Files that look like this one

Case study 1

A 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 runs
Case study 2

A Margin Defended With a Benchmarking Set That Fits the Facts

A comparables set is only as good as the screening behind it, and a rejected set takes the margin with it. The study selects the tested party first, screens on function rather than on industry code, and records why each comparable survived.

Case study 3

A Company Abroad Owned by a US Person

A business incorporated where the owner lives is a foreign corporation to the IRS, with a reporting package of its own and schedules that need local accounts restated. Classification comes first, because it decides what is reportable and when profits are taxed.

Read how this one runs
Case study 4

A Foreign Property Form Filed Late, With Penalties Running Daily

The foreign asset return carries a penalty that accrues per day rather than per return, so the exposure grows quietly. Relief is discretionary and it is granted on the reasons given, which means the request is the work rather than the form.

Read how this one runs
Case study 5

A US Citizen Settled in India, Filing on Both Sides

Residence in India and citizenship in the United States produce two annual returns for one income. The order decides the credit, and the Indian financial year and the US calendar year have to be reconciled before either is prepared.

Read how this one runs
Case study 6

The Same Income Taxed Twice on Paper

Relief usually exists and is lost to sequence: one country taxes at source and the other credits it, and preparing them in the wrong order claims a credit against a figure nobody has computed.

Read how this one runs
Case study 7

An Assignee Paid at Home and Taxable Away

Where pay stays on the home payroll but the tax arises elsewhere, a shadow run reports the second country's liability without duplicating the payment. Setting it up correctly is what keeps both sides reconcilable.

Read how this one runs
Case study 8

A Shareholder Loan Across a Border at No Interest

An interest-free loan between related companies is priced as if it carried interest, and in some cases a deemed benefit follows as well. The file sets a rate against the borrower's own credit profile and documents the terms that support it.

Core International & Cross-Border Tax Services

International Tax Planning & Advisory

Strategy and compliance for income, assets and families spread across borders.

One coordinating team: filings on every side of the border are sequenced so treaty relief and foreign tax credits are claimed once — and in the right country.

U.S. & Cross-Border Tax Returns

Dual filers: U.S. citizens in Canada and Canadians with U.S. income run two parallel systems — we prepare both, in the right order, every year.

Expat & Emigration Tax

The move year is its own project: the elections and valuations filed that year decide the next decade of both countries’ returns.

Non-Resident Canadian Tax

Default withholding is 25% of gross: elective returns routinely turn over-withheld rent and pensions into refunds.

Transfer Pricing & BEPS

Documentation prepared with the return is the cheapest insurance in international tax; reconstructing it during an audit is the most expensive.

Cross-Border Estates & Trusts

Wills drafted for one country routinely misfire in the other — deemed disposition here, estate tax there, credits in between.

Cross-Border Corporate Tax

Expansion raises the same four questions every time — entity, PE, repatriation, payroll. We answer them before the tax authorities do.

India Tax for NRIs & Returning Residents

The deduction is taken on the sale price, not the gain — which is why an NRI property sale strands cash unless the certificate is applied for before closing.

Canadian Tax with a Foreign Element

Residency is decided on facts, not on a form — and the year you arrive or leave is the one where the largest amounts turn on the smallest details.

UAE Tax for Expats & Their Home Country

A zero-tax country is only half the answer — the question that decides the bill is whether the country you came from still treats you as resident.

Professional Services Firms

Firms and partners working across borders meet Regulation 105 withholding, PE risk on long engagements and per-country payroll for travelling staff.

A partnership is taxed in the hands of its partners, so one engagement abroad can reach every partner's personal return. The order matters: the waiver is applied for before the invoice, the presence is tracked before it becomes an establishment, and the payroll is registered before the first day worked in the other country.
