Hansa-Atlantic provides tax advisory services to entrepreneurs, companies and private individuals on almost all tax-related questions. International tax law is one of our main areas of expertise. For companies and entrepreneurs, the increasing globalization of their business activities poses special challenges concerning taxation. Effective tax structuring is required and double taxation to be avoided as far as possible. This requires specialist expertise and cross-border tax planning with foresight.

We furthermore focus on tax consultancy services required for national and international real estate investments (especially in the USA). We are specialized in the field of closed property funds and advise well-known initiators for more than 30 years. Please see below for more details in this respect.

We are acquainted with a number of tax consultants, auditors and lawyers who we can call on for any assistance needed. On an international level we have contact to tax consultants in many countries and employ their services for analyzing the tax impact of our clients’ cross-border activities, if necessary.

Hansa-Atlantic has been appointed as “Certifying Acceptance Agent“ by the Internal Revenue Service (IRS) and is authorized to obtain Individual Taxpayer Identification Numbers (ITIN) and Employer Identification Numbers (EIN) on behalf of limited partners of US Limited Partnerships as well as for any other non-US resident requiring an ITIN or EIN.
