Withholding Tax Refund and Declaration

Withholding Tax Refund and Declaration in Switzerland

Withholding tax in Switzerland constitutes a fiscal mechanism levied at source on certain income, notably interest, dividends and lottery winnings. This levy, generally set at 35%, represents a guarantee for the Swiss tax administration against tax fraud. For natural persons domiciled in Switzerland and legal entities with their registered office in Switzerland, this amount is not definitively lost. Swiss legislation provides for specific refund procedures depending on the status of the taxpayer. Our law firm regularly assists taxpayers in these administrative steps which require precision and in-depth knowledge of the Swiss legal framework.

Legal Foundations and Principles of Swiss Withholding Tax

Withholding tax finds its legal basis in the Federal Act on Withholding Tax (WTHA) of 13 October 1965 and its implementing ordinance. This source tax constitutes a pillar of the Swiss tax system, designed primarily as an instrument for combating tax evasion.

The standard rate of 35% applies to three main categories of income:

• Income from movable capital (dividends, interest on bonds, bank deposits)
• Winnings from Swiss lotteries exceeding a certain amount
• Certain insurance benefits

The distinctive feature of this tax lies in its refundable nature under certain conditions. It is not a definitive tax charge but an advance on ordinary income or profit tax. This characteristic distinguishes Swiss withholding tax from many other source levies practised abroad.

The system rests on three main actors:

• The debtor of the taxable benefit (for example a company paying dividends)
• The beneficiary of the benefit (the investor or depositor)
• The Federal Tax Administration (FTA)

The jurisprudence of the Federal Supreme Court has clarified the interpretation of many provisions of the WTHA over the decades, creating a sophisticated legal corpus that practitioners must master to effectively assist their clients. Recent legislative changes, notably with the corporate tax reform, have brought significant changes in the application of certain rules relating to withholding tax.

Refund Procedure for Resident Natural Persons

For natural persons with their tax domicile in Switzerland, the refund of withholding tax is generally effected through the annual tax return. This procedure, although relatively simple in principle, requires particular attention to deadlines and administrative formalities.

Prerequisites for Refund

The taxpayer must satisfy several requirements to claim a refund:

• Be domiciled in Switzerland at the end of the relevant tax period
• Correctly declare the income subject to withholding tax
• Be the beneficial owner of the income concerned
• Respect the three-year limitation period for the refund application

The concept of beneficial owner is of paramount importance in administrative practice. The FTA verifies that the applicant genuinely holds the right of economic enjoyment over the declared income, and is not acting merely as a nominee or intermediary.

Practical Modalities of the Application

In most cantons, the refund application is integrated directly into the ordinary tax return. The taxpayer must:

• Complete the specific annex concerning income from movable capital
• Attach supporting documents (bank attestations, account statements)
• Clearly indicate the withholding tax amounts levied

Once the application has been processed by the cantonal tax administration, the amount of withholding tax is either reimbursed directly to the taxpayer or offset against their cantonal and communal taxes due.

Practice shows that certain situations can complicate the procedure, notably when income derives from particular legal structures such as investment funds or in cases of dismemberment of ownership (usufruct/bare ownership). In these specific cases, assistance from our law firm optimises the chances of obtaining full refund of the levied amounts.

Specificities for Legal Entities and Institutional Investors

Swiss legal entities benefit from a particular regime concerning the refund of withholding tax, with procedures adapted to their legal status and activity.

Ordinary Procedure for Commercial Companies

For companies limited by shares (AG) and limited liability companies (GmbH) with their registered office in Switzerland, the refund is effected via a specific form (form 25) to be addressed directly to the Federal Tax Administration. The application must be accompanied by supporting documents and submitted within three years of the end of the calendar year in which the income fell due.

Companies must satisfy several cumulative conditions:

• Have their statutory registered office in Switzerland
• Regularly account for income subject to withholding tax
• Prove their status as beneficial owner of the income

Administrative practice pays particular attention to the examination of complex holding structures and intra-group relationships to ensure the absence of abuse of law.

Special Case of Institutional Investors

Pension funds, provident foundations and other occupational pension institutions benefit from specific treatment. These entities may request the refund of withholding tax even when they are exempt from profit tax.

The procedure involves:

• Use of form 25 adapted to their status
• Presentation of the tax exemption decision
• Detailed justification of income subject to withholding tax

For large institutional investors carrying out numerous transactions, the declaration procedure (in lieu of levy then refund) may constitute an advantageous alternative. This option avoids the initial levy of withholding tax on certain income, subject to prior authorisation from the FTA.

International groups present in Switzerland must pay particular attention to cross-border aspects and double taxation conventions which may impact the modalities of withholding tax refunds. Our law firm has recognised expertise in these complex issues at the interface of Swiss and international tax law.

Declaration Procedure as an Alternative to Refund

The declaration procedure represents an alternative to the classic system of levy then refund of withholding tax. This method, introduced to simplify financial flows and reduce administrative burdens, proves particularly relevant in certain configurations.

Principles and Legal Framework

This procedure allows the debtor of the taxable benefit (for example a company distributing dividends) to discharge its tax obligation not by paying withholding tax to the FTA, but simply by declaring the amount of the taxable benefits.

The legal framework rests on:

• Arts. 20 et seq. WTHA
• Arts. 24 et seq. of the implementing ordinance
• Administrative circulars from the FTA specifying the practical modalities

Unlike the standard system, the declaration procedure avoids the temporary mobilisation of liquidity, which represents a significant financial advantage, particularly for large-scale transactions.

Common Application Situations

The declaration procedure applies principally in the following contexts:

• Dividend distributions between Swiss companies where the participation is at least 20%
• Dividend payments to foreign companies benefiting from double taxation conventions, under certain conditions
• Insurance benefits paid by Swiss companies
• Certain interest paid between entities of the same group

For international relationships, this procedure interfaces with the provisions of tax conventions and may require specific authorisations.

Application of the declaration procedure generally requires a prior application to the FTA, which must be submitted within strict deadlines (generally 30 days before the due date of the taxable benefit). Once authorisation is obtained, it can often be renewed for similar future transactions.
