How much does Andorra tax trading and investing in shares? This guide goes beyond the 0% headline

Every few months, we see the same piece of information doing the rounds: “Trading is tax-free in Andorra”. This is only half the story, and it could cost you dearly in two ways: you may end up paying more than you should if you assume that everything is taxed at the same rate, or you could be in for an unpleasant surprise when the tax authorities in your country of origin present you with an exit tax bill.
Rather than just repeating the headlines, this guide delves into the nuances that determine exactly how much you’ll pay depending on how you trade, where you were tax resident before moving, and which financial instruments you use.

1. Why “How much tax do you pay in Andorra?” is the wrong question

The important question is not how much tax you pay in Andorra, but what is taxed and how. The Principality doesn’t have a single tax rate for trading. Instead, there’s a total exemption for certain assets, a savings income regime with tax brackets of 0% and 10%, and a 10% corporation tax for those operating through a corporate structure.
The end result – what you will ultimately have left in your pocket – depends on these three variables, which almost no guide clearly distinguishes:

• What you buy and sell: shares and fund units are taxed differently from CFDs, futures or forex.
• How you trade: factors like the frequency and volume of your trades can also affect the tax classification of your activity.
• Where you’re from: the tax savings differ when compared to Spain, France or Germany, and your country of origin may charge you an exit tax before you leave.

2. The “famous” Article 5k, and the small print that nobody explains

The centrepiece of the system is Article 5k of the Personal Income Tax Act. It exempts capital gains from the sale of shares, company shares, and units in collective investment schemes (such as funds and ETFs), provided that the taxpayer did not hold more than 25% of the entity’s capital at any time during the previous twelve months.
For a retail investor with a portfolio of shares or ETFs, this effectively means zero tax on capital gains. However, there are limitations to the exemption that are often overlooked:

• It does not cover pure derivatives. CFDs, futures, options and leveraged products are not “securities” as defined in Article 5k. They are taxed as investment income: the first €3,000 per year is exempt and a tax rate of 10% is applied to amounts above this figure.
• Speculative forex trading is not covered, unless it is conducted through regulated funds.
• The distinction regarding cryptocurrencies is narrower than is often claimed. Since 2023, they have been treated as capital gains and will be subject to personal income tax, with the same brackets as non-exempt assets (0% up to €3,000, then 10%). Cryptocurrencies will not be treated as “shares” unless they are held through a qualifying exempt vehicle.

This means that if your portfolio includes shares, ETFs and CFDs, you will be subject to two parallel tax regimes within the same brokerage account and will need to separate them on your tax return.

3. Trader or investor? The distinction Andorra does not currently make (and why it works in your favour)

This is one of the most confusing points, and something that generic guides rarely address. Unlike Spain, Andorra does not have an established legal doctrine that reclassifies the buying and selling of securities as an “economic activity” when done on a regular basis.
In Spain, the Tax Agency may determine that a high and systematic volume of transactions constitutes a professional activity, which has implications for tax classification and the applicable tax base.
Since Andorran legislation does not distinguish between passive portfolio management and active trading when it comes to private individuals, someone who trades once a year is treated in the same way as someone who trades a hundred times a month, provided the transactions remain within the scope of shares, equity interests and funds covered by Article 5k.
While this is not a permanent loophole, it is currently one of the real – and rarely mentioned – reasons why high-frequency equity traders are considering relocating.

4. Dividends: the crack in Andorra’s tax façade

If capital gains are the system’s strong point, then the weak point is dividends. It is important to be precise, because this is where expectations are most often inflated:

• Dividends from Andorran companies are exempt for tax residents.
• Dividends from companies based in countries with which Andorra has a double-taxation agreement (Spain, France, Portugal, Luxembourg and the United Kingdom are just a few of the more than twenty agreements in force in 2026) are taxed in Andorra at the residual rate after the application of international double-taxation relief. The effective maximum is around 10% when combining withholding tax and Andorran personal income tax.
• Dividends from US companies are where most traders get caught out. Andorra does not have a double-taxation agreement with the United States. A dividend from a US-listed share may be subject to a withholding tax of between 15% and 35%, and there is no equivalent credit mechanism to the one that exists for investors from countries with a treaty. This withholding tax cannot be offset by Andorra.

For a portfolio with a significant weighting in US technology companies that pay dividends, the actual tax savings are significantly lower than the “0% tax” headline suggests.
Therefore, if your investment strategy relies more on dividends than capital gains, the actual tax savings from moving to Andorra may be much lower than the share exemption suggests.

5. Individual or company: the real break-even point

Most guides propose operating through an Andorran company as a general recommendation for “high-net-worth individuals”, without providing any specific figures. In reality, it’s worth doing the maths.
Operating as an individual gives you full access to the 0% capital gains tax exemption under Article 5k.
Operating through a company removes this exemption – the company’s profits are taxed at a flat rate of 10% regardless of the source of the gain – but it opens up other possibilities, such as the deduction of operating expenses (e.g. market data, commissions, software, and even part of the office rent), depreciation and the ability to keep profits within the company without incurring additional personal tax liability until they are distributed as dividends.
When is it worth setting up a company? Generally speaking, it starts to make sense when:

• Your actual deductible expenses, such as tools, data, office costs and staff, account for a significant portion of your profits, which is rare in pure stock trading.
• You also trade intensively in derivatives or foreign exchange (forex), where the personal tax-free allowance under Article 5k does not apply anyway, thereby equalising the effective tax rate between the two approaches.
• You aim to reinvest profits on an ongoing basis, so you don’t need to have the liquidity available personally, thus deferring the second layer of taxation.
• For an investor focused on shares and ETFs who already benefits from a 0% tax rate as a private individual, setting up a company does not reduce taxes; it introduces them where none previously existed. This is a common mistake.

6. The entry price: the cost of becoming a resident in 2026

This is where the analysis often ends prematurely, even though it’s the most important factor when determining whether relocation is worthwhile. Trading is not tax-free: you have to obtain tax residency, and from 2026 this has become substantially more expensive.

If you choose active residency, either by working or setting up or managing a business in Andorra, you will need to make monthly contributions to the CASS (the Andorran social security scheme). These monthly contributions amount to around €450–€500 for self-employed individuals, and you will also need to fulfil the requirement of spending at least 183 days in Andorra each year.
If you choose passive residency (i.e. living off investment income without working in the Principality), the regulations, which are tightening in 2026, generally require the following:

• A minimum investment of €1,000,000 in Andorran assets (securities, shares, deposits, funds) or €800,000 in a residential property in the Principality, which must be maintained for the entire duration of the permit.
• A non-refundable initial contribution of €50,000 per main applicant, plus €12,000 for each dependant.
• Private health insurance at approximately €100–€150 per month (there is no access to social security without employment).
• A minimum stay of 90 days per year is required to retain the permit, or 183 days if you are also seeking tax residency in Andorra.

7. Three mistakes that can turn tax savings into a problem

While it is true that tax savings exist, you need to ensure that you do things properly to avoid any unpleasant surprises. Poor management or a lack of foresight when transferring your residence can have negative consequences, particularly in the following cases:

• Ignoring the Spanish exit tax. If you’re a Spanish tax resident and you hold a stake of more than 25% in a company, or if your assets in securities exceed certain thresholds, then transferring your residence may trigger an exit tax on unrealised capital gains. This tax is calculated as if you had sold your shares before leaving Spain. This does not apply to most retail investment portfolios, but it does apply to individuals who hold significant shares in their own company or have a high net worth concentrated in a small number of securities. In this article, we summarise the key points to bear in mind regarding the exit tax.
• Assuming that Andorra does not require the disclosure of information. Although Andorra does not have an exact equivalent to the Spanish Form 720, it is recommended – and in practice expected – that you inform the Andorran tax authorities of any relevant assets held abroad, particularly if you plan to repatriate profits at a later date.
• Confusing “not paying tax in Andorra” with “not paying tax anywhere”. If you hold accounts or have brokerage accounts that are subject to withholding tax (with the United States being the clearest example), that withholding tax applies regardless of where you live. Moving does not eliminate the withholding tax; it merely removes – or reduces – the additional layer of personal taxation.
