Canadian Tax & Finance Calculators
Plan with confidence. Free, accurate calculators for income tax, take-home pay, GST/HST/PST, RRSP, TFSA, capital gains, corporate tax, self-employment, mortgages and car loans — covering every province and the current 2026 tax year plus the previous five.
Numbers drive good financial decisions. Whether you are weighing a job offer in Edmonton, planning an RRSP top-up before the deadline, pricing a vehicle, or estimating what your corporation will owe, these calculators give you a fast, reliable answer grounded in the latest federal and Alberta figures. They are built and maintained by BOMCAS Canada, a professional tax accounting firm in Sherwood Park, and they reflect the same rates we use in client work.
Every tool runs entirely in your browser — nothing you type is sent to a server or stored — and each one lets you switch province and tax year so you can compare scenarios side by side.
