Key Takeaways
- A Spanish resident can incorporate and own a Nauru company entirely from Spain, since a licensed local registered agent handles formation from documents you send.
- Owners must check how Spain's anti-deferral and CFC rules, the treaty position, and home reporting obligations apply to a Nauru company before committing.
- Banking is a central practical hurdle, as Nauru has a limited international banking sector and a history of anti-money-laundering concerns that affect opening a usable account.
- Because Nauru sits at the cautious end of offshore options, the realistic test is whether the structure withstands Spanish tax scrutiny rather than whether it can be set up.
Setting up a Nauru company from Spain
Registering a company in Nauru from Spain is technically possible, but it sits at the cautious end of offshore options for a Spanish resident. Nauru is one of the smallest jurisdictions in the world, with a limited international banking sector and a history of past anti-money-laundering concerns, so the practical question for someone in Madrid or Barcelona is rarely "can it be done" but "will it withstand Spanish tax scrutiny and let me open a usable bank account." Both points deserve honest weighing before you commit.
The factor that makes incorporation workable from a distance is that the entire formation is handled through a licensed local registered agent acting on instructions and documents you send from Spain. You never need to travel.
This guide is for Spanish-resident founders, investors, and their advisers who want to understand how a Nauru entity is owned and run remotely, and how Spain's own rules on foreign companies bear on the decision. Before you act, treat your personal Spanish tax position as the deciding factor, and read the Agencia Tributaria guidance on declaring foreign assets alongside this article.
Why founders in Spain look to Nauru
The draw is the classic offshore profile: no corporate income tax on the foreign-source profits of a non-resident-owned entity, confidentiality, and a light local filing burden. For a holding structure or a passive vehicle, that simplicity can appeal.
Set against this is a hard reality. Nauru's financial infrastructure is thin, international banks are wary of accounts linked to the jurisdiction, and Spanish anti-deferral and reporting rules treat low-tax jurisdictions firmly. For most Spanish residents, the tax advantage is neutralised at home before it is ever enjoyed, which is the central tension this article returns to.
Company Incorporation in Nauru
Set up your company in Nauru with Expanship handling registration end to end.
Company types available to non-residents
The vehicle most relevant to a foreign owner is a corporation limited by shares formed under Nauru's companies legislation. It gives limited liability, allows full foreign ownership, and is the standard form for holding or international trading activity.
Nauru has historically also been associated with trust and special-purpose structures used in international planning. Availability and licensing of these change over time, so confirm what a current registered agent can lawfully form before assuming a particular vehicle exists. For most Spanish founders, the limited company is the only structure worth examining.
Who can incorporate: eligibility for Spain residents
There is no Nauru nationality or residence requirement for shareholders or directors, so a Spanish resident can own one hundred percent of the shares and act as sole director. A local registered agent is mandatory, and the company must maintain a registered office in the jurisdiction.
What constrains you is not Nauru's law but Spain's. As a Spanish tax resident, owning and controlling a foreign company triggers reporting and potential anti-deferral consequences at home regardless of how permissive the destination is.
Ongoing Compliance in Nauru
Keep your Nauru entity compliant with filings, returns, and statutory obligations.
How to register a Nauru company from Spain
The sequence is straightforward and runs entirely through your agent:
- Engage a licensed registered agent and complete their due-diligence checks.
- Reserve a company name and confirm it is available.
- Provide certified identity and address documents for every shareholder, director, and beneficial owner.
- Approve the constitutional documents and share structure prepared by the agent.
- The agent files for incorporation and the company is entered on the register.
- Receive your incorporation certificate and corporate documents, then begin the bank-account process separately.
Expect the due-diligence stage to take longer than the filing itself, particularly given heightened scrutiny of small offshore centres.
Documents you need from Spain
Because you are sending documents abroad, certification matters. Spain is party to the Hague Apostille Convention, so a Spanish notary public can certify copies and signatures, and the apostille is then issued through the relevant authority. The Spanish notaries' portal explains where apostilles are obtained.
| Document | Form required |
|---|---|
| Passport or national identity document | Notarised copy, apostilled |
| Proof of Spanish address (utility bill or bank statement) | Recent, certified |
| Bank or professional reference | Original, sometimes apostilled |
| Source-of-funds evidence | As requested by agent or bank |
| Company name and activity description | Provided to agent |
A non-Spanish document may need a sworn translation; confirm the language your agent and bank accept.
Nauru Incorporation Pricing

Costs to set up and maintain
Costs fall into predictable components rather than a single figure. Plan for a government incorporation and annual licence fee, the registered agent's formation charge, and a recurring registered-office and agent retainer.
- Government incorporation and annual fees, payable to the registry
- Registered agent and registered office (annual)
- Apostille and sworn-translation costs incurred in Spain
- Optional: nominee services, accounting, and economic-substance support
Confirm the current official registry fee with your agent before committing, as small jurisdictions adjust these periodically. The Spain-side certification costs are modest and one-off.
How long it takes
Formation filing itself is usually quick once papers are in order. Realistically, allow two to four weeks from engaging an agent to holding incorporation documents, with most of that time spent on due diligence and apostille handling in Spain.
Banking is the slow and uncertain stage and should be planned as a separate timeline that can run several weeks or longer, with no guarantee of approval.
Banking and moving money between Nauru and Spain
This is where many Spanish-resident plans stall. Few international banks readily open accounts for companies registered in very small offshore centres, and a Nauru-incorporated entity will face enhanced scrutiny almost everywhere it applies. Many owners end up banking the company in a third jurisdiction or through a regulated payment institution rather than in Nauru itself.
Expect to provide the full corporate chain, apostilled personal documents, a clear business rationale, and detailed source-of-funds evidence. The bank will want to understand why a Spanish resident is using this structure, and a weak answer is a common reason for rejection.
On the Spain side, moving money is not blocked but it is watched. Spain operates within the EU framework on capital movement, so transfers in and out are generally free, but Spanish banks and the authorities apply anti-money-laundering checks, and significant cross-border payments are reported.
Any Spanish-resident-held foreign bank account above the relevant reporting threshold must be declared to the Spanish tax authority on the annual foreign-asset return. Treat this as mandatory and confirm the current threshold with a tax adviser, because the penalties for omission have historically been severe.
Plan the banking route before you incorporate, not after. A company with no usable account is a liability, not an asset.
Tax considerations for a Spain resident owner
Spain's anti-deferral and CFC rules
Spain applies controlled-foreign-company rules that are designed precisely to catch structures like this. Broadly, where a Spanish resident controls a foreign entity that pays little or no tax and earns mostly passive income (dividends, interest, royalties, capital gains, certain service income), Spain can attribute that income to you and tax it in Spain even if the company distributes nothing.
A further trigger applies when the foreign tax paid is below a set proportion of what Spanish corporate tax would have been. Because Nauru imposes no corporate tax on such profits, a Nauru company owned and controlled from Spain is a strong candidate for this attribution. The practical effect is that the offshore "saving" can disappear at the Spanish level. Confirm how the rules apply to your specific income mix with a Spanish adviser, since the relief for genuine business activity is narrow.
The treaty position
There is no double-taxation treaty between Spain and Nauru. That absence matters: you cannot rely on a treaty to reduce Spanish taxation, to allocate taxing rights, or to access reduced withholding, and there is no treaty-based exchange-of-information or relief mechanism to lean on.
It also means Spain treats the structure under its domestic anti-avoidance rules with no treaty protection, which generally works against the taxpayer rather than for them.
Reporting obligations in Spain
A Spanish resident who owns shares in, directs, or benefits from a foreign company faces several disclosure duties. Foreign assets and accounts above the relevant thresholds must be reported annually on the foreign-asset declaration, and foreign company participations and accounts can fall within this regime.
Separately, Spain's central bank and statistical reporting can require disclosure of foreign investments and balances. Acting as a director of a foreign company and holding a foreign account are both visible to the authorities through these channels, so non-disclosure is a meaningful risk, not a theoretical one.
Bringing profits back to Spain
Money you extract is taxed in your hands as a Spanish resident. Dividends from the company are taxable as savings income on your Spanish return, salary is taxed as employment income, and gains on selling the shares are taxable in Spain.
Because no treaty exists, there is no reduced cross-border withholding to coordinate, but equally no foreign tax credit to offset, since Nauru levies nothing. In effect, profits that were untaxed offshore are taxed on the way home, on top of any CFC attribution that may already have applied.
Economic substance
Like other low-tax centres responding to international standards, Nauru has moved toward substance expectations for entities carrying on certain activities. A company that exists only on paper, controlled entirely from Spain, may struggle to demonstrate genuine local substance, which weakens its standing both locally and under Spanish anti-avoidance review. Confirm the current substance requirements for your intended activity before relying on the structure.
Common mistakes Spain-based owners make
The recurring error is treating Nauru's zero tax as the end of the analysis. For a Spanish resident, the home-country position usually determines the outcome, and assuming otherwise leads to attributed income, back taxes, and penalties.
- Incorporating before securing banking, then finding no institution will open an account
- Failing to file Spain's foreign-asset declaration, where penalties have historically been heavy
- Assuming undistributed offshore profit escapes Spanish tax, ignoring CFC attribution
- Running the company entirely from Spain while claiming it is foreign-managed, exposing it to Spanish residence and substance challenges
- Overlooking that the reputational profile of the jurisdiction complicates dealings with EU banks and counterparties
The owners who avoid trouble are those who model the Spanish tax result first and decide whether the structure still makes sense.
Conclusion
For most people taxed in Spain, a Nauru company delivers far less than it appears to. The combination of Spanish CFC attribution, full reporting duties, no treaty, and a banking sector that resists this kind of structure means the offshore tax benefit is usually neutralised at home while the friction remains.
If you still see a genuine, non-tax reason to proceed, the one thing to settle first is how Spain's anti-deferral rules and foreign-asset reporting apply to your exact income and ownership, confirmed in writing by a Spanish tax adviser before any document is signed.

Frequently Asked Questions
Yes. A licensed registered agent handles the entire formation on your instructions, using identity documents you certify with a Spanish notary and apostille, so no travel is required.
Yes. Nauru imposes no nationality or residence restriction on shareholders or directors, so you may own all the shares and act as sole director, subject to your Spanish reporting and tax duties as the owner.
This is the hardest part. International banks scrutinise companies from small offshore centres heavily, so many owners bank in a third jurisdiction or through a regulated payment institution, and approval is never guaranteed. Arrange banking before you incorporate.
Very likely. Spain's controlled-foreign-company rules can attribute the entity's low-taxed passive income to you and tax it in Spain even if nothing is distributed, and money you later draw out is taxed again in your hands.
No. With no double-taxation treaty in place, you cannot rely on treaty relief or reduced withholding, and Spain applies its domestic anti-avoidance rules without any treaty protection for you.
Formation typically takes two to four weeks once due diligence and apostilled documents are complete. Banking runs on a separate, longer, and less certain timeline that you should plan independently.
