# Canadian tax calendar: filing, instalment and RRSP dates > The dates that matter in the Canadian tax year, from slips and the RRSP deadline to filing day and instalments, with weekend shifts worked out for you Most of the Canadian tax year hangs on a handful of dates, and come tax time you probably need only two or three of them. This page lists them for the current year with the weekend shifts already worked out, and each one links to the tool or guide that goes with it. Who is it for? Almost everyone, for different reasons. If you earn a salary, the date that matters is the filing deadline in the spring. If you save in an RRSP, the contribution deadline falls 60 days after the year ends. If you work for yourself or run a business, the filing date moves to June 15, but any tax you owe is still due April 30, and quarterly instalments add four more dates to the year. Look early. A date you know about in the autumn is a plan, and the same date discovered in April is a scramble. Scan the list below, note the ones that apply to you, and follow the links to see what each needs from you. A phone reminder a week ahead heads off most late fees. We don't file anything for you, and the CRA's own pages are the final word on any date. ## Most read right now - [Last day to file taxes in Canada](https://tax-services.ca/articles/last-day-to-file-taxes-canada)April 30 for most people, June 15 for the self-employed, the weekend rule and a $2,000 late-penalty example. - [Canada tax season dates](https://tax-services.ca/articles/canada-tax-season)When the 2025 return opened and was due, what to gather and a refund example. - [RRSP limit and deadline](https://tax-services.ca/articles/rrsp-limit)The $2,000 buffer, the 1% monthly tax on excess contributions and the dates that matter. - [Tax instalments calculator](https://tax-services.ca/calculators/income-tax/tax-installments)Work out what to pay on the 15th of March, June, September and December. - [Tax refund timing in Canada](https://tax-services.ca/articles/tax-refund-canada)How long a refund takes, what holds one up and a $75,000 example. ## What are the dates this year? ## How are the dates worked out? The rules are the CRA's, and they're simple. The RRSP deadline falls 60 days after December 31. The filing deadline is April 30, or June 15 if you run a business. Instalments are due on the 15th of March, June, September and December. Any date that lands on a weekend moves to the next weekday. The weekend rule is easy to see in a real year. For the 2025 tax year, day 60 fell on Sunday, March 1, 2026, so the RRSP deadline slid to Monday, March 2, which is the date the [CRA's due dates and payment dates page](https://www.canada.ca/en/revenue-agency/services/tax/individuals/topics/important-dates-individuals.html) shows. Priya, a freelance designer in Calgary, is a good case for the other pair of dates. She has until June 15 to file, but if she owes a balance she still has to pay by April 30, so she pays an estimate in April and files later with her slips in hand. The [tax deadline page](https://tax-services.ca/income-tax/tax-deadline) gives the same dates with more detail on who they apply to. If you're relying on a date, check it against the CRA's own page too, because a rule can change between our yearly updates and you don't want to find out late. ## Which dates depend on you? A business that files GST/HST quarterly files one month after each quarter ends, while monthly and annual filers have other dates. Employers send payroll deductions on a schedule set by the size of their payroll. Neither fits on one calendar. The [sales tax guide](https://tax-services.ca/guides/gst-hst-pst) and the [payroll remittance calculator](https://tax-services.ca/calculators/business-tax/payroll-remittance) cover them, and if you work for yourself the [self-employed guide](https://tax-services.ca/guides/self-employed-and-small-business) ties several of these dates together. ## What if you miss a date? Don't panic, but don't sit on it either. The usual cost of missing the April 30 payment date is interest on what you owe, and a late filing can add a penalty on top, so the sooner you file and pay, the less it grows. If you can't pay in full, still file on time. The [guide to dealing with the CRA](https://tax-services.ca/guides/dealing-with-cra) covers what to do when a letter arrives. ## What should you do next? Is a date close? The [filing guide](https://tax-services.ca/guides/file-your-taxes) lists what you'll need to gather, and the [checklists](https://tax-services.ca/checklists) turn that into a sheet you can print. Planning an RRSP contribution before the deadline? Try the [RRSP calculator](https://tax-services.ca/calculators/rrsp-retirement/rrsp-calculator) and see what it saves you. The year's limits are on the [limits and rates page](https://tax-services.ca/tax-numbers), and anything the CRA announces in between turns up on the [tax news page](https://tax-services.ca/tax-news).
