What type of tax provider is this?
Greenback publishes US expatriate tax preparation for US citizens and green-card holders living abroad. The model is a specialist filing and consultation practice. It is not a global multi-jurisdiction advisory firm.
Provider size and brand do not by themselves determine whether the relevant local tax team covers your particular issue.
Who may find this service relevant?
Greenback Expat Tax Services may be relevant to US citizens and green-card holders living abroad.
Which jurisdictions can the provider coordinate?
Published global reach: High.
The published service is US-tax centric. Multi-jurisdiction capability should be confirmed for the specific countries and the engagement team. Published reach is not a list of offices or treaties.
Personal cross-border tax
Personal US expat tax is the published core, including preparation, consultations and country-specific tax guidance in that US context.
Business and corporate tax
Business tax is published only in a limited US expat context. This is not a general international corporate practice.
Tax residence
Residence is discussed where it affects foreign tax and treaty interaction for a US expat. This is not a general domestic-residence practice for every country.
Tax residence is a legal and factual determination. WiT Access does not determine a user’s tax residence.
Double-tax treaties
Treaty work is published in a US treaty and foreign-tax-credit context. That does not mean every treaty, or every article of a treaty, is covered.
A treaty usually allocates taxing rights or provides a route to relief. It does not, by itself, mean there is no tax and no filing.
Planning before you move or restructure
Cross-border planning is published as strong for US expats. It is planning inside that US filing context.
Tax returns and compliance
US expat tax preparation, FBAR/FATCA and streamlined filings are the published core. Filing in the country of residence is a separate question.
A provider that prepares returns may not also provide complex planning. Check who advises, who files, and which jurisdictions they cover.
How the service is delivered
A secure online portal and a remote tax workflow are published.
How fees are structured
Service pricing and fee schedules are published by the provider. No fee is repeated on this page. Request a written scope and fee quote.
