Srl partner and INPS contributions: Cassation on profits

Srl partner and INPS contributions: Cassation on profits

The Supreme Court of Cassation has ruled that a partner in an Srl (an Italian limited liability company) who works regularly in the business does not owe INPS contributions on profits retained in reserves. The obligation arises only where the company’s income is attributed to the partner and the partner reports it for personal income tax (IRPEF) purposes. The ruling affects many closely held companies. It also gives working partners a clearer basis for planning dividends and social security contributions.

The case and the legal framework

The dispute arose from notices of payment issued by INPS, the Italian social security institute, to the sole shareholder and director of an Srl. INPS sought contributions to the traders’ scheme (gestione commercianti) on the profits the company generated in 2015 and 2017. The shareholder was enrolled in the scheme because she took part in the company’s activity on a habitual and predominant basis. The company, however, had not distributed the profits. It had retained them in its accounts and had not opted for tax transparency.

The Court of Appeal of Milan had sided with the shareholder. In its view, an Srl remains a capital company even when it has a single shareholder. In capital companies, moreover, tax and social security look only at income that is actually distributed and received. INPS challenged the decision on a single ground of appeal.

The relevant provision is Article 3-bis of Decree-Law no. 384/1992. It ties the annual contribution to the totality of business income “reported” for IRPEF purposes. This provision widened the contribution base compared with Law no. 233/1990, which took into account only the income from the activity giving rise to enrolment.

The legal issue

INPS argued that the income generated by the company should count towards the working partner’s contributions in its potential amount, not in the amount actually received. According to the Institute, leaving the decision on distributing profits to a sole shareholder would let the person liable for contributions determine the contribution base. That outcome, it argued, conflicts with the non-waivable nature of social security obligations and with the principle of solidarity.

The Supreme Court of Cassation therefore had to determine the conditions under which income reported by an Srl is attributed to the partner who works in the business, and so falls within the contribution base.

The decision and the ratio decidendi

The Labour Division, by judgment no. 25377 of 16 September 2026, dismissed INPS’s appeal. The principle of law is clear. A partner who works habitually and predominantly in an Srl pays contributions on the share of business income that the company reports for tax purposes, that is attributed to the partner in proportion to the partner’s shareholding, and that the partner reports for IRPEF. INPS must prove that the income was attributed to the worker, either through receipt of the profits or through the company’s option for tax transparency (Articles 115 and 116 of the Italian Consolidated Income Tax Act, TUIR).

The Court gives three reasons for this approach.

The wording of the law. The statute refers to income “reported” for IRPEF purposes. In the Court’s view, this is a technical and verifiable criterion, chosen deliberately by the legislature and already present in earlier social security legislation. Retained profit remains income of the company, which reports it for corporate income tax (IRES) purposes. It is not income of the partner. Reading “reported” as “obtainable” would deprive the word of meaning. The Court also invokes the statutory reservation in Article 23 of the Constitution: a compulsory financial charge requires a clear legal basis, both for its existence and for its amount.

Consistency with the tax system. The Constitutional Court (judgment no. 354/2001) recognised the legislature’s aim of aligning the tax base with the contribution base. If the tax authorities do not attribute income to the partner, social security cannot treat it as the partner’s income.

The difference between company types. In partnerships, income is attributed to the partners by transparency, regardless of receipt. For this reason, a limited partner in a Sas (a limited partnership) must include that income in the contribution base. In capital companies, by contrast, attribution occurs only when profits are received or when the company opts for transparency. The Court considers it reasonable for social security rules to follow this distinction.

The Court then rejected the objections raised by INPS and the Public Prosecutor’s Office. The aim of widening the contribution base does not permit indiscriminate extensions. Nor is there any implicit intent to avoid contributions in retaining profits, since businesses have many reasons not to distribute them. Finally, the benefit to future pensions does not allow the limits set by the law to be overridden, and Article 38 of the Constitution remains safeguarded by minimum contributions.

Operational implications

The ruling confirms a distinction already present in case law. A partner in an Srl who does not work in the business does not include profits in the contribution base. A working partner, by contrast, includes only the share of income that the tax system attributes to them.

Three practical points emerge for businesses and partners:

• Dividend policy. Retaining profits in reserves does not generate additional INPS contributions. Distributing profits, by contrast, triggers the obligation to report the income and, for a partner enrolled in the scheme, to pay contributions on the amount received.
• Option for tax transparency. Choosing this regime means income is attributed to the partners regardless of receipt, with direct effects on contributions as well.
• Disputes with INPS. The burden of proof lies with the Institute, which must show that profits were received or that the company opted for transparency. In an inspection, corporate records, resolutions on the allocation of profits and tax returns carry decisive weight.

The ruling does not rule out action by the legislature or the Institute to counter abusive use of profit retention. For now, however, the Court requires that any extension of the contribution obligation have a clear basis in the law.
