What type of tax residency provider is this?
Greenback publishes a US expatriate tax practice. Residence work is the foreign-residence context for US filing: foreign earned income, the foreign tax credit and treaty interaction. It is a specialist filing and consultation practice, not a multi-country private-client residence firm.
Some providers primarily prepare returns; others handle complex multi-jurisdiction residence analysis. The distinction matters.
Who it may suit
Greenback Expat Tax Services may be relevant to US citizens and green-card holders living abroad.
Which countries can the provider coordinate?
Published global reach: High.
The published service is US-tax centric. Multi-country capability should be confirmed for the specific country combination. Published reach is not a list of offices or treaties.
Tax residency analysis
Residence is published in a US expat context: foreign residence as it affects US tax, the foreign earned income exclusion, the foreign tax credit and treaty interaction.
WiT Access does not determine whether you are tax resident in any jurisdiction.
Days and statutory tests
Day-count and statutory tests are published where they matter to the foreign earned income exclusion, bona fide residence and the local-country context of a US filing.
Counting conventions vary by jurisdiction.
Home, family, work and economic ties
Tie analysis is published as limited outside US-expat and local-country coordination.
Countries do not all use the same tie test. Home, family, work and economic connections may or may not be part of the local rule.
Treaty tie-breakers
Treaty work is published in a US treaty context. That does not mean every treaty is covered.
Not every treaty is identical. The applicable treaty text and protocol must be checked.
Planning before you arrive or leave
Pre-arrival and departure planning is published as strong for Americans moving abroad.
What if two countries treat you as resident?
Dual-residence work is published as US citizenship-based tax together with local residence considerations.
A treaty does not automatically remove filing in either country.
Tax returns and compliance
US expat tax preparation is the published core. Local-country filing is a separate question.
Tools and record keeping
Country tax guides and a remote tax workflow are published.
The WiT Access residency day tracker can help keep a record of days. A tracker helps preserve evidence. It does not determine tax residence.
How tax-residency advice is priced
Service pricing is published by the provider. No fee is repeated on this page. Request a written scope and fee quote.

Information is based on publicly available provider information reviewed by WiT Access. Tax-residence rules, treaty provisions, provider services and pricing can change.
WiT Access provides general information and comparison resources. Tax residence depends on domestic law, personal facts, treaty provisions and individual circumstances. Nothing on this page constitutes tax, legal, financial or investment advice.
WiT Access does not determine whether you are tax resident in any jurisdiction.
A residence permit, visa or citizenship does not by itself determine tax residence.
Day counting can be useful evidence but should not be treated as a substitute for professional analysis.
