A Local Tax-Filing Service for the Berner Oberland

Optamis GmbH is a tax-filing service based in Thun serving the Berner Oberland region since 2009. The firm handles tax return preparation for private individuals across all employment categories: salaried workers, self-employed, students, apprentices, and retirees. The focus is on speed and affordability rather than complex international planning or wealth structuring. For 17 years, the firm has filed returns at transparent, fixed prices, making it possible to budget exactly what you will pay before you call.

The firm's positioning emphasizes local accountability. They are not a remote online service; they operate in Thun, understand the cantonal tax system intimately, and have 17 years of familiarity with how the Berner Oberland's revenue office handles returns. That familiarity translates to fewer errors and faster processing.

For New Arrivals in the Thun Region

An arrival to Thun faces a three-month deadline to file a tax declaration with the Canton of Bern. That timeline is rigid and violation incurs penalties; if someone lands in Thun in July, they have until October to file. Optamis exists to meet this deadline without the arrival having to navigate an unfamiliar cantonal system alone.

The firm's marketing emphasizes that they see the same mistakes repeatedly: not the complex structures that require expert judgment, but common oversights that cost people hundreds of francs in unnecessary taxes. A person new to Switzerland often does not know which deductions apply to their situation (childcare, commuting costs, professional expenses, union dues, insurance premiums), and that gap can inflate tax bills needlessly. Optamis promises to apply all available deductions to your situation, not just the ones you know to ask for or that the form itself highlights.

The key practical advantage for an arrival is the checklist. After you contact them, Optamis sends you a structured checklist matching the cantonal form's categories. You gather documents against that checklist (pay stubs, receipts, donation records, interest statements) and send them to Optamis. No guessing what you need; the checklist tells you exactly what to collect and what each item documents. That clarity reduces the back-and-forth typical of a first-time filer trying to work out what the form wants.

Optamis then files your return directly with the canton. The turnaround is 10 business days from receipt of your complete documents. You receive a copy of what they filed, so you can verify the information before it goes to the authority. If the canton's assessment arrives later and you want to challenge it, Optamis also helps with objections.

What the Firm Charges and How It Works

For new customers filing the 2025 tax return (year 2024 income) in 2025, Optamis charges a flat 69 francs. The firm emphasizes that they have held this price constant for over 10 years; the rate did not rise for 2026. This introductory price is positioned to let new clients test the service before committing to ongoing relationships. The firm positions this rate as an incentive to build new-customer relationships.

More complex situations would cost more. The site does not quote prices for self-employed, multiple income sources, or significant investment income; you would contact the firm for a quote in those cases. However, the firm's emphasis on simple returns suggests they are not the right fit for complexity beyond a standard salaried person.

The firm's checklist-based workflow is designed for efficiency. You gather the documents once against a single checklist rather than trying to assemble a return yourself or emailing back and forth to clarify what you need. The firm does the assembly and files it directly with the canton. Optamis handles correspondence with the cantonal tax office if questions arise, so you do not have to navigate that in German if you are not fluent.

One service the site highlights is applying for a filing extension if you need more time. The canton grants extensions on request; Optamis can request it on your behalf if 90 days is not enough to gather documents. This matters if you land mid-year and work or personal circumstances make gathering documents hard; an extension buys you time without penalty.

What the Service Does Not Cover

Optamis does not publish prices for complex situations. If you are self-employed, have rental income, or worked for multiple employers in the year, you need to contact them for a quote. That prevents you from budgeting upfront if your situation is not straightforward.

The site does not offer tax planning or tax optimization, as larger firms do. Their scope is narrower: they file your return as it stands and help you claim deductions you might miss. They do not restructure your affairs to lower next year's tax, do not advise on pension strategies, and do not handle investment planning. A person earning salaried income does not need those services; someone with business income or substantial assets might.

The firm serves the Thun area and Berner Oberland explicitly. It is unclear whether they take clients in other cantons; contact them to confirm if you are outside the region. Thun is in Bern canton, and the form they work with is the Bern cantonal return; if you live in Aargau or Basel, they are unlikely to serve you even though you might be close geographically.

Communication is in German; there is no indication of English-language capability. If German is not your strong language, a firm with English-speaking advisers may be clearer and faster.

Who It Suits and Does Not

Optamis is an excellent fit for a salaried arrival in the Thun area with modest income and no complicated side income. The low introductory price makes it easy to try. If you are in the region and have a standard tax situation, this service handles your deadline without hassle. The 10-business-day turnaround is also valuable if you need your copy of the filed return quickly for a visa extension, employment verification, or a financial application.

It is less of a fit if you are self-employed, have significant investment income, or need tax restructuring advice. For those situations, a larger firm with broader expertise is more useful. And if you are in another canton (Basel, Geneva, Zurich), other regional firms serve your area and may be more convenient, even if Optamis were willing to take your case.

The service is also less useful if you need advice in English. The site is in German, and communication with the firm appears to be conducted in German. If German is not your strong language, a firm with English-speaking advisers or advisers who speak your language may be clearer and faster, reducing the total time and hassle of getting your return filed correctly.
