Definition

The main place of business or employment, used to test whether someone is genuinely based abroad. It is distinct from residence and from domicile.

Why anyone asks

The United States taxes people rather than places, so a term defined here follows the passport. It is the single most common source of surprise in the files we take on.

The team at work in the open-plan office

The same word, two meanings

Cross-border files go wrong quietly here: one country has a concept the other does not, so a position that is obviously right domestically has no counterpart abroad. The mismatch is the exposure, and it is found by mapping the term in both systems rather than in one.

Where it shows up in practice

Tax home comes up in the pages below, which is usually a faster route than the definition itself — the term is only useful once you can see which filing it changes.

From term to filing

The question worth asking is not what Tax home means but whether it applies to you this year. That is a computation on your facts. Describe the situation in your own words; translating it into forms is our job.

The reason these entries carry no figures is deliberate. Thresholds move, and a definition is exactly the sort of text that gets quoted years later. So the mechanism is described here and the number is verified for your year when the file is prepared.

Cross-border situations we are engaged for

Case study 1

Establishing a tax home for a consultant working across several countries

The client's engagements ran concurrently in several places and no single one looked dominant. We built a workday record from invoices and calendars, identified where the practice was actually based between engagements, and tested each candidate location against the main place of business standard. One location carried the office, the records and the contracting party, and the position was written up on that basis. The engagement produced a documented tax home for the year, the workday schedule behind it, and a list of the facts that would have to change before the answer did.

Case study 2

A retained family home that put a tax home claim in doubt

A client working abroad on a rotation had kept the family house, and the family was living in it. The claim to be based abroad had been made without addressing that fact. We set out the working pattern, the assigned location under the contract, the accommodation abroad and the reason the house remained occupied, then reached a position on where the main place of employment actually was. The engagement produced a written analysis meeting the strongest contrary fact directly, and a recommendation on which arrangements would need to change for later years.

Case study 3

Tax home for an employee seconded part-way through the year

The secondment began mid-year, so the tax home was in one country for part of the year and arguably in another for the rest. We dated the change from the contract, the start of duties and the housing, then split the year at that point rather than forcing a single answer. Interaction with the residence position was handled separately so that the two were not conflated. The engagement produced a dated tax home position for each part of the year and a note of how the split fed into the filings on both sides.

Case study 4

Documenting a tax home after an enquiry questioned the claim

An enquiry letter challenged whether the client had been based abroad at all, and the original file held little beyond travel dates. We rebuilt the record from the employer, the foreign lease, client contracts and a reconstructed workday calendar, and answered the specific facts the letter raised rather than restating the claim. Where the evidence was weaker we said so. The engagement produced a documented response, the underlying records indexed to it, and a note of the one year where the position was not worth defending.

Case study 5

Separating tax home from residence for a client moving back

The client had returned home while continuing to run a business abroad, and had assumed the two questions moved together. They do not. We fixed the residence position on the ties, then examined separately where the main place of business had been over the same period, and found that the dates differed. The engagement produced two dated positions instead of one, filings that reflected the difference, and an explanation the client can give a future adviser without the analysis being derived again from scratch.

Case study 6

Tax home for a contractor with one foreign client and no office

A self-employed client billed a single client abroad and worked from whatever accommodation was available, with no premises of their own. The question was whether the client's premises, the accommodation, or nothing at all was the principal place of business. We examined where services were delivered, where equipment and records were kept, and what the contract required. The engagement produced a position supported by the contract and the delivery records, together with the practical steps that would put the following year on a firmer footing.

Case study 7

An Indian Company Paying a Foreign Supplier

Payments abroad carry deduction at source and a certification filed before the money moves. Whether the treaty reduces the rate depends on what is being bought, and the classification is the decision the whole filing rests on.

Case study 8

A Student or Researcher Covered by a Treaty Article

Several treaties carry a dedicated article for students, trainees and visiting researchers that displaces the ordinary employment rules. Whether it applies turns on the purpose of the stay and the source of the funds, both of which are evidenced rather than asserted.

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.

Cross-Border Real Estate

Foreign property income and sales are taxed in both countries by default; Section 216, FIRPTA and treaty credits are the standing toolkit.

Property is taxed where it sits, which is the one rule no treaty overrides. What the treaty does decide is the credit, the rate on the rent and what happens on the sale — and the clearance certificate on a disposition is applied for before closing, not after the buyer has already held the money back.

What people ask us about Tax home

What is my tax home if I work in two countries?

The tax home follows the main place of business or employment, so the answer comes from where the work is actually done rather than from where the contract was signed or the salary paid. Where duties are genuinely split, the question becomes which place is principal: where the workdays fall, where the employer expects the person to be, where the office or client base sits, and where the costs of working are incurred. If no location is principal, the claim to be based abroad becomes weak, and that has to be faced from the records rather than argued from the passport.

Can my tax home be somewhere I do not live?

Yes, and confusing the two is the most frequent error here. Residence asks which country may tax a person's income and on what basis. Domicile is a question of permanent attachment, used mainly in estate and succession work. Tax home asks something narrower: where the main place of business or employment is. A person can be resident in one country, domiciled in another and have a tax home in a third, and each answer is reached on its own facts. When somebody says their tax home is their house, they are usually answering a different question from the one asked.

Does keeping a house back home affect my tax home abroad?

It can, though not because a house is a tax home in itself. The purpose of the test is to see whether the person is genuinely based abroad, and a retained dwelling is evidence about where the base of living remains, particularly where the family is still in it, where trips back are frequent and long, and where the work abroad runs on a rotation. A property let out on ordinary commercial terms for a real term says something quite different from one kept available. Expect the house to be the first fact raised, and be ready to explain the working pattern alongside it.

Why does relief for working abroad depend on my tax home?

Because the relief is aimed at people whose working life has moved, not at people who have spent time away. The tax home test is the gate: it asks whether the main place of business or employment is outside the country, and the remaining conditions are only reached once it is satisfied. That is why a claim can fail on this point alone, with days abroad, a foreign lease and a foreign employer all in place. It is also why the test is worth settling before the year begins rather than at the point the return is being prepared.

Can someone who keeps moving between countries have a tax home?

Sometimes not, and that surprises people whose life has plainly left the country they came from. The test looks for a principal place of business or employment, and a pattern of short engagements in several places may produce none. The practical response is to look at what is actually stable: a base the person returns to between engagements, an office or registered place of business, the country the clients contract with, where equipment and records are kept. Where such a base exists the case can be made on those facts. Where none exists, the claim should not be made.

How do I evidence my tax home for a whole year?

With records made at the time that describe work rather than travel. Employment contracts and secondment letters showing where duties are to be performed, employer confirmation of the assigned location, a workday calendar, client contracts, invoices showing where services were delivered, the business premises or registration abroad, and the housing arrangements at both ends. A list of boarding passes answers a days question, not a tax home question. The file should be able to state in one sentence where the main place of work was, and then produce the documents that support the sentence.

Branch or subsidiary — which should we use to expand?

A branch keeps one taxpayer: results consolidate at home, losses are usable sooner, and the exposure is that the branch is a permanent establishment whose profit the host country taxes, sometimes with a branch tax on repatriation. A subsidiary is a separate taxpayer with limited liability and local rates, at the cost of withholding on dividends home and transfer pricing on everything between them. The deciding facts are usually expected losses, liability and exit plans. See branch against subsidiary.

Is "fund transfer pricing" the same thing as transfer pricing?

No — and if you came here to calculate FTP, this is not it. Fund transfer pricing is a bank's internal allocation of funding costs and benefits between its own business units, a treasury and asset-liability management discipline used to measure branch or product profitability. Tax transfer pricing is about prices between legally separate related parties across borders, and about which country taxes the resulting profit. The words overlap; the fields do not.
