Deloris AG

Deloris AG is a Zurich-based tax consultancy at Zurich Enge specializing in tax advice for expats and personal finance for arrivals to Switzerland. The firm positions itself around two core services: Swiss tax returns and personal financial planning delivered through a 360-degree-lifecycle approach. Deloris serves private individuals, entrepreneurs, and international clients, with particular expertise in the German-speaking cantons. The team at Zurich Enge has worked with 3,800 clients to date on optimizing their tax liability.

Getting Started as an Arriving Expat

Deloris explicitly markets to people newly in Switzerland asking "New in Switzerland?" and describes settling into a new environment while focusing on career as a context where many questions arise. For this cohort, the firm offers expatriate tax returns and Swiss financial planning as its opening services. The firm promises security and time in return for managing your tax affairs and personal tax matters, and aims to help you stay compliant with Swiss tax regulations while ensuring your tax situation is structured as efficiently as possible. The firm's FAQ emphasizes that Deloris understands the complex tax situations that local and international clients face, building on years of experience in Swiss tax practice.

The firm's process appears straightforward: contact Deloris, have an initial review of your situation and documents, gather and structure relevant tax information, clarify open points before the return is prepared, review the completed return, and understand key assumptions and deductions. The FAQ emphasizes that the ideal experience should feel straightforward with less back-and-forth, fewer uncertainties, and a clear sense that filing is handled professionally from start to finish.

The firm does not specify a timeline for the initial review or how long a complete tax return process typically takes from first contact to submission.

Tax Services and Personal Finance

Deloris's tax return services include preparation of Swiss tax returns, review of existing tax returns, identification of possible deductions, and support with tax authorities. The firm positions professional support as especially helpful when tax situations are no longer straightforward, which often includes cases with multiple sources of income, investment portfolios, real estate, foreign bank accounts, share-based compensation, changes in marital status, relocation between cantons, or international links through work or assets abroad.

The firm emphasizes that even when the tax return itself looks manageable, the real value of professional advice often lies in identifying issues before they become costly. A well-prepared return can help reduce the risk of incomplete disclosures, missed deductions, avoidable follow-up questions from tax authorities, or unnecessary stress close to the filing deadline.

Deloris's personal finance service applies a 360-degree-lifecycle approach to make money matters in Switzerland predictable and painless. This service covers retirement planning to tax compliance, though the site does not detail whether retirement planning means investment advisory, pension structuring, or insurance coordination, or exactly what the lifecycle approach entails.

Handling Complex and Corrected Returns

Deloris addresses scenarios beyond routine filing. For complex personal tax situations, the firm explains that complexity can arise from securities, property ownership, self-employment income, foreign assets, foreign pension elements, bonus structures, or tax questions linked to relocation and international employment. In these cases, work involves understanding how different parts of your financial situation interact, what should be disclosed where, and which supporting documents should be prepared clearly to avoid unnecessary questions later. The firm frames this as where experienced tax support becomes valuable, requiring structure, accuracy, and judgment.

For clients who have already submitted a tax return and are unsure whether it was done correctly, Deloris offers a review and correction service. The firm notes that clients sometimes realize only after submission that something may have been missed, declared incorrectly, or not presented clearly enough. This might involve deductions, securities, foreign assets, property-related items, or questions triggered by a tax assessment or a letter from the tax authority. Deloris says the first step is usually to review what was filed and identify whether the issue is procedural, factual, or strategic. In some cases, clarification or supporting documentation suffices; in others, assessment may reveal that a correction, objection, or follow-up response is appropriate.

What Deloris Does Not Publish

The site does not list specific fee structures, hourly rates, or pricing bands for any service. No package pricing, tiered fees, or cost estimates are published. The FAQ and main pages do not discuss minimum engagement amounts, retainer fees, or how billing relates to case complexity.

The firm does not name individual team members beyond the Zurich Enge location, or describe their credentials, educational backgrounds, or areas of specialization within tax practice. No client references or case study details are provided beyond one testimonial from Rachel de Leon (dated January 27, 2025, rated 5 out of 5), who says "The Deloris team took me by the hand and carefully walked me through the entire tax filing process." The firm does not publish accreditations or professional memberships.

The site emphasizes service quality and client confidence but does not specify guarantees, performance targets, or what "structured efficiently as possible" means in terms of tax savings or outcomes. It does not state whether Deloris handles VAT compliance, social insurance questions for self-employed arrivals, immigration tax considerations, or other specialized arrival scenarios. The scope of "personal finance" beyond retirement planning and tax compliance is not detailed. For clients with urgent situations, it is unclear whether expedited processing is available or what rush fees might apply to accelerated work.

Who This Suits and Who It Does Not

Deloris is built for arrivals to Swiss German-speaking cantons who need to stabilize their first Swiss tax return or who face complex situations (multiple income sources, property, international assets, relocation between cantons). If you are relocating to the Zurich region or another German-speaking canton, speak English or German, and want professional guidance through your tax obligations with confidence that complications will be handled correctly, Deloris is a strong fit.

The firm is less suited to those seeking published pricing upfront, detailed team credentials before first contact, or specific guarantees about tax savings. Because fees are not published and complexity is a variable, the cost of engaging Deloris cannot be estimated from the site alone. Those wanting to evaluate advisor credentials, specific professional designations, or a detailed service-level agreement should ask explicitly during the initial review. The firm's expertise is centered on German-speaking cantons, so those relocating to French or Italian-speaking regions may want to verify geographic coverage before engaging.
