April is here! Most individuals need to file their personal tax returns by April 30th. If you haven’t put your tax slips together already, now is the time to do it!

Welcome to busy season. While you’re managing Spring sales and preparing for Summer, there’s a date you cannot afford to miss: April 30.

For business owners operating as sole proprietors, this month brings a critical deadline that often gets misunderstood. Let’s clear the confusion and protect your cash flow.


The Payment vs. Filing Trap

This is the number one mistake we see sole proprietors make. The rule is simple: if you owe personal taxes for 2025, the CRA starts charging interest on May 1, 2026.

The Reality: “I’m self-employed, so I have until June 15 to file.”

The Trap: Yes, you can file in June, but you must pay by April 30.

Action Item: If you need more time to get your papers ready, let’s estimate your tax bill now. Making a payment by April 30 — even an estimate — stops the interest clock.


Cash Flow Crunch: Inventory vs. Taxes

April is tough on cash flow. You might be buying inventory for Summer and Prime Day at the exact moment your tax bill is due. Here’s a strategy most founders overlook: don’t drain your operating account to zero to pay the CRA.

If cash is tight to pay taxes, you can explore setting up a payment plan with CRA, or another form of credit — both of which have lower interest rates than the high-interest merchant cash advances from platforms like Shopify Capital or Stripe. Make sure to review rates!


Digital Services Tax Radar

The global tax landscape is shifting beneath your feet. If you’re selling digital products — courses, downloads, software — internationally, many jurisdictions now require you to collect VAT and sales tax even if you have no physical presence there.

Pro Tip: Check your “Tax Settings” in your eCommerce platform. Are you automatically collecting tax for customers in the EU or UK? If not, you might be liable for it out of pocket.
