 Trustindex verifies that the original source of the review is Google. Before engaging with SAL Accounting, sorting out payouts across Amazon and Shopify in different currencies literally used to eat up half of my week!!! That's like spending 6 months a year only on currency management. Bringing in SAL Accounting’s team was an absolute game-changer. They simplified our bookkeeping needs and showed us what our margins actually look like per channel. Thanks to SAL Accounting team!!

 Trustindex verifies that the original source of the review is Google. As someone who runs an Amazon store in the US while operating in Canada, I had several questions about bookkeeping, taxes, and how to keep my records organized. SAL Accounting’s team helped me understand the process and gave me clear direction on what needed to be done. The team was patient, approachable, and supportive, which made the experience much less overwhelming. I will be sure to book them for this and the upcoming years.

 Trustindex verifies that the original source of the review is Google. We have now been working with SAL Accounting for a few years & have been well looked after and very happy with the services Salman and his team provide. This tax season our cross-border returns were handled by AJ and he raised the bar with excellent service. AJ is  great. He not only has very good knowledge and experience, but also importantly so, he has such an excellent temperament. He is respectful, proactive, responsive, patient in that he takes time to explain things. I have really enjoyed working with AJ this year & trust both the filings done this year will be without any issue. We look forward to the years ahead.

 Trustindex verifies that the original source of the review is Google. I recently completed my first tax return season with SAL accounting. I’ve historically done my taxes myself, but this year was a particularly complex year for me considering I relocated internationally and hence had the complication of dealing with both US tax returns and Canadian tax returns. Being a sophisticated financial professional myself, I interviewed three firms before deciding that SAL accounting‘s professionals were knowledgable enough to handle my case. Over the course of my experience, I have only great things to say about the team at SAL accounting. Starting from the client support reps, they always helped me get access to the right professionals in a very timely manner and repeatedly followed up with me so I didn’t fall behind on my own schedule. I was paired with a tax expert that I thought was absolutely fantastic. He didn’t just do my returns but also helped me think through different tax strategies which was awesome. I found the expert to be top tier for three key reasons: 1) very client-centric (responding to my calls and emails same day); 2) super knowledgeable of the tax code of the US and Canada; 3) flexible and patient. I would recommend SAL accounting for anyone needing tax support.

Frequently Asked Questions

Questions answered by our cross-border accountants in Toronto.

How do you avoid double taxation between the US and Canada?

It depends. Canadian residents pay tax on worldwide income, and the IRS may tax your US income too. The US-Canada Tax Treaty prevents double taxation through foreign tax credits. A cross-border tax advisor helps you structure things right.

How can I avoid double taxation on foreign income in Canada?

Claim foreign tax credits for US taxes paid, use treaty elections, and structure your entities correctly. Smart Canada US tax planning with a cross border accountant ensures you keep more of what you earn.

What is the double tax treaty between Canada and the US?

An agreement that determines which country taxes what income and at what rate. It provides lower withholding rates, foreign tax credits, and permanent establishment rules. Proper Canada US tax compliance means using the treaty to your advantage.

What does a cross-border accountant do?

A cross-border accountant handles Canada US tax compliance in both countries: Form 1120-F for Canadian companies earning in the US, Form 1120 for US corporations, and treaty elections on Form 8833. They also help with entity structure and permanent establishment risks.

What is the 183-day rule for Canadians in the US?

If you’re in the US for 183+ days in a year (or hit the three-year formula), you could be seen as a US tax resident. This changes how your income is taxed and which treaty benefits apply. We provide international tax advice in Toronto to help business owners navigate this.

What is a permanent establishment under the US-Canada Tax Treaty?

A fixed place like an office, warehouse, or employees who regularly close deals in the other country. If your Canadian company has one in the US, those profits can be taxed by the IRS (even with the treaty).

What are the US-Canada tax treaty withholding rates?

Dividends are 5% (if you own 10%+ voting stock) or 15%. Interest is usually 0%. Royalties are mostly 0%. You only get these rates by filing the right forms. Good Canada US tax planning stops you from overpaying.

Do Canadian citizens need to comply with FATCA?

FATCA targets US citizens and residents, not Canadians directly. But if your Canadian business has US accounts or shareholders, banks may report under FATCA. US subsidiaries may require Form 5471 or 8865. Proper US tax preparation in Canada helps you avoid penalties.

What is the 90% rule for non-residents in Canada?

This rule allows non-residents to claim extra credits and deductions if 90%+ of their worldwide income comes from Canada. For US owners running Canadian operations, it can lower your Canadian tax bill. Our non resident tax advisor in downtown Toronto uses this for effective Canada US tax compliance.

My Canadian company has US clients. Do I need to file anything with the IRS?

If you earn US-source income, you may need Form 1120-F. Whether you owe tax depends on the treaty and permanent establishment status. Even if no tax is due, filing keeps deduction options open. Talk to a cross border tax accountant in Toronto for US tax preparation in Canada.

How much does a cross-border tax advisor charge?

Our fees are $3000 to $5000/month per entity. It depends on your situation and needs. Book a free call with our Canada US tax CPA for more information.

Is there a Canada-US cross border tax accountant near me?

SAL Accounting is based in Toronto, in the Financial District near Union Station, but our cross border bookkeeping and accounting experts work with businesses across Ontario online. We take care of your money remotely.
