Shareholder current account in Luxembourg: the rules

What is a shareholder current account in Luxembourg?

A shareholder current account in Luxembourg is a debt or a receivable between a company and its shareholder: neither a capital contribution nor a dividend, but repayable funding, posted among the third-party accounts of the standard chart of accounts, which must carry arm's length interest and be split on the balance sheet by residual maturity.

The distinction from a contribution is not a formality; it drives everything else. A contribution increases equity, goes through a shareholders' decision and, for a public limited company, through a notarial deed; it cannot be repaid without reducing capital. A current account, by contrast, is created by a single transfer and extinguished by another. That very ease is what draws the attention of the Luxembourg Inland Revenue: the flexibility of an undocumented flow turns into recharacterisation risk.

Two positions exist, and they do not call for the same review. The credit current account is the one everyone has in mind: the shareholder has advanced funds and the company owes them. The questions are then the rate paid and the level of debt reached. The debit current account is the reverse: the company has advanced funds to its shareholder, and the control point becomes the absence of any interest charged.

Between the two, practice produces a third situation, the most frequent in the files we take over: an account whose balance flips several times during the period, with no written agreement, no maturity and no interest. That position is not neutral in accounting terms, because it makes the maturity split required on the balance sheet indefensible, nor in tax terms, because it leaves the authorities free to set the missing market rate themselves.

Where does a shareholder current account sit in the annual accounts?

A shareholder current account sits among the third-party accounts of the Luxembourg standard chart of accounts: on the liabilities side under account 4712, debts to members and shareholders, and on the assets side under account 4212, receivables from members or shareholders. The liability side splits into account 47121 for the principal amount and account 47122 for accrued interest.

That split into two sub-accounts is not a bookkeeping refinement. It exists because principal and accrued interest do not follow the same regime: the principal is a cash flow, whereas accrued interest is an expense of the period, tied to the time during which the capital was made available and not to the payment date. An empty 47122 at 31 December on an interest-bearing current account is therefore, on its own, the sign of a cut-off that was never made.

The maturity split comes from the balance sheet layout of the amended law of 19 December 2002, which subdivides the other debts item between debts with a residual maturity of one year or less and debts with a residual maturity of more than one year. The standard chart of accounts carries that division into its numbering, with account 471 for the former and account 472 for the latter. The consequence is direct: a current account repayable at any time is a debt falling due within one year, and only a dated agreement setting a maturity beyond twelve months justifies the long line.

Companies subject to the standard chart of accounts draw up their balance sheet, their profit and loss account and their trial balance on the electronic financial data collection platform before filing with the trade and companies register. The current account is no exception: it is the standardised structure that forces a line to be chosen, and therefore a maturity. Preparing Luxembourg annual accounts makes that choice visible, where an internal trial balance will happily leave the balance in a suspense account.

Not every undertaking is subject to that chart. Guichet.lu excludes sole traders and partnerships, the société en nom collectif and the société en commandite simple, whose turnover excluding value added tax stays below EUR 100,000, special limited partnerships whatever their turnover, credit institutions, insurance and reinsurance undertakings and SEPCAVs. For those structures the cut-off and maturity logic still holds, but the numbering below does not apply.

Must a shareholder current account bear interest?

A shareholder current account in Luxembourg must be remunerated at market conditions: article 164(3) of the income tax law qualifies as a hidden profit distribution an advantage a member would not have received without that status. The provision covers advantages a member, partner or interested party receives directly or indirectly from the company.

The rule cuts both ways, and that is what surprises most often. On a credit account, the risk is interest that is too high: guichet.lu takes the example of shareholder funding remunerated at 20 % a year where the market rate is 4 %, and the excess fraction of 16 % risks recharacterisation as a hidden dividend distribution. On a debit account, the risk is interest that is missing: the same page lists an interest-free loan, or a loan at a rate below market conditions, among the recharacterised advantages, alongside a building made available without rent and a sale at a price below the value of the asset transferred.

The consequence is twofold, and it is the second half that files forget. The hidden distribution is added back to the taxable income of the distributing company, so it is not deductible there, and it is taxable in the hands of its recipient. There is no netting: the same euro is picked up on both sides, which makes a rate gap costly well beyond its nominal amount.

Where the shareholder is itself a company, the arm's length principle of article 56 of the income tax law applies on top of article 164, and article 56bis sets out how. Two enterprises are associated where one participates directly or indirectly in the management, control or capital of the other, or where the same persons participate in the management, control or capital of both.

Circular L.I.R. no. 56/1-56bis/1 of 27 December 2016 covers intra-group financing transactions, for which the agreed remuneration must correspond to the price that would have been charged between independent enterprises in comparable circumstances. The analysis then belongs to transfer pricing, with the documentation that goes with it.

In practice the rate is not defended by a general reference but by a file: amount, currency, term, ranking, security, credit quality of the borrower. The cut-off of intra-group loan interest accruals answers the same requirement of a dated agreement, and a contract signed after the period end to cover a flow of the previous period does not document that flow.

How far can a shareholder fund their company through a current account?

Shareholder current account funding in Luxembourg is tested against a maximum accepted debt ratio of 15/85: the assets held must be financed at least 15 % by equity and at most 85 % by debt, according to the guichet.lu page on the deductibility of interest.

Beyond that ratio, the Luxembourg Inland Revenue could recharacterise the excessive part of the debt as a hidden contribution, and the interest remunerating that excessive part as a hidden profit distribution. So the sanction is twofold here too: the corresponding fraction of interest loses its deductibility, and the amount itself changes nature, since it stops being a debt and becomes an equity equivalent.

The ratio does not look at all debt. Guichet.lu states that no debt ratio has to be respected where the loan is granted by a third party, in practice a bank: it is shareholder funding that is measured, not the liabilities as a whole. A company heavily indebted to its banker falls outside the test; the same company funded by its shareholder falls inside it.

The limitation on net exceeding borrowing costs in article 168bis of the income tax law sits on top of that test rather than replacing it. The two mechanisms answer different logics — one measures the structure of the balance sheet, the other caps an annual charge at 30 % of tax EBITDA or at EUR 3,000,000 — and a current account can fail one while satisfying the other. The detail of the cap is set out in our article on the interest limitation rule.

One last effect explains the attention the subject gets. Net wealth tax is computed on the value of all assets, rights and holdings making up the wealth at 1 January, after deduction of the debts burdening that wealth: a credit current account therefore reduces taxable net wealth, where a capital contribution does not. Recharacterised as a hidden contribution, it loses that effect. Minimum net wealth tax follows a different logic, based on the balance sheet total rather than on net wealth, as we explain in the article on minimum net wealth tax.

What happens if the shareholder current account is in debit?

A debit shareholder current account in Luxembourg means the company has advanced funds to its shareholder: with no interest, or at a rate below market conditions, the advantage is recharacterised as a hidden profit distribution. That distribution is capital income, just like an openly declared dividend.

What follows is mechanical. Withholding tax on capital income amounts to 15 % of the gross amount with no deduction, and the payer of the income operates it on behalf of the recipient at the date the income is made available. The return for withholding tax on capital income, form 900, and the payment are due within eight days of that date. Where the recipient meets the conditions of the parent-subsidiary regime of article 147, no withholding is to be operated; the detail is in our article on dividend withholding tax.

It is the date that hurts, more than the rate. For income whose distribution depends on a decision of a corporate body, the Luxembourg Inland Revenue places the making available at the payment date fixed by that decision or, where no date is fixed, on the day following the decision. A hidden distribution, by definition, rests on no decision: the advantage is deemed made available when it is granted. A debit current account that has been running for three periods therefore exposes the company to withholding tax due for periods already closed, and declared late by construction.

The useful correction is not an adjusting entry passed at the period end. It is a dated agreement, a justified rate and interest actually posted to 47122, or a repayment. We regularly see the opposite: a debit balance cleared at the period end by director's fees or a dividend decided after the fact, which reconstructs neither the date on which the income was made available nor the base of the withholding.

How is interest paid to the shareholder taxed?

Interest paid by a Luxembourg company on its shareholder's current account leaves without withholding tax: the company does not fall within the definition of a paying agent used by the final withholding tax on savings interest. It is the recipient who declares the income to the competent tax authorities.

The definition is precise, and it is what settles the question. A paying agent is the economic operator established in Luxembourg that pays interest, or secures the payment of interest for the immediate benefit of the beneficial owner, whether it is the debtor of the claim or the operator instructed to pay, and an economic operator is the person making those payments in the course of its profession or normal business activity — a bank, another financial sector professional, a fiduciary, a distributor.

Guichet.lu draws the consequence explicitly: a Luxembourg SARL paying interest to its managing member for the grant of a loan does not fall within that definition and pays the interest without operating any withholding. The page adds that a person or an undertaking occasionally paying interest to its creditors is not a paying agent.

On the recipient's side, the filing duty follows. A resident individual shareholder reports that interest in their tax return, as income from movable capital. A non-resident shareholder reports it to the tax authorities of their state of establishment. Companies with legal personality, resident or not, receive the interest due to them without withholding and declare it to the tax authorities of their registered office.

On the paying company's side, interest remains a deductible expense to the extent it matches market conditions and respects the two limits examined above. The deduction is lost on the excess fraction, and it is that fraction which the corporate tax return has to add back, not once an audit has started but when the taxable result is established. Confusing the two regimes — no withholding on interest, 15 % withholding on a hidden distribution — is the most expensive misreading on this subject.

The shareholder current account errors we correct most often

The shareholder current account errors we correct most often in Luxembourg do not bear on computing interest: they bear on the missing agreement, on the cut-off and on the balance sheet line chosen, three points an audit checks before any arithmetic.

The current account with no written agreement comes first. No cap, no maturity, no rate, no ranking: the company can then justify neither the maturity split on the balance sheet nor the rate paid, and the authorities remain free to reconstruct both. Drafting the agreement costs an hour; reconstructing it after the fact costs an audit.

Next come interest charges posted on payment. Account 47122 stays empty at 31 December although the capital was made available all year, and the expense lands in the following period. The error repeats from one period to the next and does not show up in a stable result: it shows up in the first period in which the current account is repaid.

The debit balance left as it stands is the heaviest. It often surfaces on a handover, after two or three periods, because private expenses were settled with the company card and charged to the shareholder's account with no interest and no maturity. Putting it right is not limited to an entry: it means dating the advantage, period by period, to measure the withholding at stake.

Finally, clearing a debit balance with director's fees or a dividend decided after the period end. The intention is sound, the effect on an already crystallised making-available date is nil, and the late decision adds a cut-off question to the withholding one. Reworking a history of that kind means going back to the bank statements and the supporting documents, item by item, before any correcting entry: it is a documentary exercise, and our engagement terms are set out on the pricing page.

The legal basis of the 15/85 ratio: guichet.lu states it as the maximum accepted ratio without citing any article of law, which makes it an administrative practice described by an official source rather than a written rule whose reference we could give; a file approaching it is handled with the competent tax office. The numbering of the sub-accounts of a shareholder current account falling due in more than one year, under account 472: the 471/472 division is established, the detail of the subdivision is not, on our reading.

And the quantified interaction of the debt ratio with article 168bis where both mechanisms bite in the same period, on which we take no position. These points can be checked in the coordinated text of the income tax law and in the Grand Ducal regulation on the standard chart of accounts on legilux.public.lu, and with the competent tax office for a contested rate or debt level.
