If you live, work, invest, own a business, or hold assets on both sides of the Canada-US border, one tax return can affect the other.
Bestax helps individuals and businesses coordinate their Canadian and U.S. tax obligations so income is reported correctly and the same income is not taxed twice without available relief.

Our cross border tax services Canada are built for clients who have an active connection to both tax systems. We do not treat a cross-border file as two separate returns. We review how the Canadian and U.S. rules interact before the filing work starts.
If your issue is only a Canadian non-resident return with no active U.S. filing requirement, use our Non-Resident Tax Services page instead. If you only need the calculation of foreign tax credits, our Foreign Tax Credit Services page covers that work in detail.
A US Canada tax accountant is useful when the same income, asset, business, or residency question touches both countries. The issue is not always the amount of tax. The bigger risk is filing in one country without checking what the other country requires.
U.S. citizens and U.S. resident aliens are generally subject to U.S. tax rules on worldwide income even when they live abroad. A Canadian resident is also generally taxed in Canada on worldwide income. That creates a need to coordinate reporting, treaty positions, and available credits.
Bestax reviews your Canadian income and U.S. filing position together. We also identify foreign account and asset reporting that could apply, including FBAR and Form 8938 thresholds on the U.S. side.
Working for a U.S. employer or client can create filing, withholding, residency, and foreign tax credit questions. We review where the work was performed, your tax residence, the type of income, and taxes already withheld before deciding how the income should be reported.
U.S. dividends, interest, rental income, capital gains, and property sales can create reporting in both countries. Canadian residents must report foreign-source income in Canada. Certain U.S. filings or withholding rules can also apply depending on the asset and transaction.
A move can change tax residence, reporting periods, foreign asset treatment, and the way investment or business income is taxed. We review the move date, residential ties, immigration or citizenship status, and treaty residence rules before preparing the filing approach.
A Canadian business entering the United States needs more than a year-end tax return. We review the operating model, location of staff, contracts, related-party transactions, ownership structure, and whether activities create a taxable presence or other filing requirement.
Good cross border tax planning starts before the transaction happens. Fixing a filing after the fact is usually harder than choosing the right structure or reporting approach at the beginning.
The Canada-US tax treaty can affect residence, business profits, withholding, and double-tax relief. Treaty relief is not automatic in every situation. We review the facts and determine whether a treaty position is relevant and whether a disclosure or supporting filing is required.
This planning also focuses on timing. We compare the tax impact before a move, sale, distribution, bonus, business expansion, or major investment so you can make the decision with the tax result in view.
Our international tax services Canada focus on the Canadian reporting and planning issues that arise when your financial life extends outside Canada, especially into the United States.
Canadian residents generally report worldwide income. Separate information returns can also apply even where the income itself has already been reported on the tax return.
For a Canadian resident with U.S. assets, the T1135 threshold is based on cost amount, not current market value. The requirement is separate from the obligation to report foreign income. Bestax checks both so a client does not report the income but miss the information return.
This work also connects with our Transfer Pricing Services when related Canadian and U.S. companies transact with each other.
Our cross border tax compliance services are designed to bring the full file into one coordinated process.
We review your residential ties, travel dates, immigration status, citizenship or green card status, home, spouse or dependants, and other facts that affect tax residence. CRA residency is based on facts and significant residential ties. The Canada-US treaty also contains residence rules for dual-resident situations.
We identify which Canadian and U.S. returns or information filings are required for your facts. For individuals, this can include a Canadian T1 and a U.S. Form 1040 or another U.S. filing. For businesses, we review Canadian corporate obligations and the U.S. filing requirements created by the operating structure.
For Canadian residents, we check T1135 and other Canadian foreign reporting. For U.S. persons, we identify whether FBAR or Form 8938 reporting applies. FBAR generally applies when the aggregate value of foreign financial accounts exceeds USD $10,000 at any time during the calendar year.
The Canada-US treaty contains rules intended to reduce double taxation. We review which country has the primary taxing right, how income should be sourced, and what treaty relief is available for the specific income type.
For businesses, we assess the activities carried on in each country, related-party transactions, withholding exposure, and whether a permanent establishment or other filing obligation needs attention. Under the Canada-US treaty, business profits are generally taxable only in the residence country unless the business carries on business in the other country through a permanent establishment, subject to the treaty rules.
If a tax authority asks for more information, we organize the facts, returns, schedules, and supporting documents. We help you understand what the notice is asking and prepare a clear response within the scope of our engagement.
We also include a prior-year review where a client is unsure whether foreign income, foreign accounts, or required forms were missed.
Cross-border tax work becomes much easier when the facts are organized first. We start with a practical intake, not a long list of technical questions.
You do not need to decide which form applies before contacting us. Our team reviews the information and tells you what is relevant.

We start with the full Canada-US picture instead of looking at one return in isolation. This helps prevent inconsistent residency positions, duplicated income, missed foreign reporting, and avoidable follow-up work.
You receive a practical list of the returns, reporting forms, supporting documents, and planning issues that apply to your situation.
Cross-border issues often connect with corporate tax, bookkeeping, payroll, transfer pricing, or business setup. Bestax can connect those services without forcing you to explain the same business structure to several unrelated providers.
Bestax has a Canadian office at 1470 Hurontario St #100, Mississauga. You can work with us locally or remotely.
If your structure, residence, income, or business activity changes, we can review the tax effect before the next filing period. This is especially useful for clients who travel, invest, or operate businesses across the border every year.
For clients comparing Canada-US tax specialists, the goal should be more than completing two returns. The goal is to make sure both filings tell the same factual story and use the treaty and reporting rules correctly.
We collect your residency facts, citizenship or immigration status, income sources, foreign assets, business interests, and prior filings.
We identify the Canadian and U.S. returns, information forms, treaty questions, and deadlines that require attention.
We check income slips, statements, travel records, tax payments, ownership information, and prior assessments. Missing information is flagged before preparation moves forward.
We prepare or coordinate the required Canadian and U.S. tax work within the agreed scope. Income, taxes paid, residency positions, and foreign reporting are matched across the file.
We explain the key tax positions, filing obligations, and any items that need continued tracking. You know what is being filed and why.
We identify changes that should be reviewed before the next move, investment, distribution, corporate transaction, or filing year.

One of the best firm I have dealt with in Ontario. Bestax supported my corporate tax filing perfectly and even answered my silly questions without getting irritated. Love the personal touch they add to service.

It depends on your residence, citizenship or green card status, where the income was earned, and the type of income. U.S. citizens and resident aliens can have U.S. filing obligations on worldwide income even while living in Canada. Canadian residents generally report worldwide income in Canada. Bestax reviews both sides before confirming the filing list.
U.S. citizens are generally subject to U.S. tax filing rules on worldwide income. Living in Canada does not by itself remove that obligation. Treaty rules and foreign tax credits can reduce double taxation, but the filing requirement must still be reviewed.
The treaty contains rules for residence, income sourcing, business profits, withholding, and relief from double taxation. The result depends on the income and your facts. Bestax reviews the treaty position together with the domestic rules in both countries.
Canadian resident individuals, corporations, and certain trusts generally need Form T1135 if the total cost amount of specified foreign property exceeds CAD $100,000 at any time during the year. Certain partnerships can also have a filing requirement. The threshold is based on cost amount, not fair market value.
Not automatically. The total cost amount of all specified foreign property and the type of property matter. Some property is excluded. Bestax reviews the full asset list instead of looking at one account alone.
Yes. A U.S. person generally has to file an FBAR when the aggregate value of foreign financial accounts exceeds USD $10,000 at any time during the calendar year. Canadian bank and investment accounts can be foreign accounts for this U.S. reporting rule.
The answer depends on your residence, where the work is physically performed, payroll setup, and the treaty. We review the facts before deciding how the employment income and withholding should be handled.
Review your Canadian residential ties, investments, corporations, real estate, registered accounts, and planned transactions before the move date. Pre-move planning can identify departure-year reporting and cross-border issues before they become harder to fix.
Review the U.S. operating model, location of people and activities, contracts, related companies, withholding, state exposure, and whether the business has a taxable presence. On the Canadian side, foreign affiliate, non-arm's-length transaction, and transfer pricing reporting can also require attention.
Yes. We can review prior returns, identify what was missed, and explain the correction routes that fit the facts. The right approach depends on the form, year, tax authority, and reason for the omission.
