Understand our tax support →Outsource your bookkeeping, corporate tax return and, as needed, VAT and payroll. Keep a clear view of your finances.
View SME packages →Your corporate and personal tax returns serve different purposes. We specify from the outset which tax services are included in your engagement.
We prepare your company’s annual accounts and corporate tax return. Companies in Vaud file electronically through the cantonal e-DIPM service.
The monitoring of tax instalments and correspondence with the authorities are agreed according to your circumstances. The aim is to align your tax obligations with your results, without waiting until year-end to discuss them.
The corporate tax return is included in our Sàrl and SA packages.
Corporate tax returns: Canton of Vaud →Your sole proprietorship’s year-end accounts provide the business figures needed for your personal tax return. We review your expenses, supporting documents and the information to submit based on your circumstances.
Do you work in Nyon but live in another canton? Mention this during our first discussion: both your business location and your place of residence must be considered when reviewing your situation.
Year-end accounts are included; the personal tax return is quoted separately.
Supporting documents: Canton of Vaud →Tell us whether your request concerns a company, a self-employed activity or a personal tax return. We will review your needs and confirm the services and fees before starting.

To organise the accounts of your self-employed activity.
To outsource your company’s accounting.
Your accounting and tax support is supervised by Swiss certified accountants.
Accounts are updated every month using the documents you provide.
The fee depends on document volume and the complexity of your situation. Year-end closing and annual financial statements are included in all our packages. The corporate tax return is also included for Sàrl and SA companies; self-employed individuals’ personal tax returns remain outside the package. Payroll and any handover work are quoted according to your needs and detailed in the proposal.
When choosing an accountant in Nyon, check what is included in the engagement: day-to-day bookkeeping, year-end closing, tax returns, VAT and access to a dedicated contact.
Monthly fees can only be compared when document volumes and included services are the same. Also ask how payroll, one-off advice and the handover are charged.
Our app brings your documents together and makes communication with your accountant easier. Send us your invoices and supporting documents as you go, from your office or while travelling.
We hold regular phone or video reviews to discuss your figures, prepare for deadlines and answer your questions. The frequency is tailored to your business.
We prepare the list of documents to collect and coordinate the handover with your agreement. The timeline takes account of your current contract and the state of your records.
Business activity, document volume, VAT, employees and expectations: we review your needs.
You receive the scope of the engagement, fees and working arrangements before committing.
We help you get to grips with our app, organise any necessary handover and schedule your next reviews.
