Detailed approach and deliverables for tax advisory and tax return services

Scope, objectives and priorities

Our work on tax advisory and tax return services starts with a precise review of your flows and operating model so we can define a clear scope, realistic timeline, and priorities that make a measurable difference. In Geneva, Lausanne and French-speaking Switzerland, we work with SMEs, self-employed professionals, expats and executives who want to secure tax advisory without adding internal complexity or losing visibility on key decisions. The core deliverables typically cover tax returns, VAT filings, withholding tax and tax planning, with an ongoing focus on data quality and traceability. We embed requirements tied to federal and cantonal tax rules, VAT and reporting obligations from the beginning to avoid late-stage fixes and compliance risk. Depending on your context, we organize the collection of annual accounts, salary certificates and deduction evidence and implement simple routines to keep records complete and reliable.

We rely on tax calendars, simulations and compliance checklists when they add clarity, while staying compatible with your current stack if you prefer a hybrid approach. Every engagement begins with a short diagnostic that clarifies constraints, expected gains, and decision points, then translates into a written action plan. We favor direct communication and regular checkpoints so trade-offs remain visible and timelines stay under control. Our methods adapt to activity cycles, operational peaks, and cantonal constraints, with a pragmatic follow-up rhythm. The goal is to deliver compliance, optimization and reduced risk while reducing the administrative load on your teams.

When external stakeholders are involved, we coordinate exchanges and prepare the synthesis materials they expect. We explain options, impacts, and trade-offs clearly so decisions stay aligned with your strategy. Costs are driven by complexity, transaction volume, and coordination needs; we make those drivers explicit early on. We provide reporting formats suited to your governance, with concrete indicators and actionable recommendations. When the context changes (growth, funding, restructuring), we adjust the setup without starting over.

The engagement stays centered on your priorities: compliance, efficiency, and reliable day-to-day execution. We document decisions in a clear way so each choice is defensible and continuity is preserved. Finally, we outline the next steps so the post-engagement phase is smooth and improvements remain durable.
