Specialized Knowledge

E‑Commerce Tax Expertise

Most accountants treat e-commerce revenue like any other business, but Amazon settlement reports, FBA fee structures, and multi-currency transactions require specialized knowledge to file correctly and minimize your tax burden.

We're sellers ourselves. We know the difference between a product sale and a shipping credit, and we know which expenses the CRA questions most. That means fewer mistakes, fewer audits, and more money in your pocket.

Proper treatment of FBA fees, PPC costs, and platform commissions
Inventory write-downs and obsolescence
Multi-currency USD/CAD conversion and reporting
Home office deductions for e-commerce operators
Inter-company transactions for multi-entity structures
Amazon, Shopify, and Walmart settlement reconciliation

How It Works

Six steps to a filed return

You send us your bookkeeping: you provide your books however they come (QuickBooks, Xero, spreadsheets). We also provide guides and walkthroughs showing you exactly how to pull the reports we need from your e-commerce platforms.
We review and identify issues: we go through everything, flag errors, missing transactions, and anything that doesn't add up. We reconcile your CRA accounts to make sure nothing has been missed.
We work through it together: we come back to you with questions and adjustments. No surprises at filing time.
We dig for deductions: we look for deductions you may have missed and make sure you're not leaving money on the table.
Filing: T2 filed with CRA, all schedules included, T4 and T5 slips prepared as needed.
Post-filing: we handle any CRA questions or notices on your behalf.

Frequently Asked Questions

Common questions about corporate tax

When is the corporate tax deadline?

Six months after your fiscal year-end for filing, two months after year-end for payment. If your corporation is eligible for the small business deduction, the payment deadline extends to three months.

Do you handle provincial tax too?

Yes. Federal and provincial corporate tax are filed together on the T2.

What do you need from me to get started?

Your bookkeeping files (QuickBooks, Xero, or spreadsheets) and access to your e-commerce platform reports. We provide step-by-step guides showing you exactly which reports to pull from Amazon, Shopify, or wherever you sell.

I'm behind on multiple years of corporate tax. Can you help?

Yes, we do multi-year catch-ups regularly. We'll work through each year methodically, reconcile your CRA account, and get you current. The sooner you start, the fewer penalties and interest charges accumulate.

I'm currently a sole proprietor. Should I incorporate?

It depends on your revenue, how much you reinvest vs. take home, and your long-term plans. Incorporation gives you access to the small business tax rate, income splitting through dividends, and liability protection. We'll review your numbers and tell you whether it makes sense now or if you should wait.

How long does the process take?

Typically 2-4 weeks from when we receive your bookkeeping to a filed return. It depends on how clean the books are and how quickly we can work through any questions together. Rush filings are available if you're up against a deadline.

Can you help restructure my business?

Yes. We advise on incorporation, holding companies, and entity structures to optimize your tax position.

When is my corporation's year-end?

Your fiscal year-end is set when you incorporate and is listed on your articles of incorporation. If you're not sure, we can look it up for you through your CRA account. Many e-commerce sellers choose a calendar year-end (December 31), but it can be any date.

I incorporated but never filed a tax return. What do I do?

This is more common than you'd think. Even if your corporation had no activity, the CRA still expects a T2 filing for every year since incorporation. We can sort out your year-end, file any outstanding returns, and get you back in good standing. The sooner you address it, the better, since penalties and interest keep accumulating.

Do you do bookkeeping too?

Yes. Many of our clients use us for both bookkeeping and tax. Having the same team handle both means fewer errors, faster turnaround, and no miscommunication between your bookkeeper and your accountant.
