Key Takeaways
- A Spanish resident can incorporate and own an Antigua and Barbuda international business company entirely remotely, with a licensed registered agent handling the filing and identity verified through certified copies prepared in Spain.
- Spanish tax rules can follow the income home regardless of where the company is registered, so owners should check controlled-foreign-company rules, the treaty position, and their reporting obligations in Spain.
- This route fits founders, online businesses, and investors serving clients outside Spain, but is a weaker fit when customers, staff, and operations sit inside Spain.
- Practical setup involves documents from Spain, opening a bank account, economic substance, and planning how profits are brought back to Spain.
Setting up a Antigua and Barbuda company from Spain
Registering a company in Antigua and Barbuda from Spain is a remote process from start to finish. A Spanish resident never needs to travel to the Caribbean: a licensed registered agent handles the filing, and your identity and source-of-funds documents are verified through certified copies prepared in Spain. The vehicle that makes this work is the international business company, an entity built for non-resident ownership and managed entirely from abroad.
This route is most relevant to founders, online businesses, and investors who serve clients outside Spain and want a neutral holding or trading entity. It is a weaker fit for someone whose customers, staff, and operations sit inside Spain, because Spanish tax rules will follow the income home regardless of where the company is registered. Before deciding, confirm your own position under Spain's tax and reporting regime through the Agencia Tributaria.
This guide explains how a Spain resident sets up, owns, and runs such a company, and the home-country rules that decide whether it is worth doing at all.
Why founders in Spain look to Antigua and Barbuda
The appeal is a simple corporate framework with no tax on profits earned outside the jurisdiction, light public disclosure, and full foreign ownership. For a Spanish entrepreneur with international income streams, that combination can simplify how a global business is held.
The pull is rarely a treaty advantage, because none exists between the two countries (more on that below). It is the operational flexibility of a low-friction offshore entity, weighed against the reporting and anti-avoidance rules Spain applies to anything its residents own abroad.

Company types available to non-residents
A non-resident in Spain will almost always use the international business company, the standard offshore vehicle for foreign owners. It allows 100% non-resident ownership, a single shareholder and a single director, and imposes no local tax on income sourced outside the country.
- International business company (IBC): the default choice for trading, holding, and consulting structures owned from abroad.
- Domestic limited company: aimed at businesses operating locally, with local tax exposure, and generally not what a Spain-based remote owner needs.
- Limited liability company / LLC-type entity: available in some forms; useful in narrow cases where flow-through treatment or a partnership-like structure is wanted, but confirm the exact current vehicle and its features with your agent.
For most readers in Spain, the IBC is the entity in question, and the rest of this article assumes it.
Who can incorporate: eligibility for Spain residents
There is no nationality or residence bar. A Spanish citizen or resident can own and direct the company outright, hold all the shares, and act as sole director.
The practical gate is compliance, not eligibility. A licensed registered agent must perform know-your-customer checks on every owner and director, which means certified identity documents, proof of address, and a clear explanation of where the company's funds come from.

How to register a Antigua and Barbuda company from Spain
The sequence is straightforward and runs through your agent:
- Choose and reserve a company name.
- Appoint a licensed registered agent, who is mandatory and also supplies the registered office.
- Complete due-diligence forms and submit certified identity and address documents for each owner and director.
- The agent files the incorporation documents with the registry and pays the government fee.
- You receive the certificate of incorporation, memorandum and articles, and the share register.
No step requires your physical presence. Everything is signed and certified in Spain and couriered or transmitted to the agent.
Documents you need from Spain
Expect to provide, for each shareholder and director:
| Document | Form required |
|---|---|
| Passport | Certified copy |
| Proof of address (utility bill or bank statement) | Certified copy, usually under 3 months old |
| Bank or professional reference | Original or certified, where requested |
| Source-of-funds explanation | Signed declaration, supporting evidence on request |
Certification in Spain is normally done before a notario. Where a document must be recognised abroad, it is legalised with an apostille under the Hague Convention, which Spain administers through the Ministry of Justice and regional bodies; your agent will tell you which documents need the apostille and which a notarial certification alone will satisfy.
Arrange notarisation and any apostille before you submit, since obtaining them after the fact in Spain causes the most common delays for offshore filings.
Antigua and Barbuda Incorporation Pricing
See transparent pricing to incorporate and maintain a company in Antigua and Barbuda.
Costs to set up and maintain
Costs fall into predictable components rather than a single price. Plan for a government incorporation fee, the registered agent's setup fee, and the registered office charge, with optional extras for nominee services, certified document sets, or courier.
Recurring costs are an annual government renewal fee plus the agent and registered-office annual charges. Where the company falls within economic-substance obligations or needs accounting support, budget separately for those. Confirm the current statutory fees with your agent before committing, as government charges are periodically revised.
How long it takes
Incorporation itself is usually quick once documents are complete, often within a few business days to about two weeks. The realistic timeline is driven by your side: gathering certified and apostilled papers in Spain and clearing the agent's due diligence. Banking, addressed next, takes considerably longer than the company formation.
Banking and moving money between Antigua and Barbuda and Spain
Opening a bank account is the hardest part of this exercise, and you should plan for it before you incorporate, not after. An offshore company owned by a Spanish resident with no local operations faces heavy scrutiny, and many banks decline such accounts outright. Realistic options are a local or regional Caribbean bank, an international bank in a third jurisdiction, or a regulated electronic-money or payment institution that accepts offshore entities.
Expect to supply the full corporate pack, proof of the business's activity, and a clear account of where money originates and where it will flow. Account opening commonly takes several weeks to a few months, and remote opening is not guaranteed; some institutions require a director to appear or to pass a video interview.
Moving money back to Spain is where the home-country rules bite hardest. Spain itself does not impose general exchange controls on inbound funds, but transfers are monitored: under EU and Spanish anti-money-laundering rules, banks report and may query large or unusual transfers, and you must be able to evidence the lawful origin of every inflow.
Keep board minutes, dividend resolutions, and invoices for any money you send from the company to yourself in Spain; an unexplained inflow from an offshore company is exactly the pattern Spanish banks and the tax authority flag.
Cross-border declaration thresholds also apply. Carrying cash across the EU external border above the statutory amount must be declared, and Spain requires reporting of certain cross-border movements of funds and means of payment; confirm the current threshold and form before moving large sums.
Tax considerations for a Spain resident owner
Owning an Antigua and Barbuda company does not move your tax residence out of Spain. If you live in Spain, you remain taxable there on your worldwide income, and the company's offshore status does not change that. The points below decide whether the structure helps you or simply adds cost.
Spain's controlled-foreign-company rules
Spain has long-standing CFC rules (transparencia fiscal internacional) designed to stop residents from parking passive income in low-taxed foreign entities. In broad terms, where a Spanish resident controls a foreign company that pays little or no tax and earns mainly passive income (interest, dividends, royalties, certain capital gains, income from related parties), Spain can attribute that income to you and tax it in your hands even if the company never distributes a cent.
A zero-tax Antigua and Barbuda entity owned by a Spanish resident is squarely the kind of structure these rules target. They generally do not bite where the company carries on genuine economic activity with real substance abroad, but a passive holding company will usually fall inside them. This is the single most important point to model with a Spanish tax adviser before you incorporate.
The treaty position
There is no double-tax treaty between Spain and Antigua and Barbuda. That absence matters: there is no reduced withholding, no tie-breaker for residence, and no treaty-based relief if the same income is taxed in both places.
Spain may also treat the destination as a low-tax or non-cooperative jurisdiction for certain purposes, which can trigger stricter reporting, harsher CFC treatment, and limits on deducting payments made to the entity. Verify how Spain classifies the jurisdiction at the time you act, since these lists are updated.
Reporting obligations in Spain
A Spanish resident who owns or directs a foreign company carries real disclosure duties. The well-known one is the Modelo 720 declaration of foreign assets above a threshold, covering foreign accounts, securities, and shareholdings; reporting is informational but the penalties for getting it wrong have historically been severe, so treat it carefully.
Separately, holding shares or a directorship abroad and operating a foreign bank account feed into your annual income tax return and, where relevant, the Bank of Spain's reporting of foreign accounts and transactions. Confirm the current Modelo 720 threshold and which forms apply to your situation, because the obligations stack rather than replace one another.
Bringing profits back to Spain
Money you extract is taxed in Spain on the way in. Dividends from the company are taxable as savings income on your Spanish return; a salary or director's fee is taxed as employment income at your marginal rate.
Because no treaty exists, you cannot rely on treaty relief to soften double taxation, though Spain's domestic rules may give a unilateral credit for foreign tax actually paid, which for a zero-tax entity will often be nil. The practical result is that profits earned offshore are generally taxed in full once they reach you in Spain.
Economic substance
Antigua and Barbuda applies economic-substance requirements that flow from international standards. Entities carrying on certain relevant activities, such as holding, financing, or intellectual-property business, may need to show real local presence: people, premises, and decision-making in the jurisdiction.
For a Spain-based owner this cuts both ways. Meeting substance supports a position that the entity is genuinely active and may temper CFC exposure, but it adds cost; failing to meet it where required risks penalties and tighter scrutiny on both sides. Establish your substance obligations before, not after, you incorporate.
Common mistakes Spain-based owners make
The recurring error is assuming an offshore company makes income invisible to Spain. It does not. CFC attribution, Modelo 720, and worldwide-income taxation mean the structure is fully transparent to the Spanish authorities, and the right question is whether it is compliant and useful, not whether it is hidden.
- Treating zero local tax as zero tax overall, when Spain may tax the same profits through its CFC rules.
- Incorporating before checking how Spain classifies the jurisdiction, which can trigger harsher treatment and disallowed deductions.
- Underestimating banking: forming the company first and discovering no bank will open an account for it.
- Ignoring substance obligations, then facing penalties or a weaker tax position later.
- Missing Spanish reporting deadlines for foreign assets and accounts.
- Sending money to Spain without resolutions or invoices to evidence its source.
Get the Spanish tax and reporting analysis first, then incorporate. Doing it the other way around is how owners end up with an entity that costs more than it saves.
Conclusion
For a Spain-based reader, the realistic verdict is that an Antigua and Barbuda company is a legitimate but tightly constrained tool, useful for genuinely international activity and rarely useful as a way to lower a Spanish tax bill. Because no treaty exists and Spain's CFC rules reach undistributed profits of low-taxed foreign entities, a passive structure often delivers compliance cost without a real saving.
The one thing to confirm before anything else is how your specific income would be treated under Spain's controlled-foreign-company rules and foreign-asset reporting, modelled with a Spanish adviser against your actual facts.

Frequently Asked Questions
Yes. The entire incorporation is done remotely through a licensed registered agent, with your identity and address documents certified before a notario in Spain and apostilled where needed. The only step that may require your presence is opening a bank account, which some institutions handle by video and others do not.
Yes. Full foreign ownership is permitted, and a single person can be the sole shareholder and sole director. The limiting factor is due diligence on the owner, not any ownership restriction.
Almost certainly, yes. As a Spanish resident you are taxed on worldwide income, dividends and salary from the company are taxable when they reach you, and Spain's CFC rules can tax the company's passive profits even before distribution. The offshore status does not remove Spanish tax.
No double-tax treaty exists between the two countries. That means no reduced withholding and no treaty-based relief, so you rely only on Spain's domestic rules, which may give limited unilateral credit for any foreign tax actually paid.
It is the most difficult and slowest part of the process. Many banks decline offshore companies owned by EU residents with no local activity, and those that accept them require detailed proof of business and source of funds, with account opening taking several weeks to a few months.
Incorporation itself is often a matter of days to about two weeks once documents are ready. The realistic end-to-end timeline depends on gathering certified and apostilled papers in Spain and, above all, on banking, which can extend the process by months.
