Swiss VAT return — entirely on your device
Support
Last updated: 5 September 2026 · MWSTStudio · iOS und macOS · ch.babala.mwststudio
MWSTStudio calculates the Swiss VAT return on your device using the effective method or the net tax rate method: you enter turnover, deductions, acquisition tax and input tax, and the app derives the figures of the FTA’s official return form (items 200 to 510), flags inconsistencies, shows the due dates of the filing periods and produces the finished return as a PDF. The app runs on iPhone, iPad and Mac and needs no internet connection. It is not an accounting system and files nothing — you file the return yourself in the FTA portal.

So that we can help quickly
- Tell us the app, your device (e.g. iPhone, iPad, Mac, Android) and the operating system version.
- Describe what you did and what happened instead — a screenshot often helps.
- Do not include any personal or business data from the app — we do not need it, and the app does not transmit it to us.
Purchases and subscriptions
Purchases run exclusively through the store you obtained the app from. Refunds and subscription cancellations are handled by that store: on iPhone, iPad and Mac under “Settings → [your name] → Subscriptions” or via reportaproblem.apple.com. We are happy to help with questions about this.
