ToggleRunning a business often brings a variety of bills, forms, and numbers to track. Among these, GST and HST can feel challenging. Over time, the CRA has moved many filings online, and for some businesses, Mandatory Electronic Filing may no longer be optional. It would become the only way you have to submit returns, rather than a choice.
Small-business owners might not fully understand what this means. How it works, who it affects, and what might happen if it is ignored may seem unclear. This blog walks through the rules, who it can affect, why it might matter, and how businesses can adjust without stress.
Mandatory Electronic Filing means some businesses must file GST/HST returns online. Paper forms may no longer be enough in certain cases. Instead, submissions often go through CRA’s web portal or certified software.
This is not just a suggestion. CRA may see it as a way to modernize filings, reduce errors, and speed up processing. Businesses that meet certain thresholds may have to use online systems every time they file. Filing by paper, even occasionally, could be disallowed for these businesses.
Not all businesses are forced to go online. CRA sets criteria that determine who falls under the rule. Some common factors include:
Businesses with larger sales or revenue totals may cross the threshold that triggers online filing.
Those registered for GST or HST and filing regularly—monthly, quarterly, or annually—may need to comply.
Corporations, partnerships, and trusts could have different requirements applied by CRA.
Companies already using CRA portals for payroll or corporate tax may also need to file GST/HST online.
Because rules can change, checking with CRA or a tax professional may help businesses avoid surprises.
Mandatory Electronic Filing is introduced to make things easier for Canadian businesses:
Submitting online may reach CRA instantly. Refunds, credits, or assessments could happen sooner than expected.
Digital systems often catch missing fields or simple miscalculations. Mistakes that happen on paper forms may happen less frequently online.
Printing, mailing, and manual entry may shrink. Some businesses may even save money despite software fees.
Encrypted systems may protect sensitive data better than paper stored in an office.
Digital storage can make past returns easy to find. Businesses may audit themselves without digging through piles of paper.
Less paper means less waste. Filing online can align with eco-conscious practices.
CRA may roll out the mandate in stages rather than all at once.
Businesses may get warnings, guidelines, or windows to adjust.
Once active for a group, businesses meeting criteria may have to submit returns online by the cutoff date.
After the initial switch, online filing may be expected for every period without exception.
Staying aware of CRA announcements can help avoid last-minute surprises.
Sign up for CRA’s My Business Account or a similar portal. This gives access to tools needed for filing.
You can use CRA’s web forms or certified accounting software.
Collect sales, input tax credits, and adjustments like you would for paper forms.
Systems may highlight mistakes or missing numbers. Reviewing them before submission can save headaches.

Send the return through the portal or software.
Keep the reference or confirmation number. It may help if CRA ever asks.
If GST/HST is owed, pay online through CRA My Payment, pre-authorized debit, or banking portals.
Store digital copies safely for audits or internal checks.
While online filing brings benefits, some businesses may face obstacles:
Not everyone may know how to use the software or portal.
Certified tools may feel expensive, especially for micro-businesses.
Poor connectivity can delay submissions or frustrate users.
Time may be needed to understand the platform or software.
Some firms worry about hacking or data loss.
If CRA or software servers are down, timely filing may be difficult.
Register and try the system well before deadlines.
Ensure the person handling taxes understands the tools.
Stick to CRA-approved tools to avoid errors.
Check for mistakes using system features.
Store digital copies on secure drives or cloud storage.
Rules may change; staying informed can prevent trouble.
A mobile hotspot or alternate internet may help during outages.
Strong passwords, two-factor authentication, and encryption may reduce risk.
Tools like CRA My Payment or pre-authorized debit may prevent missed deadlines.
Ignoring mandatory electronic filing may bring problems:
CRA may penalize late or incorrect submissions.
Unpaid GST/HST may grow over time.
Non-compliance could raise CRA scrutiny.
Delays in processing can affect cash flow or refunds.
Partners, suppliers, or investors may view repeated non-compliance negatively.
The direct approach: file through My Business Account.
QuickBooks, Sage, Xero, and similar tools allow preparation and submission.
Specialized services may focus solely on online filings.
Larger companies may use enterprise systems for tax reporting and compliance.
Choosing a tool that matches your business size and CRA requirements may save frustration.
Mandatory electronic filing is no longer optional for some businesses. It can be faster, more accurate, and less stressful than paper submissions.
