Cross-border situations we are engaged for
A Canadian Working in the US on a Work Visa
Immigration status and tax residence are different tests, and a visa says nothing about which country taxes the salary. The file fixes residence, applies the employment article, and sequences the two returns so the credit lands where it is usable.
Read how this one runsNever Filed a US Return — and Only Just Found Out
Born in the United States, left as an infant, and told by a bank that the returns were owed all along. The work is sequencing: establish which years are actually open, choose the catch-up route on the facts rather than filing quietly, and claim the exclusions and credits that were never taken.
Read how this one runsA Family Trust Abroad With Reporting on Both Sides
A trust settled in one country and a beneficiary living in another produces reporting for the trust, the settlor and the beneficiary, on different forms and different dates. The engagement maps who files what before anything is prepared.
Read how this one runsA US LLC Owned From Canada
The two countries classify the vehicle differently, so relief that ought to apply frequently does not and the same profit can be taxed in both hands. The engagement examines whether the structure can be changed and what the change itself costs.
Read how this one runsA US Filer Married to Someone Outside the System
Electing to treat a non-resident spouse as a US filer buys joint rates and brings that spouse's worldwide income and foreign accounts into the return. The election is easy to make and hard to revoke, so both positions are modelled first.
Read how this one runsTreaty Relief Claimed on a Cross-Border Estate
The estate article can extend a proportionate credit where the two systems would otherwise both tax the same asset. Claiming it requires a valuation and a disclosure the estate may not expect to make.
Read how this one runsA Penalty Argued on the Facts Rather Than the Form
Reasonable cause is a documented story with dates, not an assertion of good intent. The engagement assembles what the client actually knew and when, and puts the sequence in writing alongside the filings it explains.
Read how this one runsA US LLC Owned by a Canadian, Taxed Twice by Design
The two countries classify an LLC differently, so the credit relief that ought to apply frequently does not. The engagement looks at whether the structure can be changed, and where it cannot, at how to make the credit work.

Global E-commerce & Marketplaces
Cross-border tax for sellers shipping worldwide: marketplace withholding, foreign registrations and inventory nexus handled before they become audits.
Marketplaces withhold, remit and report in their own right, so the tax position of a single sale is decided by where the stock sat, where the buyer was and which platform collected — not by where the company is registered. We reconcile the platform's own filings against the returns before either is submitted.
