Whizi Canadian Tax

Whizi Canadian Tax answers the Canadian tax questions accountants and business owners look up every week, with the current figures from canada.ca.

Ask about a CRA deadline, limit, rate or form and you get a card with the headline figure, a short answer, the key numbers beside it and the date it was last checked. It covers 400 questions across the 2025 and 2026 tax years: payroll (CPP, CPP2, EI, remittance due dates, T4 and T4A slips), personal tax (T1 deadlines, brackets for every province, credits, RRSP, TFSA, FHSA, RESP and RRIF rules), corporate tax (T2 deadlines, the small business deduction, CCPC rules, dividends, GRIP and RDTOH), GST/HST, trusts and estates, non residents and self employed income.

Every answer comes from a Whizi page built on canada.ca and the Income Tax Act, and each card links to the full answer with its worked examples and every source.

It is read only. It needs no account and stores nothing you ask. When a question falls outside what it covers, it says so instead of guessing.
