April 30 Tax Deadline: A Last-Minute Checklist for Vancouver Business Owners
You’ve been meaning to deal with this for weeks. Maybe months. And now the April 30 tax deadline is 15 days away and you’re wondering what exactly is due — and whether you’re already behind.
Here’s your checklist. No fluff, no lecture. Just what you need to know and do.
What’s actually due on April 30
This is where it gets confusing, because April 30 isn’t one deadline — it’s several.
Your personal income tax return. Even if you pay yourself through your corporation, you still file a personal return. Any salary, dividends, or other income you pulled from the business in 2025 gets reported here. Filing and payment are both due April 30.
Corporate tax balance owing. If your corporation has a December 31 year-end, your tax payment was technically due two to three months after year-end — but any remaining balance owing accrues interest. If you haven’t settled up yet, do it now.
GST/HST quarterly return. If your business is on quarterly filing, your Q1 return (January to March 2026) is due April 30. If you collected GST, this is when you remit it.
So if you’re an incorporated business owner who takes a salary and is registered for GST, that’s multiple obligations landing on the same day.
The payment-before-filing trap
This one catches a lot of business owners who are also self-employed on the side — or whose spouses are.
If anyone on your return has self-employment income, the filing deadline extends to June 15. But the payment deadline is still April 30. CRA starts charging interest on May 1 regardless of when your return is due.
So if you wait until June to figure out what you owe, you’ve already been accumulating interest for six weeks. And if you owe a meaningful amount, that adds up fast.
The fix is simple — estimate what you owe and pay by April 30, even if you file later.
Your last-minute gathering checklist
You probably have most of this already. Here’s what to pull together:
T4 and T5 slips from your corporation — salary and dividend slips your company issued to you
T4As — if you received any contract income outside your corporation
Shareholder loan balance — if you’ve been pulling money from the corp outside of payroll or dividends, your accountant needs to know
Business income and expense summary — your P&L for the year. If your books are up to date, this is easy. If they’re not, this is where the scramble starts.
Vehicle log — if you claim business use of a personal vehicle, CRA wants a logbook
GST collected and paid — for your Q1 return
RRSP contribution receipts — contributions made by March 1, 2026 count for the 2025 tax year
Previous year’s notice of assessment — your accountant will want this for reference
Corporate financial statements — if your T2 is still in progress, at minimum get your accountant the year-end trial balance
If you’re missing something on this list, don’t let that stop you from filing what you can. A late return with a balance owing is worse than an on-time return that gets amended later.
Common mistakes to avoid
Forgetting the GST Q1 return. It’s easy to focus on income tax and forget that your quarterly GST is due the same day. Late GST remittances come with their own penalties.
Not reconciling your shareholder loan. If you’ve been taking draws from the corporation without running them through payroll or declaring dividends, that’s a shareholder loan — and CRA has rules about how long you can carry it. Your accountant should be looking at this.
Leaving deductions on the table. When you’re rushing, you miss things — home office, vehicle, professional development, software subscriptions. These are real dollars.
Not planning instalments for next year. If your corporation or you personally owe more than $3,000 in net tax, CRA will expect quarterly instalments going forward. Get ahead of this now so next April isn’t a repeat.
Next year doesn’t have to feel like this
So here’s the honest version of what’s happening right now: you’re trying to reconstruct a year’s worth of financial information in two weeks. That’s stressful, and it usually means you’re paying more in accounting fees, missing deductions, and making decisions under pressure.
Year-round bookkeeping eliminates the April scramble. When your books are current and your month-end close is happening on schedule, tax season is just a filing — not a project.
If you’re staring down April 30 and want help getting it sorted — or if you’re ready to make sure next year is different — let’s talk. No pressure, just a conversation about where you are and what would actually help.
