Tax return preparation

We offer personal resident and non-resident tax return preparation services for Luxembourg, the UK and the US.

For individuals with multi-country requirements, using the same team for your tax compliance obligations in each country ensures a consistent approach to reporting, optimises taxes and increases efficiencies by reducing the time that you have to spend gathering data.


In Luxembourg, we can assess and advise on the various filing options available to you (particularly in the year of transfer to/from Luxembourg) to determine the best filing option. For cross-border workers we can analyse your situation to determine the most beneficial position. For non-residents, we also offer a proxy service where all correspondence can be sent to us at a Luxembourg address and we then liaise with you regarding any actions required.

If you are a US citizen or greencard holder, you most likely have a US federal income tax filing obligation regardless of where you are living.

We can prepare Federal and State returns as well as file extensions (with or without calculations), calculate quarterly estimated payments, prepare forms reporting foreign bank accounts and financial assets and advise on foreign earned income exclusion and foreign tax credit claims.

Using in-house accounting expertise we are able to prepare the full suite of foreign corporation information returns including Form 5471 (Information Return of U.S. Persons With Respect to Certain Foreign Corporations) and Form 8858 (Information Return of U.S. Persons With Respect To Foreign Disregarded Entities).
