How to set up an offshore company or account, step by step, and stay legal

The real steps, the real costs, and the reporting forms that decide whether this is smart planning or a crime. Read the last section twice.

Offshore8 min readBusiness owners with international income, people relocating, and anyone being sold an offshore package.

The short answer

Setting one up is easy and legal: register a company abroad, open its bank account, run it properly.
Staying legal is the hard part: your home country taxes you on what you control and what you earn, wherever the company sits.
An offshore company only saves tax when there is real substance abroad: real office, real decisions, real business. A mailbox saves nothing.

Setup cost

$1,500 to $5,000

Agent, registered office, filing

Yearly running

$2,000 to $10,000+

Agent fees, accounts, filings

The part nobody sells

Reporting at home

UK, US and AU all require disclosure

Do it in this order

1Be honest about the reason. Trading internationally, asset protection, or holding foreign investments are real reasons. Hiding income from your own tax office is a crime, not a structure.
2Pick the jurisdiction for business reasons first: legal system, banking access, treaties with your country, reputation. The zero tax sticker comes last.
3Incorporate through a licensed registered agent in that jurisdiction. You will need certified ID, proof of address, and a written description of what the company actually does.
4Pass the bank's due diligence and open the business account. Expect weeks of questions about where the money comes from. Banks now share account data with your home tax office automatically.
5Create real substance if you want the tax treatment: local director or office, board meetings held there, decisions made there. Paper companies are ignored by tax authorities.
6Register the company with your home tax office where required. UK: controlled foreign company rules. US: Form 5471 for foreign corporations and FBAR for foreign accounts. Australia: controlled foreign company and transferor trust rules.
7File in both countries every year: the offshore filings and your home country return declaring your interest and the income.
8Keep money trails clean. Moving your own money in and out is legal; disguising whose money it is, is money laundering.

Only if you want the detail

Why people genuinely do it

These are the legitimate uses, and they are common.

Why it usually does not save you tax

If you live in the UK, US or Australia and control a foreign company, your home rules generally tax its profits as if they were yours, every year, whether or not you take the money out.

What it costs when done properly

Budget for the full picture, not the agent's headline price.

The honest verdict for most readers

If your business and your life are in one country, a domestic company plus the ordinary reliefs in this app will beat an offshore scheme on cost, risk and sleep.

What people get told, and what is true

An offshore company means zero tax.

The company may pay zero where it sits. You, where you live, usually still owe tax on it. Both things are true, and salesmen mention only the first.

They will never find out.

Over 100 countries automatically swap bank account data with each other every year. Your home tax office probably already knows about the account.

Apple does it, so I can too.

Apple has real operations, thousands of staff and real costs abroad. The laws that work for substance punish paper shells. And even Apple's arrangements have been dragged through courts and repaid.

Now do it on your numbers

Reading is the easy half. The saving comes from applying this to your income, your country and this tax year, with the deadline written down.

Where this comes from

General guidance, not personal advice. Anything involving a company, a trust or another country should be checked by a qualified accountant or tax adviser before you act.
