What type of international tax provider is this?
Andersen publishes international tax advisory for private clients and businesses, covering cross-border personal tax, corporate international tax, trusts, structures, repatriation and treaty issues. The model is a professional advisory and member-firm network. It is not a simple compliance shop, and network reach does not mean every office covers every issue.
Large global networks may coordinate multiple countries, while specialist firms may provide deeper expertise for particular client types or country combinations.
Who it may suit
Andersen may be relevant to HNW individuals, family offices, entrepreneurs and international businesses.
Which countries can the provider coordinate?
Published global reach: Very high.
Published reach is very high. Multi-jurisdiction capability should be confirmed with the relevant country teams before engaging. Published reach is not a list of offices or treaties.
Personal international tax
Personal cross-border tax is published as exceptional, within private-client international tax.
Business and corporate international tax
Corporate international tax is published as exceptional, including international businesses and private businesses.
Trusts, estates and private-client structures
Trusts are published as a strong part of the private-client and structuring work. That is not a statement about a particular trust or estate.
Planning before a move
Pre-move and pre-immigration planning is published as strong.
Tax residency
Tax residency work is published as strong. Residence remains a legal and factual question for the relevant countries.
Tax residence is fact-specific and should be determined by a suitably qualified adviser.
Treaty and double-tax relief
Treaty and double-tax relief work is published as exceptional. That is not a conclusion on any particular treaty.
A treaty may allocate taxing rights or provide relief. It does not automatically remove filing or reporting obligations.
Tax returns and compliance
Tax compliance is published as strong, alongside the advisory work. Filing still depends on the jurisdictions in the engagement.
How the service is delivered
The published model is professional advisory through a member-firm network.
How fees are structured
Fees are engagement-specific. No public fee schedule is repeated here. Request a written scope and fee quote.
