Cabinet fiscal Laetitia Mazanek

A regional practice focused on personal and business tax

Cabinet fiscal Laetitia Mazanek operates from two locations in Valais (Wallis canton): Sion and Monthey, towns in the Swiss-French speaking region. The practice is owned and run by Laetitia Mazanek, a sole practitioner who explicitly offers "Conseils économiques et fiscaux pour particuliers ou entreprises" (financial and tax advice for individuals and businesses) and "personal relocation" (Auswanderungsberatung via the English tagline). The practice description emphasizes a personal, combative approach: "Combative, c'est avec force et passion que je me bats pour défendre au mieux vos intérêts" (I fight with strength and passion to defend your interests).

For someone arriving or relocating to Valais

The explicit mention of "personal relocation" in the English tagline signals a focus on arrivals and cross-border tax matters. Mazanek's service list includes domiciliation de personnes étrangères,providing a Swiss domicile address for foreign persons,which is relevant for expatriates or remote workers from abroad who need a Swiss address for tax registration and Swiss banking purposes but may not have bought real estate yet. This service answers a practical arrival need: a Swiss resident address to satisfy cantonal registration and tax-filing requirements.

The practice also covers tax declarations for Swiss residents, whether citizens or established expatriates, and offers optimization and planning for personal and business situations. A blog post titled "Le Valais, terre d'accueil romande des contribuables fortunés" (Valais, the French-speaking Swiss haven for wealthy taxpayers) suggests knowledge of the particular tax situation that draws wealth to the canton,an implicit signal that the practice works with high-net-worth arrivals and relocations into Valais specifically.

Professional background and service scope

Mazanek began her career in banking (finance sector) for a decade, then moved to Risk Management. After gaining experience at a large fiduciaire (a Swiss accounting and tax firm), she opened her independent practice to offer "personalized service in line with my entrepreneurial values." That background in both banking and risk management, combined with fiduciaire experience, suggests capability across personal tax, business planning, and financial risk,three domains that typically require separate firms.

The full service list covers the arc of a business lifecycle and personal wealth events. For businesses: creation, administrative support, and liquidation (closing). For individuals: tax optimization, declarations, real estate taxation, donations and succession planning. The practice also offers business management advice (Conseils en Risk Management et gestion d'entreprise) and accounting/bookkeeping services (Tenue de la comptabilité et bouclement). The breadth means the practice can serve clients end-to-end,from startup through growth and eventual sale or succession,rather than only at tax time.

Valais-specific expertise and focus

Three published blog posts highlight the practice's niche: two focus on Valais real-estate taxation. One asks "Etre propriétaire d'une résidence secondaire en Valais: conséquences fiscales" (owning a secondary residence in Valais: tax consequences),relevant for arrivals or wealthy individuals buying second homes in the canton. Another is titled "Impôt sur les gains immobiliers" (real estate gains tax), and a third covers real-estate-specific audit questions. A fourth post addresses "L'uniformisation des lois fiscales" (tax law harmonization), suggesting engagement with Swiss-level tax policy changes.

The blog's real-estate and wealth-in-Valais focus suggests Mazanek has built practice depth in property taxation,a major consideration for someone buying in Switzerland and asking how that purchase and eventual sale affect Swiss and home-country taxes. For an arriving wealthy individual or a remote worker relocating to Valais to live and build wealth there, that expertise is directly relevant.

Languages and client base

The practice operates in French and English (FR / EN), making it accessible to English-speaking arrivals and expatriates without requiring French fluency. Mazanek's own training (banking, international risk management, work with a large fiduciarie) suggests exposure to international clients and cross-border transactions, though the site does not specify geographic scope or typical client profile.

Mazanek states her current clients include "indépendants, d'entreprises locales ou internationales et de particuliers domiciliés ou non en Suisse" (self-employed, local and international companies, and individuals domiciled or not in Switzerland). The explicit mention of clients not domiciled in Switzerland confirms that the practice advises foreign residents, including those arriving or considering Valais, consistent with the relocation focus.

What the site does not specify

No pricing is published. Potential clients would need to contact Mazanek directly to understand fee structure, whether the practice charges hourly, by the return/project, or by retainer. The site does not clarify the scope of risk-management advice (whether it extends to business insurance, corporate governance, or solely financial risk), the typical complexity of real-estate cases the practice handles (single residential properties vs. commercial development), or turnaround time for different services.

The practice's geographic location (Valais) and focus on Valais real-estate taxation raises an implicit question: while the site serves international clients, would a non-resident arriving in a different canton find the firm's depth less directly relevant? The domiciliation service is available regardless of canton; tax services and succession planning also apply broadly. But the real-estate focus and blog content suggest the practice's deepest expertise is in Valais properties and residents.

Who this suits

This listing is relevant for individuals arriving in Valais, whether to relocate permanently or to buy property there. The domiciliation service addresses a near-term arrival need. Someone relocating with significant wealth or real-estate holdings would benefit from Mazanek's specialization in property taxation and personal wealth structuring. Expatriates and cross-border workers establishing Swiss tax residence in Valais could engage the firm for arrival tax planning and ongoing compliance. Self-employed individuals or small-business owners (particularly those operating internationally) would benefit from the combined tax, accounting, and business-advice scope. Someone seeking end-to-end support,from startup through growth, property purchase, and eventual succession,would find a rare all-in-one partner. By contrast, a client in a different canton might find the Valais-specific real-estate expertise less directly useful, or might prefer a practice with equivalent depth in their own canton's tax particulars.

Domiciliation and the foreign-resident pathway

The explicit mention of "domiciliation de personnes étrangères" (domiciliation for foreign persons) deserves emphasis for arrivals. Domiciliation allows a foreign resident or remote worker to establish a Swiss address for administrative and fiscal purposes without owning real estate. This is a practical arrival step: you register for cantonal tax purposes, open Swiss bank accounts, and meet Swiss residency requirements while your housing is still temporary or elsewhere. Mazanek offers this service directly, so a newly arrived expatriate can retain the firm through both the domiciliation phase and any subsequent property purchase or wealth transfer.

Mazanek's own background,starting in banking, moving to risk management, gaining fiduciary experience, then opening an independent practice,mirrors the diversification that many arrivals require. Someone relocating to Valais with savings, rental income, or investment portfolios needs to understand Swiss wealth-tax implications quickly. Mazanek's background in banking and risk management suggests fluency with investment and cash-flow structuring, not just tax form-filling.

Engagement style and relationship

The site emphasizes a combative, engaged relationship: "with strength and passion I fight to defend your interests." This frames the practice as an advocate, not merely a compliance box-ticking service. For an arriving expatriate managing a complex transition or negotiating with Swiss tax authorities as a foreign resident, that advocacy stance may matter. The practice explicitly welcomes clients "domiciled or not in Switzerland," confirming that you do not need to have settled your permanent housing or residency status before reaching out.

The site's focus on client relationships and trust also signals that this is not a high-volume, algorithm-driven practice. With offices in both Sion and Monthey, Mazanek has chosen to remain geographically distributed across the Valais region, likely to preserve direct client contact rather than consolidate into a single headquarters. That commitment to in-person availability is less common in modern tax practices and may matter if you prefer face-to-face tax planning over video calls.
