CRA Updates May 2026: Drop Boxes Gone, New Audit Powers & What It Means for You

Lot going on with CRA this month. Drop boxes disappearing, new audit powers kicking in, a privacy report that should make everyone uncomfortable, and a major benefit swap coming in July. We've been fielding a ton of calls about these changes, so here's everything in one place.

If you run a business, are incorporated, or work for yourself — a few of these need your attention before the month's over.

1. CRA Drop Boxes Are Done

This has been coming for a while. CRA kept reducing drop box hours, closing locations, and nudging people online. Now they're making it official: all remaining drop boxes shut down permanently on May 29, 2026. Every tax services office and tax centre across Canada.

A lot of our older clients liked the drop boxes. Quick, no line, no stamps. That convenience is gone now.

So What Do You Do Instead?

• If you file on paper: You'll have to mail everything. Canada Post. Plan for delays — CRA processes paper returns slower than electronic ones anyway, and now add shipping time on top.
• If CRA asks for documents: Upload them through My Account or My Business Account. Or mail them. Those are your two options now.
• Honestly, just go electronic. NETFILE, EFILE through us, My Business Account — it's faster, you get confirmation, and you don't have to wonder if your envelope arrived.

2. Bill C-31 Gave CRA More Teeth — And They're Using Them

You may have heard about Bill C-31 in passing. Here's what it actually means for you: CRA can now go to your bank, your payment processor, even your business partners and demand records — and in a lot of cases, they don't need a court order to do it anymore.

What Changed

• They can go straight to third parties. Banks, Stripe, Square, your landlord — CRA can compel them to hand over your records with way fewer hoops to jump through.
• Penalties got steeper. If CRA sends you a letter asking for information and you don't respond in time? The fines escalate fast. We're talking compounding penalties.
• Reviews turn into audits quicker. The internal process for escalating a routine review into a full audit has been sped up. Less buffer time, fewer warning signs before things get serious.

Bottom line: if you get a letter from CRA, don't sit on it. Don't throw it in a pile. Respond — or have your accountant respond — within the timeframe they give you. This was always good advice. Now it's expensive advice to ignore.

3. The Privacy Report: 42,000+ Breaches Since 2020

This one's uncomfortable. The Privacy Commissioner investigated how CRA handles taxpayer data, and the report came back ugly: over 42,000 privacy breaches since 2020. That includes everything from sending someone's tax info to the wrong address, to CRA employees accessing accounts they had no business looking at.

The Commissioner gave CRA nine recommendations. CRA accepted all of them and said they'd fix things, but the timeline is vague and nobody's holding their breath.

What You Should Actually Do

• Log into My Account and My Business Account. Check your address, your direct deposit info, your authorized representatives. Make sure nothing's been changed without you knowing.
• Turn on multi-factor authentication. Seriously. If you haven't done this yet, do it today. It takes two minutes and it's the single best thing you can do to protect your account.
• If something looks off, report it. Got a letter that doesn't match your records? A notice about a change you didn't make? Call CRA right away, and let your accountant know.

4. CRA Reviews Can Now Come Any Time of Year

Used to be, most CRA reviews happened between April and August. You'd file your return, maybe get a review letter in the summer, deal with it, and move on. Predictable.

Not anymore. CRA is now running post-assessment reviews year-round. You could get a review letter in November. In February. Whenever. They say it's to reduce backlogs, which is probably true, but it also means you can't let your guard down after tax season ends.

What This Means Day-to-Day

• Don't bury your tax stuff after filing. That shoebox of receipts? Don't put it in the basement in June. A review letter could show up in December asking for those exact documents.
• Set up email alerts in My Account. CRA will notify you when new correspondence arrives. Way better than finding out three weeks later when you finally check the mailbox.
• Keep us in the loop. If a review letter shows up in October, you need help just as much as you would in May. Don't try to handle it yourself just because it's "off-season."

5. 2026 Numbers You Should Know

Quick reference for the stuff that comes up in almost every client conversation. Bookmark this one:

6. Say Goodbye to the GST/HST Credit

The GST/HST credit has been around forever. Everyone knows it. Starting July 2026, it's being replaced by something called the Canada Groceries and Essentials Benefit.

Same idea — quarterly payments to help with cost of living — but the amounts and income cutoffs are different. The government says the transition will be automatic for current recipients, but "automatic" and "smooth" aren't always the same thing with CRA.

The Short Version

• You don't need to apply. If you're getting the GST/HST credit now, you should get the new one automatically.
• The amounts will be different. Could be more, could be less, depends on your income. Check My Account after July to see what you're getting.
• Quarterly schedule should stay the same. But CRA hasn't confirmed exact dates yet, so keep an eye out.

7. T4A Crackdown Starting with Trucking

If you're in trucking or you hire trucking subcontractors, pay attention. CRA has made the transportation industry its first enforcement target for T4A compliance. Starting with 2025 tax year filings (the ones being processed right now), they're cross-referencing subcontractor income against T4A slips — and if the numbers don't match, expect a call.

This isn't just a trucking thing, by the way. CRA picked trucking first because the gap between reported income and actual payments is historically wide in that sector. But they've made it clear other industries are next. If you pay subcontractors in any industry, take this seriously.

If You Pay Subcontractors

• T4A slips for every subcontractor you paid more than $500 in the year
• T4A summaries filed with CRA by end of February
• Keep your subcontractor agreements, invoices, and payment records organized
• Missed 2025? File them late. A late-filing penalty is way cheaper than a non-filing penalty

8. CRA Is Using AI Now (But Don't Panic)

CRA disclosed that they're running 19 AI systems internally. Sounds dramatic, but what they're actually doing with them is pretty mundane: flagging returns that look unusual, prioritizing which files to review, and detecting potential fraud patterns.

They've been clear that no AI is making final decisions on anyone's taxes. A human still reviews your file and signs off on any reassessment. But here's the thing — the AI is deciding which returns get looked at. And it's looking at way more data points than a person ever could.

9. What to Do This Month

Here's the short version. Eight things to check off before June:

1. Go electronic if you're still on paper — drop boxes are gone May 29
2. Check your CRA accounts (My Account + My Business Account) — make sure nothing's been changed without your knowledge
3. Turn on multi-factor authentication — 42,000 breaches is a lot of breaches
4. Keep your records handy — CRA reviews can come any time now, not just summer
5. Sort out your T4As if you pay subcontractors — trucking is first, but every industry is on the list
6. Know your RRSP room — $33,810 for 2026, and unused room carries forward
7. Watch for GST/HST credit changes — the switch to Canada Groceries and Essentials Benefit happens in July
8. Answer CRA letters fast — the penalties for ignoring them just got worse
