain “integration” – the concept that the tax burden for income earned by an individual personally should approximate the combined corporate and personal tax paid if that income was earned through a corporation and then paid out as a dividend to the individual.

Ineligible dividends are those that are paid out of corporate income that has benefitted from preferential tax treatment, either through:

  • the reduced small business tax rate noted above, or
  • the refundable dividend tax treatment for certain investment income earned in private corporations

Changes to the Tax on Split Income (TOSI) Rules

Possibly the most significant tax changes are those affecting the shareholders of private corporations.

The TOSI rules were first introduced in 1999. They were developed in order to limit the benefit of tax structures that mainly aimed to reduce a family’s overall tax burden by splitting income with minor children.

The 2017 federal budget identified similar concerns with income split between adult family members, and new rules were introduced that became effective January 1, 2018. These new rules are complex, but essentially they extend the TOSI rules to adult family members. Some sources of income are exempt from the TOSI rules, with different exemptions applying to those between 18 and 24 years old from those that apply to Canadians 25 or older.

Excluded business

Income from an excluded business will not be subject to the TOSI rules for individuals between 18 and 24 years old. The excluded business rules focus on the individual’s contribution to the business, and require that the individual has been actively involved in the business on a regular, continuous and substantial basis. Income for adults in this age group would also be excluded if it is under a specific amount, which is calculated using a legislatively-prescribed rate applied to the value of the assets that the individual has contributed to the business.

Excluded shares

In addition to the excluded business exception, Canadians 25 years and older have additional exceptions for both of the following:

  • income from excluded shares, which apply where the individual owns more than ten percent of a non-services-based company
  • a “reasonable” return based on the contributions of the individual. These contributions may be financial (capital contributed), based on one or both of:
    • the work that he or she does (after considering any remuneration they already receive for that work)
    • risks that he or she has assumed

There is an additional exception for spouses over 65 years old.

Changes to Taxation of Passive Income

In addition to the changes just discussed – and which affect the shareholders of private corporations – there are also changes, effective for taxation years beginning after 2018, to the taxation of passive income earned within a Canadian-controlled private corporation (also known as a “CCPC”).

These rules are designed to limit the deferral advantage available to these private corporations, since they invest income that has been taxed at the low small business rate passive investments are subject to. In contrast, individuals who earn income personally would pay higher tax, and therefore would have less
after-tax income to invest.

These changes to taxation of passive income reduce the access to the small business tax rate by $5 for every $1 of “adjusted aggregate investment income” above $50,000. They are also very complex, especially since some provinces, such as Ontario, have announced that they will not parallel the new federal passive income rules.

Other Changes

The new year brought in increased Canada Pension Plan (CPP) contributions designed to fund the enhanced CPP benefits in the future. However, a slight offset to those higher CPP rates exists and will be noted, as the Employment Insurance contribution rates have decreased. For more information, please see

The federal government’s new carbon pricing mechanism will also come into effect in those provinces that do not have a carbon pricing mechanism of their own. This will result in increased costs for fossil fuels and the services that they support starting in April 2019, with a direct rebate to consumers to offset some of those cost increases.

Other than the changes discussed above to the tax rate for ineligible dividends, no changes are coming to the personal tax rates for other sources of income: salary, capital gains, and eligible dividends (generally those from public companies). The tax brackets and personal credit amounts are adjusted for inflation.

The public transit tax credit was eliminated as of July 1, 2017, so you might notice this credit disappearing completely for 2018 when you prepare or review your tax return. Also new for 2019: low-income workers can qualify for an increase in the Canada Workers Benefit. However, they will not receive the extra money until 2020.

In summary, while there were relatively few changes to the tax rules in 2018/19, those changes that were introduced for private corporations and their shareholders are complex and may have a significant impact on those affected. To see if these changes affect you or your business, it’s worth meeting with your CPA.
