Frequent questions from Winterthur
We're founding a startup in Zurich — can you do it remotely?
Yes, formation runs largely location-independently; we coordinate the notary and the Zurich commercial register and you only appear where a signature genuinely requires it.
Can Planet handle accounting for a Winterthur tech company?
Yes, from the GmbH formation (CHF 2'500) through monthly bookkeeping from CHF 440 and the corporate tax return, we cover the full lifecycle.
How long does it take to form a GmbH?
Usually two to four weeks once all documents are in place — depending on your canton's commercial register. With prepared documents it goes faster; our checklist helps with that.
How much capital do I need?
For a GmbH at least CHF 20'000 (fully paid in), for an AG at least CHF 100'000 (of which CHF 50'000 paid in). The sole proprietorship has no capital requirement.
