Expert Tax Accountants in Lethbridge

Canadian income tax is built up in layers. You total your income for the year, subtract the deductions you qualify for to arrive at taxable income, then apply the federal brackets and your province's brackets to that figure. Each bracket rate applies only to the income sitting inside it, so earning more never retaxes the dollars below. Non-refundable credits, starting with the basic personal amount, come off the tax afterwards. Look up the CRA bracket table for the tax year you are filing.

If you owe nothing, no penalty applies, but a refund and benefit payments such as the Canada child benefit and the GST/HST credit are held up until the return is processed. If you owe, a late-filing penalty is charged and interest runs on the balance and compounds daily from the day after the due date. For the 2025 tax year the deadline was 30 April 2026. File even if you cannot pay, because the penalty is driven by filing, not payment.

There is no single percentage. Canada uses graduated brackets, so the rate climbs as income climbs and each rate applies only to the income falling inside its own bracket. Your total combines a federal bracket with your province's bracket and is then reduced by credits, which is why two people on the same salary in different provinces pay different amounts. The share withheld from a paycheque also covers CPP or QPP and EI. Check the CRA bracket table for the year concerned.

Medical costs give a non-refundable credit rather than a deduction. Eligible items include prescription drugs, dental work, eyeglasses and contact lenses, fees paid to medical practitioners authorised to practise, private health plan premiums, attendant care and travel for treatment unavailable locally. Over-the-counter products and most cosmetic procedures do not qualify. Only the portion above an income-based threshold counts, the claim period may end at any point in the tax year rather than following the calendar year, and pooling the family claim on one spouse usually helps.

There is no standard amount. The refund equals tax withheld and instalments paid, less the tax calculated on the return after deductions and credits, so two people on the same salary can end up with very different results. Payroll withholding that ran higher than needed, RRSP deductions, tuition and medical claims and spousal transfers all push the figure up. The notice of assessment confirms the final number once the return is processed.

Start from gross pay, take off federal and provincial income tax on your taxable income, then take off CPP and EI. For 2026, employee CPP is 5.95% on earnings between the $3,500 exemption and the $74,600 ceiling, with CPP2 at 4% up to $85,000, and EI is $1.63 per $100 of insurable earnings up to $68,900. Federal rates for 2026 run from 14% to 33%. The CRA's payroll deductions online calculator does the arithmetic.

Tax legislation is the written law that imposes and administers tax: federally the Income Tax Act and the Excise Tax Act, plus each province's own statutes and the municipal bylaws behind property tax. A change usually begins as a budget announcement, is drafted into a bill, passes Parliament and takes effect on royal assent. Regulations and CRA guidance sit beneath the statutes and explain administration without replacing them. Some proposals are administered before they pass, and a few never do.

Preschool and nursery school fees generally qualify as child care expenses, because the care lets a parent work, run a business or study. Fees for the educational portion of a program at a school can be excluded, so ask the provider for a receipt that separates child care from tuition. The claim normally goes on the lower-income spouse's return and is capped by the child's age and earned income. See the CRA child care expenses page.

13% is Ontario's HST: the 5% federal GST and Ontario's provincial share charged as a single tax. To add it, multiply the pre-tax price by 1.13. Elsewhere the rate is 15% in New Brunswick, Newfoundland and Labrador and Prince Edward Island, 14% in Nova Scotia since 1 April 2025, 5% GST alone in Alberta and the territories, and 5% GST plus a separate provincial tax in British Columbia, Saskatchewan, Manitoba and Quebec.

Tax administration is the work of collecting and enforcing tax rather than setting it. Parliament and the legislatures write the law; the Canada Revenue Agency administers it, processing returns, issuing assessments and refunds, running reviews and audits, charging penalties and interest, and collecting balances owing. Revenu Quebec administers Quebec's provincial system alongside it. Administration also covers the service side: My Account, payment arrangements, and taxpayer relief requests to cancel penalties and interest.

The rate is the same. The payment is added to your income for the year and taxed at your marginal rates like any other pay. What differs is the withholding. Pay in lieu of notice runs through normal payroll deductions, while a retiring allowance has tax withheld at flat lump-sum rates that can be higher or lower than what you ultimately owe. The difference is settled when you file your T1, so a large payout often produces a refund or a balance.

TRACS is Alberta's Tax and Revenue Administration Client Self-Service portal. Corporations and other filers use it to submit and view Alberta provincial returns, make payments, check balances and authorise representatives. It matters because Alberta does not have the CRA administer its corporate income tax: an Alberta corporation files a federal T2 with the CRA and a separate Alberta corporate return with the province through TRACS. Quebec runs a comparable system.
