KPMG Canada flags 2026 tax rate changes for reporting teams

KPMG Canada’s latest rate tables put a 15.0% federal active-business rate, plus province-level changes, directly into the quarter-end and year-end workflow. Under IFRS Accounting Standards and ASPE, enacted tax law changes are recognized in the period that includes the substantive enactment date, so deferred tax balances, current provisions and disclosures cannot wait until the next cycle.

The rates that move the close

KPMG Canada published its Tax Accounting - 2025 Tax Rates and Other Changes update on January 8, 2026, followed by a Q1 2026 Update on April 7 and a Q2 2026 Update on July 6. The firm also refreshed its Canada tax-rate tables as the year progressed, with one substantively enacted income tax table current as of March 31, 2026 and another 2025-and-2026 table current as of December 31, 2025.

The core federal math is straightforward: a 38.0% general corporate rate, less a 10.0% federal abatement and a 13.0% rate reduction, produces a 15.0% federal active-business rate. Provincial active-business rates in the 2026 table include British Columbia at 12.0%, Alberta at 8.0%, Saskatchewan at 12.0%, Manitoba at 12.0%, Ontario at 11.5%, Quebec at 11.5%, New Brunswick at 14.0%, Nova Scotia at 14.0% and Prince Edward Island at 15.0%.

The 2025-and-2026 table shows Saskatchewan rising from 10.0% in 2025 to 12.0% in 2026, while Ontario moves from 10.0% to 11.5%. For tax provision teams and controllers, those are the kinds of shifts that can alter effective tax rate forecasting, deferred tax remeasurement and disclosure language even when the headline change looks modest.

Where the reporting pressure lands

The accounting rule that drives the urgency is the substantive enactment date. Canadian income tax rate and other changes may need to be reflected in financial statements under IFRS Accounting Standards, ASPE or U.S. GAAP, and under IFRS and ASPE the change is recognized in the period that includes that enactment date.

That means the decision cannot be deferred to the next filing. Teams have to determine whether a rate change is substantively enacted now, then remeasure existing temporary differences, refresh the current and deferred tax calculations, and update uncertain tax positions where the changed law affects the analysis. In practice, the close checklist becomes a legal-timing exercise as much as an accounting one.

A clean way to think about the work is:

• confirm which rate changes are substantively enacted and on what date
• remeasure deferred tax balances tied to existing temporary differences
• update effective tax rate forecasts for the current quarter and full year
• review uncertain tax positions and related disclosures
• make sure the documentation is ready for audit review

That workflow changes the shape of the workpaper package. A tax-law update can ripple into review procedures around estimates and controls, which means audit teams need enough support to see not only the revised numbers but also the logic behind when the change was booked.

Indirect tax is not separate work

Indirect-tax work is not separate from the close: GST/HST, QST and provincial sales tax obligations bring their own compliance calendar. In a December 11, 2025 publication, KPMG advised Canadian and non-resident businesses to undertake regular reviews to ensure they are meeting their indirect tax obligations.

For reporting teams, indirect tax affects more than remittances. It can change invoicing logic, pricing assumptions and cash-flow forecasts, which means finance teams need to keep operations, tax and accounting aligned instead of treating sales tax as a back-office filing issue. A rate or rule change that looks routine can still force a system update, a controls review or a fresh check of how amounts are booked at month-end.

Income tax provision work may start with the corporate rate tables, but indirect taxes can affect the same forecasts, the same controls and the same close calendar if billing and cash collections move.

What KPMG practitioners cannot put off

For KPMG tax and audit professionals, this kind of country update becomes a live checklist for client work. For teams supporting a Canadian subsidiary or a cross-border group, the non-deferrable decisions are the ones that determine what gets booked now versus monitored later: the enacted rate, the deferred tax remeasurement, the impact on temporary differences, and the disclosure language that will go into the financial statements.

In due diligence, valuation and purchase accounting, even routine rate changes can alter forecasted cash taxes and the treatment of net operating losses. For advisory teams, that means the tax memo has to connect the statutory change to the deal model, not just to the provision schedule.
