Sarah Prieur

Swiss certified accountant · Tax and VAT specialist

I support companies, holding companies, self-employed professionals and entrepreneurs in their tax decisions. Intercantonal tax, transferring a sole proprietorship into an LLC, the owner’s and family’s circumstances: I assess the issues as a whole.

My principles

Three principles that shape my work.

Engagement quality rests on technical precision, visible organisation and communication clear enough to address questions before the deadline.

Rigour is non-negotiable

A year-end closing, tax return or VAT return must be documented, consistent and delivered within the deadlines applicable to the engagement.

The relationship is part of the service

A business owner should know their file’s status, what is missing and which decision is theirs. Availability and transparency are therefore essential.

Quality is built as a team

Continuing education, sharing technical issues and proportionate checks enable each colleague to take responsibility for their work.

My daily work

From financial audit to leading an accounting firm’s operations.

My role connects two responsibilities: addressing sensitive technical matters and ensuring a reliable working method across the team.

Precision is not optional. It must remain visible in the records, the deadline met and the explanation given to the client.

Eight years in audit at PwC Switzerland

I spent eight years in financial audit at PwC in Geneva. My assignments involved SMEs, industrial groups, watchmaking businesses and private banks.

These environments taught me to handle complex transactions methodically, document controls and preserve confidentiality. I obtained the Swiss federal accountancy diploma while working.

An operational role at Karpeo

At Karpeo, I supervise client work and team organisation. My direct involvement focuses particularly on company and holding tax, intercantonal situations, self-employed professionals’ and families’ tax, and complex VAT questions. I also contribute to year-end closing and payroll files requiring detailed analysis.

I also coordinate assignment allocation, continuing education and process improvement. The aim is for quality standards to reflect risk and complexity rather than the client’s size.

Practice suited to Geneva’s context

Geneva brings together distinctive situations: cross-border employees, international business owners, groups spanning jurisdictions and recurring social insurance or tax-at-source questions.

My work involves gathering relevant information, distinguishing general rules from the specific case and directing clients to the formalities or specialists needed when a topic extends beyond the firm’s scope.

Professional background

A career focused on audit, quality and client relationships.

Audit experience in Geneva, followed by daily supervision of client work and the Karpeo team.

Tax and VAT

A complete view of your tax, business and personal.

A business decision may also affect its owner and their family. My role is to connect these issues, explain the options and prepare formalities suited to your situation.

Companies and holdings

Company and holding taxation

Tax returns, profit and capital tax, participations and distributions: I help companies and their owners meet obligations and analyse decisions.

Several cantons

Intercantonal tax

Activity in several cantons, establishments or a change of registered office: I examine tax connections and intercantonal allocation to understand the implications for the company and owner.

Self-employment and development

From sole proprietorship to LLC

I advise on self-employed taxation and transferring the business into an LLC. The analysis covers tax consequences of transferring assets and liabilities, hidden reserves and conditions to examine before proceeding.

Owner and family

Taxation of entrepreneurs and their families

The business and household situations are connected. I examine salary and dividends, pensions, assets and private tax returns, taking account of family circumstances.

VAT specialist

VAT: from obligations to complex situations

Registration, method selection, returns, input tax recovery and cross-border transactions: I address both routine questions and situations requiring detailed VAT analysis.

International context

Cross-border workers and situations

I support tax questions for cross-border workers and international residents, particularly tax at source and their personal and professional situation, working with relevant specialists where needed.
