Updated Checked by the Tax-Services.ca editorial team How we check
The easiest way to stay updated with accounting changes in Canada is to let the sources come to you. Subscribe to the CRA’s business mailing lists, add your email address to My Business Account, and set aside a fixed slot each week to read what arrived. That covers tax. Accounting standards are a separate track and move on a different clock.
Which CRA mailing lists are worth joining?
The CRA runs several electronic mailing lists, and you pick only the ones that match your business. Here’s what its subscription page offers to businesses.
| List | What it sends |
|---|---|
| Businesses tax information newsletter | New or updated business information, news, tips and local events |
| Payroll | Payroll deductions, tax tables, taxable benefits, calculators, seminars and employment insurance information |
| GST/HST technical publications | Memoranda, bulletins and policy papers |
| Excise and GST/HST news | Quarterly news on tax and duty administration |
| Stakeholder messages | Emails matched to your industry |
| Electronic filing of information returns | Website changes and filing resources for filers |
If you have staff, the payroll list is the obvious pick. If you only sell goods, the GST/HST news covers more of your world. A freelance designer in Victoria with no employees might take the business newsletter and the GST/HST news and stop there.
Don’t subscribe to everything. A full inbox gets ignored, and then the one email that mattered sits under forty that didn’t.
Why does your email address matter so much?
Because of how the CRA now sends mail. Online mail became the default way to deliver most business correspondence: new business registrations from 12 May 2025, and existing businesses from 16 June 2025. Your notices land in My Business Account instead of the post. The CRA tells businesses to add or update their email address there so they get a message when something new is waiting. Its online mail for business page also says correspondence is treated as received when it’s posted online, not when you happen to open it.
Miss that, and a notice can sit unopened while a deadline runs. Put a person on it who actually reads the inbox, not a shared address nobody checks.
Who tells you when accounting standards change?
Tax rules and accounting standards aren’t the same thing. The Accounting Standards Board sets accounting standards for Canadian private enterprises and publishes updates on its own website, including its review of the standards for private enterprises. We didn’t confirm a current change date, so check the board’s site or ask your accountant which standard your statements follow.
Most owners never need to read a standard. What you need to know is whether a change alters the statements your bank or investors see, and that’s a good question to ask your accountant at year end.
How to build a weekly routine that holds
Pick one slot. Twenty minutes every week comes to about 17 hours a year, which is a lot less painful than a panic in March. Use it to skim new emails, open anything about your industry or payroll and make a short list of anything that changes what you do. Friday morning with a coffee works for plenty of people.
Keep the list in one place. When a change affects your numbers, run them again. A new GST/HST or payroll rule might alter what you remit, and the payroll remittance calculator lets you test that, while the GST/HST calculator handles sales tax. A change in your profit can also move what you owe, and the tax installments calculator shows if your instalments still fit.
How do you tell a real change from noise?
Ask three questions of anything that lands in your inbox. Does it name a date or a rate? Does it apply to something you actually do, like running payroll or charging GST/HST? And is the source an official page, with a date you can check? If you can’t answer yes to at least two, file it and move on. Most headlines about tax changes are proposals, and a proposal isn’t law yet. Wait until the rule is announced as in force before you rebuild your books around it, and ask your accountant when the effect on your numbers is unclear.
What if you miss one?
It happens. Start with the CRA’s own newsroom pages and your My Business Account mail, not a forum post. A social media summary can be wrong, and old blog articles (including ones on this site) go stale. Check the date on any page before you rely on it, and look for the year.
One more habit helps. When you read about a change, write down what it affects and who handles it in the business. A change nobody owns doesn’t get acted on.
Our sources
The mailing list names and the online mail facts come from CRA pages on its electronic mailing lists and on online mail for business. The Accounting Standards Board description comes from its public information. The 17 hour figure is 20 minutes times 52 weeks. Nothing here tells you which change applies to you. This site is independent of the CRA and any government.
Frequently asked questions
Does the CRA still mail business notices?
Since May 2025 the CRA delivers most business correspondence online, in My Business Account. Add your email so you're told when mail arrives.
Which CRA list should an employer join?
The payroll list, which covers deductions, tax tables, taxable benefits, calculators and employment insurance information.
Who sets accounting standards in Canada?
The Accounting Standards Board sets them for private enterprises and publishes updates on its website. Check there or ask your accountant which standard you follow.
How often should I check for updates?
A fixed weekly slot works better than an occasional big read. Twenty minutes a week is about 17 hours a year.
Can I trust a blog post about a new rule?
Only if it names an official page and a date. Confirm on the CRA or the standard setter's own site.
