Affordable T1 Adjustment for Canadian Businesses and Individuals

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.

CRA online filing for 2025 returns opened on 23 February 2026 and stays open until 29 January 2027. You can prepare a return before the service opens, but it cannot be transmitted, and slips such as T4s and T5s often arrive only in late February. Filing early makes sense if you expect a refund. If you expect a balance owing, you can still file early and pay by 30 April 2026.

Yes. Most people file electronically through NETFILE using CRA-certified software, which submits the return directly and confirms receipt immediately. Filing online is also what makes a fast refund possible: for 2025 returns filed in 2026 the CRA service standard is about two weeks online, against a considerably longer standard for a paper return, and registering direct deposit removes the cheque step. CRA online filing for 2025 returns opened 23 February 2026 and closes 29 January 2027.

Pay through your bank's online banking by adding the CRA as a payee and choosing the right account and year, through My Payment with a debit card, by pre-authorised debit scheduled in My Account, by credit card through a third-party provider that charges its own fee, or at a bank counter with a remittance voucher. For 2025 personal returns the payment deadline was 30 April 2026, including for the self-employed, and interest runs daily on anything unpaid after that.

A non-refundable credit reduces the tax you owe to zero but no further, so any unused part is lost, carried forward, or transferred to a spouse or parent where the rule allows it. A refundable credit is paid to you even when no tax is owed, which is how benefit-style payments reach people with little or no income. Most personal credits on the federal return, including the basic personal amount, are non-refundable.

Your refund is the tax already withheld or paid by instalments minus the tax you actually owe after credits and deductions, so the amount depends entirely on your own numbers - there is no standard figure. Timing is more predictable: the CRA aims to process an online return in about two weeks, and up to 16 weeks for a non-resident return. Direct deposit is faster than a cheque, and amounts owing to government can be offset.

There is no single answer, because provincial rates and personal credits change the result. The mechanics: federal tax for 2026 begins at 14% on the lowest bracket, and the basic personal amount of $16,452 shelters the first slice of income. Your province applies its own brackets and credits on top, and CPP and EI contributions come off separately. Run your province and pay period through the CRA's payroll deductions online calculator for a reliable figure.

Your refund or balance is on the notice of assessment for the year, and in CRA My Account under that year's return. Both show the exact figure the CRA used. If you are calling and cannot verify your identity, the agent may ask for an amount from a line of a recent return instead, which you can read off the assessed copy in My Account. A refund can also differ from what your software predicted, because the CRA adjusts claims it disallows.

No product moves you up the queue. Every program approved by the CRA for NETFILE transmits to the same place and gives identical timing, roughly two weeks for an online return. The CRA does the assessing, so the software brand has no bearing on it. What genuinely shortens the wait is direct deposit and a return that matches your slips. Delays come from reviews, missing information, or amounts owed to government being set against the refund.

CIT stands for corporate income tax, the tax a corporation pays on its own profits and reports on a T2 return rather than a personal return. For 2026 a Canadian-controlled private corporation claiming the small business deduction pays a federal rate of 9% on the first $500,000 of active business income, with the federal general net rate at 15%, and a provincial rate applies on top. The T2 return is due six months after the fiscal year end, but the tax itself is due earlier: two months after year end, or three months for a Canadian-controlled private corporation that claims the small business deduction and meets the other conditions.

Accommodation is taxable, so GST/HST applies at the rate of the province where the room is: 5% GST alone in Alberta and the territories, 13% HST in Ontario, 15% in New Brunswick, Newfoundland and Labrador and Prince Edward Island, and 14% in Nova Scotia for 2026. Provinces with their own sales tax, and many cities, add accommodation or destination levies on separate lines. Tax on business travel may be recoverable as an input tax credit.

A criminal record check you pay for to get or keep a job is not deductible, because an employee may only claim the narrow set of employment expenses the tax rules allow and this is not among them. A business that pays for checks on staff or contractors may deduct the cost as an ordinary operating expense, and so may a self-employed person who must hold a current check to do the work being billed. Keep the receipt either way.
