What the work is worth.

One founder in the US, one group in Europe.

1.8USD m

less tax on a single disposal

A founder's share sale, taxed once instead of twice

A secondary sale was in motion while the founder was moving between two countries. Both could claim the gain. We re-sequenced the move and the shareholding before anything was signed.

Europe · Business

46%less tax, every year

EUR 2.4m a year

A three-country software group, from 26% to 14%

The group's IP sat in a holding company with no people behind it. We moved it to where the team works, added real substance, and documented the whole thing to file.

Why not a Big Four firm, or a platform?

The biggest savings sit where your personal and company tax meet. We plan both as one.

One team for you and for your company.

You and your company

A group structure that lowers the company's rate can cost you your residency. We plan the two positions together, under one lead, so neither undoes the other.

One lead for both positions
One plan, sequenced across both
One calendar of filings and renewals

Questions people ask before booking.

Book a free consultation

Free, 30 minutes, by video or phone. Every request answered within 24 hours.

Is this legal?

Yes. Everything we do is tax planning within the rules: real residency, real substance, documented transfer pricing and positions filed openly with the authorities. If a structure only works while nobody looks at it, we won't build it.

What happens in the free consultation?

Thirty minutes by video or phone. You tell us where you, your family and your companies sit today and what decision is coming up. We tell you honestly whether there is something to gain and what the next step would be. There is no obligation.

What does "available 24/7" actually mean?

Once you are a client you have a dedicated consultant who knows your structure. You can reach them at any hour, and every request gets a written answer within 24 hours: the optimised route, what it saves and what we will do next.

Do I have to move country to save tax?

No. Many savings come from how a group is structured and how money moves out of it, with nobody relocating. When a move does make sense, we plan it against each country's actual residency tests.

I already have an accountant. Why would I need you?

Keep them. Most local accountants file very well in one country. We look across the countries and across you and your company, design the structure, and work alongside your existing advisers to carry it out.

How are you different from a Big Four firm?

The Big Four are excellent at corporate tax, and usually handle your personal position through a separate team. We plan both together, under one lead, and we carry out the work (formation, filings, hiring, payouts) rather than handing you a report.

Before you sign: notes from our consultants.

Residency · 7 min read

Choosing a country to move to as an entrepreneur: what actually matters

Headline tax rates are the least useful way to compare countries. How residence is acquired, how foreign income is treated and how long any special regime lasts decide the real outcome.

Selling · 7 min read

Selling your company: why the tax work starts 12 to 24 months before the deal

Most of the tax on a sale is decided long before the heads of terms. Here is what founders can still influence a year or two out, and what becomes fixed once a buyer is at the table.

Registering · 7 min read

Where to register a private aircraft: choosing the registry, the owner and the operator

The registry on the tail decides which aviation authority oversees the aircraft. VAT, customs and income tax follow who owns it, who operates it and where it flies. How to make the decisions together.
