Secure tax filing in Canada: How H&R Block protects your data against new cyber threats in 2026.

Let’s be real: tax season usually comes with enough "fun" surprises – like realizing the crucial receipt you need is currently acting as a bookmark in a half-finished novel. But in 2026, the question isn’t just about how much you’re getting back; it’s about making sure your data doesn't go on a vacation without you.

That’s why at H&R Block; we’ve done the heavy lifting for you. We use a combination of advanced security controls, including encryption, multi‑factor authentication, 24/7 cyber defense monitoring, secure document handling, and ongoing cybersecurity training for Associates – all designed to help safeguard client information.

The 2026 fraud landscape: more than just "bad emails".

Across the globe, we’re seeing a shift from simple impersonation to complex cyber-tactics. Scammers are using AI to mimic official government voices and creating realistic "ghost texts" that look exactly like a Canada Carbon Rebate notification. Their goal? To trick you into "push fraud" – willingly sharing your sensitive info or sending money to a "legitimate" looking source. (The CRA’s official website has more tips on how to recognize a scam). 

Protecting your banking details, Social Insurance Number (SIN), and government IDs is the core of a successful tax season and protecting yourself against identity theft. So, what does that have to do with where you file? Everything.

Our security protocols: The H&R Block "Shield".

When choosing where to file your taxes, ensure your tax preparer is committed to protecting your data, and has the tools required to do it well. Here’s a look at some of the cybersecurity measures we have in place to keep your information safe:

1. Mandatory Multi-Factor Authentication (MFA).

You’ve likely used this for your bank: it’s the digital equivalent of a second lock on your front door. By requiring a password plus a secondary code on all our internal systems and client platforms, we ensure that even if someone guesses a password, they still can't get your personal information. Think of this as a way to prove it’s really you, twice.

2. 24/7/365 cyber defense monitoring.

Fraudsters don’t take the weekends off, and neither do we. Our dedicated security teams leverage "always-on" monitoring to flag suspicious activity in real time. If something looks off, we’re already on it.

3. Advanced email protection & encryption.

Sending tax slips via a standard email is a bit like sending your diary on a postcard – it’s something you should never do. Our systems use best-in-class encryption to protect your documents. We even restrict certain data from being sent by email, at all, keeping your private information out of the digital "lost and found."

4. Cybersecurity-certified Tax Pros.

It’s not just about tech; it’s about the people. Every H&R Block Associate undergoes mandatory, ongoing cybersecurity training to spot the latest threats before they ever reach your file.

5. Secure handling & storage.

Your data is stored securely with strict handling protocols, safeguarded by our cybersecurity team. We manage your information with the same care we’d use for our own.

File with confidence, not concern.

Whether you’re visiting an office near you or filing from your couch, you’re covered when using our secure online software. We aren't just here to find every credit and deduction you're entitled to, we’re here to make sure your information stays safe, as well. 

Frequently asked questions: Secure tax filing in Canada.

How can I tell if a tax filing service is secure?

A secure tax filing service should use multiple layers of protection, such as encryption, multi‑factor authentication (MFA), secure document handling, and active fraud monitoring. It’s also important that Tax Professionals receive regular cybersecurity training and that sensitive information is stored and shared securely, not through standard email.

Is it safe to file my taxes online in Canada?

Yes, when you use a reputable tax service with strong cybersecurity controls. Secure online tax filing platforms use encryption, authentication safeguards, and monitored systems to protect personal and financial data from unauthorized access.

What personal information is most at-risk during tax season?

During tax season, scammers often target information such as your Social Insurance Number (SIN), banking details, tax slips, and government IDs. Protecting this information is essential to reducing the risk of identity theft and fraud.

What are “ghost text” scams and how do they work?

Ghost text scams are fraudulent SMS messages designed to look like legitimate government or financial notifications, such as benefit payments or rebates. These messages often include links that lead to fake websites or prompt users to share sensitive information.

How does multi‑factor authentication (MFA) help protect my tax information?

Multi‑factor authentication adds an extra layer of security by requiring more than just a password to access an account. Even if a password is compromised, MFA helps prevent unauthorized access to your personal tax information.

Can my tax documents be sent securely by email?

Standard email is not the safest way to share sensitive documents. Secure tax services use encrypted communication methods and may restrict certain personal or financial information from being sent by email altogether to reduce the risk of data exposure.

What is “push fraud” and why is it a risk during tax season?

Push fraud occurs when scammers impersonate trusted organizations and manipulate individuals into willingly sending money or sharing sensitive information. During tax season, fraudsters may pose as government agencies or tax service providers to appear legitimate.

How does H&R Block Canada protect my personal tax data?

H&R Block Canada uses a combination of advanced security controls, including encryption, multi‑factor authentication, 24/7 cyber defense monitoring, secure document handling, and ongoing cybersecurity training for Associates – all designed to help safeguard client information.

Is my information protected whether I file in person or online?

Yes. H&R Block applies security protocols across all filing options, whether you visit an office, work remotely with a Tax Pro, or use secure online tax software.

What should I do if I receive a suspicious CRA‑related message?

If you receive a suspicious call, email, or text claiming to be from the CRA, do not click links or share personal information. Instead, visit the CRA’s official website to verify communications and review current scam alerts.

Why does cybersecurity matter when choosing where to file my taxes?

Filing taxes requires sharing some of your most sensitive personal and financial information. Choosing a tax service with strong cybersecurity practices helps reduce the risk of fraud, identity theft, and unauthorized access to your data.

Can tax fraud impact my refund or benefits?

Yes. If your personal information is compromised, fraudsters may attempt to file false returns or redirect refunds and benefits, potentially delaying or preventing you from receiving money you’re entitled to.
