Dividends from a Luxembourg SARL: 15% withholding, half-dividend and the real cost

Short version. A Luxembourg SARL distributing a dividend must withhold 15% at source on the gross amount, then file the form 900F return and pay that withholding to the Direct Tax Authority collection office within 8 days. For a resident shareholder, those 15% are only an advance: the dividend is then taxed on half of its gross amount, with the balance settled through the annual income tax return.

The question comes up at every year-end among SME owners: how much is actually left when you take €50,000 out of your company? The path runs through three layers of tax, and the 8-day deadline after the funds are made available is the one that catches most people out. Here is the mechanism, with the numbers.

Layer 1: the profit is taxed in the company first

Before any distribution, the company's commercial profit bears corporate income tax (IRC), alongside municipal business tax and net wealth tax. That is the precondition: you only distribute profit that has already been taxed. We work through those three taxes in our article on corporate tax in Luxembourg.

A useful point of vocabulary: only capital companies distribute dividends. In a partnership, the result is taxed directly at partner level whether or not it is paid out, and each partner declares their share of the commercial profit.

Layer 2: the 15% withholding and its 8 days

At the time of distribution, the company must:

• withhold 15% at source on the gross amount allocated;
• file the withholding tax return on income from capital (form 900F) and pay the withholding to the competent collection office of the Direct Tax Authority, in Luxembourg, Ettelbruck or Esch-sur-Alzette;
• do so within 8 days of the income being made available.

Eight days is not eight weeks. In practice this means the distribution decision and the tax step have to be prepared together, not one after the other. It is one reason why a shareholders' meeting that approves a distribution without warning its accountants almost always generates a late filing.

Non-resident shareholders

Where the shareholder is resident outside Luxembourg, the company applies either the standard 15% rate or the reduced rate provided by the applicable double tax treaty between the two countries. If the withholding applied turns out to be higher than the treaty rate, the recipient can claim a refund of the excess from the Direct Tax Authority. This matters for cross-border owners and for structures with foreign shareholders: the treaty rate is checked before the distribution, not after.

Parent companies

Income distributed by a Luxembourg subsidiary to its parent company is exempt from withholding tax where the parent-subsidiary conditions are met at the date the income is made available. Two main routes: a holding of at least 10% of the capital, or an acquisition cost for the participation of at least €1,200,000. Below that, the treaty rate applies again, for instance 15% for an Italian parent holding 7%.

Layer 3: for resident shareholders, the half-dividend system

The resident recipient declares the dividend as investment income. Since the profit was already taxed in the company, the dividend can be 50% exempt where the distributing company is one of the following:

• a fully taxable resident company;
• a capital company resident in a State that has signed a tax treaty with Luxembourg and subject to a tax comparable to IRC, meaning a rate of at least 10.5%;
• a company resident in the European Union covered by the parent-subsidiary directive but not meeting the participation conditions (holding period, 10% threshold, acquisition cost) for the parent-subsidiary regime.

Income tax is therefore calculated on 50% of the gross dividend, before withholding. The taxpayer then pays the difference between the withholding already made and the total tax due. On top of that, an annual allowance of €1,500 applies to total investment income, raised to €3,000 for jointly taxed spouses or partners.

The calculation, in numbers

Here is the authority's reference example, for a taxpayer with a 39% marginal rate and a gross dividend of €100.

At that marginal rate, the personal tax charge comes to 19.5% of the gross. The point to remember is not the percentage, which depends on your marginal rate, but the timing gap: you receive 85 and still owe 4.50. An owner who distributes €60,000 and treats the €51,000 received as definitively theirs is setting up a several-thousand-euro adjustment at the next filing. That is precisely the kind of gap that real-time bookkeeping lets you anticipate, rather than discover eighteen months later.

The real trap: hidden profit distributions

All income distributed to shareholders in the broad sense counts as a dividend, including income that does not go by that name. Where a shareholder receives an advantage they would not have obtained had they not been a shareholder, the authority reclassifies that advantage as a hidden profit distribution. The classic cases: an interest-free loan or one below market rate, a property made available rent-free, a sale at below the asset's value.

The authority's own example makes the point. A company sells its shareholder a property worth 1,000 for 800, having acquired it for 400. The sale is deemed made at 1,000: the taxable profit rises from 400 to 600, and the advantage reclassified as a hidden distribution comes to 200. That amount is included both in the company's taxable income and in the recipient's. Taxed twice.

In practice, two accounts warrant particular attention in an SME: the shareholder current account and benefits in kind. We cover the first in our article on shareholder current accounts in Luxembourg, and the second on the most common case, the company car.

Who dividends do not suit

Let us be plain: a dividend is not always the right tool. It requires available, already taxed profit, it can only be decided in a shareholders' meeting, and it carries no social security entitlement. An owner who needs regular income, pension rights and health cover cannot rely on this channel alone. Conversely, a company financing its growth is often better off keeping its reserves than taking them out only to put them back in. The trade-off is made case by case, with a figure in front of you, not with a general rule.

Frequently asked questions

What is the withholding tax on dividends in Luxembourg?

15% of the gross amount allocated. The company must file form 900F and pay that withholding to the Direct Tax Authority collection office within 8 days of the income being made available.

How are dividends taxed for a resident shareholder?

They are declared as investment income and can be 50% exempt, subject to conditions relating to the distributing company. Tax is calculated on half the gross dividend, with the 15% withholding credited against the final tax. An annual allowance of €1,500 applies, raised to €3,000 for jointly taxed couples.

Does a non-resident shareholder pay the same withholding?

The standard rate is 15%, unless a lower rate is set by the tax treaty between Luxembourg and their country of residence. Where the withholding applied exceeds the treaty rate, they can claim a refund of the excess from the Direct Tax Authority.

What is a hidden profit distribution?

An advantage granted to a shareholder that they would not have obtained had they not been a shareholder: an interest-free loan, a property made available rent-free, an undervalued sale. The authority reclassifies it as a dividend and includes it in both the company's and the recipient's taxable income.

Can a SARL distribute a dividend without a shareholders' meeting?

No. Regular dividends are those formally approved by the shareholders' meeting and recorded as such in the accounts. Any transfer of value that is not approved risks reclassification as a hidden profit distribution.
