Selling an LLC as a Spanish resident requires reviewing the transaction before signing the sale and purchase agreement. The tax treatment depends on how the LLC is classified in Spain, its tax treatment in the United States, whether the entity interests or its assets are being sold, whether it has business activity or real estate in the US, and who holds the interest.
At Barcelona Tributario, we specialise in international tax and tax planning for business owners, investors and wealth holders with interests in different countries. We analyse these transactions from a Spanish perspective and coordinate with the US adviser to prevent a commercial decision from resulting in unexpected taxation.
Quick answer: a Spanish tax resident is taxed on worldwide income, but not all LLCs receive the same tax treatment. Before calculating the gain, it is necessary to determine whether the entity is regarded as tax-transparent in Spain. If the disposal is classified as a capital gain included in the savings income tax base, the current scale reaches 30% on the portion exceeding €300,000. Additional taxes or withholding may apply in the United States depending on the LLC's classification, activity and assets.
Spanish tax residence determines the starting point
More than 183 days is not the only criterion
An individual may be a Spanish tax resident if they spend more than 183 days in Spain during the calendar year, but also where the main centre or base of their activities or economic interests is located in Spain. There is also a presumption linked to the habitual residence of a spouse who is not legally separated and dependent minor children.
Selling your business through an LLC as a Spanish resident can have highly significant tax consequences if it is not planned in advance. Speak to our specialists before taking any steps and make sure the transaction is optimised from the outset.
If there is a possibility of dual residence between Spain and the United States, the Double Tax Treaty should also be reviewed before assuming which state is considered the country of residence for treaty purposes.
Spanish residents are taxed on worldwide income
If you are subject to Spanish personal income tax (IRPF), a gain arising from an international transaction does not fall outside the scope of tax merely because the agreement is signed in Delaware, Florida, Texas or any other state. Therefore, when selling an LLC as a Spanish resident, Spanish tax planning should be carried out before finalising the price and transaction structure.
The first question is not how much you will pay: it is how the LLC is classified
Not all LLCs are treated the same for tax purposes in Spain
The legal form “LLC” does not, by itself, determine its Spanish tax treatment. In its Resolution of 6 February 2020, the Directorate-General for Taxation (DGT) established three basic characteristics for an overseas entity to be regarded as operating under an income attribution regime: it must not itself be subject to a personal income tax in its country; income must be attributed for tax purposes to members merely as a result of being earned; and the income must retain for them the nature of the source from which it arises.
It is therefore necessary to review the LLC's documentation and its US federal tax treatment. The tax election made in the United States is essential information, but we do not recommend automatically transferring US classifications to the Spanish system without carrying out a full analysis.
A transparent LLC should not automatically be treated as an opaque company
If the LLC meets the requirements to be considered an income attribution entity in Spain, income generated during its lifetime may have had to be attributed to the Spanish member under the relevant rules.
This affects the analysis of a future disposal. It is not prudent to calculate the transaction as though simple shares in a Spanish company were being sold without first examining the LLC's tax history, income already declared, and the legal and tax nature of what is actually being transferred.
Tax classification and Form 720 are separate matters
Recent DGT guidance has noted that an interest in a US LLC with its own legal personality may fall within the Form 720 reporting obligation as an interest in a foreign entity, even where the LLC is a disregarded entity in the United States.
Therefore, tax transparency does not necessarily mean that the interest ceases to exist for all Spanish reporting purposes.
How the sale may be taxed under IRPF in 2026
Where an interest in a tax-opaque entity is transferred
Where the transaction is classified as the transfer of an interest in a non-transparent entity, the difference between the tax disposal value and the tax acquisition value may give rise to a capital gain or loss which is generally included in the savings income tax base for IRPF purposes.
In 2026, the generally applicable combined savings income tax scale is as follows:
| Savings taxable income band | Combined rate |
|---|---|
| Up to €6,000 | 19% |
| From €6,000 to €50,000 | 21% |
| From €50,000 to €200,000 | 23% |
| From €200,000 to €300,000 | 27% |
| Over €300,000 | 30% |
The top rate increased to 30% with effect from 2025. A separate additional Catalan scale should not then be added to the same gain: the savings income scale already combines the state and regional components provided for under the IRPF Act.
Where the LLC is under an income attribution regime, the calculation requires more work
For a transparent entity, we do not recommend automatically applying the formula of “sale price less initial contribution” without reconstructing its history. It may be necessary to analyse income already attributed, contributions, distributions, tax bases and the nature of the transfer.
This is particularly important where the LLC has operated for years, retained profits, made distributions or held assets with unrealised capital gains.
Capital losses may be relevant
Where the gain ultimately forms part of the savings income tax base, the offsetting rules for losses and negative balances from previous tax years should also be reviewed. The tax outcome does not depend solely on the LLC's sale price, but on all income included in the taxpayer's savings income tax base.
The United States may also have taxing or withholding rights
The Treaty does not mean the US will never tax the gain
Article 13 of the treaty between Spain and the United States provides that gains not covered by its specific paragraphs may only be taxed in the transferor's country of residence. However, before applying that residual rule, it is necessary to determine what is being transferred and whether the income falls under other treaty paragraphs or rules.
Therefore, when selling an LLC as a Spanish resident, we do not recommend assuming in advance that the entire gain is taxable exclusively in Spain.
An LLC treated as a partnership may trigger 10% US withholding
US legislation contains a specific rule for transfers of certain interests in partnerships. IRC 1446(f) may require the buyer to withhold 10% of the amount realised where part of the gain is treated as effectively connected with a US trade or business, unless an exemption or certification applies.
This withholding should not be confused with the final tax. It must also be distinguished from FIRPTA, which contains specific rules for US real property interests.
Double taxation can be relieved, but not always euro for euro
Where the United States may tax income under the Treaty, Spain provides mechanisms to eliminate double taxation. Article 24 of the Treaty and domestic rules allow, within their limits, a deduction for tax actually paid in the United States.
The Spanish tax credit is limited. It is therefore essential to know which US tax is final, which amount is merely withholding on account, and which documents properly evidence payment.
Form 720, FATCA and reporting obligations
The LLC interest may need to be reported on Form 720
Form 720 includes securities or rights representing interests in legal entities located abroad. The DGT has confirmed in recent consultations that interests in certain US LLCs may fall within this category.
Every LLC sale has its own tax considerations based on your circumstances as a Spanish resident. Tell us the details of your transaction and we will explain exactly what prior analysis you need to avoid surprises from the Spanish tax authorities.
The €50,000 threshold must be analysed in accordance with the rules for the relevant category. It is not correct simply to state that there is an obligation because “the LLC has assets worth more than €50,000”. What must be assessed is the right or interest that must be reported and the applicable valuation rules.
If there was already a reporting obligation and the interest is subsequently sold, it must also be checked whether the loss of ownership must be reported.
FATCA and CRS are not the same
Spain and the United States have a bilateral FATCA agreement providing for the reciprocal automatic exchange of certain financial account information. This system should not be confused with the OECD's CRS.
The existence of information exchange makes it especially important for ownership, accounts linked to the transaction and the declared gain to be consistent with one another. However, it is also incorrect to state that the Spanish Tax Agency (AEAT) automatically receives every LLC sale price merely because FATCA exists.
Sale of the interest, sale of assets and ownership through a Spanish company
A share deal and an asset deal can produce very different outcomes
It is one thing for the member to sell their interest or membership interest, and another for the LLC itself to sell its assets and then distribute the cash. The latter structure can result in taxation at different levels and times.
When considering selling an LLC as a Spanish resident, we model both alternatives before finalising the agreement, as a structure that is attractive to the buyer may be much less efficient for the seller.
Where the owner is a Spanish company, corporate tax rates have changed
In 2026, the general Corporate Income Tax rate remains 25%, but different rates apply to certain entities. Small and medium-sized enterprises meeting the requirements of Article 101 of the Corporate Income Tax Act (LIS) are temporarily taxed at 23%, while entities with turnover below one million euros generally apply 19% to the first €50,000 of taxable income and 21% to the remainder, subject to exclusions.
If the LLC is a tax-opaque entity and the requirements of Article 21 LIS are met, positive income from the transfer of the interest may benefit from the participation exemption, which generally exempts 95% of the income. Among other matters, the percentage interest, holding period and tax treatment of the foreign entity must be reviewed.
A transparent LLC is not automatically equivalent to controlled foreign company taxation
The income attribution regime and the controlled foreign company regime under Article 100 LIS are different concepts. It is not correct to state that an LLC considered transparent in Spain is automatically taxed under the CFC regime in Article 100.
The correct classification must be established before applying an exemption, adjusting a tax value or deciding which taxpayer reports the income.
How we plan an LLC sale at Barcelona Tributario
We first reconstruct the LLC's tax history
Before selling an LLC as a Spanish resident, we review the incorporation and Operating Agreement, US tax elections, federal and state tax returns, contributions and distributions, Spanish tax returns, Form 720 where applicable, bank accounts and documentation supporting the acquisition value.
We then compare the sale of the interest with an asset sale, calculate the Spanish impact and coordinate US withholding or taxes with the local adviser.
A change of residence before selling must also be analysed
Moving outside Spain shortly before a transfer does not automatically mean that the capital gain falls outside the Spanish tax system. Article 95 bis of the IRPF Act regulates the so-called exit tax where certain residence and value requirements are met.
The objective thresholds include an aggregate value of interests exceeding €4,000,000 or, in certain cases, an interest exceeding 25% with a value above €1,000,000. Any change of residence before a significant sale should therefore be planned with particular care.
Frequently asked questions about selling an LLC as a Spanish resident
Do I have to declare the sale of my US LLC in Spain?
If you are a Spanish tax resident, you must analyse the income arising from the transaction under IRPF or, where the owner is a Spanish company, under Corporate Income Tax. The precise taxation depends on the LLC's tax classification and the sale structure.
Do not let poor tax planning reduce the value of years of work. At Barcelona Tributario, we help you structure the sale of your business through an LLC in the most efficient and secure way for your wealth.
Are all LLCs considered transparent in Spain?
No. The DGT requires an analysis of whether the foreign entity meets the characteristics of the income attribution regime. The US classification is essential, but the label “LLC” alone does not determine the Spanish treatment.
What is the maximum IRPF rate on a savings capital gain in 2026?
The combined scale reaches 30% on the portion of savings taxable income exceeding €300,000, provided that the income from the transaction is indeed included in that tax base.
Can the United States withhold tax even if I am a Spanish tax resident?
It can. For example, the transfer of certain partnership interests may be subject to withholding under IRC 1446(f), and specific rules apply to real estate assets. US rules must be coordinated with the Treaty.
Do I have to file Form 720 for an LLC?
There may be an obligation. The DGT has confirmed that interests in certain LLCs with legal personality may form part of the securities and interests category on Form 720. The value, thresholds and possible exemptions must be reviewed.
Is it better to sell the LLC or for the LLC to sell the assets?
There is no universal answer. US and Spanish taxation may differ significantly between an interest sale and an asset sale followed by a distribution. Both alternatives should be modelled before the price is finally negotiated.
Can I move outside Spain before selling to avoid being taxed there?
A genuine change of residence may alter future taxation, but the Treaty, effective residence and the possible exit tax under Article 95 bis must be reviewed. In high-value transactions, this decision should not be taken without prior analysis.
