US Tax CIS

your US tax team

About us

We are a trusted US tax advisory firm specializing in complex individual and cross-border tax matters. We help clients navigate reporting obligations, evaluate planning opportunities, and manage the tax implications of important personal and financial decisions.

Drawing on more than 25 years of experience and Big Four backgrounds, we have developed extensive expertise in multi-jurisdictional tax matters, international ownership structures, relocation planning, wealth transfers, and cross-border reporting. Our partners hold CPA and Enrolled Agent (EA) credentials and combine deep technical knowledge with extensive practical experience.

We view our role as more than assisting with a single project or compliance obligation. We build lasting relationships with our clients and support them throughout the lifecycle of their investments, businesses, relocation plans, and family wealth structures. By acting as a central point of coordination and working closely with legal, tax, fiduciary, and other advisers across jurisdictions, we help address complex international matters through solutions tailored to each client’s specific circumstances and long-term objectives.

How we can help

US Tax Matters We Can Assist With

US tax obligations may arise in more situations than many people expect. If you live in the United States, hold a green card or US passport, or have income, assets, or business interests connected with the US, we can help you understand what may need to be filed or reported and what should be planned in advance.

The examples below show common situations where we help clients understand the applicable US tax rules and determine the practical next steps.

01

You need to prepare and file your US tax returns

We help you understand what needs to be filed and prepare the relevant US tax returns, disclosures, and international reporting forms.

02

You have foreign accounts, assets, or a business outside the United States

If you hold foreign bank accounts, investments, companies, partnerships, trusts, or other assets outside the United States, we help identify what should be reported in the US and prepare the necessary forms and disclosures.

03

You are moving to or from the United States

We advise on how moving to or from the United States may affect your taxes, what should be planned before the move, and what steps may be needed if you are giving up US tax residency.

04

You are not a US citizen or resident, but have income, assets, or investments connected with the United States

We help you understand when US tax rules may apply to your US-source income, US real estate, bank or brokerage accounts, investments through LLCs, partnerships, foundations, and other US-connected structures.

05

You received an inheritance or gift, or are planning to transfer assets

We advise on the tax and reporting implications of gifts, inheritance, and family wealth transfers, including cross-border situations, and assist with the preparation of the required tax filings and disclosures.

06

You are thinking about setting up a trust, a family holding structure, or another long-term way to hold your assets

We help evaluate available structuring options, explain the tax implications of trusts and other holding vehicles, and design structures aligned with your family, succession, asset protection, and tax planning objectives.

07

You need to correct prior tax filings or catch up on missed reporting

We assist with amended returns, previously unfiled tax returns, and available disclosure procedures designed to restore compliance with US tax requirements.

08

You received a notice or inquiry from the IRS or a state tax authority

We help assess the issue, prepare responses and supporting documentation, and assist with communications with the relevant tax authorities.

09

You worked for a US company or received stock options or equity compensation

We advise on the US tax treatment of employment income, stock options, restricted stock, and other equity compensation, including situations where you live or work outside the United States.

10

Your child was born in the United States or holds a US passport, and you are unsure what this means for your family

We help you understand potential US tax filing and reporting obligations, even if the child lives outside the United States.
